Preparing medical students to prescribe is a major challenge of undergraduate education. They must develop an understanding of clinical pharmacology and acquire knowledge about drugs and therapeutics, as well as the skills to prescribe for individual patients in the face of multiple variables. The task of delivering the learning required to achieve these attributes relies upon limited numbers of teachers, who have increasingly busy clinical commitments. There is evidence that training is currently insufficient to meet the demands of the workplace. e-Learning provides an opportunity to improve the learning experience. The advantages for teachers are improved distribution of learning content, ease of update, standardization and tracking of learner activities. The advantages for learners are ease of access, greater interactivity and individual choice concerning the pace and mix of learning. Important disadvantages are the considerable resource required to develop e-Learning projects and difficulties in simulating some aspects of the real world prescribing experience. Pre-requisites for developing an e-Learning programme to support prescribing include academic expertise, institutional support, learning technology services and an effective virtual learning environment. e-Learning content might range from complex interactive learning sessions through to static web pages with links. It is now possible to simulate and provide feedback on prescribing decisions and this will improve with advances in virtual reality. Other content might include a student formulary, self-assessment exercises (e.g. calculations), a glossary and an on-line library. There is some evidence for the effectiveness of e-Learning but better research is required into its potential impact on prescribing. PMID:22509885

Full Text Available Background: Post surgical mitral valve disease individual focus their cardiac rehabilitation training on two major goal that is to improve cardiac output response exercises and place an important role in determining exercise tolerance and to improve quality of life. Cardiac rehabilitation programs involve prescribed exercise and education however various other method are being used to improve quality of life. But our study to find out the effectiveness of graded aerobic exercise protocol on ejection fraction and quality of life in post surgical mitral valve disease individuals. Methods: The study design was open label studies total of 100 post surgical mitral valve disease individuals patients from the age group of 20-60 years were recruited from SVIMS hospital. They were randomly divided into two groups. Group I underwent a twelve week structured graded individually tailored exercises. The group II received only none graded (not individualized exercise training. The ejection fraction and quality of life was measured before and after 12 weeks of exercise training for two groups. Results: Repeated measures ANOVA was used to compare mean values of continuous variables between baseline and at the time of discharge and three months after surgery for each parameter. Comparison of means between groups was done by the unpaired student t test. Mean age of the subjects was 40.18±10.29. There was a significant increase in the ejection fraction in the group I(61.34±2.49 to 64.4±3.31 compared to with the group II (61.06±2.51. to 61.62 ±2.37. QOL had improved in group I than group II at p<0.05. Conclusion: A 12 week structured graded aerobic exercise training significantly improved ejection fraction and quality of life in post surgical mitral valve disease individuals.

Laricy Martins da Mata

Full Text Available Abstract Introduction: Despite the prevalence of prescribed asthma, there is uncertainty about the incidence of exercise-induced bronchospasm (EIB. Objective: Compare the frequency of EIB between swimmers and sedentary individuals, and observe heart rate variability during bronchial activity. Methods: In total, 18 swimmers (group 1 and 18 sedentary individuals (group 2 were included. The participants rested for 30 minutes for evaluation of HRV. Blood pressure (PA, respiratory rate (RR, and pulse oxygen saturation (SpO2 were measured. The volunteers remained seated for the spirometry test (maneuver of forced vital capacity - FVC. This was repeated 5, 10, 15, 20, and 30 minutes after the exercise test. The statistical analysis used the Student t, Mann Whitney, and Shapiro-Wilks tests. The significance level was p <0.05. Results: The spirometry findings showed 3 sedentary individuals and 10 swimmers with obstructive ventilatory disorder (OVD. Only 2 of the sedentary and none of the swimmer group demonstrated positive bronchial provocation. A key criterion for diagnosing OVD, the relationship between forced expiratory volume in one second and FVC (FEV1/FVC, was statistically lower in the swimmer group. The measures of the root mean square of the successive differences between adjacent normal RR intervals, in a time interval (RMSSD, and the standard deviation of all normal RR intervals recorded in a time interval (SDNN were significantly higher among the athletes. Conclusion: The bronchial provocation test identified a higher prevalence of bronchospasm among sedentary individuals. However, there was a reduction in the FEV1/FVC ratio and higher HRV in the group of swimmers.

Diurnal preference (and chronotype more generally) has been implicated in exercise behavior, but this relation has not been examined using objective exercise measurements nor have potential psychosocial mediators been examined. Furthermore, time-of-day often moderates diurnal preference's influence on outcomes, and it is unknown whether time-of-exercise may influence the relation between chronotype and exercise frequency. The current study examined whether individual differences in diurnal preference ("morningness-eveningness") predict unique variance in exercise frequency and if commonly studied psychosocial variables mediate this relation (i.e., behavioral intentions, internal exercise control, external exercise control, and conscientiousness). Moreover, the study sought to test whether individuals' typical time-of-exercise moderated the impact of diurnal preference on exercise frequency. One hundred twelve healthy adults (mean age = 25.4; SD = 11.6 years) completed baseline demographics and then wore Fitbit Zips® for 4 weeks to objectively measure exercise frequency and typical time-of-exercise. At the end of the study, participants also self-reported recent exercise. Diurnal preference predicted both self-reported exercise and Fitbit-recorded exercise frequency. When evaluating mediators, only conscientiousness emerged as a partial mediator of the relation between diurnal preference and self-reported exercise. In addition, time-of-exercise moderated diurnal preference's relation to both self-reported exercise and Fitbit-recorded exercise frequency such that diurnal preference predicted higher exercise frequency when exercise occurred at a time that was congruent with one's diurnal preference. Based on these findings, diurnal preference is valuable, above and beyond other psychological constructs, in predicting exercise frequency and represents an important variable to incorporate into interventions seeking to increase exercise.

Full Text Available Purpose. Studies have shown that even a single session of physical exercise lowers blood pressure after its completion. This phenomenon is called post-exercise hypotension (PEH and has been considered as a non-pharmacological treatment to control blood pressure. However, there are no studies regarding the occurrence of PEH after acute exercise in individuals with Down syndrome (DS. This study aimed to analyse the occurrence of PEH in these subjects and the possible role of exercise intensity. Methods. Ten individuals with DS, of both genders, participated in the study (age, 29 ± 7 years; body mass, 60.7 ± 9 kg; height, 1.48 ± 0.11 m; BMI, 27.6 ± 2.4 kg/m2. The volunteers randomly underwent 2 sessions of exercise on a stationary bike for 20 minutes and 1 control session. Heart rate, systolic blood pressure (SBP and diastolic blood pressure (DBP were measured after 15 minutes of resting, in the 20th minute of each exercise session or control, and in the 15th, 30th, and 45th minute of postexercise recovery. Results. Both moderate and intense exercise performed acutely increased SBP (p < 0.001, p < 0.01, respectively, with no effect on DBP in individuals with DS. Neither the moderate nor the intense exercise was enough to elicit PEH. Conclusions. The results indicated that individuals with DS may not present PEH for the intensities, duration, and exercise mode as applied in the present investigation. While additional studies with different exercise strategies are needed, our findings contribute to the body of literature regarding the PEH responses in adults with DS.

This study investigated the differences in exercise self-efficacy, compliance, and effectiveness of home-based exercise in individuals with and without metabolic syndrome (MetS). One hundred and ten individuals at risk for diabetes participated in this study. Subjects were categorized into individuals with MetS and individuals without MetS. Metabolic risk factors and exercise self-efficacy were evaluated for all subjects before and after 3 months of home-based exercise. Univariate analysis of variance was used to compare the effectiveness of a home-based exercise program between individuals with and without MetS. The home-based exercise program improved body mass index and lipid profile in individuals at risk for diabetes, regardless of MetS status at baseline. Individuals without MetS had higher exercise self-efficacy at baseline and performed greater exercise volume compared with individuals with MetS during the intervention. The increased exercise volume in individuals without MetS may contribute to their better control of insulin resistance than individuals with MetS. Furthermore, baseline exercise self-efficacy was correlated with exercise volume executed by subjects at home. We conclude that home-based exercise programs are beneficial for individuals at risk for diabetes. However, more intensive and/or supervised exercise intervention may be needed for those with MetS.

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.

Browne, Julia; Mihas, Paul; Penn, David L

2016-05-01

The health benefits of exercise are well established, yet individuals with serious mental illness (SMI) have a shorter life expectancy due in large part to physical health complications associated with poor diet and lack of exercise. There is a paucity of research examining exercise in this population with the majority of studies having examined interventions with limited feasibility and sustainability. Before developing an intervention, a thorough exploration of client and clinician perspectives on exercise and its associated barriers is warranted. Twelve clients and fourteen clinicians participated in focus groups aimed at examining exercise, barriers, incentives, and attitudes about walking groups. Results indicated that clients and clinicians identified walking as the primary form of exercise, yet barriers impeded consistent participation. Distinct themes arose between groups; however, both clients and clinicians reported interest in a combination group/pedometer based walking program for individuals with SMI. Future research should consider examining walking programs for this population.

Exercise recommendations for individuals with spinal cord injury.

Jacobs, Patrick L; Nash, Mark S

2004-01-01

Persons with spinal cord injury (SCI) exhibit deficits in volitional motor control and sensation that limit not only the performance of daily tasks but also the overall activity level of these persons. This population has been characterised as extremely sedentary with an increased incidence of secondary complications including diabetes mellitus, hypertension and atherogenic lipid profiles. As the daily lifestyle of the average person with SCI is without adequate stress for conditioning purposes, structured exercise activities must be added to the regular schedule if the individual is to reduce the likelihood of secondary complications and/or to enhance their physical capacity. The acute exercise responses and the capacity for exercise conditioning are directly related to the level and completeness of the spinal lesion. Appropriate exercise testing and training of persons with SCI should be based on the individual's exercise capacity as determined by accurate assessment of the spinal lesion. The standard means of classification of SCI is by application of the International Standards for Classification of Spinal Cord Injury, written by the Neurological Standards Committee of the American Spinal Injury Association. Individuals with complete spinal injuries at or above the fourth thoracic level generally exhibit dramatically diminished cardiac acceleration with maximal heart rates less than 130 beats/min. The work capacity of these persons will be limited by reductions in cardiac output and circulation to the exercising musculature. Persons with complete spinal lesions below the T(10) level will generally display injuries to the lower motor neurons within the lower extremities and, therefore, will not retain the capacity for neuromuscular activation by means of electrical stimulation. Persons with paraplegia also exhibit reduced exercise capacity and increased heart rate responses (compared with the non-disabled), which have been associated with circulatory limitations

BACKGROUND: Patellofemoral pain is one of the most frequent knee conditions among adolescents with a prevalence of 7 %. Evidence-based treatment consists of patient education combined with hip and quadriceps strengthening. Recent evidence suggests that a large proportion of adolescents does...... not follow their exercise prescription, performing too few repetitions or too fast below the prescribed time under tension. Live feedback, such as a metronome or exercise games, has previously shown promising results in improving the quality of exercises. The aim of this study is to investigate if live...... feedback from a sensor (BandCizer™) and an iPad will improve the ability of adolescents with PFP to perform exercises as prescribed. METHODS: This study is a randomized, controlled, participant-blinded, superiority trial with a 2-group parallel design. Forty 15 to 19 year old adolescents...

2015-07-01

Parenteral nutrition (PN) is available as individualized prescriptions frequently prepared with an automated compounding device or as commercially prepared premixed solutions. Our institution exclusively used individualized PN until an amino acid shortage forced a temporary switch to premixed solutions. In general, premixed solutions contain lower electrolyte levels than individualized formulations prescribed for patients with normal organ function. We aimed to quantify supplemental intravenous piggyback (IVPB) electrolyte use in adult patients receiving individualized and premixed PN and to quantify any effect on difference in the cost of therapy. We compared use of supplemental IVPB electrolytes administered to patients receiving PN during consecutive periods prior to and during the amino acid shortage. Electrolyte IVPBs tabulated were potassium chloride, 10 and 20 mEq; magnesium sulfate, 2 g and 4 g; potassium phosphate, 7.5 and 15 mmol; and sodium phosphate, 7.5 and 15 mmol IVPB. There was no statistical difference in the number of PN formulations administered per day during each period (14.7 ± 3.9 vs 14.0 ± 2.6, individualized vs premixed, respectively). Total IVPB electrolytes prescribed per day increased significantly from the individualized PN period to the premixed PN period (7.03 ± 3.8 vs 13.8 ± 6.8; P Parenteral and Enteral Nutrition.

To evaluate the specific effects of general dynamic water exercise in individuals with late effects of poliomyelitis. Before-after tests. A university hospital department. Twenty-eight individuals with late effects of polio, 15 assigned to the training group (TG) and 13 to the control group (CG). The TG completed a 40-minute general fitness training session in warm water twice weekly. Assessment instruments included the bicycle ergometer test, isokinetic muscle strength, a 30-meter walk indoors, Berg balance scale, a pain drawing, a visual analog scale, the Physical Activity Scale for the Elderly, and the Nottingham Health Profile (NHP). Peak load, peak work load, peak oxygen uptake, peak heart rate (HR), muscle function in knee extensors and flexors, and pain dimension of the NHP. The average training period was 5 months; compliance was 75% (range, 55-98). No negative effects were seen. The exercise did not influence the peak work load, peak oxygen uptake, or muscle function in knee extensors compared with the controls. However, a decreased HR at the same individual work load was seen, as well as a significantly lower distress in the dimension pain of the NHP. Qualitative aspects such as increased well-being, pain relief, and increased physical fitness were reported. A program of nonswimming dynamic exercises in heated water has a positive impact on individuals with late effects of polio, with a decreased HR at exercise, less pain, and a subjective positive experience. The program was well tolerated (no adverse effects were reported) and can be recommended for this group of individuals.

Continuously motivating people to exercise regularly is more important than finding a barriers such as lack of time, cost of equipment or gym membership, lack of nearby facilities and poor weather or night-time lighting. Our proposed system presents practicable methods of motivation through a web-based exercise prescription service. Users are instructed to exercise according to their physical ability by means of an automated individual prescription of exercise checked and approved by a personal trainer or exercise specialist after being tested with the HIMS, fitness assessment system. Furthermore, utilizing BIOFIT exercise prescriptions scheduled by an expert system can help users exercise systematically. Automated individual prescriptions are built in XML based documents because the data needs to be flexible, expansible and convertible structures to process diverse exercise templates. Web-based exercise prescription service makes users stay interested in exercise even if they live in many different environments.

Individualized exercise prescription in non-alcoholic steatohepatitis: a case report

Full Text Available The effect of an individualized exercise programme on a non-alcoholic steatohepatitis case is presented. Before entering the programme the patient was treated with conventional recommendations on diet plus aerobic exercise during fourteen years, without major improvements of his analytical parameters. Two years after including him in a tailored exercise programme, aimed to fulfil the recommendations of the American College of Sports Medicine, his blood markers of liver dysfunction and cardio-metabolic risk tended to improve. Consequently, our data support the idea that in non-alcoholic steatohepatitis the exercise-based therapeutic interventions should be individualized taking into account the cardio-respiratory and muscular fitness of the patient, rather than using generic behavioural recommendations.

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.

We compared mothers who exercised predominantly in group settings, those who exercised predominantly in individual settings, and those who exercised equally in group and individual contexts among the following: (a) satisfaction of basic psychological needs (autonomy, competence, and relatedness); (b) self-determined exercise motivation; and (c) psychological well-being. With clear implications for mothers' exercise interventions we found that exercising either predominantly in group contexts or in mixed group and individual settings was associated with mothers having significantly higher satisfaction of basic psychological needs and self-determined exercise motivation than those exercising predominantly alone.

S. Bernard

2014-03-01

Full Text Available Built around exercise training, pulmonary rehabilitation (PR is a multidisciplinary, evidence‐based, comprehensive approach to working with the patient as a whole and not just the pulmonary component of the disease. Integrated into the individualized treatment, this intervention aims to reduce symptoms, optimize functional status, increase participation in daily life, and reduce health care costs through stabilizing or reversing systemic manifestations of the disease. Although there are many other components that should be considered to manage the impairment and symptom burden, supervised exercise training is considered the cornerstone of effective pulmonary rehabilitation. This paper addresses our clinical experience at Institut universitaire de cardiologie et de pneumologie de Québec to assess and manage exercise training in line with the current recommendations and guidelines surrounding PR. Resumo: Construída com base no exercício físico, a reabilitação pulmonar (RP é uma abordagem multidisciplinar, fundamentada e abrangente para trabalhar com o doente como um todo, e não apenas com a componente pulmonar da doença. Integrado no tratamento individual, esta intervenção visa reduzir os sintomas, optimizar o estado funcional, aumentar a participação na vida diária e reduzir os custos do tratamento de saúde, através da estabilização ou inversão das manifestações sistémicas da doença. Embora existam muitos outros componentes que devem ser tidos em consideração para gerir o peso da incapacidade e dos sintomas, o exercício físico supervisionado é considerado o fundamento da reabilitação pulmonar eficiente.

Accredited Exercise Physiologists (AEPs) are trained to deliver exercise and physical activity interventions for people with chronic and complex health conditions including those with mental illness. However, their views on exercise for mental illness, their exercise prescription practices, and need for further training are unknown. To examine the way in which Australian AEPs prescribe exercise for people with mental illness. Eighty-one AEPs (33.3 ± 10.4 years) completed an online version of the Exercise in Mental Illness Questionnaire. Findings are reported using descriptive statistics. AEPs report a high level of knowledge and confidence in prescribing exercise for people with mental illness. AEPs rate exercise to be at least of equal value to many established treatments for mental illness, and frequently prescribe exercise based on current best-practice principles. A need for additional training was identified. The response rate was low (2.4%) making generalisations from the findings difficult. Exercise prescription practices utilised by AEPs are consistent with current best-practice guidelines and there is frequent consultation with consumers to individualise exercise based on their preferences and available resources. Further training is deemed important.

Low Fat Loss Response after Medium-Term Supervised Exercise in Obese Is Associated with Exercise-Induced Increase in Food Reward

Full Text Available Objective. To examine exercise-induced changes in the reward value of food during medium-term supervised exercise in obese individuals. Subjects/Methods. The study was a 12-week supervised exercise intervention prescribed to expend 500 kcal/day, 5 d/week. 34 sedentary obese males and females were identified as responders (R or non-responders (NR to the intervention according to changes in body composition relative to measured energy expended during exercise. Food reward (ratings of liking and wanting, and relative preference by forced choice pairs for an array of food images was assessed before and after an acute exercise bout. Results. 20 responders and 14 non-responders were identified. R lost 5.2 kg ± 2.4 of total fat mass and NR lost 1.7 kg ± 1.4. After acute exercise, liking for all foods increased in NR compared to no change in R. Furthermore, NR showed an increase in wanting and relative preference for high-fat sweet foods. These differences were independent of 12-weeks regular exercise and weight loss. Conclusion. Individuals who showed an immediate post-exercise increase in liking and increased wanting and preference for high-fat sweet foods displayed a smaller reduction in fat mass with exercise. For some individuals, exercise increases the reward value of food and diminishes the impact of exercise on fat loss.

Little is known about opioid prescribing among individuals who have survived cancer. Our aim is to examine a predominantly socio-economically disadvantaged population for differences in opioid prescribing rates among cancer survivors compared with matched controls without a prior diagnosis of cancer. This was a retrospective population-wide matched cohort study. Starting in 2010, individuals residing in Ontario, Canada, who were 18 to 64 years of age and at least 5 years past their cancer diagnosis were matched to controls without a prior cancer diagnosis based on sex and calendar year of birth. Follow-up was terminated at any indication of cancer recurrence, second malignancy, or new cancer diagnosis. To examine the association between survivorship and the rate of opioid prescriptions, an Andersen-Gill recurrent event regression model was implemented, adjusting for numerous individual-level characteristics and also accounting for the matched design. The rate of opioid prescribing was 1.22 times higher among survivors than among their corresponding matched controls (adjusted relative rate, 1.22; 95% CI, 1.11-1.34). Individuals from lower income quintiles who were younger, were from rural neighborhoods, and had more comorbidities had significantly higher prescribing rates. Sex was not associated with prescribing rates. This increased rate of opioid prescribing was also seen among survivors who were 10 or more years past their cancer diagnosis (compared with their controls). This study demonstrates substantially higher opioid prescribing rates among cancer survivors, even long after attaining survivorship. This raises concerns about the diagnosis and management of chronic pain problems among survivors stemming from their cancer diagnosis or treatment.

Full Text Available Obesity is affecting a growing segment of the population and should be considered a serious health problem which will lead to medical complications and decreased life span. Lifestyle changes by adopting healthy food and increase energy consumption through physical activity is the most important treatment for obesity. Cardiopulmonary exercise test (CPET is considered the gold standard for exercise capacity assessment. Purpose: This study is aiming to demonstrate that individualized exercise training programs, designed using CPET results, leads to increase of physical fitness, aerobic capacity, ventilatory and cardiac exercise performance in young obese subjects.Material and method:We performed a prospective research study of 6 months. 43 sedentary subjects without contraindications to exercise, 21.3±3.1 years old, 93% female were included in the study. Assessments were made at baseline and after six months of intervention and consists of cardiopulmonary exercise test on bicycle ergometer. After we recorded oxygen uptake at aerobic threshold (AT, anaerobic threshold (in the range of respiratory compensation point – RCP and maximal oxygen uptake (VO2max we designed the training program according to these parameters and individualized heart rate training zones of each subject. Exercise training (60 minutes/session, 3 sessions/week was performed taking in consideration the training zones and using a circuit on cardio devices. Each subject was supervised by a physiotherapist and using heart rate monitors. The number of subjects evaluated at the end of the study was 27 (dropout rate 37%.Results:After six months of intervention we noticed an improvement of maximum oxygen uptake (VO2max (from 22.7±3.69 to 27.44±5.55, aerobic threshold (VO2_AT (from 15.48±2.66 to 20.07±4.64 ml/min/kg, p<0.0001 and anaerobic threshold (VO2_RCP (from 20.3±3.66 to 25.11±5.84 ml/min/kg, p<0.0001, cardiac performance during exercise evaluated trough maximal oxygen

To explore the experience of patients and physical therapists with Skype for exercise management of knee osteoarthritis (OA). This was a qualitative study. The Donabedian model for quality assessment in health care (structure, process, and outcomes) informed semistructured individual interview questions. The study involved 12 purposively sampled patients with knee OA who received physical therapist-prescribed exercise over Skype, and all therapists (n = 8) who delivered the intervention in a clinical trial were interviewed about their experiences. Interviews were audio recorded and transcribed. Two investigators undertook coding and analysis using a thematic approach. Six themes arose from both patients and therapists. The themes were Structure: technology (easy to use, variable quality, set-up assistance helpful) and patient convenience (time efficient, flexible, increased access); Process: empowerment to self-manage (facilitated by home environment and therapists focusing on effective treatment) and positive therapeutic relationships (personal undivided attention from therapists, supportive friendly interactions); and Outcomes: satisfaction with care (satisfying, enjoyable, patients would recommend, therapists felt Skype more useful as adjunct to usual practice) and patient benefits (reduced pain, improved function, improved confidence and self-efficacy). A seventh theme arose from therapists regarding process: adjusting routine treatment (need to modify habits, discomfort without hands-on, supported by research environment). Patients and physical therapists described mostly positive experiences using Skype as a service delivery model for physical therapist-supervised exercise management of moderate knee OA. Such a model is feasible and acceptable and has the potential to increase access to supervised exercise management for people with knee OA, either individually or in combination with traditional in-clinic visits. © 2017, American College of Rheumatology.

Full Text Available Cardiorespiratory fitness assessment with leg cycle exercise testing may be influenced by motor impairments in the paretic lower extremity. Hence, this study examined the usefulness of a unilateral arm crank exercise test to assess cardiorespiratory fitness in individuals with stroke, including sixteen individuals with hemiparetic stroke (mean ± SD age, 56.4±7.5 years and 12 age- and sex-matched healthy controls. Participants performed the unilateral arm crank and leg cycle exercise tests to measure oxygen consumption (V˙O2 and heart rate at peak exercise. The V˙O2 at peak exercise during the unilateral arm crank exercise test was significantly lower in the stroke group than in the control group (p<0.001. In the stroke group, the heart rate at peak exercise during the unilateral arm crank exercise test did not significantly correlate with the Brunnstrom recovery stages of the lower extremity (p=0.137, whereas there was a significant correlation during the leg cycle exercise test (rho = 0.775, p<0.001. The unilateral arm crank exercise test can detect the deterioration of cardiorespiratory fitness independently of lower extremity motor impairment severity in individuals with hemiparetic stroke. This study is registered with UMIN000014733.

Maximal fat oxidation (MFO) and the exercise intensity that elicits MFO (Fat Max ) are commonly determined by indirect calorimetry during graded exercise tests in both obese and normal-weight individuals. However, no protocol has been validated in individuals with obesity. Thus, the aims were to develop a graded exercise protocol for determination of Fat Max in individuals with obesity, and to test validity and inter-method reliability. Fat oxidation was assessed over a range of exercise intensities in 16 individuals (age: 28 (26-29) years; body mass index: 36 (35-38) kg·m -2 ; 95% confidence interval) on a cycle ergometer. The graded exercise protocol was validated against a short continuous exercise (SCE) protocol, in which Fat Max was determined from fat oxidation at rest and during 10 min of continuous exercise at 35%, 50%, and 65% of maximal oxygen uptake. Intraclass and Pearson correlation coefficients between the protocols were 0.75 and 0.72 and within-subject coefficient of variation (CV) was 5 (3-7)%. A Bland-Altman plot revealed a bias of -3% points of maximal oxygen uptake (limits of agreement: -12 to 7). A tendency towards a systematic difference (p = 0.06) was observed, where Fat Max occurred at 42 (40-44)% and 45 (43-47)% of maximal oxygen uptake with the graded and the SCE protocol, respectively. In conclusion, there was a high-excellent correlation and a low CV between the 2 protocols, suggesting that the graded exercise protocol has a high inter-method reliability. However, considerable intra-individual variation and a trend towards systematic difference between the protocols reveal that further optimization of the graded exercise protocol is needed to improve validity.

Learning from prescribing errors

 The importance of learning from medical error has recently received increasing emphasis. This paper focuses on prescribing errors and argues that, while learning from prescribing errors is a laudable goal, there are currently barriers that can prevent this occurring. Learning from errors can take place on an individual level, at a team level, and across an organisation. Barriers to learning from prescribing errors include the non-discovery of many prescribing errors, lack of feedback to th...

The purpose of this study was to characterize how resistance exercise prior to or after a meal alters fasting and postprandial blood lactate concentrations in individuals with type 2 diabetes. Obese individuals with type 2 diabetes (N = 12) completed three 2-day trials, including (i) no exercise (NoEx), (ii) resistance exercise prior to dinner (Ex-M), and (iii) resistance exercise beginning at 45 min postdinner (M-Ex). During day 1 of each trial, fasting and postprandial blood lactate concentrations, perceived exertion, and substrate oxidation were measured, and subsequently on day 2 the following morning fasting blood lactate was measured. The premeal lactate incremental area under the curve (iAUC) during Ex-M (109 ± 66 mmol·L -1 ·1.6 h -1 ) was over 100-fold greater (P 0.05). Perceived exertion, substrate oxidation, or fasting blood lactate concentrations the day after testing were not different between trials. Blood lactate concentrations during acute resistance exercise are greater when exercise is performed in the postprandial period. Acute resistance exercise performed the night prior does not alter fasting blood lactate concentrations the following morning.

Tai Chi Chuan (TCC) is a Chinese conditioning exercise and is well known for its slow and graceful movements. Recent investigations have found that TCC is beneficial to cardiorespiratory function, strength, balance, flexibility, microcirculation and psychological profile. The long-term practice of TCC can attenuate the age decline in physical function, and consequently it is a suitable exercise for the middle-aged and elderly individuals. TCC can be prescribed as an alternative exercise programme for selected patients with cardiovascular, orthopaedic, or neurological diseases, and can reduce the risk of falls in elderly individuals. The exercise intensity of TCC depends on training style, posture and duration. Participants can choose to perform a complete set of TCC or selected movements according to their needs. In conclusion, TCC has potential benefits in health promotion, and is appropriate for implementation in the community.

The purpose of this study was to examine whether exercising can positively influence the stereotypes associated with individuals with cancer and, more specifically, have an effect on the impression formation related to warmth and competence. A total of 193 French college students (Mage  = 21.08, SD = 1.44 years; 88 females and 105 males) were randomly assigned to one of the conditions of a 2 (participant sex) × 2 (target health status: cancer vs no information) × 3 (target exercise status: exerciser vs non-exerciser vs no information) experimental design. Results indicated that exercising target with cancer was perceived as the most competent compared with targets with cancer and those without information about cancer. These results suggest that exercising could be an effective way to undermine cancer stereotypes and reduce discrimination against people with cancer. © 2014 John Wiley & Sons A/S.

The purpose of this study was to test the hypothesized association between exercise self-efficacy and exercise behavior, controlling for demographic variables and clinical characteristics, in a sample of individuals with spinal cord injuries. A cross-sectional national survey of 612 community-dwelling adults with spinal cord injury in the United States ranging from 18 to 89 yrs of age was conducted. Sample consisted of 63.1% men with a mean (SD) duration of 15.8 (12.79) yrs postinjury; 86.3% reported using a wheelchair. Self-efficacy was the only independent variable that consistently predicted all four exercise outcomes. Self-efficacy beliefs were significantly related to frequency and intensity of resistance training (R(2) change = 0.08 and 0.03, respectively; P exercise frequency and intensity (R(2) change = 0.01 and 0.03, respectively; P exercise. Self-efficacy beliefs play an important role as predictors of exercise. Variations in exercise intensity along the age continuum have implications for exercise prescription and composition. Future research should replicate findings with objective activity measures.

