    To minimize the effects of weightlessness and partial gravity, astronauts use several counter measures to maintain health and fitness. One counter measure is exercise to help reduce or eliminate muscle atrophy and bone loss, and to improve altered cardiovascular function. This video shows astronauts on the International Space Station (ISS) using the stationary Cycle/ Ergometer Vibration Isolation System (CVIS), the Treadmill Vibration Isolation System (TVIS), and the resistance exercise device. These technologies and activities will be crucial to keeping astronauts healthy and productive during the long missions to the Moon. Mars, and beyond.

    Full Text Available Undoubtedly, no regular practice of physical exercise is one of thefactors that determine the global epidemics of weight excess andobesity in all age groups. Taking up physical activities regularlysince the initial stages of life (childhood, during adolescence andmaintaining them in adulthood – from young adults to over 50 yearsof age - is essential to assure an appropriate control of weight andbody fat. The general recommendation of physical exercise for goodhealth is to practice at least 30 minutes of moderate activities, atleast five days a week, and preferably every day. When the purposeis to lose and control weight in overweighed and obese individuals,the minimum practice should last 60 minutes/day, preferably 90minutes/day, at least five days/week, in a continuous or accumulatedmanner. Physical exercise is associated with several physical,psychological and social benefits that justify it inclusion as a crucialstrategy to prevent and treat overweight and obesity in any agegroup. Apart from moderate aerobic physical exercise, such aswalking, cycling, swimming, or more vigorous activities, such asjogging or running, resistance exercises and changes in lifestyle areessential, together with re-education of eating habits, to fight theepidemics of overweight and obesity. Besides the effect of weightcontrol, reduced body fat, prevention of weight gain and maintenanceof lean mass, physical exercise is related to a better lipid profile andreduced risk of associated diseases, such as diabetes, hypertension,metabolic syndrome, cardiovascular diseases and, consequently,lower risk of death.

    Two studies examined the effects of physical activity/exercise on physical self-perceptions, self-efficacy, body satisfaction, fitness and relationships among these variables. In study 1, 34 female undergraduates participated in a 10-week exercise/activity program. Participants were selected from existing classes forming a weight training, aerobic exercise and activity control group. Results revealed changes in physical self-perceptions, strength, and body composition over the 10-weeks. Improvements in physical self-perceptions and fitness occurred independent of exercise/activity group. Groups differed in the perceived importance attached to physical self-perceptions. Correlations among the measures revealed relationships among physical self-perceptions, body satisfaction, global self-esteem, and fitness. In study 2, we hypothesized that weight training would have a greater effect on physical self-perceptions and body image perceptions than physical education activity classes. Thirty-seven males and 28 females were selected from existing classes forming a weight training and activity group. Results revealed no significant changes in physical self-perceptions, body image, or global self-esteem over the 10-week program, while strength and physical self-efficacy improved. Correlations among measures from both studies offer preliminary support for Sonstroem and Morgan's model for the examination of self-esteem in exercise settings.

    Full Text Available Fibromyalgic syndrome is a non-inflammatory rheumatic disease which affects primarily Caucasianwomen. Fibromyalgic syndrome can be classified as primary, when there is no other associated pathology; orsecondary, when it is diagnosed related to some other pathology. The fibromyalgic patient needs to receivemultidisciplinary treatment and different areas should work together to promote the improvement of symptoms.The most common classical symptom of this disease is the chronic and diffuse pain. The specialized literaturepresents several works that point out the effects and benefits of physical exercise as a non-pharmacologicaltreatment for patients with fibromyalgic syndrome. Aerobic activity, stretching and strength training are amongthe physical exercises. Thus, this review aimed to highlight the several ways physical exercise can be useful tothe fibromyalgic patient, especially concerning the improvement of symptoms.

    Full Text Available The aim of this article is a presentation of current knowledge regarding the changes of plasma antioxidant capacity observed in response to physical exercise. Human body created the enzymatic and non-enzymatic systems, which play a protective role in the harmful impact of free radicals. Those two systems constitute what is known as the plasma total antioxidant capacity. The amount of reactive oxygen species (ROS and reactive nitrogen species (NOS in combination with oxidation processes increases in some tissues during physiological response to physical exercise. These changes are observed after single bout of exercise as well as after regular training. The response of human body to physical exercise can be analysed using various models of exercise test. Application of repeated type of exhaustion allows for characterizing the ability of human body to adjust to the increased energy loss and increased oxygen consumption. This article presents the characteristics of components of plasma antioxidant capacity, the mechanisms of free radicals production and their role in human body. It discusses also the currently used methods of detecting changes in total antioxidant capacity and its individual elements in response to single bout of exercise and regular training. It presents the review of literature about research performed in groups of both regularly training and low exercise activity individuals as well as in group of healthy subjects and patients with circulation diseases.

    Physical exercise is an important stimulus for osteoporosis prevention and treatment. However, it is not clear yet which modality would be better to stimulate bone metabolism and enhance physical function of postmenopausal women. This review paper aims to summarize and update present knowledge on the effects of different kinds of aquatic and ground physical exercises on bone metabolism and physical function of postmenopausal women. Moderate to intense exercises, performed in a high speed during short intervals of time, in water or on the ground, can be part of a program to prevent and treat postmenopausal osteoporosis. Mechanical vibration has proven to be beneficial for bone microarchitecture, improving bone density and bone strength, as well as increasing physical function. Although impact exercises are recognized as beneficial for the stimulation of bone tissue, other variables such as muscle strength, type of muscle contraction, duration and intensity of exercises are also determinants to induce changes in bone metabolism of postmenopausal women. Not only osteoanabolic exercises should be recommended; activities aimed to develop muscle strength and body balance and improve the proprioception should be encouraged to prevent falls and fractures.

    Yoga is a multifaceted spiritual tool with enhanced health and well-being as one of its positive effects. The components of yoga which are very commonly applied for health benefits are asanas (physical postures), pranayama (regulated breathing) and meditation. In the context of asanas, yoga resembles more of a physical exercise, which may lead to the perception that yoga is another kind of physical exercise. This article aims at exploring the commonalities and differences between yoga and physical exercise in terms of concepts, possible mechanisms and effectiveness for health benefits. A narrative review is undertaken based on traditional and contemporary literature for yoga, along with scientific articles available on yoga and exercise including head-to-head comparative trials with healthy volunteers and patients with various disease conditions. Physical exercises and the physical components of yoga practices have several similarities, but also important differences. Evidence suggests that yoga interventions appear to be equal and/or superior to exercise in most outcome measures. Emphasis on breath regulation, mindfulness during practice, and importance given to maintenance of postures are some of the elements which differentiate yoga practices from physical exercises.

    Objectives: When physical exercise is systematically coupled to music production, exercisers experience improvements in mood, reductions in perceived effort, and enhanced muscular efficiency. The physiology underlying these positive effects remains unknown. Here we approached the investigation of how such musical agency may stimulate the release of endogenous opioids indirectly with a pain threshold paradigm. Design: In a cross-over design we tested the opioid-hypothesis with an indirect measure, comparing the pain tolerance of 22 participants following exercise with or without musical agency. Method: Physical exercise was coupled to music by integrating weight-training machines with sensors that control music-synthesis in real time. Pain tolerance was measured as withdrawal time in a cold pressor test. Results: On average, participants tolerated cold pain for ~5 s longer following exercise sessions with musical agency. Musical agency explained 25% of the variance in cold pressor test withdrawal times after factoring out individual differences in general pain sensitivity. Conclusions: This result demonstrates a substantial pain reducing effect of musical agency in combination with physical exercise, probably due to stimulation of endogenous opioid mechanisms. This has implications for exercise endurance, both in sports and a multitude of rehabilitative therapies in which physical exercise is effective but painful.

    Full Text Available The present study has as objective investigates the prescription of exercises for elderly, constant in the literature in portuguese language, under form of books, newspapers, annals and publications electronics. For so much, it tried to collect data with relationship to the following aspects: a Impact of the aging in the human organism; b evaluation of the components of the functional aptitude; and, c composition of a program of physical exercise. The aging process evidences changes in the levels antropométrics, neuromuscular, cardiovascular, lung, neural, besides the decrease of the agility, coordination, balance, flexibility, mobility to articulate and increase in the cartilage rigidity, tendons and ligaments. Those changes associated to the low level of physical activity in the elderly take to the decline of the functional capacity. The evaluation of the level of functional dependence becomes important to the elderly, because it will provide a prescription of physical exercises more addressed your needs, increasing the effectiveness of the program and reducing the risks. The general beginnings for the prescription of physical exercises for elderly are based in the modalities appropriate, intensity, duration, frequency and progression of the physical activity, with the objective of improving the life quality, to minimize the physiologic alterations, to improve the motive capacity and to provide benefits social, psychological and physical. Therefore, in the prescription of physical exercises for older people is necessary the training of the capacity aerobics, of the force, of the balance, of the time of reaction and movement and of the agility.

  15. Physical exercise in type 1 diabetes: recommendations and care

    Directory of Open Access Journals (Sweden)

    Luis Paulo Gomes Mascarenhas

    Full Text Available Abstract The management of type 1 diabetes mellitus (T1DM is based on three pillars: insulin therapy, nutrition, and regular practice of physical activity. Physical exercises are associated with metabolic demands that depend on the individual's energy stores and level of physical conditioning, and vary according to environmental conditions and intensity, duration, and type of exercise. All these factors, added to eventual distress with competitions, exert influence on glucose metabolism. The athletic career of diabetic individuals is often hindered by a risk of hypoglycemia during and after the exercise, frequent hyperglycemia before, during, and after certain physical activities, occurrence of ketoacidosis, and presence of chronic microvascular and macrovascular complications. Aerobic exercises reduce the levels of blood glucose while anaerobic exercise may promote transient hyperglycemia. Although diabetic individuals may achieve excellence in sport, their physical performance should be maximized by strict blood glucose control, adequate modifications in insulin dose on the day of the exercise, and appropriate nutritional intake. This review discusses the impact of physical exercise on glucose metabolism, as well as nutritional considerations and strategies appropriate to the practice of physical exercises by patients with T1DM.

    High blood pressure is a frequent pathology with many cardiovascular complications. As highlighted in guidelines, the therapeutic management of hypertension relies on non-pharmacological measures, which are diet and regular physical activity, but both patients and physicians are reluctant to physical activity prescription. To acquire the conviction that physical activity is beneficial, necessary and possible, we can take into account some fundamental and clinical studies, as well as the feedback of our clinical practice. Physical inactivity is a major risk factor for cardiovascular morbidity and mortality, and hypertension contributes to increase this risk. Conversely, regular practice of physical activity decreases very significantly the risk by up to 60%. The acute blood pressure changes during exercise and post-exercise hypotension differs according to the dynamic component (endurance or aerobic and/or strength exercises), but the repetition of the sessions leads to the chronic hypotensive benefit of physical activity. Moreover, physical activity prescription must take into account the assessment of global cardiovascular risk, the control of the hypertension, and the opportunities and desires of the patient in order to promote good adherence and beneficial lifestyle change.

  20. Do placebo expectations influence perceived exertion during physical exercise?

    Directory of Open Access Journals (Sweden)

    Hendrik Mothes

    Full Text Available This study investigates the role of placebo expectations in individuals' perception of exertion during acute physical exercise. Building upon findings from placebo and marketing research, we examined how perceived exertion is affected by expectations regarding a the effects of exercise and b the effects of the exercise product worn during the exercise. We also investigated whether these effects are moderated by physical self-concept. Seventy-eight participants conducted a moderate 30 min cycling exercise on an ergometer, with perceived exertion (RPE measured every 5 minutes. Beforehand, each participant was randomly assigned to 1 of 4 conditions and watched a corresponding film clip presenting "scientific evidence" that the exercise would or would not result in health benefits and that the exercise product they were wearing (compression garment would additionally enhance exercise benefits or would only be worn for control purposes. Participants' physical self-concept was assessed via questionnaire. Results partially demonstrated that participants with more positive expectations experienced reduced perceived exertion during the exercise. Furthermore, our results indicate a moderator effect of physical self-concept: Individuals with a high physical self-concept benefited (in terms of reduced perceived exertion levels in particular from an induction of generally positive expectations. In contrast, individuals with a low physical self-concept benefited when positive expectations were related to the exercise product they were wearing. In sum, these results suggest that placebo expectations may be a further, previously neglected class of psychological factors that influence the perception of exertion.

    [Purpose] The intensity of therapeutic physical exercise is complex and sometimes controversial in patients with neural injuries. This review assessed whether therapeutic physical exercise is beneficial according to the intensity of the physical exercise. [Methods] The authors identified clinically or scientifically relevant articles from PubMed that met the inclusion criteria. [Results] Exercise training can improve body strength and lead to the physiological adaptation of skeletal muscles and the nervous system after neural injuries. Furthermore, neurophysiological and neuropathological studies show differences in the beneficial effects of forced therapeutic exercise in patients with severe or mild neural injuries. Forced exercise alters the distribution of muscle fiber types in patients with neural injuries. Based on several animal studies, forced exercise may promote functional recovery following cerebral ischemia via signaling molecules in ischemic brain regions. [Conclusions] This review describes several types of therapeutic forced exercise and the controversy regarding the therapeutic effects in experimental animals versus humans with neural injuries. This review also provides a therapeutic strategy for physical therapists that grades the intensity of forced exercise according to the level of neural injury.

  2. Accuracy of physical self-description among chronic exercisers and non-exercisers

    2014-10-01

    Full Text Available This study addressed the role of chronic exercise to enhance physical self-description as measured by self-estimated percent body fat. Accuracy of physical self-description was determined in normal-weight, regularly exercising and non-exercising males with similar body mass index (BMI’s and females with similar BMI’s (n=42 males and 45 females of which 23 males and 23 females met criteria to be considered chronic exercisers. Statistical analyses were conducted to determine the degree of agreement between self-estimated percent body fat and actual laboratory measurements (hydrostatic weighing. Three statistical techniques were employed: Pearson correlation coefficients, Bland and Altman plots, and regression analysis. Agreement between measured and self-estimated percent body fat was superior for males and females who exercised chronically, compared to non-exercisers. The clinical implications are as follows. Satisfaction with one’s body can be influenced by several factors, including self-perceived body composition. Dissatisfaction can contribute to maladaptive and destructive weight management behaviors. The present study suggests that regular exercise provides a basis for more positive weight management behaviors by enhancing the accuracy of self-assessed body composition.

    Affective responses during exercise are often important determinants of exercise initiation and maintenance. Current physical activity may be one individual difference that is associated with the degree to which individuals have positive (or negative) affective experiences during exercise. The objective of this study was to explore physical and cognitive explanations of the relationship between current activity status (more versus less active) and affective response during a 30-minute bout of moderate-intensity exercise. Participants reported their current level of physical activity, exercise self-efficacy and affect during a 30-minute bout of moderate-intensity exercise. More active individuals experienced higher levels of positive affect and tranquillity and lower levels of negative affect and fatigue during exercise. Multivariate models for each affective state indicated separate processes through which physical activity may be associated with changes in affect during exercise. These models indicate that affect experienced during physical activity is related to the current activity level and these relationships can be partially explained by the physical and cognitive factors explored in this study. Recommendations for future research to elucidate whether positive affective response to physical activity improves as a function of becoming more active over time are discussed.

    Physical exercise training may form an important part of regular care for people with cystic fibrosis. This is an update of a previously published review. To assess the effects of physical exercise training on exercise capacity by peak oxygen consumption, pulmonary function by forced expiratory volume in one second, health-related quality of life and further important patient-relevant outcomes in people with cystic fibrosis. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of the most recent search: 04 May 2017.We searched ongoing trials registers (clinicaltrials.gov and the WHO ICTRP). Date of most recent search: 10 August 2017. All randomised and quasi-randomised controlled clinical trials comparing exercise training of any type and a minimum duration of two weeks with conventional care (no training) in people with cystic fibrosis. Two authors independently selected studies for inclusion, assessed methodological quality and extracted data. The quality of the evidence was assessed using the GRADE system. Of the 83 studies identified, 15 studies which included 487 participants, met the inclusion criteria. The numbers in each study ranged from nine up to 72 participants; two studies were in adults, seven were in children and adolescents and six studies included all age ranges. Four studies of hospitalised participants lasted less than one month and 11 studies were outpatient-based, lasting between two months and three years. The studies included participants with a wide range of disease severity and employed differing levels of supervision with a mixture of types of training. There was also wide variation in the quality of the included studies.This systematic review shows very low- to low-quality evidence from both short- and long-term studies that in people

    Full Text Available Objective: Investigating and comparing the effects of exercise and physical therapy accompanying exercise treatments in patients with chronic low back pain. Materials and Methods: Twenty three patients with mechanical type low back existing more than 3 months were included one of the exercise or the physical therapy+exercise groups according to their application sequence. Both of the groups performed lumbar flexion and extension exercises, strengthening of the lumbar and abdominal muscle exercises and iliopsoas, hamstring and quadriceps stretching exercises two times a day for 14 days. The physical therapy group was given hot pack+therapeutic ultrasound+ interferential current for 10 days additionally. Degree of the low back pain was evaluated with visual analog scale (VAS, range of joint motion was evaluated with hand finger floor distance (HFFD and Modified Schober test, functional status was evaluated with Modified Oswestry Low Back Pain Scale and quality of life was evaluated with Short form-36 (SF-36 before and a month after the treatments. Results: In both groups (exercise group: average age 59 years, 21 females, 2 males; physical therapy group: average age 60 years, 20 females, 3 males pain intensity and HFFD decreased and Modified Schober increased, functionality recovered, pain and physical functions of SF-36 improved after the treatments. SF-36-physical role difficulty also improved in the exercise group. Decrease in pain, increase in HFFD andimproving of the functional status were all significantly more in the physical therapy group. There were no difference between the groups in terms of Modified Schober measurement and changes of the quality of life. Conclusions: Exercises and exercise+physical therapy are both effective in chronic low back pain. Successful results can be taken by addition of the physical therapy in patients who do not benefit sufficiently from exercise therapy. (Turkish Journal of Osteoporosis 2015;21: 73-8

    2015-01-01

    Laboratory exercises are an important part of general Physics teaching, both during the last years of high school and the first year of college education. Due to the need to acquire enough laboratory equipment for all the students, and the widespread access to computers rooms in teaching, we propose the development of computer simulated laboratory exercises. A representative exercise in general Physics is the calculation of the gravity acceleration value, through the free fall motion of a metal ball. Using a model of the real exercise, we have developed an interactive system which allows students to alter the starting height of the ball to obtain different fall times. The simulation was programmed in ActionScript 3, so that it can be freely executed in any operative system; to ensure the accuracy of the calculations, all the input parameters of the simulations were modelled using digital measurement units, and to allow a statistical management of the resulting data, measurement errors are simulated through limited randomization

    2006-04-01

    One of the major symptoms of chronic fatigue syndrome (CFS) is reduced exercise and functional capacity and increased fatigue symptoms following physical effort. A review of the literature indicates that patients that suffer from CFS are characterized by: low aerobic capacity, higher heart rate during sub-maximal exercise, higher subjective effort prescription, reduced muscle strength, and prolonged recovery period. Although several symptoms are a result of lack of physical activity, several mechanisms were suggested to explain those symptoms: pathological heart rate control, reduced aerobic metabolic capacity, reduced blood supply to the working muscles and nerve system dysfunction. Participating in guided exercise programs was found to be the most effective treatment in improving exercise and functional capacity, reducing fatigue syndromes and improving patients' daily function.

    Full Text Available Neva J Kirk-Sanchez,1 Ellen L McGough21Department of Physical Therapy, University of Miami Miller School of Medicine, Miami, FL, USA; 2Department of Rehabilitation Medicine, University of Washington, Seattle, WA, USAAbstract: In an aging population with increasing incidence of dementia and cognitive impairment, strategies are needed to slow age-related decline and reduce disease-related cognitive impairment in older adults. Physical exercise that targets modifiable risk factors and neuroprotective mechanisms may reduce declines in cognitive performance attributed to the normal aging process and protect against changes related to neurodegenerative diseases such as Alzheimer's disease and other types of dementia. In this review we summarize the role of exercise in neuroprotection and cognitive performance, and provide information related to implementation of physical exercise programs for older adults. Evidence from both animal and human studies supports the role of physical exercise in modifying metabolic, structural, and functional dimensions of the brain and preserving cognitive performance in older adults. The results of observational studies support a dose-dependent neuroprotective relationship between physical exercise and cognitive performance in older adults. Although some clinical trials of exercise interventions demonstrate positive effects of exercise on cognitive performance, other trials show minimal to no effect. Although further research is needed, physical exercise interventions aimed at improving brain health through neuroprotective mechanisms show promise for preserving cognitive performance. Exercise programs that are structured, individualized, higher intensity, longer duration, and multicomponent show promise for preserving cognitive performance in older adults.Keywords: aging, neurodegeneration, dementia, brain, physical activity

    Appropriate physical activity is one of the bases of healthy lifestyle. In fact, physical exercise and playing sport may be associated with both improvements and injury to both general and reproductive health. A biologically normal testosterone secretion appears fundamental in males to guarantee both a physiological exercise adaptation and safe sport participation. The reproductive system is highly sensitive to the effects of exercise-related stress and the reproductive hormones may both increase and decrease after different acute or chronic exercises. Exercise and sport participation may positively or negatively influence andrological health status depending on the type, intensity and duration of performed physical activity and on individual health status. In addition, prohibited substances administration (e.g. androgenic-anabolic steroids, and so forth) in competitive and non-competitive athletes represents the main cause of iatrogenic andrological diseases. Preventing and treating andrological problems in active healthy and unhealthy individuals is as important as promoting a correct lifestyle. Physicians need to be educated on the relationships between the male reproductive system and sport participation and on the great role of the pre-participation physical examination in the prevention of andrological diseases.

    The purpose of this study was to investigate the importance of enjoyment of exercise in a health care-based intervention aimed at promoting physical exercise in primary health care patients. In a controlled study design, the intervention group was offered a wide range of group exercises over 3 months, followed by support in designing their own exercise program. The control group received usual care. Enjoyment of exercise and exercise level were measured. Associations between enjoyment and exercise level were analyzed using Spearman's rank correlation coefficients. Changes in enjoyment between and within study groups were analyzed by the independent and paired t-test. Associations were found between enjoyment and exercise level (r=0.36, Pexercise level (r=0.34, Pexercise was 25% higher in the intervention group than in the control group (Phealth care patients, enjoyment of exercise was associated with exercise level. Enjoyment of exercise seems to be a mediator of exercise level. Furthermore, health care-based interventions seem to be able to affect enjoyment of exercise. Enjoyment of exercise may be important for the long-term effectiveness, of health care-based interventions.

    Physical activity/exercise is regarded as an important self-management strategy for individuals with mental illness. The purpose of this study was to describe individuals with mood and/or anxiety disorders who were exercising or engaging in physical activity to help manage their disorders versus those who were not, and the facilitators for and barriers to engaging in physical activity/exercise. For this study, we used data from the 2014 Survey on Living with Chronic Diseases in Canada-Mood and Anxiety Disorders Component. Selected respondents (n = 2678) were classified according to the frequency with which they exercised: (1) did not exercise; (2) exercised 1 to 3 times a week; or (3) exercised 4 or more times a week. We performed descriptive and multinomial multiple logistic regression analyses. Estimates were weighted to represent the Canadian adult household population living in the 10 provinces with diagnosed mood and/or anxiety disorders. While 51.0% of the Canadians affected were not exercising to help manage their mood and/or anxiety disorders, 23.8% were exercising from 1 to 3 times a week, and 25.3% were exercising 4 or more times a week. Increasing age and decreasing levels of education and household income adequacy were associated with increasing prevalence of physical inactivity. Individuals with a mood disorder (with or without anxiety) and those with physical comorbidities were less likely to exercise regularly. The most important factor associated with engaging in physical activity/exercise was to have received advice to do so by a physician or other health professional. The most frequently cited barriers for not exercising at least once a week were as follows: prevented by physical condition (27.3%), time constraints/too busy (24.1%) and lack of will power/self-discipline (15.8%).

  4. Mastery-style exercises in physics

    Science.gov (United States)

    Schroeder, Noah D.

    Mastery learning employs repeated cycles of instructional support and formative assessment to help students achieve desired skills. Instructional objectives are broken into small pieces, and students master those pieces in successive order by performing to a set standard on an assessment for each objective. If a student cannot master an objective, instructional support is provided, and the student is reassessed. Mastery learning has been proved effective in many subject areas, but comparatively little research has been done on applying it in physics instruction. This dissertation details the path taken that culminated in the use of mastery-inspired exercises to teach students basic skills in introductory physics courses. The path that led to our choice of mastery began with an attempt to provide students with extra practice and formative assessment through weekly practice tests with corresponding solutions, with the goal of helping them better prepare for summative exams in an introductory physics course. No effect was seen, and participation was very low. Investigating how students learn from solutions revealed that they are poor evaluators of their understanding of provided solutions and struggle to retain the skills taught in those solutions. In a follow-up clinical experiment that provided students with solutions, required them to recall the solutions from memory, and re-presented the solutions for restudy, students showed strong retention as well as the ability to transfer information from the solutions to new situations. These results inspired the formal use of mastery learning as an instructional paradigm due to its requirement that students repeatedly recall information from solutions and apply it to new situations. Mastery-style exercises were first created and tested in clinical trials, followed by two in-course implementations. In the clinical trials, students completed a set of questions on a particular skill, and if they failed to master that skill

    Full Text Available College students’ consciousness of physical exercise is so weak in recent years. The exercising habit is hard to form and physique conditions decline year by year. Combining practical teaching experience and considering influencing factors of college students, the author carries out an investigation and a statistical analysis on the college students’ participation of physical exercise through methods of documents, questionnaire survey and mathematical statistics according to personalities of college students. The result indicates that the lack of fields and facilities, the lack of leisure time, the lack of companions, the lack of sport specialties and the lack of teachers’ guidance and extracurricular sports competitions are major factors influencing physical exercise of college students. So, how to form the habit of college students participating in physical exercise should be reexamined so as to form the consciousness of lifelong physical exercise. A more particular knowledge of college students’ awareness and needs of physical exercise provide references for sports work of colleges and universi-ties, provide theoretical and practical supports for college students participating in physical exercise, and promote college students’ development of qualities from all aspects.

We used the leisure time exercise questionnaire to assess the frequency and intensity of exercise. The planned behavior scale examined seven factors affecting physical activity: attitude, intention, self-identity, attitude strength, social role model, information, and knowledge.Results: Asthmatic children did not differ significantly in mild, moderate, and overall level of physical activity from children without asthma but they participated less in intense and systematic exercise. The two asthmatic groups did not differ in any of the planned behavior factors. Significant differences between genders occurred with respect to self-identity and social role model. Boys appeared to exercise more regularly and intensely compared to girls.Conclusion: Asthmatic children did not systematically participate in physical activity, preferring mostly mild and moderate intensity activities. Children with and without asthma had comparable positive attitudes and intentions toward exercise.Keywords: planned behavior theory, asthma, sports, health behavior

  8. Talking to patients with fibromyalgia about physical activity and exercise.

    2008-03-01

    The purpose of this article is to describe the application of basic exercise principles to individuals with fibromyalgia to encourage clinicians to discuss with their patients ways of becoming more physically active. The goals of increased physical activity and exercise for individuals with fibromyalgia are to improve or maintain general fitness, physical function, emotional well being, symptoms and overall health, and provide them with a feeling of control over their well being. Describing ways of increasing activity through home, work and leisure-related tasks or exercise provides a universal approach to increasing physical activity that applies to individuals with fibromyalgia and fits a counseling model of health behavior familiar to clinicians. The patient-clinician relationship provides a unique opportunity for health professionals to counsel individuals with fibromyalgia to become and remain more physically active. Regular physical activity and exercise has numerous physical, psychological, and functional benefits for individuals with fibromyalgia and should be included in treatment plans. Clinicians can help patients adopt a more physically active lifestyle through targeted discussions, support and consistent follow up.

    Previous studies have separately reported the effects of physical exercise and yoga in children, showing physical, cognitive and emotional benefits. The present randomized controlled trial assessed the effects of yoga or physical exercise on physical fitness, cognitive performance, self-esteem, and teacher-rated behavior and performance, in school children. 98 school children between 8 to 13 years were randomized as yoga and physical exercise groups {n = 49 each; (yoga: 15 girls, group mean age 10.4 ± 1.2 years), (physical exercise: 23 girls, group mean age 10.5 ± 1.3 years)}. Both groups were blind assessed after allocation, using: (i) the Eurofit physical fitness test battery, (ii) Stroop color-word task for children, (iii) Battle's self-esteem inventory and (iv) the teachers' rating of the children's obedience, academic performance, attention, punctuality, and behavior with friends and teachers. After assessments the yoga group practiced yoga (breathing techniques, postures, guided relaxation and chanting), 45 minutes each day, 5 days a week. During this time the physical exercise group had jogging-in-place, rapid repetitive movements and relay races or games. Both groups were assessed at the end of 3 months. Data were analyzed with RM ANOVA and post-hoc tests were Bonferroni adjusted. There was one significant difference between groups. This was in social self-esteem which was higher after physical exercise compared to yoga (p exercise group, while plate tapping improved in the yoga group (p exercise group showed higher interference scores.

    This book presents exercises and problems in the mathematical methods of physics with the aim of offering undergraduate students an alternative way to explore and fully understand the mathematical notions on which modern physics is based. The exercises and problems are proposed not in a random order but rather in a sequence that maximizes their educational value. Each section and subsection starts with exercises based on first definitions, followed by groups of problems devoted to intermediate and, subsequently, more elaborate situations. Some of the problems are unavoidably "routine", but others bring to the forenontrivial properties that are often omitted or barely mentioned in textbooks. There are also problems where the reader is guided to obtain important results that are usually stated in textbooks without complete proofs. In all, some 350 solved problems covering all mathematical notions useful to physics are included. While the book is intended primarily for undergraduate students of physics, students...

  13. The impact of exercise performance dissatisfaction and physical exercise on symptoms of depression among college students: a gender comparison.

    Edman, Jeanne L; Lynch, Wesley C; Yates, Alayne

    2014-01-01

    Depression is a common psychological problem and females have been found to be at greater risk for this disorder than males. Although numerous studies have found that physical exercise is negatively associated with risk of depression, some studies suggest that negative exercise attitudes may increase the risk of depression. The present study used the survey method to examine the relationship between depressive symptoms, exercise performance dissatisfaction, body dissatisfaction, and physical exercise among a sample of 895 undergraduate university students. Females reported higher depression and exercise performance dissatisfaction scores than males; however, there were no gender differences in body dissatisfaction. Exercise performance dissatisfaction was positively associated with depression among both males and females. Physical exercise was negatively associated with depression among males, but not among females. The possibility of screening participants enrolled in exercise programs for performance dissatisfaction is discussed as negative exercise attitudes may diminish the positive impact of exercise on depressed mood.

    While benefits of workplace physical exercise on physical health is well known, little is known about the psychosocial effects of such initiatives. This study evaluates the effect of workplace versus home-based physical exercise on psychosocial factors among healthcare workers. A total of 200 female healthcare workers (Age: 42.0, BMI: 24.1) from 18 departments at three hospitals were cluster-randomized to 10 weeks of: 1) home-based physical exercise (HOME) performed alone during leisure time for 10 min 5 days per week or 2) workplace physical exercise (WORK) performed in groups during working hours for 10 min 5 days per week and up to 5 group-based coaching sessions on motivation for regular physical exercise. Vitality and mental health (SF-36, scale 0-100), psychosocial work environment (COPSOQ, scale 0-100), work- and leisure disability (DASH, 0-100), control- (Bournemouth, scale 0-10) and concern about pain (Pain Catastrophizing Scale, scale 0-10) were assessed at baseline and at 10-week follow-up. Vitality as well as control and concern about pain improved more following WORK than HOME (all p health remained unchanged. Between-group differences at follow-up (WORK vs. HOME) were 7 [95% confidence interval (95% CI) 3 to 10] for vitality, -0.8 [95% CI -1.3 to -0.3] for control of pain and -0.9 [95% CI -1.4 to -0.5] for concern about pain, respectively. Performing physical exercise together with colleagues during working hours was more effective than home-based exercise in improving vitality and concern and control of pain among healthcare workers. These benefits occurred in spite of increased work pace. NCT01921764 at ClinicalTrials.gov . Registered 10 August 2013.

    Korsager Larsen, Monica; Matchkov, Vladimir V

    2016-01-01

    Oxidative stress is associated with the pathogenesis of hypertension. Decreased bioavailability of nitric oxide (NO) is one of the mechanisms involved in the pathogenesis. It has been suggested that physical exercise could be a potential non-pharmacological strategy in treatment of hypertension because of its beneficial effects on oxidative stress and endothelial function. The aim of this review is to investigate the effect of oxidative stress in relation to hypertension and physical exercise, including the role of NO in the pathogenesis of hypertension. Endothelial dysfunction and decreased NO levels have been found to have the adverse effects in the correlation between oxidative stress and hypertension. Most of the previous studies found that aerobic exercise significantly decreased blood pressure and oxidative stress in hypertensive subjects, but the intense aerobic exercise can also injure endothelial cells. Isometric exercise decreases normally only systolic blood pressure. An alternative exercise, Tai chi significantly decreases blood pressure and oxidative stress in normotensive elderly, but the effect in hypertensive subjects has not yet been studied. Physical exercise and especially aerobic training can be suggested as an effective intervention in the prevention and treatment of hypertension and cardiovascular disease via reduction in oxidative stress.

    To determine the intensity and volume of therapeutic exercises during a standard 13-day inpatient neck rehabilitation course in relation to overall physical activity in rehabilitation and everyday life. Cross-sectional study. Subjects (n = 19; 16 women and 3 men; mean age 48.6 years, standard deviation (SD) 6.6) with chronic non-specific neck pain were recruited from two inpatient neck rehabilitation courses. Intensity and volume of therapeutic exercises and physical activity were measured in metabolic equivalents (METs) with an objective measurement device and all-time recall questionnaire. Maximum oxygen uptake was determined in METs (METc) by direct maximal cycle ergometer. Subjects' mean METc was 7.2 METs (SD 1.4) or 25.3 ml/kg/min (SD 4.8). Intensity of all therapeutic exercises was 1.9 METs or 27 %METc (SD 5.1) and volume 7.7 MET-hours/week. Intensity of specific neck and shoulder exercises was 2.0 METs or 28 %METc (SD 5.4) and volume 2.5 MET-hours/week. In addition, subjects were more active in everyday life than in inpatient rehabilitation. The therapeutic exercise dose failed to reach previously reported target values for pain relief. The dose of therapeutic exercises and confounding physical activity should be carefully controlled in pain rehabilitation programmes.

    The efficacy of physical exercise for the prevention and treatment of non-specific low back pain (LBP) is well documented, but little is known about how individuals value specific components of physical exercise, such as the type and design or the intensity and frequency of exercise. Other factors that influence individual differences in health choices and adherence are associated with individuals' attitudes toward and likelihood of performing recommended exercise regimens. Current evidence shows that efficacy is similar among exercise interventions, but their features vary widely. Thus it may be difficult for clinicians to discriminate between available options in clinical practice. Considering the many challenges in determining the form of exercise best suited to the individual patient, this commentary discusses some of the practical methods that could be used to elicit individual preference for recommended health care interventions. Such methods have the advantage of providing more information for health care decision making, particularly with regard to exercise interventions for LBP. This commentary also advocates for the use of patient preference in health care decisions.

    2012-01-01

    Background Motivation is a critical factor in supporting sustained exercise, which in turn is associated with important health outcomes. Accordingly, research on exercise motivation from the perspective of self-determination theory (SDT) has grown considerably in recent years. Previous reviews have been mostly narrative and theoretical. Aiming at a more comprehensive review of empirical data, this article examines the empirical literature on the relations between key SDT-based constructs and exercise and physical activity behavioral outcomes. Methods This systematic review includes 66 empirical studies published up to June 2011, including experimental, cross-sectional, and prospective studies that have measured exercise causality orientations, autonomy/need support and need satisfaction, exercise motives (or goal contents), and exercise self-regulations and motivation. We also studied SDT-based interventions aimed at increasing exercise behavior. In all studies, actual or self-reported exercise/physical activity, including attendance, was analyzed as the dependent variable. Findings are summarized based on quantitative analysis of the evidence. Results The results show consistent support for a positive relation between more autonomous forms of motivation and exercise, with a trend towards identified regulation predicting initial/short-term adoption more strongly than intrinsic motivation, and intrinsic motivation being more predictive of long-term exercise adherence. The literature is also consistent in that competence satisfaction and more intrinsic motives positively predict exercise participation across a range of samples and settings. Mixed evidence was found concerning the role of other types of motives (e.g., health/fitness and body-related), and also the specific nature and consequences of introjected regulation. The majority of studies have employed descriptive (i.e., non-experimental) designs but similar results are found across cross

    Full Text Available Large and consistent beneficial effects with few adverse effects have been found in relation to physical exercise in selected samples of elderly subjects. However, thus far, it has not been confirmed to what extent the effects of physical exercise among elderly people are beneficial or even harmful in population-based studies. Additionally, the role of exercise testing among elderly people remains unclear. Firstly, the effects of prolonged physical training on cardiovascular fitness in 66-85-year-old women were examined in a cross-sectional study. Secondly, the predictive value of exercise-test status and results, including exercise capacity for survival, were studied in 75-year-old men and women. Thirdly, the effects of an endurance and strength training programme were examined in women aged 76 to 78 years in a population-based randomized controlled trial. Finally, the cardiac-adverse effects of acute exercise in the form of a cycle ergometer test were clarified in 75-year-old men and women. In the maximal exercise tests the mean peak oxygen uptake was respectively 26.2 and 18.7 ml·kg-1·min-1 among the physically active and less active control women. High cycling power (Watts per kg body weight in the completed ergometer test was associated with decreased risk for death (multivariate HR 0.20; CI 0.08 - 0.50. The 18-week strength training resulted in a 9.4% increase in peak oxygen uptake while the endurance training improved peak oxygen uptake by 6.8%. A significant increase in cycling power in W/kg was found in the strength and endurance training groups compared to controls. Five cases of cardio- or cerebrovascular health problems emerged in the exercise training groups. These health problems were not directly related to physical exertion. In the final study 23 and 7% of the exercise tests in men and women, respectively, were prematurely terminated because of cardiac arrhythmia or ST segment depressions.

    Aerobic exercises to music can have a positive effect on functional and motor skills of an exerciser, their health, as well as an aesthetic and socio-psychological component. The objective of this study was to determine the effects of reactive exercising in a group on functional capabilities in physically active and physically inactive women. A prospective study included 64 healthy women aged 40-60 years. The sample was divided into the experimental group (n= 36), i.e. physically active women who have been engaged in recreational group exercises at the Faculty of Sport and Physical Education, University of Novi Sad, Serbia, and the control group (n= 28), which consisted of physically inactive women. All the participants were monitored using the same protocol before and after the implementation of the research. All women had their height, weight, body mass index measured as well as spiroergometric parameters determined according to the Bruce protocol. A univariate analysis of variance has shown that there is a statistically significant difference between the experimental group and the control group in maximum speed, the total duration of the test, relative oxygen consumption, absolute oxygen consumption and ventilation during the final measurement. After the training intervention, the experimental group showed improvements in all the parameters analyzed compared with pretest values. The recreational group exercise model significantly improves aerobic capacity and functioning of the cardiovascular system. Therefore, it is essential for women to be involved more in any form of recreational group exercising in order to improve functional capacity and health.

  14. Protein S100B and physical exercise

    2010-01-01

    Full Text Available Protein S100B has been used as a peripheral biochemical marker of brain injury and/or activity. However, recent studies have demonstrated that this protein is also increased in serum after physical exercise, although the interpretation of this finding remains controversial. Although predominantly released by astrocytes in the central nervous system, extracerebral sources of protein S100B have been suggested to contribute to the increase in serum levels of this protein. However, in the case of exercises that have an impact on the brain such as boxing, elevated levels are clearly associated with brain damage. More recently, some studies have proposed that protein S100B might be released by activated adipocytes and by damaged muscle cells. If confirmed experimentally, protein S100B might be potentially useful in sports training. We are currently investigating the potential role of serum protein S100B as an indicator of muscle damage. Therefore, the objective of this review was to discuss the current knowledge about the relationship between physical exercise and serum protein S100B and its possible leakage from muscle cells injured by exercise.

    This study aimed to assess the effect of two sessions of acute physical exercise at 50% VO2peak performed under hypoxia (equivalent to an altitude of 4500 m for 28 h) on sleep, mood and reaction time. Forty healthy men were randomized into 4 groups: Normoxia (NG) (n = 10); Hypoxia (HG) (n = 10); Exercise under Normoxia (ENG) (n = 10); and Exercise under Hypoxia (EHG) (n = 10). All mood and reaction time assessments were performed 40 min after awakening. Sleep was reassessed on the first day at 14 h after the initiation of hypoxia; mood and reaction time were measured 28 h later. Two sessions of acute physical exercise at 50% VO2peak were performed for 60 min on the first and second days after 3 and 27 h, respectively, after starting to hypoxia. Improved sleep efficiency, stage N3 and REM sleep and reduced wake after sleep onset were observed under hypoxia after acute physical exercise. Tension, anger, depressed mood, vigor and reaction time scores improved after exercise under hypoxia. We conclude that hypoxia impairs sleep, reaction time and mood. Acute physical exercise at 50% VO2peak under hypoxia improves sleep efficiency, reversing the aspects that had been adversely affected under hypoxia, possibly contributing to improved mood and reaction time.

    Given the evidence that regular physical activity produces substantial health benefits, participation in sports, exercise, and recreation is widely encouraged. The objective of this study was to describe participation in sports, exercise, and recreational physical activities among US adults. Data from 2 national surveys of respondents age 18 years and older were analyzed. Respondents to the American Time Use Survey (ATUS) from 2003 through 2005 (N=45,246) reported all activities on 1 randomly selected survey day. Respondents to the National Health and Nutrition Examination Survey (NHANES) from 1999 through 2004 (N=17,061) reported leisure-time physical activities in the 30 days before the interview. One-quarter of adults participated in any sport, exercise, or recreational activity on a random day, and 60.9% of adults participated in any leisure-time activity in the previous 30 days. The most common types of activities were walking, gardening and yard work, and other forms of exercise. The sports and recreational activities had typical durations of 1/2 to 3 hours per session, and the exercise activities typically lasted 1 hour or less. The prevalence of sports, exercise, and recreational physical activities is generally low among US adults; exercise is the most commonly reported type of activity.

    2005-03-01

    This review highlights recent work evaluating the relationship between exercise, physical activity and physical and mental health. Both cross-sectional and longitudinal studies, as well as randomized clinical trials, are included. Special attention is given to physical conditions, including obesity, cancer, cardiovascular disease and sexual dysfunction. Furthermore, studies relating physical activity to depression and other mood states are reviewed. The studies include diverse ethnic populations, including men and women, as well as several age groups (e.g. adolescents, middle-aged and older adults). Results of the studies continue to support a growing literature suggesting that exercise, physical activity and physical-activity interventions have beneficial effects across several physical and mental-health outcomes. Generally, participants engaging in regular physical activity display more desirable health outcomes across a variety of physical conditions. Similarly, participants in randomized clinical trials of physical-activity interventions show better health outcomes, including better general and health-related quality of life, better functional capacity and better mood states. The studies have several implications for clinical practice and research. Most work suggests that exercise and physical activity are associated with better quality of life and health outcomes. Therefore, assessment and promotion of exercise and physical activity may be beneficial in achieving desired benefits across several populations. Several limitations were noted, particularly in research involving randomized clinical trials. These trials tend to involve limited sample sizes with short follow-up periods, thus limiting the clinical implications of the benefits associated with physical activity.