We determine episodic and high-quantity prescribers' contribution to opioid prescriptions and total morphine milligram equivalents in California, especially among individuals prescribed large amounts of opioids. This was a cross-sectional descriptive analysis of opioid prescribing patterns during an 8-year period using the de-identified Controlled Substance Utilization Review and Evaluation System (CURES) database, the California subsection of the prescription drug monitoring program. We took a 10% random sample of all patients and stratified them by the amount of prescription opioids obtained during their maximal 90-day period. We identified "episodic prescribers" as those whose prescribing pattern included short-acting opioids on greater than 95% of all prescriptions, fewer than or equal to 31 pills on 95% of all prescriptions, only 1 prescription in the database for greater than 90% of all patients to whom they gave opioids, fewer than 6 prescriptions in the database to greater than 99% of patients given opioids, and fewer than 540 prescriptions per year. We identified top 5% prescribers by their morphine milligram equivalents per day in the database. We examined the relationship between patient opioid prescriptions and provider type, with the primary analysis performed on the patient cohort who received only short-acting opioids in an attempt to avoid guideline-concordant palliative, oncologic, and addiction care, and a secondary analysis performed on all patients. Among patients with short-acting opioid only, episodic prescribers (14.6% of 173,000 prescribers) wrote at least one prescription to 25% of 2.7 million individuals but were responsible for less than 9% of the 10.5 million opioid prescriptions and less than 3% of the 3.9 billion morphine milligram equivalents in our sample. Among individuals with high morphine milligram equivalents use, episodic prescribers were responsible for 2.8% of prescriptions and 0.6% of total morphine milligram equivalents

Full Text Available The present study aims to emphasize the role of cardiopulmonary exercise training (CPET in evaluation and recommendation of individualized exercise training in patients with a metabolic syndrome. Methods: We performed a prospective longitudinal study of 9 months. The study group consisted of 28 young patients (21.3±3.1 years old without contraindications to exercise, previously diagnosed with metabolic syndrome according to NCEP-ATPIII criteria. All patients were evaluating at baseline and after 3 months of intervention and at the end of the study (after 9 months. The evaluation consists in performing a CPET on bicycle ergometer in which subjects were monitored in terms of cardiac and respiratory parameters. The CPET results allow us to establish the range of effort intensity in which the patient should exercise in order to burn calories and achieve the maximum fat oxidation rate. All patients benefit from an intensive interval exercise training programme, supervised and guided by a physical therapist. Exercise training consisted in 50 minutes sessions, 3 times per week, at intensive endurance training zone (in the range of anaerobic threshold, completed by 1 minute interval in the range between anaerobic threshold (AT and respiratory compensation point (RCP, for every 5 minutes of training. Results: After 9 months of intervention we noticed an improvement of abdominal obesity (waist circumference decreased from 98.98±10.14 cm to 89.54±12.32 cm, p<0.001, physical fitness (V’O2peak increased from 1.83±0.33 l/min to 2.13±0.4 l/min, p<0.001 and endurance (Oxygen uptake in the range of anaerobic treshold increase from 1.27±0.27 l/min to 1.55±0.31 l/min, p<0.001. Conclusions: Cardiopulmonary exercise testing together with training zones determinations is a useful tool for assessing the exercise capacity and drawing up individual workouts. Active and closely monitored intervention by individualized exercise training programmes leads to

This study aimed to characterize the immediate and extended effect of acute exercise on hunger, energy intake, and circulating acylated ghrelin concentrations using a large data set of homogenous experimental trials and to describe the variation in responses between individuals. Data from 17 of our group's experimental crossover trials were aggregated yielding a total sample of 192 young, healthy males. In these studies, single bouts of moderate to high-intensity aerobic exercise (69% ± 5% V˙O2 peak; mean ± SD) were completed with detailed participant assessments occurring during and for several hours postexercise. Mean hunger ratings were determined during (n = 178) and after (n = 118) exercise from visual analog scales completed at 30-min intervals, whereas ad libitum energy intake was measured within the first hour after exercise (n = 60) and at multiple meals (n = 128) during the remainder of trials. Venous concentrations of acylated ghrelin were determined at strategic time points during (n = 118) and after (n = 89) exercise. At group level, exercise transiently suppressed hunger (P hunger and circulating acylated ghrelin concentrations with notable diversity between individuals. Care must be taken to distinguish true interindividual variation from random differences within normal limits.

Near infrared reactance (NIR) is used to measure body fat percentage (BF%), but there is little data on its use in non-obese, regularly exercising individuals. Therefore, this study aimed to examine the limits of agreement between NIR compared to dual x-ray absorptiometry (DXA) for the measurement of BF% in 2 cohorts of regularly exercising individuals. BF% was measured using DXA and NIR in a regular exercising (≥3 sessions/week), healthy active cohort (HA; n=57), and in a regularly exercising and resistance trained (≥2 sessions/week) cohort (RT; n=59). The RT cohort had lower BF% than the HA cohort (15.3±5.5% and 25.8±7.1%, Pexercising individuals. However, the rather broad LOA of NIR need to be considered when using NIR to screen for overweight and obesity, or measure and track changes in body composition. © Georg Thieme Verlag KG Stuttgart · New York.

Full Text Available Aerobic exercise is used in treating hypertension. Eventhough physiotherapists are the first choice in presenting exercise treatment, few are available to do so in primary health clinics. Nurses arepatients’ first contact and may be able to fulfil this role. Nurses’knowledge and attitude towards exercise as a treatment method for hypertensive patients was determined. This descriptive study included all nurses (n=67 working in 23 Bloemfontein clinics. Forty-three nursescompleted structured questionnaires that determined their knowledge of exercise as a treatment method. All nurses prescribed medication forhypertensive patients. Most nurses prescribed weight control (72.1%, diet control (76.7%, patient education (74.4%, and life-style modification (72.1%. Most (83.7% nurses were aware of exercise as a treatment method for hypertension. Only seven nurses, prescribing a brisk walk, recommended the correct type of exercise. The nurses’attitude towards exercise as a treatment method was determined using focus group interviews (n=16. Nurses reflected a positive attitude towards exercise with 198 positive responses. Nurses could express more than one opinion, all of which were recorded. Twenty responses reflected little or no knowledge, and four responses reflected an unsure/neutral attitude towards exercise. Ten responses reflected disinterest in prescribing exercise. Nurses do not have adequate knowledge to enable them to confidently prescribe exercise to patients. The need for more information was mentioned and some nurses were willing to present exercise classes. A training program, containing pertinent information, so that nurses can prescribe exercise for hypertension, needs to be developed.

Comparative studies of exercise interventions for people with Parkinson disease (PD) rarely considered how one should deliver the intervention. The objective of this study was to compare the success of exercise when administered by (1) home exercise program, (2) individualized physical therapy, or (3) a group class. We examined if common comorbidities associated with PD impacted success of each intervention. Fifty-eight people (age = 63.9 ± 8 years) with PD participated. People were randomized into (1) home exercise program, (2) individual physical therapy, or (3) group class intervention. All arms were standardized and based on the Agility Boot Camp exercise program for PD, 3 times per week for 4 weeks. The primary outcome measure was the 7-item Physical Performance Test. Other measures of balance, gait, mobility, quality of life, balance confidence, depressions, apathy, self-efficacy and UPDRS-Motor, and activity of daily living scores were included. Only the individual group significantly improved in the Physical Performance Test. The individual exercise showed the most improvements in functional and balance measures, whereas the group class showed the most improvements in gait. The home exercise program improved the least across all outcomes. Several factors effected success, particularly for the home group. An unsupervised, home exercise program is the least effective way to deliver exercise to people with PD, and individual and group exercises have differing benefits. Furthermore, people with PD who also have other comorbidities did better in a program directly supervised by a physical therapist.Video Abstract available for additional insights from the authors (see Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A112).

Behavior can only be understood by identifying the goals to which it is attached. Superordinate-level goals are linked to individuals' values, and may offer insights into how to connect exercise with their core values and increase participation in sustainable ways. A random sample of healthy midlife women (aged 40-60y) was selected to participate in a year-long mixed-method study (n = 226). Superordinate goals were measured inductively and analyzed using grounded theory analysis. Attainment Value and Exercise Participation were quantitatively measured. An ANOVA and pairwise comparisons were conducted to investigate the differences between superordinate exercise goals in attainment value. This study fit a Linear Mixed Model to the data to investigate the fixed effects of superordinate goals on exercise participation, controlling for BMI and social support. Participants mainly exercised to achieve Healthy-Aging, Quality-of-Life, Current-Health, and Appearance/Weight superordinate goals. Despite equally valuing Healthy-Aging, Quality-of-Life, and Current-Health goals, participants with Quality-of-Life goals reported participating in more exercise than those with Current-Health (p marketing, we can glean insights into how we can better market and "sell" exercise. Because immediate payoffs motivate behavior better than distant goals, a more effective "hook" for promoting sustainable participation might be to rebrand exercise as a primary way individuals can enhance the quality of their daily lives. These findings have important implications for how we as a culture, especially those in fitness-related businesses, health promotion, health care, and public health, prescribe and market exercise on individual and population levels.

Do adolescents practise the exercises as prescribed (TUT and repetitions)? Do adolescents accurately...... report the exercises they do in an exercise diary? DESIGN: Observational feasibility study. PARTICIPANTS: Twenty adolescents between 15 and 19 years of age with patellofemoral pain. INTERVENTION: Participants were prescribed three exercise sessions per week (one with and two without supervision) for 6......% of the instructed exercise dosage based on TUT. The exercise dosage reported in the exercise diaries was 2.3 times higher than the TUT data from the electronic system. Pain intensity was successfully collected in 100% of the exercise sets. CONCLUSION: The system was feasible for adolescents with patellofemoral pain...

The health benefits of exercise are well documented, yet annual health care costs related to physical inactivity are well within the billions. Furthermore, individuals with schizophrenia spectrum disorders (SSDs) are more likely to lead sedentary lives, exercise less than the general population, and die prematurely from preventable causes. Previous research examining the effects of exercise on individuals with SSDs has been encouraging yet limited in creating accessible and sustainable interventions. The current pilot study developed and evaluated the impact of Work out by Walking (WOW), a multicomponent group walking intervention on the health of 16 individuals with SSDs. Results indicated improvements in indicators of physical health, activity level, social support, and mental health and a high level of program satisfaction. Future research should examine multicomponent group walking programs for individuals with SSDs in larger samples and with the inclusion of a comparison condition.

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.

The effect of acute exercise, and exercise intensity, on appetite control in obese individuals requires further study. The aim of this study was to compare the effects of acute isocaloric bouts (250 kcal) of high-intensity intermittent cycling (HIIC) and moderate-intensity continuous cycling (MICC) or short-duration HIIC (S-HIIC) (125 kcal) and a resting control condition on the appetite hormone responses, subjective feelings of appetite, energy intake (EI), and food reward in overweight/obese individuals. This study is a randomized crossover study on 12 overweight/obese volunteers. Participants were assigned to the control, MICC, HIIC, and S-HIIC conditions, 1 wk apart, in a counterbalanced order. Exercise was performed 1 h after a standard breakfast. An ad libitum test lunch was served 3 h after breakfast. Fasting/postprandial plasma samples of insulin, acylated ghrelin, polypeptide YY3-36, and glucagon-like peptide 1 and subjective feelings of appetite were measured every 30 min for 3 h. Nutrient and taste preferences were measured at the beginning and end of each condition using the Leeds Food Preference Questionnaire. Insulin levels were significantly reduced, and glucagon-like peptide 1 levels significantly increased during all exercise bouts compared with those during rest. Acylated ghrelin plasma levels were lower in the MICC and HIIC, but not in S-HIIC, compared with those in control. There were no significant differences for polypeptide YY3-36 plasma levels, hunger or fullness ratings, EI, or food reward. Our findings suggest that, in overweight/obese individuals, isocaloric bouts of moderate- or high-intensity exercise lead to a similar appetite response. This strengthens previous findings in normal-weight individuals that acute exercise, even at high intensity, does not induce any known physiological adaptation that would lead to increased EI.

Change in maximal aerobic capacity (VO2pk) in response to exercise training and disuse is highly variable among individuals. Factors that could contribute to the observed variability (lean mass, daily activity, diet, sleep, stress) are not routinely controlled in studies. The NASA bed rest (BR) studies use a highly controlled hospital based model as an analog of spaceflight. In this study, diet, hydration, physical activity and light/dark cycles were precisely controlled and provided the opportunity to investigate individual variability. PURPOSE. Evaluate the contribution of exercise intensity and lean mass on change in VO2pk during 70-d of BR or BR + exercise. METHODS. Subjects completed 70-d of BR alone (CON, N=9) or BR + exercise (EX, N=17). The exercise prescription included 6 d/wk of aerobic exercise at 70 - 100% of max and 3 d/wk of lower body resistance exercise. Subjects were monitored 24 hr/d. VO2pk and lean mass (iDXA) were measured pre and post BR. ANOVA was used to evaluate changes in VO2pk pre to post BR. Subjects were retrospectively divided into high and low responders based on change in VO2pk (CON > 20% loss, n=5; EX >10% loss, n=4, or 5% gain, n=4) to further understand individual variability. RESULTS. VO2pk decreased from pre to post BR in CON (Pexercise intensity. CONCLUSION. Change in VO2pk in response to disuse and exercise was highly variable among individuals, even in this tightly controlled study. Loss in lean mass accounts for a significant degree of variability in the CON; however, training induced gains in VO2pk appear unrelated to lean mass or exercise intensity.

Sarcopenia is a well-known phenomenon in elderly individuals and resistance exercise together with sufficient amino acid (AA) availability has proved to be a counteractive implement. However, the source of AA and supplement timing require further investigation. The objective was to compare muscle...... protein synthesis (MPS) to intakes of whey and caseinate after heavy resistance exercise in healthy elderly individuals, and, furthermore, to compare the timing effect of caseinate intake. Twenty-four elderly men and women (mean ± SEM; 68 ± 1 years) were randomized to one of four groups: caseinate intake...... and caseinate feeding immediately after heavy resistance exercise in elderly individuals, and MPS is similar with caseinate ingestion before and after exercise....

Effects of Acute Endurance Exercise on Plasma Protein Profiles of Endurance-Trained and Untrained Individuals over Time

Directory of Open Access Journals (Sweden)

Marius Schild

2016-01-01

Full Text Available Acute physical exercise and repeated exercise stimuli affect whole-body metabolic and immunologic homeostasis. The aim of this study was to determine plasma protein profiles of trained (EET, n=19 and untrained (SED, n=17 individuals at rest and in response to an acute bout of endurance exercise. Participants completed a bicycle exercise test at an intensity corresponding to 80% of their VO2max. Plasma samples were taken before, directly after, and three hours after exercise and analyzed using multiplex immunoassays. Seventy-eight plasma variables were included in the final analysis. Twenty-nine variables displayed significant acute exercise effects in both groups. Seven proteins differed between groups, without being affected by acute exercise. Among these A2Macro and IL-5 were higher in EET individuals while leptin showed elevated levels in SED individuals. Fifteen variables revealed group and time differences with elevated levels for IL-3, IL-7, IL-10, and TNFR2 in EET individuals. An interaction effect could be observed for nine variables including IL-6, MMP-2, MMP-3, and muscle damage markers. The proteins that differ between groups indicate a long-term exercise effect on plasma protein concentrations. These findings might be of importance in the development of exercise-based strategies in the prevention and therapy of chronic metabolic and inflammatory diseases and for training monitoring.

Sex-related differences in fuel utilization and hormonal response to exercise: implications for individuals with type 1 diabetes.

Science.gov (United States)

Brockman, Nicole K; Yardley, Jane E

2018-06-01

Sex-related differences in metabolic and neuroendocrine response to exercise in individuals without diabetes have been well established. Men and women differ in fuel selection during exercise, in which women rely to a greater extent on fat oxidation, whereas males rely mostly on carbohydrate oxidation for energy production. The difference in fuel selection appears to be mediated by sex-related differences in hormonal (including catecholamines, growth hormone, and estrogen) response to different types and intensities of exercise. In general, men exhibit an amplified counter-regulatory response to exercise, with elevated levels of catecholamines compared with women. However, women exhibit greater sensitivity to the lipolytic action of the catecholamines and deplete less of their glycogen stores than men during exercise, which suggests that women may experience a greater defense in blood glucose control after exercise than men. Conversely, little is known about sex-related differences in response to exercise in individuals with type 1 diabetes (T1D). A single study investigating sex-related differences in response to moderate aerobic exercise in individuals with T1D found sex-related differences in catecholamine response and fuel selection, but changes in blood glucose were not measured. To our knowledge, there are no studies investigating sex-related differences in blood glucose responses to different types and intensities of exercise in individuals with T1D. This review summarizes sex-related differences in exercise responses that could potentially impact blood glucose levels during exercise in individuals with T1D and highlights the need for further research.

Central arterial stiffness is associated with incident hypertension and negative cardiovascular outcomes. Obese individuals have higher central blood pressure (BP) and central arterial stiffness than their normal-weight counterparts, but it is unclear whether obesity also affects hemodynamics and central arterial stiffness after maximal exercise. We evaluated central hemodynamics and arterial stiffness during recovery from acute maximal aerobic exercise in obese and normal-weight individuals. Forty-six normal-weight and twenty-one obese individuals underwent measurements of central BP and central arterial stiffness at rest and 15 and 30 min following acute maximal exercise. Central BP and normalized augmentation index (AIx@75) were derived from radial artery applanation tonometry, and central arterial stiffness was obtained via carotid-femoral pulse wave velocity (cPWV) and corrected for central mean arterial pressure (cPWV/cMAP). Central arterial stiffness increased in obese individuals but decreased in normal-weight individuals following acute maximal exercise, after adjusting for fitness. Obese individuals also exhibited an overall higher central BP ( P  <   0.05), with no exercise effect. The increase in heart rate was greater in obese versus normal-weight individuals following exercise ( P  <   0.05), but there was no group differences or exercise effect for AIx@75 In conclusion, obese (but not normal-weight) individuals increased central arterial stiffness following acute maximal exercise. An assessment of arterial stiffness response to acute exercise may serve as a useful detection tool for subclinical vascular dysfunction. © 2017 The Authors.

Adiposity alters acylated ghrelin concentrations, but it is unknown whether adiposity alters the effect of exercise and feeding on acylated ghrelin responses. Therefore, the purpose of this study was to determine whether adiposity [normal-weight (NW) vs. obese (Ob)] influences the effect of exercise and feeding on acylated ghrelin, hunger, and fullness. Fourteen NW and 14 Ob individuals completed two trials in a randomized counterbalanced fashion, including a prior exercise trial (EX) and a no exercise trial (NoEX). During the EX trial, the participants performed 1 h of treadmill walking (55-60% peak O2 uptake) during the evening, 12 h before a 4-h standardized mixed meal test. Frequent blood samples were taken and analyzed for acylated ghrelin, and a visual analog scale was used to assess perceived hunger and fullness. In NW individuals, EX, compared with NoEX, reduced fasting acylated ghrelin concentrations by 18% (P = 0.03), and, in response to feeding, the change in acylated ghrelin (P = 0.02) was attenuated by 39%, but perceived hunger and fullness were unaltered. In Ob individuals, despite no changes in fasting or postprandial acylated ghrelin concentrations with EX, postprandial fullness was attenuated by 46% compared with NoEX (P = 0.05). In summary, exercise performed the night before a meal suppresses acylated ghrelin concentrations in NW individuals without altering perceived hunger or fullness. In Ob individuals, despite no changes in acylated ghrelin concentrations, EX reduced the fullness response to the test meal. Acylated ghrelin and perceived fullness responses are differently altered by acute aerobic exercise in NW and Ob individuals.

Both sex and aging have been shown to affect physiological responses to exercise. The aim of the present investigation was to determine whether aging impacted the sex-specific nature of physiological responses to exercise commonly noted among young adults. Ten aged men (69.0 ± 1.7 years; mean ± SE) and 10 aged women (71.6 ± 1.3 years) reporting similar levels of habitual physical activity performed a 30-min exercise session at 60-65% of their predetermined peak oxygen uptake. Cardiovascular, thermoregulatory, and metabolic variables were assessed before exercise, at the 15th and 30th min of exercise, and at 5 and 15 min into a passive postexercise recovery period. Variables of interest were statistically analyzed via two-way analysis of variance with repeated measures; significance was set at P physiological variable of interest were identified, but not once was a significant effect of group (i.e., sex) detected. Exercise-induced physiological responses to prolonged, moderate intensity exercise were similar among aged men and aged women. This evidence that the sexually dimorphic nature of physiological responses to exercise is obviated with age should be taken into account when prescribing health-related exercise training programs for older individuals.

This study examined neuromuscular fatigue after high-intensity intermittent exercise in 10 men with mild intellectual disability (ID) in comparison with 10 controls. Both groups performed three maximal voluntary contractions (MVC) of knee extension with 5 min in-between. The highest level achieved was selected as reference MVC. The fatiguing exercise consists of five sets with a maximal number of flexion-extension cycles at 80% of the one maximal repetition (1RM) for the right leg at 90° with 90 s rest interval between sets. The MVC was tested again after the last set. Peak force and electromyography (EMG) signals were measured during the MVC tests. Root Mean Square (RMS) and Median Frequency (MF) were calculated. Neuromuscular efficiency (NME) was calculated as the ratio of peak force to the RMS. Before exercise, individuals with ID had a lower MVC (psport train ID individuals, they should consider this nervous system weakness. Copyright © 2013 Elsevier Ltd. All rights reserved.

Trunk stabilization exercises for healthy individuals

2014-01-01

Full Text Available DOI: http://dx.doi.org/10.5007/1980-0037.2014v16n2p200   The aim of this study was to analyze the trunk muscular response during different variations of some of the most popular stabilization exercises: front-bridge, back-bridge, side-bridge, and bird-dog. Surface electromyography was bilaterally re-corded from rectus abdominis, external and internal oblique and erector spinae during 25 variations of the aforementioned exercises. Compared to the conventional form of the front- and side-bridge, performing these exercises kneeling on a bench or with elbows extended reduced the muscular challenge. Conversely, performing the back-bridge with elbows extended elicited higher muscular activation than the conventional exercise. While bridge exercises with double leg support produced the highest activation levels in those muscles that counteracted gravity, single leg support while bridging increased the activation of the trunk rotators, especially internal oblique. The highest activation levels were found in three exercises: sagittal walkout in a front-bridge position, rolling from right side-bridge into front-bridge position, and side-bridge with single leg support on a BOSUTMbalance trainer. Although the exercises performed on unstable surfaces usu-ally enhanced the muscle activation, performing the exercises on the BOSUTMbalance trainer did not always increase the trunk muscle activity. Overall, this information may be useful to guide fitness instructors and clinicians when establishing stabilization exercise progressions for the trunk musculature.

Patients considering or engaged in exercise as treatment may expect or experience transient increases in joint pain, causing fear of exercise and influencing compliance. This study investigated the pain trajectory during an 8-week neuromuscular exercise (NEMEX) program together with acute exercise-induced pain flares in persons with knee or hip pain. Individuals above 35 years self-reporting persistent knee or hip pain for the past 3 months were offered 8 weeks of supervised NEMEX, performed in groups twice weekly. The program consisted of 11 exercises focusing on joint stability and neuromuscular control. Participants self-reported joint pain on a 0-10 numerical rating scale (NRS) at baseline and 8-weeks follow-up. NRS pain ratings were also collected before and immediately after every attended exercise session. Joint pain was reduced from baseline (NRS 3.6; 95% CI 3.2-4.1) to 8-weeks follow-up (2.6; 95% CI 2.1-3.1), (P neuromuscular exercise. Copyright © 2015 Osteoarthritis Research Society International.

No tool exists to measure self-efficacy for overcoming lymphedema-related exercise barriers in individuals with cancer-related lymphedema. However, an existing scale measures confidence to overcome general exercise barriers in cancer survivors. Therefore, the purpose of this study was to develop, validate and assess the reliability of a subscale, to be used in conjunction with the general barriers scale, for determining exercise barriers self-efficacy in individuals facing lymphedema-related exercise barriers. A lymphedema-specific exercise barriers self-efficacy subscale was developed and validated using a cohort of 106 cancer survivors with cancer-related lymphedema, from Brisbane, Australia. An initial ten-item lymphedema-specific barrier subscale was developed and tested, with participant feedback and principal components analysis results used to guide development of the final version. Validity and test-retest reliability analyses were conducted on the final subscale. The final lymphedema-specific subscale contained five items. Principal components analysis revealed these items loaded highly (>0.75) on a separate factor when tested with a well-established nine-item general barriers scale. The final five-item subscale demonstrated good construct and criterion validity, high internal consistency (Cronbach's alpha = 0.93) and test-retest reliability (ICC = 0.67, p exercise barriers self-efficacy in individuals with cancer-related lymphedema. This scale can be used in conjunction with an existing general exercise barriers scale to enhance exercise adherence in this understudied patient group.

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

Directory of Open Access Journals (Sweden)

Elena Barbieri

2015-01-01

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.

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.

Physical activity is important to manage symptom of fibromyalgia (FM); however, individuals with FM typically experience augmented muscle pain during exercise. This study examined the effects of caffeinated chewing gum on exercise-induced muscle pain in individuals with FM. This study was conducted with a double-blind, placebo-controlled, cross-over design. Twenty-three patients with FM completed a caffeine condition where they consumed a caffeinated chewing gum that contains 100mg of caffeine, and a placebo condition where they consumed a non-caffeinated chewing gum. They completed isometric handgrip exercise at 25% of their maximal strength for 3 min, and muscle pain rating (MPR) was recorded every 30s during exercise. Clinical pain severity was assessed in each condition using a pain questionnaire. The order of the two conditions was randomly determined. MPR increased during exercise, but caffeinated chewing gum did not attenuate the increase in MPR compared to placebo gum. Clinical pain severity was generally associated with the average MPR and the caffeine effects on MPR, calculated as difference in the average MPR between the two conditions. The results suggest that more symptomatic individuals with FM may experience greater exercise-induced muscle pain, but benefit more from caffeinated chewing gum to reduce exercise-induced muscle pain.

Alcohol use disorders (AUD) are a major public health concern due to their association with several acute and chronic health conditions. Exercise training offers a myriad of physical and mental health benefits, and may be a promising adjunct intervention for those in AUD treatment. The purpose of this study was to explore the possible role of exercise training as a treatment strategy by examining the attitudes, beliefs, and preferences of individuals entering residential AUD treatment. Surveys were administered to eligible individuals with AUD within 2days of intake to one of two residential treatment centers. The survey asked respondents about their attitudes, beliefs, and preferences towards exercise training as a part of their residential treatment. Respondents were in favor of receiving exercise counseling as part of their treatment (70.6%), in a face-to-face format (90.0%), and from an exercise counselor at the treatment center (55.5%). The top reported benefits included: improved health, feeling good about oneself, and feeling more confident. The most commonly reported barriers to exercise training included transportation issues, lack of motivation, knowledge, and proper equipment, and cost. Our study supports previous work in individuals with substance abuse disorders and suggests that exercise training would be widely accepted as a part of residential treatment for AUD. This study also identified several strategies that can be used to individualize exercise training programs to better meet the needs of AUD patients and maximize their participation in future interventions.

Full Text Available In lean individuals, acute aerobic exercise is reported to transiently suppress sensations of appetite, suppress blood concentrations of acylated ghrelin (AG, and increase glucagon-like peptide-1 (GLP-1 and peptide-YY (PYY. Findings in overweight/obese individuals have yet to be synthesised. In this systematic review and meta-analysis, we quantified the effects that acute exercise has on AG and total PYY and GLP-1 in overweight/obese individuals. The potential for body mass index (BMI to act as a moderator for AG was also explored. Six published studies (73 participants, 78% male, mean BMI: 30.6 kg·m−2 met the inclusion criteria. Standardised mean differences (SMDs and standard errors were extracted for AG and total PYY and GLP-1 concentrations in control and exercise trials and synthesised using a random effects meta-analysis model. BMI was the predictor in metaregression for AG. Exercise moderately suppressed AG area-under-the-curve concentrations (pooled SMD: −0.34, 95% CI: −0.53 to −0.15. The magnitude of this reduction was greater for higher mean BMIs (pooled metaregression slope: −0.04 SMD/kg·m−2 (95% CI: −0.07 to 0.00. Trivial SMDs were obtained for total PYY (0.10, 95% CI: −0.13 to 0.31 and GLP-1 (−0.03, 95% CI: −0.18 to 0.13. This indicates that exercise in overweight/obese individuals moderately alters AG in a direction that could be associated with decreased hunger and energy intake. This trial is registered with PROSPERO: CRD42014006265.

There is limited knowledge of the key determinants of antimicrobial prescribing behavior (APB) in hospitals. An understanding of these determinants is required for the successful design, adoption, and implementation of quality improvement interventions in antimicrobial stewardship programs. Qualitative semistructured interviews were conducted with doctors (n = 10), pharmacists (n = 10), and nurses and midwives (n = 19) in 4 hospitals in London. Interviews were conducted until thematic saturation was reached. Thematic analysis was applied to the data to identify the key determinants of antimicrobial prescribing behaviors. The APB of healthcare professionals is governed by a set of cultural rules. Antimicrobial prescribing is performed in an environment where the behavior of clinical leaders or seniors influences practice of junior doctors. Senior doctors consider themselves exempt from following policy and practice within a culture of perceived autonomous decision making that relies more on personal knowledge and experience than formal policy. Prescribers identify with the clinical groups in which they work and adjust their APB according to the prevailing practice within these groups. A culture of "noninterference" in the antimicrobial prescribing practice of peers prevents intervention into prescribing of colleagues. These sets of cultural rules demonstrate the existence of a "prescribing etiquette," which dominates the APB of healthcare professionals. Prescribing etiquette creates an environment in which professional hierarchy and clinical groups act as key determinants of APB. To influence the antimicrobial prescribing of individual healthcare professionals, interventions need to address prescribing etiquette and use clinical leadership within existing clinical groups to influence practice.

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.

Acute resistance exercise can reduce the blood pressure (BP) of hypertensive subjects. The aim of this study was to evaluate the effect of different volumes of acute low-intensity resistance exercise over the magnitude and the extent of BP changes in treated hypertensive elderly individuals. Sixteen participants (7 men, 9 women), with mean age of 68 ± 5 years, performed 3 independent randomized sessions: Control (C: 40 minutes of rest), Exercise 1 (E1: 20 minutes, 1 lap in the circuit), and Exercise 2 (E2: 40 minutes, 2 laps in the circuit) with the intensity of 40% of 1 repetition maximum. Blood pressure was measured before (during 20 minutes) and after each session (every 5 minutes during 60 minutes) using both a mercury sphygmomanometer and a semiautomatic device (Omrom-HEM-431). After that, 24-hour ambulatory blood pressure monitoring was performed (Dyna-MAPA). Blood pressure decreased during the first 60 minutes (systolic: p exercise sessions. Only the highest volume session promoted a reduction of mean systolic 24-hour BP and awake BP (p exercise, with higher diastolic BP during sleep (p exercise sessions in a circuit with different volumes reduced BP during the first 60 minutes after exercise in elderly individuals with treated hypertension. However, only the highest volume promoted a reduction of mean 24-hour and awake systolic BP.

Low back pain during pregnancy is common and associated with sick leave. Studies suggest that exercise may reduce low back pain during pregnancy. Before carrying out a randomised controlled trail with individual water exercise as intervention a qualitative feasibility study was done. To explore women's views and experiences of the acceptability and benefits of and possible barriers to the standardised individual unsupervised water exercise intervention. Eleven women were interviewed after participating in a water exercise intervention. Content analysis was used. Four main categories emerged: motivation to participate, attitudes towards the exercise programme, perception of benefits, and acceptability of supportive components. The women had a desire to stay physically active during pregnancy and found water exercise a suitable, type of exercise to perform during pregnancy. The intervention was experienced to have benefits on both their physical health and their mental well-being. Crowded swimming pools were perceived as the greatest barrier. It is feasible to perform a RCT using the described intervention. The intervention was accepted by the participants because it supported their desire to be physically active during pregnancy. The main barrier was crowded swimming pools and this issue must be addressed in a future RCT. Copyright © 2014 Elsevier B.V. All rights reserved.

The Effects of Exercise on Natriuretic Peptides in Individuals without Heart Failure

Hidetaka Hamasaki

Full Text Available Cardiac natriuretic peptides (NPs play an important role in the regulation of energy expenditure in skeletal muscle and adipose tissue. A systematic review on the effects of exercise on NPs in patients with heart failure reported that aerobic and resistance training reduced NPs; however, the effects of exercise on NPs and the underlying mechanism of exercise-induced NP secretion in subjects without heart failure remain unknown. In athletes and young, healthy subjects, the NP concentration at rest is not elevated, but strenuous endurance exercise significantly increases NPs. The exercise-induced increase in NPs may be caused by transient myocardial wall stress, cardiomyocyte metabolic changes, or neuroendocrinological response, which may have cytoprotective and growth-regulating effects on the heart. On the other hand, in elderly, overweight/obese subjects, and patients with hypertension, NP concentrations also increase during exercise; however, NP secretion may be more susceptible to cardiac stress compared to young, healthy individuals. Recent studies have shown that NPs are associated with thermogenesis in fat tissue and oxidative capacity in skeletal muscles. NPs may also have a protective role for skeletal muscle in humans, although further studies are warranted to elucidate the physiological mechanism of exercise-induced NP secretion.

Background The standard clinical approach for reducing cardiovascular disease risk due to dyslipidemia is to prescribe changes in diet and physical activity. The purpose of the current study was to determine if, across a range of dietary patterns, there were variable lipoprotein responses to an aerobic exercise training intervention. Methods Subjects were participants in the Studies of a Targeted Risk Reduction Intervention through Defined Exercise (STRRIDE I), a supervised exercise program in sedentary, overweight subjects randomized to 6 months of inactivity or one of 3 aerobic exercise programs. To characterize diet patterns observed during the study, we calculated a modified z-score that included intakes of total fat, saturated fat, trans fatty acids, cholesterol, omega-3 fatty acids and fiber as compared to the 2006 AHA diet recommendations. Linear models were used to evaluate relationships between diet patterns and exercise effects on lipoproteins/lipids. Results Independent of diet, exercise had beneficial effects on LDL-cholesterol particle number, LDL-cholesterol size, HDL-cholesterol, HDL-cholesterol size, and triglycerides (Pdiet pattern that closely adhered to AHA recommendations was not related to changes in these or any other serum lipids or lipoproteins in any of the exercise groups. Conclusions We found that even in sedentary individuals whose habitual diets vary in the extent of adherence to AHA dietary recommendations, a rigorous, supervised exercise intervention can achieve significant beneficial lipid effects.

Oxygen consumption (VO2 and energy expenditure were measured in 33 men/women (BMI≥27 kg/m2 who completed two 30 min walking bouts: (1 self-selected walking pace on an indoor track and (2 prescribed exercise pace (60% VO2 peak on a treadmill. The data revealed that (1 the prescribed intensity was 6% higher than the self-selected pace and elicited a higher energy expenditure (<0.05 than the self-selected pace (+83 kJ; (2 overweight subjects walked at a slightly lower percentage of VO2 peak than the obese subjects (<0.05; (3 men walked at a lower percentage of VO2 peak than the women (<0.05. In conclusion when asked to walk at a moderate intensity, overweight/obese individuals tended to select a lower workload in the “moderate intensity” range which could be maintained for 30 min; however, a higher intensity which would be more cardioprotective could not be maintained for 30 min by most individuals.

Full text: Objectives: To evaluate the normal individual cardiac function in the different imaging phases post-exercise and rest by GSPECT. Methods: 46 normal individuals underwent exercise/rest GSPECT using 99mTc-MIBI by 2- day program. Sequential imaging was started 15, 35 and 120 minutes after exercise and rest imaging was performed the following day. The left ventricular EF and EDV, ESV values were calculated with the Cedars-Sinai program. Results: The EF values of post- exercise at 15, 35, and 120m was 64.48±7.43%, 65.02±7.66%, and 60.98±7.28% respectively, and the rest EF value was 61.46±7.23%. The post exercise EF at 15m and 35m was higher than EF at post- exercise 120m and rest, but there is a significant difference only between post exercise 35m and rest (P< 0.05), and all post exercise EF did not increase at least 5% from EF at-rest. The EDV and ESV values did not have statistically significant differences at 15, 35,120m post-exercise and rest. The heart rate at 15,35m post- exercise was higher significantly than at rest. Conclusions: The different imaging phases after exercise with 99mTc-MIBI GSPECT affects LVEF in normal individuals, the 35m post- exercise EF is highest. (author)

Stress is associated with the maintenance of eating disorders and exercise behaviors. However, it is unclear how stress is associated with exercise and vice-versa among individuals with higher levels of eating disorder symptoms in daily life. The current study tested the moderating effect of eating disorder symptoms on the relationships between (1) daily stress and later exercise behavior and (2) daily exercise behavior and later stress. Female college students [N = 129, mean age = 19.19 (SD = 1.40)] completed the Eating Disorder Inventory-2. Participants then completed measures of stress and exercise four times daily across seven days using an automated telephone ecological momentary assessment system. Data were analyzed using multilevel models. Drive for thinness, bulimic symptoms, and body dissatisfaction significantly moderated the relationship between daily stress and later exercise (ps = .01-.05), such that higher daily stress predicted higher later exercise only in individuals who were low (but not average or high) in drive for thinness, bulimic symptoms, and body dissatisfaction symptoms. Stress is associated with exercise differentially depending on individuals' eating disorder symptoms. Our findings suggest that only individuals with lower levels of eating disorder symptoms exercise when stressed. © 2017 Wiley Periodicals, Inc.

ABSTRACT Purpose: The purpose of this article is to apply theoretical frameworks to adherence behaviour and to guide the development of an intervention to increase adherence to prescribed home programmes. Summary of Key Points: Delivering an effective intervention requires establishing one that is evidence based and of adequate dosage. Two-thirds of patients who receive home exercise prescriptions do not adhere to their home programme, which may contribute to their physiotherapy's being ineffective. The mediating concepts of self-efficacy (SE) and outcome expectations (OE) are common to the five relevant theories used to explain adherence to exercise: the health belief model, protection motivation theory, theory of reasoned action, theory of planned behaviour, and social cognitive theory. Conclusion/Recommendations: Few intervention studies with any theoretical underpinning have examined adherence to exercise. Even fewer have been designed to affect and measure change in the theoretical mediators of SE and OE in patient populations. Physiotherapists must consider increasing adherence as a component of effective physiotherapy. Ongoing research is needed to increase our understanding of adherence to prescribed home programmes and to design interventions to affect theoretical mediators for increasing adherence.

The purpose of this study was to investigate the response of arterial stiffness in individuals with a sedentary lifestyle at 4 weeks after terminating a 2-week aerobic exercise session. Arterial stiffness was evaluated in 38 participants before starting and after completing a prescribed aerobic exercise program and also at 4 weeks after returning back to their sedentary lifestyle. Parameters regarding arterial compliance, distensibility, wall stress, and the elastic modulus were estimated from the information gained from sonography on the dimensions of carotid and femoral arteries and a sphygmomanometer on the pulse pressure. Primary outcomes included whether short-term aerobic exercise reduced the heart rate, arterial pressure, and intima-media thickness and improved vascular biomechanics in physically inactive but otherwise healthy individuals. The benefits gained in arterial compliance and distensibility deteriorated with termination of exercise, but diastolic wall stress and the elastic modulus improved further. In individuals with sedentary lifestyles, short-term aerobic exercise has strong four-week residual benefits on diastolic wall stress and the elastic modulus, but the effects appear to be negligible on arterial stiffness and distensibility. © 2016 by the American Institute of Ultrasound in Medicine.

Full Text Available Traditionally, physiotherapy for cystic fibrosis focused mainly on airway clearance (clearing mucus from the lungs. This still makes up a large part of daily treatment, but the role of the physiotherapist in cystic fibrosis has expanded to include daily exercise, inhalation therapy, posture awareness and, for some, the management of urinary incontinence. The purpose of this study is to demonstrate the necessity and the efficiency of various methods of chest physiotherapy and individualized unsupervised exercise program, in the improvement of body composition and physical performance. This study included 12 children with cystic fibrosis, with ages between 8-13 years. Each subject was evaluated in terms of body composition, effort capacity and lower body muscular performance, at the beginning of the study and after 12 months.The intervention consisted in classic respiratory clearance and physiotherapy techniques (5 times a week and an individualized unsupervised exercise program (3 times a week. After 12 months we noticed a significant improvement of the measured parameters: body weight increased from 32.25±5.5 to 33.53±5.4 kg (p <0.001, skeletal muscle mass increased from a mean of 16.04±4.1 to 17.01±4.2 (p<0.001, the fitness score, increased from a mean of 71±3.8 points to73±3.8, (p<0.001 and power and force also registered positive evolutions (from 19.3±2.68 to 21.65±2.4 W/kg and respectively 19.68±2.689 to 20.81±2.98 N/kg.The association between physiotherapy procedures and an individualized (after a proper clinical assessment unsupervised exercise program, proved to be an effective, relatively simple and accessible (regardless of social class intervention.

Despite its general benefits for health, exercise complicates the maintenance of stable blood glucose concentrations in individuals with type 1 diabetes. The aim of the current study was to examine changes in food intake, insulin administration, and 24-h glycemic control in response to consecutive days with prolonged walking exercise (∼8h daily) in individuals with type 1 diabetes. Ten individuals with type 1 diabetes participating in the worlds' largest walking event were recruited for this observational study. Simultaneous measurements of 24-h glycemic control (continuous glucose monitoring), insulin administration and food intake were performed during a non-walking day (control) and during three subsequent days with prolonged walking exercise (daily distance 40 or 50km). Despite an increase in daily energy (31±18%; p10 mmol/L) and hypoglycemia (blood glucose 0.05 for all variables). The prolonged walking exercise was associated with a modest increase in glycemic variability compared with the control day (pexercise allows for profound reductions in daily insulin administration in persons with type 1 diabetes, despite large increments in energy and carbohydrate intake. When taking such adjustments into account, prolonged moderate-intensity exercise does not necessarily impair 24-h glycemic control. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

CONDITIONS GOVERNING THE EXERCISE OF COMMERCIAL ACTIVITIES BY PROFESSIONALS

Full Text Available The Romanian Constitution establishes that market economy in Romania is based on private property and is developed under the law of supply and demand. As such, the State has the obligation to ensure freedom of trade, protection of fair competition and to create an appropriate framework for the use of all factors of production. The Constitution also provides that the choice of profession should be free, and that the exercise of this freedom may be limited "only by law", with regard to the right to work. The operative principle in relation to commercial activities is the freedom of trade, according to which anyone is free to exercise a commercial profession, provided they respect the limitations and the special conditions prescribed by law. As regards the conditions governing the exercise of commercial activities, the law establishes certain conditions on the capacity of individuals to conduct economic activities, also establishing certain incapacities, as well as incompatibilities, forfeitures and bans on making trade. The law sets specific conditions regarding the capacity of individuals to conduct commercial professional activities, but it also establishes some incapacities to provide shelter from adverse consequences to some persons.

This study used functional magnetic resonance imaging (fMRI) to compare individual muscle use in exercises aimed at preventing hamstring injuries. Thirty-six professional soccer players were randomized into 4 groups, each performing either Nordic hamstring, flywheel leg curl, Russian belt or conic-pulley exercise. MRIs were performed before and immediately after a bout of 4 sets of 8 repetitions. Pre-post exercise differences in contrast shift (T2) were analyzed for the long (BFLh) and short head (BFSh) of biceps femoris, semitendinosus (ST), semimembranosus (SM) and gracilis (GR) muscles. Flywheel leg curl increased (Phamstring, GR (39%), ST (16%) and BFSh (14%) showed increased T2 (Phamstring and GR muscle use. However, no single exercise executed was able to increase T2 of all hamstring and synergist muscles analyzed. It is therefore suggested that multiple exercises must be carried out to bring in, and fully activate all knee flexors and hip extensors. © Georg Thieme Verlag KG Stuttgart · New York.

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.

Many families have problems adhering to home exercise programs (HEP) for children with developmental disabilities. However, parental participation in HEP is known to have a positive effect on child-related outcome variables, as well as on parental functioning. This study examined whether the different behaviours of health professionals, and the behaviour and social characteristics of parents determine rates of parental adherence to both the frequency per week, and duration per session, of HEP for children with developmental disabilities attending paediatric services in early intervention centres. In this study, developmental disabilities include those caused by developmental delay or specific health conditions such as cerebral palsy, congenital illness, or others. Survey. Eighteen early intervention centers. Parents of children with developmental disabilities receiving HEP. A self-reported questionnaire was used to examine: whether frequency and duration of weekly exercise sessions was prescribed by physiotherapists; whether the child had received the HEP according to what was prescribed; and items related to the individual, social support, illnesses and the involvement of the health professional. Multiple logistic regression analyses examined their relative relevance. In this study 219 parents participated. The rate of adherence to the prescribed frequency and duration of the HEP was similar (61.4-57.2%). The probability of adherence to both components increased for parents who had a low perception of the existence of barriers for integrating the exercises into their daily routine (OR=2.62 and 4.83). Furthermore, other cognitive factors of parents had a variable influence. The involvement of the professional had a significant impact regarding the frequency of the HEP. Professional involvement increased the probability of exercises being followed accurately by adopting strategies such as: providing information about the progress and evolution of the exercises (OR=3

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.

Certain components of physical exercise, such as the type, intensity and frequency of exercise, are likely to influence participation among working adults with non-specific LBP, but the value and relative importance of these components remain unknown. The study's aim was to examine such specific components and their influence on individual preferences for exercise for secondary prevention of non-specific LBP among working adults.In a discrete choice experiment, working individuals with non-specific LBP answered a web-based questionnaire. Each respondent was given ten pairs of hypothetical exercise programs and asked to choose one option from each pair. The choices comprised six attributes of exercise (i.e., type of training, design, intensity, frequency, proximity and incentives, each with either three or four levels. A conditional logit regression that reflected the random utility model was used to analyze the responses.The final study population consisted of 112 participants. The participants' preferred exercise option was aerobic (i.e., cardiovascular rather than strength training, group exercise with trainer supervision, rather than individual or unsupervised exercise. They also preferred high intensity exercise performed at least once or twice per week. The most popular types of incentive were exercise during working hours and a wellness allowance rather than coupons for sports goods. The results show that the relative value of some attribute levels differed between young adults (age ≤ 44 years and older adults (age ≥ 45 years in terms of the level of trainer supervision required, exercise intensity, travel time to exercise location and financial incentives. For active study participants, exercise frequency (i.e., twice per week, 1.15; CI: 0.25; 2.06 influenced choice of exercise. For individuals with more than one child, travel time (i.e., 20 minutes, -0.55; CI: 0

Adolescents with patellofemoral pain (PFP) do not comply with their exercise prescription, performing too few and too fast repetitions, compromising recovery. We investigated if real-time feedback on contraction time would improve the ability of adolescents with PFP to perform exercises as prescribed. A randomized, controlled, participant-blinded, superiority trial with a 6-wk intervention of three weekly sessions of three elastic band exercises was undertaken. Forty 15- to 19-yr-old adolescents with PFP were randomized to real-time BandCizer™-iPad feedback on contraction time or not by a physiotherapist. The primary outcome was the mean deviation from the prescribed contraction time of 8 s per repetition. Secondary outcomes included isometric hip and knee strength, Kujala Patellofemoral Scale, and Global Rating of Change. The mean deviation from prescribed 8 s per repetition contraction time was 1.5 ± 0.5 s for the feedback group, compared with 4.3 ± 1.0 s for the control group (mean difference: 2.7 s (95% confidence interval = 2.2-3.2, P feedback group received 35.4% of the prescribed exercise dose whereas the control group received 20.3%. Isometric hip and knee strength increased significantly more in the feedback group compared with controls (mean difference = 1.35 N·kg, 95% confidence interval = 0.02-2.68, P = 0.047). There were no significant differences in Kujala Patellofemoral Scale and Global Rating of Change between groups, but the study was not powered for this. Real-time feedback on contraction time resulted in the ability to perform exercises closer to the prescribed dose and also induced larger strength gains.

To examine the incidence of prescribing errors in a main public hospital in Pakistan and to assess the impact of introducing electronic prescribing system on the reduction of their incidence. Medication errors are persistent in today's healthcare system. The impact of electronic prescribing on reducing errors has not been tested in developing world. Prospective review of medication and discharge medication charts before and after the introduction of an electronic inpatient record and prescribing system. Inpatient records (n = 3300) and 1100 discharge medication sheets were reviewed for prescribing errors before and after the installation of electronic prescribing system in 11 wards. Medications (13,328 and 14,064) were prescribed for inpatients, among which 3008 and 1147 prescribing errors were identified, giving an overall error rate of 22·6% and 8·2% throughout paper-based and electronic prescribing, respectively. Medications (2480 and 2790) were prescribed for discharge patients, among which 418 and 123 errors were detected, giving an overall error rate of 16·9% and 4·4% during paper-based and electronic prescribing, respectively. Electronic prescribing has a significant effect on the reduction of prescribing errors. Prescribing errors are commonplace in Pakistan public hospitals. The study evaluated the impact of introducing electronic inpatient records and electronic prescribing in the reduction of prescribing errors in a public hospital in Pakistan. © 2011 Blackwell Publishing Ltd.

Full Text Available Background: A sedentary life style is a type of life style with no or irregular physical activity. It is a leading cause for reduced cardio - respiratory fitness and physical activity. The most of the employees working as computer personnel’s for more than five hours in a day is leading to altered physical activity and fitness. To study the effect of aerobic exercise programme on the cardio - respiratory fitness in computer using sedentary individuals. Methods: As per the inclusion criteria the thirty subjects were selected for the study, all the selected subjects were given aerobic protocol for 12 weeks. Pre and post therapeutic outcome measures were assessed for Body Mass Index was calculated using weight (kg/ height (m2. Waist- hip ratio was measured using inch tape in centimeters, pre and post therapeutic values of Body Mass Index, Waist Hip Ratio, VO2 peak were assessed. Results: According to the data analysis, a significant difference was found between the pre and post test values of Body Mass Index, Waist- hip ratio and Vo2peak in both experimental and control groups (p<0.05, but comparatively more significant changes were found in the experimental rather than the control group(p<0.05. Conclusion: Aerobic exercise had significant influence in computer using sedentary individuals. There was a significant change in physical factors like body mass index, waist-hip ratio, and functional factors like vo2peak. Hence, it is concluded that 12weeks of aerobic exercises is effective in improving cardio vascular factors computer using sedentary individuals.

compared with the afternoon or evening. Even fewer researchers have adequately separated the influences of waking from sleep, adopting an upright posture and physical exertion per se on these pathophysiological responses at different times of day. In healthy individuals, exercise is generally perceived as more difficult and functional performance is decreased in the morning hours. These observations have been confirmed for patients with heart disease in only one small study. It has also not been confirmed, using an adequately powered study involving cardiac patients, that the responses of heart rate and oxygen consumption (VO(2)) to a set bout of exercise show the highest reactivity in the afternoon and evening, which is the case with healthy individuals. Confirmation of this circadian variation would be important, since it would mean that exercise might be prescribed at too high an intensity in the morning if heart rate or VO(2) responses are employed as markers of exercise load. We conclude that there is some parallelism between the diurnal changes in physical activity and those in the pathophysiological mechanisms associated with acute cardiac events. Nevertheless, more studies are needed to ascertain whether the responses of endothelial function, fibrinolysis and blood pressure to a set exercise regimen differ according to time of day. The results of epidemiological studies suggest that morning exercise is just as safe as afternoon exercise for cardiac patients enrolled in a supervised rehabilitation programme. Nevertheless, it is unclear whether time of day alters the risk of a cardiac event occurring during spontaneous physical activity performed by individuals with established risk factors for heart disease.

Kingsley, JD, Mayo, X, Tai, YL, and Fennell, C. Arterial stiffness and autonomic modulation after free-weight resistance exercises in resistance trained individuals. J Strength Cond Res 30(12): 3373-3380, 2016-We investigated the effects of an acute bout of free-weight, whole-body resistance exercise consisting of the squat, bench press, and deadlift on arterial stiffness and cardiac autonomic modulation in 16 (aged 23 ± 3 years; mean ± SD) resistance-trained individuals. Arterial stiffness, autonomic modulation, and baroreflex sensitivity (BRS) were assessed at rest and after 3 sets of 10 repetitions at 75% 1-repetition maximum on each exercise with 2 minutes of rest between sets and exercises. Arterial stiffness was analyzed using carotid-femoral pulse wave velocity (cf-PWV). Linear heart rate variability (log transformed [ln] absolute and normalized units [nu] of low-frequency [LF] and high-frequency [HF] power) and nonlinear heart rate complexity (Sample Entropy [SampEn], Lempel-Ziv Entropy [LZEn]) were measured to determine autonomic modulation. BRS was measured by the sequence method. A 2 × 2 repeated measures analysis of variance (ANOVA) was used to analyze time (rest, recovery) across condition (acute resistance exercise, control). There were significant increases in cf-PWV (p = 0.05), heart rate (p = 0.0001), normalized LF (LFnu; p = 0.001), and the LF/HF ratio (p = 0.0001). Interactions were also noted for ln HF (p = 0.006), HFnu (p = 0.0001), SampEn (p = 0.001), LZEn (p = 0.005), and BRS (p = 0.0001) such that they significantly decreased during recovery from the resistance exercise compared with rest and the control. There was no effect on ln total power, or ln LF. These data suggest that a bout of resistance exercise using free-weights increases arterial stiffness and reduces vagal activity and BRS in comparison with a control session. Vagal tone may not be fully recovered up to 30 minutes after a resistance exercise bout.

Physicians face the choice of multiple ingredients when prescribing drugs in many therapeutic categories. For conditions with considerable patient heterogeneity in treatment response, customizing treatment to individual patient needs and preferences may improve outcomes. To assess variation in the diversity of antipsychotic prescribing for mental health conditions, a necessary although not sufficient condition for personalizing treatment. To identify patient caseload, physician, and organizational factors associated with the diversity of antipsychotic prescribing. Using 2011 data from Pennsylvania's Medicaid program, IMS Health's HCOSTM database, and the AMA Masterfile, we identified 764 psychiatrists who prescribed antipsychotics to 10 patients. We constructed three physician-level measures of diversity/concentration of antipsychotic prescribing: number of ingredients prescribed, share of prescriptions for most preferred ingredient, and Herfindahl-Hirschman index (HHI). We used multiple membership linear mixed models to examine patient caseload, physician, and healthcare organizational predictors of physician concentration of antipsychotic prescribing. There was substantial variability in antipsychotic prescribing concentration among psychiatrists, with number of ingredients ranging from 2-17, share for most preferred ingredient from 16%-85%, and HHI from 1,088-7,270. On average, psychiatrist prescribing behavior was relatively diversified; however, 11% of psychiatrists wrote an average of 55% of their prescriptions for their most preferred ingredient. Female prescribers and those with smaller shares of disabled or serious mental illness patients had more concentrated prescribing behavior on average. Antipsychotic prescribing by individual psychiatrists in a large state Medicaid program varied substantially across psychiatrists. Our findings illustrate the importance of understanding physicians' prescribing behavior and indicate that even among specialties

The history of “Exercise Is Medicine” in ancient civilizations

Science.gov (United States)

2014-01-01

In 2007, the American College of Sports Medicine, with endorsement from the American Medical Association and the Office of the Surgeon General, launched a global initiative to mobilize physicians, healthcare professionals and providers, and educators to promote exercise in their practice or activities to prevent, reduce, manage, or treat diseases that impact health and the quality of life in humans. Emerging from this initiative, termed Exercise Is Medicine, has been an extensively documented position stand by the American College of Sports Medicine that recommended healthy adults perform 150 min of moderate dynamic exercise per week. The purpose of this article is to demonstrate the foundation for this global initiative and its exercise prescription for health and disease prevention has roots that began in antiquity more than two millennia ago. Individuals and concepts to remember are that Susruta of India was the first “recorded” physician to prescribe moderate daily exercise, Hippocrates of Greece was the first “recorded” physician to provide a written exercise prescription for a patient suffering from consumption, and the global influence of Galen from Rome combined with his recommendation on the use of exercise for patients in the management of disease prevailed until the 16th century. Historically intertwined with these concepts was exercise being advocated by select physicians to minimize the health problems associated with obesity, diabetes, and inactivity. PMID:25039081

Exercise benefits most, but not all, individuals with type 2 diabetes mellitus (T2DM). The aim of this study was to determine whether a proportion of individuals with T2DM would fail to demonstrate exercise-induced metabolic improvements. We hypothesized that this lack of response would be related to their skeletal muscle transcriptional profile. 42 participants with T2DM from the previously reported HART-D study underwent a 9-month supervised exercise intervention. We performed a principal components analysis to distinguish Responders from Non-Responders (n=9 each) based on: decreases in (1) HbA1c, (2) %fat (3) BMI and (4) increase in skeletal muscle mtDNA. mRNA expression patterns in muscle tissue at baseline were assessed by microarray and qRT-PCR analysis in both groups. Of 186 genes identified by microarray analysis, 70% were up-regulated in Responders and down-regulated in Non-Responders. Several genes involved in substrate metabolism and mitochondrial biogenesis were significantly different (fold-change>1.5, pexercise response in metabolic outcomes, thus allowing exercise interventions to be targeted to these individuals and aid in the identification of novel approaches to treat Non-Responders in the future.

Sarcopenia is a well-known phenomenon in elderly individuals and resistance exercise together with sufficient amino acid (AA) availability has proved to be a counteractive implement. However, the source of AA and supplement timing require further investigation. The objective was to compare muscle...... protein synthesis (MPS) to intakes of whey and caseinate after heavy resistance exercise in healthy elderly individuals, and, furthermore, to compare the timing effect of caseinate intake. Twenty-four elderly men and women (mean ± SEM; 68 ± 1 years) were randomized to one of four groups: caseinate intake...

Research suggests that pharmaceutical marketing influences prescribing and may cause cognitive dissonance for prescribers. This work has primarily been with physicians and physician-trainees. Questions remain regarding why prescribers continue to meet with pharmaceutical representatives (PRs). To describe the reasons that prescribers from various health professions continue to interact with PRs despite growing evidence of the influence of these interactions. Multi-disciplinary focus groups with 61 participants held in practice settings and at society meetings. Most prescribers participating in our focus groups believe that overall PR interactions are beneficial to patient care and practice health. They either trust the information from PRs or feel that they are equipped to evaluate it independently. Despite acknowledgement of study findings to the contrary, prescribers state that they are able to effectively manage PR interactions such that their own prescribing is not adversely impacted. Prescribers describe few specific strategies or policies for these interactions, and report that policies are not consistently implemented with all members of a clinic or institution. Some prescribers perceive an inherent contradiction between academic centers and national societies receiving money from pharmaceutical companies, and then recommending restriction at the level of the individual prescriber. Prescribers with different training backgrounds present a few novel reasons for these meetings. Despite evidence that PR detailing influences prescribing, providers from several health professions continue to believe that PR interactions improve patient care, and that they can adequately evaluate and filter information presented to them by PRs. Focus group comments suggest that cultural change is necessary to break the norms that exist in many settings. Applying policies consistently, considering non-physician members of the healthcare team, working with trainees, restructuring

Obesity is a low-grade chronic inflammation condition, and macrophages, and possibly monocytes, are involved in the pathological outcomes of obesity. Physical exercise is a low-cost strategy to prevent and treat obesity, probably because of its anti-inflammatory action. We evaluated the percentage of CD16(-) and CD16(+) monocyte subsets in obese insulin-resistant individuals and the effect of an exercise bout on the percentage of these cells. Twenty-seven volunteers were divided into three experimental groups: lean insulin sensitive, obese insulin sensitive and obese insulin resistant. Venous blood samples collected before and 1 h after an aerobic exercise session on a cycle ergometer were used for determination of monocyte subsets by flow cytometry. Insulin-resistant obese individuals have a higher percentage of CD16(+) monocytes (14.8 ± 2.4%) than the lean group (10.0 ± 1.3%). A positive correlation of the percentage of CD16(+) monocytes with body mass index and fasting plasma insulin levels was found. One bout of moderate exercise reduced the percentage of CD16(+) monocytes by 10% in all the groups evaluated. Also, the absolute monocyte count, as well as all other leukocyte populations, in lean and obese individuals, increased after exercise. This fact may partially account for the observed reduction in the percentage of CD16(+) cells in response to exercise. Insulin-resistant, but not insulin-sensitive obese individuals, have an increased percentage of CD16(+) monocytes that can be slightly modulated by a single bout of moderate aerobic exercise. These findings may be clinically relevant to the population studied, considering the involvement of CD16(+) monocytes in the pathophysiology of obesity. Copyright © 2016 John Wiley & Sons, Ltd. Obesity is now considered to be an inflammatory condition associated with many pathological consequences, including insulin resistance. It is proposed that insulin resistance contributes to the aggravation of the

The purpose of this perspective is (1) to incorporate recent psychological health behaviour change (HBC) theories into exercise therapeutic programmes, and (2) to introduce the International Classification of Functioning (ICF)-based concept of a behavioural exercise therapy (BET). Relevant personal modifiable factors of physical activity (PA) were identified based on three recent psychological HBC theories. Following the principles of intervention mapping, a matrix of proximal programme objectives specifies desirable parameter values for each personal factor. As a result of analysing reviews on behavioural techniques and intervention programmes of the German rehabilitation setting, we identified exercise-related techniques that impact the personal determinants. Finally, the techniques were integrated into an ICF-based BET concept. Individuals' attitudes, skills, emotions, beliefs and knowledge are important personal factors of PA behaviour. BET systematically addresses these personal factors by a systematic combination of adequate exercise contents with related behavioural techniques. The presented 28 intervention techniques serve as a theory-driven "tool box" for designing complex BET programmes to promote PA. The current paper highlights the usefulness of theory-based integrative research in the field of exercise therapy, offers explicit methods and contents for physical therapists to promote PA behaviour, and introduces the ICF-based conceptual idea of a BET. Implications for Rehabilitation Irrespective of the clients' indication, therapeutic exercise programmes should incorporate effective, theory-based approaches to promote physical activity. Central determinants of physical activity behaviour are a number of personal factors: individuals' attitudes, skills, emotions, beliefs and knowledge. Clinicians implementing exercise therapy should set it within a wider theoretical framework including the personal factors that influence physical activity. To increase

Tolerance to exercise intensity modulates pleasure when exercising in music: The upsides of acoustic energy for High Tolerant individuals.