    Although people with haematological malignancies have to endure long phases of therapy and immobility which is known to diminish their physical performance level, the advice to rest and avoid intensive exercises is still common practice. This recommendation is partly due to the severe anaemia and thrombocytopenia from which many patients suffer. The inability to perform activities of daily living restricts them, diminishes their quality of life and can influence medical therapy. To evaluate the efficacy, safety and feasibility of aerobic physical exercise for adults suffering from haematological malignancies. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2014, Issue 1) and MEDLINE (1950 to January 2014) as well as conference proceedings for randomised controlled trials (RCTs). We included RCTs comparing an aerobic physical exercise intervention, intending to improve the oxygen system, in addition to standard care with standard care only for adults suffering from haematological malignancies. We also included studies that evaluated aerobic exercise in addition to strength training. We excluded studies that investigated the effect of training programmes that were composed of yoga, tai chi chuan, qigong or similar types of exercise. We also excluded studies exploring the influence of strength training without additive aerobic exercise. Additionally, we excluded studies assessing outcomes without any clinical impact. Two review authors independently screened search results, extracted data and assessed the quality of trials. We used risk ratios (RRs) for adverse events and 100-day survival, standardised mean differences for quality of life (QoL), fatigue, and physical performance, and mean differences for anthropometric measurements. Our search strategies identified 1518 potentially relevant references. Of these, we included nine RCTs involving 818 participants. The potential risk of bias in these trials is unclear, due

    To investigate physical activity levels of nursing and medicine students, examine predictors of physical activity level and examine the most influential benefits and barriers to exercise. Healthcare professionals have low levels of physical activity, which increases their health risk and may influence their health promotion practices with patients. We surveyed 361 nursing (n = 193) and medicine (n = 168) students studying at a UK medical school. Questionnaire survey, active over 12 months in 2014-2015. Measures included physical activity level, benefits and barriers to exercise, social support, perceived stress and self-efficacy for exercise. Many nursing and medicine students did not achieve recommended levels of physical activity (nursing 48%; medicine 38%). Perceived benefits of exercise were health related, with medicine students identifying additional benefits for stress relief. Most notable barriers to exercise were as follows: lack of time, facilities having inconvenient schedules and exercise not fitting around study or placement schedules. Nursing students were less active than medicine students; they perceived fewer benefits and more barriers to exercise and reported lower social support for exercise. Physical activity of nursing and medicine students was best predicted by self-efficacy and social support, explaining 35% of the variance. Physical activity should be promoted in nursing and medicine students. Interventions should aim to build self-efficacy for exercise and increase social support. Interventions should be developed that are targeted specifically to shift-working frontline care staff, to reduce schedule-related barriers to exercise and to increase accessibility to workplace health and well-being initiatives. © 2016 John Wiley & Sons Ltd.

    Physical exercise has been shown to improve cognitive and neural functioning in older adults. The current study compared the effects of an acute bout of physical exercise with a bout of interactive mental and physical exercise (i.e., "exergaming") on executive (Stroop) task performance and event-related potential (ERP) amplitudes in younger and older adults. Results revealed enhanced executive task performance in younger and older adults after exercise, with no differences in performance between exercise conditions. Stroop (RT) performance in older adults improved more than in younger adults from pre- to post-exercise. A significant increase in EEG amplitude from pre- to post-exercise was found at the Cz site from 320 to 700 ms post-stimulus for both younger and older adults, with older adults demonstrating a larger Stroop interference effect. While younger adults exhibited overall greater EEG amplitudes than older adults, they showed no differences between congruent and incongruent trials (i.e., minimal interference). Compared to peers with higher BMI (body mass index), older adults with lower BMI showed a greater reduction in Stroop interference effects from pre- to post-exercise. The beneficial effects of an acute bout of physical exercise on cognitive and neural functioning in younger and older adults were confirmed, with no difference between standard exercise and exergaming. Findings suggest that BMI, sometimes used as a proxy for fitness level, may modulate benefits that older adults derive from an acute bout of exercise. Findings have implications for future research that seeks to investigate unique effects of exergaming when compared to standard physical exercise.

    This study adopted a qualitative research design with directed content analysis and examined the interpretations of physical activity, exercise, and sedentary behaviour by persons with multiple sclerosis. Fifty three persons with multiple sclerosis who were enrolled in an exercise trial took part in semi-structured interviews regarding personal interpretations of physical activity, exercise, and sedentary behaviours. Forty three percent of participants indicated a consistent understanding of physical activity, 42% of participants indicated a consistent understanding of exercise, and 83% of participants indicated a consistent understanding of sedentary behaviour with the standard definitions. There was evidence of definitional ambiguity (i.e., 57, 58, and 11% of the sample for physical activity, exercise, and sedentary behaviour, respectively); 6% of the sample inconsistently defined sedentary behaviour with standard definitions. Some participants described physical activity in a manner that more closely aligned with exercise and confused sedentary behaviour with exercise or sleeping/napping. Results highlight the need to provide and utilise consistent definitions for accurate understanding, proper evaluation and communication of physical activity, exercise, and sedentary behaviours among persons with multiple sclerosis. The application of consistent definitions may minimise ambiguity, alleviate the equivocality of findings in the literature, and translate into improved communication about these behaviours in multiple sclerosis. Implications for Rehabilitation The symptoms of multiple sclerosis can be managed through participation in physical activity and exercise. Persons with multiple sclerosis are not engaging in sufficient levels of physical activity and exercise for health benefits. Rehabilitation professionals should use established definitions of physical activity, exercise, and sedentary behaviours when communicating about these behaviours among persons with

    The purpose of this Position Stand is to provide an overview of issues critical to understanding the importance of exercise and physical activity in older adult populations. The Position Stand is divided into three sections: Section 1 briefly reviews the structural and functional changes that characterize normal human aging, Section 2 considers the extent to which exercise and physical activity can influence the aging process, and Section 3 summarizes the benefits of both long-term exercise and physical activity and shorter-duration exercise programs on health and functional capacity. Although no amount of physical activity can stop the biological aging process, there is evidence that regular exercise can minimize the physiological effects of an otherwise sedentary lifestyle and increase active life expectancy by limiting the development and progression of chronic disease and disabling conditions. There is also emerging evidence for significant psychological and cognitive benefits accruing from regular exercise participation by older adults. Ideally, exercise prescription for older adults should include aerobic exercise, muscle strengthening exercises, and flexibility exercises. The evidence reviewed in this Position Stand is generally consistent with prior American College of Sports Medicine statements on the types and amounts of physical activity recommended for older adults as well as the recently published 2008 Physical Activity Guidelines for Americans. All older adults should engage in regular physical activity and avoid an inactive lifestyle.

    Diabetic foot is one of the most common complications of diabetes. It has the potential risk of pathologic consequences including infection, ulceration and amputation, but a growing body of evidence suggests that physical activity and exercise may improve diabetic foot outcomes. To analyze de effects of exercise and physical activity interventions on diabetic foot outcomes. A comprehensive and systematic search was conducted according to PRISMA recommendations. Only controlled clinical trials with patients with diabetes were included. Six studies, involving 418 patients with diabetes, were included. Two studies used only aerobic exercise; two studies combined aerobic, resistance and balance exercise; and two studies combined aerobic and balance exercise by Thai Chin Chuan methods. Physical activity and exercise significantly improved nerve velocity conduction, peripheral sensory function and foot peak pressure distribution. Moreover, the ulcers incidence rate per year was lower in the intervention groups, compared with the controls [0.02 vs. 0.12]. This review suggests evidence that physical activity and exercise is an effective non-pharmacological intervention to improve diabetic foot related outcomes. Combined multi-disciplinary treatments are more effective in the prevention of foot complications in patients with diabetes. Copyright © 2018 Elsevier B.V. All rights reserved.

    Many adolescents do not meet public health recommendations for moderate-to-vigorous physical activity (MVPA). In studies of variables influencing adolescent MVPA, one that has been understudied is the affective response to exercise. We hypothesized that adolescents with a more positive affective response to acute exercise would be more active. Adolescents (N = 124; 46% male) completed two 30-min exercise tasks (above and below the ventilatory threshold [VT]), and wore ActiGraph accelerometers for 6.5 +/- 0.7 days. Affective valence was assessed before, during, and after each task. A more positive affective response during exercise below the VT was associated with greater participation in MVPA (p positive affective response to exercise will engage in more MVPA. To promote greater participation in MVPA among adolescents, programs should be designed to facilitate a positive affective experience during exercise.

    Full Text Available Chicken essence (CE is a liquid nutritional supplement made from cooking whole chickens. In traditional Chinese medicine, CE is used to support health, promote healing, increase metabolism, and relieve fatigue. However, few studies have examined the effect of CE on exercise performance and physical fatigue. We aimed to evaluate the potential beneficial effects of CE on fatigue and ergogenic functions following physical challenge in mice. Male ICR mice were divided into four groups to receive vehicle or CE by oral gavage at 0, 845, 1690, or 4225 mg/kg/day for 4 weeks. Exercise performance and anti-fatigue function were evaluated by forelimb grip strength, exhaustive swimming time, and levels of physical fatigue-related biomarkers serum lactate, ammonia, glucose, and creatine kinase (CK after physical challenge. CE supplementation dose-dependently elevated endurance and grip strength. CE supplementation significantly decreased lactate, ammonia, and CK levels after physical challenge. Tissue glycogen content, an important energy source for exercise, was significantly increased with CE supplementation. In addition, CE supplementation had few subchronic toxic effects. The supplementation with CE can have a wide spectrum of bioactivities on health promotion, performance improvement and anti-fatigue.

    Evidence is currently limited for the effect of exercise on breast cancer clinical outcomes. However, several of the reported physical benefits of exercise, including peak oxygen consumption, functional capacity, muscle strength and lean mass, cardiovascular risk factors, and bone health, have established associations with disability, cardiovascular disease risk, morbidity, and mortality. This review will summarize the clinically relevant physical benefits of exercise interventions in breast cancer survivors and discuss recommendations for achieving these benefits. It will also describe potential differences in intervention delivery that may impact outcomes and, lastly, describe current physical activity guidelines for cancer survivors.

    Advances in medical care have enabled many middle-aged and older adults to live for long periods of time. However, considerable variability is present among those people with regards to both longevity and physical health status. Physical inactivity is a significant risk factor for many chronic diseases, while exercise habituation is beneficial for the maintenance of good health and high vitality. The authors have developed the concept of so-called vital age for the assessment of health and functional status in middle-aged and older adults. The vital age is estimated using a variety of bio-medical, primarily cardiovascular risk factor parameters. Previous research has compared vital age between sedentary persons and those with obesity and chronic diseases and between sedentary persons and those with exercise habituation, and found that exercise habituation can certainly contribute to better physical vitality in previously sedentary persons as well as diseased persons.

    Despite widespread understanding of the benefits of physical activity, many adults in the United States do not meet recommended exercise guidelines. Burgeoning technologies, including wearable fitness trackers (e.g., Fitbit, Apple watch), bring new opportunities to influence physical activity by encouraging users to track and share physical activity data and compete against their peers. However, research has not explored the social processes that mediate the relationship between the use of wearable fitness trackers and intention to exercise. In this study, we applied the Theory of Planned Behavior (Ajzen, 1991) to explore the effects of two communicative features of wearable fitness devices-social sharing and social competing-on individuals' intention to exercise. Drawing upon surveys from 238 wearable fitness tracker users, we found that the relationship between the two communication features (social sharing and competing) and exercise intention was mediated by attitudes, subjective norms, and perceived behavioral control. The results suggest that the ways in which exercise data are shared significantly influence the exercise intentions, and these intentions are mediated by individuals' evaluation of exercise, belief about important others' approval of exercise, and perceived control upon exercise.

    Full Text Available BACKGROUND: Aerobic exercise reduces body fat and improves weight control, increases HDL&Vo2 max. Also improves PFI (physical fitness index which is defined as ability to carry out daily tasks with vigour and alertness without undue fatigue. Though aerobic exercise is found to improve physical fitness, the relative merits of different intensities of aerobi c exercise in improving physical fitness is still uncertain. AIM: The present study was conducted to know the Effect of High & low intensity aerobic training on physical fitness index. MATERIALS & METHODS : 80 sedentary men (18 - 40 years were randomized in to 2 equal groups (High Intensity & low intensity group . The High [80% HR max] & Low intensity [50 % HR max] groups underwent aerobic exercise training using Bicycle ergo meter (COSCO at 900kpm & 540kpm, for 15mins/day & 30mins/day respectively, 5days a week, for a period of 14weeks. Physical fitness index of each subject was recorded by Modified Harvard step test before & after intervention. RESULTS : After 14 weeks of aerobic training both the exercise groups had improvement in PFI, but high intensity gr oup had a significant (p<0.05 improvement in PFI (97.18 - 101.14 than low intensity group (98.12 - 100.6. CONCLUSION : High intensity aerobic exercise is effective in improving physical fitness.

    The results showed that the children’s computation performance was enhanced significantly in the groups with 30, or 45, or 60 min of physical exercise, but not in the groups without physical exercise. This means that even acute intensive physical training can yield positive effects on children's mathematical abilities.

    Abstract While workplace physical exercise can help manage musculoskeletal disorders, less is known about psychosocial effects of such interventions. This aim of this study was to investigate the effect of workplace physical exercise on psychosocial factors among workers with chronic musculoskeletal pain. The trial design was a 2-armed parallel-group randomized controlled trial with allocation concealment. A total of 66 slaughterhouse workers (51 men and 15 women, mean age 45 years [standard deviation (SD) 10]) with upper limb chronic musculoskeletal pain were randomly allocated to group-based strength training (physical exercise group) or individual ergonomic training and education (reference group) for 10 weeks. Social climate was assessed with the General Nordic Questionnaire for Psychological and Social Factors at Work, and vitality and mental health were assessed with the 36-item Short Form Health Survey. All scales were converted to 0 to 100 (higher scores are better). Between-group differences from baseline to follow-up were determined using linear mixed models adjusted for workplace, age, gender, and baseline values of the outcome. Mean baseline scores of social climate, mental health, and vitality were 52.2 (SD 14.9), 79.5 (SD 13.7), and 53.9 (SD 19.7), respectively. Complete baseline and follow-up data were obtained from 30 and 31 from the physical exercise and reference groups, respectively. The between-group differences from baseline to follow-up between physical exercise and reference were 7.6 (95% CI 0.3 to 14.9), −2.3 (95% CI -10.3 to 5.8), and 10.1 (95% CI 0.6 to 19.5) for social climate, mental health, and vitality, respectively. For social climate and vitality, this corresponded to moderate effect sizes (Cohen d = 0.51 for both) in favor of physical exercise. There were no reported adverse events. In conclusion, workplace physical exercise performed together with colleagues improves social climate and vitality among workers with chronic

    Full Text Available Purpose. The aim of the study was to analyse the prevalence and factors associated with not performing physical exercise in undergraduate students. Methods. The sample was composed of 2738 undergraduate students of Londrina city, Parana, Brazil. The dependent variables were: not performing physical exercise of moderate intensity for at least 30 minutes per week; not performing vigorous physical exercise for at least 20 minutes per week; not performing muscular strengthening exercises (8-12 repetitions in a week. The independent variables were gender, age, skin colour, marital status, housing, study pattern, year of course, paid work, and area of the course. Odds ratio (OR was estimated by multivariate analysis with the use of binary logistic regression. Results. The prevalence of undergraduate students not performing physical exercise of moderate intensity, of vigorous intensity, or muscular strengthening exercises was 47.3, 61.0, and 66.2%, respectively. Female sex was associated with a risk of not performing moderate physical exercise (OR = 1.23, vigorous physical exercise (OR = 1.47, and strengthening exercises (OR = 1.22. Undergraduate students of exact sciences (OR = 1.40 and 1.52, juridical sciences (OR = 1.48 and 1.51, and humanities (OR = 1.45 and 1.52 were at risk of not performing physical exercise of moderate or vigorous intensity, respectively. Being a 2nd (OR = 0.79, 3rd (OR = 0.74, or 4th (OR = 0.71 year student was bound with a lower likelihood of not performing physical exercise of moderate intensity. Conclusions. Intervention programmes with the aim of promoting physical exercise practice in undergraduate students should consider gender, year, and area of the course.

    Information regarding factors that affect the initial step to exercise behavior change among persons with physical disabilities or chronic health conditions is available in the literature but much less is known regarding perceived benefits and barriers to exercise among those who are regularly active. The purpose of this study was to examine the perceived benefits and barriers to exercise among persons with physical disabilities or chronic health conditions within action or maintenance stages of exercise. Participants (n = 152) completed the Exercise Benefits and Barriers Scale (EBBS). For data analyses, disabilities and health conditions were grouped as neuromuscular, orthopedic, cardiovascular/pulmonary, or multiple conditions. Multivariate analysis of variance (MANOVA) was conducted to determine if mean differences on EBBS benefits and barriers scores existed among disability types, between sexes, among age groups, and between physical activity levels. Sum scores were computed to determine the strongest benefit and barrier responses. No significant mean differences in EBBS scores were found between disability types, sexes, age groups, or physical activity levels (p > 0.05). Strongest benefit responses varied by group. Strongest barrier responses were the same for all demographic groups: "Exercise tires me," "Exercise is hard work for me," and "I am fatigued by exercise." EBBS scores were similar across disability/health condition, sex, age, and physical activity level. Primary benefits reported were in the areas of improved physical performance and psychological outlook whereas the primary barriers were in the area of physical exertion.

    Full Text Available ABSTRACT Introduction: Excessive physical exercise combined with certain psychic and sociodemographic factors can lead to dependence. Objective: To examine which factors lead to the emergence of exercise dependence. Methods: Sample consisted of 103 men (mean age 27.3 years, SD 6.127 who performed exercises at gyms at least three times a week in the last year or more in Novi Pazar, Sjenica, Raska and Tutin, Serbia. Participants completed questionnaires and took appropriate tests. Results: Our results showed that there is no association between exercise dependence and financial status, number of siblings, level of education, family stability, health, and medication use among the interviewees. However, it was found that the degree of exercise dependence is associated with marital status and problems with the law. Regression analysis showed that body dysmorphia, body mass index and aggressiveness are better predictors of exercise dependence. Conclusion: People whose self-perception is dismorphic have lower self-esteem, and exercise in gyms to improve their physical appearance. If we consider other characteristics, such as unfavorable BMI, problems with the lаw and being single, it is hardly surprising these individuals cross the line between healthy exercise and exercise dependence. An important finding is that aggressiveness and exercise dependence are related to problems with the law due to aggression, and body dysmorphia.

    Chronic renal failure is a severe clinical problem which has some significant socioeconomic impact worldwide and hemodialysis is an important way to maintain patients' health state, but it seems difficult to get better in short time. Considering these, the aim in our research is to update and evaluate the effects of exercise on the health of patients with chronic renal failure. The databases were used to search for the relevant studies in English or Chinese. And the association between physical exercise and health state of patients with chronic renal failure has been investigated. Random-effect model was used to compare the physical function and capacity in exercise and control groups. Exercise is helpful in ameliorating the situation of blood pressure in patients with renal failure and significantly reduces VO 2 in patients with renal failure. The results of subgroup analyses show that, in the age >50, physical activity can significantly reduce blood pressure in patients with renal failure. The activity program containing warm-up, strength, and aerobic exercises has benefits in blood pressure among sick people and improves their maximal oxygen consumption level. These can help patients in physical function and aerobic capacity and may give them further benefits.

    Physical activity and exercise participation is limited by a perceived lack of time, poor access to facilities and low motivation. The aim was to assess whether providing an exercise program to be completed at the workplace with or without direct supervision was effective for promoting health-related physical fitness and exercise participation. Fifty university employees aged (Mean ± SD) 42.5 ± 11.1 years were prescribed a moderate- to vigorous-intensity aerobic and resistance exercise program to be completed at an onsite facility for 8 weeks. Participants were randomly allocated to receive direct exercise supervision or not. Cardiorespiratory fitness (V̇O 2max ) and maximal muscular strength were assessed at baseline and 8 weeks. Self-report physical activity was assessed at baseline, 8 weeks and 15 months post-intervention. Attendance or exercise session volume were not different between groups. Cardiorespiratory fitness (Mean ± 95% CI); +1.9 ± 0.7 mL·kg·min -1 ; P exercise facility to complete an individually-prescribed 8-week exercise program is sufficient to improve health-related physical fitness in the short-term independent to the level of supervision provided, but does not influence long-term participation. SO WHAT?: Lower cost onsite exercise facility supervision is as effective at improving physical health and fitness as directly supervised exercise, however ongoing support may be required for sustained physical activity behaviour change. © 2017 Australian Health Promotion Association.

    As the number of older adults continues to rise worldwide, the prevention of physical disability among seniors is an increasingly important public health priority. Physical exercise is among the best known methods of preventing disability, but accumulating evidence indicates that considerable variability exists in the responsiveness of older adults to standard training regimens. Accordingly, a need exists to develop tailored interventions to optimize the beneficial effects of exercise on the physical function of older adults at risk for becoming disabled. The present review summarizes the available literature related to the use of adjuvant or alternative strategies intended to enhance the efficacy of exercise in improving the physical function of older adults. Within this work, we also discuss potential future research directions in this area. PMID:24361365

    Full Text Available This study aimed to investigate the effects of a 12-week structured exercise intervention on total physical activity and its subcategories. Twenty-three overweight or obese middle aged men with impaired glucose regulation were randomized into a 12-week Nordic walking group, a power-type resistance training group, and a non-exercise control group. Physical activity was measured with questionnaires before the intervention (1–4 weeks and during the intervention (1–12 weeks and was expressed in metabolic equivalents of task. No significant change in the volume of total physical activity between or within the groups was observed (p > 0.050. The volume of total leisure-time physical activity (structured exercises + non-structured leisure-time physical activity increased significantly in the Nordic walking group (p 0.050 compared to the control group. In both exercise groups increase in the weekly volume of total leisure-time physical activity was inversely associated with the volume of non-leisure-time physical activities. In conclusion, structured exercise intervention did not increase the volume of total physical activity. Albeit, endurance training can increase the volume of high intensity physical activities, however it is associated with compensatory decrease in lower intensity physical activities. To achieve effective personalized exercise program, individuality in compensatory behavior should be recognised.

    Health professionals recognize the benefits of moderate physical activity and encourage clients to engage in some form of activity on a regular basis. In spite of these recognized benefits, there are growing concerns that some may exercise at levels detrimental to health. The term exercise dependence refers to those individuals whose extreme exercise schedules interfere with their social, occupational, and family lives. The purpose of this study was to examine the relationship between weekly exercise habits and scores on the Exercise Dependence Questionnaire in a sample of undergraduate students (213 women and 79 men). Overall, participants who reported high activity scored higher than those reporting low activity on subscales measuring interference with family and social life, positive reward, withdrawal, exercise for social reasons, exercise for health reasons, and stereotyped behavior.

    [Purpose] This study examined the effects of band exercise types on the physical ability and muscular topography for elderly females. [Subjects and Methods] Twenty-six females older than 65 years were divided into the dynamic band exercise (DBE; n=13) group and the Static band exercise (SBE; n=13) group. Each participant performed 12 weeks of elastic band exercises. Physical abilities were measured by leg extension power, sitting trunk flexion, closed eyes foot balance, and time to get up. Changes in muscle topography were evaluated with Moire measurement equipment for the chest, abdomen, and lumbar region. All results were compared before and after 12 weeks of exercise. [Results] Changes in physical ability were significantly increased in both groups. The scores for the muscular topography of the chest, abdomen, lumbar region, and all body parts was significantly improved in both groups for closed eyes foot balance. There were more improvements in the DBE group. [Conclusion] Two types of static and dynamic elastic band exercises effectively changed the physical fitness and muscle topography of elderly females. Therefore, to increase the effects of exercise, dynamic band exercises are considered useful. Because band exercises are simple, they can be used to maintain the health of elderly people.

The participants in the research were boys of the 5th grade (n = 32, 6th grade (n = 40, 7th grade (n = 52. To achieve the tasks set, the research used the following methods: analysis of scientific and methodological literature; pedagogical testing, pedagogical observation, timing of educational tasks; pedagogical experiment, medical and biological research methods; methods of mathematical statistics, methods of mathematical experiment planning. In order to achieve the objective set, the research has studied the effect of different variants of the educational process structure, namely: the number of repetitions (х1 and rest intervals (х2 when learning the technique of performing physical exercises. The research has conducted a complete factor experiment of type 22. According to the experiment plan, the 5th-7th graders were divided into training groups. In total, there were 12 experimental groups organized. Research results. The analysis of the regression equations shows that the teaching of physical exercises to the 5th-7th-grade boys is mostly influenced by rest intervals between repetitions (х2. The number of repetitions (х1 has somewhat less influence. The interaction of these factors is insignificant when teaching physical exercises and becomes much more influential only when teaching a switch leg pull-over exercise (х1х2. Conclusions. To increase the effectiveness of teaching 5th-7th graders physical exercises, it is necessary to shorten rest intervals between repetition to 60 s and to reduce the number of repetitions to six. When teaching boys the switch leg pull-over exercise, rest intervals should be increased to 120 s and the number of repetitions — to twelve.

    Physical inactivity not only places women's health at risk during menopause, but also increases menopausal problems. Abundant evidence links habitual physical exercise (PE) to a better status on numerous health indicators and better quality of life and to the prevention and treatment of the ailments that typically occur from mid-life onwards. We can infer that PE is something more than a lifestyle: it constitutes a form of therapy in itself. A panel of experts from various Spanish scientific societies related to PE and menopause (Spanish Menopause Society, Spanish Cardiology Society, Spanish Federation of Sports Medicine) met to reach a consensus on these issues and to decide the optimal timing of and methods of exercise, based on the best evidence available.

    The 20th and 21st centuries are marked by an increase in life expectancy on one hand and on the other hand by the increase of so called civilization diseases. Their share one common trait: the energy metabolism imbalance, with low energy expenditure and high energy uptake. Our age can be viewed as the age of inactivity and wealth. The aim of the present review is to highlight the influence of habitual physical activity on energy metabolism and balance. Energy balance is the difference between energy intake and energy expenditure, where energy expenditure further divides into resting metabolic rate, thermic effect of feeding and energy used by physical activity. In general population, resting metabolic rate remains constant and proportional to muscle body mass. Muscle mass increases with exercise, especially resistance exercise, concomitantly with increasing energy expenditure. The effect of exercise on appetite is very strong, proportional to exercise intensity. An acute bout of aerobic exercise suppresses appetite by decreasing ghrelin plasma levels, and increasing gut hormones. Different subgroups of patients respond differently to the same exercise or habitual activity and have thus distinct effects on energy balance. Different myokines plasma levels after exercise could explain these different reactions although most of their effect is still unclear. Physical activity plays an important role in the prevention and treatment of many disorders, like obesity, type 1 and type 2 diabetes, dyslipidaemia, hypertension, coronary heart disease, osteoporosis, psychiatric and neurologic disorders. It is evident, that physical activity has an effect not only on energy balance but also has a direct effect on other body organ via its own molecules - myokines. The pharmacological effect of myokines gives hope that one day we could have a "myokine drug" that could be used in patients who are unable to exercise. Until then we should use our "muscle-pharmacy" and try to convince

Material and methods The study involved 196 first year students of Division of Physiotherapy, Faculty of Military Medicine, Medical University of Lodz. Personal exercise practice and attitudes towards physical activity were assessed by questionnaire. Results Taking professional sports training was declared only by 4 % of respondents and amateur sports training by more than half of the physiotherapy students (57%. Only 3% of future physiotherapist practiced sports 5 times a week or more, 19% 3-4 times a week, 32% - rarely, but steadily. Almost half of respondents (46 % said that they do not take physical activity regularly. 39% of future physiotherapists admitted that apart from compulsory classes at the University they practiced no additional physical activity. Statistically significant difference was found in sports participation between man and women (p<0.00378. Conclusions Physiotherapy students are aware about the beneficial effects of regular physical activity on health but this knowledge is not correlated with personal exercise behavior. The level of physical activity among future physiotherapists is not greater than among the rest of the society. In the education of future physiotherapists the emphasis should be placed on increasing the level of physical activity, so necessary in this profession.

    The objective of this study was to evaluate cardiac autonomic control and muscle vasodilation response during isometric exercise in sedentary and physically active older adults. Twenty healthy participants, 10 sedentary and 10 physically active older adults, were evaluated and paired by gender, age, and body mass index. Sympathetic and parasympathetic cardiac activity (spectral and symbolic heart rate analysis) and muscle blood flow (venous occlusion plethysmography) were measured for 10 minutes at rest (baseline) and during 3 minutes of isometric handgrip exercise at 30% of the maximum voluntary contraction (sympathetic excitatory maneuver). Variables were analyzed at baseline and during 3 minutes of isometric exercise. Cardiac autonomic parameters were analyzed by Wilcoxon and Mann–Whitney tests. Muscle vasodilatory response was analyzed by repeated-measures analysis of variance followed by Tukey’s post hoc test. Sedentary older adults had higher cardiac sympathetic activity compared to physically active older adult subjects at baseline (63.13±3.31 vs 50.45±3.55 nu, P=0.02). The variance (heart rate variability index) was increased in active older adults (1,438.64±448.90 vs 1,402.92±385.14 ms, P=0.02), and cardiac sympathetic activity (symbolic analysis) was increased in sedentary older adults (5,660.91±1,626.72 vs 4,381.35±1,852.87, P=0.03) during isometric handgrip exercise. Sedentary older adults showed higher cardiac sympathetic activity (spectral analysis) (71.29±4.40 vs 58.30±3.50 nu, P=0.03) and lower parasympathetic modulation (28.79±4.37 vs 41.77±3.47 nu, P=0.03) compared to physically active older adult subjects during isometric handgrip exercise. Regarding muscle vasodilation response, there was an increase in the skeletal muscle blood flow in the second (4.1±0.5 vs 3.7±0.4 mL/min per 100 mL, P=0.01) and third minute (4.4±0.4 vs 3.9±0.3 mL/min per 100 mL, P=0.03) of handgrip exercise in active older adults. The results indicate that

    This study examines the impact of a resistance-band functional exercise program, compared with a recreational exercise program, on physical fitness and reaction times in persons older than 60 years. Fifty-four community-dwelling volunteers (71.76 ± 6.02 years) were assigned to a specific exercise program: Functional activity program (focused on resistance-band multi-joint activities; experimental group, EG), or recreational physical activity program (with gross motor activities of ludic content; control group, CG). Before and after the intervention, we determined cognitive capacity in terms of simple reaction time (S-RT), choice reaction time (C-RT) and fitness. In both groups physical performance improved, though this improvement was more marked in the EG for grip strength, arm strength and gross motor abilities (p program using a resistance band improves fitness and cognitive performance in healthy older adults. Key pointsBetter cognitive processes can be achieved as physical condition improvesExercise sessions of a more recreational type do not seem to constitute a stimulus able to improve both physical and cognitive performance in healthy active older adultsThe improvement of cognitive function, as assessed through reaction times, seems more linked to the workload and strength component of the training program.

    The aim of this study is to identify factors associated with musculo-skeletal pain reduction during workplace-based or home-based physical exercise interventions among healthcare workers. Two hundred female healthcare workers (age: 42.0, BMI: 24.1, average pain intensity: 3.1 on a scale of 0-10) from three hospitals participated. Participants were randomly allocated at the cluster level (18 departments) to 10 weeks of (i) workplace physical exercise (WORK) performed in groups during working hours for 5 × 10 minutes per week and up to five group-based coaching sessions on motivation for regular physical exercise, or (ii) home-based physical exercise (HOME) performed alone during leisure-time for 5 × 10 minutes per week. Linear mixed models accounting for cluster identified factors affecting pain reduction. On average 2.2 (SD: 1.1) and 1.0 (SD: 1.2) training sessions were performed per week in WORK and HOME, respectively. The multi-adjusted analysis showed a significant effect on pain reduction of both training adherence (P=.04) and intervention group (P=.04) with participants in WORK experiencing greater reductions compared with HOME. Obesity at baseline was associated with better outcome. Leisure-time exercise, daily patient transfer, age, and chronic pain did not affect the changes in pain. In conclusion, even when adjusted for training adherence, performing physical exercise at the workplace is more effective than home-based exercise in reducing musculo-skeletal pain in healthcare workers. Noteworthy, obese individuals may especially benefit from physical exercise interventions targeting musculo-skeletal pain. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Exercise and physical activity have been found to be beneficial in managing disabilities caused by multiple sclerosis. Despite the known benefits, many people with multiple sclerosis are inactive. This study aimed to identify the prioritised exercise and physical activity practices of people with multiple sclerosis living in the community and the reasons why they are engaged in these activities. A four Round Delphi questionnaire scoped and determined consensus of priorities for the top 10 exercise and physical activities and the reasons why people with multiple sclerosis (n = 101) are engaged in these activities. Data were analysed using content analysis, descriptive statistics, and non-parametric tests. The top 10 exercise and physical activity practices and the top 10 reasons why people with multiple sclerosis (n = 70) engaged in these activities were identified and prioritised. Consensus was achieved for the exercise and physical activities (W = 0.744, p multiple sclerosis engaged in exercise and physical activity were diverse. These self-selected activities and reasons highlighted that people with multiple sclerosis might conceptualise exercise and physical activity in ways that may not be fully appreciated or understood by health professionals. Considerations of the views of people with multiple sclerosis may be essential if the goal of increasing physical activity in this population is to be achieved. Implications for Rehabilitation Health professionals should work collaboratively with people with multiple sclerosis to understand how they prioritise activities, the underlying reasons for their prioritisations and embed these into rehabilitation programmes. Health professionals should utilise activities prioritised by people with multiple sclerosis in the community as a way to support, promote, and sustain exercise and physical activity in this population. Rehabilitation interventions should include both the activities people with multiple

    Full Text Available Abstract Background Physical activity has been associated with a decreased risk for breast cancer. The biological mechanismn(s underlying the association between physical activity and breast cancer is not clear. Most prominent hypothesis is that physical activity may protect against breast cancer through reduced lifetime exposure to endogenous hormones either direct, or indirect by preventing overweight and abdominal adiposity. In order to get more insight in the causal pathway between physical activity and breast cancer risk, we designed the Sex Hormones and Physical Exercise (SHAPE study. Purpose of SHAPE study is to examine the effects of a 1-year moderate-to-vigorous intensity exercise programme on endogenous hormone levels associated with breast cancer among sedentary postmenopausal women and whether the amount of total body fat or abdominal fat mediates the effects. Methods/Design In the SHAPE study, 189 sedentary postmenopausal women, aged 50–69 years, are randomly allocated to an intervention or a control group. The intervention consists of an 1-year moderate-to-vigorous intensity aerobic and strenght training exercise programme. Partcipants allocated to the control group are requested to retain their habitual exercise pattern. Primary study parameters measured at baseline, at four months and at 12 months are: serum concentrations of endogenous estrogens, endogenous androgens, sex hormone binding globuline and insuline. Other study parameters include: amount of total and abdominal fat, weight, BMI, body fat distribution, physical fitness, blood pressure and lifestyle factors. Discussion This study will contribute to the body of evidence relating physical activity and breast cancer risk and will provide insight into possible mechanisms through which physical activity might be associated with reduced risk of breast cancer in postmenopausal women.

    The use of nutritional supplements is prevalent among physical exercise practitioners and some adverse effects have been reported, however not sufficiently substantial, because they originate from isolated cases. Investigate nutritional supplements consumption prevalence and adverse effects of the use of such products. An epidemiological, representative and transversal study, with 180 physical exercise practitioners in gyms, who answered questionnaires about sports supplementation, associated factors and self-perceived adverse effects. In a subsample of 86 individuals, blood pressure was measured and blood was collected for the evaluation of lipid profile markers, hepatic and renal function. The supplementation prevalence level was 58.3%, whereas the physicians and nutritionists indicated only 21.9%. The reported adverse effects were observed only by supplement users (acne, insomnia, aggressiveness, headaches and tachycardia). Systolic blood pressure was higher in the supplemented group when compared to the control group (p = 0.04), as in the subgroup of thermogenic users (p nutritional supplements without specialized orientation was elevated among physical exercise practitioners, being associated to adverse effects both by the users themselves and by clinical diagnosis.

    Full Text Available Introduction Dizziness is a symptom that can lead to falls, which, in turn, undermine onés independence and autonomy, leading to several comorbidities. The practice of physical exercise, however, can help prevent falls. Objective The objective of this study is to confirm the association between physical exercise, dizziness, probability of falling, and depressive symptoms in a group of middle-aged adults and seniors. Methods The authors evaluated subjects based on history, the Geriatric Depression Scale, and functional reach test. Results The sample consisted of 90 individuals with a mean age of 69.3 ± 6.8 years. The authors found that 37.8% had been practicing exercise, 33.7% had depressive symptoms, and their probability of falling was above average in the functional reach test. Conclusion The results of this study indicated an association between dizziness, exercise practice and depressive symptoms, indicating that physical activity is a beneficial factor for the aging population.

    (1) Background: Green physical activity promotes physical health and mental wellbeing and interesting questions concern effects of this information on designing indoor exercise environments. This study examined the physical and emotional effects of different nature-based environments designed for indoor treadmill running; (2) Methods: In a counterbalanced experimental design, 30 participants performed three, twenty-minute treadmill runs at a self-selected pace while viewing either a static nature image, a dynamic nature image or self-selected entertainment. Distance ran, heart rate (HR) and five pre-and post-exercise emotional states were measured; (3) Results: Participants ran farther, and with higher HRs, with self-selected entertainment compared to the two nature-based environment designs. Participants attained lowered anger, dejection, anxiety and increased excitement post exercise in all of the designed environments. Happiness increased during the two nature-based environment designs compared with self-selected entertainment; (4) Conclusions: Self-selected entertainment encouraged greater physical performances whereas running in nature-based exercise environments elicited greater happiness immediately after running.

    This study showed that about a half of the exercise-induced gain in dynamic balance and bone strength was maintained one year after cessation of the supervised high-intensity training of home-dwelling elderly women. However, to maintain exercise-induced gains in lower limb muscle force and physical functioning, continued training seems necessary. Maintenance of exercise-induced benefits in physical functioning and bone structure was assessed one year after cessation of 12-month randomized controlled exercise intervention. Originally 149 healthy women 70-78 years of age participated in the 12-month exercise RCT and 120 (81%) of them completed the follow-up study. Self-rated physical functioning, dynamic balance, leg extensor force, and bone structure were assessed. During the intervention, exercise increased dynamic balance by 7% in the combination resistance and balance-jumping training group (COMB). At the follow-up, a 4% (95% CI: 1-8%) gain compared with the controls was still seen, while the exercise-induced isometric leg extension force and self-rated physical functioning benefits had disappeared. During the intervention, at least twice a week trained COMB subjects obtained a significant 2% benefit in tibial shaft bone strength index compared to the controls. A half of this benefit seemed to be maintained at the follow-up. Exercise-induced benefits in dynamic balance and rigidity in the tibial shaft may partly be maintained one year after cessation of a supervised 12-month multi-component training in initially healthy elderly women. However, to maintain the achieved gains in muscle force and physical functioning, continued training seems necessary.

    This review examines the relationship between physical activity and cancer along the cancer continuum, and serves as a synthesis of systematic and meta-analytic reviews conducted to date. There exists a large body of epidemiologic evidence that conclude those who participate in higher levels of physical activity have a reduced likelihood of developing a variety of cancers compared to those who engage in lower levels of physical activity. Despite this observational evidence, the causal pathway underling the association between participation in physical activity and cancer risk reduction remains unclear. Physical activity is also a useful adjunct to improve the deleterious sequelae experienced during cancer treatment. These deleterious sequelae may include fatigue, muscular weakness, deteriorated functional capacity, including many others. The benefits of physical activity during cancer treatment are similar to those experienced after treatment. Despite the growing volume of literature examining physical activity and cancer across the cancer continuum, a number of research gaps exist. There is little evidence on the safety of physical activity among all cancer survivors, as most trials have selectively recruited participants. It is also unclear the specific dose of exercise needed that is optimal for primary cancer prevention or symptom control during and after cancer treatment. PMID:23720265

    Full Text Available Motor performance deficits of older adults are due to dysfunction at multiple levels. Age-related differences have been documented on executive functions; motor control becomes more reliant on cognitive control mechanisms, including the engagement of the prefrontal cortex (PFC, possibly compensating for age-related sensorimotor declines. Since at functional level the PFC showed the largest age-related differences during discriminative response task, we wonder whether those effects are mainly due to the cognitive difficulty in stimulus discrimination or they could be also detected in a much easier task. In the present study, we measured the association of physical exercise with the PFC activation and response times (RTs using a simple response task (SRT, in which the participants were asked to respond as quickly as possible by manual key-press to visual stimuli. Simultaneous behavioral (RTs and electroencephalographic (EEG recordings were performed on 84 healthy participants aged 19-86 years. The whole sample was divided into three cohorts (young, middle-aged and older; each cohort was further divided into two equal sub-cohorts (exercise and not-exercise based on a self-report questionnaire measuring physical exercise. The EEG signal was segmented in epochs starting 1100 prior to stimulus onset and lasting 2-s. Behavioral results showed age effects, indicating a slowing of RTs with increasing age. The EEG results showed a significant interaction between age and exercise on the activities recorded on the PFC. The results indicates that: a the brain of older adults needs the PFC engagement also to perform elementary task, such as the SRT, while this activity is not necessary in younger adults, b physical exercise could reduce this age-related reliance on extra cognitive control also during the performance of a SRT, and c the activity of the PFC is a sensitive index of the benefits of physical exercise on sensorimotor decline.

    Cognitive dysfunction is highly prevalent, disabling, and poorly-managed in persons with multiple sclerosis (MS). Recent evidence suggests that exercise might have beneficial effects on cognition in this population. The current systematic, evidence-based review examined the existing literature on exercise, physical activity, and physical fitness effects on cognition in MS to accurately describe the current status of the field, offer recommendations for clinicians, and identify study-specific and participant-specific characteristics for providing future direction for ongoing MS research. We performed an open-dated search of Medline, PsychInfo, and CINAHL in December 2015. The search strategy involved using the terms 'exercise' OR 'physical activity' OR 'physical fitness' OR 'aerobic' OR 'resistance' OR 'balance' OR 'walking' OR 'yoga' OR 'training' OR 'rehabilitation' AND 'multiple sclerosis'. Articles were eliminated from the systematic review if it was a review article, theoretical paper, or textbook chapter; did not involve persons with MS; involved only persons with pediatric-onset MS; did not involve neuropsychological outcomes; did not include empirical data to evaluate outcomes; involved pharmacological interventions; or was not available in English. The selected articles were first classified as examining exercise, physical activity, or physical fitness, and were then randomly assigned to 2 independent reviewers who rated each article for level of evidence based on American Academy of Neurology criteria. Reviewers further completed a table to characterize important elements of each study (i.e., intervention characteristics), the cognitive domain(s) that were targeted, participant-specific characteristics, outcome measures, and study results. The present review resulted in 26 studies on the effects of exercise, physical activity, and physical fitness on cognition in persons with MS. This included 1 Class I study, 3 Class II studies, 8 Class III studies, and

    Many studies have highlighted the importance of physical activity (PA) for health, and recent evidence now points to the positive improvements associated with exercise in type 2 diabetes mellitus (T2DM). However, few physicians are willing to prescribe exercise as a therapy for diabetic patients. In addition, there is a lack of information on how to implement exercise therapy especially in long-term exercise regimens. The purpose of this manuscript is to summarize standards of exercise therapy for patients with T2DM, both in terms of prescribing and monitoring, according to the American College of Sports Medicine and the American Diabetes Association guidelines. We present details of the exercise therapies used in long-term studies, describing how the parameters for exercise prescription were applied in clinical practice. These parameters are described in terms of frequency, intensity, duration, mode and rate of progression in long-term therapeutic prescriptions. Individual responses to exercise dose are discussed, and critical issues to be considered in patients with underlying disease and in T2DM patients are highlighted.

    A review of the Survey on the State of Employees' Health by the Ministry of Health, Labour and Welfare (2008) shows that the most commonly implemented aspect as an activity of worksite health promotion is "Health counseling", and the second is "Workplace physical exercise." Physical exercise, "Taiso", is acceptable and sustainable for workers, as it is easy to do in a group or alone. Various modes of stretching are implemented for workplace physical exercise. However, articles suggesting negative or contradictory effects of stretching have increased in recent years. Several review articles have revealed that static stretching may induce impairments of muscle power performance and no stretching will prevent or reduce muscle soreness after exercise. There are various aims of workplace physical exercise, so we have to consider the situational method when we apply stretching to occupational health.