Full Text Available Moderate physical activity can be experienced by some as pleasurable and by others as discouraging. This may be why many people lack sufficient motivation to participate in the recommended 150 minutes of moderately intense exercise per week. In the present study, we assessed how pleasure and enjoyment were modulated differently by one's tolerance to self-paced physical activity. Sixty-three healthy individuals were allocated to three independent experimental conditions: a resting condition (watching TV, a cycling in silence condition, and a cycling in music condition. The tolerance threshold was assessed using the PRETIE-Questionnaire. Physical activity consisted in cycling during 30 minutes, at an intensity perceived as "somewhat difficult" on the Ratings of Perceived Exertion Scale. While controlling for self-reported physical activity level, results revealed that for the same perception of exertion and a similar level of enjoyment, the High Tolerance group produced more power output than the Low Tolerance group. There was a positive effect of music for High Tolerant individuals only, with music inducing greater power output and more pleasure. There was an effect of music on heart rate frequency in the Low Tolerant individuals without benefits in power output or pleasure. Our results suggest that for Low Tolerant individuals, energizing environments can interfere with the promised (positive distracting effects of music. Hence, tolerance to physical effort must be taken into account to conceive training sessions that seek to use distracting methods as means to sustain pleasurable exercising over time.

The Exercise Self-Efficacy scale (ESES) is a reliable measure, in the English language, of exercise self-efficacy in individuals with spinal cord injury. The aim of this study was to culturally adjust and validate the Exercise Self-Efficacy scale in the Portuguese language. The Exercise Self-Efficacy scale was applied to 76 subjects, with three-month intervals (three applications in total). The reliability was appraised using the intra-class correlation coefficient and Bland-Altman methods, and the internal consistency was evaluated using Cronbach´s alpha. The Exercise Self-Efficacy scale was correlated with the domains of the Quality of life Questionnaire SF-36 and Functional Independence Measure and tested using the Spearman rho coefficient. The Exercise Self-Efficacy scale-Brazil presented good internal consistency (alpha 1 = 0.856; alpha 2 = 0.855; alpha 3 = 0.822) and high reliability in the test-retest (intra-class correlation coefficient = 0.97). There was a strong correlation between the Exercise Self-Efficacy scale-Brazil and the SF-36 only in the functional capacity domain (rho = 0.708). There were no changes in Exercise Self-Efficacy scale-Brazil scores between the three applications (p = 0.796). The validation of the Exercise Self-Efficacy scale questionnaire permits the assessor to use it reliably in Portuguese speaking countries, since it is the first instrument measuring self-efficacy specifically during exercises in individuals with spinal cord injury. Furthermore, the questionnaire can be used as an instrument to verify the effectiveness of interventions that use exercise as an outcome. The results of the Brazilian version of the Exercise Self-Efficacy scale support its use as a reliable and valid measurement of exercise self-efficacy for this population.

A cross sectional questionnaire survey design was used to collect quantitative and qualitative data from adult members of the Hypermobility Syndromes Association and Ehlers-Danlos Syndrome Support UK. Descriptive and inferential statistics were used to analyse the data. Qualitative data was analysed thematically. 946 questionnaires were returned and analysed. Participants who received exercise advice from a physiotherapist were 1.75 more likely to report high volumes of weekly exercise (odds ratio [OR] = 1.75, 95% confidence interval [CI] = 1.30-2.36, p Ehlers-Danlos syndrome - hypermobility type in this survey. Implications for rehabilitation Exercise is a cornerstone of treatment for Ehlers-Danlos syndrome/Ehlers-Danlos syndrome - hypermobility type. Pain, fatigue and fear of injury are frequently reported barriers to exercise. Advice from physiotherapists may significantly influence exercise behaviour. Physiotherapists with condition specific knowledge and good verbal and non-verbal communication facilitate a positive therapeutic experience.

Abdominal obesity and metabolic syndrome: exercise as medicine?

Paley, Carole A; Johnson, Mark I

2018-01-01

Metabolic syndrome is defined as a cluster of at least three out of five clinical risk factors: abdominal (visceral) obesity, hypertension, elevated serum triglycerides, low serum high-density lipoprotein (HDL) and insulin resistance. It is estimated to affect over 20% of the global adult population. Abdominal (visceral) obesity is thought to be the predominant risk factor for metabolic syndrome and as predictions estimate that 50% of adults will be classified as obese by 2030 it is likely that metabolic syndrome will be a significant problem for health services and a drain on health economies.Evidence shows that regular and consistent exercise reduces abdominal obesity and results in favourable changes in body composition. It has therefore been suggested that exercise is a medicine in its own right and should be prescribed as such. This review provides a summary of the current evidence on the pathophysiology of dysfunctional adipose tissue (adiposopathy). It describes the relationship of adiposopathy to metabolic syndrome and how exercise may mediate these processes, and evaluates current evidence on the clinical efficacy of exercise in the management of abdominal obesity. The review also discusses the type and dose of exercise needed for optimal improvements in health status in relation to the available evidence and considers the difficulty in achieving adherence to exercise programmes. There is moderate evidence supporting the use of programmes of exercise to reverse metabolic syndrome although at present the optimal dose and type of exercise is unknown. The main challenge for health care professionals is how to motivate individuals to participate and adherence to programmes of exercise used prophylactically and as a treatment for metabolic syndrome.

The overall metabolic/energetic stress that occurs during an acute bout of exercise is proposed to be the main driving force for long-term training adaptations. Continuous and high-intensity interval exercise protocols (HIIE) are currently prescribed to acquire the muscular and metabolic benefits of aerobic training. We applied 1 H NMR-based metabonomics to compare the overall metabolic perturbation and activation of individual bioenergetic pathways of three popular aerobic exercises matched for effort/strain. Nine men performed continuous, long-interval (3 min), and short-interval (30 s) bouts of exercise under isoeffort conditions. Blood was collected before and after exercise. The multivariate PCA and OPLS-DA models showed a distinct separation of pre- and postexercise samples in three protocols. The two models did not discriminate the postexercise overall metabolic profiles of the three exercise types. Analysis focused on muscle bioenergetic pathways revealed an extensive upregulation of carbohydrate-lipid metabolism and the TCA cycle in all three protocols; there were only a few differences among protocols in the postexercise abundance of molecules when long-interval bouts were performed. In conclusion, continuous and HIIE exercise protocols, when performed with similar effort/strain, induce comparable global metabolic response/stress despite their marked differences in work-bout intensities. This study highlights the importance of NMR metabonomics in comprehensive monitoring of metabolic consequences of exercise training in the blood of athletes and exercising individuals.

The purpose of this study was to compare the effects of high, moderate and low intensity plyometric exercise on the post-exercise systolic and diastolic blood pressure and heart rate responses. Ten healthy normotensive men (age, 21.1±0.9 years; height, 175.8±6 cm; and body mass, 69.1±13.6 kg) volunteered to participate in this study and were evaluated for three non-consecutive days in depth jump exercise from 20-cm box (low intensity [LI]), 40-cm box (moderate intensity [MI]) and 60-cm box (high intensity [HI]) for 5 sets of 20 repetitions. After each exercise session, systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) were measured every 10 min for a period of 90 min. No significant differences were observed among post-exercise SBP, DBP and HR when the protocols (LI, MI and HI) were compared. The LI and HI protocols showed greater reduction in SBP at 40(th)-70(th) min of post-exercise (~9%), whereas the LI and MI protocols indicated greater reduction in DBP at 10(th)-50(th) min of post exercise (~10%). In addition, the change in the DBP for HI was not significant and the increases in the HR were similar for all intensities. It can be concluded that a plyometric exercise (PE) can reduce SBP and DBP post-exercise and therefore we can say that PE has significant effects for reducing BP and HR or post-exercise hypotension.

The respondents were divided into three groups depending on frequency of MBE practice (never/seldom/often. Measures regarding MBE practice, health behaviors, self-rated health, and illnesses were drawn from the SLOSH questionnaire, while more objective measures of socioeconomic status and education were derived from registry data. In addition, data on purchases of prescription drugs for all respondents were included in the study. These data were obtained from the Swedish Prescribed Drug Register, which contains information about prescription drugs dispensed at Swedish pharmacies. Separate analyses were performed for mental MBE (mindfulness, meditation, relaxation techniques and physical MBE (yoga, Tai Chi, Qi Gong, respectively.A high intensity MBE practice is cross-sectionally related to poor self-assessed health (sleeping problems, pain, depressive symptoms, mental disorders, high levels of stress, and high levels of purchases of psychotropic drugs and analgesics. These cross-sectional relationships are generally stronger for mental MBE than for bodily-directed MBE. More women than men are practicing MBE on a regular basis, and physically active people participate to a greater extent in MBE compared with the physically inactive.Overall, the study shows that frequent participation in mind and body exercises is associated with high levels of purchases of psychotropic drugs and analgesics as well as with poor self-assessed health and high levels of stress. However, since this is a cross-sectional study, it is impossible to establish cause and effect

Nurses working in mental health are well positioned to prescribe exercise to people with mental illness. However, little is known regarding their exercise-prescription practices. We examined the self-reported physical activity and exercise-prescription practices of nurses working in inpatient mental health facilities. Thirty-four nurses completed the Exercise in Mental Illness Questionnaire - Health Practitioner Version. Non-parametric bivariate statistics revealed no relationship between nurses' self-reported physical activity participation and the frequency of exercise prescription for people with mental illness. Exercise-prescription parameters used by nurses are consistent with those recommended for both the general population and for people with mental illness. A substantial number of barriers to effective exercise prescription, including lack of training, systemic issues (such as prioritization and lack of time), and lack of consumer motivation, impact on the prescription of exercise for people with mental illness. Addressing the barriers to exercise prescription could improve the proportion of nurses who routinely prescribe exercise. Collaboration with exercise professionals, such as accredited exercise physiologists or physiotherapists, might improve knowledge of evidence-based exercise-prescription practices for people with mental illness, thereby improving both physical and mental health outcomes for this vulnerable population. © 2015 Australian College of Mental Health Nurses Inc.

Medication errors: prescribing faults and prescription errors.

Velo, Giampaolo P; Minuz, Pietro

1. Medication errors are common in general practice and in hospitals. Both errors in the act of writing (prescription errors) and prescribing faults due to erroneous medical decisions can result in harm to patients. 2. Any step in the prescribing process can generate errors. Slips, lapses, or mistakes are sources of errors, as in unintended omissions in the transcription of drugs. Faults in dose selection, omitted transcription, and poor handwriting are common. 3. Inadequate knowledge or competence and incomplete information about clinical characteristics and previous treatment of individual patients can result in prescribing faults, including the use of potentially inappropriate medications. 4. An unsafe working environment, complex or undefined procedures, and inadequate communication among health-care personnel, particularly between doctors and nurses, have been identified as important underlying factors that contribute to prescription errors and prescribing faults. 5. Active interventions aimed at reducing prescription errors and prescribing faults are strongly recommended. These should be focused on the education and training of prescribers and the use of on-line aids. The complexity of the prescribing procedure should be reduced by introducing automated systems or uniform prescribing charts, in order to avoid transcription and omission errors. Feedback control systems and immediate review of prescriptions, which can be performed with the assistance of a hospital pharmacist, are also helpful. Audits should be performed periodically.

Physical exercise in overweight to obese individuals induces metabolic- and neurotrophic-related structural brain plasticity

Directory of Open Access Journals (Sweden)

2015-07-01

Full Text Available Previous cross-sectional studies on body-weight-related alterations in brain structure revealed profound changes in the gray matter (GM and white matter (WM that resemble findings obtained from individuals with advancing age. This suggests that obesity may lead to structural brain changes that are comparable with brain aging. Here, we asked whether weight-loss-dependent improved metabolic and neurotrophic functioning parallels the reversal of obesity-related alterations in brain structure. To this end we applied magnetic resonance imaging together with voxel-based morphometry and diffusion-tensor imaging in overweight to obese individuals who participated in a fitness course with intensive physical training three days per week over a period of three months. After the fitness course, participants presented, with inter-individual heterogeneity, a reduced body mass index (BMI, reduced serum leptin concentrations, elevated high-density lipoprotein-cholesterol (HDL-C, and alterations of serum brain-derived neurotrophic factor (BDNF concentrations suggesting changes of metabolic and neurotrophic function. Exercise-dependent changes in BMI and serum concentration of BDNF, leptin, and HDL-C were related to an increase in GM density in the left hippocampus, the insular cortex, and the left cerebellar lobule. We also observed exercise-dependent changes of diffusivity parameters in surrounding WM structures as well as in the corpus callosum. These findings suggest that weight-loss due to physical exercise in overweight to obese participants induces profound structural brain plasticity, not primarily of sensorimotor brain regions involved in physical exercise, but of regions previously reported to be structurally affected by an increased body weight and functionally implemented in gustation and cognitive processing.

The aim of the study was to explore the relationship between exercise identity and exercise dependence. We hypothesized that stronger exercise identities would be associated with greater odds of experiencing exercise dependence symptoms. Logistic regression was used to assess the extent of association between exercise identity and the risk of experiencing exercise dependence symptoms. Participants (101) were recruited online via sports clubs and social networking sites and were asked to complete online measures of exercise identity and exercise dependence. The overall model fit was a significant improvement on the baseline model, but only the exercise beliefs factor was significantly associated with the odds of dependence symptoms, with higher scores on the belief scale predicting greater odds of experiencing dependence symptoms. Exercise role identity, in contrast, was not significantly associated with odds of experiencing dependence symptoms. Per cent correct classification was 55.9% for asymptomatic and 88.2% for symptomatic individuals and the overall per cent correct classification was 77.5%. The relation between identity and dependence could represent both a fruitful research avenue and a potential therapeutic target for those experiencing dependence symptoms; although our findings only showed a relationship between one of the two factors of the exercise identity measure and dependence. Longitudinal research is required to examine the relationship between identity and dependence in the context of other variables to better understand why some individuals become exercise dependent whereas others do not. What is already known on this subject? Exercise identity has been identified as an important determinant of exercise behaviour and studies within the exercise identity framework have proven elucidative with respect to the psychological processes that may underpin commitment to exercise. It has separately been established that some individuals may become

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

The mechanisms supporting functional improvement by aerobic exercise following stroke remain incompletely understood. This study investigated how cycling intensity and aerobic fitness influence cerebral blood flow (CBF) following a single exercise session. Thirteen community-living stroke survivors performed 20 min of semi-recumbent cycling at low and moderate intensities (40-50 and 60-70 % of heart rate reserve, respectively) as determined from an exercise stress test. CBF was quantified by arterial spin labeling MRI at baseline, as well as 30 and 50 min post-exercise. An intensity-dependent effect was observed in the right post-central and supramarginal gyri up to 50 min after exercise (uncorrected p Aerobic fitness was directly related to posterior cingulate and thalamic CBF, and inversely related to precuneal CBF at rest (R (2) ≥ 0.75); however, no relationship between fitness and the post-exercise change in CBF was observed. Divergent changes in regional CBF were observed in the right parietal cortex following low- and moderate-intensity exercise, which suggests that intensity of prescribed exercise may be useful in optimizing rehabilitation.

The incorporation of physical activity and exercise represents a clinically important aspect in the management of metabolic syndrome, hypertension, and diabetes. While the benefit of exercise and active lifestyles is well documented for prevention and risk reduction of cardiovascular and stroke outcomes, the detailed regiment and recommendations are less clear. The components of a prescribed physical activity include consideration of activity type, frequency of an activity, activity duration, and intensity of a specific physical movement. The exercise parameters prescribed as part of the management of metabolic syndrome, diabetes, and elevated blood pressure are most often proposed as separate documents while the general recommendations are similar. The evidence is strong such that physical activity and exercise recommendations in disease management guidelines are considered high quality. The general recommendations for both blood pressure and glycemic management include a regiment of physical activity with moderate- to high-intensity exercise of 30-min bouts on multiple days with a desired goal of a total of 150 min of exercise per week. While additional research is needed to identify the specific exercise/activity mode, frequencies for exercise training, intensity levels, and duration of exercise that achieve maximal blood pressure and glycemic lowering, this general recommendation showed a consistent and significant benefit in risk reduction. Similarly, the current available evidence also indicates that aerobic exercise, dynamic resistance exercise, and isometric exercises can lower blood pressure and improve glycemic control.

Older people with dementia are at increased risk of physical decline and falls. Balance and mood are significant predictors of falls in this population. The aim of this study was to determine the effect of a tailored home-based exercise program in community-dwelling older people with dementia. Forty-two participants with mild to moderate dementia were recruited from routine health services. All participants were offered a six-month home-based, carer-enhanced, progressive, and individually tailored exercise program. Physical activity, quality of life, physical, and psychological assessments were administered at the beginning and end of the trial. Of 33 participants (78.6%) who completed the six-month reassessment ten (30%) reported falls and six (18%) multiple falls during the follow-up period. At reassessment, participants had better balance (sway on floor and foam), reduced concern about falls, increased planned physical activity, but worse knee extension strength and no change in depression scores. The average adherence to the prescribed exercise sessions was 45% and 22 participants (52%) were still exercising at trial completion. Those who adhered to ≥70% of prescribed sessions had significantly better balance at reassessment compared with those who adhered to balance, concern about falls, and planned physical activity in community-dwelling older people with dementia. Future research should determine whether exercise interventions are effective in reducing falls and elucidate strategies for enhancing uptake and adherence in this population.

This paper is a report of a study conducted to explore doctor and non-prescribing nurse views about nurse prescribing in the light of their experience in dermatology. The cooperation of healthcare professionals and peers is of key importance in enabling and supporting nurse prescribing. Lack of understanding of and opposition to nurse prescribing are known barriers to its implementation. Given the important role they play, it is necessary to consider how the recent expansion of nurse prescribing rights in England impacts on the views of healthcare professionals. Interviews with 12 doctors and six non-prescribing nurses were conducted in 10 case study sites across England between 2006 and 2007. Participants all worked with nurses who prescribed for patients with dermatological conditions in secondary or primary care. Thematic analysis was conducted on the interview data. Participants were positive about their experiences of nurse prescribing having witnessed benefits from it, but had reservations about nurse prescribing in general. Acceptance was conditional upon the nurses' level of experience, awareness of their own limitations and the context in which they prescribed. Fears that nurses would prescribe beyond their level of competence were expected to reduce as understanding and experience of nurse prescribing increased. Indications are that nurse prescribing can be acceptable to doctors and nurses so long as it operates within recommended parameters. Greater promotion and assessment of standards and criteria are recommended to improve understanding and acceptance of nurse prescribing.

The aim of this study was to measure the validity of the prescriber information recorded in the Danish National Prescription Registry (DNPR). The prescriber information recorded in the pharmacies' electronic dispensing system was considered to represent the prescriber information recorded...... in the DNPR. Further, the problem of validity of the prescriber information pertains only to non-electronic prescriptions, as these are manually entered into the dispensing system. The recorded prescriber information was thus validated against information from a total of 2,000 non-electronic prescriptions...... at five Danish community pharmacies. The validity of the recorded prescriber information was measured at the level of the individual prescriber and the prescriber type, respectively. The proportion of non-electronic prescriptions with incorrect registrations was 22.4% (95% Confidence Interval (CI): 20...

The beneficial effect of exercise training and exercise-based cardiac rehabilitation on symptom-free exercise capacity,cardiovascular and skeletal muscle function, quality of life, general healthy lifestyle, and reduction of depressive symptoms and psychosocial stress is nowadays well recognized. However, it remains largely obscure, which characteristics of physical activity (PA) and exercise training--frequency, intensity, time (duration), type (mode), and volume (dose: intensity x duration) of exercise--are the most effective. The present paper, therefore, will deal with these exercise characteristics in the management of individuals with cardiovascular disease, i.e. coronary artery disease and chronic heart failure patients, but also in patients with congenital or valvular heart disease. Based on the current literature, and if sufficient evidence is available, recommendations from the European Association on Cardiovascular Prevention and Rehabilitation are formulated regarding frequency, intensity, time and type of PA, and safety aspects during exercise inpatients with cardiovascular disease. This paper is the third in a series of three papers, all devoted to the same theme: the importance of the exercise characteristics in the management of cardiovascular health. Part I is directed to the general population and Part II to individuals with cardiovascular risk factors. In general, PA recommendations and exercise training programmes for patients with coronary artery disease or chronic heart failure need to be tailored to the individual's exercise capacity and risk profile, with the aim to reach and maintain the individually highest fitness level possible and to perform endurance exercise training 30–60 min daily (3–5 days per week) in combination with resistance training 2–3 times a week. Because of the frequently reported dose–response relationship between training effect and exercise intensity, one should seek sufficiently high training intensities

Exercise helps individuals with prediabetes or type 2 diabetes (T2D) manage their blood glucose (BG); however, exercise adherence in this population is dismal. In this pilot study we tested the efficacy of a self-monitoring group-based intervention using continuous glucose monitors (CGMs) at increasing exercise adherence in individuals with impaired BG. Thirteen participants with prediabetes or T2D were randomized to an 8-week standard care exercise program (CON condition) (n = 7) or self-monitoring exercise intervention (SM condition) (n = 6). Participants in the SM condition were taught how to self-monitor their exercise and BG, to goal set, and to use CGM to observe how exercise influences BG. We hypothesized that compared with the CON condition, using a real-time CGM would facilitate self-monitoring behavior, resulting in increased exercise adherence. Repeated-measures analysis of variance revealed significant Condition × Time interactions for self-monitoring (P goal setting (P = 0.01), and self-efficacy to self-monitor (P = 0.01), such that the SM condition showed greater increases in these outcomes immediately after the program and at the 1-month follow-up compared with the CON condition. The SM condition had higher program attendance rates (P = 0.03), and a greater proportion of participants reregistered for additional exercise programs (P = 0.048) compared with the CON condition. Participants in both conditions experienced improvements in health-related quality of life, waist circumference, and fitness (P values exercise behavior in individuals living with prediabetes or T2D.

2016-01-01

To explore how the meaning of exercise and other factors interact and influence the exercise behaviour of individuals with Parkinson's disease (PD) enrolled in a 6-month minimally supervised exercise program to prevent falls, regardless of whether they completed the prescribed exercise or not. This qualitative study utilised in-depth semi-structured interviews analysed using grounded theory methodology. Four main themes were constructed from the data: adapting to change and loss, the influence of others, making sense of the exercise experience and hope for a more active future. Participation in the PD-specific physiotherapy program involving group exercise provided an opportunity for participants to reframe their identity of their "active" self. Three new influences on exercise participation were identified and explored: non-motor impairments of apathy and fatigue, the belief in a finite energy quota, and the importance of feedback. A model was developed incorporating the themes and influences to explain decision-making for exercise participation in this group. Complex and interacting issues, including non-motor impairments, need to be considered in order to enhance the development and ongoing implementation of effective exercise programmes for people with PD. Exercise participation can assist individuals to reframe their identity as they are faced with losses associated with Parkinson's disease and ageing. Non-motor impairments of apathy and fatigue may influence exercise participation in people with Parkinson's disease. Particular attention needs to be paid to the provision of feedback in exercise programs for people with Parkinson's disease as it important for their decision-making about continuing exercise.

Howden, Erin J; Coombes, Jeff S; Isbel, Nicole M

2015-11-01

In this review, we summarize recent studies of exercise interventions in chronic kidney disease (CKD), potential benefits, discuss barriers to implementation and make practical recommendations for incorporating exercise training into the care of patients with CKD. Interventions targeting increased fitness and physical activity are effective and may have multiple potential benefits. Recommendations regarding physical activity advice have been incorporated into the recent update of the KDIGO CKD guidelines, which suggest that patients perform 30 min of moderate intensity exercise on most days of the week. Exercise as simple, popular and inexpensive as walking appears to be associated with significant health benefits. More vigorous exercise requires increased supervision but can be safely prescribed to patients with a broad range of comorbidities and may be associated with greater gains in health. Physical activity, cardiorespiratory fitness and muscle function are low in patients with CKD. A sedentary lifestyle has been associated with increased mortality, morbidity and the risk factors that drive progression of both kidney and cardiac disease. There is much to learn about the benefits of different modalities of exercise but the time has come to routinely prescribe exercise interventions as part of standard nephrological care.

The Ecology of Exercise: Mechanisms Underlying Individual Variation in Behavior, Activity, and Performance: An Introduction to Symposium.

Killen, Shaun S; Calsbeek, Ryan; Williams, Tony D

Wild animals often engage in intense physical activity while performing tasks vital for their survival and reproduction associated with foraging, avoiding predators, fighting, providing parental care, and migrating. In this theme issue we consider how viewing these tasks as "exercise"-analogous to that performed by human athletes-may help provide insight into the mechanisms underlying individual variation in these types of behaviors and the importance of physical activity in an ecological context. In this article and throughout this issue, we focus on four key questions relevant to the study of behavioral ecology that may be addressed by studying wild animal behavior from the perspective of exercise physiology: (1) How hard do individual animals work in response to ecological (or evolutionary) demands?; (2) Do lab-based studies of activity provide good models for understanding activity in free-living animals and individual variation in traits?; (3) Can animals work too hard during "routine" activities?; and (4) Can paradigms of "exercise" and "training" be applied to free-living animals? Attempts to address these issues are currently being facilitated by rapid technological developments associated with physiological measurements and the remote tracking of wild animals, to provide mechanistic insights into the behavior of free-ranging animals at spatial and temporal scales that were previously impossible. We further suggest that viewing the behaviors of non-human animals in terms of the physical exercise performed will allow us to fully take advantage of these technological advances, draw from knowledge and conceptual frameworks already in use by human exercise physiologists, and identify key traits that constrain performance and generate variation in performance among individuals. It is our hope that, by highlighting mechanisms of behavior and performance, the articles in this issue will spur on further synergies between physiologists and ecologists, to take

Exercises are important as an adjuvant for managing diabetes but due to fatigue and time constraints, individuals with diabetes may not engage in them. Jumping on a mini-trampoline referred to as rebound exercise is an aerobic activity used for exercise training benefits but only little research is available on its effects in diabetes. The purpose of this study was to determine the effect of mini-trampoline rebound exercise on insulin resistance, lipid profile and central obesity in type 2 diabetics. Sixty non-insulin dependent type 2 diabetics (median age: 39.0 years, median body mass index: 25.2 kg/m2) recruited using convenience sampling were randomized to a rebound exercise group (N.=30) or a control group (N.=30). The control group read health magazines or watched television while the rebound exercise group jumped on a mini-trampoline at moderate intensity for 30 minutes three times per week for 12 weeks. Postrebound exercise, significant improvements in insulin resistance, lipid profile and waist circumference were noted when compared to the control (Ptrampoline rebound exercise is beneficial for individuals with type 2 diabetes and can serve as a useful exercise approach in the management of cardiovascular risk in diabetes.

Performing regular exercise is known to manifest a number of health benefits that mainly relate to cardiovascular and muscular adaptations to allow for greater oxygen extraction and utilization. There is increasing evidence that nutrient intake can affect the adaptive response to a single exercise bout, and that protein feeding is important to facilitate this process. Thus, the exercise-nutrient interaction may potentially lead to a greater response to training. The role of post-exercise protein ingestion in enhancing the effects of running-based endurance exercise training relative to energy-matched carbohydrate intervention remains to be established. Additionally, the influence of immediate versus overnight protein ingestion in mediating these training effects is currently unknown. The current protocol aims to establish whether post-exercise nutrient intake and timing would influence the magnitude of improvements during a prescribed endurance training program. The project involves two phases with each involving two treatment arms applied in a randomized investigator-participant double-blind parallel group design. For each treatment, participants will be required to undergo six weeks of running-based endurance training. Immediately post-exercise, participants will be prescribed solutions providing 0.4 grams per kilogram of body mass (g · kg(-1)) of whey protein hydrolysate plus 0.4 g · kg(-1) sucrose, relative to an isocaloric sucrose control (0.8 g · kg(-1); Phase I). In Phase II, identical protein supplements will be provided (0.4 + 0.4 g · kg(-1) · h(-1) of whey protein hydrolysate and sucrose, respectively), with the timing of ingestion manipulated to compare immediate versus overnight recovery feedings. Anthropometric, expired gas, venous blood and muscle biopsy samples will be obtained at baseline and following the six-week training period. By investigating the role of nutrition in enhancing the effects of endurance exercise training, we will provide

Older adults represent the fastest-growing age demographic of the population. Physiological changes associated with primary aging and concurrent chronic disease adversely impact functional capacity, health outcomes, and quality of life. For these reasons, there is a national emphasis for healthcare providers to improve the health, function, and quality of life of older adults to preserve independent living and psychological well-being. The benefits of regular physical activity or exercise with regard to aging and disease are indisputable, yet many clinicians do not prescribe exercise to older adults. This reluctance may be attributable to a lack of knowledge regarding appropriate exercise prescription for older adults in light of the potential risks and benefits of various doses and types of exercise. In addition, clinicians and patients may have concerns about potential health considerations relevant to older adults such as comprehensive pre-exercise screening and exercise-drug interactions. In light of this, the following review presents (1) guidelines for exercise prescription in older adults and modification of these guidelines for patients with the most common age-associated comorbidities; (2) recommendations for pre-exercise screening prior to initiating an exercise program in older adults; (3) considerations for older adults on one or more medications; and (4) common barriers to adopting and maintaining exercise in an older population. Our goal is to provide a framework that clinicians can follow when prescribing exercise in older adults while considering the unique characteristics and concerns present in this population.