    African American women continue to have the highest prevalence of obesity in the United States and in the state of Maryland they are disproportionately affected by overweight and obesity. There are many contributing factors including chronic stress and the use of health behaviors such as physical exercise that play a role in increased weight for African American women. We examined the relationship of stress to weight and the role of physical exercise in African American paraprofessional women. Cross-sectional study African American paraprofessionals were asked about their perspectives regarding association with chronic stress and physical exercise. The three most salient stressors for the women were finances (33%), work (28%) and family/friends (19%). Ninety percent of the women were overweight or obese. Significant predictors of increased BMI were lack of physical exercise (P = .004) and health compared to others (P = .006). Ethnic discrimination was a form of chronic stress (r = .319) but was not correlated with BMI (r = .095). Decreased physical exercise (P = .02) mediated the relationship between chronic stress and BMI. Findings regarding finance and work stress suggest the need for employers to consider the impact of job strain when implementing employee health programs to decrease stress and improve health. A focus on decreased physical exercise, unhealthy eating habits and misperceptions regarding increased risk for obesity related diseases with health status may be helpful to include in intervention strategies to decrease obesity for this population.

    2017-03-09

    This article presents the results from a large nationwide survey completed in 2016 that investigated the physical health and wellbeing of people living with stomas in the UK. In particular, the survey looked at physical activity and exercise, general attitudes and opinions about exercise, whether or not advice about physical activity had been received and other general questions about parastomal hernia and quality of life. There were 2631 respondents making it one of the largest known surveys to date. The findings were concerning yet unsurprising, highlighting a trend toward inactivity after stoma surgery and a fear of exercise in general. People also seem to have poor knowledge about appropriate activities, with many suggesting that the fear of developing a parastomal hernia is a major barrier to activity. Unsurprisingly, those who have a stoma owing to cancer seem to fare worse, reporting even lower levels of physical activity and worse quality of life compared to those with other conditions. This indicates that people who have a combination of a cancer diagnosis and also a stoma may need more specific or additional support in the longer term. The most concerning finding, however, was that the majority of patients could not recall being given any advice about exercise or physical activity by their nurse or surgeon. While this survey presents some initial findings, it raises questions for further research and work. It also highlights a significantly neglected area in both research and support for stoma patients and the health professionals caring for them.

    To gain a better understanding of how children aged 6-18 years who use wheelchairs and their families conceptualized physical exercise and keeping fit. Disabled children with reduced mobility are commonly overweight and unfit. Nurse-led health screening programmes in schools commonly exclude disabled children if they cannot use standard weighing scales or stand against height measuring sticks. Qualitative interview study at two time points over 6 months with children who use wheelchairs and their families. Framework analysis using the theory of planned behaviour. Mainly physically active participants were recruited (24 children and 23 parents) 2013-2014. Despite engaging in high levels of physical exercise, children were assessed as fit but had elevated body fat and did not realize how fit they were or that they were slightly overweight and nor did their parents. Children enjoyed the social benefits of exercise. Unlike their parents, children confused the purpose and outcomes of physical exercise with therapy (e.g. physiotherapy) and incorrectly understood the effects of physical exercise on body function and strength, preventing stiffness, increasing stamina and reducing fatigue. A new model was developed to show children's misconceptions. Proactive parents can overcome barriers to enable their children to benefit from physical exercise. Professionals need to increase communication clarity to improve children's understanding of therapy compared with physical exercise outcomes. Inclusion of children who use wheelchairs in health education policy; routine health screening; physical education classes and teacher training requires improvement. Body composition measurement is recommended, for which nurses will need training. © 2016 The Authors. Journal of Advanced Nursing Published by John Wiley & Sons Ltd.

    Full Text Available This study investigated the effects of aerobic exercises training with different modes of physical activity on cardiovascular fitness and mental health. In this regard, 20 young healthy male participants (18 to 30 years were included in this study. They were divided into 2 groups, 10 in each, groups A and group B. Group A participated in combined limb exercise while Group B participated in walking exercise training under the supervision of a physical trainer. Resting and maximum pulse, resting and maximum systolic and diastolic blood pressure, Treadmill walking exercise fatigue time (TWEFT and general health questionnaire GHQ-12 were analyzed in both groups before and after the exercise training. Students paired t test was applied for pre and post data analysis. Results showed resting pulse, resting and maximum SBP and TWEFT decrease significantly (p<0.05 after combined limb exercise. Walking exercise alone causes decrease in resting pulse and GHQ score. In conclusion combined limb exercise is more beneficial than walking exercise alone. The cardiovascular fitness is improved after combined limb exercise while the mental well being is more pronounced after walking exercise alone. It can be suggested that combination of both forms of physical activity is the proper way to improve cardiovascular fitness and mental well being simultaneously, if practiced regularly.

    Physical Activity in the workplace has received special attention from researchers who are looking to promote lifelong health and well-being. The workplace is being investigated as a possible place to assess and create strategies to help people to become healthier. The transtheoretical model and stages of change has been adapted as a tool to assess the stages of behavioral change towards exercising. To assess the change in health behavior following a three-month exercise program based in the workplace. A quasi-experimental study design was used in which 165 employees participated in the study. An intervention program of workplace exercise was applied for three months. Participants were assessed through the transtheoretical model and stages of change questionnaire before and after intervention to understand changes in their position on the behavioral change continuum. The number of employees who were physically active increased after the workplace exercise intervention (13.9% , 95% CI 9.5 to 20.1; P = 0.009). There was a significant decrease in the proportion of employees in the pre-contemplation stage (-6.1% , 95% CI 3.3 to 10.8; P = 0.045) and contemplation stage (-11.5% , 95% CI 7.5 to 17.3; P = 0.017), and a significant increase in the action stage (10.9% , 95% CI 7.0 to 16.6; P = 0.003). Engaging in workplace exercise has a significant positive effect on health behavior and willingness to become more physically active.

    Researchers have yet to establish how interventions to increase physical activity influence specific self-efficacy beliefs. The current study sought to quantify the effect of interventions to increase physical activity among healthy adults on exercise task (EXSE) and barrier self-efficacy (BSE) via meta-analysis. Intervention characteristics associated with self-efficacy and physical activity changes were also identified. A systematic database search and manual searches through reference lists of related publications were conducted for articles on randomized, controlled physical activity interventions. Published intervention studies reporting changes in physical activity behavior and either EXSE or BSE in healthy adults were eligible for inclusion. Of the 1,080 studies identified, 20 were included in the meta-analyses. Interventions had a significant effect of g = 0.208, 95% confidence interval (CI) [0.027, 0.388], p exercise sessions effectively increased EXSE and physical activity, whereas long interventions improved BSE. Interventions that did not provide support increased BSE and physical activity levels. Further, interventions that did not require the use of daily exercise logs improved EXSE and physical activity behavior. Interventions designed to increase physical activity differentially influenced EXSE and BSE. EXSE appeared to play a more significant role during exercise adoption, whereas BSE was involved in the maintenance of exercise behavior. Recommendations are offered for the design of future interventions.

    This randomized-controlled trial investigated the effect of physical exercise programme (PEP) on happiness among older adults in Nowshahr, Iran. Results of this study on 120 male and female volunteers showed that an 8-week group physical exercise programme was significantly effective in older adults' happiness. Findings showed that physical exercise programme is so beneficial for increasing older adults' happiness. Physical activity is associated with well-being and happiness. The purpose of this study was to determine the effects of an 8-week long physical exercise programme (PEP) on happiness among older adults in Nowshahr, Iran. This was a randomized control trial study. The participants consisted of a group of 120 male and female volunteers (mean ± SD age: 71 ± 5.86 years) in a convenience sampling among older adults in public parks in Nowshahr, Iran. We randomly allocated them into experimental (n = 60) and control (n = 60) groups. A validated instrument was used to measure well-being and happiness [Oxford Happiness Inventory (OHI)]. Respondents were asked to complete the OHI before and 2 months after implementing PEP. The 8-week PEP was implemented with the intervention group. The statistical analysis of the data was conducted using paired t-test, Fisher's exact test and χ(2). Before the intervention, there was no significant difference in the happiness mean score between the case and control groups; however, after implementing PEP, happiness significantly improved among the experimental group (P = 0.001) and did not improve within the control group (P = 0.79). It can be concluded that PEP had positive effects on happiness among older adults. Planning and implementing of physical activity is so important for older happiness. © 2014 John Wiley & Sons Ltd.

    Heart rate variability is controlled by the influence of autonomic nervous system, whereas one part of the system modulates the activity of the other. There is evidence of increased sympathetic activity in patients (pts) with essential hypertension. The aim of the study was to assess the persisting influence of increased sympathetic activity 30 min after moderate physical exercise on heart rate variability in patients with arterial hypertension. The study was performed in 19 patients (10 women, mean age 52.7 +/- 9.5 years and 9 men, mean age 37.7 +/- 8.8 years) with stage I (6 pts) and stage II (13 pts) arterial hypertension. All studied pts had sinus rhythm, were free of diabetes, coronary heart disease and congestive heart failure. 24-hour Holter monitoring was performed and for 30 min before the exercise test the pts stayed in supine rest. The exercise tests were performed between 10 and 11 a.m. Immediately after the exercise all pts stayed in supine position for 30 min. The heart rate variability parameters were studied using Holter monitoring system Medilog Optima Jet and were then analysed statistically. The mean energy expenditure during the exercise was 5.8 +/- 1.1 METs and the maximal heart rate was 148.1 +/- 20.3 bpm. All studied HRV parameters were significantly different in the assessed time period compared to the baseline values (p < 0.001). Significant correlation was found between the age of the studied patients and the mean RR interval, what can be considered as a hyperkinetic (hyperadrenergic) circulatory status and shorter RR interval in younger pts. Significant negative correlation between the age and SDNN parameter (r = -0.65, p < 0.001), 30 min after the exercise mirrors the prolonged adrenergic influence in older pts. The present study shows that the influence of moderate physical exercise on heart rate variability in pts with essential hypertension is extended over 30 min period after exercise and is more pronounced in older pts.

    Women significantly decrease their activity levels in the transition to motherhood. Digital health technologies are low cost, scalable, and can provide an effective delivery mechanism for behavior change. This is the first study that examines the use of videoconferencing and mobile apps to create exercise groups for mothers. The aim of the study was to test the feasibility, acceptability, and effectiveness of an individually adaptive and socially supportive physical activity intervention incorporating videoconferencing and mobile apps for mothers. The Moms Online Video Exercise Study was an 8-week, 2-armed, Web-based randomized trial comparing the effectiveness of a group exercise intervention with a waitlist control. Healthy mothers with at least 1 child under the age of 12 years were recruited through Facebook and email listservs. Intervention participants joined exercise groups using videoconferencing (Google Hangouts) every morning on weekdays and exercised together in real time, guided by exercise mobile apps (eg, Nike+, Sworkit) of their choice. Waitlist control participants had access to recommended mobile apps and an invitation to join an exercise group after the 8-week study period. Main outcomes assessed included changes in self-reported moderate, vigorous, and moderate to vigorous physical activity (MVPA) minutes per week in aggregate and stratified by whether women met Centers for Disease Control and Prevention guidelines for sufficient aerobic activity at baseline. Outcomes were measured through self-assessed Web-based questionnaires at baseline and 8 weeks. The intervention was effective at increasing exercise for inactive women and proved to be feasible and acceptable to all participants. A total of 64 women were randomized, 30 to intervention and 34 to control. Women attended 2.8 sessions per week. There was a strong, but not statistically significant, trend toward increasing moderate, vigorous, and MVPA minutes for all women. As hypothesized, in

    Clinical guidelines recommend knee muscle strengthening exercises to improve physical function. However, the amount of knee muscle strength increase needed for clinically relevant improvements in physical function is unclear. Understanding how much increase in knee muscle strength is associated with improved physical function could assist clinicians in providing appropriate strength gain targets for their patients in order to optimise outcomes from exercise. The aim of this study was to investigate whether an increase in knee muscle strength is associated with improved self-reported physical function following exercise; and whether the relationship differs according to physical function status at baseline. Data from 100 participants with medial knee osteoarthritis enrolled in a 12-week randomised controlled trial comparing neuromuscular exercise to quadriceps strengthening exercise were pooled. Participants were categorised as having mild, moderate or severe physical dysfunction at baseline using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Associations between 12-week changes in physical function (dependent variable) and peak isometric knee extensor and flexor strength (independent variables) were evaluated with and without accounting for baseline physical function status and covariates using linear regression models. In covariate-adjusted models without accounting for baseline physical function, every 1-unit (Nm/kg) increase in knee extensor strength was associated with physical function improvement of 17 WOMAC units (95% confidence interval (CI) -29 to -5). When accounting for baseline severity of physical function, every 1-unit increase in knee extensor strength was associated with physical function improvement of 24 WOMAC units (95% CI -42 to -7) in participants with severe physical dysfunction. There were no associations between change in strength and change in physical function in participants with mild or moderate physical

    The presence of bone metastases has excluded participation of cancer patients in exercise interventions and is a relative contraindication to supervised exercise in the community setting because of concerns of fragility fracture. We examined the efficacy and safety of a modular multimodal exercise program in prostate cancer patients with bone metastases. Between 2012 and 2015, 57 prostate cancer patients (70.0 ± 8.4 yr; body mass index, 28.7 ± 4.0 kg·m) with bone metastases (pelvis, 75.4%; femur, 40.4%; rib/thoracic spine, 66.7%; lumbar spine, 43.9%; humerus, 24.6%; other sites, 70.2%) were randomized to multimodal supervised aerobic, resistance, and flexibility exercises undertaken thrice weekly (EX; n = 28) or usual care (CON; n = 29) for 3 months. Physical function subscale of the Medical Outcomes Study Short-Form 36 was the primary end point as an indicator of patient-rated physical functioning. Secondary end points included objective measures of physical function, lower body muscle strength, body composition, and fatigue. Safety was assessed by recording the incidence and severity of any adverse events, skeletal complications, and bone pain throughout the intervention. There was a significant difference between groups for self-reported physical functioning (3.2 points; 95% confidence interval, 0.4-6.0 points; P = 0.028) and lower body muscle strength (6.6 kg; 95% confidence interval, 0.6-12.7; P = 0.033) at 3 months favoring EX. However, there was no difference between groups for lean mass (P = 0.584), fat mass (P = 0.598), or fatigue (P = 0.964). There were no exercise-related adverse events or skeletal fractures and no differences in bone pain between EX and CON (P = 0.507). Multimodal modular exercise in prostate cancer patients with bone metastases led to self-reported improvements in physical function and objectively measured lower body muscle strength with no skeletal complications or increased bone pain.

    The goal of this meta-analysis was to aggregate available empirical studies on the effects of physical exercise on executive functions in preadolescent children (6-12 years of age), adolescents (13-17 years of age) and young adults (18-35 years of age). The electronic databases PubMed, EMBASE and SPORTDiscus were searched for relevant studies reporting on the effects of physical exercise on executive functions. Nineteen studies were selected. There was a significant overall effect of acute physical exercise on executive functions (d=0.52, 95% CI 0.29 to 0.76, pexercise (d=0.14, 95%CI -0.04 to 0.32, p=0.19) on executive functions (Q (1)=5.08, pexercise on the domain's inhibition/interference control (d=0.46, 95% CI 0.33 to 0.60, pexercise on planning (d=0.16, 95% CI 0.18 to 0.89, p=0.18). Results suggest that acute physical exercise enhances executive functioning. The number of studies on chronic physical exercise is limited and it should be investigated whether chronic physical exercise shows effects on executive functions comparable to acute physical exercise. This is highly relevant in preadolescent children and adolescents, given the importance of well-developed executive functions for daily life functioning and the current increase in sedentary behaviour in these age groups.

    Depression among nursing students is an ongoing problem. Several psychotherapies have been suggested as alternatives to antidepressants in the management of depression. The aim of this randomized controlled study was to compare the effectiveness of mindfulness meditation versus physical exercise in the management of depression among nursing students. A sample of 181 soon-to-graduate nursing students participated in the study and were assigned at random to one of two therapies: physical exercise (n = 90) or mindfulness meditation (n = 91). The Center for Epidemiologic Studies Depression Scale was completed by the participants in both groups prior to the therapies and after completion. The findings indicated that both therapies were effective in the management of depression. However, mindfulness meditation is more effective than physical exercise. Mindfulness meditation is recommended over physical exercise in the management of depression among undergraduate nursing students. [J Nurs Educ. 2017;56(10):599-604.].

    A long-term physical exercise program was established for a large number of children with bronchial asthma. Asthmatic children were first taught to swim on their backs to prevent breathing problems customary for beginners using other strokes. They concurrently participated in gymnasium exercises, and the program was later completed with outdoor running. Program effectiveness was evaluated by monitoring asthmatic symptoms, changes in medication, and changes in the activity and physical fitness of the children. Data collected from 121 children showed that during the first year in the program the number of days with asthmatic symptoms decreased in a large majority of the patients while medication was decreased. School absenteeism and hospitalization dropped markedly. Parental evaluation of the children indicated much improvement in 51.2%, improvement in 40.5%, unchanged condition in 7.4%, and deterioration of general health was only reported in one child (0.8%). The same extent of improvement continued during the second year. The Cooper test was applied for the first time to such an exercise program and indicated that the participating asthmatic children performed as well as a control group of nonasthmatic children, and the cardiovascular efficiency of the asthmatics was actually better.

    The role of social support in physical exercise is well documented. However, the majority of studies that investigate the associations between social support and physical exercise target perceived instead of received social support. Moreover, most studies investigate the effects of received social support using a descriptive correlational design. Thus, our study aimed at investigating the effects of received social support by conducting an intervention study. Participants were randomly assigned to an intervention (n = 118) or control group (n = 102). The intervention comprised regularly exercising with a new sports companion for eight weeks. To investigate the time course of physical exercise and received social support, growth curve modelling was employed. Generally, both groups were able to improve their physical exercise. However, the control group tended to decrease again during the final point of measurement. Received social support, however, decreased slightly in the control group, but remained stable in the intervention group. The intervention was suitable to sustain received social support for physical exercise across a two-month interval. Overall, these findings highlight the importance of further investigating social support for physical exercise applying an experimental approach. © 2014 The International Association of Applied Psychology.

By means of this thematisation, a medical counselling is formed, according to which exercise, gymnastics and diet aim at the maintenance and restoration of man's health; dietetics, maintenance of well-being, recovery and amelioration of man's health are involved in this thematisation. Hippocrates' views on the aforementioned issues constitute a basis for the discussion and pedagogical exploitation of them in contemporary education and, particularly, in sports education and physical exercise.

    The purpose of this study was to perform a construct validity assessment of Kendzierski's exercise self-schema theory questionnaire using objective measures of health-related physical fitness. This study tested the hypothesis that individuals with an exercise self-schema would possess significantly greater physical fitness than those who did not across three domains of health-related physical fitness: Body composition, cardiovascular fitness, and upper-body muscular endurance. Undergraduate student participants from one private university on the west coast of the United States completed informed consent forms and the exercise self-schema questionnaire within a classroom setting or at an on-campus outside tabling session. Participants not meeting inclusion criteria for Kendzierski's three original schema groups were categorized as "unschematic," and were included within MANCOVA/ANCOVA analyses, where gender served as the covariate. Participants underwent lab-based fitness assessments administered in accordance with the 2013 American College of Sports Medicine Guidelines for Exercise Testing and Prescription. The hypothesis of this study was partially supported. Specifically, exerciser schematics were significantly leaner than aschematics (p = .002) and they had greater levels of upper-body muscular endurance compared to both aschematic and nonexerciser schematics (p = .002). However, no differences were observed for cardiovascular fitness (i.e., predicted V02Max p = .410). The findings of this study help to establish the construct validity of Kendizerski's self-report exercise self-schema categorization scheme. Visual inspection of the data, as well as computed effect size measures suggest exercise self-schema is associated with dimensions of one's physical fitness.

    Full Text Available This study examines the impact of a resistance-band functional exercise program, compared with a recreational exercise program, on physical fitness and reaction times in persons older than 60 years. Fifty-four community-dwelling volunteers (71.76 ± 6.02 years were assigned to a specific exercise program: Functional activity program (focused on resistance-band multi-joint activities; experimental group, EG, or recreational physical activity program (with gross motor activities of ludic content; control group, CG. Before and after the intervention, we determined cognitive capacity in terms of simple reaction time (S-RT, choice reaction time (C-RT and fitness. In both groups physical performance improved, though this improvement was more marked in the EG for grip strength, arm strength and gross motor abilities (p < 0.05. Reaction times were better only in EG (S-RT = 10.70%, C-RT = 14.34%; p < 0.05 after the corresponding physical training intervention. The training period showed no effect on the moderate relationship between both RT and gross motor abilities in the CG, whereas the EG displayed an enhanced relationship between S-RT and grip-strength as well as the C-RT with arm strength and aerobic capacity (r ~ 0.457; p < 0.05. Our findings indicate that a functional exercise program using a resistance band improves fitness and cognitive performance in healthy older adults.

    Full Text Available The purpose of this study was to examine the benefits of physical exercise among secondary school students. Participants in the study were 251 students (120 boys and 131 girls attending three public secondary schools in the Hlanganani rural area of South Africa. A validated questionnaire was used to collect data. Results of this study indicated that students exercised to be with their friends, to be physically attractive and compete with others. The findings of this study have practical implications for promoting participation in physical activity among students in rural schools. In an effort to promote physical activity participation, schools should be provided with quality sports infrastructure and funding so that they can implement school sport programmes. Finally, the teaching of physical education should be emphasised in schools as it is the cornerstone for children’s involvement in physical activity.

  3. Exercise, physical activity, and exertion over the business cycle.

    Shifts in time and income constraints over economic expansions and contractions would be expected to affect individuals' behaviors. We explore the impact of the business cycle on individuals' exercise, time use, and total physical exertion, utilizing information on 112,000 individual records from the 2003-2010 American Time Use Surveys. In doing so, we test a key causal link that has been hypothesized in the relation between unemployment and health, but not heretofore assessed. Using more precise measures of exercise (and other activities) than previous studies, we find that as work-time decreases during a recession, recreational exercise, TV-watching, sleeping, childcare, and housework increase. This, however, does not compensate for the decrease in work-related exertion due to job-loss, and total physical exertion declines. These effects are strongest among low-educated men, which is validating given that employment in the Great Recession has declined most within manufacturing, mining, and construction. We also find evidence of intra-household spillover effects, wherein individuals respond to shifts in spousal employment conditional on their own labor supply. The decrease in total physical activity during recessions is especially problematic for vulnerable populations concentrated in boom-and-bust industries, and may have longer-term effects on obesity and related health outcomes.

    2018-05-01

    Despite the accumulated evidence for the environmental correlates of physical activity, social processes underlying this association are not entirely clear. This study positions communication characterized by weak ties as a social mechanism linking neighborhood walkability with physical exercise. Data from a survey of Chicago residents show that perceived neighborhood walkability is positively related to frequency of weak-tie communication. Frequency of weak-tie communication is related positively to perceived social cohesion and negatively to anonymity, both of which are significantly related to frequency of physical exercise in the neighborhood. Data also show a sequential indirect relationship involving perceived neighborhood walkability, weak-tie communication, anonymity, and physical exercise. Implications are discussed in terms of the role of communication in promoting locality-based physical exercise. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Physical exercises are effective in the treatment of osteoarthritis (OA). There is consensus that exercise interventions should take into account the patient's preferences and needs in order to improve compliance to exercise regimes. One important personal factor is the patient's motivation for physical exercise. Health improvement is a relevant motive for exercise participation. Accordingly, exercise interventions primarily focus on health related needs such as strengthening and pain reduction. However exercising provides further many-faceted incentives that may foster exercise adherence. The present study aimed to characterize target groups for person-tailored exercise interventions in OA according to the International Classification of Functioning and Disability and Health (ICF). Target groups should be classified by similar individual exercise participation motive profiles and further described by their disease-related symptoms, limitations and psychological determinants of exercise behavior. Observational study via self-administered questionnaires. Community. We enrolled 292 adults with hip/knee OA living independently of assistance. Participants completed the Bernese Motive and Goal Inventory in Leisure and Health Sports (BMZI), the Hannover Functional Ability Questionnaire for Osteoarthritis, the WOMAC-Index (pain/stiffness), the General Self-efficacy Scale and a questionnaire on perceived barriers to exercise participation. The BMZI-scales served as active variables for cluster analysis (Ward's method), other scales were used as passive variables to further describe the identified clusters. Four clusters were defined using five exercise participation motives: health, body/appearance, esthetics, nature, and contact. Based on the identified motive profiles the target groups are labelled health-focused sports people; sporty, nature-oriented individualists; functionalists primarily motivated by maintaining or improving health through exercise; and nature

    To examine whether knowledge of high school students' actions of self-regulation, and perceptions of self-efficacy to overcome exercise barriers, social situation, and outcome expectation will predict non-school related moderate and vigorous physical exercise. High school students enrolled in introductory Physical Education courses completed questionnaires that targeted selected Social Cognitive Theory variables. They also self-reported their typical "leisure-time" exercise participation using a standardized questionnaire. Bivariate correlation statistic and hierarchical regression were conducted on reports of moderate and vigorous exercise frequency. Each predictor variable was significantly associated with measures of moderate and vigorous exercise frequency. All predictor variables were significant in the final regression model used to explain vigorous exercise. After controlling for the effects of gender, the psychosocial variables explained 29% of variance in vigorous exercise frequency. Three of four predictor variables were significant in the final regression equation used to explain moderate exercise. The final regression equation accounted for 11% of variance in moderate exercise frequency. Professionals who attempt to increase the prevalence of physical exercise through educational methods should focus on the psychosocial variables utilized in this study.

    There is sufficient evidence showing the positive effects of physical exercise on various aspects of pregnancy. This study evaluates knowledge and status of physical exercise among pregnant women. The standardised paper-pencil questionnaire "Pregnancy Physical Activity Questionnaire" (PPAQ) as well as general demographic questions were used to assess the exercise behaviour of study participants. 83 questionnaires completed by women presenting to the Kiel University Hospital for antenatal assessment were included in the analysis. At the time of questionnaire completion 10 women were in the first trimester of pregnancy, 64 in the second, and 9 in the third. Just less than 90% of participants felt they had been informed "sufficiently" on the topic physical exercise during pregnancy, over 50% felt they were "well" or "very well" informed. Just less than half of participants received their information from a doctor (either their gynaecologist or general practitioner) and none of these felt "insufficiently" informed. Almost 80% of participants reported still doing no sport or less exercise than before falling pregnant. The maximum proportional energy expenditure for recreational activity - just under 20% - was in the third trimester. Women who felt they had been well counselled tended to have higher activity levels. Study participants demonstrated a clear decline in physical exercise during pregnancy despite clear evidence of the benefits of regular exercise for pregnant women, and despite participants feeling they were well informed. Detailed information on the recommendations for physical exertion in pregnancy should form an integral part of antenatal counselling.

    Both the beneficial relationship between exercise and quality of life and the important role played by exercise self-efficacy in maintaining an exercise regimen among individuals with chronic heart failure are well known. However, most nursing interventions for Korean patients with chronic heart failure focus only on providing education related to risk factors and symptoms. Little information is available regarding the influence of physical functions, physical activity, and exercise self-efficacy on quality of life. This study was conducted to examine the impact of physical functioning, physical activity, and exercise self-efficacy on quality of life among individuals with chronic heart failure. This study used a cross-sectional descriptive design. Data were collected from 116 outpatients with chronic heart failure in Korea. Left ventricular ejection fraction and New York Heart Association classifications were chart reviewed. Information pertaining to levels of physical activity, exercise self-efficacy, and quality of life were collected using self-administered questionnaires. Data were analyzed using descriptive statistics, t tests, analyses of variance, correlations, and hierarchical multiple regressions. About 60% of participants were physically inactive, and most showed relatively low exercise self-efficacy. The mean quality-of-life score was 80.09. The significant correlates for quality of life were poverty, functional status, physical inactivity, and exercise self-efficacy. Collectively, these four variables accounted for 50% of the observed total variance in quality of life. Approaches that focus on enhancing exercise self-efficacy may improve patient-centered outcomes in those with chronic heart failure. In light of the low level of exercise self-efficacy reported and the demonstrated ability of this factor to predict quality of life, the development of effective strategies to enhance exercise self-efficacy offers a novel and effective approach to improving

    Parkinson's disease (PD) is characterized by the degeneration of dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc), resulting in motor and non-motor dysfunction. Physical exercise improves these symptoms in PD patients. To explore the molecular mechanisms underlying the beneficial effects of physical exercise, we exposed 1-methyl-4-phenyl-1,2,3,6-tetrahydropyrimidine (MPTP)-treated mice to a four-week physical exercise regimen, and subsequently explored their motor performance and the transcriptome of multiple PD-linked brain areas. MPTP reduced the number of DA neurons in the SNpc, whereas physical exercise improved beam walking, rotarod performance, and motor behavior in the open field. Further, enrichment analyses of the RNA-sequencing data revealed that in the MPTP-treated mice physical exercise predominantly modulated signaling cascades that are regulated by the top upstream regulators L-DOPA, RICTOR, CREB1, or bicuculline/dalfampridine, associated with movement disorders, mitochondrial dysfunction, and epilepsy-related processes. To elucidate the molecular pathways underlying these cascades, we integrated the proteins encoded by the exercise-induced differentially expressed mRNAs for each of the upstream regulators into a molecular landscape, for multiple key brain areas. Most notable was the opposite effect of physical exercise compared to previously reported effects of L-DOPA on the expression of mRNAs in the SN and the ventromedial striatum that are involved in-among other processes-circadian rhythm and signaling involving DA, neuropeptides, and endocannabinoids. Altogether, our findings suggest that physical exercise can improve motor function in PD and may, at the same time, counteract L-DOPA-mediated molecular mechanisms. Further, we hypothesize that physical exercise has the potential to improve non-motor symptoms of PD, some of which may be the result of (chronic) L-DOPA use.

    This study was conducted toward the objective of analyzing certain factors that influence physical activity in Spanish adolescent students using self-determination theory (Deci & Ryan, 1985; 2000) as a framework. Participants included 698 physical education students whose perception of the autonomy support provided by their teachers was assessed in and out of the class context. Also assessed were social goals of responsibility and relationship with others, basic psychological needs, and intrinsic motivation, which is part of self-determination theory (SDT). Finally, the "intention" factor posited by the theory of planned behavior (TPB) and students' rate of exercise in the last twelve months were considered. The results of structural equations modeling suggest autonomy education, autonomy support, and social goals positively predicted certain psychological mediators, which in turn positively predicted students' intrinsic motivation, which was a positive predictor of intention, and that of rate of exercise. The results also highlight the benefit of promoting autonomy to enhance students' physical exercise practice.

    Frailty is a state of vulnerability that involves an increased risk of adverse events and disability in older adults. It is a condition with a complex etiology and pathophysiology. Skeletal muscle power decreases earlier than muscle strength with advancing age and is more strongly associated with functional capacity than muscle strength in frail elderly populations. Multicomponent exercise programs, and especially resistance exercise that includes muscle power training, are currently the most relevant interventions to slow down disability and other adverse outcomes, even in the oldest-old. Moreover, these programs are valuable interventions in other frailty domains, such as falls and cognitive decline. Physical exercise, in the frail elderly, should be prescribed with a progressive individualized plan and just like other medical treatments. Copyright © 2014 SEGG. Published by Elsevier Espana.

    2017-09-23

    Abstract : Qigong is the meditative movement and therapeutic exercise of Eastern medicine. A growing body of evidence is validating its health benefits leading to mechanistic questions of how it works. The purpose of this article is to explore mechanisms of action related to Qigong, with the intent of unifying Eastern and Western exercise theory and to present a model for Qigong exercise analysis. Three exercises from a standardized Qigong form: 'Plucking the Stars', 'Lotus Leaves Rustle in the Wind', and 'Pacing Forwards and Backwards' were selected for meditative, energetic, and physical analyses. Meditative aspects include relaxation response, interoception and exteroception. Energetic aspects include stimulation of meridians through mental intent, acupressure, and self-massage. Physical aspects include flexibility, strength, articular stimulation, neuro-integration, respiratory effect, fascial stretch, visceral massage, balance challenge CranioSacral pump, lymphatic and venous return and glandular stimulation, and physiologic response to relaxation. Knowledge of mechanisms of action for specific Qigong exercises can guide operational definition of Qigong, selection of outcomes assessment in future research, inform prescriptive practice addressing clinical health issues, and advance adoption of Qigong practice within integrative health care. The model of analysis demonstrated in this discussion may assist in these endeavors.

    Full Text Available It is generally accepted that the aging process is associated with immunosenescence. On the other hand, physical activity has been consistently associated with positive states of affection and mood which also implies gains on psychological well-being. However, more studies are needed to support the benefit effect of exercise on specific population groups like the elderly. The purpose of the present work is to study the functional fitness, mood states and salivary IgA chronic adaptations after a physical exercise program. 28 subjects aged between 65 and 95 years old participated in this study. The experimental group exercised during 16 weeks, 3 times per week. The Wilcoxon test was used to compare the data. The results showed positive changes on the functional fitness that reinforce the trainability principle of the older person. The data shows also an improvement in mood states and chronic positive effects on salivary IgA after the exercise program.

    Full Text Available DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n2p233   In the past few years, increased popularity of resistance training (RT and a significant increase in the number of professionals and undergraduate in Physical Education students have been observed. A variety of names has been usually adopted for the same resistance exercise in fields. The aim of the study was to compare the resistance exercise nomenclature adopted by physical education professionals and students, and also to identify the frequencies of names adopted for these resistance exercises. The study included 191 graduate students and active physical education professionals of RT centers and gyms in the state of Rio de Janeiro, Brazil. Ten exercises traditionally performed on RT programs were selected. The results indicated that there was no association between the nomenclature of exercises and academic degree for all exercises included in the survey. However, there was significant difference (p <0.001 among response frequencies for each exercise, for the whole sample. In this sense, this study enabled identifying significant differences in the nomenclature of resistance exercises. Therefore, nomenclature standardization is essential to establish a direction and clearness in communication among professionals.

    Debate continues about the effect of 3, 4-methylenedioxymethamphetamine (MDMA) on cognitive and mitochondrial function through the CNS. It has been shown that physical exercise has an important protective effect on cellular damage and death. Therefore, we investigated the effect of physical exercise on MDMA-induced impairments of spatial learning and memory as well as MDMA effects on brain mitochondrial function in rats. Male wistar rats underwent short-term (2 weeks) or long-term (4 weeks) treadmill exercise. After completion of exercise duration, acquisition and retention of spatial memory were evaluated by Morris water maze (MWM) test. Rats were intraperitoneally (I.P) injected with MDMA (5, 10, and 15mg/kg) 30min before the first training trial in 4 training days of MWM. Different parameters of brain mitochondrial function were measured including the level of ROS production, mitochondrial membrane potential (MMP), mitochondrial swelling, mitochondrial outermembrane damage, the amount of cytochrome c release from the mitochondria, and ADP/ATP ratio. MDMA damaged the spatial learning and memory in a dose-dependent manner. Brain mitochondria isolated from the rats treated with MDMA showed significant increase in ROS formation, collapse of MMP, mitochondrial swelling, and outer membrane damage, cytochrome c release from the mitochondria, and finally increased ADP/ATP ratio. This study also found that physical exercise significantly decreased the MDMA-induced impairments of spatial learning and memory and also mitochondrial dysfunction. The results indicated that MDMA-induced neurotoxicity leads to brain mitochondrial dysfunction and subsequent oxidative stress is followed by cognitive impairments. However, physical exercise could reduce these deleterious effects of MDMA through protective effects on brain mitochondrial function. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Exercise and physical activity are constantly gaining attention as adjuvant treatment for substance use disorders, supplementing classical pharmacological and psychotherapeutic approaches. The present work reviews studies addressing the therapeutic effects of exercise in alcohol abuse/dependence, nicotine abuse/dependence, and illicit drug abuse/dependence. In the field of smoking cessation, evidence is strong for exercise as an effective adjuvant treatment, whereas no generalizable and methodologically strong studies have been published for alcohol and drug treatment so far, allowing only preliminary conclusions about the effectiveness of exercise in these disorders. A couple of potential mechanisms are discussed, by which exercise may act as an effective treatment, as well as future directions for studies investigating exercise as a treatment strategy for substance use disorders.

    Statin treatment in association with physical exercise practice can substantially reduce cardiovascular mortality risk of dyslipidemic individuals, but this practice is associated with myopathic event exacerbation. This study aimed to present the most recent results of specific literature about the effects of statins and its association with physical exercise on skeletal musculature. Thus, a literature review was performed using PubMed and SciELO databases, through the combination of the keywords "statin" AND "exercise" AND "muscle", restricting the selection to original studies published between January 1990 and November 2013. Sixteen studies evaluating the effects of statins in association with acute or chronic exercises on skeletal muscle were analyzed. Study results indicate that athletes using statins can experience deleterious effects on skeletal muscle, as the exacerbation of skeletal muscle injuries are more frequent with intense training or acute eccentric and strenuous exercises. Moderate physical training, in turn, when associated to statins does not increase creatine kinase levels or pain reports, but improves muscle and metabolic functions as a consequence of training. Therefore, it is suggested that dyslipidemic patients undergoing statin treatment should be exposed to moderate aerobic training in combination to resistance exercises three times a week, and the provision of physical training prior to drug administration is desirable, whenever possible.

  20. The effects of stress on physical activity and exercise.

    Psychological stress and physical activity (PA) are believed to be reciprocally related; however, most research examining the relationship between these constructs is devoted to the study of exercise and/or PA as an instrument to mitigate distress. The aim of this paper was to review the literature investigating the influence of stress on indicators of PA and exercise. A systematic search of Web of Science, PubMed, and SPORTDiscus was employed to find all relevant studies focusing on human participants. Search terms included "stress", "exercise", and "physical activity". A rating scale (0-9) modified for this study was utilized to assess the quality of all studies with multiple time points. The literature search found 168 studies that examined the influence of stress on PA. Studies varied widely in their theoretical orientation and included perceived stress, distress, life events, job strain, role strain, and work-family conflict but not lifetime cumulative adversity. To more clearly address the question, prospective studies (n = 55) were considered for further review, the majority of which indicated that psychological stress predicts less PA (behavioral inhibition) and/or exercise or more sedentary behavior (76.4 %). Both objective (i.e., life events) and subjective (i.e., distress) measures of stress related to reduced PA. Prospective studies investigating the effects of objective markers of stress nearly all agreed (six of seven studies) that stress has a negative effect on PA. This was true for research examining (a) PA at periods of objectively varying levels of stress (i.e., final examinations vs. a control time point) and (b) chronically stressed populations (e.g., caregivers, parents of children with a cancer diagnosis) that were less likely to be active than controls over time. Studies examining older adults (>50 years), cohorts with both men and women, and larger sample sizes (n > 100) were more likely to show an inverse association. 85.7 % of higher

    Data are limited regarding effect of intensity of leisure-time physical activity on metabolic syndrome. Furthermore, no prospective data are available regarding effect of occupational and commuting physical activity on metabolic syndrome. We compared metabolic syndrome risk by intensity level of leisure-time exercise and by occupational and commuting physical activity in Japanese workers. We followed 22,383 participants, aged 30-64 years, without metabolic syndrome until 2014 March (maximum, 5 years of follow-up). Physical activity was self-reported. Metabolic syndrome was defined by the Joint Statement criteria. We used Cox regression models to estimate the hazard ratios (HRs) and 95 % confidence intervals (CIs) of metabolic syndrome. During a mean follow-up of 4.1 years, 5361 workers developed metabolic syndrome. After adjustment for covariates, compared with engaging in no exercise, the HRs (95 % CIs) for metabolic equivalent hours of exercise per week were 0.99 (0.90, 1.08), 0.99 (0.90, 1.10), and 0.95 (0.83, 1.08), respectively, among individuals engaging in moderate-intensity exercise alone; 0.93 (0.75, 1.14), 0.81 (0.64, 1.02), and 0.84 (0.66, 1.06), among individuals engaging in vigorous-intensity exercise alone; and 0.90 (0.70, 1.17), 0.74 (0.62, 0.89), and 0.81 (0.69, 0.96) among individuals engaging in the two intensities. Higher occupational physical activity was weakly but significantly associated with lower risk of metabolic syndrome. Walking to and from work was not associated with metabolic syndrome. Vigorous-intensity exercise alone or vigorous-intensity combined with moderate-intensity exercise and worksite intervention for physical activity may help prevent metabolic syndrome for Japanese workers.

    Full Text Available Abstract Aims This study evaluated the possible barriers to the permanence of physical exercise (PE of old women. Methods The study population comprised 61 old women participants for at least one year of a supervised PE program, who underwent anamnesis, and applied the Barriers Questionnaire to Physical Activity Practice in the Elderly (QBPAFI. Exploratory factorial analysis was used to evaluate QBPAFI data. The analysis of principal component was applied to the 22 questions through orthogonal rotation to analyze the correlation between the questions. The Kaiser-Meyer-Olkin test was applied to evaluate the suitability of the sample size, and the Bartlett's test to assess whether the original matrix correlation is an identity matrix. Eigenvalues greater than 1 were considered for analysis. Results The motivational factor was the major determinant of perceived barriers (43.3%, followed by psychosocial (12.29%, facilities and appearance (8.75%, and exercise conditions (8.10% factors. Conclusion Knowing the benefits of physical activity, and the main barriers that prevent the permanence of active old people to physical exercise programs, new strategies must be taken to increase the rate of adherence of this group.

    Physical exercise is considered to be one of the beneficial factors of a proper lifestyle and is nowadays seen as an indispensable element for good health, able to lower the risk of disorders of the cardiovascular, endocrine and osteomuscular apparatus, immune system diseases and the onset of potential neoplasms. A moderate and programmed physical exercise has often been reported to be therapeutic both in the adulthood and in aging, since capable to promote fitness. Regular exercise alleviates the negative effects caused by free radicals and offers many health benefits, including reduced risk of all-cause mortality, sarcopenia in the skeletal muscle, chronic disease, and premature death in elderly people. However, physical performance is also known to induce oxidative stress, inflammation, and muscle fatigue. Many efforts have been carried out to identify micronutrients and natural compounds, also known as nutraceuticals, able to prevent or attenuate the exercise-induced oxidative stress and inflammation. The aim of this review is to discuss the benefits deriving from a constant physical activity and by the intake of antioxidant compounds to protect the body from oxidative stress. The attention will be focused mainly on three natural antioxidants, which are quercetin, resveratrol and curcumin. Their properties and activity will be described, as well as their benefits on physical activity and on aging, which is expected to increase through the years and can get favorable benefits from a constant exercise activity.

    Since the work of Eriksson and Lindgärde, published over two decades ago (Diabetologia 1991;34:891-898), we have known that type 2 diabetes can be prevented or delayed by supervised lifestyle interventions (physical exercise and diet modification) in persons at risk of the disease. Here we discuss a novel, time-efficient approach to physical exercise prescription, low-volume, high-intensity interval training (LVHIT), and its efficacy for inducing a range of health benefits in a variety of populations at risk of inactivity-related diseases. We look to the future and suggest that current guidelines for exercise may need to be revised to include different training techniques to deliver the optimum exercise prescription. Indeed, we predict that subsequent exercise guidelines will include LVHIT as part of a comprehensive 'fitness menu' that allows individuals to select the exercise regimen that best fulfils their medical needs, is suited to their lifestyle and daily time restraints, and meets their personal goals.

  5. The Pleiotropic Effect of Physical Exercise on Mitochondrial Dynamics in Aging Skeletal Muscle

    Full Text Available Decline in human muscle mass and strength (sarcopenia is one of the principal hallmarks of the aging process. Regular physical exercise and training programs are certain powerful stimuli to attenuate the physiological skeletal muscle alterations occurring during aging and contribute to promote health and well-being. Although the series of events that led to these muscle adaptations are poorly understood, the mechanisms that regulate these processes involve the “quality” of skeletal muscle mitochondria. Aerobic/endurance exercise helps to maintain and improve cardiovascular fitness and respiratory function, whereas strength/resistance-exercise programs increase muscle strength, power development, and function. Due to the different effect of both exercises in improving mitochondrial content and quality, in terms of biogenesis, dynamics, turnover, and genotype, combined physical activity programs should be individually prescribed to maximize the antiaging effects of exercise.