Many accounts of social influences on exercise participation describe how people compare their behaviors to those of others. We develop and test a novel hypothesis, the exercise rank hypothesis, of how this comparison can occur. The exercise rank hypothesis, derived from evolutionary theory and the decision by sampling model of judgment, suggests that individuals' perceptions of the health benefits of exercise are influenced by how individuals believe the amount of exercise ranks in comparison with other people's amounts of exercise. Study 1 demonstrated that individuals' perceptions of the health benefits of their own current exercise amounts were as predicted by the exercise rank hypothesis. Study 2 demonstrated that the perceptions of the health benefits of an amount of exercise can be manipulated by experimentally changing the ranked position of the amount within a comparison context. The discussion focuses on how social norm-based interventions could benefit from using rank information.

Full Text Available The purpose of this review was to investigate what type of exercises can potentially prevent osteoporosis (OP and its associated fractures in high-risk populations. MEDLINE was searched for work relevant to various types of exercises used to prevent osteoporotic fractures in high-risk population, from the year 1995 onwards. Twelve articles were identified, and, from them, four were deemed suitable to the objective. The studies reviewed show that various types of exercise are effective and safe in preventing the onset of OP. For example, high-intensity progressive resistance training (HiPRT has been shown to increase vertebral height and femoral neck bone mineral density (BMD, in addition to improving functional performance. Additional studies reviewed suggested that bone reabsorption levels may be positively impacted by low-impact exercise, such as walking. This review provides insight into the effectiveness of various types of exercise to combat and possibly prevent OP for high-risk individuals, which include postmenstrual Caucasian females, people with multiple comorbidities, individuals who smoke or consume alcohol, and the frail elderly population. The prevention of OP should reduce both the social (emotional and economic burdens faced by patients, caregivers, and health-care systems. Moving forward, research that identifies and bridges pharmaceutical treatment and exercise should be conducted, in addition to the comparison of passive versus active forms of exercise to determine which treatment best prevents OP in high-risk populations.

Full Text Available Abstract Background The aim of the present study was to describe the use of prescribed and non prescribed medicines in a non-institutionalised population older than 15 years of an urban area during the year 2000, in terms of age and gender, social class, employment status and type of Primary Health Care. Methods Cross-sectional study. Information came from the 2000 Barcelona Health Interview Survey. The indicators used were the prevalence of use of prescribed and non-prescribed medicines in the two weeks prior to the interview. Descriptive analyses, bivariate and multivariate logistic regression analyses were carried out. Results More women than men took medicines (75.8% vs. 60% respectively. The prevalence of use of prescribed medicines increased with age while the prevalence of non-prescribed use decreased. These age differences are smaller among those with poor perceived health. In terms of social class, a higher percentage of men with good health in the more advantaged classes took non-prescribed medicines compared with disadvantaged classes (38.7% vs 31.8%. In contrast, among the group with poor health, more people from the more advantaged classes took prescribed medicines, compared with disadvantaged classes (51.4% vs 33.3%. A higher proportion of people who were either retired, unemployed or students, with good health, used prescribed medicines. Conclusion This study shows that beside health needs, there are social determinants affecting medicine consumption in the city of Barcelona.

To determine the effects of acute caffeine ingestion on glycaemia during moderate to vigorous intensity aerobic exercise and in recovery in individuals with Type 1 diabetes. A total of 13 patients with Type 1 diabetes [eight women, five men: mean ± sd age 25.9 ± 8.8 years, BMI 71.9 ± 11.0 kg, maximal oxygen consumption 46.6 ± 12.7 ml/kg/min, body fat 19.9 ± 7.2%, duration of diabetes 14.4 ± 10.1 years and HbA1c 55 ± 8 mmol/mol (7.4 ± 0.8%)] were recruited. Participants ingested capsules that contained gelatin or pure caffeine (6.0 mg/kg body mass) and performed afternoon exercise for 45 min at 60% maximal oxygen consumption on two separate visits with only circulating basal insulin levels. The main finding was that a single caffeine dose attenuates the drop in glycaemia by 1.8 ± 2.8 mmol/l compared with placebo intake during exercise (P=0.056). Continuous glucose monitoring data, however, showed that caffeine was associated with elevated glycaemia at bedtime after exercise, compared with placebo, but lower glucose concentrations in the early morning the next day. Caffeine intake should be considered as another strategy that may modestly attenuate hypoglycaemia in individuals with Type 1 diabetes during exercise, but should be taken with precautionary measures as it may increase the risk of late-onset hypoglycaemia. © 2015 Diabetes UK.

[Purpose] To verify the effects of individual and group exercise programs on pain, balance, mobility and perceived benefits of rheumatoid arthritis patients (RA) with pain and foot deformities. [Subjects and Methods] Thirty patients with RA pain and foot deformity were allocated into two groups: G1: individual exercise program and G2: group exercise program. The variables analyzed were Numerical Rating Scale (NRS) for pain, Berg Balance Scale (BBS) for balance, Timed Up & Go Test (TUG) and Functional Reach (FR) for mobility, and Foot Health Status Questionnaire (FHSQ-Br) for perceived benefits. Both exercise programs consisted of functional rehabilitation exercises and self-care guidance aimed at reducing pain and improving balance and mobility. Intragroup comparisons of variables between A1 (pre-intervention) and A2 (post-intervention) were performed. [Results] Patients in both groups were similar in A1 (pre-intervention) in all the variables analyzed. Comparison between A1 and A2 for each variable showed improvement for G1 in the NRS, BBS, FR, TUG and in four out of ten domains of FHSQ-Br. G2 showed improvement in the NRS, BBS and eight out of ten domains of FHSQ-Br. [Conclusion] Both individual and group programs revealed benefits for patients with RA, however, group exercise programs showed better perception of benefits.

Gibson, OR, Willmott, AGB, James, CA, Hayes, M, and Maxwell, NS. Power relative to body mass best predicts change in core temperature during exercise-heat stress. J Strength Cond Res 31(2): 403-414, 2017-Controlling internal temperature is crucial when prescribing exercise-heat stress, particularly during interventions designed to induce thermoregulatory adaptations. This study aimed to determine the relationship between the rate of rectal temperature (Trec) increase, and various methods for prescribing exercise-heat stress, to identify the most efficient method of prescribing isothermic heat acclimation (HA) training. Thirty-five men cycled in hot conditions (40° C, 39% R.H.) for 29 ± 2 minutes. Subjects exercised at 60 ± 9% V[Combining Dot Above]O2peak, with methods for prescribing exercise retrospectively observed for each participant. Pearson product moment correlations were calculated for each prescriptive variable against the rate of change in Trec (° C·h), with stepwise multiple regressions performed on statistically significant variables (p ≤ 0.05). Linear regression identified the predicted intensity required to increase Trec by 1.0-2.0° C between 20- and 45-minute periods and the duration taken to increase Trec by 1.5° C in response to incremental intensities to guide prescription. Significant (p ≤ 0.05) relationships with the rate of change in Trec were observed for prescriptions based on relative power (W·kg; r = 0.764), power (%Powermax; r = 0.679), rating of perceived exertion (RPE) (r = 0.577), V[Combining Dot Above]O2 (%V[Combining Dot Above]O2peak; r = 0.562), heart rate (HR) (%HRmax; r = 0.534), and thermal sensation (r = 0.311). Stepwise multiple regressions observed relative power and RPE as variables to improve the model (r = 0.791), with no improvement after inclusion of any anthropometric variable. Prescription of exercise under heat stress using power (W·kg or %Powermax) has the strongest relationship with the rate of change in

In mental healthcare, one area of major concern identified by health information systems is variability in antipsychotic prescribing. While most studies have investigated patient- and prescriber-related factors as possible reasons for such variability, no studies have investigated facility-level characteristics. The present study ascertained whether staffing level is associated with antipsychotic prescribing in community mental healthcare. A cross-sectional analysis of data extracted from the Italian national mental health information system was carried out. For each Italian region, it collects data on the availability and use of mental health facilities. The rate of individuals exposed to antipsychotic drugs was tested for evidence of association with the rate of mental health staff availability by means of univariate and multivariate analyses. In Italy there were on average nearly 60 mental health professionals per 100,000 inhabitants, with wide regional variations (range 21 to 100). The average rate of individuals prescribed antipsychotic drugs was 2.33%, with wide regional variations (1.04% to 4.01%). Univariate analysis showed that the rate of individuals prescribed antipsychotic drugs was inversely associated with the rate of mental health professionals available in Italian regions (Kendall's tau -0.438, p = 0.006), with lower rates of antipsychotic prescriptions in regions with higher rates of mental health professionals. After adjustment for possible confounders, the total availability of mental health professionals was still inversely associated with the rate of individuals exposed to antipsychotic drugs. The evidence that staffing level was inversely associated with antipsychotic prescribing indicates that any actions aimed at decreasing variability in antipsychotic prescribing need to take into account aspects related to the organization of the mental health system.

Sugars, exercise and health.

There is a direct link between a variety of addictions and mood states to which exercise could be relieving. Sugar addiction has been recently counted as another binge/compulsive/addictive eating behavior, differently induced, leading to a high-significant health problem. Regularly exercising at moderate intensity has been shown to efficiently and positively impact upon physiological imbalances caused by several morbid conditions, including affective disorders. Even in a wider set of physchiatric diseases, physical exercise has been prescribed as a complementary therapeutic strategy. A comprehensive literature search was carried out in the Cochrane Library and MEDLINE databases (search terms: sugar addiction, food craving, exercise therapy, training, physical fitness, physical activity, rehabilitation and aerobic). Seeking high-sugar diets, also in a reward- or craving-addiction fashion, can generate drastic metabolic derangements, often interpolated with affective disorders, for which exercise may represent a valuable, universal, non-pharmachological barrier. More research in humans is needed to confirm potential exercise-mechanisms that may break the bond between sugar over-consumption and affective disorders. The purpose of this review is to address the importance of physical exercise in reversing the gloomy scenario of unhealthy diets and sedentary lifestyles in our modern society.

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.

Full Text Available Introduction: Addressing pain is a crucial aspect of emergency medicine. Prescription opioids are commonly prescribed for moderate to severe pain in the emergency department (ED; unfortunately, prescribing practices are variable. High variability of opioid prescribing decisions suggests a lack of consensus and an opportunity to improve care. This quality improvement (QI initiative aimed to reduce variability in ED opioid analgesic prescribing. Methods: We evaluated the impact of a three-part QI initiative on ED opioid prescribing by physicians at seven sites. Stage 1: Retrospective baseline period (nine months. Stage 2: Physicians were informed that opioid prescribing information would be prospectively collected and feedback on their prescribing and that of the group would be shared at the end of the stage (three months. Stage 3: After physicians received their individual opioid prescribing data with blinded comparison to the group means (from Stage 2 they were informed that individual prescribing data would be unblinded and shared with the group after three months. The primary outcome was variability of the standard error of the mean and standard deviation of the opioid prescribing rate (defined as number of patients discharged with an opioid divided by total number of discharges for each provider. Secondary observations included mean quantity of pills per opioid prescription, and overall frequency of opioid prescribing. Results: The study group included 47 physicians with 149,884 ED patient encounters. The variability in prescribing decreased through each stage of the initiative as represented by the distributions for the opioid prescribing rate: Stage 1 mean 20%; Stage 2 mean 13% (46% reduction, p<0.01, and Stage 3 mean 8% (60% reduction, p<0.01. The mean quantity of pills prescribed per prescription was 16 pills in Stage 1, 14 pills in Stage 2 (18% reduction, p<0.01, and 13 pills in Stage 3 (18% reduction, p<0.01. The group mean

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.

The purpose of this pilot study was to investigate the effectiveness of a mixed-reality (MR) exercise environment on engagement and enjoyment levels of individuals with spinal cord injury (SCI) and intellectual and developmental disabilities (IDD). Six people participated in this cross-sectional, observational pilot study involving one MR exercise trial. The augmented reality environment was based on a first-person perspective video of a scenic biking/walking trail in Colorado. Males and females (mean age, 43.3 ± 13.7 years) were recruited from a research database for their participation in previous clinical studies. Of the 6 participants, 2 had SCI, 2 had IDD, and 2 were without disability. The primary outcome measurement of this pilot study was the self-reported engagement and enjoyment level of each participant after the exercise trial. All participants reported increased levels of engagement, enjoyment, and immersion involving the MR exercise environment as well as positive feedback recommending this type of exercise approach to peers with similar disabilities. All the participants reported higher than normal levels of enjoyment and 66.7% reported higher than normal levels of being on a real trail. Participants' feedback suggested that the MR environment could be entertaining, motivating, and engaging for users with disabilities, resulting in a foundation for further development of this technology for use in individuals with cognitive and physical disabilities.

[Purpose] We investigated the effects of individual strengthening exercises for the stabilization muscles on the nutation torque of the sacroiliac joint in a sedentary worker with nonspecific sacroiliac joint pain. [Subject] A 36-year-old female complained of pain in the sacroiliac joints. [Methods] The subject performed individual strengthening exercises for the stabilization muscles for nutation torque of the sacroiliac joint for 3 weeks. Pain-provocation tests and visual analog scale (VAS) scores were evaluated before and after the exercises. [Results] After performing the individual strengthening exercises for the erector spinae, rectus abdominis, and biceps femoris muscles for 3 weeks, the subject displayed no pain in the pain provocation tests, and the VAS score was 2/10. [Conclusion] The individual strengthening exercises for the stabilization muscles of the sacroiliac joint performed in the present study appear to be effective for sedentary workers with sacroiliac joint pain.

Eduardo Iglesias-Gutiérrez

Full Text Available Considering that hyperhomocysteinemia is an independent risk factor for cardiovascular disease, the purpose of this study was to determine the kinetics of serum homocysteine (tHcy and the vitamins involved in its metabolism (folates, B(12, and B(6 in response to acute exercise at different intensities. Eight sedentary males (18-27 yr took part in the study. Subjects were required to complete two isocaloric (400 kcal acute exercise trials on separate occasions at 40% (low intensity, LI and 80% VO(2peak (high intensity, HI. Blood samples were drawn at different points before (pre4 and pre0 h, during (exer10, exer20, exer30, exer45, and exer60 min, and after exercise (post0, post3, and post19 h. Dietary, genetic, and lifestyle factors were controlled. Maximum tHcy occurred during exercise, both at LI (8.6 (8.0-10.1 µmol/L, 9.3% increase from pre0 and HI (9.4 (8.2-10.6 µmol/L, 25.7% increase from pre0, coinciding with an accumulated energy expenditure independent of the exercise intensity. From this point onwards tHcy declined until the cessation of exercise and continued descending. At post19, tHcy was not different from pre-exercise values. No values of hyperhomocysteinemia were observed at any sampling point and intensity. In conclusion, acute exercise in sedentary individuals, even at HI, shows no negative effect on tHcy when at least 400 kcal are spent during exercise and the nutritional status for folate, B(12, and B(6 is adequate, since no hyperhomocysteinemia has been observed and basal concentrations were recovered in less than 24 h. This could be relevant for further informing healthy exercise recommendations.

Glucose-6-phospate dehydrogenase (G6PD) deficient cells are sensitive to oxidative damage leading to the formation of microparticles (MPs). Therefore, we examined the concentration of MPs and changes in the antioxidant balance after an acute strenuous exercise (SEx) and moderate-intensity exercise (MEx). Eighteen healthy females (18-24 years) with G6PD normal and eighteen age-matched females with G6PD Viangchan (871G>A) were tested by running on a treadmill at their maximal oxygen uptake for SEx and at 75% of their maximal heart rate for MEx. It was found that SEx triggered the release of total microparticles (TTMPs) above baseline levels and remained significantly higher 45 minutes after the exercise in G6PD normal individuals. However, SEx-induced increase in TTMPs was significantly higher in G6PD Viangchan as compared to G6PD normal. In contrast, MEx did not to alter the release of TTMPs in both G6PD normal and Viangchan. Moreover, TTMPs concentrations were inversely correlated with G6PD activity (r =-0.82, P stress compared with G6PD normal.

Computational opioid prescribing: a novel application of clinical pharmacokinetics.

Linares, Oscar A; Linares, Annemarie L

2011-01-01

We implemented a pharmacokinetics-based mathematical modeling technique using algebra to assist prescribers with point-of-care opioid dosing. We call this technique computational opioid prescribing (COP). Because population pharmacokinetic parameter values are needed to estimate drug dosing regimen designs for individual patients using COP, and those values are not readily available to prescribers because they exist scattered in the vast pharmacology literature, we estimated the population pharmacokinetic parameter values for 12 commonly prescribed opioids from various sources using the bootstrap resampling technique. Our results show that opioid dosing regimen design, evaluation, and modification is feasible using COP. We conclude that COP is a new technique for the quantitative assessment of opioid dosing regimen design evaluation and adjustment, which may help prescribers to manage acute and chronic pain at the point-of-care. Potential benefits include opioid dose optimization and minimization of adverse opioid drug events, leading to potential improvement in patient treatment outcomes and safety.

To determine the frequency of physiotherapist-administered aerobic exercise testing/training, the proportion of physiotherapists who administer this testing/training, and the barriers that currently exist across different practice environments. A secondary objective is to identify the learning needs of physiotherapists for the development of an education curriculum in aerobic exercise testing and training with electrocardiograph (ECG) administration and interpretation. National, cross-sectional survey. Registered physiotherapists practicing in Canada. Out of 137 participants, most (75%) physiotherapists prescribed aerobic exercise on a regular basis (weekly); however, 65% had never conducted an aerobic exercise test. There were no significant differences in frequency of aerobic exercise testing across different practice environments or across years of physiotherapy experience. Physiotherapists perceived the main barriers to aerobic exercise testing as being a lack of equipment/space (78%), time (65%), and knowledge (56%). Although most (82%) were uncomfortable administering 12-lead ECG-monitored aerobic exercise tests, 60% stated they would be interested in learning more about ECG interpretation. This study found that physiotherapists are regularly implementing aerobic exercise. This exercise was infrequently guided by formal aerobic exercise testing, which could increase access to safe and effective exercise within the optimal aerobic training zone. As well, this could facilitate training in patients with cardiovascular diagnoses that require additional testing for medical clearance. Increased ECG training and access to equipment for physiotherapists may augment pre-screening aerobic exercise testing. This training should include learning the key arrhythmias for aerobic exercise test termination as defined by the American College of Sports Medicine.

In 2007, Alberta became the first Canadian jurisdiction to grant pharmacists a wide range of prescribing privileges. Our objective was to understand what factors influence pharmacists' adoption of prescribing using a model for the Diffusion of Innovations in healthcare services. Pharmacists participated in semi-structured telephone interviews to discuss their prescribing practices and explore the facilitators and barriers to implementation. Pharmacists working in community, hospital, PCN, or other settings were selected using a mix of random and purposive sampling. Two investigators independently analyzed each transcript using an Interpretive Description approach to identify themes. Analyses were informed by a model explaining the Diffusion of Innovations in health service organizations. Thirty-eight participants were interviewed. Prescribing behaviours varied from non-adoption through to product, disease, and patient focused use of prescribing. Pharmacists' adoption of prescribing was dependent on the innovation itself, adopter, system readiness, and communication and influence. Adopting pharmacists viewed prescribing as a legitimization of previous practice and advantageous to instrumental daily tasks. The complexity of knowledge required for prescribing increased respectively in product, disease and patient focused prescribing scenarios. Individual adopters had higher levels of self-efficacy toward prescribing skills. At a system level, pharmacists who were in practice settings that were patient focused were more likely to adopt advanced prescribing practices, over those in product-focused settings. All pharmacists stated that physician relationships impacted their prescribing behaviours and individual pharmacists' decisions to apply for independent prescribing privileges. Diffusion of Innovations theory was helpful in understanding the multifaceted nature of pharmacists' adoption of prescribing. The characteristics of the prescribing model itself which

Background Previous studies have shown that ibuprofen is detrimental to tissue healing following acute injury; however, the effects of ibuprofen when combined with non-injurious exercise are debated. Hypothesis We hypothesized that administration of ibuprofen to rats undergoing a non-injurious treadmill exercise protocol would abolish the beneficial adaptations found with exercise but have no effect on sedentary muscle and tendon properties. Study Design Controlled laboratory study Methods Rats were divided into exercise or cage activity (sedentary) groups and acute (a single bout of exercise followed by 24 hours of rest) and chronic (2 or 8 weeks of repeated exercise) time points. Half of the rats received ibuprofen to investigate the effects of this drug over time when combined with different activity levels (exercise and sedentary). Supraspinatus tendons were used for mechanical testing and histology (organization, cell shape, cellularity), and supraspinatus muscles were used for morphological (fiber CSA, centrally nucleated fibers) and fiber type analysis. Results Chronic intake of ibuprofen did not impair supraspinatus tendon organization or mechanical adaptations (stiffness, modulus, max load, max stress, dynamic modulus, or viscoelastic properties) to exercise. Tendon mechanical properties were not diminished and in some instances increased with ibuprofen. In contrast, total supraspinatus muscle fiber cross-sectional area decreased with ibuprofen at chronic time points, and some fiber type-specific changes were detected. Conclusions Chronic administration of ibuprofen does not impair supraspinatus tendon mechanical properties in a rat model of exercise but does decrease supraspinatus muscle fiber cross-sectional area. Clinically, these findings suggest that ibuprofen does not detrimentally affect regulation of supraspinatus tendon adaptions to exercise but does decrease muscle growth. Individuals should be advised on the risk of decreased muscle hypertrophy

In Australia, the antibiotic resistance crisis may be partly alleviated by reducing antibiotic use in general practice, which has relatively high prescribing rates - antibiotics are mostly prescribed for acute respiratory infections, for which they provide only minor benefits. Current surveillance is inadequate for monitoring community antibiotic resistance rates, prescribing rates by indication, and serious complications of acute respiratory infections (which antibiotic use earlier in the infection may have averted), making target setting difficult. Categories of interventions that may support general practitioners to reduce prescribing antibiotics are: regulatory (eg, changing the default to "no repeats" in electronic prescribing, changing the packaging of antibiotics to facilitate tailored amounts of antibiotics for the right indication and restricting access to prescribing selected antibiotics to conserve them), externally administered (eg, academic detailing and audit and feedback on total antibiotic use for individual GPs), interventions that GPs can individually implement (eg, delayed prescribing, shared decision making, public declarations in the practice about conserving antibiotics, and self-administered audit), supporting GPs' access to near-patient diagnostic testing, and public awareness campaigns. Many unanswered clinical research questions remain, including research into optimal implementation methods. Reducing antibiotic use in Australian general practice will require a range of approaches (with various intervention categories), a sustained effort over many years and a commitment of appropriate resources and support.

Cardiovascular benefits of exercise

Full Text Available Shashi K AgarwalMedical Director, Agarwal Health Center, NJ, USAAbstract: Regular physical activity during leisure time has been shown to be associated with better health outcomes. The American Heart Association, the Centers for Disease Control and Prevention and the American College of Sports Medicine all recommend regular physical activity of moderate intensity for the prevention and complementary treatment of several diseases. The therapeutic role of exercise in maintaining good health and treating diseases is not new. The benefits of physical activity date back to Susruta, a 600 BC physician in India, who prescribed exercise to patients. Hippocrates (460–377 BC wrote “in order to remain healthy, the entire day should be devoted exclusively to ways and means of increasing one's strength and staying healthy, and the best way to do so is through physical exercise.” Plato (427–347 BC referred to medicine as a sister art to physical exercise while the noted ancient Greek physician Galen (129–217 AD penned several essays on aerobic fitness and strengthening muscles. This article briefly reviews the beneficial effects of physical activity on cardiovascular diseases.Keywords: exercise, cardiovascular disease, lifestyle changes, physical activity, good health

Evacuation exercise at the Kindergarten

CERN Multimedia

2001-01-01

Every year fire evacuation exercises are organized through out CERN and our facility's Kindergarten is no exception. Just a few weeks ago, a fire simulation was carried out in the Kindergarten kitchen facility using synthetic smoke. The purpose of the exercise was to teach staff to react in a disciplined and professional manner when in the presence of danger. The simulation is always carried out at a random time so as to ensure that people in the area under the test are not aware of the exercise. For the Kindergarten the exercise was held early in the school year so as to train those who are new to the establishment. The evacuation was a complete success and all went as it was supposed to. When the children and teachers smelt smoke they followed the prescribed evacuation routes and left the building immediately. Once outside the situation was revealed as an exercise and everyone went back to business as usual, everyone that is, except the fire brigade and fire inspector.  The fire brigade checked t...

Exercise training is an essential component of falls prevention strategies, but they do not fully address components of physical function that leads to falls. The training approaches to achieve this may not be perceived as appropriate or even feasible in older adults. This study aims to assess the perceived feasibility and acceptability of novel exercise training approaches not usually prescribed to older adults. Fourteen adults were exposed to conceptually and physically demanding exercises. Interviews were then conducted to determine perceptions and acceptability of individual exercise tasks. Qualitative thematic analysis was used to identify themes. Safety and confidence, acceptability, and population participation were the key themes identified. Staff knowledge, presence, program design, and overt safety equipment were important for alleviating initial apprehension. Although physically demanding, participants expressed satisfaction when challenged. Prior disposition, understanding the value, and the appeal of novel exercises were perceived to influence program engagement. Given the evidence for acceptability, this type of training is feasible and may be appropriate as part of an exercise training program for older adults. Further research should be conducted to confirm that the physical adaptations to exercise training approaches as presented in this study occur in a similar manner to that observed in younger adults, and to also determine whether these adaptations lead to prolonged independence and reduced falls in older adults compared to usual care.

To determine whether patients with stroke receiving rehabilitation for upper limb deficits using smart technology (video and reminder functions) demonstrate greater adherence to prescribed home exercise programmes and better functional outcomes when compared with traditional paper-based exercise prescription. Randomized controlled trial comparing upper limb home exercise programmes supported by video and automated reminders on smart technology, with standard paper-based home exercise programmes. A community rehabilitation programme within a large metropolitan health service. Patients with stroke with upper limb deficits, referred for outpatient rehabilitation. Participants were randomly assigned to the control (paper-based home exercise programme) or intervention group (home exercise programme filmed on an electronic tablet, with an automated reminder). Both groups completed their prescribed home exercise programme for four weeks. The primary outcome was adherence using a self-reported log book. Secondary outcomes were change in upper limb function and patient satisfaction. A total of 62 participants were allocated to the intervention ( n = 30) and control groups ( n = 32). There were no differences between the groups for measures of adherence (mean difference 2%, 95% CI -12 to 17) or change in the Wolf Motor Function Test log transformed time (mean difference 0.02 seconds, 95% CI -0.1 to 0.1). There were no between-group differences in how participants found instructions ( p = 0.452), whether they remembered to do their exercises ( p = 0.485), or whether they enjoyed doing their exercises ( p = 0.864). The use of smart technology was not superior to standard paper-based home exercise programmes for patients recovering from stroke. This trial design was registered prospectively with the Australian and New Zealand Clinical Trials Register, ID: ACTRN 12613000786796. http://www.anzctr.org.au/trialSearch.aspx.

Surveillance of physicians' prescribing patterns and the accumulation and sale of these data for pharmaceutical marketing are currently the subjects of legislation in several states and action by state and national medical associations. Contrary to common perception, the growth of the health care information organization industry has not been limited to the past decade but has been building slowly over the past 50 years, beginning in the 1940s when growth in the prescription drug market fueled industry interest in understanding and influencing prescribing patterns. The development of this surveillance system was not simply imposed on the medical profession by the pharmaceutical industry but was developed through the interactions of pharmaceutical salesmen, pharmaceutical marketers, academic researchers, individual physicians, and physician organizations. Examination of the role of physicians and physician organizations in the development of prescriber profiling is directly relevant to the contemporary policy debate surrounding this issue.

OBJECTIVE The optimal approach to auditing outpatient antimicrobial prescribing has not been established. We assessed how different types of electronic data-including prescriptions, patient-visits, and International Classification of Disease, Tenth Revision (ICD-10) codes-could inform automated antimicrobial audits. DESIGN Outpatient visits during 2016 were retrospectively reviewed, including chart abstraction, if an antimicrobial was prescribed (cohort 1) or if the visit was associated with an infection-related ICD-10 code (cohort 2). Findings from cohorts 1 and 2 were compared. SETTING Primary care clinics and the emergency department (ED) at the Iowa City Veterans Affairs Medical Center. RESULTS In cohort 1, we reviewed 2,353 antimicrobial prescriptions across 52 providers. ICD-10 codes had limited sensitivity and positive predictive value (PPV) for validated cases of cystitis and pneumonia (sensitivity, 65.8%, 56.3%, respectively; PPV, 74.4%, 52.5%, respectively). The volume-adjusted antimicrobial prescribing rate was 13.6 per 100 ED visits and 7.5 per 100 primary care visits. In cohort 2, antimicrobials were not indicated in 474 of 851 visits (55.7%). The antimicrobial overtreatment rate was 48.8% for the ED and 59.7% for primary care. At the level of the individual prescriber, there was a positive correlation between a provider's volume-adjusted antimicrobial prescribing rate and the individualized rates of overtreatment in both the ED (r=0.72; P<.01) and the primary care setting (r=0.82; P=0.03). CONCLUSIONS In this single-center study, ICD-10 codes had limited sensitivity and PPV for 2 infections that typically require antimicrobials. Electronically extracted data on a provider's rate of volume-adjusted antimicrobial prescribing correlated with the frequency at which unnecessary antimicrobials were prescribed, but this may have been driven by outlier prescribers.

Full Text Available The aim of this review was to identify the effectiveness of therapies added on to conventional exercise training to maximise exercise capacity in patients with chronic obstructive pulmonary disease (COPD. Electronic databases were searched, identifying trials comparing exercise training with exercise training plus “add-on” therapy. Outcomes included peak oxygen uptake (V′O2peak, work rate and incremental/endurance cycle and field walking tests. Individual trial effects on exercise capacity were extracted and collated into eight subgroups and pooled for meta-analysis. Sensitivity analyses were conducted to explore the stability of effect estimates across studies employing patient-centred designs and those deemed to be of “high” quality (PEDro score >5 out of 10. 74 studies (2506 subjects met review inclusion criteria. Interventions spanned a broad scope of clinical practice and were most commonly evaluated via the 6-min walking distance and V′O2peak. Meta-analysis revealed few clinically relevant and statistically significant benefits of “add-on” therapies on exercise performance compared with exercise training. Benefits favouring “add-on” therapies were observed across six different interventions (additional exercise training, noninvasive ventilation, bronchodilator therapy, growth hormone, vitamin D and nutritional supplementation. The sensitivity analyses included considerably fewer studies, but revealed minimal differences to the primary analysis. The lack of systematic benefits of “add-on” interventions is a probable reflection of methodological limitations, such as “one size fits all” eligibility criteria, that are inherent in many of the included studies of “add-on” therapies. Future clarification regarding the exact value of such therapies may only arise from adequately powered, multicentre clinical trials of tailored interventions for carefully selected COPD patient subgroups defined according to distinct

It is generally accepted that muscle adaptation to resistance exercise (REX) training is underpinned by contraction-induced, increased rates of protein synthesis and dietary protein availability. By using dynamic proteome profiling (DPP), we investigated the contribution of both synthesis and breakdown to changes in abundance on a protein-by-protein basis in human skeletal muscle. Age-matched, overweight males consumed 9 d of a high-fat, low-carbohydrate diet during which time they either undertook 3 sessions of REX or performed no exercise. Precursor enrichment and the rate of incorporation of deuterium oxide into newly synthesized muscle proteins were determined by mass spectrometry. Ninety proteins were included in the DPP, with 28 proteins exhibiting significant responses to REX. The most common pattern of response was an increase in turnover, followed by an increase in abundance with no detectable increase in protein synthesis. Here, we provide novel evidence that demonstrates that the contribution of synthesis and breakdown to changes in protein abundance induced by REX differ on a protein-by-protein basis. We also highlight the importance of the degradation of individual muscle proteins after exercise in human skeletal muscle.-Camera, D. M., Burniston, J. G., Pogson, M. A., Smiles, W. J., Hawley, J. A.

To prescribe codeine or not to prescribe codeine?

A recently published study in Pediatrics by Kaiser et al. (2014; Epub April 21, DOI: 10.1542/peds.2013-3171) reported that on average, over the past decade, children aged 3 to 17 were prescribed approximately 700,000 prescriptions for codeine-containing products each year in association with emergency department (ED) visits. Although, guidelines from the American Academy of Pediatrics issued warnings in 1997 and reaffirmed their concerns regarding the safety and effectiveness of codeine in 2006, it is still often prescribed for pain and cough associated with upper respiratory infection. With the impending rescheduling of hydrocodone combination products to Schedule II, physicians and mid-level prescribers may be compelled to prescribe codeine-containing products (e.g., with acetaminophen) due to reduced administrative burden and limits on Schedule II prescriptive authority for nurse practitioners and physician assistants in some states. This commentary expounds on the safety and effectiveness concerns of codeine, with a primary focus on patients in the ED setting.

Tiedemann, Anne; Sherrington, Catherine; Close, Jacqueline C T; Lord, Stephen R

Falls affect a significant number of older Australians and present a major challenge to health care providers and health systems. The purpose of this statement is to inform and guide exercise practitioners and health professionals in the safe and effective prescription of exercise for older community-dwelling people with the goal of preventing falls. Falls in older people are not random events but can be predicted by assessing a number of risk factors. Of particular importance are lower limb muscle strength, gait and balance, all of which can be improved with appropriate exercise. There is now extensive evidence to demonstrate that many falls are preventable, with exercise playing a crucial role in prevention. Research evidence has identified that programs which include exercises that challenge balance are more effective in preventing falls than those which do not challenge balance. It is important for exercise to be progressively challenging, ongoing and of sufficient dose to maximise its benefits in reducing falls. Other (non-exercise) interventions are necessary for certain people with complex medical conditions or recent hospitalisation and risk factors relating to vision and the use of psychotropic medications. Qualified exercise professionals are well placed to implement the research evidence and to prescribe and supervise specific exercise aimed at preventing falls in both healthy older community-dwelling people and those with co-morbidities.

Endorphins, Exercise, and Addictions: A Review of Exercise Dependence

Directory of Open Access Journals (Sweden)

Andrea Leuenberger

2006-01-01

Full Text Available Endorphins are endogenous opioids released from the pituitary gland that are believed to mediate analgesia, induce euphoria, and play a role in the reward system in the brain. It has been suggested that endorphins are responsible for creating the relaxed psychological state known as runners high. Studies examining the relationship between vigorous exercise and blood plasma endorphin levels have produced conflicting results. Some indicate a significant increase of endorphins during or after exercise while others do not. Inconsistent methods and experimental techniques have made it difficult to determine a relationship between exercise and endorphin elevations. Research has shown that opioidergic activity plays a role in addictions by mediating the development of reinforcing qualities of certain activities and substances. A newly-established condition known as exercise dependence defines exercise as an addiction, characterized by a compulsion to exercise excessively even when the consequences are harmful to an individuals health, family relationships, and personal wealth (Griffiths, 1997; Hausenblas and Downs, 2002; Loumidis and Wells, 1998. Various surveys and questionnaires have been validated for determining the level of an individuals dependence on and need for exercise. As researchers define a clear relationship between vigorous exercise and increased endorphin levels, causes of exercise dependence can be more concretely determined. Exercise dependence is not currently recognized by the DSM-IV, but its presence in certain human behaviors (similar to those of alcoholics and drug addicts indicate that it should be precisely defined.

Growth hormone (GH) is regulated, suppressed and stimulated by numerous physiological stimuli. However, it is believed that obesity disrupts the physiological and pathological factors that regulate, suppress or stimulate GH release. Pulsatile GH has been potently stimulated in healthy subjects by both aerobic and resistance exercise of the right intensity and duration. GH modulates fuel metabolism, reduces total fat mass and abdominal fat mass, and could be a potent stimulus of lipolysis when administered to obese individuals exogenously. Only pulsatile GH has been shown to augment adipose tissue lipolysis and, therefore, increasing pulsatile GH response may be a therapeutic target. This review discusses the factors that cause secretion of GH, how obesity may alter GH secretion and how both aerobic and resistance exercise stimulates GH, as well as how exercise of a specific intensity may be used as a stimulus for GH release in individuals who are obese. Only five prior studies have investigated exercise as a stimulus of endogenous GH in individuals who are obese. Based on prior literature, resistance exercise may provide a therapeutic target for releasing endogenous GH in individuals who are obese if specific exercise programme variables are utilized. Biological activity of GH indicates that this may be an important precursor to beneficial changes in body fat and lean tissue mass in obese individuals. However, additional research is needed including what molecular GH variants are acutely released and involved at target tissues as a result of different exercise stimuli and what specific exercise programme variables may serve to stimulate GH in individuals who are obese.

Exercise training is a core component of cardiac rehabilitation (CR), however, little information exists regarding the specific exercise interventions currently provided for coronary heart disease in Australian practice. We aimed to analyse the current status of exercise-based CR services across Australia. Cross-sectional survey. Australian sites offering exercise-based CR were identified from publically available directories. All sites were invited by email to participate in an online Survey Monkey questionnaire between October 2014 and March 2015, with reminders via email and phone follow-up. Questions investigated the demographics and format of individual programmes, as well as specific exercise training characteristics. 297 eligible programmes were identified, with an 82% response rate. Most sites (82%) were based at hospital or outpatient centres, with home (15%), community (18%) or gym-based options (5%) less common. While CR was most often offered in a comprehensive format (72% of sites), the level of exercise intervention varied greatly among programmes. Most frequently, exercise was prescribed 1-2 times per week for 60 min over 7 weeks. Almost one-quarter (24%) had a sole practitioner supervising exercise, although the majority used a nurse/physiotherapist combination. Low to moderate exercise intensities were used in 60% of programmes, however, higher intensity prescriptions were not uncommon. Few sites (technology, such as mobile phones or the internet, to deliver or support exercise training. While advances have been made towards providing flexible and accessible exercise-based CR, much of Australia's service remains within traditional models of care. A continuing focus on service improvement and evidence-based care should, therefore, be considered a core aim of those providing exercise for CR in order to improve health service delivery and optimise outcomes for patients.

Physically active individuals show greater conditioned pain modulation (CPM) compared with less active individuals. Understanding the effects of acute exercise on CPM may allow for a more targeted use of exercise in the management of pain. This study investigated the effects of acute isometric exercise on CPM. In addition, the between-session and within-session reliability of CPM was investigated. Experimental, randomized crossover study. Laboratory at Marquette University. Thirty healthy adults (19.3±1.5 years, 15 males). Subjects underwent CPM testing before and after isometric exercise (knee extension, 30% maximum voluntary contraction for three minutes) and quiet rest in two separate experimental sessions. Pressure pain thresholds (PPTs) at the quadriceps and upper trapezius muscles were assessed before, during, and after ice water immersions. PPTs increased during ice water immersion (i.e., CPM), and quadriceps PPT increased after exercise (P CPM decreased similarly following exercise and quiet rest (P > 0.05). CPM within-session reliability was fair to good (intraclass correlation coefficient [ICC] = 0.43-0.70), and the between-session reliability was poor (ICC = 0.20-0.35). Due to the variability in the systemic exercise-induced hypoalgesia (EIH) response, participants were divided into systemic EIH responders (N = 9) and nonresponders (N = 21). EIH responders experienced attenuated CPM following exercise (P = 0.03), whereas the nonresponders showed no significant change (P > 0.05). Isometric exercise decreased CPM in individuals who reported systemic EIH, suggesting activation of shared mechanisms between CPM and systemic EIH responses. These results may improve the understanding of increased pain after exercise in patients with chronic pain and potentially attenuated CPM.

Philosopher Hannah Arendt maintains that everyone has the right to appear in public as an embodied, singular individual. Because of the stigma attached to epilepsy, many with this condition are denied this right. Using grounded theory techniques, the author analyzes uploads of epilepsy on YouTube. The author argues that personal uploads on YouTube are the only mass media examples in which those with epilepsy can exercise their right to appear without the interpretation of intermediaries. Emerging themes relating to "the right to appear" allow social workers to deepen understanding of this and other devastating, often invisible and sometimes life-threatening illnesses.

Many individuals with lower limb loss report concern with walking ability after completing structured traditional rehabilitation. The purpose of this study was to explore the impact of a supervised community-based exercise program on balance, balance confidence, and gait in individuals with lower limb amputation. Repeated measures. The supervised exercise program was offered biweekly for 6 weeks. The GAITRite System by CIR Systems, Inc., the Figure-of-8 Walk Test, and Activity-specific Balance Confidence Scale were used to measure clinical outcomes pre- and post-intervention. In total, 16 participants with lower limb amputation (mean age: 50.8 years) completed the study. A multivariate, repeated measures analysis of variance indicated a statistically significant effect of training across six clinical outcome measures ( F(6, 10) = 4.514, p = .018). Moderate effect sizes were found for the Figure-of-8 Walk Test ( η 2 = .586), Activity-specific Balance Confidence Scale ( η 2 = .504), and gait velocity at comfortable walking speed ( η 2 = .574). The average increase in gait speed was clinically meaningful at .14 m/s. The supervised community-based exercise program implemented in this study was designed to address specific functional needs for individuals with lower limb loss. Each participant experienced clinically meaningful improvements in balance, balance confidence, and walking ability. Clinical relevance The provision of a supervised community-based exercise program, after traditional rehabilitation, provides opportunity to offer a continuum of care that may enhance prosthetic functional ability and active participation in the community for individuals with lower limb amputation.

Non-exercise physical activity (NEPA) and/or non-exercise activity thermogenesis (NEAT) reductions may occur from diet and/or exercise-induced negative energy balance interventions, resulting in less-than-expected weight loss. This systematic review describes the effects of prescribed diet and/or physical activity (PA)/exercise on NEPA and/or NEAT in adults. Studies were identified from PubMed, web-of-knowledge, Embase, SPORTDiscus, ERIC and PsycINFO searches up to 1 March 2017. Eligibility criteria included randomised controlled trials (RCT), randomised trials (RT) and non-randomised trials (NRT); objective measures of PA and energy expenditure; data on NEPA, NEAT and spontaneous PA; ≥10 healthy male/female aged>18 years; and ≥7 d length. The trial is registered at PROSPERO-2017-CRD42017052635. In all, thirty-six articles (RCT-10, RT-9, NRT-17) with a total of seventy intervention arms (diet, exercise, combined diet/exercise), with a total of 1561 participants, were included. Compensation was observed in twenty-six out of seventy intervention arms (fifteen studies out of thirty-six reporting declines in NEAT (eight), NEPA (four) or both (three)) representing 63, 27 and 23 % of diet-only, combined diet/exercise, and exercise-only intervention arms, respectively. Weight loss observed in participants who decreased NEAT was double the weight loss found in those who did not compensate, suggesting that the energy imbalance degree may lead to energy conservation. Although these findings do not support the hypothesis that prescribed diet and/or exercise results in decreased NEAT and NEPA in healthy adults, the underpowered trial design and the lack of state-of-the-art methods may limit these conclusions. Future studies should explore the impact of weight-loss magnitude, energetic restriction degree, exercise dose and participant characteristics on NEAT and/or NEPA.

Stages of change in exercise behaviour have been shown to be associated with health-related quality of life (HRQoL) in overweight/obese adults. However, studies examining this relationship have not used questionnaires specifically designed for such a population. The present study assessed the impact of stages of change (SOC) for exercise, using the transtheoretical model, on the HRQoL, using the quality of life, obesity and dietetics (QOLOD) scale, an obesity-specific QoL questionnaire. Our hypothesis was that the more people are in the advanced stages of behavioural change, the better their HRQoL. A total of 214 consecutive obese individuals (148 women/66 men, mean age 47.4 ± 14.0 years, BMI 37.2 ± 8.4 kg/m2) were included in the cross-sectional study, and all completed SOC and QOLOD questionnaires. Multivariate analysis of covariance (MANCOVA) established significant effects on the overall composite of the five dimensions of the QOLOD (P food (P = 0.13) or on the dieting experience (P = 0.13), two dimensions evaluating attitudes toward food. In obese/overweight individuals, the HRQoL varies with the SOC, with those in the more advanced behavioural stages reporting better HRQoL. However, dimensions related to food showed no differences according to SOC, confirming the complexity of the relationship between exercise and nutrition, and the need for further studies to acquire a more complete understanding of their underlying mechanisms.

Parkinson disease is a progressive neurologic disorder. Limited evidence suggests endurance exercise modifies disease severity, particularly high-intensity exercise. To examine the feasibility and safety of high-intensity treadmill exercise in patients with de novo Parkinson disease who are not taking medication and whether the effect on motor symptoms warrants a phase 3 trial. The Study in Parkinson Disease of Exercise (SPARX) was a phase 2, multicenter randomized clinical trial with 3 groups and masked assessors. Individuals from outpatient and community-based clinics were enrolled from May 1, 2012, through November 30, 2015, with the primary end point at 6 months. Individuals with idiopathic Parkinson disease (Hoehn and Yahr stages 1 or 2) aged 40 to 80 years within 5 years of diagnosis who were not exercising at moderate intensity greater than 3 times per week and not expected to need dopaminergic medication within 6 months participated in this study. A total of 384 volunteers were screened by telephone; 128 were randomly assigned to 1 of 3 groups (high-intensity exercise, moderate-intensity exercise, or control). High-intensity treadmill exercise (4 days per week, 80%-85% maximum heart rate [n = 43]), moderate-intensity treadmill exercise (4 days per week, 60%-65% maximum heart rate [n = 45]), or wait-list control (n = 40) for 6 months. Feasibility measures were adherence to prescribed heart rate and exercise frequency of 3 days per week and safety. The clinical outcome was 6-month change in Unified Parkinson's Disease Rating Scale motor score. A total of 128 patients were included in the study (mean [SD] age, 64 [9] years; age range, 40-80 years; 73 [57.0%] male; and 108 [84.4%] non-Hispanic white). Exercise rates were 2.8 (95% CI, 2.4-3.2) days per week at 80.2% (95% CI, 78.8%-81.7%) maximum heart rate in the high-intensity group and 3.2 (95% CI, 2.8-3.6; P = .13) days per week at 65.9% (95% CI, 64.2%-67.7%) maximum heart rate in the

Full Text Available This study investigated the influence of aerobic capacity on the activation of the central serotonergic system and exercise fatigue in young men that ingested a selective serotonin reuptake inhibitor and were then subjected to moderate-intensity physical exercise. The maximal oxygen consumption of sixteen volunteers was measured during an incremental test. The volunteers were divided into two groups: subjects with higher (HAC and lower (LAC aerobic capacities. The volunteers were subjected to four experimental trials in which they ingested either placebo or paroxetine (10, 20 or 40 mg and, 4.5 h later, cycled at 60% of their maximal power output until reaching fatigue. None of the three paroxetine doses influenced the total exercise time in the LAC group. However, for the HAC group, the time to fatigue in the 20 mg paroxetine condition was 15% less than that in the placebo condition (76.3 ± 5.1 min vs. 90.0 ± 7.9 min; p < 0.05. The time to fatigue was higher in the HAC group than in the LAC group for all treatments. Our results provide additional evidence that aerobic capacity modulates the activity of the serotonergic system. However, contrary to what would be expected considering previous reports, the activation of the serotonergic system in exercising subjects in the HAC group was not less than that in the LAC group.

General Exercise Does Not Improve Long-Term Pain and Disability in Individuals With Whiplash-Associated Disorders: A Systematic Review.

Study Design Systematic review of randomized controlled trials. Background General exercise, defined as purposeful physical activity involving repetitive exercises and incorporating multiple muscle groups, is frequently used in the management of whiplash-associated disorders (WADs). Evidence supporting its efficacy is not well established. Objectives To determine whether general exercise is effective in reducing pain and disability in people with WAD. Methods Studies published in English in peer-reviewed journals between January 1990 and May 2015 were eligible if they evaluated a general exercise intervention compared with a different intervention or control. Studies were required to evaluate pain and disability at medium-term (6-14 weeks) and long-term (52 weeks) follow-ups. The mean ± SD and sample size were recorded for follow-up scores and for change scores from baseline to follow-up. Results Of the 3 high-quality studies that were eligible for inclusion, none investigated general exercise alone. There were no clinically meaningful differences between comprehensive exercise programs, which included general exercise, and minimal intervention controls in the medium and long term. No studies directly compared general exercise with a no-treatment control. All included studies used different control interventions, preventing meta-analysis. Conclusion A lack of significant long-term improvements from general exercise interventions in individuals with WAD was identified. This finding differs from the positive benefits of general exercise for other musculoskeletal conditions. This may, in part, relate to the complexity of whiplash conditions. This may also reflect the challenge of exercise prescription in this population, where the need for sufficient intensity is balanced against the impact that exercise has on pain.

Full Text Available This study aimed to investigate the effect of double oscillation exercise combined with elastic band exercise on the strength and thickness ratio of the scapular stabilizing muscles in healthy young individuals. A total of 30 subjects (17 male, 13 female were randomly assigned to an elastic band exercise group (EBG (n = 15 or an elastic band plus double oscillation exercise group (EB-DOG (n = 15. A total of 28 subjects completed the experiment and evaluation. Patients in the EBG performed the elastic band exercise for shoulder flexion, extension, abduction, adduction, horizontal abduction/adduction, and internal/external rotation for 30 minutes/session, five times/week, for four weeks. Patients in the EB-DOG performed the elastic band exercise for 15 minutes and the double oscillation exercise in three planes of motion (frontal, sagittal, and transverse, using a Bodyblade® for 15 minutes/session, five times/week, for four weeks. Shoulder muscle strength was assessed using a manual muscle test device during maximal voluntary isometric contraction (MVIC, while the thicknesses of the scapular stabilizing muscles were assessed using rehabilitative ultrasound imaging both at rest and during MVIC. Both groups had significant effects on shoulder muscle strength, however, there was no significant difference between the two groups for change value of shoulder muscle strength (Bonferroni correction p < 0.005. Significant differences were observed in the group × time interactions for horizontal abduction, external rotation, and protraction. There was a statistically significant improvement in thickness ratio of LT and SA in the EB-DOG and no significant difference was founded in EBG (Bonferroni correction p < 0.006. In comparison between the two groups, EB-DOG showed a significant change in the thickness ratio of LT compared to EBG. In addition, significant differences were observed for the group × time interactions for the thickness ratio of the LT (F

Implementation of electronic prescribing system can overcome many problems of the paper prescribing system, and provide numerous opportunities of more effective and advantageous prescribing. Successful implementation of such a system requires complete and deep understanding of work content, human force, and workflow of paper prescribing. The current study was designed in order to model the current business process of outpatient prescribing in Iran and clarify different actions during this process. In order to describe the prescribing process and the system features in Iran, the methodology of business process modeling and analysis was used in the present study. The results of the process documentation were analyzed using a conceptual model of workflow elements and the technique of modeling "As-Is" business processes. Analysis of the current (as-is) prescribing process demonstrated that Iran stood at the first levels of sophistication in graduated levels of electronic prescribing, namely electronic prescription reference, and that there were problematic areas including bottlenecks, redundant and duplicated work, concentration of decision nodes, and communicative weaknesses among stakeholders of the process. Using information technology in some activities of medication prescription in Iran has not eliminated the dependence of the stakeholders on paper-based documents and prescriptions. Therefore, it is necessary to implement proper system programming in order to support change management and solve the problems in the existing prescribing process. To this end, a suitable basis should be provided for reorganization and improvement of the prescribing process for the future electronic systems.

concern for the widespread implementation of BFR, use of this training mechanism may also have negative consequences in the absence of disease. That is, even normal, healthy individuals performing resistance training exercise with BFR are potentially at increased risk for deleterious cardiovascular events. This review provides a brief yet detailed overview of the mechanisms underlying the autonomic cardiovascular response to exercise with BFR. A more complete understanding of the consequences of BFR training is needed before this technique is passively explored by the layman athlete or prescribed by a health care professional.

The aim of this study was to assess both psychological distress and personality characteristics associat with primary exercise dependence. A cross-sectional study was carried out with adult habitual physical exercisers. A total of 79 participants voluntarily completed a package of self-report questionnaires including the Exercise Dependence Questionnaire (EDQ), the Eating Disorder Inventory II (EDI-2), the Temperament and Character Inventory (TCI), the Attitude Toward Self scale (ATS), Muscle Dysmorphia Questionnaire (MDQ), and the Symptom Questionnaire (SQ). Significant differences were found in the EDQ exercise for weight control subscale with regard to gender, as well as in the EDI-2 total score and 5 of its subscales, with higher scores for females compared to males. Participants reporting primary exercise dependence (n=32) were more likely to present with disordered eating patterns than controls (n=47). They also showed higher levels of harm avoidance and persistence on the TCI, as well as lower self-directness. Furthermore, primary exercise dependents scored higher on the ATS dysmorphophobia subscale, as well as on the MDQ total score and the anxiety and hostility subscales of the SQ compared to controls. These findings highlight the importance of performing a clinical assessment of psychological symptoms and personality characteristics that might be associated with primary exercise dependence.

Background Pulling from Self-Determination Theory (SDT; Deci & Ryan, 1985), this study examined whether individuals classified as 'nondependent-symptomatic' and 'nondependent-asymptomatic' for exercise dependence differed in terms of reported levels of exercise-related psychological need satisfaction, self-determined versus controlling motivation and exercise behavior. In addition, we examined the type of motivational regulations predicting exercise behavior among these different groups, and their role as mediators between psychological need satisfaction and behavioral outcomes. Methods Participants (N = 339) completed measures of exercise-specific psychological need satisfaction, motivational regulations, exercise behavior and exercise dependence. Results Nondependent-symptomatic individuals reported higher levels of competence need satisfaction and all forms of motivational regulation, compared to nondependent-asymptomatic individuals. Introjected regulation approached significance as a positive predictor of strenuous exercise behavior for symptomatic individuals. Identified regulation was a positive predictor of strenuous exercise, and completely mediated the relationship between competence need satisfaction and strenuous exercise behavior, for asymptomatic individuals. Conclusions The findings reinforce the applicability of SDT to understanding the quantity and quality of engagement in exercise.

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

Directory of Open Access Journals (Sweden)

Alessandro Capitanini

2014-07-01

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.

Does Motivation for Exercise Influence Post-Exercise Snacking Behavior?

It is well established that regular exercise plays an important role in achieving a number of health and wellbeing outcomes. However, certain post-exercise behaviors, including the consumption of unhealthy high-calorie foods, can counteract some of the benefits of physical activity. There are at least three overlapping pathways through which exercise may increase the likelihood of consuming pleasurable but unhealthy foods: through impulsive cognitive processes, reflective cognitive processes, and/or physiological responses. It is argued in this paper that motivation toward exercise can influence each of these pathways. Drawing from literature from various domains, we postulate that controlled exercise motivation, as opposed to autonomous exercise motivation, is more likely to influence each of these pathways in a manner that leaves individuals susceptible to the post-exercise consumption of pleasurable but unhealthy foods.

To report the introduction and impact of non-medical prescribing, initiated to improve patient pathways for those presenting with dizziness and balance disorders. The Southport and Ormskirk physiotherapy-led vestibular clinic sees and treats all patients with dizziness and balance disorders referred to the ENT department. Letters are triaged by an audiologist, who also performs an otological examination and hearing test; this is followed by an assessment with the independent prescriber physiotherapist. An ENT consultant is nearby if joint consultation is needed. Diagnoses, treatments and patient satisfaction were studied, with an analysis of the impact of medication management (stopping or starting medicines) on patients and service. In 12 months, 413 new patients with dizziness and balance disorders had appointments. The most common diagnoses were benign paroxysmal positional vertigo and vestibular migraine. Eighty-four per cent of patients required self-management strategies, 50 per cent exercise therapy, 48 per cent medication management and 24 per cent a particle repositioning manoeuvre. Patient satisfaction was high (99 per cent). Having an independent prescriber physiotherapist leading the balance clinic has reduced the number of hospital visits and onward referrals. Nearly half of all patients required medication management as part of their dizziness or balance treatment.

Tai Chi Chuan Exercise for Patients with Cardiovascular Disease

2013-01-01

Full Text Available Exercise training is the cornerstone of rehabilitation for patients with cardiovascular disease (CVD. Although high-intensity exercise has significant cardiovascular benefits, light-to-moderate intensity aerobic exercise also offers health benefits. With lower-intensity workouts, patients may be able to exercise for longer periods of time and increase the acceptance of exercise, particularly in unfit and elderly patients. Tai Chi Chuan (Tai Chi is a traditional Chinese mind-body exercise. The exercise intensity of Tai Chi is light to moderate, depending on its training style, posture, and duration. Previous research has shown that Tai Chi enhances aerobic capacity, muscular strength, balance, and psychological well-being. Additionally, Tai Chi training has significant benefits for common cardiovascular risk factors, such as hypertension, diabetes mellitus, dyslipidemia, poor exercise capacity, endothelial dysfunction, and depression. Tai Chi is safe and effective in patients with acute myocardial infarction (AMI, coronary artery bypass grafting (CABG surgery, congestive heart failure (HF, and stroke. In conclusion, Tai Chi has significant benefits to patients with cardiovascular disease, and it may be prescribed as an alternative exercise program for selected patients with CVD.

Rates of participation in regular exercise are lower among individuals with arthritis than those without arthritis. This study examined perceived exercise barriers, benefits, and enablers in exercising and nonexercising adults with arthritis. Twelve focus groups were conducted with 68 adults with arthritis. Groups were segmented by exercise status, socioeconomic status, and race. Focus group discussions were transcribed verbatim and coded. NVivo software was used to extract themes for exercisers and nonexercisers. A wide range of physical, psychological, social, and environmental factors were perceived to influence exercise. Some of these factors were similar to those in general adult samples, whereas others were unique to individuals with chronic disease. Symptoms of arthritis were barriers to exercise, yet improvements in these outcomes were also seen as potential benefits of and motivations for exercise. Exercisers had experienced these benefits and were more likely to have adapted their exercise to accommodate the disease, whereas nonexercisers desired these benefits and were more likely to have stopped exercising since developing arthritis. Health care providers' advice to exercise and the availability of arthritis-specific programs were identified as needs. This study has implications for how to market exercise to individuals with arthritis and how communities and health care professionals can facilitate the uptake of exercise. These implications are discussed.

In a previous paper, as the first of a series of three on the importance of characteristics and modalities of physical activity (PA) and exercise in the management of cardiovascular health within the general population, we concluded that, in the population at large, PA and aerobic exercise capacity clearly are inversely associated with increased cardiovascular disease risk and all-cause and cardiovascular mortality and that a dose–response curve on cardiovascular outcome has been demonstrated in most studies. More and more evidence is accumulated that engaging in regular PA and exercise interventions are essential components for reducing the severity of cardiovascular risk factors, such as obesity and abdominal fat, high BP, metabolic risk factors, and systemic inflammation. However, it is less clear whether and which type of PA and exercise intervention (aerobic exercise, dynamic resistive exercise, or both) or characteristic of exercise (frequency, intensity, time or duration, and volume) would yield more benefit for each separate risk factor. The present paper, therefore, will review and make recommendations for PA and exercise training in the management of cardiovascular health in individuals with cardiovascular risk factors. The guidance offered in this series of papers is aimed at medical doctors, health practitioners, kinesiologists, physiotherapists and exercise physiologists, politicians, public health policy makers, and individual members of the public. Based on previous and the current literature overviews, recommendations from the European Association on Cardiovascular Prevention and Rehabilitation are formulated regarding type, volume, and intensity of PA and regarding appropriate risk evaluation during exercise in individuals with cardiovascular risk factors.

The training approaches to achieve this may not be perceived as appropriate or even feasible in older adults. This study aims to assess the perceived feasibility and acceptability of novel exercise training approaches not usually prescribed to older adults. Patients and methods: Fourteen adults were exposed to conceptually and physically demanding exercises. Interviews were then conducted to determine perceptions and acceptability of individual exercise tasks. Qualitative thematic analysis was used to identify themes. Results: Safety and confidence, acceptability, and population participation were the key themes identified. Staff knowledge, presence, program design, and overt safety equipment were important for alleviating initial apprehension. Although physically demanding, participants expressed satisfaction when challenged. Prior disposition, understanding the value, and the appeal of novel exercises were perceived to influence program engagement. Conclusion: Given the evidence for acceptability, this type of training is feasible and may be appropriate as part of an exercise training program for older adults. Further research should be conducted to confirm that the physical adaptations to exercise training approaches as presented in this study occur in a similar manner to that observed in younger adults, and to also determine whether these adaptations lead to prolonged independence and reduced falls in older adults compared to usual care. Keywords: falls, balance, qualitative analysis, thematic

Does Motivation for Exercise Influence Post-Exercise Snacking Behavior?