    While workplace physical exercise can help manage musculoskeletal disorders, less is known about psychosocial effects of such interventions. This aim of this study was to investigate the effect of workplace physical exercise on psychosocial factors among workers with chronic musculoskeletal pain.The trial design was a 2-armed parallel-group randomized controlled trial with allocation concealment. A total of 66 slaughterhouse workers (51 men and 15 women, mean age 45 years [standard deviation (SD) 10]) with upper limb chronic musculoskeletal pain were randomly allocated to group-based strength training (physical exercise group) or individual ergonomic training and education (reference group) for 10 weeks. Social climate was assessed with the General Nordic Questionnaire for Psychological and Social Factors at Work, and vitality and mental health were assessed with the 36-item Short Form Health Survey. All scales were converted to 0 to 100 (higher scores are better). Between-group differences from baseline to follow-up were determined using linear mixed models adjusted for workplace, age, gender, and baseline values of the outcome.Mean baseline scores of social climate, mental health, and vitality were 52.2 (SD 14.9), 79.5 (SD 13.7), and 53.9 (SD 19.7), respectively. Complete baseline and follow-up data were obtained from 30 and 31 from the physical exercise and reference groups, respectively. The between-group differences from baseline to follow-up between physical exercise and reference were 7.6 (95% CI 0.3 to 14.9), -2.3 (95% CI -10.3 to 5.8), and 10.1 (95% CI 0.6 to 19.5) for social climate, mental health, and vitality, respectively. For social climate and vitality, this corresponded to moderate effect sizes (Cohen d = 0.51 for both) in favor of physical exercise. There were no reported adverse events.In conclusion, workplace physical exercise performed together with colleagues improves social climate and vitality among workers with chronic musculoskeletal

    The Integrated Support Center for Nuclear Nonproliferation and Nuclear Security (ISCN) of the Japan Atomic Energy Agency set up exercise facilities for trainee of nuclear power emerging countries in Asia involved in Physical Protection (PP) including government officers in charge of nuclear security policy or nuclear security regulation, planning and management staff of PP facilities of operating companies, design professionals for PP facilities, and security personnel responsible for PP. After April in 2012, the facility started to be applied to actual ISCN's PP training and is expected as training field for not only Asian nuclear emerging country but also domestic nuclear energy companies and regulatory bodies. In order to provide effective and practical exercises, we set up the training facilities with basic measures and equipment typical of those used in actual PP facilities, e.g., protective fences, sensors, and cameras. This paper provides an outline of the facilities. (author)

    The effect of oxidative stress on muscle damage inducted by physical exercise is widely debated. It is generally agreed that endurance and intense exercise can increase oxidative stress and generate changes in antioxidant power inducing muscle damage; however, regular and moderate exercise can be beneficial for the health improving the antioxidant defense mechanisms in the majority of cases. Growing evidences suggest that an increased oxidative/nitrosative stress is involved in the pathogenesis of several muscular dystrophies (MDs). Notably, physical training has been considered useful for patients with these disorders. This review will focus on the involvement of oxidative stress in MDs and on the possible effects of physical activities to decrease oxidative damage and improve motor functions in MDs patients.

    A increased number of eating disorders among teen-agers are currently being reported. Physical exercise, especially when done individually, is one of the methods chosen for losing weight. We are basing this study on the hypothesis of a larger number of eating habit disorders (EHD's) in subjects who do physical exercise alone. This study describes and compares eating habits among teen-agers that do individual exercise as opposed to athletes who work out in groups or on teams. Cross-section study of 532 teen-agers ages 14-18 who are enrolled in school and who do physical exercise, having been selected at random by means of a two-stage, stratified sampling process. The subjects were divided into two groups according whether they did individual physical exercise alone (Number: 216) or in groups (Number: 316). The eating habits of both groups were analyzed based on a questionnaire filled out by the subjects themselves. In the group preferring individual sports, females were predominant (degree of males 0.44). Of these females, their being on diets in order to lose weight was 3.12 times more frequent, compulsive eating episodes being 3.73 times more frequent. As regards behaviors which might be considered to be compensatory, there is a clear concentration thereof among those who do sports individually, hence 43% stated to voluntarily undergo periods of fasting (4.96 times more than those who exercise in groups), 46% stating to have brought on vomiting at one time or another for "dieting" purposes (3.76 more) and up to 26% have used laxatives with the intention of losing weight (2.56 times more than among athletes who play on teams). The existence of EHD's seems to be associated with teen-agers who play individual sports as opposed to those who play on teams.

    The demand of power is increasing day by day due to the increase of world population as well as the industrialization and modernization. Depletion of the world's fossil fuel reserves and the adverse effects of their uses on the environment insist the researchers to find out some means of efficient and cost effective alternative energy sources from small to large scales. In a gymnasium the human metabolism power is used to drive the physical exercise devices. However there are a number of exercise device which can have the potential to generate electricity during physical exercise. By converting the available mechanical energy from these exercise devices into kinetic energy, electric power can be produced. In this work, energy was harvested from the most commonly used physical exercise devices used in the gymnasium - paddling and chin up. The paddle pulley and the chin up pulley were connected to the couple pulley which in turn coupled to an alternator by a V-belt to produce electrical energy and a rechargeable battery was used to store electrical energy. The power generation from the device depends upon the speed at which the alternator runs and the age limit. The electrical energy output was observed 83.6 watt at 1300 rpm and 62.5 watt at1150 rpm alternator speed for the paddling and chin up respectively recorded for an average adult. The device was designed for a constant 49N load on the alternator for both paddling and chin up operation. By running each of these devices for about 12 hours in a day, any gymnasium can avoid burning of almost 23.67 kg and 31.6 kg of diesel fuel per year for chin up and paddling respectively. Also it can cut off the CO2 emission to the environment which reveals itself a standalone green micro gym.

    Exercise is a key component of the management of ankylosing spondylitis (AS). Despite numerous benefits, compliance with exercise programs is low. Little attention has been accorded to the experiences of individuals with AS toward physical activity (PA). This study aimed to explore the attitudes toward PA and exercise of adults with AS. A qualitative descriptive design using thematic analysis was used. Seventeen adults with AS participated in individual, semistructured interviews. Interviews were recorded, transcribed, coded and analyzed for themes and subthemes. Four themes emerged from the analysis: (1) benefits, (2) barriers, (3) motivation, and (4) strategies and enablers. Benefits included amelioration of symptoms, improvements in general health, and enhancement of quality of life. Subthemes of barriers to PA included lack of resources, negative attitudes to exercise, misinformation, and condition-related factors. Motivation to exercise was influenced by intrinsic and extrinsic factors. Participants proposed strategies to enhance PA participation and exercise engagement. Awareness of the benefits of PA appears insufficient to motivate individuals with AS to exercise; a number of factors influence individual motivation to exercise. Many perceived barriers to PA may be considered modifiable. Individually-tailored interventions, collaboratively developed by the individual and the healthcare professionals, were proposed as strategies for effective PA and exercise prescription.

    Decreased sleep duration and altered sleep quality are risk factors for obesity in youth. Structured exercise training has been shown to increase sleep duration and improve sleep quality. This study aimed at evaluating the impact of exercise training for improving sleep duration, sleep quality and physical activity in obese adolescents (OB). Twenty OB (age: 14.5 ± 1.5 years; body mass index: 34.0 ± 4.7 kg m(-2) ) and 20 healthy-weight adolescents (HW) completed an overnight polysomnography and wore an accelerometer (SenseWear Bodymedia) for 7 days. OB participated in a 12-week supervised exercise-training programme consisting of 180 min of exercise weekly. Exercise training was a combination of aerobic exercise and resistance training. Sleep duration was greater in HW compared with OB (P < 0.05). OB presented higher apnoea-hypopnoea index than HW (P < 0.05). Physical activity (average daily metabolic equivalent of tasks [METs]) by accelerometer was lower in OB (P < 0.05). After exercise training, obese adolescents increased their sleep duration (+64.4 min; effect size: 0.88; P = 0.025) and sleep efficiency (+7.6%; effect size: 0.76; P = 0.028). Physical activity levels were increased in OB as evidenced by increased steps per day and average daily METs (P < 0.05). Improved sleep duration was associated with improved average daily METs (r = 0.48, P = 0.04). The present study confirms altered sleep duration and quality in OB.

    2013-01-01

    Background Psychological stress and physical activity (PA) are believed to be reciprocally related; however, most research examining the relationship between these constructs is devoted to the study of exercise and/or PA as an instrument to mitigate distress. Objective The aim of this paper was to review the literature investigating the influence of stress on indicators of PA and exercise. Methods A systematic search of Web of Science, Pub-Med, and SPORTDiscus was employed to find all relevant studies focusing on human participants. Search terms included “stress”, “exercise”, and “physical activity”. A rating scale (0–9) modified for this study was utilized to assess the quality of all studies with multiple time points. Results The literature search found 168 studies that examined the influence of stress on PA. Studies varied widely in their theoretical orientation and included perceived stress, distress, life events, job strain, role strain, and work–family conflict but not lifetime cumulative adversity. To more clearly address the question, prospective studies (n = 55) were considered for further review, the majority of which indicated that psychological stress predicts less PA (behavioral inhibition) and/or exercise or more sedentary behavior (76.4 %). Both objective (i.e., life events) and subjective (i.e., distress) measures of stress related to reduced PA. Prospective studies investigating the effects of objective markers of stress nearly all agreed (six of seven studies) that stress has a negative effect on PA. This was true for research examining (a) PA at periods of objectively varying levels of stress (i.e., final examinations vs. a control time point) and (b) chronically stressed populations (e.g., caregivers, parents of children with a cancer diagnosis) that were less likely to be active than controls over time. Studies examining older adults (>50 years), cohorts with both men and women, and larger sample sizes (n > 100) were more likely

    MicroRNAs are small, non-coding molecules with a crucial function in the cell´s biologic regulation. Circulating levels of miRNAs may be useful biomarkers in metabolic diseases such as type 2 Diabetes Mellitus (DM2), which alters the circulating concentrations of several types of miRNA. Specific serum profiles of these molecules have been identified in high-risk patients before the development of DM2 and its chronic complications. Most importantly, these profiles can be modified with physical exercise, which is crucial in the treatment of metabolic diseases. Acute physical activity alone can induce changes in tissue specific miRNAs, and responses are different in aerobic or non-aerobic training. Muscle and cardiovascular miRNAs, which may play an important role in the adap tation to exercise, are predominantly altered. Even further, there is a correlation between serum levels of miRNAs and fitness, suggesting a role for chronic exercise in their regulation. Thus, miRNAs are molecules of growing importance in exercise physiology, and may be involved in the mechanisms behind the beneficial effects of physical activity for patients with metabolic diseases.

    Methadone-maintained persons are at increased risk for many physical and mental health disorders compared to the general population. Increased physical activity could offset these risks. We assessed physical activity level, and perceived benefits and barriers to exercise in a group of 305 methadone-maintained smokers. Mean participant age was 39.9 years, 50.2% were male, 79.7% were non-Hispanic White, and mean body mass index was 29.8. Nearly 45% endorsed fair or poor physical health. Although participants perceived many benefits of exercise and few barriers, only 38% of participants met weekly recommendations for physical activity, and nearly 25% reported no physical activity. Those who met recommended guidelines were significantly more likely to endorse relapse prevention as a benefit of exercise. Motivating MMT patients to increase physical activity could have important physical, mental health, and drug treatment benefits. Copyright © 2013 Elsevier Inc. All rights reserved.

    This study, theoretically based on the Exercise Self-Esteem Model, EXSEM, examined effects of exercise modality on physical and global self-esteem (PSE, GSE) in breast cancer survivors. The EXSEM posits GSE at the apex with PSE feeding into GSE. PSE has three subdomains: physical condition (PC), attractive body (AB), and physical strength (PS). The goals were to compare the effect of combination modality versus single-modality exercise on PSE and GSE and to explore the relationship between exercise modality and the subdomains of PSE. Survivors were randomly allocated to flexibility (F), aerobic (A), resistance (R), or aerobic plus resistance (AR), 12-wk, individualized, home-based exercise program. Pre/posttesting included submaximal treadmill test, six-repetition maximum chest press and leg press, YMCA bench press, shoulder/hip flexibility, and bioelectric impedance analysis body composition. Esteem measures were the Physical Self-Perception Profile and the Rosenberg Self-Esteem Scale. Forty-two women completed the study (F = 12, A = 10, R = 9, and AR = 11). Fitness improvements congruent with exercise modality were seen in all groups. PSE and GSE outcomes did not reveal a greater effect from the combination modality program, AR, compared with the single-modality programs A and R. The relationships between the single-modality groups and the subdomains of PC, PS, and AB were supported in the R group (PS and AB increased) and were partially supported in the A group (PC, not AB, increased). A single-modality R program significantly improved all domains of PSE, and participation in the A program improved the PC subdomain. The combination exercise program did not enhance PSE greater than the single-modality programs. EXSEM was a useful framework for exploring esteem in breast cancer survivors.

    To assess exercise behavior and physical activity levels after open heart surgery. This prospective cohort study included 130 patients (70.8% male, aged 61.0 ± 12.2 years, 53.8% coronary bypass grafting) who underwent open heart surgery. The exercise behavior and physical activity of these patients were assessed at the 3- and 6-month follow-up appointments. Additional interviews were also conducted to further assess exercise behavior. Physical activity duration and metabolic equivalents were calculated from self-reported questionnaire responses. Moreover, possible related demographic factors, clinical features, participation in cardiac rehabilitation programs, and physical activity levels were additionally evaluated. Six months after hospital discharge, most patients were in the action (39.2%) and maintenance (37.7%) stages. Other subjects were in the precontemplation (11.5%), contemplation (5.4%), and preparation (6.2%) stages. The average physical activity level was 332.6 ± 377.1 min/week and 1198.1 ± 1396.9 KJ/week. Subjects in the action and maintenance stages exercised an average of 399.4 ± 397.6 min/week, significantly longer than those in other stages (116.2 ± 176.2 min/week, p = 0.02). Subjects that participated in outpatient cardiac rehabilitation programs after discharge may have the better exercise habit. Gender had no significant effect on exercise behavior 6 months after hospital discharge. Most subjects following open heart surgery may maintain regular exercise behavior at 6 months after hospital discharge. Physical activity levels sufficient for cardiac health were achieved by subjects in the active and maintenance stages. Outpatient cardiac rehabilitation programs are valuable for encouraging exercise behavior after heart surgery. Exercise behavior; Open heart surgery; Physical activity; Transtheoretical model.

    Full Text Available Physical exercise has shown positive effects on symptomatology and on the reduction of comorbidities in population with autism spectrum disorder (ASD. However, there is still no consensus about the most appropriate exercise intervention model for children with ASD. The physical exercise program for children with autism (PEP-Aut protocol designed allow us to (i examine the multivariate associations between ASD symptoms, metabolic profile, physical activity level, physical fitness, and health-related quality of life of children with ASD; (ii assess the effects of a 40-week exercise program on all these aspects of children with ASD. The impact of the exercise program will be assessed based on the sequence of the two phases. Phase 1 is a 12-week cross-sectional study assessing the symptomatology, metabolic profile, physical fitness and physical activity levels, socioeconomic status profile, and health-related quality of life of participants. This phase is the baseline of the following phase. Phase 2 is a 48-week intervention study with a 40-week intervention with exercise that will take place in a specialized center for children with ASD in the city of Maceió-Alagoas, Brazil. The primary outcomes will be change in the symptomatic profile and the level of physical activity of children. Secondary outcomes will be anthropometric and metabolic profiles, aerobic function, grip strength, socioeconomic status, and health-related quality of life. The study will provide critical information on the efficacy of exercise for children with ASD and help guide design and delivery of future programs.

    Exercise and physical activity play an important role in physical frailty, but we do not know if they are markers, components and/or correlates of this syndrome. The purpose of this paper is briefly to discuss the potential roles played by physical activity and exercise on the development and progression of frailty, and to propose directions for future research in this field. Exercise practice lowers the levels of some frailty markers, such as tumor necrosis factor-alpha, interleukin-6, C-reactive protein, and uric acid, and also resistance to insulin. The influence of exercise on the main frailty domains is also well established in the literature. Exercise improves muscle strength, gait speed, cognition (particularly executive control related-tasks), weight maintenance, mood and, to a lesser extent, feelings of energy. Although exercise and physical activity positively influence the main frailty markers and domains, most findings were obtained for other elderly populations (e.g., healthy elderly, clinical populations). For future research, efforts must be made to define some key concepts (exercise or physical activity) in selecting study samples and in establishing intervention length. Attention must also be paid to identifying the most efficacious exercise interventions regarding type, frequency, intensity and session duration, and approaching a dose-response relationship between a physically active life-style and frailty. Thus, further research, especially longitudinal randomized controlled trials, is needed to understand the role of physical activity and exercise in the frailty syndrome.

    INTRODUCTION Although the benefits of physical activity and exercise are widely acknowledged, many middle-aged and elderly individuals remain sedentary. This cross-sectional study aimed to identify the external and internal barriers to physical activity and exercise participation among middle-aged and elderly individuals, as well as identify any differences in these barriers between the two groups. METHODS Recruited individuals were categorised into either the middle-aged (age 45-59 years, n = 60) or elderly (age ≥ 60 years, n = 60) group. Data on demographics, anthropometry, as well as external and internal barriers to participation in physical activity and exercise were collected. RESULTS Analysis showed no significant differences in the total scores of all internal barriers between the two groups (p > 0.05). The total scores for most external barriers between the two groups also showed no significant differences (p > 0.05); only 'cost' (p = 0.045) and 'exercise interferes with social/family activities' (p = 0.011) showed significant differences. The most common external barriers among the middle-aged and elderly respondents were 'not enough time' (46.7% vs. 48.4%), 'no one to exercise with' (40.0% vs. 28.3%) and 'lack of facilities' (33.4% vs. 35.0%). The most common internal barriers for middle-aged respondents were 'too tired' (48.3%), 'already active enough' (38.3%), 'do not know how to do it' (36.7%) and 'too lazy' (36.7%), while those for elderly respondents were 'too tired' (51.7%), 'lack of motivation' (38.4%) and 'already active enough' (38.4%). CONCLUSION Middle-aged and elderly respondents presented with similar external and internal barriers to physical activity and exercise participation. These factors should be taken into account when healthcare policies are being designed and when interventions such as the provision of facilities to promote physical activity and exercise among older people are being considered.

    Full Text Available Regarding the increasing prevalence of cardiovascular disease (CVD especially myocardial infarction (MI, and the insufficiency of information in the field of physical rehabilitation, this study aimed to investigate the effectiveness of a course of physical rehabilitation on the psychological status and physical characteristics f cardiac patients. In this study, the effect of 8 weeks exercise training, 3 sessions of 45 minutes duration per week, on the physical and psychological function of MI patients was evaluated. Eighty patients who were referred to the rehabilitation unit of Isfahan cardiovascular Research Center were randomly divided into two groups of exercise and non-exercise. The data of pre and post exercise course were analyzed with the SPSS software using the two-sample t-test and multiple liner regression. The comparison of the mean changes of functional capacity. Weight, body mass index (BMI, heart rate, and systolic and diastolic blood pressures between exercise and non-exercise groups after 8 weeks showed significant difference for all studied factors (P<0.05. Also, investigating the psychological characteristics such as depression, anxiety and hostility scores indicated a significant change after exercise training (P<0.05. Personality and behavior showed no significant difference. This study suggests the functional has a significant effect on improving the function capacity and psychological behavior in post MI patients.

    Rheumatoid arthritis (RA) is an autoimmune disease, which not only affects the joints but can also impact on general well-being and risk for cardiovascular disease. Regular physical activity and exercise in patients with RA have numerous health benefits. Nevertheless, the majority of patients with RA are physically inactive. This indicates that people with RA might experience additional or more severe barriers to physical activity or exercise than the general population. This narrative review provides an overview of perceived barriers, benefits and facilitators of physical activity and exercise in RA. Databases were searched for articles published until September 2014 using the terms 'rheumatoid arthritis', 'physical activity', 'exercise', 'barriers', 'facilitators', 'benefits', 'motivation', 'motivators' and 'enablers'. Similarities were found between disease-specific barriers and benefits of physical activity and exercise, e.g. pain and fatigue are frequently mentioned as barriers, but reductions in pain and fatigue are perceived benefits of physical activity and exercise. Even though exercise does not influence the existence of barriers, physically active patients appear to be more capable of overcoming them. Therefore, exercise programmes should enhance self-efficacy for exercise in order to achieve long-term physical activity and exercise behaviour. Encouragement from health professionals and friends/family are facilitators for physical activity and exercise. There is a need for interventions that support RA patients in overcoming barriers to physical activity and exercise and help sustain this important health behaviour.

    Motor planning in older adults likely relies on the overengagement of the prefrontal cortex (PFC) and is associated with slowness of movement and responses. Does a physically active lifestyle counteract the overrecruitment of the PFC during action preparation? This study used high-resolution electroencephalography to measure the effect of physical exercise on the executive functions of the PFC preceding a visuomotor discriminative task. A total of 130 participants aged 15-86 were divided into two groups based on physical exercise participation. The response times and accuracy and the premotor activity of the PFC were separately correlated with age for the two groups. The data were first fit with a linear function and then a higher order polynomial function. We observed that after 35-40 years of age, physically active individuals have faster response times than their less active peers and showed no signs of PFC hyperactivity during motor planning. The present findings show that physical exercise could speed up the response of older people and reveal that also in middle-aged people, moderate-to-high levels of physical exercise benefits the planning/execution of a response and the executive functions mediated by the PFC, counteracting the neural overactivity often observed in the elderly adults.

    Physical exercise has positive effects on cognitive function in elderly people. It is unknown, however, if combinations of non-pharmaceutical interventions can produce more benefits than single ones. This study aimed to identify if physical exercise combined with music improves cognitive function in normal elderly people more than exercise alone. We enrolled 119 subjects (age 65-84 years old). Forty subjects performed physical exercise (once a week for an hour with professional trainers) with musical accompaniment (ExM group), developed by YAMAHA Music Foundation; 40 subjects performed the same exercise without music (Ex group); 39 subjects were the control group (Cont group). Before and after the year-long intervention, each patient was assessed by neuropsychological batteries. MRIs were performed before and after intervention; the Voxel-based Specific Regional analysis system for Alzheimer's Disease (VSRAD) was used to assess medial temporal lobe atrophy. Analysis of variance (ANOVA) was significant only in visuospatial function. The multiple comparison (ExM vs. Ex, ExM vs. Cont, Ex vs. Cont) was significant between the ExM and Cont group. Intra-group analyses before and after intervention revealed significant improvement in visuospatial function in the ExM group, and significant improvements in other batteries in all three groups. The VSRAD score significantly worsened in the ExM and Ex groups. Physical exercise combined with music produced more positive effects on cognitive function in elderly people than exercise alone. We attributed this improvement to the multifaceted nature of combining physical exercise with music, which can act simultaneously as both cognitive and physical training.

    Statin treatment in association with physical exercise practice can substantially reduce cardiovascular mortality risk of dyslipidemic individuals, but this practice is associated with myopathic event exacerbation. This study aimed to present the most recent results of specific literature about the effects of statins and its association with physical exercise on skeletal musculature. Thus, a literature review was performed using PubMed and SciELO databases, through the combination of the keywords “statin” AND “exercise” AND “muscle”, restricting the selection to original studies published between January 1990 and November 2013. Sixteen studies evaluating the effects of statins in association with acute or chronic exercises on skeletal muscle were analyzed. Study results indicate that athletes using statins can experience deleterious effects on skeletal muscle, as the exacerbation of skeletal muscle injuries are more frequent with intense training or acute eccentric and strenuous exercises. Moderate physical training, in turn, when associated to statins does not increase creatine kinase levels or pain reports, but improves muscle and metabolic functions as a consequence of training. Therefore, it is suggested that dyslipidemic patients undergoing statin treatment should be exposed to moderate aerobic training in combination to resistance exercises three times a week, and the provision of physical training prior to drug administration is desirable, whenever possible.

    The objective of this study was to examine the mechanisms by which physical activity affects the menstrual cycle. Women with high, medium, and low levels of physical activity were compared for menstrual function, physical characteristics, and urinary and serum levels of luteinizing hormone, follicle-stimulating hormone, prolactin, estradiol-17 beta, and 2-hydroxyestrone. None of the physical characteristics other than age and muscle area were significantly different in the three groups. The percentage of body fat did not appear to be a factor in the amenorrhea induced by strenuous exercise, as the percent of body fat in all three groups was less than 22%. The group of athletes under strenuous exercise which correlated with oligomenorrhea had decreased serum levels of luteinizing hormone, prolactin, and estradiol-17 beta but elevated levels of 2-hydroxyestrone. These data suggest that anovulatory cycles are correlated with the amount of exercise and increased levels of catechol estrogens. Catecholamines and beta-endorphin elevated by exercise may interact to suppress luteinizing hormone release at the hypothalamic pituitary axis.

    The purpose of the study was to evaluate the effects of a Social Cognitive Theory-based intervention designed to increase the frequency of leisure time planned moderate and vigorous physical exercise among rural high school students attending physical education class. Students in treatment and comparison groups were exposed to an activity-based physical education curricula. The treatment group received eight behavioral skill-building lessons integrated into the existing curriculum. The Social Cognitive Theory-based educational treatment increased levels of moderate physical exercise occurring outside the classroom. This study demonstrated an impact on adolescent leisure time moderate physical exercise using classroom instruction. The intervention was most effective with students who were previously sedentary. The curricular approaches used to promote regular moderate exercise may be useful for sedentary adolescents.

    Research on effects of acute physical exercise on performance in a concurrent cognitive task has generated equivocal evidence. Processing efficiency theory predicts that concurrent physical exercise can increase resource requirements for sustaining cognitive performance even when the level of performance is unaffected. This hypothesis was tested in a dual-task experiment. Sixty young adults worked on a primary auditory attention task and a secondary interval production task while cycling on a bicycle ergometer. Physical load (cycling) and cognitive load of the primary task were manipulated. Neither physical nor cognitive load affected primary task performance, but both factors interacted on secondary task performance. Sustaining primary task performance under increased physical and/or cognitive load increased resource consumption as indicated by decreased secondary task performance. Results demonstrated that physical exercise effects on cognition might be underestimated when only single task performance is the focus.

    Due to medical advances, most children with congenital heart disease (CHD) are expected to survive into adulthood. Establishing adequate physical self-concept and cardiopulmonary tolerance during the adolescent period can primarily enhance overall well-being. The purpose of this study was to undertake a gender-specific evaluation of the domain of physical self-concept among adolescents with mild CHD, and to examine the relationships between physical self-concept and cardiopulmonary exercise tolerance among adolescents with mild CHD. Four hundred and thirteen adolescents 12-20 years of age, whose cardiologists had not recommended any limitation of exercise, completed Physical Self-Description Questionnaires and three-minute step tests in two outpatient cardiology departments. The male participants had significantly greater scores in measures of overall physical self-concept, competence in sports, physical appearance, body fat, physical activity, endurance, and strength than did the female participants. More than 80% of the participants had at least an average cardiopulmonary exercise tolerance index. The perception of not being 'too fat' and being more physically active were significant correlates of better cardiopulmonary exercise tolerance for adolescents with mild CHD. The results provided evidence for gender-specific evaluation of domains of physical self-concept among adolescents with mild CHD. The three-minute step test to measure cardiopulmonary exercise tolerance in adolescents with mild CHD may be an appropriate objective measure for use in future research. Continued efforts are needed in early intervention to promote cardiopulmonary exercise tolerance. © The European Society of Cardiology 2014.

    Increasing physical activity is a goal of Healthy People 2010. Although the health benefits of physical activity are documented, older adults are less physically active than any other age group. The purpose of this study was to examine barriers and facilitators to physical activity and exercise among underserved, ethnically diverse older adults. Seventy-one older adults were recruited through community agencies to participate in seven ethnic-specific focus groups: American Indian/Alaska Native, African American, Filipino, Chinese, Latino, Korean, and Vietnamese. Groups were conducted in the participants' primary language and ranged in size from 7-13 participants. Mean age was 71.6 years (range from 52 to 85 years; SD +/- 7.39). Professional translators transcribed audiotapes into the language of the group and then translated the transcript into English. Transcripts were systematically reviewed using content analysis. Suggested features of physical activity programs to enhance participation among ethnically diverse minority older adults included fostering relationships among participants; providing culture-specific exercise; offering programs at residential sites; partnering with and offering classes prior to or after social service programs; educating families about the importance of physical activity for older adults and ways they could help; offering low- or no-cost classes; and involving older adults in program development. Walking was the exercise of choice across all ethnic groups. Health served as both a motivator and a barrier to physical activity. Other factors influencing physical activity were weather, transportation, and personal safety. Findings from this study suggest strategies for culture-specific programming of community-based physical activity programs.

  9. Patients' mental models and adherence to outpatient physical therapy home exercise programs.

    Science.gov (United States)

    2015-05-01

    Within physical therapy, patient adherence usually relates to attending appointments, following advice, and/or undertaking prescribed exercise. Similar to findings for general medical adherence, patient adherence to physical therapy home exercise programs (HEP) is estimated between 35 and 72%. Adherence to HEPs is a multifactorial and poorly understood phenomenon, with no consensus regarding a common theoretical framework that best guides empirical or clinical efforts. Mental models, a construct used to explain behavior and decision-making in the social sciences, may serve as this framework. Mental models comprise an individual's tacit thoughts about how the world works. They include assumptions about new experiences and expectations for the future based on implicit comparisons between current and past experiences. Mental models play an important role in decision-making and guiding actions. This professional theoretical article discusses empirical research demonstrating relationships among mental models, prior experience, and adherence decisions in medical and physical therapy contexts. Specific issues related to mental models and physical therapy patient adherence are discussed, including the importance of articulation of patients' mental models, assessment of patients' mental models that relate to exercise program adherence, discrepancy between patient and provider mental models, and revision of patients' mental models in ways that enhance adherence. The article concludes with practical implications for physical therapists and recommendations for further research to better understand the role of mental models in physical therapy patient adherence behavior.

    To describe changes in physical activity (PA) and exercise dependence score during treatment of eating disorders (ED), and to explore correlations among changes in PA, exercise motivation, exercise dependence score and ED psychopathology in excessive and non-excessive exercisers. Thirty-eight adult females receiving inpatient treatment for anorexia nervosa, bulimia nervosa or ED not otherwise specified participated in this prospective study. Assessments included accelerometer assessed PA, Exercise Dependence Scale, Reasons for Exercise Inventory, ED Examination, and ED Inventory. Amount of PA was significantly reduced in non-excessive exercisers during treatment, in excessive exercisers there was a trend towards reduced amount of PA from admission to discharge. In excessive exercisers, reduced ED psychopathology was correlated with reduction in exercise dependence score and perceived importance of exercise to regulate negative affects, but not with importance of exercise for weight/appearance. These associations were not found in non-excessive exercisers. Excessive exercise is an important issue in longstanding ED, and the excessive exercising patients need help to develop alternative strategies to regulate negative affects.

This revision study approached studies published among the years from 1991 to 2005, through systematic searches using electronic database: Medline, Science Direct and bibliographical collection of Universidade Estadual do Sudoeste da Bahia. The weigh loss process depends on several factors as the number of fatty cells, hereditariness, normality of hormonal system and mainly to the energy expense. The analyzed studies demonstrated that the physical exercise is an mechanism efficiente that contributes in the reduction of corporal weight, allied the other health positive habits. However the intensity, duration and even the ideal modality of physical exercise is controversial in the half specialized, having a certain predominance of studies that they appear for exercises drop aerobics the moderate intensity due to minimizes risks the health. The studies addressed for the anaerobic exercises they demonstrated to be more efficient in the control of corporal weight, because besides contributing for loss of corporal fat it favors the maintenance and/our increase of thin corporal mass. Experimental studies are recommended with wider delineamento than it favors to investigate the relationship of different types of physical exercise in the control of corporal weight.

    The excess in physical activity could be closely linked to considerable negative consequences on the whole body. These dysfunctions called as "female athlete triad"' by the American College of Sports Medicine (ACSM) include amenorrhea, osteoporosis and disorder eating. The female athlete triad poses serious health risks, both on the short and on the long term, to the overall well-being of affected individuals. Sustained low energy availability can impair health, causing many medical complications within skeletal, endocrine, cardiovascular, reproductive and central nervous system. On the contrary, several studies have shown, that physical activity improves cardiovascular risk factors, hormonal profile and reproductive function. These improvements include a decrease in abdominal fat, blood glucose, blood lipids and insulin resistance, as well as improvements in menstrual cyclicity, ovulation and fertility, decreases in testosterone levels and Free Androgen Index (FAI) and increases in sex hormone binding globulin (SHBG). Other studies reported that physical activity improved self-esteem, depression and anxiety. Thus, the aim of this review is to elucidate the effect of physical exercise on female reproductive system and viceversa the impact of hormonal status on physical activity and metabolism. In addition this review supports the idea that physical exercise is a helpful tool for the management of obesity, prevention of cardiovascular, metabolic diseases and female reproductive organs related diseases (e.g. breast cancer). When the excess in physical activity leads up to the female athlete triad, it is imperative to treat each component of the triad by employing both pharmacological and non pharmacological treatments.

    The positive effects of regular exercise for cancer survivors are becoming increasingly apparent. However, comprehensive examination of the benefits of modest levels of physical activity is somewhat lacking. This study aimed to test the hypothesis that participating in a 12-session exercise program will improve depression, fatigue, aerobic endurance, muscular strength, and quality of life (QOL) in patients with cancer. A group of 20 older adult women with a prior cancer diagnosis were evaluated during a 6- to 10-week exercise program that occurred twice weekly. The majority of patients had breast cancer (n = 14), but treatment status varied (11 were currently undergoing treatment, and 9 were post-treatment). Each patient completed initial and exit assessments, which consisted of three physical function tests and three psychosocial questionnaires. Patient charts contained the initial and final assessment scores and personal demographics. Analyses of pre- and postprogram data using paired t tests revealed that 12 exercise sessions (each lasting about an hour) significantly improved six-minute walk test, 30-second sit-and-stand test, hand grip strength test (dominant and nondominant hand), and overall QOL scores in patients. As a result, moderate levels of exercise have a beneficial effect in this population.

    Most health care professionals involved in the management of people with haemophilia (PWH) believe that exercise is beneficial and its practice is widely encouraged. This article aims to demonstrate that appropriate exercise (adapted to the special needs of the individual PWH) may be beneficial for all PWH through improved physical, psychosocial and medical status. Based on evidence gathered from the literature, many PWH, particularly those using long-term prophylaxis or exhibiting a mild/moderate bleeding phenotype, are as active as their healthy peers. PWH experience the same benefits of exercise as the general population, being physically healthier than if sedentary and enjoying a higher quality of life (QoL) through social inclusion and higher self-esteem. PWH can also gain physically from increased muscle strength, joint health, balance and flexibility achieved through physiotherapy, physical activity, exercise and sport. Conversely, very little data exist on activity levels of PWH in countries with limited resources. However, regarding specific exercise recommendations in PWH, there is a lack of randomized clinical trials, and consequently formal, evidence-based guidelines have not been produced. Based on published evidence from this review of the literature, together with the clinical experience of the authors, a series of recommendations for the safe participation of PWH in regular physical activities, exercises and sport are now proposed. In summary, we believe that appropriately modified programmes can potentially allow all PWH to experience the physical and psychosocial benefits of being physically active which may ultimately lead to an improved QoL. © 2013 John Wiley & Sons Ltd.

    Pre-eclampsia (PE), a characteristic hypertensive disorder of human pregnancy and a leading cause of maternal and fetal mortality and morbidity worldwide, shares some similarities with atherosclerosis, namely the involvement of oxidative stress and of endothelial dysfunction in their pathophysiologies, the presence of similar typical lesions and of common risk factors. Although it is widely accepted that regular physical exercise protects against cardiovascular events, few studies have addressed the impact of physical activity in reducing PE risk. In this paper, similarities between atherosclerosis and PE, involving pathogenic mechanisms, are described. This paper also reviews the studies performed until now that evaluated the impact of regular physical exercise (prenataly or during pregnancy) in reducing risk of PE. The potential mechanisms underlying physical activity as a prophylactic approach of PE, as observed with cardiovascular diseases, are discussed.

    Lung cancer continues to be a difficult disease frequently diagnosed in late stages with a high mortality and symptom burden. In part because of frequent lung comorbidity, even lung cancer survivors often remain symptomatic and functionally limited. Though targeted therapy continues to increase treatment options for advanced-stage disease, symptom burden remains high with few therapeutic options. In the last several decades, exercise and physical activity have arisen as therapeutic options for obstructive lung disease and lung cancer. To date, exercise has been shown to reduce symptoms, increase exercise tolerance, improve quality of life, and potentially reduce length of stay and postoperative complications. Multiple small trials have been performed in perioperative non-small-cell lung cancer patients, although fewer studies are available for patients with advanced-stage disease. Despite the increased interest in this subject over the last few years, a validated exercise regimen has not been established for perioperative or advanced-stage disease. Clinicians underutilize exercise and pulmonary rehabilitation as a therapy, in part because of the lack of evidence-based consensus as to how and when to implement increasing physical activity. This review summarizes the existing evidence on exercise in lung cancer patients.

  20. Treatment of Dyslipidemia with Statins and Physical Exercises: Recent Findings of Skeletal Muscle Responses

    Full Text Available Statin treatment in association with physical exercise practice can substantially reduce cardiovascular mortality risk of dyslipidemic individuals, but this practice is associated with myopathic event exacerbation. This study aimed to present the most recent results of specific literature about the effects of statins and its association with physical exercise on skeletal musculature. Thus, a literature review was performed using PubMed and SciELO databases, through the combination of the keywords “statin” AND “exercise” AND “muscle”, restricting the selection to original studies published between January 1990 and November 2013. Sixteen studies evaluating the effects of statins in association with acute or chronic exercises on skeletal muscle were analyzed. Study results indicate that athletes using statins can experience deleterious effects on skeletal muscle, as the exacerbation of skeletal muscle injuries are more frequent with intense training or acute eccentric and strenuous exercises. Moderate physical training, in turn, when associated to statins does not increase creatine kinase levels or pain reports, but improves muscle and metabolic functions as a consequence of training. Therefore, it is suggested that dyslipidemic patients undergoing statin treatment should be exposed to moderate aerobic training in combination to resistance exercises three times a week, and the provision of physical training prior to drug administration is desirable, whenever possible.

    Purpose of the review The purpose of this review is to critically assess the evidence for exercise as an adjunct intervention for major depressive disorder and bipolar disorder, chronic conditions characterized by frequent comorbid conditions as well as interepisodic symptoms with poor quality of life and impaired functioning. Individuals with these mood disorders are at higher risk of cardiovascular disease and premature death in part because of increased rates of obesity, inactivity, and diabetes mellitus compared to the general population. Exercise may not only mitigate the increased risk of cardiovascular disease, but could also potentially improve the long term outcomes of mood disorders. Recent findings We conducted a literature review on the impact of exercise on mood disorders and associated comorbid conditions as well as possible biological mechanisms. We found that exercise impacts both the physical health parameters of mood disorders as well as mental health outcomes. Exercise also positively impacts conditions frequently comorbid with mood disorders (i.e. anxiety, pain, and insomnia). There are multiple candidate biomarkers for exercise, with brain-derived neurotrophic factor and oxidative stress as two main promising components of exercise’s anti-depressant effect. Summary Exercise appears to be a promising adjunct treatment for mood disorders. We conclude with recommendations for future research of exercise as an adjunct intervention for mood disorders.

    Full Text Available The present aim was to investigate functionality of vibrotactile stimulation in mimicry-based behavioral regulation during physical exercise. Vibrotactile stimuli communicated instructions from an instructor to an exerciser to perform lower extremity movements. A wireless prototype was tested first in controlled laboratory conditions (Study 1 and was followed by a user study (Study 2 that was conducted in a group exercise situation for elderly participants with a new version of the system with improved construction and extended functionality. The results of Study 1 showed that vibrotactile instructions were successful in both supplementing and substituting visual knee lift instructions. Vibrotactile stimuli were accurately recognized, and exercise with the device received affirmative ratings. Interestingly, tactile stimulation appeared to stabilize acceleration magnitude of the knee lifts in comparison to visual instructions. In Study 2 it was found that user experience of the system was mainly positive by both the exercisers and their instructors. For example, exercise with vibrotactile instructions was experienced as more motivating than conventional exercise session. Together the results indicate that tactile instructions could increase possibilities for people having difficulties in following visual and auditory instructions to take part in mimicry-based group training. Both studies also revealed development areas that were primarily related to a slight delay in triggering the vibrotactile stimulation.

    To examine associations among exercise dependence score, amount of physical activity and eating disorder (ED) symptoms in patients with longstanding ED and non-clinical controls. Adult female inpatients (n = 59) and 53 age-matched controls participated in this cross sectional study. Assessments included the eating disorders examination, eating disorders inventory, exercise dependence scale, reasons for exercise inventory, and MTI Actigraph accelerometer. Positive associations were found among vigorous, not moderate, physical activity, exercise dependence score and ED symptoms in patients. In the controls, ED symptoms were negatively associated with vigorous physical activity and not correlated with exercise dependence score. Exercise for negative affect regulation, not weight/appearance, and amount of vigorous physical activity were explanatory variables for exercise dependence score in both groups. The positive associations among exercise dependence score, vigorous physical activity and ED symptoms need proper attention in the treatment of longstanding ED.

    To compare physical activity level (PAL) and care related to exercise in patients with diabetes mellitus (DM). DM outpatients (adult, insulin-user patients) were assessed for PAL (international questionnaire; moderate- and high-level activities, as well as walking, over a typical week) and questioned about formal exercise practice, self-care, and hypoglycemic episodes related to exercise or reasons for not exercising. Two hundred twenty five patients were assessed: 107 (47.6%) had type 2 diabetes mellitus (DM2) and 118 (52.4%) had type 1 diabetes mellitus (DM1), with a larger percentage of patients with DM2 being classified as poorly active [33 (30.7%) versus 12 (10.3%)] and a lower percentage being classified as highly active [9 (8.7%) versus 29 (25%)], compared with patients having DM1. Patients who do not exercise (n = 140) gave different reasons for not doing so: patients with DM2 claimed that they "felt uncomfortable", "presented medical restrictions", and "did not like it"; DM1 patients claimed that they "had no time to exercise", "were lazy", and "had hypoglycemic episodes". Only 85 patients exercised regularly, regardless of the PAL, and 38.8% performed self-care, such as eating, stretching, and capillary glucose monitoring. Patients with DM2 [5 (14.3%)] reported a lower number of hypoglycemic episodes related to exercise than those with DM1 [17 (34%)]. Patients with DM2 have different PAL and behavior related to exercise than those seen in DM1 patients.

    Physical activity facilitates neurogenesis of dentate cells in the rodent hippocampus, a brain region critical for memory formation and spatial representation. Recent findings in humans also suggest that aerobic exercise can lead to increased hippocampal volume and enhanced cognitive functioning in children and elderly adults. However, the association between physical activity and hippocampal volume during the period from early adulthood through middle age has not been effectively explored. Here, we correlated the number of minutes of self-reported exercise per week with gray matter volume of the hippocampus using voxel-based morphometry (VBM) in 61 healthy adults ranging from 18 to 45 years of age. After controlling for age, gender, and total brain volume, total minutes of weekly exercise correlated significantly with volume of the right hippocampus. Findings highlight the relationship between regular physical exercise and brain structure during early to middle adulthood.

    The hippocampus plays an integral role in certain aspects of cognition. Hippocampal structural plasticity and in particular adult hippocampal neurogenesis can be influenced by several intrinsic and extrinsic factors. Here we review how hormones (i.e., intrinsic modulators) and physical exercise (i.e., an extrinsic modulator) can differentially modulate hippocampal plasticity in general and adult hippocampal neurogenesis in particular. Specifically, we provide an overview of the effects of sex hormones, stress hormones, and metabolic hormones on hippocampal structural plasticity and adult hippocampal neurogenesis. In addition, we also discuss how physical exercise modulates these forms of hippocampal plasticity, giving particular emphasis on how this modulation can be affected by variables such as exercise regime, duration, and intensity. Understanding the neurobiological mechanisms underlying the modulation of hippocampal structural plasticity by intrinsic and extrinsic factors will impact the design of new therapeutic approaches aimed at restoring hippocampal plasticity following brain injury or neurodegeneration.