Full Text Available It is well established that regular exercise plays an important role in achieving a number of health and wellbeing outcomes. However, certain post-exercise behaviors, including the consumption of unhealthy high-calorie foods, can counteract some of the benefits of physical activity. There are at least three overlapping pathways through which exercise may increase the likelihood of consuming pleasurable but unhealthy foods: through impulsive cognitive processes, reflective cognitive processes, and/or physiological responses. It is argued in this paper that motivation toward exercise can influence each of these pathways. Drawing from literature from various domains, we postulate that controlled exercise motivation, as opposed to autonomous exercise motivation, is more likely to influence each of these pathways in a manner that leaves individuals susceptible to the post-exercise consumption of pleasurable but unhealthy foods.

Full Text Available Recent studies have shown that the elderly exhibit a subclinical state of inflammation associated with increased adipose tissue and several comorbidities. To compare the effects of mat Pilates based exercises and resistance exercise on the serum levels of reactive C protein of high sensitivity (hs-CRP, in the abdominal circumference (AC and the body mass index (BMI in the elderly. It is a randomised clinical trial with a sample of 78 elderly individuals (median age 69 years. The active independent variable investigated was nature of treatment intervention (Pilates mat based exercises vs resistance exercise, and the dependent variables were hs-CRP level, AC and BMI. The statistical analysis used Wilcoxon signed rank and Mann-Whitney tests. The correlation between the continuous variables was assessed using Spearman’s coefficient of correlation. The data were analysed using SPSS software version 17.0, and probability values lower than 5% (p< 0.05 were considered statistically significant. Mat Pilates based exercises exhibited reductions in serum hs-CPR level (Wilcoxon signed rank test; z = -2.466, p = 0.01, BMI (Wilcoxon signed rank test; z = -3.295, p = 0.001 and AC (Wilcoxon signed rank test; z = -3.398, p = 0.01.

Cell-derived procoagulant microparticles (MP) might be able to contribute to exercise-induced changes in blood hemostasis. This study aimed to examine (i) the concentration and procoagulant activity of cell-derived MP after a moderate endurance exercise and (ii) the differences in the release, clearance, and activity of MP before and after exercise between trained and untrained individuals. All subjects performed a single bout of physical exercise on a bicycle ergometer for 90 min at 80% of their individual anaerobic threshold. MP were identified and quantified by flow cytometry measurements. Procoagulant activity of MP was measured by a prothrombinase activity assay as well as tissue factor-induced fibrin formation in MP-containing plasma. At baseline, no differences were observed for the absolute number and procoagulant activities of MP between trained and untrained subjects. However, trained individuals had a lower number of tissue factor-positive monocyte-derived MP compared with untrained individuals. In trained subjects, exercise induced a significant increase in the number of MP derived from platelets, monocytes, and endothelial cells, with maximum values at 45 min after exercise and returned to basal levels at 2 h after exercise. Untrained subjects revealed a similar increase in platelet-derived MP, but their level was still increased at 2 h after exercise, indicating a reduced clearance compared with trained individuals. Procoagulant activities of MP were increased immediately after exercise and remained elevated up to 2 h after exercise. We conclude that increased levels of MP were found in healthy individuals after an acute bout of exercise, that the amount of circulating MP contributes to an exercise-induced increase of hemostatic potential, and that there were differences in kinetic and dynamic characteristics between trained and untrained individuals.

Being physically active or, in a broader sense, simply moving more throughout each day is one of the most important components of an individual's health plan. In conjunction with regular exercise training, taking more steps in a day and sitting less are also important components of one's movement portfolio. Given this priority, health care professionals must develop enhanced skills for prescribing and guiding individualized movement programs for all their patients. An important component of a health care professional's ability to prescribe movement as medicine is competency in assessing an individual's risk for untoward events if physical exertion was increased. The ability to appropriately assess one's risk before advising an individual to move more is integral to clinical decision-making related to subsequent testing if needed, exercise prescription, and level of supervision with exercise training. At present, there is a lack of clarity pertaining to how a health care professional should go about assessing an individual's readiness to move more on a daily basis in a safe manner. Therefore, this perspectives article clarifies key issues related to prescribing movement as medicine and presents a new process for clinical assessment before prescribing an individualized movement program.

Goldman, Roberta E; Dubé, Catherine; Lapane, Kate L

2010-07-01

E-prescribing is part of a new generation of electronic solutions for the medical industry that may have great potential for improving work flow and communication between medical practices and pharmacies. In the US, it has been introduced with minimal monitoring of errors and general usability. This paper examines refill functionality in e-prescribing software. A mixed method study including focus groups and surveys was conducted. Qualitative data were collected in on-site focus groups or individual interviews with clinicians and medical office staff at 64 physician office practices. Focus group participants described their experiences with the refill functionality of e-prescribing software, provided suggestions for improving it, and suggested improvements in office procedures and software functionality. Overall, approximately 50% reduction in time spent each day on refills was reported. Overall reports of refill functionality were positive; but clinicians and staff identified numerous difficulties and glitches associated managing prescription refills. These glitches diminished over time. Benefits included time saved as well as patient convenience. Potential for refilling without thought because of the ease of use was noted. Clinicians and staff appreciated the ability to track whether patients are filling and refilling prescriptions. E-prescribing software for managing medication refills has not yet reached its full potential. To reduce work flow barriers and medication errors, software companies need to develop error reporting systems and response teams to deal effectively with problems experienced by users. Examining usability issues on both the medical office and pharmacy ends is required to identify the behavioral and cultural changes that accompany technological innovation and ease the transition to full use of e-prescribing software. 2010 Elsevier Ireland Ltd.

The Talk Test (TT) is a submaximal, incremental exercise test that has been shown to be useful in prescribing exercise training intensity. It is based on a subject's ability to speak comfortably during exercise. This study defined the amount of reduction in absolute workload intensity from an incremental exercise test using the TT to give appropriate absolute training intensity for cardiac rehabilitation patients. Patients in an outpatient rehabilitation program (N = 30) performed an incremental exercise test with the TT given every 2-minute stage. Patients rated their speech comfort after reciting a standardized paragraph. Anything other than a "yes" response was considered the "equivocal" stage, while all preceding stages were "positive" stages. The last stage with the unequivocally positive ability to speak was the Last Positive (LP), and the preceding stages were (LP-1 and LP-2). Subsequently, three 20-minute steady-state training bouts were performed in random order at the absolute workload at the LP, LP-1, and LP-2 stages of the incremental test. Speech comfort, heart rate (HR), and rating of perceived exertion (RPE) were recorded every 5 minutes. The 20-minute exercise training bout was completed fully by LP (n = 19), LP-1 (n = 28), and LP-2 (n = 30). Heart rate, RPE, and speech comfort were similar through the LP-1 and LP-2 tests, but the LP stage was markedly more difficult. Steady-state exercise training intensity was easily and appropriately prescribed at intensity associated with the LP-1 and LP-2 stages of the TT. The LP stage may be too difficult for patients in a cardiac rehabilitation program.

Objective To test experiential and behavioral processes of change as mediators of the prediction of exercise behavior by two self-regulation traits, self-efficacy and self-motivation, while controlling for exercise enjoyment. Methods Structural equation modeling was applied to questionnaire responses obtained from a diverse sample of participants. Objective measures defined adherence (928 of 1279 participants attended 80% or more of sessions) and compliance (867 of 1145 participants exercised 30 minutes or more each session at their prescribed heart rate). Results Prediction of attendance by self-efficacy (inversely) and self-motivation was direct and also indirect, mediated through positive relations with the typical use of behavioral change processes. Enjoyment and self-efficacy (inversely) predicted compliance with the exercise prescription. Conclusions The results support the usefulness of self-regulatory behavioral processes of the Transtheoretical Model for predicting exercise adherence, but not compliance, extending the supportive evidence for self-regulation beyond self-reports of physical activity used in prior observational studies.

To investigate the efficacy of exercise interventions on hepatic fat mobilization in non-alcoholic fatty liver disease (NAFLD) patients. Ovid-Medline, PubMed, EMBASE and Cochrane database were searched for randomized trials and prospective cohort studies in adults aged ≥ 18 which investigated the effects of at least 8 wk of exercise only or combination with diet on NAFLD from 2010 to 2016. The search terms used to identify articles, in which exercise was clearly described by type, duration, intensity and frequency were: "NASH", "NAFLD", "non-alcoholic steatohepatitis", "non-alcoholic fatty liver disease", "fat", "steatosis", "diet", "exercise", "MR spectroscopy" and "liver biopsy". NAFLD diagnosis, as well as the outcome measures, was confirmed by either hydrogen-magnetic resonance spectroscopy (H-MRS) or biopsy. Trials that included dietary interventions along with exercise were accepted if they met all criteria. Eight studies met selection criteria (6 with exercise only, 2 with diet and exercise with a total of 433 adult participants). Training interventions ranged between 8 and 48 wk in duration with a prescribed exercise frequency of 3 to 7 d per week, at intensities between 45% and 75% of VO2 peak. The most commonly used imaging modality was H-MRS and one study utilized biopsy. The effect of intervention on fat mobilization was 30.2% in the exercise only group and 49.8% in diet and exercise group. There was no difference between aerobic and resistance exercise intervention, although only one study compared the two interventions. The beneficial effects of exercise on intrahepatic triglyceride (IHTG) were seen even in the absence of significant weight loss. Although combining an exercise program with dietary interventions augmented the reduction in IHTG, as well as improved measures of glucose control and/or insulin sensitivity, exercise only significantly decreased hepatic lipid contents. Prescribed exercise in subjects with NAFLD reduces IHTG independent of

Cancer and its treatments produce lingering side-effects that undermine the quality of life (QOL) of survivors. Exercise and psycho-therapies increase QOL among survivors, however, research is needed to identify intervention characteristics most associated with such improvements. This research aimed to assess the feasibility of a 9 week individual or group based exercise and counselling program, and to examine if a group based intervention is as effective at improving the QOL of breast cancer survivors as an individual-based intervention. A three group design was implemented to compare the efficacy of a 9 week individual (IEC n = 12) and group based exercise and counselling (GEC n = 14) intervention to a usual care (UsC n = 10) group on QOL of thirty-six breast cancer survivors. Across all groups, 90% of participants completed the interventions, with no adverse effects documented. At the completion of the intervention, there was a significant difference between groups for change in global QOL across time (p group (1.8 points). The effect size was moderate (0.70). Although the GEC improved QOL by almost 10.0 points, this increase did not reach significance. Both increases were above the minimally important difference of 7-8 points. These preliminary results suggest a combined exercise and psychological counseling program is both a feasible and acceptable intervention for breast cancer survivors. Whilst both the individual and group interventions improved QOL above the clinically important difference, only the individual based intervention was significant when compared to UsC.

Constipation is a common and potentially serious side effect of oral opioids. Accordingly, most clinical guidelines suggest routine use of laxatives to prevent opioid-induced constipation. The objective was to characterize emergency provider prescribing of laxatives to prevent constipation among adults initiating outpatient opioid treatment. National Hospital Ambulatory Medical Care Survey (NHAMCS) data from 2010 were analyzed. Among visits by individuals aged 18 years and older discharged from the emergency department (ED) with opioid prescriptions, the authors estimated the survey-weighted proportion of visits in which laxatives were also prescribed. A subgroup analysis was conducted for individuals aged 65 years and older, as the potential risks associated with opioid-induced constipation are greater among older individuals. To examine a group expected to be prescribed laxative medication and confirm that NHAMCS captures prescriptions for these medications, the authors estimated the proportion of visits by individuals discharged with prescriptions for laxatives among those who presented with constipation. Among visits in 2010 by adults aged 18 years and older discharged from the ED with opioid prescriptions, 0.9% (95% confidence interval [CI] = 0.7% to 1.3%, estimated total n = 191,203 out of 21,075,050) received prescriptions for laxatives. Among the subset of visits by adults aged 65 years and older, 1.0% (95% CI = 0.5% to 2.0%, estimated total n = 18,681 out of 1,904,411) received prescriptions for laxatives. In comparison, among visits by individuals aged 18 years and older with constipation as a reason for visit, 42% received prescriptions for laxatives. In this nationally representative sample, laxatives were not routinely prescribed to adults discharged from the ED with prescriptions for opioid pain medications. Routine prescribing of laxatives for ED visits may improve the safety and effectiveness of outpatient opioid pain management. © 2015 by the

Where does HIT fit? An examination of the affective response to high-intensity intervals in comparison to continuous moderate- and continuous vigorous-intensity exercise in the exercise intensity-affect continuum.

Full Text Available Affect experienced during an exercise session is purported to predict future exercise behaviour. Compared to continuous moderate-intensity exercise (CMI, the affective response to continuous vigorous-intensity exercise (CVI has consistently been shown to be more aversive. The affective response, and overall tolerability to high-intensity interval training (HIT, is less studied. To date, there has yet to be a comparison between HIT, CVI, and CMI. The purpose of this study was to compare the tolerability and affective responses during HIT to CVI and CMI. This study utilized a repeated measures, randomized, counter-balanced design. Forty-four participants visited the laboratory on four occasions. Baseline fitness testing was conducted to establish peak power output in Watts (W peak. Three subsequent visits involved a single bout of a HIT, corresponding to 1-minute at ∼ 100% W peak and 1-minute at ∼ 20% W peak for 20 minutes, b CMI, corresponding to ∼ 40% W peak for 40 minutes, and c CVI, corresponding to ∼ 80% W peak for 20 minutes. The order of the sessions was randomized. Affective responses were measured before, during and after each session. Task self-efficacy, intentions, enjoyment and preference were measured after sessions. Participants reported greater enjoyment of HIT as compared to CMI and CVI, with over 50% of participants reporting a preference to engage in HIT as opposed to either CMI or CVI. HIT was considered more pleasurable than CVI after exercise, but less pleasurable than CMI at these times. Despite this participants reported being just as confident to engage in HIT as they were CMI, but less confident to engage in CVI. This study highlights the utility of HIT in inactive individuals, and suggests that it may be a viable alternative to traditionally prescribed continuous modalities of exercise for promoting self-efficacy and enjoyment of exercise.

Evidence based exercise - clinical benefits of high intensity interval training.

Shiraev, Tim; Barclay, Gabriella

2012-12-01

Aerobic exercise has a marked impact on cardiovascular disease risk. Benefits include improved serum lipid profiles, blood pressure and inflammatory markers as well as reduced risk of stroke, acute coronary syndrome and overall cardiovascular mortality. Most exercise programs prescribed for fat reduction involve continuous, moderate aerobic exercise, as per Australian Heart Foundation clinical guidelines. This article describes the benefits of exercise for patients with cardiovascular and metabolic disease and details the numerous benefits of high intensity interval training (HIIT) in particular. Aerobic exercise has numerous benefits for high-risk populations and such benefits, especially weight loss, are amplified with HIIT. High intensity interval training involves repeatedly exercising at a high intensity for 30 seconds to several minutes, separated by 1-5 minutes of recovery (either no or low intensity exercise). HIT is associated with increased patient compliance and improved cardiovascular and metabolic outcomes and is suitable for implementation in both healthy and 'at risk' populations. Importantly, as some types of exercise are contraindicated in certain patient populations and HIIT is a complex concept for those unfamiliar to exercise, some patients may require specific assessment or instruction before commencing a HIIT program.

Individualized feedback-based virtual reality (IFVR) exercise is gaining attention as a cost-effective self-management strategy, however little is known about whether older adults themselves perceive IFVR exercise effective in improving their health. Therefore, we studied the effect of IFVR exercise on health-related quality of life (HRQoL) in older women. Fifty-four older women aged ≥65 years were randomized to either IFVR exercise group (IFVRG, n=26) or group-based exercise group (GG, n=28). Both groups received a 60-min intervention three times a week for eight weeks. The Short-Form Health Survey (SF-36) was administered. To identify the possible placebo effect, 30-Second Chair Stand Test (30SCST), 8-Foot Up-and-Go Test (8FUGT), and 2-Minute Step Test (2MST) were also administered. intention-to-treat analysis with adjustment for baseline levels revealed that IFVRG showed greater improvement in mental health (p=0.029) and lower body strength (p=0.042), compared to GG. Within-group analysis for HRQoL revealed that IFVRG showed an increase in role-physical (p=0.015), bodily pain (p=0.017), general health (p=0.004), vitality (p=0.010), role-emotional (p=0.007), and mental health (phealth (p=0.023), and social functioning (p = 0.023). Both groups showed an increase in 30SCST, 2MST and 8FUGT (all pexercise improved HRQoL in older women, in addition to improving physical fitness.

Fernández, Cristina; Vega, José A.; Fonturbel, Teresa

2013-04-01

Prescribed burning is commonly used to reduce the risk of severe wildfire. However, further information about the associated environmental effects is required to help forest managers select the most appropriate treatment. To address this question, we evaluated if fire severity during spring prescribed burning significantly affects the resprouting ability of two common shrub species in shrubland under a Mediterranean climate in NW Spain. Fire behaviour and temperatures were recorded in tagged individuals of Erica australis and Pterospartum tridentatum during prescribed burning. The number and length of resprouted shoots were measured three times (6, 12 and 18 months) after the prescribed burning. The influence of a series of fire severity indicators on some plant resprouting vigour parameters was tested by canonical correlation analysis. Six months and one year after prescribed burning, soil burn severity (measured by the absolute reduction in depth of the organic soil layer, maximum temperatures in the organic soil layer and the mineral soil surface during burning and the post-fire depth of the organic soil layer) reduced the resprouting vigour of E. australis and P. tridentatum. In contrast, direct measurements of fire effects on plants (minimum branch diameter, duration of temperatures above 300 °C in the shrub crown and fireline intensity) did not affect the post-fire plant vigour. Soil burn severity during spring prescribed burning significantly affected the short-term resprouting vigour in a mixed heathland in Galicia. The lack of effects eighteen months after prescribed burning indicates the high resilience of these species and illustrates the need to conciliate fire prevention and conservation goals.

To investigate the relationship between smoking status and exercise capacity, physical activity in daily life and health-related quality of life in physically independent, elderly (≥60 years) individuals. 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. Tobacco exposure was associated with worse scores for the mental health dimension of SF-36 in physically independent, elderly individuals. Copyright © 2014 Chartered Society of Physiotherapy.

2016-06-01

Background and aims Recently, empirical research has linked obsessive passion to the etiology of exercise addiction, and the conceptual reason behind the fact that the latter is more prevalent in athletes than leisure exercisers has been challenged. The aim of this study was to determine the link between exercise addiction and harmonious passion, obsessive passion, and dedication to sports, in the context of athletic levels. Method A sample comprised of low- and high-level competitive athletes and non-competitive leisure exercisers (n = 313) was examined, in a cross-sectional design, in which participants completed the Spanish validated versions of the Exercise Addiction Inventory (Sicilia, Alías-García, Ferriz, & Moreno-Murcia, 2013) and Passion Scale (Chamarro et al., 2015). Results Obsessive passion and dedication to sports emerged as strong predictors of exercise addiction. Competitive athletes scored higher than leisure exercisers on all measures. Athletes competing at low and high levels only differed in dedication to their sports from each other. Team-sports athletes reported greater harmonious and obsessive passions, and dedication to sports, but not different exercise addictions, than people taking part in individual sports. Conclusions The concept of exercise addiction is not a plain and independent construct and may not reflect a psychological dysfunction in the athletic population. Athletes could interpret exercise addiction screening-items differently from non-athletes. Athletes in team sports report greater passion and dedication than those practicing individual sports.

Appropriate antibiotic prescribing is an essential strategy to reduce the spread of antibiotic resistance. US prescribing practices have not been thoroughly characterized. We analyzed outpatient antibiotic prescribing data to identify where appropriate antibiotic prescribing interventions could have the most impact. Oral antibiotic prescriptions dispensed during 2011 were extracted from the IMS Health Xponent database. The number of prescriptions and census denominators were used to calculate prescribing rates. Prescription totals were calculated for each provider specialty. Regression modeling was used to examine the association between socioeconomic and population health factors and prescribing rates. Healthcare providers prescribed 262.5 million courses of antibiotics in 2011(842 prescriptions per 1000 persons). Penicillins and macrolides were the most common antibiotic categories prescribed. The most commonly prescribed individual antibiotic agent was azithromycin. Family practitioners prescribed the most antibiotic courses (24%). The prescribing rate was higher in the South census region (931 prescriptions per 1000 persons) than in the West (647 prescriptions per 1000 persons; P 1.0). Efforts to characterize antibiotic prescribing practices should focus on the South census region and family practitioners. Further understanding of the factors leading to high prescribing among key target populations will inform appropriate prescribing interventions.

While exercising, people seem to enjoy listening to music believing that it relaxes them or helps give the necessary rhythm for exercise. But is music really beneficial? In view of different people listening to different types of music, this study was intended to assess effect of different types of music on exercise performance. 30 healthy female college students in the age group of 18 to 25 years were made to walk on the treadmill 3 times at one week interval: without music (A), with slow music (B), with fast music (C). Duration of exercise and rate of perceived exertion were recorded at the end of each session. The results showed an increase in the duration of exercise in Group B and Group C as compared to Group A and the increase was more in Group C as compared to Group B. It was observed that level of RPE was the same at the end of every exercise session. The reason for increase in exercise duration with music could be because of various factors like dissociation, arousal, motivation, etc. It can be thus suggested that exercises can be performed for longer duration with music than without music and the effect is more with fast music than with slow music. Also with music, the same level of exertion is perceived though the walking duration is considerably increased.

Full Text Available The objective of the review study was to describe the metabolic effects of resistance exercises with a potential association with lipid metabolism and thus, its possible role in the prevention of cardiovascular diseases. It was based on the literature with greater scientific relevance. The main results argue that, despite having less published studies aerobics, exercises based on the maturity of external resistors for strength training or resistance exercises, they have a positive influence on lipid metabolism, primarily hours after Have been executed. Some of the findings in healthy populations conclude that this type of exercise, in addition to an increase in muscle functional and neurophysiological properties, leads to an increase in plasma concentrations of HDL cholesterol, in addition to promoting the reduction of total cholesterol and LDL, mainly in periods postprandial. The physiological implications of resistance exercises on the activity of enzymes with a role in lipid metabolism are not conclusive. Due to the high variability in prescribing this form of exercise, more studies may elucidate the effect of different volumes, intensities and doses of lipemic variables in healthy populations or special conditions are needed.

Damon L Swift

Full Text Available Brain derived neurotrophic factor (BDNF has been implicated in memory, learning, and neurodegenerative diseases. However, the relationship of BDNF with cardiometabolic risk factors is unclear, and the effect of exercise training on BDNF has not been previously explored in individuals with type 2 diabetes.Men and women (N = 150 with type 2 diabetes were randomized to an aerobic exercise (aerobic, resistance exercise (resistance, or a combination of both (combination for 9 months. Serum BDNF levels were evaluated at baseline and follow-up from archived blood samples.Baseline serum BDNF was not associated with fitness, body composition, anthropometry, glucose control, or strength measures (all, p>0.05. Similarly, no significant change in serum BDNF levels was observed following exercise training in the aerobic (-1649.4 pg/ml, CI: -4768.9 to 1470.2, resistance (-2351.2 pg/ml, CI:-5290.7 to 588.3, or combination groups (-827.4 pg/ml, CI: -3533.3 to 1878.5 compared to the control group (-2320.0 pg/ml, CI: -5750.8 to 1110.8. However, reductions in waist circumference were directly associated with changes in serum BDNF following training (r = 0.25, p = 0.005.Serum BDNF was not associated with fitness, body composition, anthropometry, glucose control, or strength measures at baseline. Likewise, serum BDNF measures were not altered by 9 months of aerobic, resistance, or combination training. However, reductions in waist circumference were associated with decreased serum BDNF levels. Future studies should investigate the relevance of BDNF with measures of cognitive function specifically in individuals with type-2 diabetes.

Full Text Available Introduction: Exercise-induced anaphylaxis (EIA is a rare syndrome. We described two patients experienced anaphylaxis after exercise. Case 1: A 24 -year-old male patient, recruited to army as a private 6 months ago. The medical history was suggestive of an anaphylactic reaction which was developed about 30 minute after a vigorous exercise. Case 2: A 42-year old female, was referred to our clinic because of the recurrent episodes of generalized pruritus, nausea, vomiting, swelling on extremities and breathing difficultly. She was experienced with symptoms after moderate exercises which were performed to losing weight. Evaluation: The complete diagnostic procedures including skin tests with foods and inhalant allergens were performed. In Case 2, positive skin test results were detected in food allergens (apricot, tomato, vanilla and inhalant allergens (house-dust mites and cockroach. Management: In Case 1, he was first experienced EIA symptoms with the military training. For this reason, he exempted from vigorous exercises during his remaining compulsory military service and self-injectable epinephrine kit and antihistamine were prescribed him. In Case 2, she advised to avoid from vigorous exercises. Conclusion: EIA should be considered in cases of anaphylaxis with uncertain etiology. [TAF Prev Med Bull 2005; 4(1.000: 46-49

The primary objective of this study was to make the first step in the modelling of pharmaceutical demand in Italy, by deriving a weighted capitation model to account for demographic differences among general practices. The experimental model was called ASSET (Age/Sex Standardised Estimates of Treatment). Individual prescription costs and demographic data referred to 3,175,691 Italian subjects and were collected directly from three Regional Health Authorities over the 12-month period between October 2004 and September 2005. The mean annual prescription cost per individual was similar for males (196.13 euro) and females (195.12 euro). After 65 years of age, the mean prescribing costs for males were significantly higher than females. On average, costs for a 75-year-old subject would be 12 times the costs for a 25-34 year-old subject if male, 8 times if female. Subjects over 65 years of age (22% of total population) accounted for 56% of total prescribing costs. The weightings explained approximately 90% of the evolution of total prescribing costs, in spite of the pricing and reimbursement turbulences affecting Italy in the 2000-2005 period. The ASSET weightings were able to explain only about 25% of the variation in prescribing costs among individuals. If mainly idiosyncratic prescribing by general practitioners causes the unexplained variations, the introduction of capitation-based budgets would gradually move practices with high prescribing costs towards the national average. It is also possible, though, that the unexplained individual variation in prescribing costs is the result of differences in the clinical characteristics or socio-economic conditions of practice populations. If this is the case, capitation-based budgets may lead to unfair distribution of resources. The ASSET age/sex weightings should be used as a guide, not as the ultimate determinant, for an equitable allocation of prescribing resources to regional authorities and general practices.

This multistudy report used an experimental approach to alter automatic evaluations of exercise (AEE). First, we investigated the plasticity of AEE (study 1). A computerized evaluative conditioning task was developed that altered the AEE of participants in two experimental groups (acquisition of positive/negative associations involving exercising) and a control group (η2 part. = .11). Second, we examined connections between changes in AEE and subsequent exercise behavior (chosen intensity on a bike ergometer; study 2) in individuals that were placed in groups according to their baseline AEE. Group differences in exercise behavior were detected (η2 part. = .29). The effect was driven by the performance of the group with preexisting negative AEE that acquired more positive associations. This illustrates the effect of altered AEE on subsequent exercise behavior and the potential of AEE as a target for exercise intervention.

Optimal technique for deep breathing exercises after cardiac surgery.

Westerdahl, E

2015-06-01

Cardiac surgery patients often develop a restrictive pulmonary impairment and gas exchange abnormalities in the early postoperative period. Chest physiotherapy is routinely prescribed in order to reduce or prevent these complications. Besides early mobilization, positioning and shoulder girdle exercises, various breathing exercises have been implemented as a major component of postoperative care. A variety of deep breathing maneuvres are recommended to the spontaneously breathing patient to reduce atelectasis and to improve lung function in the early postoperative period. Different breathing exercises are recommended in different parts of the world, and there is no consensus about the most effective breathing technique after cardiac surgery. Arbitrary instructions are given, and recommendations on performance and duration vary between hospitals. Deep breathing exercises are a major part of this therapy, but scientific evidence for the efficacy has been lacking until recently, and there is a lack of trials describing how postoperative breathing exercises actually should be performed. The purpose of this review is to provide a brief overview of postoperative breathing exercises for patients undergoing cardiac surgery via sternotomy, and to discuss and suggest an optimal technique for the performance of deep breathing exercises.

The article of Act on Physical Protection and Radiological Emergency (APPRE) was amended as a nuclear licensee shall formulate a radiological emergency exercise plan as prescribed by the Ordinance of the Prime minister and execute such plan with the approval of the Nuclear Safety and Security Commission (NSSC). Current radiological emergency exercise is basically conducting in the field. The field exercise essentially requires participation of mass population. Due to lack of time, cost, communication and participation, the field exercise necessarily causes several limitations in an aspect of effectiveness. The public participants often misunderstood the situation as real though it is just an exercise so several conflicts are occurring. Furthermore, the exercise program is too ideal to reflect the real accident situation. In this point of view, application of virtual reality (VR) technology is highlighted with its many advantages. VR technology is expected to resolve those existing problems. Our research team is currently developing VR based radiological emergency exercise system. In this paper, the advantages and actual application of VR based training were introduced. With those advantages and improvement of existing disadvantages, our VR based radiological emergency exercise system will be developed. Not only physical interactive features, but also interactive fail-considered real-like scenarios will be adopted in the system.

Social cognitive models of health behavior propose that individual differences in leisure time exercise behavior are influenced by the attitudes towards exercise. At the same time, large scale twin-family studies show a significant influence of genetic factors on regular exercise behavior. This twin–sibling study aimed to unite these findings by demonstrating that exercise attitudes can be heritable themselves.

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

This study sought to identify factors associated with objectively assessed exercise behavior in Chinese patients with early-stage cancer. Three hundred and fifty one cancer patients were recruited from the Affiliated Jiangyin Hospital of Southeast University Medical College and the Nantong Tumor Hospital. One-way ANOVA, Pearson Chi-square tests and regression analysis were employed to identify the correlations between physical exercise and the measured factors. The results showed that occupation type (χ2 = 14.065; p = 0.029), monthly individual monthly income level (χ2 = 24.795; p = 0.003), BMI (χ2 = 15.709; p = 0.015) and diagnosis (χ2 = 42.442; p exercise with different frequency per week. Differences in the frequency of exercise were associated with different degrees of reported Benefit Finding (BF) (F = 24.651; p exercise. Our results indicated that benefit finding, medical coping modes, communication with doctors, social support, depression and quality of life were significantly correlated with exercise. The variance in several psychosocial factors (benefit finding, medical coping modes, the communication with doctors, depression and quality of life) could be explained by exercise. Psychosocial factors should be addressed and examined over time when evaluating the effect of physical exercise that is prescribed as a clinically relevant treatment.