    Fibromyalgia (FM) affects approximately 1-3 % of the general population. Fatigue limits the work ability and social life of patients with FM. A few studies of physical exercise have included measures of fatigue in FM, indicating that exercise can decrease fatigue levels. There is limited knowledge about the effects of resistance exercise on multiple dimensions of fatigue in FM. The present study is a sub-study of a multicenter randomized controlled trial in women with FM. The purpose of the present sub-study was to examine the effects of a person-centered progressive resistance exercise program on multiple dimensions of fatigue in women with FM, and to investigate predictors of the potential change in fatigue. A total of 130 women with FM (age 22-64 years) were included in this assessor-blinded randomized controlled multicenter trial examining the effects of person-centered progressive resistance exercise compared with an active control group. The intervention was performed twice a week for 15 weeks. Outcomes were five dimensions of fatigue measured with the Multidimensional Fatigue Inventory (MFI-20). Information about background was collected and the women also completed several health-related questionnaires. Multiple linear stepwise regression was used to analyze predictors of change in fatigue in the total population. A higher improvement was found at the post-treatment examination for change in the resistance exercise group, as compared to change in the active control group in the MFI-20 subscale of physical fatigue (resistance group Δ -1.7, SD 4.3, controls Δ 0.0, SD 2.7, p = 0.013), with an effect size of 0.33. Sleep efficiency was the strongest predictor of change in the MFI-20 subscale general fatigue (beta = -0.54, p = 0.031, R (2) = 0.05). Participating in resistance exercise (beta = 1.90, p = 0.010) and working fewer hours per week (beta = 0.84, p = 0.005) were independent significant predictors of change in physical

    Inflammatory markers are increased systematically and locally (e.g., skeletal muscle) in stroke patients. Besides being associated with cardiovascular risk factors, proinflammatory cytokines seem to play a key role in muscle atrophy by regulating the pathways involved in this condition. As such, they may cause severe decrease in muscle strength and power, as well as impairment in cardiorespiratory fitness. On the other hand, physical exercise (PE) has been widely suggested as a powerful tool for treating stroke patients, since PE is able to regenerate, even if partially, physical and cognitive functions. However, the mechanisms underlying the beneficial effects of physical exercise in poststroke patients remain poorly understood. Thus, in this study we analyze the candidate mechanisms associated with muscle atrophy in stroke patients, as well as the modulatory effect of inflammation in this condition. Later, we suggest the two strongest anti-inflammatory candidate mechanisms, myokines and the cholinergic anti-inflammatory pathway, which may be activated by physical exercise and may contribute to a decrease in proinflammatory markers of poststroke patients.

    To provide a physical exercise programme for older adults living in nursing homes. Pain is common among older persons and for those already in long-term care and having difficulty in coping with pain will be at risk of further reducing their optimal independent function. A quasi-experimental single group pretest-posttest design. Older persons from a nursing home were invited to join an eight-week physical exercise programme. Each session lasted an hour and sessions were conducted once a week by physiotherapist and nurses. Physical exercise programme consisted of stretching, strengthening, balancing, towel dancing and self-administered massage to various acupressure points. On completion of each session, older persons were given a pamphlet with pictures to illustrate the exercise of the day and they were encouraged to practise these exercises by themselves. Outcome measures including pain intensity, range of movement, activities of daily living and mobility were collected before and after the physical exercise programme. There were 75 older adult participants (57 female and 18 male, mean age 85.14 SD 5.30). Seventy-three percent (n = 55) of them had pain in the previous three months and were referred as pain group, while 25% (n = 20) were no pain group. Pain scores of 4.89 (on a 10-point scale) indicated medium pain intensity before the intervention for the pain group; the location of pain was mainly in the knee, back and shoulder. On completion of the physical exercise programme, there was a significant decrease in pain intensity to 2.89 (SD 2.14) (p daily living remained unchanged. The present study demonstrated the effectiveness of a physical exercise programme in relieving pain and enhancing functional mobility for older persons. Relevance to clinical practice.  It is important to educate older persons, especially those living in nursing homes, on the importance of engaging in regular physical exercise and maintaining mobility. © 2011 Blackwell Publishing Ltd.

    There is a paucity of research investigating the effects of innovative physical activity programs on physical health and academic performance in the Latino population. To examine the impact of Dance Dance Revolution [DDR]-based exercise on Latino children's physical fitness and academic achievement. A repeated-measures crossover design was used. In Year 1, Grade-4 students were assigned to the intervention group and offered 30 minutes of exercise (DDR, aerobic dance) three times per week. Grade-3 and Grade-5 students made up the comparison group and were offered no structured exercise at school. In Year 2, the Grade-4 students were again assigned to the intervention, whereas Grade-5 and Grade-6 students were in the comparison group. Assessments were conducted with 208 Latino school children. The baseline measures included time to complete a 1-mile run, BMI, and reading and math scores. Data were collected again 9 months later. Overall, data were collected in 2009-2011 and analyzed in 2012. Data yielded significant differences between the intervention and comparison groups in differences in 1-mile run and math scores in Year 1 and Year 2. The results also revealed net differences in the intervention versus comparison group scores on the 1-mile run for Grade 3 (p<0.01). Additionally, children's yearly pre-test and post-test BMI group changes differed (χ(2)((2)) = 6.6, p<0.05) only for the first year of intervention. The DDR-based exercise intervention improved children's cardiorespiratory endurance and math scores over time. Professionals should consider integrating exergaming at schools to achieve the goals of promoting a physically active lifestyle and enhancing academic success among Latino children.

    The present study examined effects of sex, attitude towards physical activity, perceived barriers for participation in physical activity, and students' perception of their parents' participation in physical activity on the intrinsic motivation of students participating in a health related program in physical education. 643 students (303 boys and 340 girls) responded to questionnaires measuring intrinsic motivation, attitudes towards physical activity, perceived barriers to exercise and perceived parents' participation in physical activity. Mean age was 12.9 yr. (SD=1.2, range 11-14 years). Analysis indicated that students' intrinsic motivation towards the program was influenced by perceived barriers to exercise. Sex, attitudes towards physical activity, and perceived parents' participation in physical activity seem to be less important.

Age, sex, physical exercise realization, type and duration of exercise, diagnosis of anxiety and/or depression, exercise prescription, prescriber health personnel and use of psychotropic medication. 294 participants (78.19% of selected) with a mean age of 55.33 years (55.32±12.53 SD) and 78.2% were female. 60.9% were diagnosed with anxiety, 59.5% with depression and 20.4% both diagnoses. 62.9% used antidepressants, benzodiazepines 76.9% and 39.79% both treatments. 58.5% (95%CI: 52.70-64.31) performed exercise of which 44.77% did it 3-5 times/week. The mean duration was 1.24h each time (95%CI: 0.53-1.96). The physical exercise was prescribed to the 59.18% (95%CI: 53.39-64.97); 90.23% by the family physician, 63.22% primary care nurse, 17.24% psychiatrist and 5.17% psychologist. The adherence to the prescription was 59.77% (95%CI: 52.20-67.34). The percentage of anxious and/or depressed patients who practiced exercise is similar to the general population but should be higher. The exercise prescription by health personnel is insufficient.

    Frailty is a state of vulnerability associated with increased risks of fall, hospitalization, cognitive deficits, and psychological distress. Studies with healthy senior suggest that physical exercise can help improve cognition and quality of life. Whether frail older adults can show such benefits remains to be documented. A total of 83 participants aged 61-89 years were assigned to an exercise-training group (3 times a week for 12 weeks) or a control group (waiting list). Frailty was determined by a complete geriatric examination using specific criteria. Pre- and post-test measures assessed physical capacity, cognitive performance, and quality of life. Compared with controls, the intervention group showed significant improvement in physical capacity (functional capacities and physical endurance), cognitive performance (executive functions, processing speed, and working memory), and quality of life (global quality of life, leisure activities, physical capacity, social/family relationships, and physical health). Benefits were overall equivalent between frail and nonfrail participants. Physical exercise training leads to improved cognitive functioning and psychological well-being in frail older adults.

    This systematic review was conducted to provide rich and deep evidence of the perceived determinants and consequences of physical activity and exercise based on qualitative research in multiple sclerosis (MS). Electronic databases and article reference lists were searched to identify qualitative studies of physical activity and exercise in MS. Studies were included if they were written in English and examined consequences/determinants of physical activity in persons with MS. Content analysis of perceived determinants and consequences of physical activity and exercise was undertaken using an inductive analysis guided by the Physical Activity for people with Disabilities framework and Social Cognitive Theory, respectively. Nineteen articles were reviewed. The most commonly identified perceived barriers of physical activity and exercise were related to the environmental (i.e. minimal or no disabled facilities, and minimal or conflicting advice from healthcare professionals) and related to personal barriers (i.e. fatigue, and fear and apprehension). The most commonly identified perceived facilitators of physical activity were related to the environment (i.e. the type of exercise modality and peer support) and related to personal facilitators (i.e. appropriate exercise and feelings of accomplishment). The most commonly identified perceived beneficial consequences of physical activity and exercise were maintaining physical functions, increased social participation and feelings of self-management and control. The most commonly identified perceived adverse consequences were increased fatigue and feelings of frustration and lost control. Results will inform future research on the perceived determinants and consequences of physical activity and exercise in those with MS and can be adopted for developing professional education and interventions for physical activity and exercise in MS. Physical activity and exercise behaviour in people with multiple sclerosis (MS) is subject

  20. Frailty, Disability and Physical Exercise in the Aging Process and in Chronic Kidney Disease

    Full Text Available Frailty in the elderly is a state of vulnerability to poor resolution of homoeostasis after a stressor event and is a consequence of cumulative decline in many physiological systems during a lifetime. This cumulative decline depletes homoeostatic reserves until minor stressor events trigger disproportionate changes in health status. It is usually associated to adverse health outcomes and to one-year mortality risk. Physical exercise has found to be effective in preventing frailty and disability in this population. Chronic kidney disease (CKD is also a clinical condition where protein energy-wasting, sarcopenia and dynapenia ,very common symptoms in the frail elderly, may occur. Moreover elderly and CKD patients are both affected by an impaired physical performance that may be reversed by physical exercise with an improvement of the survival rate. These similarities suggest that frailty may be a common pathway of aging and CKD that may induce disability and that can be prevented by a multidimensional approach in which physical exercise plays an important role.

    The purpose of the current study was to examine whether the effects of social support on physical exercise in older adults depend on individual perceptions of self-efficacy. Three hundred nine older German adults (age 65-85) were assessed at 3 points in time (3 months apart). In hierarchical-regression analyses, support received from friends and exercise self-efficacy were specified as predictors of exercise frequency while baseline exercise, sex, age, and physical functioning were controlled for. Besides main effects of self-efficacy and social support, an interaction between social support and self-efficacy emerged. People with low self-efficacy were less likely to be active in spite of having social support. People with low support were less likely to be active even if they were high in self-efficacy. This points to the importance of both social support and self-efficacy and implies that these resources could be targets of interventions to increase older adults' exercise.

    Trypanosoma cruzi causes neuronal myenteric depopulation compromising intestinal function. The purpose of this study was to evaluate the influence of moderate physical exercise on NADH diaphorase (NADH-d)-positive neurons in the myenteric plexus and intestinal wall of the colon in mice infected with T. cruzi. Forty 30-day-old male Swiss mice were divided into the following groups: trained infected (TI), sedentary infected (SI), trained control (TC), and sedentary control. The TC and TI groups were subjected to a moderate physical exercise program on a treadmill for 8 weeks. Three days after finishing physical exercise, the TI and SI groups were intraperitoneally inoculated with 1,300 blood trypomastigotes of the Y strain of Trypanosoma cruzi. Parasitemia was evaluated from days 4 to 61 after inoculation. On day 75 of infection, myenteric neurons in the colon were quantified (NADH-d), and inflammatory foci were counted. Tumor necrosis factor-α (TNF-α) and transforming growth factor-β (TGF-β) levels were evaluated in plasma. The results were compared using analysis of variance and the Kruskal-Wallis test at a 5 % significance level. Moderate physical exercise reduced the parasite peak on day 8 of infection (p = 0.0132) and total parasitemia (p = 0.0307). It also prevented neuronal depopulation (p  0.05). These results reinforce the therapeutic benefits of moderate physical exercise for T. cruzi infection.

    Reinforcing value (motivating value) is a stronger predictor than hedonic value (liking) for engaging in drug use, gambling, and eating. The associations of reinforcing value and liking with physical activity of adults have not yet been studied and may depend on the modes of exercise (e.g., aerobic/cardiovascular exercise, resistance training) under consideration. The purpose of this study was to test associations of the reinforcing value and liking of aerobic exercise training (AT) and resistance exercise training (RT) modes of exercise with usual participation in aerobic and resistance exercise in adults. Men (n=38) and women (n=50) were measured for their liking and relative reinforcing value (RRV) of AT and RT, for their usual vigorous physical activity (VPA) participation, and for usual resistance exercise behavior (Yale physical activity questionnaire). The RRV of AT (RRVAT) and liking of AT were correlated, (r=0.22, pvalue for, but not the liking of, a mode of exercise predicted how much an individual engaged in that mode of exercise. RRVAT (p˂0.01) was positively associated with usual VPA. RRVRT (p˂0.01) was positively associated with RT behavior. The hedonic value of AT and of RT were not associated (p>0.30) with VPA or RT behavior. Reinforcing value of a mode of exercise is a stronger predictor than the liking of that mode of exercise for usual amount of participation in the exercise. Published by Elsevier Inc.

    The skeletal muscle has high sensitivity for the mechanical stress. Because it is enlarged by training, whereas it is easily withered by lack of exercise. When we exercise, skeletal muscle cells per se sense mechanical loading, and muscular remodeling and the muscular hypertrophy occur. It has been revealed that the intracellular signaling through PGC-1α participates in the remodeling of the skeletal muscle, while PGC-1α4, an isoform of PGC-1α, and the dystrophin-glycoprotein complex play important roles in muscular hypertrophy. This review describes the impact of physical exercise gives on the remodeling and hypertrophy of muscle through the signaling.

    Evidence of the effect of leisure time physical activity (LTPA) modes on the motor abilities of a mature population is scarce. The purpose of this study was to compare the motor abilities of physically active and inactive men and women and to examine the associations of different exercise modes and former and recent LTPA (R-LTPA) with motor ability and various physical tests. The LTPA of the participants (men n = 69, women n = 79; aged 41-47 yr) was ascertained by a modified Physical Activity Readiness Questionnaire, including questions on the frequency, duration, and intensity of R-LTPA and former LTPA and on exercise modes. Motor abilities in terms of balance, agility, and coordination were assessed with a battery of nine tests supplemented with five physical fitness tests. Multiple statistical methods were used in analyses that were conducted separately for men and women. The MET-hours per week of R-LTPA correlated statistically significantly with the tests of agility and static balance (rs = -0.28, P = 0.022; rs = -0.25, P = 0.043, respectively) among men and with the static balance (rs = 0.41), 2-km walking (rs = 0.36), step squat (rs = 0.36) (P women. In the stepwise regression among men, the most frequent statistically significant predictor was the playing of several games. For women, a history of LTPA for more than 3 yr was the strongest predictor for good results in almost all tests. Participants with long-term and regular LTPA had better motor performance, and especially a variety of games improve components of motor ability. Diverse, regular, and long-term exercise including both specific training and general activity develops both motor abilities and physical fitness.

    Andrade, Flávio Maciel Dias de; Pedrosa, Rodrigo Pinto

    2016-01-01

    Obstructive sleep apnea (OSA) is a common clinical condition, with a variable and underestimated prevalence. OSA is the main condition associated with secondary systemic arterial hypertension, as well as with atrial fibrillation, stroke, and coronary artery disease, greatly increasing cardiovascular morbidity and mortality. Treatment with continuous positive airway pressure is not tolerated by all OSA patients and is often not suitable in cases of mild OSA. Hence, alternative methods to treat OSA and its cardiovascular consequences are needed. In OSA patients, regular physical exercise has beneficial effects other than weight loss, although the mechanisms of those effects remain unclear. In this population, physiological adaptations due to physical exercise include increases in upper airway dilator muscle tone and in slow-wave sleep time; and decreases in fluid accumulation in the neck, systemic inflammatory response, and body weight. The major benefits of exercise programs for OSA patients include reducing the severity of the condition and daytime sleepiness, as well as increasing sleep efficiency and maximum oxygen consumption. There are few studies that evaluated the role of physical exercise alone for OSA treatment, and their protocols are quite diverse. However, aerobic exercise, alone or combined with resistance training, is a common point among the studies. In this review, the major studies and mechanisms involved in OSA treatment by means of physical exercise are presented. In addition to systemic clinical benefits provided by physical exercise, OSA patients involved in a regular, predominantly aerobic, exercise program have shown a reduction in disease severity and in daytime sleepiness, as well as an increase in sleep efficiency and in peak oxygen consumption, regardless of weight loss. RESUMO A apneia obstrutiva do sono (AOS) é uma condição clínica comum, possuindo prevalência variável e subestimada. Principal condição associada à hipertens

    2004-12-01

    The purpose of this study was to investigate how scores on the Physical Self-Perception Profile (PSPP), including scores on the Perceived Importance Profile (PIP), were related to self-reported exercise frequency, duration, and gender in sample of Swedish university students. A total of 164 participants completed the PSPP, PIP, and a questionnaire focusing on frequency and duration of exercise. Exercise frequency, duration, and gender predicted best the PSPP sub-domains of Sport Competence and Physical Conditioning. Exercising more frequently, and for a longer time on each occasion was associated with higher PSPP and PIP scores. Women generally displayed lower PSPP scores than men. These results suggest that exercise professionals need to master a range of appropriate exercise strategies, since doubts concerning self-presentation may work against establishing a regular exercise routine.

    Cross-sectional. An epidemiological study describing leisure time physical activities (LTPA) and the associations of barriers, sociodemographic and injury characteristics to moderate-vigorous aerobic exercise participation among individuals with spinal cord injury (SCI) in a developing Southeast Asian country. SCI community in Malaysia. The study sample consisted of 70 participants with SCI. Questionnaires were distributed containing an abbreviated Physical Activity Scale for Individuals with Physical Disabilities (items 2-6) and the Barriers to Exercise Scale using a 5-tier Likert format. Statistical analyses were χ 2 tests, odds ratios, and binary forward stepwise logistic regression to assess the association and to predict factors related to participation in moderate-vigorous intensity aerobic exercise (items 4 and 5). Seventy-three percent of the study sample did not participate in any form of moderate or vigorous LTPA. The top three barriers to undertaking LTPA (strongly agree and agree descriptors) were expensive exercise equipment (54%), pain (37%) and inaccessible facilities (36%). Participants over the age of 35 years, ethnicity, health concerns, perceiving exercise as difficult and indicating lack of transport were significantly different (p exercise type of LTPA. Age, ethnicity, indicated health concerns and lack of transport were the significant predictors in likelihood of participating in moderate-vigorous LTPA (p exercising is too difficult, pain while exercising, age more than 35), interpersonal (different ethnicity), community (expensive exercise equipment), and policy levels (lack of or poor access to transportation, inaccessible facilities) that prevent LTPA participation.

    Does physical exercise training improve physical function and quality of life in people with cognitive impairment and dementia? Which training protocols improve physical function and quality of life? How do cognitive impairment and other patient characteristics influence the outcomes of exercise training? Systematic review with meta-analysis of randomised trials. People with mild cognitive impairment or dementia as the primary diagnosis. Physical exercise. Strength, flexibility, gait, balance, mobility, walking endurance, dual-task ability, activities of daily living, quality of life, and falls. Forty-three clinical trials (n=3988) were included. According to the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) system, the meta-analyses revealed strong evidence in support of using supervised exercise training to improve the results of 30-second sit-to-stand test (MD 2.1 repetitions, 95% CI 0.3 to 3.9), step length (MD 5cm, 95% CI 2 to 8), Berg Balance Scale (MD 3.6 points, 95% CI 0.3 to 7.0), functional reach (3.9cm, 95% CI 2.2 to 5.5), Timed Up and Go test (-1second, 95% CI -2 to 0), walking speed (0.13m/s, 95% CI 0.03 to 0.24), and 6-minute walk test (50m, 95% CI 18 to 81) in individuals with mild cognitive impairment or dementia. Weak evidence supported the use of exercise in improving flexibility and Barthel Index performance. Weak evidence suggested that non-specific exercise did not improve dual-tasking ability or activity level. Strong evidence indicated that exercise did not improve quality of life in this population. The effect of exercise on falls remained inconclusive. Poorer physical function was a determinant of better response to exercise training, but cognitive performance did not have an impact. People with various levels of cognitive impairment can benefit from supervised multi-modal exercise for about 60minutes a day, 2 to 3days a week to improve physical function.

    Grounded in self-determination theory (Deci & Ryan, 1985), the purpose of the present study was to examine whether amotivation, self-determined and controlling types of motivation could predict a range of exercise-related behaviours, cognitions and physical self-evaluations. Exercisers (n = 375) from ten health clubs in the North of England completed questionnaires measuring exercise motivation, exercise stages of change, number of relapses from exercise, future intention to exercise, barriers self-efficacy, physical self-worth and social physique anxiety. Controlling for age and sex, multiple and logistic regression analyses supported our hypotheses by showing self-determined motivation (i.e. intrinsic motivation and identified regulation) to predict more adaptive behavioural, cognitive and physical self-evaluation patterns than external regulation and amotivation. Introjected regulation was related to both adaptive and maladaptive outcomes. Furthermore, a multivariate analysis of variance revealed that exercisers in the maintenance stage of change displayed significantly more self-determined motivation to exercise than those in the preparation and action stages. The results illustrate the importance of promoting self-determined motivation in exercisers to improve the quality of their experiences, as well as to foster their exercise behaviour. Future research should examine the mechanisms that promote self-determined motivation in exercise.

    The aim of this research was to describe Punjabi Sikh patients' perceived barriers to engaging in physical exercise following myocardial infarction (MI). A qualitative, interpretive descriptive methodology was used. The sample included 15 Punjabi Sikh patients who were attending a cardiac rehabilitation education program in an urban center of British Columbia, Canada, following MI. Data were collected via semi-structured interviews and were audio recorded, translated from Punjabi to English, and transcribed verbatim. Data were analyzed using an interpretive thematic approach that involved a process of coding and constant comparison. Four key factors emerged that related to participants' perceived barriers to sustained engagement in physical activity: (1) difficulty in determining safe exertion levels independently; (2) fatigue and weakness; (3) preference for 'informal' exercise; and (4) migration-related challenges. The findings have implications for the design and delivery of health promotion strategies aimed at Punjabi Sikh patients' post-MI that is contingent on the use of 'formal' exercise settings to promote regular physical activity. The willingness among Punjabi Sikh patients to practise brisk walking offers a positive direction that public health nurses and other healthcare professionals may want to capitalize on in the delivery of exercise-related health promotion. © 2012 Wiley Periodicals, Inc.

    Despite numerous health benefits, less than half of American adults engage in regular physical activity. Exercise videogames (EVG) may be a practical and attractive alternative to traditional forms of exercise. However there is insufficient research to determine whether EVG play alone is sufficient to produce prolonged engagement in physical activity or improvements in cardiovascular fitness and overall health risk. The goal of the present study is to test the efficacy of exercise videogames to increase time spent in moderate to vigorous physical activity (MVPA) and to improve cardiovascular risk indices among adults. Wii Heart Fitness is a rigorous 3-arm randomized controlled trial with adults comparing three 12-week programs: (1) supervised EVGs, (2) supervised standard exercise, and (3) a control condition. Heart rate is monitored continuously throughout all exercise sessions. Assessments are conducted at baseline, end of intervention (week 12), 6 and 9 months. The primary outcome is time spent in MVPA physical activity. Secondary outcomes include changes in cardiovascular fitness, body composition, blood lipid profiles and maintenance of physical activity through six months post-treatment. Changes in cognitive and affective constructs derived from Self Determination and Social Cognitive Theories will be examined to explain the differential outcomes between the two active treatment conditions. The Wii Heart Fitness study is designed to test whether regular participation in EVGs can be an adequate source of physical activity for adults. This study will produce new data on the effect of EVGs on cardiovascular fitness indices and prolonged engagement with physical activity. Copyright © 2015 Elsevier Inc. All rights reserved.

    This investigation described the effects of exercise, walking, and cycling for transportation, as well as the effect of overall nonexercise physical activity, on mortality in the Shanghai Women's Health Study (1997-2004). Women without heart disease, stroke, or cancer were followed for an average of 5.7 years (n = 67,143), and there were 1,091 deaths from all causes, 537 deaths from cancer, and 251 deaths from cardiovascular diseases. Information about physical activity and relevant covariates was obtained by interview. Proportional hazards models were used to estimate adjusted hazard ratios and 95% confidence intervals. Exercise and cycling for transportation were both inversely and independently associated with all-cause mortality (p(trend) activity were at 25-50% reduced risk (p(trend) active women (0-9.9 MET-hours/day). Among women reporting the least nonexercise activity (0-9.9 MET-hours/day) but reporting regular exercise participation, exercise was associated with reduced mortality (hazard ratio = 0.78, 95% confidence interval: 0.62, 0.99). These findings add new evidence that overall physical activity levels are an important determinant of longevity, and that health benefit can be obtained through an active lifestyle, exercise, or combinations of both.

    This study examined the combined effect of physical exercise and cognitive training on memory and neurotrophic factors in healthy, young adults. Ninety-five participants completed 6 weeks of exercise training, combined exercise and cognitive training, or no training (control). Both the exercise and combined training groups improved performance on a high-interference memory task, whereas the control group did not. In contrast, neither training group improved on general recognition performance, suggesting that exercise training selectively increases high-interference memory that may be linked to hippocampal function. Individuals who experienced greater fitness improvements from the exercise training (i.e., high responders to exercise) also had greater increases in the serum neurotrophic factors brain-derived neurotrophic factor and insulin-like growth factor-1. These high responders to exercise also had better high-interference memory performance as a result of the combined exercise and cognitive training compared with exercise alone, suggesting that potential synergistic effects might depend on the availability of neurotrophic factors. These findings are especially important, as memory benefits accrued from a relatively short intervention in high-functioning young adults.

    This study examines the effectiveness of physical exercise, during a prepathology state, on locomotor balance compensation after subsequent unilateral labyrinthectomy in squirrel monkeys. An experimental group underwent 3 hr. of daily running exercise on a treadmill for 3 mo. prior to the surgery, whereas a control group was not exercised. Postoperatively, the locomotor balance function of both groups was tested for 3 mo. There was no significant difference in gait deviation counts in the acute phase of compensation. However, in the chronic compensation maintenance phase, the number of gait deviation counts was fewer in the exercise group, which showed significantly better performance stability.

    Previously we showed the involvement of the hippocampal noradrenergic system in the consolidation and persistence of object recognition (OR) memory. Here we show that one-single physical exercise session performed immediately after learning promotes OR memory persistence and increases norepinephrine levels in the hippocampus. Additionally, effects of exercise on memory are avoided by an intra-hippocampal beta-adrenergic antagonist infusion. Taken together, these results suggest that exercise effects on memory can be related to noradrenergic mechanisms and acute physical exercise can be a non-pharmacological intervention to assist memory consolidation and persistence, with few or no side effects.

    Physical exercise is one of the most efficient interventions to mitigate chronic pain symptoms in fibromyalgia (FM). However, little is known about the neurophysiological mechanisms mediating these effects. In this study we investigated resting-state connectivity using functional magnetic resonance imaging (fMRI) before and after a 15 week standardized exercise program supervised by physical therapists. Our aim was to gain an understanding of how physical exercise influences previously shown aberrant patterns of intrinsic brain activity in FM. Fourteen FM patients and eleven healthy controls successfully completed the physical exercise treatment. We investigated post- versus pre-treatment changes of brain connectivity, as well as changes in clinical symptoms in the patient group. FM patients reported improvements in symptom severity. Although several brain regions showed a treatment-related change in connectivity, only the connectivity between the right anterior insula and the left primary sensorimotor area was significantly more affected by the physical exercise among the fibromyalgia patients compared to healthy controls. Our results suggest that previously observed aberrant intrinsic brain connectivity patterns in FM are partly normalized by the physical exercise therapy. However, none of the observed normalizations in intrinsic brain connectivity were significantly correlated with symptom changes. Further studies conducted in larger cohorts are warranted to investigate the precise relationship between improvements in fibromyalgia symptoms and changes in intrinsic brain activity.

    To analyze the factors associated with regular physical exercise and routine consumption of fruits and vegetables, and both healthy behaviors among Mexican older adults. We conducted a secondary data analysis of the baseline data (2014) of the Study on Obesity, Sarcopenia and Fragility in older adults affiliated with the Mexican Institute of Social Security. The study included 948 adults who were ≥60 years of age. Multiple Poisson regression was performed. Routine consumption of fruits and vegetables was reported by 53.8 % of older adults, 42.7 % reported engaging in regular physical exercise and 23.1 % reported participating in both types of healthy behaviors. Women, adults with a stable income, those with a self-perception of good health and those with a history of physical exercise at the age of 50 years had an increased likelihood of engaging in healthy eating and regular physical activity. Many older adults do not routinely consume fruits and vegetables or engage in regular physical exercise despite the fact that most have a fixed income and a social network. It is relevant to conduct research-based interventions that take into account the contextual factors to promote healthy behaviors.

    Normal pregnancy is associated with marked changes in haemodynamic function, however the influence and potential benefits of antenatal physical exercise at different stages of pregnancy and postpartum remain unclear. The aim of this study was therefore to characterise the influence of regular physical exercise on haemodynamic variables at different stages of pregnancy and also in the postpartum period. Fifty healthy pregnant women were recruited and randomly assigned (2 × 2 × 2 design) to a land or water-based exercise group or a control group. Exercising groups attended weekly classes from the 20th week of pregnancy onwards. Haemodynamic assessments (heart rate, cardiac output, stroke volume, total peripheral resistance, systolic and diastolic blood pressure and end diastolic index) were performed using the Task Force haemodynamic monitor at 12-16, 26-28, 34-36 and 12 weeks following birth, during a protocol including postural manoeurvres (supine and standing) and light exercise. In response to an acute bout of exercise in the postpartum period, stroke volume and end diastolic index were greater in the exercise group than the non-exercising control group (p = 0.041 and p = 0.028 respectively). Total peripheral resistance and diastolic blood pressure were also lower (p = 0.015 and p = 0.007, respectively) in the exercise group. Diastolic blood pressure was lower in the exercise group during the second trimester (p = 0.030). Antenatal exercise does not appear to substantially alter maternal physiology with advancing gestation, speculating that the already vast changes in maternal physiology mask the influences of antenatal exercise, however it does appear to result in an improvement in a woman's haemodynamic function (enhanced ventricular ejection performance and reduced blood pressure) following the end of pregnancy.

    Objective The study examined whether couples coping with prostate cancer participating in a partnered exercise program - Exercising Together (ET) - experienced higher levels of physical intimacy (i.e., affectionate & sexual behavior) than couples in a usual care (UC) control group. Method Men and their wives (n=64 couples) were randomly assigned to either the ET or UC group. Couples in the ET group engaged in partnered strength-training twice weekly for six months. Multilevel modeling was used to explore the effects of ET on husband and wife engagement in both affectionate and sexual behaviors over time. Results Controlling for relationship quality, wives in ET showed significant increases in engagement in affectionate behaviors compared to wives in UC. No intervention effects were found for husbands. Conclusion Couple-based approaches to physical intimacy, after a cancer diagnosis, that facilitate collaborative engagement in non-sexual physical activities for the couple have potential to be effective for wives. More research is needed in this area to determine couples most amenable to such exercise strategies, optimal timing in the cancer trajectory, and the benefits of combining partnered exercise with more traditional relationship-focused strategies.

    Sedentary time is increasing in all societies and results in limited non-exercise physical activity (NEPA) of daily life. The importance of low NEPA for cardiovascular health and longevity is limited, especially in elderly. To examine the association between NEPA and cardiovascular health at baseline as well as the risk of a first cardiovascular disease (CVD) event and total mortality after 12.5 years. Cohort study. Every third 60-year-old man and woman in Stockholm County was invited to a health screening study; 4232 individuals participated (78% response rate). At baseline, NEPA and exercise habits were assessed from a self-administrated questionnaire and cardiovascular health was established through physical examinations and laboratory tests. The participants were followed for an average of 12.5 years for the assessment of CVD events and mortality. At baseline, high NEPA was, regardless of regular exercise and compared with low NEPA, associated with more preferable waist circumference, high-density lipoprotein cholesterol and triglycerides in both sexes and with lower insulin, glucose and fibrinogen levels in men. Moreover, the occurrence of the metabolic syndrome was significantly lower in those with higher NEPA levels in non-exercising and regularly exercising individuals. Furthermore, reporting a high NEPA level, compared with low, was associated with a lower risk of a first CVD event (HR=0.73; 95% CI 0.57 to 0.94) and lower all-cause mortality (0.70; 0.53 to 0.98). A generally active daily life was, regardless of exercising regularly or not, associated with cardiovascular health and longevity in older adults.

However, the effect of such an exercise program on physical fitness in frail, obese older adults is not known. We therefore determined the effect of a 3 month-...

    Full Text Available Abstract Background Physical inactivity has become a major public health problem and clear educational differences in physical activity have been reported across Europe and USA. The origins of adulthood physical activity are suggested to be in childhood and adolescence physical activity. Hardly any studies have, however, examined if the educational differences in physical activity might also be due to educational differences in early experiences in physical activity. Thus, our aim was to examine how competitive sports in youth, and exercise in late adolescence, and opinions on physical education (PE in childhood determined adulthood leisure-time physical activity (LTPA in different educational groups. Methods We used cross-sectional population-based National FINRISK 2002 data for 1918 men and 2490 women aged 25 to 64 years. Competitive sports in youth, exercise in late adolescence, and opinions on PE in childhood were assessed retrospectively via self-reports. Adulthood LTPA was collected with 12-month recall. In 2008, we calculated structural equation models including latent variables among the low- ( Results Men more often than women reported that their experience of PE was interesting and pleasant as well as having learned useful skills during PE classes. Men, compared to women, had also been more active in the three selected competitive sports in youth and exercised in late adolescence. Participation in competitive sports in youth among the low-educated and exercise in late adolescence among the high-educated had a direct effect on adulthood LTPA. Among the low-educated, opinions on PE in childhood had an indirect effect on adulthood LTPA through participation in competitive sports in youth whereas among the high-educated, the indirect effect went through exercise in late adolescence. The effects were mainly similar between genders. Conclusions Our study answers to a strong need to assess the determinants of leisure-time physical activity to

    In animals, physical activity has been shown to induce functional and structural changes especially in the hippocampus and to improve memory, probably by upregulating the release of neurotrophic factors. In humans, results on the effect of acute exercise on memory are inconsistent so far. Therefore, the aim of the present study was to assess the effects of a single bout of physical exercise on memory consolidation and the underlying neuroendocrinological mechanisms in young adults. Participants encoded a list of German-Polish vocabulary before exercising for 30 minutes with either high intensity or low intensity or before a relaxing phase. Retention of the vocabulary was assessed 20 minutes after the intervention as well as 24 hours later. Serum BDNF and salivary cortisol were measured at baseline, after learning, and after the intervention. The high-intensity exercise group showed an increase in BDNF and cortisol after exercising compared to baseline. Exercise after learning did not enhance the absolute number of recalled words. Participants of the high-intensity exercise group, however, forgot less vocabulary than the relaxing group 24 hours after learning. There was no robust relationship between memory scores and the increase in BDNF and cortisol, respectively, suggesting that further parameters have to be taken into account to explain the effects of exercise on memory in humans.

    The present study evaluated the effects of exercise training on pyruvate carboxylase protein (PCB) levels in hepatic tissue and glucose homeostasis control in obese mice. Swiss mice were distributed into three groups: control mice (CTL), fed a standard rodent chow; diet-induced obesity (DIO), fed an obesity-inducing diet; and a third group, which also received an obesity-inducing diet, but was subjected to an exercise training protocol (DIO + EXE). Protocol training was carried out for 1 h/d, 5 d/wk, for 8 weeks, performed at an intensity of 60% of exhaustion velocity. An insulin tolerance test (ITT) was performed in the last experimental week. Twenty-four hours after the last physical exercise session, the animals were euthanized and the liver was harvested for molecular analysis. Firstly, DIO mice showed increased epididymal fat and serum glucose and these results were accompanied by increased PCB and decreased p-Akt in hepatic tissue. On the other hand, physical exercise was able to increase the performance of the mice and attenuate PCB levels and hyperglycemia in DIO + EXE mice. The above findings show that physical exercise seems to be able to regulate hyperglycemia in obese mice, suggesting the participation of PCB, which was enhanced in the obese condition and attenuated after a treadmill running protocol. This is the first study to be aimed at the role of exercise training in hepatic PCB levels, which may be a novel mechanism that can collaborate to reduce the development of hyperglycemia and type 2 diabetes in DIO mice.

    The small intestine plays a role in obesity as well as in satiation. However, the effect of physical exercise on the morphology and function of the small intestine during obesity has not been reported to date. This study aimed to evaluate the effects of physical exercise on morphological aspects of the rat small intestine during hypothalamic monosodium glutamate (MSG)-induced obesity. The rats were divided into four groups: Sedentary (S), Monosodium Glutamate (MSG), Exercised (E), and Exercised Monosodium Glutamate (EMSG). The MSG and EMSG groups received a daily injection of monosodium glutamate (4 g/kg) during the 5 first days after birth. The S and E groups were considered as control groups and received injections of saline. At weaning, at 21 days after birth, the EMSG and E groups were submitted to swimming practice 3 times a week until the 90th day, when all groups were sacrificed and the parameters studied recorded. Exercise significantly reduced fat deposits and the Lee Index in MSG-treated animals, and also reduced the thickness of the intestinal wall, the number of goblet cells and intestinal alkaline phosphatase activity. However, physical activity alone increased the thickness and height of villi, and the depth of the crypts. In conclusion, regular physical exercise may alter the morphology or/and functions of the small intestine, reducing the prejudicial effects of hypothalamic obesity.

    Older adults with cognitive complaints are vulnerable to dementia, physical impairments, and poor quality of life. Exercise and mental activity may improve physical function and health-related quality of life (HRQOL) but combinations have not been investigated systematically. The Mental Activity and eXercise (MAX) trial found that mental activity plus exercise over 12weeks improved cognitive function (primary outcome) in sedentary older adults with cognitive complaints. To investigate the effects of combinations of two mental activity and exercise programs on physical function and HRQOL (secondary outcomes). Participants (n=126, age 73±6years, 65% women) were randomized to 12weeks of exercise (aerobic exercise or stretching/toning, 3×60min/week) plus mental activity (computer-based cognitive training or educational DVDs, 3×60min/week) using a factorial design. Assessments included the Senior Fitness Test (physical function), Short Form-12 physical and mental sub-scales (HRQOL), and CHAMPS questionnaire (physical activity). There were no differences between groups at baseline (p>0.05). We observed improvements over time in most physical function measures [chair stands (p-for-time=0.001), arm curls (p-for-timephysical HRQOL (p-for-time=0.04). There were no differences in change between groups (group∗time p>0.05). Changes in most physical function measures and physical HRQOL correlated with physical activity changes. Combined mental activity and exercise interventions of various types can improve both physical function and physical HRQOL among sedentary older adults with cognitive complaints. Exercise control group design should be carefully considered as even light exercise may induce benefits in vulnerable older adults. Copyright © 2017 Elsevier Inc. All rights reserved.

    In patients with moderate to severe chronic obstructive pulmonary disease (COPD) the six-minute walk distance reflects the functional exercise level for daily physical activity. It is unknown if this also applies to patients with mild to moderate COPD in primary care. To assess the relationship between functional exercise capacity and physical activity in patients with mild to moderate COPD. A cross-sectional study was performed in 51 patients with mild to moderate COPD in primary care. Functional exercise capacity was assessed by the six-minute walk test and physical activity was measured with an accelerometer-based activity monitor. Functional exercise capacity was close to normal values. However, the daily physical activity of the patients could be classified as 'sedentary' and 'low active'. No significant correlations were observed between six-minute walk distance (% predicted) and any of the physical activity variables (steps per day, movement intensity during walking, total active time, total walking time, physical activity level, and time spent in moderate physical activity). A discrepancy was found between functional exercise capacity and daily physical activity in patients with mild to moderate COPD recruited and assessed in primary care. We conclude that these variables represent two different concepts. Our results reinforce the importance of measuring daily physical activity in order to fine-tune treatment (i.e. focusing on enhancement of exercise capacity or behavioural change, or both).

A total of 183 (60.4% pregnant Japanese women participated in some form of exercise and 87 (28.7% exercised for 2 hours or more, per week, in the third trimester. Multiple logistic regression analyses indicated that women who set themselves a gestational weight gain target (adjusted odds ratio [AOR] = 8.10, 95% CI [2.82, 23.4], p< .001, were more likely to participate in exercise or sports.

We found a relation-ship between non-participation for 2 hours or more, per week, to being multiparous (AOR = 0.33, 95% CI [0.18, 0.94], p< .001 and the presence of anemia in the second trimester (AOR = 0.51, 95% CI [0.28, 0.94], p = .031. Working status, seasonal differences, concerns about being overweight, and individual dietary nutritional guidance were not related to participation in exercise or sports. While setting a target for gestational weight gain may motivate participation in exercise or sports, women who were multiparous and those who perceived themselves as obese be-fore pregnancy, showed a negative association with participation.

    ACSM Position Stand on Exercise and Physical Activity for Older Adults. Med. Sci. Sports. Exerc., Vol. 30, No. 6, pp. 992-1008, 1998. By the year 2030, the number of individuals 65 yr and over will reach 70 million in the United States alone; persons 85 yr and older will be the fastest growing segment of the population. As more individuals live longer, it is imperative to determine the extent and mechanisms by which exercise and physical activity can improve health, functional capacity, quality of life, and independence in this population. Aging is a complex process involving many variables (e.g., genetics, lifestyle factors, chronic diseases) that interact with one another, greatly influencing the manner in which we age. Participation in regular physical activity (both aerobic and strength exercises) elicits a number of favorable responses that contribute to healthy aging. Much has been learned recently regarding the adaptability of various biological systems, as well as the ways that regular exercise can influence them. Participation in a regular exercise program is an effective intervention/ modality to reduce/prevent a number of functional declines associated with aging. Further, the trainability of older individuals (including octo- and nonagenarians) is evidenced by their ability to adapt and respond to both endurance and strength training. Endurance training can help maintain and improve various aspects of cardiovascular function (as measured by maximal VO2, cardiac output, and arteriovenous O2 difference), as well as enhance submaximal performance. Importantly, reductions in risk factors associated with disease states (heart disease, diabetes, etc.) improve health status and contribute to an increase in life expectancy. Strength training helps offset the loss in muscle mass and strength typically associated with normal aging. Additional benefits from regular exercise include improved bone health and, thus, reduction in risk for osteoporosis; improved

We also conducted a questionnaire survey of their mental health condition before and at every 4 weeks during the intervention. The quantity of physical exercise increased (P exercise intervention did not alter the body weight, but decreased the body fat (Pre, 26.8 ± 0.5%; Post, 24.9 ± 0.5%, P health were significantly raised by the intervention. These results suggest that habitual exercise for 8 weeks was effective for the promotion of physical and mental health in female nursing students.

    Musculoskeletal and cardiovascular deconditioning occurring in long-term spaceflight gives rise to the needs to develop new strategies to counteract these adverse effects. Short-arm centrifuge combined with ergometer has been proposed as a strategy to counteract adverse effects of microgravity. This study sought to investigate whether the combination of short-arm centrifuge and aerobic exercise training have advantages over short-arm centrifuge or aerobic exercise training alone. One week training was conducted by 24 healthy men. They were randomly divided into 3 groups: (1) short-arm centrifuge training, (2) aerobic exercise training, 40 W, and (3) combined short-arm centrifuge and aerobic exercise training. Before and after training, the cardiac pump function represented by stroke volume, cardiac output, left ventricular ejection time, and total peripheral resistance was evaluated. Variability of heart rate and systolic blood pressure were determined by spectral analysis. Physical working capacity was surveyed by near maximal physical working capacity test. The 1-week combined short-arm centrifuge and aerobic exercise training remarkably ameliorated the cardiac pump function and enhanced vasomotor sympathetic nerve modulation and improved physical working capacity by 10.9% (Pcentrifuge nor the aerobic exercise group showed improvements in these functions. These results demonstrate that combined short-arm centrifuge and aerobic exercise training has advantages over short-arm centrifuge or aerobic exercise training alone in influencing several physiologically important cardiovascular functions in humans. The combination of short-arm centrifuge and aerobic exercise offers a promising countermeasure to microgravity.

  6. EFFECTS OF PHYSICAL EXERCISES ON TRIACYLGLYCEROL LEVEL IN SKELETAL MUSCLES IN DIETARY-INDUCED OBESE RATS

    Full Text Available The accumulation of triacylglycerol in peripheral tissues is one of mechanisms of insulin resistance. This paper presents the investigation of the influence of aerobic and anaerobic physical exercises on triacylglycerol level in skeletal muscles and on insulin resistance in dietary-induced obese rats. It is estimated that a high-energy (HE diet causes the accumulation of triacylglycerols in skeletal muscles that leads to high resistance to insulin. Aerobic and anaerobic physical exercises reduce the level of triacylglycerols in skeletal  muscles  and  raise  sensitivity to  insulin  in  obese  rats.  Physical  exercises  raise  the  level  of triacylglycerols in skeletal muscles in standard-diet rats that probably is the adaptation to high energy expenditure, but does not lead to high insulin resistance.

    Objective To assess the impact of exercise referral schemes on physical activity and health outcomes. Design Systematic review and meta-analysis. Data sources Medline, Embase, PsycINFO, Cochrane Library, ISI Web of Science, SPORTDiscus, and ongoing trial registries up to October 2009. We also checked study references. Study selection Design: randomised controlled trials or non-randomised controlled (cluster or individual) studies published in peer review journals. Population: sedentary individuals with or without medical diagnosis. Exercise referral schemes defined as: clear referrals by primary care professionals to third party service providers to increase physical activity or exercise, physical activity or exercise programmes tailored to individuals, and initial assessment and monitoring throughout programmes. Comparators: usual care, no intervention, or alternative exercise referral schemes. Results Eight randomised controlled trials met the inclusion criteria, comparing exercise referral schemes with usual care (six trials), alternative physical activity intervention (two), and an exercise referral scheme plus a self determination theory intervention (one). Compared with usual care, follow-up data for exercise referral schemes showed an increased number of participants who achieved 90-150 minutes of physical activity of at least moderate intensity per week (pooled relative risk 1.16, 95% confidence intervals 1.03 to 1.30) and a reduced level of depression (pooled standardised mean difference −0.82, −1.28 to −0.35). Evidence of a between group difference in physical activity of moderate or vigorous intensity or in other health outcomes was inconsistent at follow-up. We did not find any difference in outcomes between exercise referral schemes and the other two comparator groups. None of the included trials separately reported outcomes in individuals with specific medical diagnoses.Substantial heterogeneity in the quality and nature of the exercise referral

    To determine whether physical activity and blood pressure (BP) response to exercise in early pregnancy are related to resting BP at the end of pregnancy. Understanding physiological BP responses to exercise during pregnancy will help in improving BP profile and guiding exercise recommendations in pregnant women. Maternal physical activity, cardiorespiratory fitness (VO2peak) and BP (systolic and diastolic) at rest and during exercise (submaximal and relative response) were assessed at 16 weeks of gestation in 61 normotensive pregnant women. BP at 36 weeks of gestation and obstetrical outcomes were collected from maternal charts. Related to resting DBP at 16 weeks (r =  -0.28, P = 0.028), total energy expenditure spend at any physical activity in early pregnancy was also associated with resting SBP at 36 weeks (r =  -0.27, P = 0.038). On the contrary, although related to VO2peak (r =  -0.57, P sports and exercise (r =  -0.29, P = 0.024), the relative SBP response to exercise at 16 weeks was not associated with resting BP at 36 weeks. Strongly associated with resting BP at 16 weeks and also with total energy expenditure, submaximal BP response to exercise at 16 weeks was related to resting SBP and DBP at 36 weeks (r = 0.41, P = 0.001 and r = 0.26, P = 0.051, respectively). In normotensive women, physical activity performed in early pregnancy appears to slightly modulate resting BP in early and late pregnancy. However, further investigations are needed to determine which physical activity-related parameter in response to exercise best predicts BP variations during pregnancy.

    Full Text Available Abstract Background To analyze the factors associated with regular physical exercise and routine consumption of fruits and vegetables, and both healthy behaviors among Mexican older adults. Methods We conducted a secondary data analysis of the baseline data (2014 of the Study on Obesity, Sarcopenia and Fragility in older adults affiliated with the Mexican Institute of Social Security. The study included 948 adults who were ≥60 years of age. Multiple Poisson regression was performed. Results Routine consumption of fruits and vegetables was reported by 53.8 % of older adults, 42.7 % reported engaging in regular physical exercise and 23.1 % reported participating in both types of healthy behaviors. Women, adults with a stable income, those with a self-perception of good health and those with a history of physical exercise at the age of 50 years had an increased likelihood of engaging in healthy eating and regular physical activity. Conclusions Many older adults do not routinely consume fruits and vegetables or engage in regular physical exercise despite the fact that most have a fixed income and a social network. It is relevant to conduct research-based interventions that take into account the contextual factors to promote healthy behaviors.

    Lifestyle in general (nutrition, exercise, smoking habits), besides the genetic predisposition, is known to be a strong predictor for the development of diabetes. Exercise in particular is not only useful in improving glycaemia by lowering insulin resistance and positively affect insulin secretion, but to reduce cardiovascular risk.To gain substantial health benefits a minimum of 150 min of moderate or vigorous intense aerobic physical activity and muscle strengthening activities per week are needed. The positive effect of training correlates directly with the amount of fitness gained and lasts only as long as the fitness level is sustained. The effect of exercise is independent of age and gender. It is reversible and reproducible.Based on the large evidence of exercise referral and prescription the Austrian Diabetes Associations aims to implement the position of a "physical activity adviser" in multi-professional diabetes care.

    Full Text Available In animals, physical activity has been shown to induce functional and structural changes especially in the hippocampus and to improve memory, probably by upregulating the release of neurotrophic factors. In humans, results on the effect of acute exercise on memory are inconsistent so far. Therefore, the aim of the present study was to assess the effects of a single bout of physical exercise on memory consolidation and the underlying neuroendocrinological mechanisms in young adults. Participants encoded a list of German-Polish vocabulary before exercising for 30 minutes with either high intensity or low intensity or before a relaxing phase. Retention of the vocabulary was assessed 20 minutes after the intervention as well as 24 hours later. Serum BDNF and salivary cortisol were measured at baseline, after learning, and after the intervention. The high-intensity exercise group showed an increase in BDNF and cortisol after exercising compared to baseline. Exercise after learning did not enhance the absolute number of recalled words. Participants of the high-intensity exercise group, however, forgot less vocabulary than the relaxing group 24 hours after learning. There was no robust relationship between memory scores and the increase in BDNF and cortisol, respectively, suggesting that further parameters have to be taken into account to explain the effects of exercise on memory in humans.

    Although much evidence supports the hypothesis that cognitive function and physical function are interrelated, it is unclear whether cognitive decline with mild cognitive impairment influences trainability of physical performance in exercise intervention. The purpose of this study was to examine the association between cognitive function at baseline and change in physical performance after exercise intervention in older adults with mild cognitive impairment. Forty-four older adults diagnosed with mild cognitive impairment based on the Peterson criteria (mean age 74.8 years) consented to and completed a 6-month twice weekly exercise intervention. The Timed Up and Go (TUG) test was used as a measure of physical performance. The Mini-Mental State Examination (MMSE), Trail Making Test Part B, Geriatric Depression Scale, baseline muscle strength of knee extension, and attendance rate of intervention, were measured as factors for predicting trainability. In the correlation analysis, the change in TUG showed modest correlations with attendance rate in the exercise program (r = -0.354, P = 0.027) and MMSE at baseline (r = -0.321, P = 0.034). A multiple regression analysis revealed that change in TUG was independently associated with attendance rate (β = -0.322, P = 0.026) and MMSE score (β = -0.295, P = 0.041), controlling for age and gender. General cognitive function was associated with improvements in physical performance after exercise intervention in subjects with mild cognitive impairment. Further research is needed to examine the effects of exercise programs designed to address cognitive obstacles in older adults with mild cognitive impairment.

    2017-09-01

    Full Text Available Scientific arguments in favour of applying physical exercise as an intervention on "aging" insists on relying on the biological concept of health. Considering the hegemony of this concept in physical education, the present study questions in what extent it must be accepted that the relationship between health/aging remains summarized in the mere search for maintaining physiological capabilities? The aim was to analyse the problematizations on the relationship between health and exercise in a group of physically active women from the city of Recife, Pernambuco, Brazil, in the context of aging process. Forty-five amateur bodybuilders were selected utilizing the sample snowball technique. They answered an interview guide with pictures according to the photo elicitation technique, individually. It was utilized the speech analysis proposed by Foucault. The group understands the relationship health/aging as a way to build identities, overcoming the negative perception of old age as vital and negative process. The fear of aging denotes the presence of self-centred healthcare practices carried over the years. Physical exercise plays a role that transcends the mere control of biological variables, being a resource to strengthen the experience to look and feel younger.

    Within the UK, differences exist between physical therapists' use of exercise for patients with knee osteoarthritis (OA) and recent exercise recommendations. This may be explained by their underlying attitudes and beliefs. We aimed to describe UK physical therapists' attitudes and beliefs regarding exercise and knee OA, and understand and explain them. A survey was mailed to 2,000 UK-based chartered physical therapists that included 23 attitude statements derived from recently published recommendations. Semistructured telephone interviews were conducted with a purposeful sample of questionnaire respondents (n = 24), and were recorded and analyzed thematically. The questionnaire response rate was 58% (n = 1,152); 538 respondents reported treating a patient with knee OA in the last 6 months. The survey highlighted uncertainty about potential benefits of exercise for knee OA: only 56% largely/totally agreed that knee problems are improved by local exercise. Although exercise adherence was deemed important, it was seen as the patient's, not the therapist's, responsibility. Interviews revealed an underlying biomedical model of care of knee pain, with knee OA viewed as a progressive degenerative condition. A paternalistic treatment approach was evident. Health care systems presented a number of barriers to best practice, including limited opportunity to provide followup. Although the attitudes and beliefs of physical therapists may help to explain differences between current practice and recent exercise recommendations, the wider health care system also plays a part. Further research is needed to support meaningful shifts in physical therapy care in line with the best practice recommendations.

    Full Text Available The prevalence of smartphones and their adequate computer skills can be used for detecting everyday physical exercises. Acquired information on performed exercises can be used in the field of Health Informatics. For identification of particular physical activity a number of sensors and their repositioning during exercises are needed. This paper presents a way to classify the type of exercise using only triaxial built-in accelerometric sensor in the smartphone. The smartphone itself is free to move inside the subject pocket. The problem of using a number of sensors and their repositioning during exercise is solved by raw signal filtering and by defining a set of signal descriptors. Nine characteristic exercises have been analyzed for different programs and levels of exercise. To filter the raw accelerometer signal a low-pass 10-th order Butterworth filter is used. The filtered signals are described in terms of five descriptors which are used to train an artificial neural network (ANN. Classification of the type of exercise is performed using ANN with an error of 0.7%. Some exercises can be performed with only left or right leg. The classification accuracy of proposed approach is tested in a way that the smartphone was always in the subject's right pocket even when the exercise is performed using left leg only.

    To investigate the effectiveness of an exercise intervention for decreasing fatigue severity and increasing physical activity in individuals with pulmonary arterial hypertension (PAH). A small, phase 2 randomized clinical trial of the effect of aerobic exercise training on fatigue severity and physical activity in patients with idiopathic or PAH associated with other conditions was conducted. Twenty-four patients with PAH (24 female; age: 54.4 ± 10.4 years; BMI: 30.8 ± 7.2 kg/m(2)) participated in the study. A convenience sample was recruited in which 9% (28 of 303) of screened patients were enrolled. The project was carried out in a clinical pulmonary rehabilitation clinic during existing pulmonary rehabilitation program sessions. Patients with PH were randomized into a 10-week program that consisted of patient education only or patient education plus an aerobic exercise-training regimen. Both groups received 20 lectures, two per week over the 10-weeks, on topics related to PAH and its management. The aerobic exercise training consisted of 24-30 sessions of treadmill walking for 30-45 min per session at an intensity of 70-80% of heart rate reserve, three days per week over the 10 weeks. After 10-weeks of intervention, patients receiving aerobic exercise training plus education reported routinely engaging in higher levels of physical activity (p decrease in fatigue severity (p = 0.03). Patients in the education only group did not report changes in fatigue severity or participation in physical activity. The 10-week aerobic exercise training intervention resulted in increased physical activity and decreased fatigue in individuals with PAH. ClinicalTrials.gov Identifier: NCT00678821.

    The aim of this work was to study the effect of gamma radiation and submaximal physical exercise on the concentration of final products of anaerobic glycolytic pathway in erythrocytes of healthy men. Twenty one men aged 20-22 were examined. They underwent physical exercise at doses of 2 w/kg body weight for 15 min. Erythrocytes were taken in the rest and after physical exercise and were exposed to gamma radiation (500 Gy doses) from 60 Co source. The concentration of pyruvate was estimated by Fermognost tests and the concentration of lactate by Boehringer Mannheim tests. The submaximal physical exercise was found to cause a significantly increased concentration of pyruvate and lactate in the non-radiated and irradiated erythrocytes. Gamma radiation at 500 Gy dose was found to increase concentration of pyruvate in erythrocytes (in the rest and after physical exercise) with simultaneous decrease of lactate concentration.

    It is well known that physical exercise is important to promote physical and cognitive health in older population. However, inconsistent research findings were shown regarding exercise intensity, particularly on whether low-intensity exercise (1.5 metabolic equivalent tasks (METs) to 3.0 METs) can improve physical and cognitive health of older adults. This systematic review aimed to fill this research gap. The objective of this study is to conduct a systematic review of the effectiveness of low-intensity exercise interventions on physical and cognitive health of older adults. Published research was identified in various databases including CINAHL, MEDLINE, PEDro, PubMed, Science Direct, SPORTDiscus, and Web of Science. Research studies published from January 01, 1994 to February 01, 2015 were selected for examination. Studies were included if they were published in an academic peer-reviewed journal, published in English, conducted as randomized controlled trial (RCT) or quasi-experimental studies with appropriate comparison groups, targeted participants aged 65 or above, and prescribed with low-intensity exercise in at least one study arm. Two reviewers independently extracted the data (study, design, participants, intervention, and results) and assessed the quality of the selected studies. Fifteen studies met the inclusion criteria. Quality index ranged from 15 to 18 mean = 18.3 with a full score of 28, indicating a moderate quality. Most of the outcomes reported in these studied were lower limb muscle strength ( n  = 9), balancing ( n  = 7), flexibility ( n  = 4), and depressive symptoms ( n  = 3). Out of the 15 selected studies, 11 reported improvement in flexibility, balancing, lower limb muscle strength, or depressive symptoms by low-intensity exercises. The current literature suggests the effectiveness of low-intensity exercise on improved physical and cognitive health for older adults. It may be a desired intensity level in promoting

    The effects of regular exercise versus a single bout of exercise on cognition, anxiety, and mood were systematically examined in healthy, sedentary young adults who were genotyped to determine brain-derived neurotrophic factor (BDNF) allelic status (i.e., Val-Val or Val66Met polymorphism). Participants were evaluated on novel object recognition (NOR) memory and a battery of mental health surveys before and after engaging in either (a) a 4-week exercise program, with exercise on the final test day, (b) a 4-week exercise program, without exercise on the final test day, (c) a single bout of exercise on the final test day, or (d) remaining sedentary between test days. Exercise enhanced object recognition memory and produced a beneficial decrease in perceived stress, but only in participants who exercised for 4 weeks including the final day of testing. In contrast, a single bout of exercise did not affect recognition memory and resulted in increased perceived stress levels. An additional novel finding was that the improvements on the NOR task were observed exclusively in participants who were homozygous for the BDNF Val allele, indicating that altered activity-dependent release of BDNF in Met allele carriers may attenuate the cognitive benefits of exercise. Importantly, exercise-induced changes in cognition were not correlated with changes in mood/anxiety, suggesting that separate neural systems mediate these effects. These data in humans mirror recent data from our group in rodents. Taken together, these current findings provide new insights into the behavioral and neural mechanisms that mediate the effects of physical exercise on memory and mental health in humans.

    To systematically examine the amount and type of physical exercise that might reduce the future risk of dementia in community-living older people. Six-year observational study. All the Elderly Health Centers (EHCs) of the Department of Health in Hong Kong. A total of 15,589 community-living Chinese aged 65 years and older with no history of stroke, clinical dementia, or Parkinson disease when they completed health assessment at the EHCs in the first 6 months of 2005. Self-reported habitual physical exercise patterns, including the frequency, duration, and type of exercise, at baseline and Year 3 were analyzed. The study outcome was incident dementia in 6 years. Dementia was defined by presence of clinical dementia in accordance with the 10th revision of the International Statistical Classification of Diseases and Related Health Problems or Clinical Dementia Rating of 1 to 3. Both the cognitively stable and incident groups reported exercising a median of 7 days per week and 45 minutes per day at baseline and Year 3. The former practiced aerobic and mind-body exercises more at baseline and Year 3, whereas the latter practiced stretching and toning exercises more. The odds ratio for dementia remained significant for aerobic (0.81; 95% confidence interval 0.68-0.95; P = .01) and mind-body exercises (0.76; 0.63-0.92; P = .004) after excluding participants who developed dementia within 3 years after baseline and adjusting for important potential confounders, such as age, gender, educational level, and physical and psychiatric comorbidities. Although physical exercise is widely promoted as a nonpharmacological intervention for dementia prevention, not all types of exercise appear to be useful in reducing risk of dementia in older people. Our findings suggest that daily participation in aerobic and mind-body but not stretching and toning exercises might protect community-living older adults from developing dementia.

    Grounded in self-determination theory (Deci & Ryan, 2000), the purpose of this work was to examine effects of the content and motivation of adults' exercise goals on objectively assessed moderate-to-vigorous physical activity (MVPA). After reporting the content and motivation of their exercise goals, 101 adult participants (Mage = 38.79 years; SD = 11.5) wore an ActiGraph (GT1M) accelerometer for seven days. Accelerometer data were analyzed to provide estimates of engagement in MVPA and bouts of physical activity. Goal content did not directly predict behavioral engagement; however, mediation analysis revealed that goal content predicted behavior via autonomous exercise motivation. Specifically, intrinsic versus extrinsic goals for exercise had a positive indirect effect on average daily MVPA, average daily MVPA accumulated in 10-min bouts and the number of days on which participants performed 30 or more minutes of MVPA through autonomous motivation. These results support a motivational sequence in which intrinsic versus extrinsic exercise goals influence physical activity behavior because such goals are associated with more autonomous forms of exercise motivation.

    The purpose of this study was to determine the effectiveness of enhancing support for physical activity counselling and exercise participation at diabetes centres in Nova Scotia on physical activity and exercise behaviours and clinical outcomes in patients with type 2 diabetes mellitus. In all, 180 patients at 8 diabetes centres participated in this observational study. A range of enhanced supports for exercise were offered at these centres. A kinesiologist was added to the diabetes care team to primarily provide extra physical activity counselling and exercise classes. Patient physical activity and exercise levels, efficacy perceptions and mean glycated hemoglobin (A1C) were evaluated at baseline and 6 months. We compared changes in these variables for patients who participated in the enhanced supports versus patients who did not. Participants who attended exercise classes (n=46), increased moderate physical activity by 27% and doubled resistance exercise participation (1.0±1.8 to 2.0±2.1 days per week) whereas those who did not attend exercise classes (n=49) reduced moderate physical activity by 26% and did not change resistance exercise participation (interactions, p=0.04 and p=0.07, respectively). Patients who received resistance band instruction (n=15) from a kinesiologist had reductions in A1C (from 7.5±1.4 to 7.1±1.2; p=0.04), whereas other subgroups did not have significant changes in A1C. Offering enhanced support for exercise at diabetes centres produced improvements in physical activity and exercise in type 2 diabetes patients. Resistance band instruction from a kinesiologist combined with participating in a walking and resistance training program improved glycemic control, which underscores the importance of including exercise professionals in diabetes management.

    Full Text Available INTRODUCTION: Physical exercise has been associated with improvement of quality of live (QoL, but its effect among the elderly with depression and Alzheimer's disease (AD is still unclear. This systematic review evaluated randomized and controlled studies about the effect of physical exercise on QoL of older individuals with a clinical diagnosis of depression and AD.METHODS:We searched PubMed, ISI, SciELO and Scopus from December 2011 to June 2013 using the following keywords: physical exercise, quality of life, elderly, depression, Alzheimer's disease. Only six studies met inclusion criteria: two examined patients with AD and four, patients with depression.RESULTS: The studies used different methods to prescribe exercise and evaluate QoL, but all had high quality methods. Findings of most studies with individuals with depression suggested that exercise training improved QoL, but studies with patients with AD had divergent results.CONCLUSIONS: Although different methods were used, results suggested that physical exercise is an effective non-pharmacological intervention to improve the QoL of elderly individuals with depression and AD. Future studies should investigate the effect of other factors, such as the use of specific scales for the elderly, controlled exercise prescriptions and type of control groups.

    Patients with fibromyalgia have diminished levels of physical fitness, which may lead to functional disability and exacerbating complaints. Multidisciplinary treatment comprising cognitive-behavioural therapy (CBT) and exercise training has been shown to be effective in improving physical fitness. However, due to the high drop-out rates and large variability in patients' functioning, it was proposed that a tailored treatment approach might yield more promising treatment outcomes. High-risk fibromyalgia patients were randomly assigned to a waiting list control group (WLC) or a treatment condition (TC), with the treatment consisting of 16 twice-weekly sessions of CBT and exercise training tailored to the patient's cognitive-behavioural pattern. Physical fitness was assessed with two physical tests before and 3 months after treatment and at corresponding intervals in the WLC. Treatment effects were evaluated using linear mixed models. The level of physical fitness had improved significantly in the TC compared with the WLC. Attrition rates were low, effect sizes large and reliable change indices indicated a clinically relevant improvement among the TC. A tailored multidisciplinary treatment approach for fibromyalgia consisting of CBT and exercise training is well tolerated, yields clinically relevant changes, and appears a promising approach to improve patients' physical fitness.

    Nowadays, physical exercise and sports activities are regarded as the best means for people to keep fit and boost their health. In Vietnam, exercising on a daily basis is still underappreciated as twothirds of the population only exercise at trivial or low levels. Based on applying the baseline category logit model, we conduct an analysis to figure out the factors affecting people’s level of exercise. The findings show that males tend to engage in physical activities more than females, with t...

    The aim of the present systematic review is to provide an up-to-date analysis of the research on the effects of exercise programs on heart rate variability (HRV) in individuals with type 2 diabetes mellitus (T2DM). An electronic search of the literature (PubMed, PEDro and Web of Science) was performed. "HRV", "heart rate variability", "exercise", "physical" and "diabetes" were the terms used for article retrieval. Lastly, 15 articles were selected. PRISMA methodology was employed and data were extracted according to the PICOS approach. Although HRV is not routinely measured in the management of T2DM, it is an important measure due to its relation with mortality and diabetic neuropathy. Physical exercise has become a therapy for T2DM, because it improves physical fitness and functional capacity, enhances metabolic control and insulin sensitivity, reduces inflammatory markers and neuropathy symptoms and can increase the regenerative capacity of cutaneous axons, slowing or preventing neuropathy progression. However, it is not clear to what extent physical exercise can improve HRV in this population. Participation in the 15 selected studies was similar in men and women (48.01% men and 51.99% women). All the intervention programs included aerobic training, and it was complemented by strength training in four studies. Duration of physical exercise sessions ranged between 30 and 75 min, the frequency being between 2 and 7 days/week. Statistically significant improvements in groups with diabetes, relative to baseline, were observed in nine studies. More than 3 days per week of aerobic training, complemented by strength training, during at least 3 months seems to improve HRV in T2DM. Weekly frequency might be the most important factor to improve HRV. These aspects could help to design better programs based in scientific evidence, incorporating HRV as an important variable associated with diabetic neuropathy and mortality.

    The al-Andalus physical activity intervention study is a randomised control trial to investigate the effectiveness of a land- and water-based exercise intervention for reducing the overall impact of fibromyalgia (primary outcome), and for improving tenderness and pain-related measures, body composition, functional capacity, physical activity and sedentary behaviour, fatigue, sleep quality, health-related quality of life, and cognitive function (secondary outcomes) in women with fibromyalgia. One hundred eighty women with fibromyalgia (age range: 35-65 years) will be recruited from local associations of fibromyalgia patients in Andalucía (Southern Spain). Patients will be randomly assigned to a usual care (control) group (n = 60), a water-based exercise intervention group (n = 60) or a land-based exercise intervention group (n = 60). Participants in the usual care group will receive general physical activity guidelines and participants allocated in the intervention groups will attend three non-consecutive training sessions (60 min each) per week during 24 weeks. Both exercise interventions will consist of aerobic, muscular strength and flexibility exercises. We will also study the effect of a detraining period (i.e., 12 weeks with no exercise intervention) on the studied variables. Our study attempts to reduce the impact of fibromyalgia and improve patients' health status by implementing two types of exercise interventions. Results from this study will help to assess the efficacy of exercise interventions for the treatment of fibromyalgia. If the interventions would be effective, this study will provide low-cost and feasible alternatives for health professionals in the management of fibromyalgia. Results from the al-Andalus physical activity intervention will help to better understand the potential of regular physical activity for improving the well-being of women with fibromyalgia.

    Full Text Available Background: Physical fitness determines the level of human health. A good physical fitness can be achieved if conducted with a balance and active physical fitness. The aims of this study was to elucidate the effect of balanced physical exercise on physical fitness, endorphin levels, and malondialdehyde (MDA levels. Methods: This study was a true experimental with pretest-posttest control group design using 24 students of IKIP PGRI Denpasar. Selected samples divided into two groups: the control group given conventional physical training (P0 and the treatment group given balanced physical training (P1. Physical fitness tests was performed using Cooper method and blood sampling was done to evaluate the level of endorphins and MDA before (pre test and after (post test treatment of 8 weeks. The data of endorphin and MDA levels were analyzed using independent T test. Whereas, the physical fitness was analyzed using Mann-Whitney U test. Results: Physical fitness of the group given a balanced physical training was significantly higher compare to the group given a conventional physical training (p < 0.05. Balanced physical training was proven to enhance physical fitness as measured by the Cooper method better than conventional physical training. In contrast, the levels of endorphins of the balanced physical training group did not different with the conventional physical training group (p > 0.05. Levels of MDA of balanced physical training group also did not different with the conventional physical training group (p > 0.05. Conclusions: balanced physical training can maintain physical fitness of people and improve the health and quality of life.

    In negotiating stairs, low foot clearance increases the risk of tripping and a fall. Foot clearance may be related to physical fitness, which differs between active and sedentary participants, and be acutely affected by exercise. Impaired stair negotiation could be an acute response to exercise. Here we determined acute changes in foot clearances during stair walking in sedentary (n = 15) and physically active older adults (n = 15) after prolonged exercise. Kinematic data were acquired during negotiation with a 3-steps staircase while participants walked at preferred speed, before and after 30 min walking at preferred speed and using a treadmill. Foot clearances were compared before and after exercise and between the groups. Sedentary older adults presented larger (0.5 cm for lead and 2 cm for trail leg) toe clearances in ascent, smaller (0.7 cm) heel clearance in the leading foot in descent, and larger (1 cm) heel clearance in the trailing foot in descent than physically active. Sedentary older adults negotiate stairs in a slightly different way than active older adults, and 30 min walking at preferred speed does not affect clearance in stair negotiation.

    In the context of sedentary middle-aged adults, the present study examined the relationships among domain-specific and global levels of self-esteem over the course of a 20-week exercise program. Additionally, the roles played by physical fitness, body composition, self-efficacy, and exercise participation as possible contributors to changes in physical self-worth were examined. Significant improvements in self-esteem at all levels were discovered with global esteem, physical self-worth, and perceptions of physical condition and attractive body increasing. Tests of the hierarchical structure of self-esteem showed greater improvements in physical condition and physical self-worth than global esteem and the relationships between global esteem and subdomain levels were shown to be mediated by physical self-worth. Hierarchical regression analyses showed changes in ratings of importance to have little impact on changes in physical self-worth. Both changes in efficacy and aerobic capacity were demonstrated to account for modest but significant variation in physical self-esteem. Results are discussed in terms of contemporary models of self-esteem, potential mediators of exercise effects on esteem, and the need to measure the constructs of interest appropriately.

    Patients with advanced stage non-small cell lung cancer (NSCLC) or small cell lung cancer (SCLC) often experience multidimensional impairments, affecting quality of life during their course of disease. In lung cancer patients with operable disease, several studies have shown that exercise has a positive impact on quality of life and physical functioning. There is limited evidence regarding efficacy for advanced lung cancer patients undergoing palliative treatment. Therefore, the POSITIVE study aims to evaluate the benefit of a 24-week exercise intervention during palliative treatment in a randomized controlled setting. The POSITIVE study is a randomized, controlled trial investigating the effects of a 24-week exercise intervention during palliative treatment on quality of life, physical performance and immune function in advanced, non-operable lung cancer patients. 250 patients will be recruited in the Clinic for Thoracic Diseases in Heidelberg, enrolment begun in November 2013. Main inclusion criterion is histologically confirmed NSCLC (stage IIIa, IIIb, IV) or SCLC (Limited Disease-SCLC, Extensive Disease-SCLC) not amenable to surgery. Patients are randomized into two groups. Both groups receive weekly care management phone calls (CMPCs) with the goal to assess symptoms and side effects. Additionally, one group receives a combined resistance and endurance training (3x/week). Primary endpoints are quality of life assessed by the Functional Assessment of Cancer Therapy for patients with lung cancer (FACT-L, subcategory Physical Well-Being) and General Fatigue measured by the Multidimensional Fatigue Inventory (MFI-20). Secondary endpoints are physical performance (maximal voluntary isometric contraction, 6-min walk distance), psychosocial (depression and anxiety) and immunological parameters and overall survival. The aim of the POSITIVE trial is the evaluation of effects of a 24-week structured and guided exercise intervention during palliative treatment stages

  20. Monitoring Change of Body Fluid during Physical Exercise using Bioimpedance Spectroscopy and Finite Element Simulations

    Full Text Available Athletes need a balanced body composition in order to achieve maximum performance. Especially dehydration reduces power and endurance during physical exercise. Monitoring the body composition, with a focus on body fluid, may help to avoid reduction in performance and other health problems.For this, a potential measurement method is bioimpedance spectroscopy (BIS. BIS is a simple, non-invasive measurement method that allows to determine different body compartments (body fluid, fat, fat-free mass. However, because many physiological changes occur during physical exercise that can influence impedance measurements and distort results, it cannot be assumed that the BIS data are related to body fluid loss alone.To confirm that BIS can detect body fluid loss due to physical exercise, finite element (FE simulations were done. Besides impedance, also the current density contribution during a BIS measurement was modeled to evaluate the influence of certain tissues on BIS measurements.Simulations were done using CST EM Studio (Computer Simulation Technology, Germany and the Visible Human Data Set (National Library of Medicine, USA. In addition to the simulations, BIS measurements were also made on athletes. Comparison between the measured bioimpedance data and simulation data, as well as body weight loss during sport, indicates that BIS measurements are sensitive enough to monitor body fluid loss during physical exercise.doi:10.5617/jeb.178 J Electr Bioimp, vol. 2, pp. 79-85, 2011

    Full Text Available This study determined whether performing a single moderate- or vigorous-intensity exercise bout impacts daily physical activity energy expenditure (PAEE, by accelerometer. Overweight/obese postmenopausal women underwent a 5-month caloric restriction and moderate- (n=18 or vigorous-intensity (n=18 center-based aerobic exercise intervention. During the last month of intervention, in women performing moderate-intensity exercise, PAEE on days with exercise (577.7±219.7 kcal⋅d−1 was higher (P=.011 than on days without exercise (450.7±140.5 kcal⋅d−1; however, the difference (127.0±188.1 kcal⋅d−1 was much lower than the energy expended during exercise. In women performing vigorous-intensity exercise, PAEE on days with exercise (450.6±153.6 kcal⋅d−1 was lower (P=.047 than on days without exercise (519.2±127.4 kcal⋅d−1. Thus, women expended more energy on physical activities outside of prescribed exercise on days they did NOT perform center-based exercise, especially if the prescribed exercise was of a higher intensity.

    We studied the relationship between smoking and exercise among physical education teachers in Turkey. An online questionnaire was used to collect data. The responses of 1,995 teachers who completed the questionnaire were evaluated. The mean age of the participants was 31.0 +/- 4.7 years; 67.4% of the participants were male. The smoking rate was 65.2%. The mean age of onset of smoking was 16.6 +/- 2.6 years. The age of starting smoking increased with higher parental education level. There were no differences between smokers and nonsmokers with respect to gender. Of smokers, 51.2% were married; 52.4% were in the 30-39 year old age group. The most common reasons for starting smoking were the influence of friends and emulation. The most common reason for trying to quit smoking among men was future health concerns and among women was current health concerns. We found smoking was less common among participants who exercised regularly. The level of nicotine dependence was significantly lower among participants who exercised regularly compared to those who did not. This study suggests physical education teachers, who are role models for their students, have a high smoking rate. We believe urgent action is needed to reduce the smoking rate and increase the quit rate among physical education teachers.

    Randomized controlled trial of physical exercise and dopaminergic agonist in persons with spinal cord injury and periodic leg movement (PLM). The objective of the present study was to compare the effectiveness of physical exercise and of a dopaminergic agonist in reducing the frequency of PLM. Centro de Estudos em Psicobiologia e Exercício. Universidade Federal de São Paulo, Brazil. A total of 13 volunteers (mean age: 31.6+/-8.3 years) received L-DOPA (200 mg) and benserazide (50 mg) 1 h before sleeping time for 30 days and were then submitted to a physical exercise program on a manual bicycle ergometer for 45 days (3 times a week). Both L-DOPA administration (35.11-19.87 PLM/h, P<0.03) and physical exercise (35.11-18.53 PLM/h, P<0.012) significantly reduced PLM; however, no significant difference was observed between the two types of treatment. The two types of treatment were found to be effective in the reduction of PLM; however, physical exercise is indicated as the first treatment approach, while dopaminergic agonists or other drugs should only be recommended for patients who do not respond to this type of treatment.

    Due to the currently growing rate of obesity, it is important to maintain good control of food intake. The main purpose of the present study is to determine the influence of physical exercise on appetite, changes in hormone concentrations, and changes in certain neuronal regions. To achieve this, a literature search was conducted using different data bases. The results show how exercise produces changes in the appetite perception, in the amount of energy intake, and in different weight-control related hormones, as well as in specific neuronal responses. In conclusion, it can be shown that exercise leads to changes in appetite, hunger, and energy intake. In addition, exercise decreases the ghrelin levels and increases concentrations of leptin. Likewise, it is shown how physical exercise alters the responses of certain neuronal regions after visualizing specific food elements decreasing so the appetite or the intake of them.

    Orthorexia nervosa is described as an exaggerated fixation on healthy food. It is unclear whether students in health-oriented academic programs, highly focused on physical exercise, are more prone to develop orthorexia nervosa than students in other educational areas. The aim was to compare health status, physical activity, and frequency of orthorexia nervosa between university students enrolled in an exercise science program (n = 118) or a business program (n = 89). The students completed the Short Form-36 Health Survey (SF-36), the International Physical Activity Questionnaire (IPAQ), and ORTO-15, which defines orthorexia nervosa as a sensitive and obsessive behavior towards healthy nutrition. The SF-36 showed that exercise science students scored worse than business students regarding bodily pain (72.8 vs. 82.5; p = 0.001), but better regarding general health (83.1 vs. 77.1; p = 0.006). Of 188 students, 144 (76.6%) had an ORTO-15 score indicating orthorexia nervosa, with a higher proportion in exercise science students than in business students (84.5% vs. 65.4%; p = 0.002). Orthorexia nervosa in combination with a high level of physical activity was most often seen in men in exercise science studies and less often in women in business studies (45.1% vs. 8.3%; p orthorexia nervosa in exercise science students may cause problems in the future, since they are expected to coach others in healthy living. Our findings may be valuable in the development of health-oriented academic programs and within student healthcare services. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Neurocognitive dysfunction associated with bipolar disorder (BD) is pervasive, persistent across illness phases, and is demonstrated to predispose and portend psychosocial impairment. Moreover, no approved therapies for various phases of BD have been shown to reliably improve any dimension of neurocognitive performance. In this article, we emphasize that aerobic physical exercise is a viable neurocognitive-enhancing adjunctive treatment for patients with BD. The overarching aim of this review is to emphasize that aerobic physical exercise is a viable neurocognitive-enhancing adjunctive treatment for patients with BD. We conducted PubMed and Google Scholar searches of all English-language articles published between January 1966 and February 2010 using the search terms bipolar disorder, major depressive disorder, depression, exercise, and physical activity cross-referenced with each other and the following terms: cognition, executive function, learning, memory, attention, emotion, and behavior. Articles selected for review were based on adequacy of sample size, use of standardized experimental procedures, validated assessment measures, and overall quality. Available studies have documented an array of persisting neurocognitive deficits across disparate bipolar populations. Abnormalities in verbal working memory are highly replicated; deficits in executive function, learning, attention, and processing speed are also a consistent abnormality. The effect sizes of neurocognitive deficits in BD are intermediate between those reported in schizophrenia and major depressive disorder. Several original reports and reviews have documented the neurocognitive-enhancing effects of aerobic exercise in the general population as well as across diverse medical populations and ages. Proposed mechanisms involve nonexclusive effects on neurogenesis, neurotrophism, immunoinflammatory systems, insulin sensitivity, and neurotransmitter systems. Each of these effector systems are implicated

  8. A Pilot Test of the Additive Benefits of Physical Exercise to CBT for OCD.

    The majority of "responders" to first-line cognitive-behavioural therapy (CBT) and pharmacological treatments for obsessive-compulsive disorder (OCD) are left with residual symptoms that are clinically relevant and disabling. Therefore, there is pressing need for widely accessible efficacious alternative and/or adjunctive treatments for OCD. Accumulating evidence suggests that physical exercise may be one such intervention in the mood and anxiety disorders broadly, although we are aware of only two positive small-scale pilot studies that have tested its clinical benefits in OCD. This pilot study aimed to test the feasibility and preliminary efficacy of adding a structured physical exercise programme to CBT for OCD. A standard CBT group was delivered concurrently with a 12-week customized exercise programme to 11 participants. The exercise regimen was individualized for each participant based on peak heart rate measured using an incremental maximal exercise test. Reports of exercise adherence across the 12-week regimen exceeded 80%. A paired-samples t-test indicated very large treatment effects in Yale-Brown Obsessive-Compulsive Scale scores from pre- to post-treatment in CBT group cohorts led by expert CBT OCD specialists (d = 2.55) and junior CBT clinician non-OCD specialists (d = 2.12). These treatment effects are very large and exceed effects typically observed with individual and group-based CBT for OCD based on leading meta-analytic reviews, as well as previously obtained treatment effects for CBT using the same recruitment protocol without exercise. As such, this pilot work demonstrates the feasibility and significant potential clinical utility of a 12-week aerobic exercise programme delivered in conjunction with CBT for OCD.

    This article examines the nature of exercise addiction. It presents a broad, congruent and discerning narrative literature review with the aim of providing a deeper understanding of the condition 'exercise addiction', including symptoms and options for treatment. In addition, guidelines are provided with respect to 'healthy' levels of exercise. Criteria used for determining the eligibility of studies evaluated in the review included the provision of relevant information in studies identified using pertinent search terms. The review highlights some of the key distinctions between healthy levels of exercise and exercise addiction. The findings suggest that an individual who is addicted to exercise will continue exercising regardless of physical injury, personal inconvenience or disruption to other areas of life including marital strain, interference with work and lack of time for other activities. 'Addicted' exercisers are more likely to exercise for intrinsic rewards and experience disturbing deprivation sensations when unable to exercise. In contrast, 'committed' exercisers engage in physical activity for extrinsic rewards and do not suffer severe withdrawal symptoms when they cannot exercise. Exercisers must acquire a sense of life-balance while embracing an attitude conducive to sustainable long-term physical, psychological and social health outcomes. Implementation of recommendations by the Canadian Society for Exercise Physiology, which states that all apparently healthy adults between 18 and 64 years of age should accumulate at least 150 minutes of moderate (5 or 6 on a scale of 0-10) to vigorous (7 or 8 on a scale of 0-10) intensity aerobic physical activity per week in bouts of 10 minutes or more, also expressed as 30 minutes per day distributed over 5 days per week, would be a good start.

    Pregnant women without medical contraindications should accumulate 30 min of moderate exercise on most days of the week, yet many pregnant women do not exercise at recommended levels. The purpose the study was to examine barriers to leisure-time physical activity (LTPA) and investigate barrier and exercise self-efficacy as predictors of self-reported LTPA during pregnancy. Pregnant women (n = 160) completed questionnaires eliciting barriers to LTPA, measures of exercise and barrier self-efficacy, and 6-week LTPA recall at gestational weeks 18, 24, 30, and 36. A total of 1,168 barriers were content-analyzed, yielding nine major themes including fatigue, time constraints, and physical limitations. Exercise self-efficacy predicted LTPA from gestational weeks 18 to 24 (beta = 0.32, R(2) = 0.26) and weeks 30 to 36 (beta = 0.41, R(2) = 0.37), while barrier self-efficacy predicted LTPA from weeks 24 to 30 (beta = 0.40, R(2) = 0.32). Pregnant women face numerous barriers to LTPA during pregnancy, the nature of which may change substantially over the course of pregnancy. Higher levels of self-efficacy to exercise and to overcome exercise barriers are associated with greater LTPA during pregnancy. Research and interventions to understand and promote LTPA during pregnancy should explore the dynamic nature of exercise barriers and foster women's confidence to overcome physical activity barriers.

    The management goal of cerebral palsy (CP) is improving functionality, locomotion and independence. Treatment programs commonly encompass adapted physical activity (APA). This review summarizes the knowledge regarding the effects and recommendations for APA in persons with CP. In addition, barriers to APA in this population are reviewed. The available literature on benefits of APA to persons with CP has focused mainly on youth. The components of the APA programs generally consist of strength, aerobic and flexibility training. There is no empirical evidence that strength-training increases spasticity in people with CP. Furthermore, strength-training may increase strength and the ability to perform daily activities. Aerobic-training is especially important as persons with CP typically have low cardiorespiratory fitness and high prevalence of cardiac disease. However, limited published evidence exists on aerobic-training effects in this population. Nonetheless, the evidence suggests that aerobic-training in persons with CP can improve physiological outcomes, yet the influence of these changes on participation has not been investigated sufficiently. Stretching exercise is a common treatment for spasticity. Surprisingly, there is inconclusive evidence for the effectiveness of stretching exercise for persons with CP. Despite the importance attributed to APA for people with CP, low levels of physical activity have been reported in this population. However, when caregivers perceive greater benefits of exercise, individuals with CP are more likely to be active. In contrast, barriers to APA include costs of APA programs, limited means of transportation to APA facilities, lack of information regarding APA facilities and limited appropriate exercising equipment in the APA facilities.

    Emil Sundstrup

    2014-01-01

    Full Text Available Slaughterhouse work involves a high degree of repetitive and forceful upper limb movements and thus implies an elevated risk of work-related musculoskeletal disorders. High intensity strength training effectively rehabilitates musculoskeletal disorders among sedentary employees, but less is known about the effect among workers with repetitive and forceful work demands. Before performing randomized controlled trials it may be beneficial to assess the cross-sectional connection between exercise and musculoskeletal pain. We investigated the association between high intensity physical exercise and pain among 595 slaughterhouse workers in Denmark, Europe. Using logistic regression analyses, odds ratios for pain and work disability as a function of physical exercise, gender, age, BMI, smoking, and job position were estimated. The prevalence of pain in the neck, shoulder, elbow, and hand/wrist was 48%, 60%, 40%, and 52%, respectively. The odds for experiencing neck pain were significantly lower among slaughterhouse workers performing physical exercise (OR = 0.70, CI: 0.49–0.997, whereas the odds for pain in the shoulders, elbow, or hand/wrist were not associated with exercise. The present study can be used as general reference of pain in the neck and upper extremity among slaughterhouse workers. Future studies should investigate the effect of high intensity physical exercise on neck and upper limb pain in slaughterhouse workers.

    Full Text Available Objectives: This study’s objective was to assess the effects of a 12-month physical exercise intervention on work ability (WAI and cardiorespiratory fitness (CRF in healthy working adults. Methods: The study group had 371 participants, of which 338 (212 women and 126 men were allocated in the exercise group and 33 (17 women and 16 men in the control group. The exercise group underwent a 12-month exercise program followed by a 12-month follow-up. WAI and CRF were evaluated at baseline, and at 4, 8, 12, and 24 study months, in both exercise and control groups. The exercise group was divided into subgroups according to baseline WAI classifications (poor/moderate, good, excellent. Results: During the 12-month exercise intervention, the exercise group increased their leisure-time physical activity by 71% (p = 0.016 and improved the mean WAI by 3% and CRF by 7% (p < 0.0001, in both, while WAI and CRF decreased in the control group (ANCOVA using age, sex and BMI as covariates, for WAI, p = 0.013 and for CRF, p = 0.008. The changes in WAI and CRF between the exercise group and control group were significantly different during the intervention (baseline vs. 12-months, p = 0.028 and p = 0.007 and after the follow-up (p = 0.001 and p = 0.040, respectively. A light positive correlation between the changes in WAI and in CRF (r = 0.19, p < 0.01 existed. WAI improvement was the highest (13%, p < 0.0001 in the subgroup having poor/moderate WAI at baseline (ANCOVA, p < 0.001. Conclusions: The improvement of WAI associated with CRF. These results suggest that a physical exercise intervention may improve work ability.

    Physical exercise improves functional recovery after stroke through a complex mechanism that is not fully understood. Transient focal cerebral ischemia induces autophagy, apoptosis and neurogenesis in the peri-infarct region. This study is aimed to examine the effects of physical exercise on autophagy, apoptosis and neurogenesis in the peri-infarct region in a rat model of transient middle cerebral artery occlusion (MCAO). We found that autophagosomes, as labeled by microtubule-associated protein 1A light chain 3-II (LC3-II), were evident in the peri-infarct region at 3 days after 90-minute MCAO. Moreover, 44.6% of LC3-positive cells were also stained with TUNEL. The number of LC3 positive cells was significantly lower in physical exercise group than in control group at 14 and 21 days after MCAO. Suppression of autophagosomes by physical exercise was positively associated with improvement of neurological function. In addition, physical exercise significantly decreased the number of TUNEL-positive cells and increased the numbers of Ki67-positive, a proliferative marker, and insulin-like growth factor-1 (IGF-1) positive cells at 7, 14, and 21 days after MCAO. The present results demonstrate that physical exercise enhances neurological function possibly by reduction of autophagosome accumulation, attenuation of apoptosis and enhancement of neurogenesis in the peri-infarct region after transient MCAO in rats.

    Pregnancy is a good time to develop healthy lifestyle habits including regular exercise and good nutrition. Programs of physical exercise for pregnant women have been recommended; however, there are few references on this subject in the literature. The objective of this study was to evaluate the knowledge, attitude and practice of pregnant women with respect to appropriate physical exercise during pregnancy, and also to investigate why some women do not exercise during pregnancy. A descriptive study was conducted in which 161 women of 18 to 45 years of age were interviewed in the third trimester of pregnancy. These women were receiving prenatal care at National Health Service (SUS) primary healthcare units and had no pathologies for which physical exercise would constitute a risk. The women were selected at an ultrasonography clinic accredited to the SUS in Campinas, São Paulo. A previously elaborated knowledge, attitude and practice (KAP) questionnaire was used to collect data, which were then stored in an Epinfo database. Statistical analysis was conducted using Pearson's chi-square test and Fisher's exact test to evaluate the association between the study variables (p exercise during pregnancy and the vast majority (93.8%) was in favor of it. Nevertheless, only just over 20% of the women in this sample exercised adequately. Significant associations were found between an adequate knowledge of physical exercise during pregnancy and education level (p = 0.0014) and between the adequate practice of physical exercise during pregnancy and having had fewer pregnancies (p = 0.0001). Lack of time and feeling tired and uncomfortable were the principal reasons given by the women for not exercising. These results suggest that women's knowledge concerning the practice of physical exercise during pregnancy is reasonable and their attitude is favorable; however, relatively few actually exercise during pregnancy.

    Background The magnitude of the negative energy balance induced by exercise may be reduced due to compensatory increases in energy intake. Objective To address the question: Does increased exercise or physical activity alter ad-libitum daily energy intake or macronutrient composition in healthy adults? Data Sources PubMed and Embase were searched (January 1990–January 2013) for studies that presented data on energy and/or macronutrient intake by level of exercise, physical activity or change in response to exercise. Ninety-nine articles (103 studies) were included. Study Eligibility Criteria Primary source articles published in English in peer-reviewed journals. Articles that presented data on energy and/or macronutrient intake by level of exercise or physical activity or changes in energy or macronutrient intake in response to acute exercise or exercise training in healthy (non-athlete) adults (mean age 18–64 years). Study Appraisal and Synthesis Methods Articles were grouped by study design: cross-sectional, acute/short term, non-randomized, and randomized trials. Considerable heterogeneity existed within study groups for several important study parameters, therefore a meta-analysis was considered inappropriate. Results were synthesized and presented by study design. Results No effect of physical activity, exercise or exercise training on energy intake was shown in 59% of cross-sectional studies (n = 17), 69% of acute (n = 40), 50% of short-term (n = 10), 92% of non-randomized (n = 12) and 75% of randomized trials (n = 24). Ninety-four percent of acute, 57% of short-term, 100% of non-randomized and 74% of randomized trials found no effect of exercise on macronutrient intake. Forty-six percent of cross-sectional trials found lower fat intake with increased physical activity. Limitations The literature is limited by the lack of adequately powered trials of sufficient duration, which have prescribed and measured exercise energy expenditure

    This review focuses on the benefits of regular physical activity participation have mainly focused on cognitive functioning, anxiety and depression, and self-concept. It is well documented that ex- ercise can enhance cognitive functioning, improve executive function at old age, and improve mental abil- ity of children labeled as educational subnormal or disability. Regular exercise has been used to reduce stress and ward off anxiety and feelings of depression. In addition, exercise can improve self-esteem and positive outlook in life. Studies in these three main areas were reviewed and issues and future directions were highlighted.

    Background Chronic pain is defined as pain lasting beyond normal tissue healing time, generally taken to be 12 weeks. It contributes to disability, anxiety, depression, sleep disturbances, poor quality of life, and healthcare costs. Chronic pain has a weighted mean prevalence in adults of 20%. For many years, the treatment choice for chronic pain included recommendations for rest and inactivity. However, exercise may have specific benefits in reducing the severity of chronic pain, as well as more general benefits associated with improved overall physical and mental health, and physical functioning. Physical activity and exercise programmes are increasingly being promoted and offered in various healthcare systems, and for a variety of chronic pain conditions. It is therefore important at this stage to establish the efficacy and safety of these programmes, and furthermore to address the critical factors that determine their success or failure. Objectives To provide an overview of Cochrane Reviews of adults with chronic pain to determine (1) the effectiveness of different physical activity and exercise interventions in reducing pain severity and its impact on function, quality of life, and healthcare use; and (2) the evidence for any adverse effects or harm associated with physical activity and exercise interventions. Methods We searched theCochrane Database of Systematic Reviews (CDSR) on the Cochrane Library (CDSR 2016, Issue 1) for systematic reviews of randomised controlled trials (RCTs), after which we tracked any included reviews for updates, and tracked protocols in case of full review publication until an arbitrary cut-off date of 21 March 2016 (CDSR 2016, Issue 3). We assessed the methodological quality of the reviews using the AMSTAR tool, and also planned to analyse data for each painful condition based on quality of the evidence. We extracted data for (1) self-reported pain severity, (2) physical function (objectively or subjectively measured), (3

    To investigate the impact of a multicomponent exercise program on anthropometry, physical function, and physical activity on older adults living in long-term nursing homes (LTNH), we conducted a randomized controlled trial involving 112 participants aged 84.9 ± 6.9 years. Participants were randomly assigned to an intervention (IG) or control group (CG). The IG participated in a 3-month multicomponent exercise intervention focused on strength, balance, stretching exercises, and walking recommendations. Subjects in the CG participated in routine activities. Analyses of outcome parameters were performed in the entire sample and in two subgroups, classified according to participants' physical function score at baseline. The group-by-time interaction, favoring the IG, was significant for the entire sample and for the participants in the low physical function subgroup for the following parameters: waist circumference, 30-s chair-stand, arm-curl, 8-ft timed up-and-go, SPPB score, gait speed, and Berg scale (p < .05). In participants with higher physical function at baseline, significant group-by-time interaction was observed in the SPPB score and Berg scale (p < .05). When differences were analyzed within groups, the IG maintained or improved in all assessed parameters, while participants in the CG showed a marked decline. Our study showed that a multicomponent exercise program is effective for older people living in LTNH. This is especially relevant in those with lower physical function scores. The lower efficacy of the program in participants with better function might be due to the insufficient exercise demands of our intervention for more fit residents. Future studies should analyze the effects of programs with higher intensities in older people with intermediate to high physical function. Copyright © 2018 Elsevier Inc. All rights reserved.

    Full Text Available The purpose of this study was to investigate the effect of continuous exercise and lifestyle-embedded physical activity upon glucose regulation, and assess the feasibility of seven day continuous glucose monitoring (CGM in a normoglycaemic individual. One physically active non-diabetic male [age: 22 y; mass: 71.5 kg; height: 181 cm] underwent 7 days CGM, performing 3 trial conditions: a sedentary control (< 2500 steps, pedometer controlled, a continuous exercise condition (2 x 30 min treadmill running at 70% HRmax, and a lifestyleembedded physical activity condition (100 min fractionalized moderate activity. Diet was standardised andphysical activity levels were monitored via accelerometry throughout. Results showed a significant difference of -0.24 mmol.dL-1 in twenty-four hour mean glucose levels between the sedentary and continuous condition (p = 0.00, and a significant difference of -0.038 mmol.L-1 in twenty-four hour mean glucose levels between thesedentary and lifestyle embedded physical activity condition (p = 0.004.

    Practice tutors' evaluation to (i) establish current physical activity and exercise promotion and prescription curriculum content and (ii) their knowledge, attitudes and beliefs concerning physical activity and exercise prescription in clinical education, in terms of contemporary and emerging health trends and priorities. A cross sectional survey employing a questionnaire and focus groups. All practice tutors delivering physiotherapy undergraduate education in four physiotherapy schools in Ireland (n=38) were invited to participate. Thirty participated giving a response rate of 79%. Two methods of data collection were employed. Clinical content questionnaires were administered, the results of which informed follow-up focus groups. Focus group transcriptions were analysed using the 'Framework Analysis' method. 66% of practice tutors were unhappy with their own knowledge and felt they required further training in the following areas: strategies for changing physical activity behaviour; exercise promotion and prescription for public health; exercise prescription for lifestyle related disease. Main themes emerging from the focus groups were (i) perceptions of the physiotherapist's role, (ii) perceptions of the practice tutor's role and (iii) facilitators and barriers to change. In terms of physical activity and exercise prescription education, practice tutors identified a need for further education to improve their knowledge base. However, their attitudes and beliefs relating to physiotherapists' and educators' role in terms of teaching contemporary and emerging health trends and priorities were mixed. Results of this study provide useful data to inform future physiotherapy curricula development in terms of physical activity and exercise content. Copyright © 2011 Chartered Society of Physiotherapy.

    Late-life depression is often associated with cognitive impairments and disability, which may persist even after adequate antidepressant drug treatment. Physical exercise is increasingly recognized as an effective antidepressant agent, and may exert positive effects on these features too. However, few studies examined this issue, especially by comparing different types of exercises. We performed secondary analyses on data from the Safety and Efficacy of Exercise for Depression in Seniors study, a trial comparing the antidepressant effectiveness of sertraline (S), sertraline plus thrice-weekly non-progressive exercise (S+NPE), and sertraline plus thrice-weekly progressive aerobic exercise (S+PAE). Exercise was conducted in small groups and monitored by heart rate meters. Patients with late-life depression without severe cognitive impairment were recruited from primary care and assessed at baseline and 24 weeks, using the Montreal Cognitive Assessment (MOCA, total and subdomain scores) and Brief Disability Questionnaire. Analyses were based on Generalized Linear Models. In total, 121 patients (mean age 75, 71% females) were randomized to the study interventions. Compared with the S group, patients in the S+PAE group displayed greater improvements of MOCA total scores (p=0.006, effect size=0.37), visuospatial/executive functions (p=0.001, effect size=0.13), and disability (p=0.02, effect size=-0.31). Participants in the S+NPE group did not display significant differences with the control group. Adding aerobic, progressive exercise to antidepressant drug treatment may offer significant advantages over standard treatment for cognitive abilities and disability. These findings suggest that even among older patients exercise may constitute a valid therapeutic measure to improve patients' outcomes.

    Recently there has been increasing interest in the study of ultra-short- term heart rate variability (HRV) in sports performance and exercise physiology. In order to improve standardization of this specific analysis, we evaluated the ultra-short-term HRV analysis through SD1Poincaré index to identify exercise induced responses. We investigated 35 physically active men aged between 18 and 35 years old. Volunteers performed physical exercise on treadmill with intensity of 6.0 km / hour + 1% slope in the first five minutes for physical "warming up." This was followed by 25 minutes with intensity equivalent to 60% of Vmax, with the same slope according to the Conconi threshold. HRV was analyzed in the following periods: the five-minute period before the exercise and the five-minute period immediately after the exercise, the five minutes were divided into five segments of 60 RR intervals. Ultra-short-term RMSSD and SD1 analysis were performed. Ultra-short-term RMSSD and SD1 were significantly (panalysis with the Poincaré plot detected changes in HRV after exercise. Ultra-short-term HRV analysis through Poincaré plot identified heart rate autonomic responses induced by aerobic exercise.

    Full Text Available The study is an attempt to assess the impact of self-evaluation and motivation on physical exercise. In the chapter, material and methods describe the specificity of the research methodology, their purpose being to compare the outcome of subjective evaluation after FMS with the objective outcome of FMS, self-esteem, and motivation analysis for sport, and the hypothesis that Additional activity does not affect the higher self-esteem and it can be assumed that the age range does not affect the result of external motivation. Materials and research tools such as questionnaire, FMS test and SMS scale were also defined. The research was done on a group of 30 people. The group included 14 women and 16 men. More than half of the respondents (53% are between 20 and 22 years of age, 27% are between 23 and 24 years old, and 20% are between 17 and 19 years of age. Analysis of the research revealed that as many as 19 people trained their discipline over 6 years, another 9 had a training period of 2-4 years, while only 2 respondents are beginners. It has also been reported that men in the research group practice up to 7 training units a week more than women. Up to half of the group, 15 people practice their amateur discipline without achieving any sports successes, 9 people are players and 2 and 3 league players, while only 6 are participating in the championship. In turn, 24 out of 30 respondents have additional physical activity. Participants in the study rated their physical fitness very high, 28 out of 30 rated it very good and good, and only 2 rated it sufficiently. The most subjectively assessed element of physical fitness was the strength that 22 people rated very good and good. This can be a testimony to the volleyballs grown by the test subjects - 43%; Other sports 27% (tennis, table tennis, hammering, rowing, basketball, football; Bodybuilding 17% and combat sports 13%. The lowest rated motor ability is flexibility, 20 respondents rated either

    Studies have demonstrated that postnatal women are at high risk for physical inactivity and generally show lower levels of leisure-time physical activity (LTPA) compared to prepregnancy. The overall purpose of the current study was to investigate social cognitive correlates of LTPA among postnatal women during a 6-month period following childbirth. A total of 230 women (mean age = 30.9) provided descriptive data regarding barriers to LTPA and completed measures of LTPA and self-efficacy (exercise and barrier) for at least one of the study data collection periods. A total of 1,520 barriers were content analyzed. Both exercise and barrier self-efficacy were positively associated with subsequent LTPA. Exercise self-efficacy at postnatal week 12 predicted LTPA from postnatal weeks 12 to 18 (β = .40, R (2) = .18) and exercise self-efficacy at postnatal week 24 predicted LTPA during weeks 24-30 (β = .49, R (2) = .30). Barrier self-efficacy at week 18 predicted LTPA from weeks 18 to 24 (β = .33, R (2) = .13). The results of the study identify a number of barriers to LTPA at multiple time points closely following childbirth which may hinder initiation, resumption or maintenance of LTPA. The results also suggest that higher levels of exercise and barrier self-efficacy are prospectively associated with higher levels of LTPA in the early postnatal period. Future interventions should be designed to investigate causal effects of developing participants' exercise and barrier self-efficacy for promoting and maintaining LTPA during the postnatal period.

The purpose of this study was to examine the association between cognitive function at baseline and change in physical performance after exercise intervention in older adults with mild cognitive impairment.Methods: Forty-four older adults diagnosed with mild cognitive impairment based on the Peterson criteria (mean age 74.8 years consented to and completed a 6-month twice weekly exercise intervention. The Timed Up and Go (TUG test was used as a measure of physical performance. The Mini-Mental State Examination (MMSE, Trail Making Test Part B, Geriatric Depression Scale, baseline muscle strength of knee extension, and attendance rate of intervention, were measured as factors for predicting trainability.Results: In the correlation analysis, the change in TUG showed modest correlations with attendance rate in the exercise program (r = -0.354, P = 0.027 and MMSE at baseline (r = -0.321, P = 0.034. A multiple regression analysis revealed that change in TUG was independently associated with attendance rate (ß = -0.322, P = 0.026 and MMSE score (ß = -0.295, P = 0.041, controlling for age and gender.Conclusion: General cognitive function was associated with improvements in physical performance after exercise intervention in

    What are the perceptions of parents of children with physical disabilities about the home exercise programs that physiotherapists prescribe? How do these perceptions affect adherence to home exercise programs? Qualitative study using focus groups and a modified grounded theory approach. Parents of children with physical disabilities who have been prescribed a home exercise program by physiotherapists. Twenty-eight parents participated in the focus groups. Two key themes that related to adherence to home exercise programs in young children with physical disabilities were identified: the characteristics of the home exercise program; and the characteristics of the physiotherapist's teaching style. In the first theme, the participants described their experiences regarding their preference for exercises, which was related to the perceived effects of the exercises, their complexity, and the number of exercises undertaken. These factors determined the amount of time spent performing the exercises, the effect of the exercises on the family's relationships, and any sense of related burden. In the second theme, participants revealed that they adhered better to prescribed exercises when their physiotherapist made an effort to build their confidence in the exercises, helped the parents to incorporate the home exercise program into their daily routine, provided incentives and increased motivation. Parents perceive that their children's adherence to home-based exercises, which are supervised by the parents, is more successful when the physiotherapist's style and the content of the exercise program are positively experienced. These findings reveal which issues should be considered when prescribing home exercise programs to children with physical disabilities.

    Dual-process models of health behavior posit that implicit and explicit attitudes independently drive healthy behaviors. Prior evidence indicates that implicit attitudes may be related to weekly physical activity (PA) levels, but the extent to which self-regulation attenuates this link remains unknown. This study examined the associations between implicit attitudes and self-reported PA during leisure time among 150 highly active young adults and evaluated the extent to which effortful control (one aspect of self-regulation) moderated this relationship. Results indicated that implicit attitudes toward exercise were unrelated to average workout length among individuals with higher effortful control. However, those with lower effortful control and more negative implicit attitudes reported shorter average exercise sessions compared with those with more positive attitudes. Implicit and explicit attitudes were unrelated to total weekly PA. A combination of poorer self-regulation and negative implicit attitudes may leave individuals vulnerable to mental and physical health consequences of low PA.

  14. The Role of Physical Exercise in Inflammatory Bowel Disease

    Full Text Available We reviewed and analyzed the relationship between physical exercise and inflammatory bowel disease (IBD which covers a group of chronic, relapsing, and remitting intestinal disorders including Crohn’s disease (CD and ulcerative colitis. The etiology of IBD likely involves a combination of genetic predisposition and environmental risk factors. Physical training has been suggested to be protective against the onset of IBD, but there are inconsistencies in the findings of the published literature. Hypertrophy of the mesenteric white adipose tissue (mWAT is recognized as a characteristic feature of CD, but its importance for the perpetuation of onset of this intestinal disease is unknown. Adipocytes synthesize proinflammatory and anti-inflammatory cytokines. Hypertrophy of mWAT could play a role as a barrier to the inflammatory process, but recent data suggest that deregulation of adipokine secretion is involved in the pathogenesis of CD. Adipocytokines and macrophage mediators perpetuate the intestinal inflammatory process, leading to mucosal ulcerations along the mesenteric border, a typical feature of CD. Contracting skeletal muscles release biologically active myokines, known to exert the direct anti-inflammatory effects, and inhibit the release of proinflammatory mediators from visceral fat. Further research is required to confirm these observations and establish exercise regimes for IBD patients.

    During ageing, a progressive loss of skeletal muscle mass and a decrease in muscle strength and endurance take place, in the condition termed sarcopenia. The mechanisms of sarcopenia are complex and still unclear; however, it is known that muscle atrophy is associated with a decline in the number and/or efficiency of satellite cells, the main contributors to muscle regeneration. Physical exercise proved beneficial in sarcopenia; however, knowledge of the effect of adapted physical exercise on the myogenic properties of satellite cells in aged muscles is limited. In this study the amount and activation state of satellite cells as well as their proliferation and differentiation potential were assessed in situ by morphology, morphometry and immunocytochemistry at light and transmission electron microscopy on 28-month-old mice submitted to adapted aerobic physical exercise on a treadmill. Sedentary age-matched mice served as controls, and sedentary adult mice were used as a reference for an unperturbed control at an age when the capability of muscle regeneration is still high. The effect of physical exercise in aged muscles was further analysed by comparing the myogenic potential of satellite cells isolated from old running and old sedentary mice using an in vitro system that allows observation of the differentiation process under controlled experimental conditions. The results of this ex vivo and in vitro study demonstrated that adapted physical exercise increases the number and activation of satellite cells as well as their capability to differentiate into structurally and functionally correct myotubes (even though the age-related impairment in myotube formation is not fully reversed): this evidence further supports adapted physical exercise as a powerful, non-pharmacological approach to counteract sarcopenia and the age-related deterioration of satellite cell capabilities even at very advanced age. © 2016 Anatomical Society.

    Full Text Available OBJECTIVE: Physical exercise helps to prevent cardiovascular disorders. Campaigns promoting exercise have taken many people to the parks of our city. The most appropriate exercise for preventing cardiovascular disorders is the aerobic modality; inappropriate exercise acutely increases cardiovascular risk, especially in individuals at higher risk. Therefore, assessing the cardiovascular risk of these individuals and their physical activities is of practical value. METHODS: In the Parque Fernando Costa, we carried out the project "Exercício e Coração" (Exercise and Heart involving 226 individuals. Assessment of the cardiovascular risk and of the physical activity practiced by the individuals exercising at that park was performed with a questionnaire and measurement of the following parameters: blood pressure, weight, height, and waist/hip ratio. The individuals were lectured on the benefits provided by exercise and how to correctly exercise. Each participant received a customized exercise prescription. RESULTS: In regard to risk, 43% of the individuals had health problems and 7% of the healthy individuals had symptoms that could be attributed to heart disorders. High blood pressure was observed in a large amount of the population. In regard to the adequacy of the physical activity, the individuals exercised properly. The project was well accepted, because the participants not only appreciated the initiative, but also reported altering their exercise habits after taking part in the project. CONCLUSION: Data obtained in the current study point to the need to be more careful in assessing the health of individuals who exercise at parks, suggesting that city parks should have a sector designated for assessing and guiding physical activity.

    [Purpose] The purpose of this study was to investigate the effects of aerobic exercise on the resting heart rate, physical fitness, and arterial stiffness or female patients with metabolic syndrome. [Subjects and Methods] Subjects were randomly assigned to an exercise group (n=12) or a control group (n=11). Subjects in the exercise group performed aerobic exercise at 60-80% of maximum heart rate for 40 min 5 times a week for 12 weeks. The changes in metabolic syndrome risk factors, resting heart rate, physical fitness, and arterial stiffness were measured and analyzed before and after initiation of the exercise program to determine the effect of exercise. Arterial stiffness was assessed based on brachial-ankle pulse wave velocity (ba-PWV). [Results] Compared to the control group; The metabolic syndrome risk factors (weight, % body fat, waist circumference, systolic blood pressure, diastolic blood pressure, and HDL-Cholesterol) were significantly improved in the exercise: resting heart rate was significantly decreased; VO2max, muscle strength and muscle endurance were significantly increased; and ba-PWV was significantly decreased. [Conclusion] Aerobic exercise had beneficial effects on the resting heart rate, physical fitness, and arterial stiffness of patients with metabolic syndrome.

    The impact of exercise self-efficacy levels (ESE) on exercise participation, levels of body fat (BF), and bone mineral density (BMD) are unclear in senior-aged adults. The purpose of this study was to investigate effects of ESE on exercise participation, regional distribution of BF, and BMD among seniors. Senior adults (N.=76; 36 males, 40 females) were separated into tertiles (T1, age=60.4±1.4; T2, age=61.3±1.4; T3, age=60.4±1.5) based on self-reported levels of ESE. BMD and regional BF were measured using dual-energy x-ray absorptiometry and exercise participation levels were measured using the Rapid Physical-Activity Questionnaire. MANOVA revealed a significant Wilks Lambda (p exercise participation levels, android BF, gynoid BF, and spinal BMD. ANOVA revealed T3 was significantly lower for android BF (p=0.002) than T1 and T2 (30% and 26%, respectively) while gynoid BF was significantly lower (p=0.012) for T3 (24%) compared to T1. When evaluating exercise participation levels, T3 was significantly higher (p < 0.001) than T1 or T2. Spinal BMD was significantly higher (p=0.030) between T2 (10%) and T1. ESE is an important factor in senior adults ability to maintain longitudinal health.

    Physical exercise improves walking in the elderly but much less is known about its effect on more challenged gait, such as obstacle negotiation. We conducted a systematic review to discuss the effects of regular physical exercise on kinematics and kinetics of obstacle negotiation in the elderly. A comprehensive literature search revealed 859 citations for review, whereof 206 studies entered the full-text analysis. After application of inclusion and exclusion criteria, 13 studies were included in this systematic review. Most of them presented a reasonable quality (average 0.68) but none of them reached the level of a randomized control trial. Interventions were heterogeneous, with training periods lasting from 5 days to 10 months. Studies assessed obstacle negotiation basically considering 3 types of testing paradigm, namely a walkway with either a single obstacle crossing, or with multiple obstacles, or else a treadmill with an obstacle avoidance task under time pressure. In general, longer training programs had better results and very short ones were not effective. A weekly frequency of 2-3 times was the most common among the studies showing positive effects. Regardless of exercises types performed, most of them were effective and so far, there is no consensus about the best exercise for improving obstacle negotiation. A lack of studies on this topic still is evident. Including a record of fall score can further help in deciding which programs are to be preferred. Copyright © 2016 Elsevier Ireland Ltd.

    Menopause related symptoms modify quality of life and may also have an impact on work ability. The aim of this study was to investigate the effects of physical exercise on work ability and daily strain among women with menopausal symptoms. Occupationally active symptomatic menopausal women (n=123) were randomized into 24-week aerobic exercise intervention and control groups. Mobile phone questionnaires were used to collect daily data on perceived physical and mental strain in a randomised and controlled setting. Work ability was measured with the Work Ability Index (WAI) and with questions about work strain. In all 123 women aged 44-62 (mean age 53.8 ± 3.4) years who worked full- or part-time participated in the study. Women were randomized into a control (n=60) and intervention group (n=63). The subjects were mostly working in mentally demanding jobs (e.g., office worker), but also in physical (e.g., cleaner) and mixed (physical and mental) jobs (e.g., nurse). The increase in mental resources and decrease in physical strain from baseline to end were statistically significantly greater among the intervention group than among the control group. Between-group differences in the change in WAI were, however, statistically non-significant. A 6-month physical exercise intervention among symptomatic menopausal women seems not to be enough to increase perceived work ability but the physical exercise may increase perceived mental resources and decrease perceived daily physical strain.}

    Regular physical exercise has been reported to reduce depressive symptoms. Several lines of evidence suggest that physical exercise may prevent depression by promoting social support or resilience, which is the ability to adapt to challenging life conditions. The aim of this study was to compare depressive symptoms, social support, and resilience between Japanese company workers who engaged in regular physical exercise and workers who did not exercise regularly. We also investigated whether regular physical exercise has an indirect association with depressive symptoms through social support and resilience. Participants were 715 Japanese employees at six worksites. Depressive symptoms were assessed with the Center for Epidemiologic Studies Depression (CES-D) scale, social support with the short version of the Social Support Questionnaire (SSQ), and resilience with the 14-item Resilience Scale (RS-14). A self-report questionnaire, which was extracted from the Japanese version of the Health-Promoting Lifestyle Profile, was used to assess whether participants engage in regular physical exercise, defined as more than 20 min, three or more times per week. The group differences in CES-D, SSQ, and RS-14 scores were investigated by using analysis of covariance (ANCOVA). Mediation analysis was conducted by using Preacher and Hayes' bootstrap script to assess whether regular physical exercise is associated with depressive symptoms indirectly through resilience and social support. The SSQ Number score (F = 4.82, p = 0.03), SSQ Satisfaction score (F = 6.68, p = 0.01), and RS-14 score (F = 6.01, p = 0.01) were significantly higher in the group with regular physical exercise (n = 83) than in the group without regular physical exercise (n = 632) after adjusting for age, education, marital status, and job status. The difference in CES-D score was not significant (F = 2.90, p = 0.09). Bootstrapping revealed significant negative indirect

    The purpose of this study was to determine the acute and residual impact of a single exercise bout on meal glucose control in adolescents with habitually low physical activity. Twelve adolescents (seven females/five males, 14 ± 2 yr) completed three trials. One trial [No Exercise (No Ex)] was completed after refraining from vigorous activity for ≥ 3 d. On the other two trials, a 45-min aerobic exercise bout at 75% peak heart rate was performed either 17-h Prior Day Exercise (Prior Day Ex) trial or 1-h Same Day Exercise (Same Day Ex) trial before consuming the test meal (2803 kJ, 45/40/15% energy as carbohydrate/fat/protein, respectively). Compared to No Ex, insulin sensitivity (SI) (minimal model analysis) was increased by 45% (p exercise in adolescents with habitually low physical activity and that the residual beneficial effect of exercise lasts at least 17 h. This finding highlights the plasticity of exercise responses in youth and the importance of daily exercise for metabolic health. © 2012 John Wiley & Sons A/S.

    Chronic pain is defined as pain lasting beyond normal tissue healing time, generally taken to be 12 weeks. It contributes to disability, anxiety, depression, sleep disturbances, poor quality of life, and healthcare costs. Chronic pain has a weighted mean prevalence in adults of 20%.For many years, the treatment choice for chronic pain included recommendations for rest and inactivity. However, exercise may have specific benefits in reducing the severity of chronic pain, as well as more general benefits associated with improved overall physical and mental health, and physical functioning.Physical activity and exercise programmes are increasingly being promoted and offered in various healthcare systems, and for a variety of chronic pain conditions. It is therefore important at this stage to establish the efficacy and safety of these programmes, and furthermore to address the critical factors that determine their success or failure. To provide an overview of Cochrane Reviews of adults with chronic pain to determine (1) the effectiveness of different physical activity and exercise interventions in reducing pain severity and its impact on function, quality of life, and healthcare use; and (2) the evidence for any adverse effects or harm associated with physical activity and exercise interventions. We searched theCochrane Database of Systematic Reviews (CDSR) on the Cochrane Library (CDSR 2016, Issue 1) for systematic reviews of randomised controlled trials (RCTs), after which we tracked any included reviews for updates, and tracked protocols in case of full review publication until an arbitrary cut-off date of 21 March 2016 (CDSR 2016, Issue 3). We assessed the methodological quality of the reviews using the AMSTAR tool, and also planned to analyse data for each painful condition based on quality of the evidence.We extracted data for (1) self-reported pain severity, (2) physical function (objectively or subjectively measured), (3) psychological function, (4) quality of

Cross-sectional, observational study. Community-dwelling, elderly individuals. One hundred and fifty-four elderly individuals were categorised into four groups according to their smoking status: never smokers (n=57), passive smokers (n=30), ex-smokers (n=45) and current smokers (n=22). Exercise capacity [6-minute walk test (6MWT)], physical activity in daily life (step counting) and health-related quality of life [36-Item Short Form Health Survey (SF-36) questionnaire] were assessed. Current and ex-smokers had lower mean exercise capacity compared with never smokers: 90 [standard deviation (SD) 10] % predicted, 91 (SD 12) % predicted and 100 (SD 13) % predicted distance on 6MWT, respectively [mean differences -9.8%, 95% confidence intervals (CI) -17.8 to -1.8 and -9.1%, 95% CI -15.4 to -2.7, respectively; Pexercise capacity than never smokers. Although the level of physical activity did not differ between the groups, an association was found with smoking.

    Evaluation of designed and implemented physical protection system (PPS) is essential for ensuring the effectiveness of PPS. In Japan, nuclear facility operators, which are required to assess performance of PPS, have conducted performance test of PPS element and periodical trainings as well as annual PPS exercise with relevant agencies. In addition to these practical or field efforts, non-field tool for evaluating PPS effectiveness such as tabletop exercise (TTX) can be utilized as it is applied in the USA and other countries. This paper discusses the potential advantage of TTX as an evaluation tool of PPS effectiveness, looking at the characterizations of TTX in comparison to field evaluations, and potential cases where operator would get benefit from TTX especially.

    Polycystic ovary syndrome (PCOS) affects 12-21% of women in the childbearing age and is the most common cause of hyperandrogenaemia and anovulatory infertility. There is an increase in insulin resistance in both overweight and lean women with PCOS. Exercise treatment is mandatory among the overweight women due to sufficient evidence that it can improve the signs and symptoms of PCOS. This has not been fully investigated among the lean. However, new randomized controlled trials show that structured physical exercise can also improve insulin sensitivity, hyperandrogenaemia and menstrual frequency in lean women with PCOS.

    The prevalence and consequences of musculoskeletal pain is considerable among healthcare workers, allegedly due to high physical work demands of healthcare work. Previous investigations have shown promising results of physical exercise for relieving pain among different occupational groups, but the question remains whether such physical exercise should be performed at the workplace or conducted as home-based exercise. Performing physical exercise at the workplace together with colleagues may be more motivating for some employees and thus increase adherence. On the other hand, physical exercise performed during working hours at the workplace may be costly for the employers in terms of time spend. Thus, it seems relevant to compare the efficacy of workplace- versus home-based training on musculoskeletal pain. This study is intended to investigate the effect of workplace-based versus home-based physical exercise on musculoskeletal pain among healthcare workers. This study was designed as a cluster randomized controlled trial performed at 3 hospitals in Copenhagen, Denmark. Clusters are hospital departments and hospital units. Cluster randomization was chosen to increase adherence and avoid contamination between interventions. Two hundred healthcare workers from 18 departments located at three different hospitals is allocated to 10 weeks of 1) workplace based physical exercise performed during working hours (using kettlebells, elastic bands and exercise balls) for 5 × 10 minutes per week and up to 5 group-based coaching sessions, or 2) home based physical exercise performed during leisure time (using elastic bands and body weight exercises) for 5 × 10 minutes per week. Both intervention groups will also receive ergonomic instructions on patient handling and use of lifting aides etc. Inclusion criteria are female healthcare workers working at a hospital. Average pain intensity (VAS scale 0-10) of the back, neck and shoulder (primary outcome) and physical

Future interventions (including exercise training) focusing on increasing physical activity levels may have important clinical impacts on both OSA severity and the burden of associated co-morbidities. Objective measurement of physical activity in routine OSA management and well-designed clinical trials are recommended. Registration # CRD42017057319 (Prospero).

    The aim of this manuscript was to review the knowledge about leptin, detailing its relationship with energetic intake and physical activity. Leptin is an adipocyte hormone, recognized mainly for its putative role in control of energy expenditure, food intake, body weight and reproductive function. Leptin has still important peripheral actions, including its role on the ovarian tissue. The intracellular signaling mechanisms are recognized in hypothalamus, but in peripheral tissue are not fully understood. The exercise, when practiced by women, if not appropriately planned according to food intake, can modify the leptin release. When energy imbalances induced by exercise and/or deficient food ingestion occurs, low leptin levels are observed, leading to a reduction in GnRH (gonadotropin-release hormone), in LH (luteinizing hormone) and FSH (follicle-stimulating hormone) in pituitary, and consequently a minor release of ovarian estrogens. This process is named hypothalamic amenorrhea, and has repercussions in the woman's health. In this perspective, it is important to emphasize the need to evaluate the energy expenditure from exercise and to formulate adequate alimentary plans to these individuals.

    We examined the possible mediating role of physical self-perceptions, physical self-esteem, and global self-esteem in the relationships between exercise and depression in a group of socioeconomically disadvantaged women with elevated symptoms of depression. Forty-four female residents of a low-income housing complex were randomized into a 7-week-long exercise-training group or a wait-list group. Depression, physical self-perceptions and self-esteem were measured repeatedly. Significant changes were found for depression, self-esteem, physical self-worth, and self-perceived physical condition in the exercise-training group. Intent-to-treat analyses did not alter the results. Most of the reduction in depression occurred between Week 2 and Week 4 while initial improvement in physical self-worth and self-perceived physical condition was observed between baseline and Week 2. These variables can be seen as plausible mechanisms for effects of exercise on depression.

    Full Text Available Introduction. Understanding how exercise affects individuals with varying levels of functional ability will provide further insight into the role of exercise during the aging process. It will also aid in the development of exercise programs that are appropriate for a wider spectrum of older adults. Specifically it was the primary aim of this study to determine and compare the effects of 10 weeks of community-based exercise on the cardiovascular endurance, muscular strength, flexibility, and balance fitness components of older adult women with high and moderate-low levels of physical function. Methods. Participants were placed in either the high functioning (n=13 or moderate/low functioning (n=17 groups based on their level of physical functioning. Fitness components were measured by the Senior Fitness Test and physical function was determined by the Composite Physical Function scale. Results. The results of the 3 × 2 mixed ANOVA statistical analysis showed no significant interaction effect for time ⁎ group for any of the six subtests (chair stand, arm curls, 2-minute step, chair sit-and-reach, back scratch, and 6-foot up-and-go of the SFT. However, the main effect of time was significant for all fitness components and the main effect of group was significant for all fitness components except lower extremity flexibility. Discussion. Community-based exercise programs offering a variety of exercise types to people with varying levels of functional ability can be useful in maintaining or improving fitness and independence. These programs may also be capable of improving the self-efficacy of lower functioning older adults toward performing daily tasks.

    Full Text Available Background: Studies have demonstrated the diagnostic accuracy and prognostic value of physical stress echocardiography in coronary artery disease. However, the prediction of mortality and major cardiac events in patients with exercise test positive for myocardial ischemia is limited. Objective: To evaluate the effectiveness of physical stress echocardiography in the prediction of mortality and major cardiac events in patients with exercise test positive for myocardial ischemia. Methods: This is a retrospective cohort in which 866 consecutive patients with exercise test positive for myocardial ischemia, and who underwent physical stress echocardiography were studied. Patients were divided into two groups: with physical stress echocardiography negative (G1 or positive (G2 for myocardial ischemia. The endpoints analyzed were all-cause mortality and major cardiac events, defined as cardiac death and non-fatal acute myocardial infarction. Results: G2 comprised 205 patients (23.7%. During the mean 85.6 ± 15.0-month follow-up, there were 26 deaths, of which six were cardiac deaths, and 25 non-fatal myocardial infarction cases. The independent predictors of mortality were: age, diabetes mellitus, and positive physical stress echocardiography (hazard ratio: 2.69; 95% confidence interval: 1.20 - 6.01; p = 0.016. The independent predictors of major cardiac events were: age, previous coronary artery disease, positive physical stress echocardiography (hazard ratio: 2.75; 95% confidence interval: 1.15 - 6.53; p = 0.022 and absence of a 10% increase in ejection fraction. All-cause mortality and the incidence of major cardiac events were significantly higher in G2 (p < 0. 001 and p = 0.001, respectively. Conclusion: Physical stress echocardiography provides additional prognostic information in patients with exercise test positive for myocardial ischemia.

    Full Text Available Obesity associated with a sedentary lifestyle can lead to changes in the immune system balance resulting in the development of inflammatory diseases. The aim of this study was to compare lymphocyte activation mechanisms between overweight children practicing regular circus physical exercises with non-exercised children. The study comprised 60 pubescent children randomly divided into 4 groups: Overweight Children (OWC (10.67 ± 0.22 years old, Overweight Exercised Children (OWE (10.00 ± 0.41 years old, Eutrophic Children (EC (11.00 ± 0.29 years old and Eutrophic Exercised Children (EE (10.60 ± 0.29 years old. OWE and EE groups practiced circus activities twice a week, for 4.3 ± 0.5 and 4.4 ± 0.5 months, respectively. Percentage of T regulatory cells (Treg and the expression of CD95 and CD25 in CD4+ lymphocytes were evaluated by flow cytometry. Lymphocyte proliferation capacity was measured by [14C]-thymidine incorporation and mRNA expression of IL-35, TGF-beta, IL-2 and IL-10 by real-time PCR. Lymphocyte proliferation was higher in OWC and OWE groups compared with the EC (3509 ± 887; 2694 ± 560, and 1768 ± 208 cpm, respectively and EE (2313 ± 111 cpm groups. CD95 expression on lymphocytes was augmented in the EC (953.9 ± 101.2 and EE groups (736.7 ± 194.6 compared with the OWC (522.1 ± 125.2 and OWE groups (551.6 ± 144.5. CTLA-4 expression was also lower in the OWC and OWE groups compared with the EC and EE groups. Percentage of Treg, IL-35, and IL-10 mRNA expression were lower in the OWC and OWE groups compared with the EC and EE groups. In conclusion, overweight children present altered immune system balance characterized by elevated lymphocyte proliferation due to a decrease in T regulatory cell percentage. These effects were partially reverted by moderate physical exercise, as demonstrated by decreased lymphocyte proliferation.

    Acute physical activity has been repeatedly shown to improve various cognitive functions. However, there have been no investigations comparing the effects of exercise during verbal encoding versus exercise prior to encoding on long-term memory performance. In this current psychoneuroendocrinological study we aim to test whether light to moderate ergometric bicycling during vocabulary encoding enhances subsequent recall compared to encoding during physical rest and encoding after being physically active. Furthermore, we examined the kinetics of brain-derived neurotrophic factor (BDNF) in serum which has been previously shown to correlate with learning performance. We also controlled for the BDNF val66met polymorphism. We found better vocabulary test performance for subjects that were physically active during the encoding phase compared to sedentary subjects. Post-hoc tests revealed that this effect was particularly present in initially low performers. BDNF in serum and BDNF genotype failed to account for the current result. Our data indicates that light to moderate simultaneous physical activity during encoding, but not prior to encoding, is beneficial for subsequent recall of new items.

    Exercising outdoors provide beneficial effect on mental and physical health for all ages. However, few older people exercise outdoors other than walking. While outdoor gyms have become increasingly common in Australia, limited outdoor exercise equipment specifically designed for older people is available in public spaces. We have set up and evaluated a unique purpose-built outdoor exercise park for older people in the community setting and demonstrated positive physical and well-being outcomes associated with the provision of this unique exercise mode and social programme. This study is a reflective narrative describing this innovative exercise approach and reports challenges associated with establishment of the exercise park, conducting the randomised trial, strategies adopted to address these challenges and recommendations for future implementation of this approach in the community. Many challenges were encountered, including securing appropriate land to locate the exercise park, control of environmental factors for safety (non-slippery ground and equipment) as well as logistics in running the exercise programme itself. Several adjustments in the equipment were also required to ensure safe use by older people. The inclusion of outdoor equipment for older people in public spaces or urban parks is important and careful consideration needs to be taken by local/public authorities to provide access, amenities and safety for all as well as activities to suit all ages. SO WHAT?: Seniors' exercise parks can be installed in public places and may provide an enjoyable and effective approach to engage older individuals in a more active and healthier lifestyle. © 2018 The Authors.

    Pilates exercises have several demonstrated physical and psychological benefits. To date, most research in this context was conducted with symptomatic or elderly people with few dependent measures. The current study examined the chronic or longitudinal effects of very low frequency, once a week, Pilates training on several physical and psychological measures, over a 10-week intervention, in young, healthy, and sedentary women. Further, the study gauged the acute effects of Pilates exercises on positive- and negative affect in 10 exercise sessions. Compared to a control group, the Pilates group exhibited significant improvements in skeletal muscle mass, flexibility, balance, core- and abdominal muscle strength, body awareness, and negative affect. This group also showed favorable changes in positive (22.5% increase) and negative affect (12.2% decrease) in nine out of ten exercise sessions. This work clearly demonstrates the acute and chronic benefits of Pilates training on both physical and psychological measures. It also reveals that even only once a week Pilates training is enough to trigger detectable benefits in young sedentary women. While this frequency is below the required levels of exercise for health, it may overcome the 'lack of time' excuse for not exercising and subsequently its tangible benefits may positively influence one's engagement in more physical activity.

    Exercise promotes several health benefits, such as cardiovascular, musculoskeletal and cardiorespiratory improvements. It is believed that the practice of exercise in individuals with psychiatric disorders, e.g. schizophrenia, can cause significant changes. Schizophrenic patients have problematic lifestyle habits compared with general population; this may cause a high mortality rate, mainly caused by cardiovascular and metabolic diseases. Thus, the aim of this study is to investigate changes in physical and mental health, cognitive and brain functioning due to the practice of exercise in patients with schizophrenia. Although still little is known about the benefits of exercise on mental health, cognitive and brain functioning of schizophrenic patients, exercise training has been shown to be a beneficial intervention in the control and reduction of disease severity. Type of training, form of execution, duration and intensity need to be better studied as the effects on physical and mental health, cognition and brain activity depend exclusively of interconnected factors, such as the combination of exercise and medication. However, one should understand that exercise is not only an effective nondrug alternative, but also acts as a supporting linking up interventions to promote improvements in process performance optimization. In general, the positive effects on mental health, cognition and brain activity as a result of an exercise program are quite evident. Few studies have been published correlating effects of exercise in patients with schizophrenia, but there is increasing evidence that positive and negative symptoms can be improved. Therefore, it is important that further studies be undertaken to expand the knowledge of physical exercise on mental health in people with schizophrenia, as well as its dose-response and the most effective type of exercise.

    Full Text Available The present study aimed to investigate the impact of a 6-month multicomponent exercise program (MCEP on physical function, cognition, and hemodynamic parameters of elderly normotensive (NTS and hypertensive (HTS osteoarthritis patients. A total of 99 elderly osteoarthritis patients (44 NTS and 55 HTS were recruited and submitted to functional, cognitive, and hemodynamic evaluations before and after six months of a MCEP. The program of exercise was performed twice a week at moderate intensity. The physical exercises aggregated functional and walking exercises. Results indicate that 6 months of MCEP were able to improve one-leg stand and mobility (walking speeds of osteoarthritis patients regardless of hypertension. On the other hand, cognitive and hemodynamic parameters were not altered after the MCEP. The findings of the present study demonstrate that 6 months of MCEP were able to improve the physical functioning (i.e., usual and maximal walking speed and balance of osteoarthritis patients regardless of hypertensive condition.

    Regular physical activity and exercise (PA&E) reduces cognitive aging, may delay dementia onset, and for persons with dementia, may slow progression and improve quality of life. Memory clinic patients and caregivers described their PA&E and completed the Older Persons' Attitudes Toward Physical Activity and Exercise Questionnaire (OPAPAEQ). Caregivers and patients differed in their PA&E attitudes: patients were less likely to believe in the importance of PA&E for health promotion. PA&E attitudes were explored as predictors of self-reported exercise habits. Belief in the importance of high intensity exercise for health maintenance was the only variable that significantly predicted engagement in regular PA&E. Moreover, caregivers' attitudes toward high intensity exercise predicted memory patients' participation in PA&E. These findings may aid in development of exercise interventions for people with memory problems, and suggest that modification of specific attitudes toward exercise is an important component to ensure maximum participation and engagement in PA&E.

    Full Text Available Osteoarthritis (OA is the most common form of arthritis and a leading cause of disability in older adults. Conservative non-pharmacological strategies, particularly exercise, are recommended by clinical guidelines for its management. The aim of this study was to assess the effectiveness of acupressure versus isometric exercise on pain, stiffness, and physical function in knee OA female patients. This quasi experimental study was conducted at the inpatient and outpatient sections at Al-kasr Al-Aini hospital, Cairo University. It involved three groups of 30 patients each: isometric exercise, acupressure, and control. Data were collected by an interview form and the Western Ontario and McMaster Universities Osteoarthritis index (WOMAC scale. The study revealed high initial scores of pain, stiffness, and impaired physical functioning. After the intervention, pain decreased in the two intervention groups compared to the control group (p < 0.001, while the scores of stiffness and impaired physical function were significantly lower in the isometric group (p < 0.001 compared to the other two groups. The decrease in the total WOMAC score was sharper in the two study groups compared to the control group. In multiple linear regression, the duration of illness was a positive predictor of WOMAC score, whereas the intervention is associated with a reduction in the score. In conclusion, isometric exercise and acupressure provide an improvement of pain, stiffness, and physical function in patients with knee OA. Since isometric exercise leads to more improvement of stiffness and physical function, while acupressure acts better on pain, a combination of both is recommended. The findings need further confirmation through a randomized clinical trial.

  8. Lack of adequate appreciation of physical exercise's complexities can pre-empt appropriate design and interpretation in scientific discovery

    Booth, F W; Laye, M J

    2009-01-01

    Two major issues are presented. First, a challenge is made by us that a misunderstanding of physiology has led to incomplete or wrong functional designations of genes in some cases. Normal physiological processes are dynamic, integrated and periodic, and, therefore, it is difficult to define normal physiological function by looking at a single time point or single process in a non-stressed subject. The ability of the organism to successfully respond to homeostatic disruptions defines normal physiology. Genes were selected for survival and to appropriately respond to stresses, such as physical activity. Omitting gene functions by restricting them to non-stressful conditions could lead to less than optimal primary preventions, treatments and cures for diseases. Physical exercise, as a stressor, should be used to better demonstrate the complete functional classifications of some genes. Second, the challenge from others of an ‘exercise pill’ as a mimetic of natural physical activity will be shown to be lacking a scientific basis. The concept of an ‘exercise pill’/‘exercise mimetic’ demonstrates an inadequate appreciation of the complexities in integrating cell, tissue, organ and systems during both acute disruptions in homeostasis by a single bout of exercise, and longer-term chronic adaptations to different types of exercise such as resistance and endurance. It is our opinion that those promoting drugs targeting a single or few molecules should not redefine the term ‘exercise’ and exercise concepts in an attempt to sensationalize findings. Additionally, the scientific criteria that the authors demand to be met to legitimately use the terms ‘exercise pill’ and ‘exercise mimetic’ are presented. PMID:19723782

    It is known from previous research that physical exercise prevents long-term memory deficits induced by maternal deprivation in rats. But we could not assume similar effects of physical exercise on short-term memory, as short- and long-term memories are known to result from some different memory consolidation processes. Here we demonstrated that, in addition to long-term memory deficit, the short-term memory deficit resultant from maternal deprivation in object recognition and aversive memory tasks is also prevented by physical exercise. Additionally, one of the mechanisms by which the physical exercise influences the memory processes involves its effects attenuating the oxidative damage in the maternal deprived rats' hippocampus and prefrontal cortex.

Before and after the intervention, cognitive outcomes were assessed using the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-cog, Mini-Mental State Examination, and the Clock Drawing Test. Physical performance was evaluated by exercise time, the number of pedal rotation, total load, grip strength, and the Berg Balance Scale (BBS. Results: In all cognitive measures, there were no significant improvements between the two groups after 6 months in the baseline value-adjusted primary analysis. However, the ADAS-cog score was significantly lower between the two groups in secondary analysis adjusted for baseline value, age, sex, and education years. All physical outcomes were significantly higher in the intervention group except for total load compared with baseline measurements. Conclusion: This study indicates that it is possible to improve cognitive function in older adults with moderate to severe AD through 6-month physical exercise with a multicomponent cognitive intervention.

    Social networks influence the spread of depression, health behaviors, and obesity. The social networks of older urban-dwelling adults were examined to assess whether physical inactivity mediated the association between social networks and obesity. Data come from the Montreal Neighborhood Networks and Healthy Aging study (n=2707). Self-reported height and weight were used to calculate body mass index (BMI) with obesity defined as a BMI ≥ 30. A name generator/interpreter instrument was used to elicit participants' core ties (i.e., alters), and assess whether alters exercised regularly and resided in participants' neighborhoods. The International Physical Activity Questionnaire was used to measure physical inactivity. Separate multilevel logistic regression analyses were conducted for younger (18-54 years) and older (55 years plus) age groups to examine the association between the exercising behavior of alters and obesity. Ancillary analyses examined whether the residential location of alters was associated with obesity. Mediation analyses assessed whether physical inactivity mediated the association between alter exercising behavior and obesity. Models adjusted for participant socio-demographic and -economic characteristics. Among the older age stratum (55 years plus), physically inactive individuals were more likely obese (OR 2.14; 95% CIs: 1.48-3.10); participants who had more exercising alters were less likely obese (OR: 0.85; 95% CIs: 0.72-0.99). Physical inactivity mediated the association between exercising alters and obesity. Ancillary analyses showed that having exercising alters in the neighborhood compared to other locations tended to reduce the odds of obesity. This work demonstrates the importance of social networks among older adults in facilitating a physically active lifestyle and reducing the odds of obesity. Such findings can inform the design of public health interventions that seek to improve the environmental conditions supporting the physical

    Full Text Available This research aimed to analyze the validity of the relations hypothesized by the theory of self-determination in predicting adherence to physical exercise in fitness academy users and subjects following personal training. A total of 588 persons from Pelotas / RS / Brazil (405 gym users and 183 subjects following personal training completed the Portuguese version of the three questionnaires, i.e. the Perceived Autonomy Support Climate Exercise Questionnaire, Basic Psychological Needs in the Exercise Scale and Behavioral Regulation in the Exercise Questionnaire −2. The results support the factorial structure of the questionnaires used in this sample. There was a significant multivariate effect of context on self-determination for physical exercise training [Wilks’ λ = 0.934, F (10, 576.000 = 4.03, p < 0.001, η2 = 0.01]. The hypothesized structural equation model, which considered the self-determination theory, showed a good fit to the data (S-B χ2 = 234.703; p= .001; df = 52; χ2/df = 4.514; SRMS = .049; NNFI = .906; CFI = .926; RMSEA = .077; RMSEA 90% CI = .067 − .088. However, in the comparative analysis, the perception of autonomy support, relatedness and competence were significantly higher in the context of personal training, while the amotivation and external regulation were significantly higher in the context of fitness academies.

    Full Text Available Body image self-perception in obese children is important since it can encourage behaviors leading to social isolation and cause an increase in food intake. The objective of this study was to determine the changes produced in the level of body image satisfaction and the variation in anthropometric indicators of young children in the State of Sonora, Mexico after participating in a program of 40 sessions of physical exercise with an average caloric expenditure of 267 Kcal per session. 119 children were enrolled in the program; they were between the ages of 8 and 11 with a body mass index (BMI of 26.59 ± 4.2 (kg/m2. They were evaluated before and after the physical activity intervention by means of a Body Image Satisfaction (BIS Test. The results with significant changes (p ≤ 0.05 between the pre-test and post-test are in weight and height. There are also significant changes observed in self-image in 15 parts of evaluated body segments, mainly in the abdomen, chest, thighs, buttocks, waist, and hips in all children from the experimental group. The results conclude that physical exercise, in spite of not producing significant changes in BMI, can positively modify body image perception.

  17. Dialysis Exercise Team: The Way to Sustain Exercise Programs in Hemodialysis Patients

    Full Text Available Patients affected by end-stage renal disease (ESRD show quite lower physical activity and exercise capacity when compared to healthy individuals. In addition, a sedentary lifestyle is favoured by lack of a specific counseling on exercise implementation in the nephrology care setting. Increasing physical activity level should represent a goal for every dialysis patient care management. Three crucial elements of clinical care may contribute to sustain a hemodialysis exercise program: a involvement of exercise professionals, b real commitment of nephrologists and dialysis professionals, c individual patient adaptation of the exercise program. Dialysis staff have a crucial role to encourage and assist patients during intra-dialysis exercise, but other professionals should be included in the ideal “exercise team” for dialysis patients. Evaluation of general condition, comorbidities (especially cardiovascular, nutritional status and physical exercise capacity are mandatory to propose an exercise program, in either extra-dialysis or intra-dialysis setting. To this aim, nephrologist should lead a team of specialists and professionals including cardiologist, physiotherapist, exercise physiologist, renal dietician and nurse. In this scenario, dialysis nurses play a pivotal role since they guarantee a constant and direct approach. Unfortunately dialysis staff may often lack of information and formation about exercise management while they take care patients during the dialysis session. Building an effective exercise team, promoting the culture of exercise and increasing physical activity levels lead to a more complete and modern clinical care management of ESRD patients.

    Background Physical exercise influences homocysteine (Hcy) concentrations, cognitive function and the metabolic profile. The purpose of this study was to investigate the influence of regular physical exercise on Hcy levels, the metabolic profile and cognitive function in healthy elderly males before and after an endurance exercise program. Methods Forty-five healthy and sedentary volunteers were randomized into 2 groups: (1) a control group asked not to change their normal everyday activities and not to start any regular physical exercise program and (2) an experimental group trained at a heart rate intensity corresponding to ventilatory threshold 1 (VT-1) for 60 min/day 3 times weekly on alternate days for 6 months using a cycle ergometer. All volunteers underwent cognitive evaluations, blood sample analyses and ergospirometric assessments. Results A significant improvement in cognitive function was observed in the experimental group compared with the control group (p 0.05), but there was a significant increase in peak oxygen consumption and workload at VT-1 as well as a significant improvement in cholesterol, triglycerides, HDL, glucose, alkaline phosphatase, urea, T3, T4 and prostate-specific antigen compared with the control group (p < 0.05). Conclusion The data suggest that a physical exercise program does not reduce Hcy levels in healthy elderly males, although it improves the cardiovascular and metabolic profile as well as cognitive function.

    Physical activity (PA) is ranked as a leading health indicator and the workplace is a key setting to promote PA. The purpose of this study was to examine how goal-setting and exercise self-efficacy (SE) during a health promotion program influenced PA level among Japanese workers. Using a cross-sectional study design, we surveyed 281 employees. The short version of the International Physical Activity Questionnaire was used to assess PA level. Exercise SE was assessed using a partially modified version of Oka's exercise SE scale. Personal goals were assessed as the total numbers of "yes" responses to five items regarding "details of personal goals to perform PA". A mediational model was used to examine whether exercise SE mediates between the number of personal goals and PA level. The mean age of the participants was 46.3 years, 76.2% were men, and the most common occupational category was software engineer (30.6%). The average PA level per week exceeded the recommended level in 127 participants (45.2%). One hundred and eighty-four participants (65.5%) set some form of concrete personal goal to perform PA. The relationship between the number of personal goals and PA level was mediated by exercise SE. Our study showed that exercise SE mediates goal-setting and increases PA. The results suggest that the components of PA promotion programs should be tailored to enhance participants' confidence in performing PA.

    In our review we examine the relationship between physical activity and mental health; especially we determine the effectiveness of exercise in the prevention and treatment of depression. Over the past two decades the literature in the area of physical activity and mental health has been growing. However it seems that the findings and evidences not being utilized by mental health agencies and health practitioners. Depression is the most common disorder in the world, generally has a higher prevalence among women. In our study we overview and demonstrate that the exercise is a powerful intervention for prevention and treatment not only in non-clinical but also in clinical levels of depression. In sub-clinical levels of depression the meta-analytic findings and population surveys suggest that the exercise is associated with a significant moderate reduction of depression in different groups by gender and age; as well as a physically active lifestyle associates with lower levels of depression. In clinical levels of depression the physical activity is an effective tool in the prevention, studies support an association between higher levels of physical activity and lower levels of depression. In the treatment of clinical depression the randomized-controlled trials suggest the clear positive effects of exercise. This effect is similar to psychotherapeutic interventions and it was appeared under relatively short time (4-8 weeks). The exercise is one of the most important preventive health-related behaviors. Our review suggests a protective effect from activity on the development of clinical levels of depression and depressive symptoms. In addition the randomized controlled trials support a causal connection between exercise and reduction of depression. In sum the reviewed studies clearly support the antidepressant effect of exercise.

    Numerous studies have reported the prevention of falls through exercise among cognitively healthy older people. This study aimed to determine whether the current evidence supports that physical exercise is also efficacious in preventing falls in older adults with cognitive impairment. Two independent reviewers searched MEDLINE; EMBASE; PsycINFO; the Cumulative Index to Nursing & Allied Health Literature; the Cochrane Central Register of Controlled Trials; the Cochrane Bone, Joint, and Muscle Trauma Group Specialized Register; ClinicalTrials.gov; and the UK Clinical Research Network Study Portfolio up to July 2013 without language restriction. We included randomized controlled trials that examined the efficacy of physical exercise in older adults with cognitive impairment. The methodological qualities of the included trials were appraised according to the criteria developed for the Cochrane review of fall prevention trials. The primary outcome measure was the rate ratio of falls. A meta-analysis was performed to estimate the pooled rate ratio and summarize the results of the trials on fall prevention through physical exercise. Seven randomized controlled trials involving 781 participants were included, 4 of which examined solely older people with cognitive impairment. Subgroup data on persons with cognitive impairment were obtained from the other 3 trials that targeted older populations in general. The meta-analysis showed that physical exercise had a significant effect in preventing falls in older adults with cognitive impairment, with a pooled estimate of rate ratio of 0.68 (95% confidence interval 0.51-0.91). The present analysis suggests that physical exercise has a positive effect on preventing falls in older adults with cognitive impairment. Further studies will be required to determine the modality and frequency of exercise that are optimal for the prevention of falls in this population.

    Full Text Available Abstract Background Regular physical exercise has been reported to reduce depressive symptoms. Several lines of evidence suggest that physical exercise may prevent depression by promoting social support or resilience, which is the ability to adapt to challenging life conditions. The aim of this study was to compare depressive symptoms, social support, and resilience between Japanese company workers who engaged in regular physical exercise and workers who did not exercise regularly. We also investigated whether regular physical exercise has an indirect association with depressive symptoms through social support and resilience. Methods Participants were 715 Japanese employees at six worksites. Depressive symptoms were assessed with the Center for Epidemiologic Studies Depression (CES-D scale, social support with the short version of the Social Support Questionnaire (SSQ, and resilience with the 14-item Resilience Scale (RS-14. A self-report questionnaire, which was extracted from the Japanese version of the Health-Promoting Lifestyle Profile, was used to assess whether participants engage in regular physical exercise, defined as more than 20 min, three or more times per week. The group differences in CES-D, SSQ, and RS-14 scores were investigated by using analysis of covariance (ANCOVA. Mediation analysis was conducted by using Preacher and Hayes’ bootstrap script to assess whether regular physical exercise is associated with depressive symptoms indirectly through resilience and social support. Results The SSQ Number score (F = 4.82, p = 0.03, SSQ Satisfaction score (F = 6.68, p = 0.01, and RS-14 score (F = 6.01, p = 0.01 were significantly higher in the group with regular physical exercise (n = 83 than in the group without regular physical exercise (n = 632 after adjusting for age, education, marital status, and job status. The difference in CES-D score was not significant (F = 2.90, p = 0

    Systematic reviews have the potential to contribute substantially to environmental health and risk assessment. This study aimed to investigate indoor air quality of environments used for physical exercise and sports practice through a systematic review. The systematic review followed the PRISMA guidelines and was recorded in the PROSPERO registry (CRD42016036057). The search was performed using the SciELO, Science Direct, Scopus, LILACS, MEDLINE via PubMed, and SPORTDiscus databases, from their inception through April 2017. The search terms used in the databases were {air pollution" OR "air pollutants" OR "air quality"} AND {"physical exercise" OR "physical activity" OR "sport"}. The results of selected studies were divided into 5 categories for analysis: monitoring of air quality in the environment according to international guidelines, indoor-to-outdoor ratio (I/O), air quality during physical exercise, impact of air quality on health, and interventions to improve indoor air quality. Among 1281 studies screened, 34 satisfied the inclusion criteria. The monitoring of pollutants was conducted in 20 studies. CO and NO 2 were the most investigated pollutants, and guidelines were discussed in most studies. The I/O ratio was investigated in 12 studies, of which 9 showed a higher concentration of some pollutants in indoor rather than outdoor environments. Among the 34 studies selected, only 7 investigated the impact of indoor air pollution on human health. The population in most of these studies consisted of hockey players. Most studies conducted monitoring of pollutants in indoor environments used for physical exercise and sports practice. The earliest studies were conducted in ice skating rinks and the most recent evaluated gymnasiums, fitness centers, and sports centers. The CO, particulate matter, and NO 2 concentrations were the most investigated and have the longest history of investigation. These pollutants were within the limits established by guidelines in most

    The objectives of this study were (1) to evaluate the long-term effects of a lifestyle physical activity intervention (n = 60) and a structured exercise intervention (n = 60) on physical self-perceptions and self-esteem in older adults compared with a control group (n = 66), and (2) to test the longitudinal fit of the exercise and self-esteem model (EXSEM). Immediately after the 11-month interventions, the lifestyle group showed significant improvements in self-perceived physical condition, sport competence, body attractiveness, and physical self-worth. In the structured group, significant effects were found on physical condition and sport competence. One year later, the lifestyle program had significant effects on body attractiveness and global self-esteem, while the structured group showed significant improvements in physical condition, sport competence, and body attractiveness. Path analyses revealed a good fit for the EXSEM across the 2-year period.

    Many individuals do not engage in sufficient physical activity due to low perceived benefits and high perceived barriers to exercise. Given the increasing incidence of obesity and obesity related health disorders, this topic requires further exploration. We used the Exercise Benefits/Barriers Scale to assess perceived benefit and barrier intensities to exercise in 200 non-exercising female university students (mean age 19.3 years, SD = 1.06) in the UK. Although our participants were selected because they self reported themselves to be non-exercising, however they reported significantly higher perceived benefits from exercise than perceived barriers to exercise [t(199) = 6.18, p exercise was physical performance followed by the benefits of psychological outlook, preventive health, life enhancement, and then social interaction. Physical performance was rated significantly higher than all other benefits. Psychological outlook and preventive health were not rated significantly different, although both were significantly higher than life enhancement and social interaction. Life enhancement was also rated significantly higher than social interaction. The greatest perceived barrier to exercise was physical exertion, which was rated significantly higher than time expenditure, exercise milieu, and family discouragement barriers. Implications from this investigation for the design of physical activity programmes include the importance, for females, of a perception of high benefit/barrier ratio that could be conducive to participation in exercise. Applied interventions need to assist female students to 'disengage' from or overcome any perceived 'unpleasantness' of physical exertion during physical activity (decrease their perceived barriers), and to further highlight the multiple health and other benefits of regular exercising (increase their perceived benefits).

    International evidence-based guidelines recommend physical exercise to form part of standard care for all cancer survivors. However, at present, the optimum exercise intensity is unclear. Therefore, we aimed to evaluate the effectiveness of a high intensity (HI) and low-to-moderate intensity (LMI) resistance and endurance exercise program compared with a wait list control (WLC) group on physical fitness and fatigue in a mixed group of cancer survivors who completed primary cancer treatment, including chemotherapy. Overall, 277 cancer survivors were randomized to 12 weeks of HI exercise (n = 91), LMI exercise (n = 95), or WLC (n = 91). Both interventions were identical with respect to exercise type, duration and frequency, and only differed in intensity. Measurements were performed at baseline (4-6 weeks after primary treatment) and post-intervention. The primary outcomes were cardiorespiratory fitness (peakVO2), muscle strength (grip strength and 30-second chair-stand test), and self-reported fatigue (Multidimensional Fatigue Inventory; MFI). Secondary outcomes included health-related quality of life, physical activity, daily functioning, body composition, mood, and sleep disturbances. Multilevel linear regression analyses were performed to estimate intervention effects using an intention-to-treat principle. In the HI and LMI groups, 74 % and 70 % of the participants attended more than 80 % of the prescribed exercise sessions, respectively (P = 0.53). HI (β = 2.2; 95 % CI, 1.2-3.1) and LMI (β = 1.3; 95 % CI, 0.3-2.3) exercise showed significantly larger improvements in peakVO2 compared to WLC. Improvements in peakVO2 were larger for HI than LMI exercise (β = 0.9; 95 % CI, -0.1 to 1.9), but the difference was not statistically significant (P = 0.08). No intervention effects were found for grip strength and the 30-second chair-stand test. HI and LMI exercise significantly reduced general and physical fatigue and reduced activity

    Exercise in natural environments ("green exercise") confers numerous health benefits, but little is known about why people engage in green exercise. This study examined the importance of nature experiences as a motive for physical activity and the motivational profile of people who engage in green exercise compared to gym- and sports-based exercise. Physical activity motives and typical times spent in different domains of physical activity were reported by 2168 Norwegian adults in a survey. Experiencing nature was generally rated as the second-most important physical activity motive, exceeded only by convenience motives, and it was especially important for older adults and those who engage in greater amounts of instrumental physical activity. Green exercisers reported stronger motives concerning convenience and experiencing nature, whereas gym- or sports-based exercisers reported stronger motives for physical health and sociability. The motives associated with different leisure-time exercise domains may assist in understanding optimal promotion of green exercise.

  12. Effect of workplace- versus home-based physical exercise on pain in healthcare workers: study protocol for a single blinded cluster randomized controlled trial

    Science.gov (United States)

    2014-01-01

    Background The prevalence and consequences of musculoskeletal pain is considerable among healthcare workers, allegedly due to high physical work demands of healthcare work. Previous investigations have shown promising results of physical exercise for relieving pain among different occupational groups, but the question remains whether such physical exercise should be performed at the workplace or conducted as home-based exercise. Performing physical exercise at the workplace together with colleagues may be more motivating for some employees and thus increase adherence. On the other hand, physical exercise performed during working hours at the workplace may be costly for the employers in terms of time spend. Thus, it seems relevant to compare the efficacy of workplace- versus home-based training on musculoskeletal pain. This study is intended to investigate the effect of workplace-based versus home-based physical exercise on musculoskeletal pain among healthcare workers. Methods/Design This study was designed as a cluster randomized controlled trial performed at 3 hospitals in Copenhagen, Denmark. Clusters are hospital departments and hospital units. Cluster randomization was chosen to increase adherence and avoid contamination between interventions. Two hundred healthcare workers from 18 departments located at three different hospitals is allocated to 10 weeks of 1) workplace based physical exercise performed during working hours (using kettlebells, elastic bands and exercise balls) for 5 × 10 minutes per week and up to 5 group-based coaching sessions, or 2) home based physical exercise performed during leisure time (using elastic bands and body weight exercises) for 5 × 10 minutes per week. Both intervention groups will also receive ergonomic instructions on patient handling and use of lifting aides etc. Inclusion criteria are female healthcare workers working at a hospital. Average pain intensity (VAS scale 0-10) of the back, neck and shoulder

    Individuals with elevated levels of anxiety sensitivity (AS) may be motivated to avoid aversive emotional or physical states, and therefore may have greater difficulty achieving healthy behavioral change. This may be particularly true for exercise, which produces many of the somatic sensations within the domain of AS concerns. Cross-sectional studies show a negative association between AS and exercise. However, little is known about how AS may prospectively affect attempts at behavior change in individuals who are motivated to increase their exercise. We recruited 145 young adults who self-identified as having a desire to increase their exercise behavior. Participants completed a web survey assessing AS and additional variables identified as important for behavior change-impulsivity, grit, perceived behavioral control, and action planning-and set a specific goal for exercising in the next week. One week later, a second survey assessed participants' success in meeting their exercise goals. We hypothesized that individuals with higher AS would choose lower exercise goals and would complete less exercise at the second survey. AS was not significantly associated with exercise goal level, but significantly and negatively predicted exercise at Time 2 and was the only variable to offer significant prediction beyond consideration of baseline exercise levels. These results underscore the importance of considering AS in relation to health behavior intentions. This is particularly apt given the absence of prediction offered by other traditional predictors of behavior change. © The Author(s) 2015.

  14. Performance related factors are the main determinants of the von Willebrand factor response to exhaustive physical exercise.

    Full Text Available Physical stress triggers the endothelium to release von Willebrand Factor (VWF from the Weibel Palade bodies. Since VWF is a risk factor for arterial thrombosis, it is of great interest to discover determinants of VWF response to physical stress. We aimed to determine the main mediators of the VWF increase by exhaustive physical exercise.105 healthy individuals (18-35 years were included in this study. Each participant performed an incremental exhaustive exercise test on a cycle ergometer. Respiratory gas exchange measurements were obtained while cardiac function was continuously monitored. Blood was collected at baseline and directly after exhaustion. VWF antigen (VWF:Ag levels, VWF collagen binding (VWF:CB levels, ADAMTS13 activity and common variations in Syntaxin Binding Protein-5 (STXBP5, rs1039084 and rs9399599, Syntaxin-2 (STX2, rs7978987 and VWF (promoter, rs7965413 were determined.The median VWF:Ag level at baseline was 0.94 IU/mL [IQR 0.8-1.1] and increased with 47% [IQR 25-73] after exhaustive exercise to a median maximum VWF:Ag of 1.38 IU/mL [IQR 1.1-1.8] (p<0.0001. VWF:CB levels and ADAMTS13 activity both also increased after exhaustive exercise (median increase 43% and 12%, both p<0.0001. The strongest determinants of the VWF:Ag level increase are performance related (p<0.0001. We observed a gender difference in VWF:Ag response to exercise (females 1.2 IU/mL; males 1.7 IU/mL, p = 0.001, which was associated by a difference in performance. Genetic variations in STXBP5, STX2 and the VWF promoter were not associated with VWF:Ag levels at baseline nor with the VWF:Ag increase.VWF:Ag levels strongly increase upon exhaustive exercise and this increase is strongly determined by physical fitness level and the intensity of the exercise, while there is no clear effect of genetic variation in STXBP5, STX2 and the VWF promoter.

    Increases in clinical complications associated with maternal obesity have generated interest in increasing physical activity (PA) and exercise levels as an intervention to improve pregnancy outcomes. The objective of this study was to examine the relationship between BMI categorisation and PA and exercise levels as pregnancy advances. This was an observational study in a large university maternity hospital. Women were recruited at their convenience before they left hospital after delivering a baby weighing 500 g or more. They completed a detailed customised physical activity and exercise questionnaire. BMI categorisation was based on the measurement of weight and height in early pregnancy. Of the 155 women recruited, 42.5 % (n = 66) were primigravidas and 10.3 % (n = 16) were smokers. Mean Body Mass Index (BMI) was 24.6 kg/m(2) and 14.2 % (n = 22) were obese, based on a BMI >29.9 kg/m(2). Overall, women decreased their exercise from an average 194 min (range 0-650 min) per week pre-pregnancy to 98 min antenatally (range 0-420 min) (p Obese women exercised least pre-pregnancy and antenatally at 187.5 and 75 min per week, respectively, compared with 193.2 and 95.5 min per week in the normal BMI group and 239.3 and 106.7 min per week in the overweight group. The mean gestation at which all women reduced their activity levels was 29 weeks. We found that women decreased their PA  and exercise levels significantly in the third trimester and, thus, in the absence of a medical contra-indication there is considerable scope for an exercise intervention to improve activity  and exercise levels as pregnancy advances. However, an increase in PA levels in obese women needs further studies to determine whether it will improve the clinical outcomes for the woman and her offspring.

    This study used a path analysis approach to examine the relationship between feelings of energy, exercise-related self-efficacy beliefs, and exercise participation. A cross-sectional mailing survey design was used to measure feelings of physical and mental energy, task and scheduling self-efficacy beliefs, and voluntary moderate and vigorous exercise participation in 368 healthy, full-time undergraduate students (mean age = 21.43 ± 2.32 years). The path analysis revealed that the hypothesized path model had a strong fit to the study data. The path model showed that feelings of physical energy had significant direct effects on task and scheduling self-efficacy beliefs as well as exercise behaviors. In addition, scheduling self-efficacy had direct effects on moderate and vigorous exercise participation. However, there was no significant direct relationship between task self-efficacy and exercise participation. The path model also revealed that scheduling self-efficacy partially mediated the relationship between feelings of physical energy and exercise participation.

    We investigated the impact of exercise and vitamin D supplementation on physical function and locomotor dysfunction in community-dwelling elderly individuals. In total, 148 community-dwelling elderly individuals (aged ≥60 years) who were not taking osteoporosis medications participated in a 24-week intervention. The participants were randomly divided into an exercise group, vitamin D group, and exercise and vitamin D group. The participants and outcome-assessing staff were not blinded to group assignment. Exercise comprised three daily sets each of single-leg standing (1 min/leg/set) and squatting (5-6 repetitions/set); vitamin D supplementation was 1000 IU/day. Participants were contacted every 2 weeks to check on their condition and encourage continued participation. The primary outcome was lower limb muscle strength and mass; secondary outcomes were several physical function measurements, serum 25-hydroxyvitamin D levels, and results of a self-assessment questionnaire completed pre- and post-intervention. We analyzed data from 45, 42, and 43 participants in the exercise, vitamin D, and exercise and vitamin D groups, respectively, who completed the intervention. Locomotive syndrome, which involves reduced mobility due to locomotive organ impairment, was diagnosed in 99 participants (76.2%). Many physical function measurements improved in all groups. Lower limb muscle mass increased significantly in all three groups, with no significant differences between the groups in the degree of change. The average serum 25-hydroxyvitamin D of all vitamin D-supplemented participants increased from 28.1 ng/ml to 47.3 ng/ml after vitamin D supplementation. Both exercise and vitamin D supplementation independently improved physical function and increased muscle mass in community-dwelling elderly individuals. Moreover, the combination of exercise and vitamin D supplementation might further enhance these positive effects. UMIN Clinical Trial, UMIN000028229. Copyright © 2018

    Exercise is considered an important component of a healthy lifestyle but there remains controversy on effects of exercise on non-exercise physical activity (PA). The present study examined the prospective association of aerobic and resistance exercise with total daily energy expenditure and PA in previously sedentary, young men. Nine men (27.0 ± 3.3 years) completed two 16-week exercise programs (3 exercise sessions per week) of aerobic and resistance exercise separated by a minimum of 6 weeks in random order. Energy expenditure and PA were measured with the SenseWear Mini Armband prior to each intervention as well as during week 1, week 8 and week 16 of the aerobic and resistance exercise program. Body composition was measured via dual x-ray absorptiometry. Body composition did not change in response to either exercise intervention. Total daily energy expenditure on exercise days increased by 443 ± 126 kcal/d and 239 ± 152 kcal/d for aerobic and resistance exercise, respectively (p change in total daily energy expenditure and PA on non-exercise days with aerobic exercise while resistance exercise was associated with an increase in moderate-to-vigorous PA during non-exercise days (216 ± 178 kcal/d, p = 0.01). Results of the present study suggest a compensatory reduction in PA in response to aerobic exercise. Resistance exercise, on the other hand, appears to facilitate non-exercise PA, particularly on non-exercise days, which may lead to more sustainable adaptations in response to an exercise program.

  1. Using probability density function in the procedure for recognition of the type of physical exercise

    Full Text Available This paper presents a method for recognition of physical exercises, using only a triaxial accelerometer of a smartphone. The smartphone itself is free to move inside subject's pocket. Exercises for leg muscle strengthening from subject's standing position squat, right knee rise and lunge with right leg were analyzed. All exercises were performed with the accelerometric sensor of a smartphone placed in the pocket next to the leg used for exercises. In order to test the proposed recognition method, the knee rise exercise of the opposite leg with the same position of the sensor was randomly selected. Filtering of the raw accelerometric signals was carried out using Butterworth tenth-order low-pass filter. The filtered signals from each of the three axes were described using three signal descriptors. After the descriptors were calculated, a probability density function was constructed for each of the descriptors. The program that implemented the proposed recognition method was executed online within an Android application of the smartphone. Signals from two male and two female subjects were considered as a reference for exercise recognition. The exercise recognition accuracy was 94.22% for three performed exercises, and 85.33% for all four considered exercises.

    To examine cross-sectional and longitudinal associations between physical exercise and cognitive function across different age groups in a nationwide population-based sample of adults aged 18-79 years in Germany. Cross-sectional/prospective. Cognitive function was assessed in the mental health module of the German Health Interview and Examination Survey for Adults (DEGS1-MH, 2009-2012, n=3535), using a comprehensive neuropsychological test battery. Cognitive domain scores for executive function and memory were derived from confirmatory factor analysis. Regular physical exercise in the last three months was assessed by self-report and defined as no exercise, function in cross-sectional (function and memory in cross-sectional and longitudinal analyses with no evidence for differential effects by age.

    The aim of this review was to recommend training strategies that improve the functional capacity in physically frail older adults based on scientific literature, focusing specially in supervised exercise programs that improved muscle strength, fall risk, balance, and gait ability. Scielo, Science Citation Index, MEDLINE, Scopus, Sport Discus, and ScienceDirect databases were searched from 1990 to 2012. Studies must have mentioned the effects of exercise training on at least one of the following four parameters: Incidence of falls, gait, balance, and lower-body strength. Twenty studies that investigated the effects of multi-component exercise training (10), resistance training (6), endurance training (1), and balance training (3) were included in the present revision. Ten trials investigated the effects of exercise on the incidence of falls in elderly with physical frailty. Seven of them have found a fewer falls incidence after physical training when compared with the control group. Eleven trials investigated the effects of exercise intervention on the gait ability. Six of them showed enhancements in the gait ability. Ten trials investigated the effects of exercise intervention on the balance performance and seven of them demonstrated enhanced balance. Thirteen trials investigated the effects of exercise intervention on the muscle strength and nine of them showed increases in the muscle strength. The multi-component exercise intervention composed by strength, endurance and balance training seems to be the best strategy to improve rate of falls, gait ability, balance, and strength performance in physically frail older adults.

    Obesity and a sedentary lifestyle are associated with physical impairments and biologic changes in older adults. Weight loss combined with exercise may reduce inflammation and improve physical functioning in overweight, sedentary, older adults. This study tested whether a weight loss program combined with moderate exercise could improve physical function in obese, older adult women. Participants (N = 34) were generally healthy, obese, older adult women (age range 55-79 years) with mild to moderate physical impairments (ie, functional limitations). Participants were randomly assigned to one of two groups for 24 weeks: (i) weight loss plus exercise (WL+E; n = 17; mean age = 63.7 years [4.5]) or (ii) educational control (n = 17; mean age = 63.7 [6.7]). In the WL+E group, participants attended a group-based weight management session plus three supervised exercise sessions within their community each week. During exercise sessions, participants engaged in brisk walking and lower-body resistance training of moderate intensity. Participants in the educational control group attended monthly health education lectures on topics relevant to older adults. Outcomes were: (i) body weight, (ii) walking speed (assessed by 400-meter walk test), (iii) the Short Physical Performance Battery (SPPB), and (iv) knee extension isokinetic strength. Participants randomized to the WL+E group lost significantly more weight than participants in the educational control group (5.95 [0.992] vs 0.23 [0.99] kg; P meter walk test = 44 seconds; P < 0.05). Scores on the SPPB improved in both the intervention and educational control groups from pre- to post-test (P < 0.05), with significant differences between groups (P = 0.02). Knee extension strength was maintained in both groups. Our findings suggest that a lifestyle-based weight loss program consisting of moderate caloric restriction plus moderate exercise can produce significant weight loss and improve physical function while maintaining muscle

    Although exercise-induced feeling states may play a role in driving future behavior, their role in relation to older adults' participation in physical activity (PA) has seldom been considered. The objectives of this study were to describe changes in older adults' feeling states during exercise, and examine if levels of and changes in feeling states predicted their future participation in PA. Self-reported data on feeling states were collected from 82 older adults immediately before, during, and after a moderate-intensity exercise session, and on participation in PA 1 month later. Data were analyzed using latent growth modeling. Feelings of revitalization, positive engagement, and tranquility decreased during exercise, whereas feelings of physical exhaustion increased. Feelings of revitalization immediately before the exercise session predicted future participation in PA; changes in feeling states did not. This study does not provide empirical evidence that older adults' exercise-induced feeling states predict their future participation in PA.

    As part of a biomechanics course aimed at upper-division biology and physics majors, but applicable to a range of student learning levels, this laboratory exercise provides an insight into the effect of shape on hydrodynamic performance, as well an introduction to computer aided design (CAD) and 3D printing. Students use hydrodynamic modeling software and simple CAD programs to design a shape with the least amount of drag based on strategies gleaned from the study of natural forms. Students then print the shapes using a 3D printer and test their shapes against their classmates in a friendly competition. From this exercise, students gain a more intuitive sense of the challenges that organisms face when moving through fluid environments, the physical phenomena involved in moving through fluids at high Reynolds numbers and observe how and why certain morphologies, such as streamlining, are common answers to the challenge of swimming at high speeds.

    Lack of physical activity is a major contributing factor to the worldwide obesity epidemic, and to the overall burden of disease. The deindustrialisation of developed economies and move to more sedentary employment has impacted on the opportunities of working individuals to participate in physical activity. This can have negative effects on productivity and worker health potentially influencing economic growth. Thus, it is important to determine the factors influencing the frequency of participation in physical activity for employed individuals. This paper uses a modified time allocation framework to explore this issue. We use data from the first six waves of the Household Income and Labour Dynamics of Australia survey (HILDA). The analysis examines frequency of participation in physical activity using a generalised random effects ordered probit model. We control for non-parallel cut-points between the physical activity categories and individual heterogeneity, as well as exploring differences across gender. The results indicate that there is a time trade-off between non-market work, market work, and the frequency of physical activity participation. This effect is moderated by gender. For example, dependent children have a larger negative effect on the frequency of physical activity participation for women. Education and marriage have a larger negative effect on the frequency of participation for men. The findings suggests that policies which make exercise more convenient, and hence decrease the opportunity cost of exercise, will help to encourage more frequent participation in physical activity for working adults.

    According to the UN, the number of elderly people over the age of 60 will reach 2 billion by 2050. Aging is accompanied with functional and cognitive decline that impact elderly independence and quality of life. This often results in issues such as forgetting, fall, and depression. Physical exercises can help. However, only 16% of elderly above the age 65 years do enough exercise to meet HHS (Department of Health and Human Services) physical activity guidelines for Americans. Several barriers...

    Bachelor of physics lectures on ‘Particle Physics and Astrophysics’ were complemented by exercises related to data analysis and data interpretation at the RWTH Aachen University recently. The students performed these exercises using the internet platform VISPA, which provides a development environment for physics data analyses. We describe the platform and its application within the physics course, and present the results of a student survey. The students’ acceptance of the learning project was positive. The level of acceptance was related to their individual preference for learning with a computer. Furthermore, students with good programming skills favour working individually, while students who attribute themselves as having low programming abilities favour working in teams. The students appreciated approaching actual research through the data analysis tasks. (paper)