Davis, P B; Yee, R L; Millar, J

1994-08-01

Medical practice variation is extensive and well documented, particularly for surgical interventions, and raises important questions for health policy. To date, however, little work has been carried out on interpractitioner variation in prescribing activity in the primary care setting. An analytical model of medical variation is derived from the literature and relevant indicators are identified from a study of New Zealand general practice. The data are based on nearly 9,500 completed patient encounter records drawn from over a hundred practitioners in the Waikato region of the North Island, New Zealand. The data set represents a 1% sample of all weekday general practice office encounters in the Hamilton Health District recorded over a 12-month period. Overall levels of prescribing, and the distribution of drug mentions across diagnostic groupings, are broadly comparable to results drawn from international benchmark data. A multivariate analysis is carried out on seven measures of activity in the areas of prescribing volume, script detail, and therapeutic choice. The analysis indicates that patient, practitioner and practice attributes exert little systematic influence on the prescribing task. The principal influences are diagnosis, followed by practitioner identity. The pattern of findings suggests also that the prescribing task cannot be viewed as an undifferentiated activity. It is more usefully considered as a process of decision-making in which 'core' judgements--such as the decision to prescribe and the choice of drug--are highly predictable and strongly influenced by diagnosis, while 'peripheral' features of the task--such as choosing a combination drug or prescribing generically--are less determinate and more subject to the exercise of clinical discretion.(ABSTRACT TRUNCATED AT 250 WORDS)

Effects of creatine supplementation on high-intensity intermittent exercise: discrepancies and methodological appraisals

Bruno Gualano

2008-07-01

Full Text Available http://dx.doi.org/10.5007/1980-0037.2008v10n2p189 After a brief review of the literature on the effects of creatine supplementation on high-intensity intermittent exercise performance, the main aim of this study was to discuss methodological differences between studies which could explain the discrepancies observed in the literature. The effects of creatine supplementation on high-intensity intermittent exercise performance have been investigated in depth. Although the results of much research demonstrates the effi cacy of this supplement, there is just as much evidence that does not support this ergogenic effect. The explanation for this divergence appears to be multifactorial, although it is always linked to methodological characteristics. Study design (crossover or parallel groups, individual variability of muscular creatine content, chronic high meat intake, sample size, exercise protocol characteristics (body weight dependence and time between series, and gender and age all differ between studies and are potentially the variables responsible, to differing extents, for the discrepancies observed in the literature. Studies involving young males, with parallel group design, adequate statistical power, control of the incorporation of creatine into muscles, food intake assessment and intermittent exercise protocols in which performance is independent of body weight and with rest-recovery intervals of 1 to 6 minutes, usually produce positive results. The many methodological factors which can contribute to divergence on the ergogenic effects of creatine should be considered in futures studies, as well as when prescribing creatine supplementation.

The purpose of this study was to compare the electromyographic pattern of core muscles during intermediate Pilates mat exercises between healthy people and those with low back pain. We evaluated healthy participants (n = 19; mean ± standard deviation [SD]: age 28 ± 8 years, body mass 65 ± 10 kg, height 160.0 ± 9.1 cm) and a low back pain group (n = 13; mean ± SD: age 30 ± 9 years, body mass 67 ± 12 kg, height 170.0 ± 6.6 cm). Electromyographic analysis assessed the multifidus, external oblique, internal oblique, and rectus abdominis muscles during classical Pilates exercises (single leg stretch, criss-cross, and dead bug). We calculated the root mean square normalized by maximum voluntary contraction, and the time of peak activation was provided by a linear envelope and normalized by the total movement cycle. The criss-cross exercise presented the highest values of root mean square for trunk flexors (rectus abdominis and oblique) compared with the other exercises, followed by the single leg stretch and the dead bug, which had similar muscle activation. The single leg stretch presented more activation of the rectus abdominis and oblique, whereas the criss-cross and dead bug created more activation of the oblique compared with the multifidus and rectus. The Pilates exercises presented different muscle recruitment patterns, and allowed the activation of the lumbopelvic stabilizing muscles even in the first session for healthy individuals and those with chronic low back pain.

2018-02-01

Previous reports have shown improvements in mood and increases in endocannabinoids in healthy adults following a session of aerobic exercise, but it is unclear whether adults with posttraumatic stress disorder (PTSD) experience similar responses. The purpose of this study was to examine psychobiological responses (plasma endocannabinoids [eCBs], mood, and pain) to aerobic exercise in a sample of adults with a diagnosis of PTSD (n = 12) and healthy controls (n = 12). Participants engaged in an aerobic exercise session in which they ran on a treadmill for 30 min at a moderate intensity (70 to 75% maximum heart rate [MHR]). Results indicated improvements in mood states and reductions in pain for both groups following exercise, ds = 0.19 to 1.53. Circulating concentrations of N-arachidonylethanolamine (AEA), 2-arachidonoylglycerol (2-AG), and oleoylethanolamide (OEA) significantly increased (ps = .000 to .050) following the aerobic exercise session for both groups. There were no significant time, group, or interaction effects (ps = .062 to .846) for palmitoylethanolamide (PEA) and 2-oleoylglycerol (2-OG). Although eCBs increased significantly for both groups, within-group effect size calculations indicated the healthy controls experienced a greater magnitude of change for AEA when compared with adults with PTSD, d = 1.21 and d = 0.45, respectively; as well as for 2-AG, d = 0.43 and d = 0.21, respectively. The findings from this study indicated that adults with and without PTSD reported significant mood improvements following 30 min of moderate-intensity aerobic exercise. In addition, the endocannabinoid system was activated in adults with and without PTSD, although effect sizes suggest that adults with PTSD may have a blunted endocannabinoid response to exercise.

Full Text Available Diabetes is a crucial health problem due to its incidence and serious complications. Physical inactivity is one of the risk factors associated with it. Therapeutic exercises are beneficial in the treatment and prevention of diabetes. There are several studies about the effects of exercise type and intensity on glycemic control. The exercise programs should be prepared individually after a comprehensive medical evaluation. There are some regulations to prevent acute complications before, after and during the exercises. The importance of regular exercise for public health should be pointed out and physical activity should be urged. The present review discusses issues concerning the prevention and treatment of diabetes through exercise, and the possible risks, in view of current literature.

Cycling above rather than below lactate threshold is more effective for nitric oxide release and post-exercise blood pressure reduction in individuals with type-2 diabetes

Full Text Available The purposes of this study were to analyze and compare the effects of exercise performed in different intensities, above and below lactate threshold (LT on post-exercise blood pressure (BP and nitric oxide (NO responses in individuals with type 2 diabetes (T2D. For this, 11 T2D underwent the following sessions: 1 control session; 2 20-min of moderate cycling (80% LT; and 3 20-min of high intensity cycling (120%LT on a cycle ergometer. Plasma NO and BP measurements were carried out at rest and at 15 and 45 min of post-sessions. When compared to rest, only the exercise session performed at 120%LT elicited an increase of NO (from 7.2 to 9.5 µM, p<0.05, as well as a decrease in systolic BP (from 126.6±7.9 to 118.7±3.9 mmHg, p<0.05 during the post-exercise period. In conclusion, the results suggest that NO release and post-exercise BP decrease are intensity-dependent for individuals with T2D.

Consequences of objective self-awareness during exercise

Full Text Available Although exercise is recommended by healthcare professionals for nearly everyone, adverse reactions can occur following exercising for some overweight individuals. The reported study investigated the cardiovascular consequences of exercise in a stressful environment. In all, 60 females completed two baseline and one biking (i.e. ergometer periods while cardiovascular and self-report measures were recorded. Findings indicated that those who are more self-aware showed cardiovascular response patterns indicative of threat. Additionally, post-task exercise self-efficacy levels predicted intentions to exercise at a demanding level in the coming week. These findings suggest exercise may exacerbate health issues for some individuals for whom it is recommended.

Why don't you exercise? Development of the Amotivation Toward Exercise Scale among older inactive individuals.

Vlachopoulos, Symeon P; Gigoudi, Maria A

2008-07-01

This article reports on the development and initial validation of the Amotivation Toward Exercise Scale (ATES), which reflects a taxonomy of older adults' reasons to refrain from exercise. Drawing on work by Pelletier, Dion, Tuson, and Green-Demers (1999) and Legault, Green-Demers, and Pelletier (2006), these dimensions were the outcome beliefs, capacity beliefs, effort beliefs, and value amotivation beliefs toward exercise. The results supported a 4-factor correlated model that fit the data better than either a unidimensional model or a 4-factor uncorrelated model or a hierarchical model with strong internal reliability for all the subscales. Evidence also emerged for the discriminant validity of the subscale scores. Furthermore, the predictive validity of the subscale scores was supported, and satisfactory measurement invariance was demonstrated across the calibration and validation samples, supporting the generalizability of the scale's measurement properties.

The objectives of this study were: 1) to establish criteria for evaluating handheld computerized prescribing systems; and 2) to evaluate out-of-box performance and features of a new, Palm Operating System (OS)-based, handheld, wireless wide area network (WWAN) prescribing system. The system consisted of a Palm Vx handheld organizer, a Novatel Minstrel V wireless modem, OmniSky wireless internet access and ePhysician ePad 1.1, the Palm OS electronic prescribing software program. A dermatologist familiar with healthcare information technology conducted an evaluation of the performance and features of a new, handheld, WWAN electronic prescribing system in an office practice during a three-month period in 2000. System performance, defined as transmission success rate, was determined from data collected during the three-month trial. Evaluation criteria consisted of an analysis of features found in electronic prescribing systems. All prescriptions written for all patients seen during a three-month period (August - November, 2000) were eligible for inclusion. Prescriptions written for patients who intended to fill them at pharmacies without known facsimile receiving capabilities were excluded from the study. The performance of the system was evaluated using data collected during the study. Criteria for evaluating features of electronic prescribing systems were developed and used to analyze the system employed in this study. During this three-month trial, 200 electronic prescriptions were generated for 132 patients included in the study. Of these prescriptions, 92.5 percent were successfully transmitted to pharmacies. Transmission failures resulted from incorrect facsimile numbers and non-functioning facsimile machines.

Rizzo, Jon

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.

Inappropriate prescribing: criteria, detection and prevention.

LENUS (Irish Health Repository)

O'Connor, Marie N

2012-06-01

Inappropriate prescribing is highly prevalent in older people and is a major healthcare concern because of its association with negative healthcare outcomes including adverse drug events, related morbidity and hospitalization. With changing population demographics resulting in increasing proportions of older people worldwide, improving the quality and safety of prescribing in older people poses a global challenge. To date a number of different strategies have been used to identify potentially inappropriate prescribing in older people. Over the last two decades, a number of criteria have been published to assist prescribers in detecting inappropriate prescribing, the majority of which have been explicit sets of criteria, though some are implicit. The majority of these prescribing indicators pertain to overprescribing and misprescribing, with only a minority focussing on the underprescribing of indicated medicines. Additional interventions to optimize prescribing in older people include comprehensive geriatric assessment, clinical pharmacist review, and education of prescribers as well as computerized prescribing with clinical decision support systems. In this review, we describe the inappropriate prescribing detection tools or criteria most frequently cited in the literature and examine their role in preventing inappropriate prescribing and other related healthcare outcomes. We also discuss other measures commonly used in the detection and prevention of inappropriate prescribing in older people and the evidence supporting their use and their application in everyday clinical practice.

High-intensity exercise training for the prevention of type 2 diabetes mellitus.

Rynders, Corey A; Weltman, Arthur

2014-02-01

Aerobic exercise training and diet are recommended for the primary prevention of type 2 diabetes mellitus and cardiovascular disease. The American Diabetes Association (ADA) recommends that adults with prediabetes engage in ≥ 150 minutes per week of moderate activity and target a 7% weight loss. However, traditional moderate-intensity (MI) exercise training programs are often difficult to sustain for prediabetic adults; a commonly cited barrier to physical activity in this population is the "lack of time" to exercise. When matched for total energy expenditure, high-intensity (HI) exercise training has a lower overall time commitment compared with traditional low-intensity (LI) or MI exercise training. Several recent studies comparing HI exercise training with LI and MI exercise training reported that HI exercise training improves skeletal muscle metabolic control and cardiovascular function in a comparable and/or superior way relative to LI and MI exercise training. Although patients can accrue all exercise benefits by performing LI or MI activities such as walking, HI activities represent a time-efficient alternative to meeting physical activity guidelines. High-intensity exercise training is a potent tool for improving cardiometabolic risk for prediabetic patients with limited time and may be prescribed when appropriate.

Ensuring appropriate prescribing is an important challenge for the health service, and the need for research that takes account of the reasons behind individual general practitioners' (GPs) prescribing decisions has been highlighted. To explore differences among GPs in their decisions to prescribe new drugs. Qualitative approach, using in-depth semistructured interviews. Northern and Yorkshire Health Authority Region. Participants were identified from a random sample of 520 GPs in a quantitative study of patterns of uptake of eight recently introduced drugs. Purposeful sampling ensured inclusion of GPs prescribing any of the eight drugs and working in a range of practice settings. Fifty-six GPs were interviewed, using a topic guide. Interviews were recorded on audiotape. Transcribed text was methodically coded and data were analysed by constantly comparing emerging themes. Both low and high prescribers shared a view of themselves as conservative in their prescribing behaviour. Low prescribers appeared to conform more strongly to group norms and identified a consensus among practice partners in prescribing and cost-consciousness. Conformism to group norms was represented by a commitment to practice formularies. High prescribers more often expressed themselves to be indifferent to drug costs and a shared practice ethos. A shift in the attitudes of some GPs is required before cost-effectiveness is routinely incorporated in drug prescribing. The promotion of rational prescribing is likely to be more successful if efforts are focused on GPs' appreciation of cost issues and attitudes towards shared decision-making and responsibility.

Should ovulation be induced in women recovering from an eating disorder or who are compulsive exercisers?

1990-03-01

The eating and exercise history of women with secondary amenorrhea and failure of ovulation using CC was studied in 14 consecutive women on a GnRH-a program. All had a history of an eating or exercise disorder. At the time of the interview, 7 women continued to have an eating or exercise disorder. There were 15 pregnancies (12 women) with 12 live births, of which 4 weighed less than 2,500 g. Infertility specialists should inquire routinely about a woman's body weight and eating and exercise behaviors, and consider treatment for these before prescribing drugs to induce ovulation.

The role of exercise dependence for the relationship between exercise behavior and eating pathology: mediator or moderator?

Science.gov (United States)

Cook, Brian J; Hausenblas, Heather A

2008-05-01

Our study examined the potential mediating or moderating effect of exercise dependence on the exercise-eating pathology relationship. Female university students (N = 330) completed Internet-based self-report measures of exercise behavior, exercise dependence, and eating pathology. Exercise dependence served as a mediator for the relationship between exercise and eating pathology. This unidirectional causal model suggests that an individual's pathological motivation or compulsion to exercise is the critical mediating component in the exercise-eating pathology relationship. The best target for removing the link between exercise behavior and eating pathology may be reformulating exercise dependence symptoms.

Previous research has identified exercise identity and social physique anxiety as two independent factors that are associated with exercise dependence. The purpose of our study was to investigate the unique and interactive effect of these two known correlates of exercise dependence in a sample of 1,766 female runners. Regression analyses tested the main effects of exercise identity and social physique anxiety on exercise dependence. An interaction term was calculated to examine the potential moderating effect of social physique anxiety on the exercise identity and exercise dependence relationship. Results indicate a main effect for exercise identity and social physique anxiety on exercise dependence; and the interaction of these factors explained exercise dependence scores beyond the independent effects. Thus, social physique anxiety acted as a moderator in the exercise identity and exercise dependence relationship. Our results indicate that individuals who strongly identify themselves as an exerciser and also endorse a high degree of social physique anxiety may be at risk for developing exercise dependence. Our study supports previous research which has examined factors that may contribute to the development of exercise dependence and also suggests a previously unknown moderating relationship for social physique anxiety on exercise dependence.

Therapeutic exercises for the control of temporomandibular disorders

Directory of Open Access Journals (Sweden)

Alberto da Rocha Moraes

2013-10-01

Full Text Available INTRODUCTION: Temporomandibular disorder (TMD is a multifactorial disease. For this reason, it is difficult to obtain an accurate and correct diagnosis. In this context, conservative treatments, including therapeutic exercises classified as stretching, relaxation, coordination, strengthening and endurance, are oftentimes prescribed. OBJECTIVE: Thus, the aim of the present article was to conduct a literature review concerning the types of exercises available and the efficacy for the treatment of muscular TMD. METHODS: The review included researches carried out between 2000 and 2010, indexed on Web of Science, PubMed, LILACS and BBO. Moreover, the following keywords were used: Exercise, physical therapy, facial pain, myofascial pain syndrome, and temporomandibular joint dysfunction syndrome. Studies that did not consider the subject "TMD and exercises", used post-surgery exercises and did not use validated criteria for the diagnosis of TMD (RDC/TMD were not included. RESULTS: The results comprised seven articles which proved therapeutic exercises to be effective for the treatment of muscular TMD. However, these studies are seen as limited, since therapeutic exercises were not applied alone, but in association with other conservative procedures. In addition, they present some drawbacks such as: Small samples, lack of control group and no detailed exercise description which should have included intensity, repetition, frequency and duration. CONCLUSION: Although therapeutic exercises are considered effective in the management of muscular TMD, the development of randomized clinical trials is necessary, since many existing studies are still based on the clinical experience of professionals.

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.

Biases in medication prescribing: the case of second-generation antipsychotics.

Science.gov (United States)

Makhinson, Michael

2010-01-01

The shift from first-generation antipsychotic medications to second-generation antipsychotic medications initially caused a wave of excitement about the potential for improved and broader efficacy of these medications concurrent with an improved side-effect profile. Recent data from high-quality research analyses have subsequently raised significant questions about these claims. This research evidence has, however, not altered prescribing behavior in a way that would be expected from fully rational evaluation of the evidence. Prescribing decisions represent poorly understood, complex behaviors influenced by a number of external and internal forces, some of which may be elucidated by advances in social and cognitive psychology. In this article, the decision to prescribe first- versus second-generation antipsychotic medications is examined, and specific social psychological biases and individual cognitive biases are hypothesized to be significant influences on clinicians. These biases may perpetuate disparity between research evidence and clinical practice.

We aimed to examine the effects of various leisure activities on cognitive impairment in young-old (aged 65-74 years) and old-old (aged ≥ 75 years) adults. In total, 10,279 elderly Korean individuals from the 2014 Korean National Survey on Older Adults' cohort were enrolled in our study. Cognitive impairment was assessed using the standardized score of the Mini-Mental State Examination for Dementia Screening, whereas leisure activities were recorded via self-reporting of the extent and type of leisure activity the subjects involved in over the past year. Multivariate logistic regression was used to assess the effect of leisure activities on cognitive impairment, while controlling for potential covariates. The subjects were more likely to participate in cognitive activities than in non-exercise physical activities. After controlling for selected covariates, involvement in cognitive activities was found to be a significant predictor of cognitive impairment in both the groups, whereas involvement in non-exercise physical activities was not a predictor of cognitive impairment in individuals aged ≥ 75 years. Moreover, depressive symptoms, rural residence, and hearing difficulties were common predictors of cognitive impairment among elderly-Korean-individuals. Leisure activity involvement may help delay cognitive impairment, which is often concomitant with aging. Hence, an early intervention service may significantly benefit both young-old and old-old individuals.

Exercisers' perceptions of their fitness instructor's interacting style, perceived competence, and autonomy as a function of self-determined regulation to exercise, enjoyment, affect, and exercise frequency.

Puente, Rogelio; Anshel, Mark H

2010-02-01

The primary purpose of the present investigation was to test the hypothesis, derived from Self-Determination Theory (SDT), that an individual's perceived competence and autonomy mediate the relationship between the exercisers' perception of their instructor's interaction style and the exercisers' motivation to exercise. A secondary purpose was to identify the affective and behavioral outcomes derived from self-determined regulation. It was hypothesized that SDT would significantly explain and predict exercise behavior. Participants consisted of 238 college students, 103 males and 135 females (M age = 20.4 years, SD = 2.16), who volunteered to participate in the study. They were asked to complete a battery of questionnaires measuring instructor's interacting style, self-regulation to exercise, perceived autonomy and competence, enjoyment, positive and negative affect, and exercise frequency. Using structural equation modeling with observed variables, the results showed that perceived competence and autonomy mediated the relationship between perceived instructor's interacting style and self-determined regulation. It was also found that self-determined regulation was significantly related to exercise enjoyment, positive affect, and exercise frequency. It was concluded that understanding the motivational factors and emotional and behavioral consequences of physical activity will partially explain an individual's motives to engage regularly in exercise.

Mundell, Niamh L; Daly, Robin M; Macpherson, Helen; Fraser, Steve F

2017-04-01

Androgen deprivation therapy (ADT) is an effective and widely prescribed treatment for prostate cancer (PCa), but it is associated with multiple treatment-induced adverse effects that impact on various musculoskeletal and cardiometabolic health outcomes. Emerging research has shown that ADT is also associated with cognitive impairment, which has been linked to a loss of independence, increased falls and fracture risk and greater use of medical services. The aim of this review is to outline the evidence related to the effect of ADT use on cognitive function, and propose a role for exercise training as part of usual care to prevent and/or manage cognitive impairments for PCa survivors on ADT. The following results have been obtained from this study. ADT has been shown to adversely affect specific cognitive domains, particularly verbal memory, visuomotor function, attention and executive function. However, current clinical guidelines do not recommend routine assessment of cognitive function in these men. No studies have examined whether exercise training can preserve or improve cognitive function in these men, but in healthy adults', multimodal exercise training incorporating aerobic training, progressive resistance training (PRT) and challenging motor control exercises have the potential to attenuate cognitive decline. In conclusion, as treatment with ADT for men with PCa has been associated with a decline in cognition, it is recommended that cognitive function be routinely monitored in these men and that regular exercise training be prescribed to preserve (or improve) cognitive function. Assessment of cognition and individualised exercise training should be considered in the usual treatment plan of PCa patients receiving ADT. © 2017 Society for Endocrinology.

2017-08-01

Patients with human papillomavirus (HPV)-related head and neck cancer (HNC) have a better prognosis relative to other types of HNC, making survivorship an emerging and critical issue. Exercise is a core component of survivorship care, but little is known about how many survivors of HPV-related HNC can safely be advised to start exercising on their own, as opposed to needing further evaluation or supervised exercise. We utilized guidelines to identify health issues that would indicate value of further evaluation prior to being safely prescribed unsupervised exercise. We performed a retrospective chart review of 150 patients with HPV-related HNC to assess health issues 6 months after completing definitive therapy. Patients with at least one health issue were deemed appropriate to receive further evaluation prior to prescription for unsupervised exercise. We utilized logistic regression to identify clinical and demographic factors associated with the need for further evaluation, likely performed by outpatient rehabilitation clinicians. In this cohort of patients, 39.3% could safely be prescribed unsupervised exercise 6 months after completing definitive therapy. On multivariable regression, older age, BMI >30, and receipt of radiation were associated with an increased likelihood for requiring further evaluation or supervised exercise. Over half of patients with HPV-related HNC would benefit from referral to physical therapy or an exercise professional for further evaluation to determine the most appropriate level of exercise supervision, based upon current guidelines. Development of such referral systems will be essential to enhance survivorship outcomes for patients who have completed treatment.

Acute effects of beta blockade and exercise on mood and anxiety.

To measure the previously reported beta blocker induced adverse changes in mood state and anxiety measures, and to determine if prolonged aerobic exercise attenuates such mood modifications. After 4 days of drug treatment with comparable doses of propranolol (40 and 80 mg), metoprolol (50 and 100 mg), or placebo, mood (POMS) and anxiety states (STAI) were assessed in healthy volunteers, before and after 1 h of treadmill walking exercise at 50% maximum oxygen uptake. Compared to placebo, resting "tension", "depression", and "total mood disturbance" were significantly higher on propranolol 80 mg, but all were reduced with exercise. "Fatigue" and "confusion" were also higher on propranolol, and were unaffected by exercise. "Fatigue" was also higher than placebo after exercise on metoprolol 100 mg. "Anxiety" was unaffected by drug treatment or exercise. The evidence that beta blockers, and particularly propranolol, have adverse effects on mood was confirmed. It would be preferable to prescribe a beta blocker which does not adversely alter mood states. However, exercise significantly reduced the measures of "tension" and "depression" which were adversely increased by propranolol. Exercise prescription may therefore not only be compatible with beta blockade, but a highly desirable adjuvant therapy.

Acute and chronic effects of resistance exercise on the testosterone and cortisol responses in obese males: a systematic review.

Science.gov (United States)

O'Leary, C B; Hackney, A C

2014-01-01

The biosynthesis and metabolism of testosterone and cortisol are altered by the high levels of adipose tissue and the constant state of low-grade inflammation of obesity. Resistance exercise (REx) has become one of the main lifestyle interventions prescribed to obese individuals due to its ability to positively influence body composition and some biomarkers, such as cholesterol and insulin resistance. Yet, little research has been done in obese examining the effects of REx on the testosterone and blood cortisol responses, two integral hormones in both exercise and obesity. The obese testosterone response to REx and whether or not it is blunted compared to lean individuals remains elusive. Conflicting findings concerning the blood cortisol response have also been reported, likely due to variance in REx protocol and the level of obesity in the participants in studies. Comparatively, both of these hormones have been extremely well studied in untrained lean males, which could be used as a basis for future research in obese males. However, without this endocrinological information, it is unknown if the current acute REx prescriptions are appropriate for eliciting a favorable acute endocrinological response, and ultimately, a positive chronic adaptation in obese males.

Full Text Available Individuals with Substance Use Disorder (SUD have lower baseline metabolic activity of the prefrontal cortex (PFC associated with impairment of cognitive functions in decision-making and inhibitory control. Aerobic exercise has shown to improve PFC function and cognitive performance, however, its effects on SUD individuals remain unclear.To verify the cognitive performance and oxygenation of the PFC during an incremental exercise in SUD individuals.Fourteen individuals under SUD treatment performed a maximum graded exercise test on a cycle ergometer with continuous measurements of oxygen consumption, PFC oxygenation, and inhibitory control (Stroop test every two minutes of exercise at different intensities. Fifteen non-SUD individuals performed the same protocol and were used as control group.Exercise increased oxyhemoglobin (O2Hb and total hemoglobin (tHb by 9% and 7%, respectively. However, when compared to a non-SUD group, this increase was lower at high intensities (p<0.001, and the inhibitory cognitive control was lower at rest and during exercise (p<0.007. In addition, PFC hemodynamics during exercise was inversely correlated with inhibitory cognitive performance (reaction time (r = -0.62, p = 0.001, and a lower craving perception for the specific abused substance (p = 0.0189 was reported immediately after exercise.Despite SUD individuals having their PFC cerebral oxygenation increased during exercise, they presented lower cognition and oxygenation when compared to controls, especially at elevated intensities. These results may reinforce the role of exercise as an adjuvant treatment to improve PFC function and cognitive control in individuals with SUD.

The study aims to evaluate the effects of the order of endurance and resistance exercises on postexercise blood pressure (BP) and hemodynamics in hypertensive women. Nineteen hypertensive women underwent 3 sessions: control (50 minutes rest), endurance (50-60% of heart rate reserve) followed by resistance exercise (50% of 1 repetition maximum) (E + R), and resistance followed by endurance exercise (R + E). Before and 30 minutes after each session, BP, peripheral vascular resistance, cardiac output, stroke volume, and heart rate were measured. Postexercise increases in systolic (E + R: +1 ± 3 mm Hg and R + E: +3 ± 3 mm Hg), diastolic (E + R: +3 ± 1 mm Hg and R + E: +3 ± 2 mm Hg), and mean BP (E + R: +3 ± 1 mm Hg and R + E: +3 ± 2 mm Hg) were significantly lower after the exercise sessions compared with the control session (p ≤ 0.05). The exercise sessions abolished the increases in peripheral vascular resistance (E + R: +0.00 ± 0.04 mm Hg·min·L and R + E: +0.05 ± 0.05 mm Hg·min·L) and the decreases in cardiac output (E + R: +0.04 ± 0.28 L·min and R + E: -0.26 ± 0.28 L·min) observed after the control session (p ≤ 0.05). After the exercise sessions, stroke volume decreased (E + R: -14 ± 3 ml and R + E: -9 ± 4 ml) and heart rate increased (E + R: +5 ± 1 b·min and R + E: +4 ± 1 b·min) in comparison with the control session (p ≤ 0.05). For all the variables, there were no significant differences between the exercise sessions. Regardless of the order of endurance and resistance exercises, combined exercise sessions abolished increases in BP observed in a control condition due to a reduction in peripheral vascular resistance and increases in cardiac output. Thus, combined exercises should be prescribed to individuals with hypertension to control their BP, regardless of the order they are accomplished.

To compare rates of dental opioid prescribing between periods of full and partial integration of pharmacy services and periods of no integration. This observational study used a retrospective chart review of opioid prescriptions written by dental providers practicing in a free dental clinic for the medically underserved over a period of 74 months. Pharmacy services were fully integrated into the practice model for 48 of the 74 months under study. During this time frame, all dental opioid orders required review by the pharmacy department before prescribing. Outcomes related to prescribing rates and errors were compared between groups, which were defined by the level of integrated pharmacy services. Demographic and prescription-specific data (drug name, dose, quantity, directions, professional designation of individual entering order) and clinic appointment data were collected and analyzed with the use of descriptive and inferential statistics. A total of 102 opioids were prescribed to 89 patients; hydrocodone-acetaminophen combination products were the most frequently used. Opioid prescribing rates were 5 times greater when pharmacy services were not integrated (P dental practice. Copyright © 2017 American Pharmacists Association®. Published by Elsevier Inc.

With prescribing expenditure rising and evidence of prescribing costs variation, general practitioners (GPs) in the UK are under increasing pressure to contain spending. The introduction of cash-limited, unified budgets and increased monitoring of prescribing within Primary Care Organizations (PCO) are intended to increase efficiency and enhance GPs financial responsibility. Whilst GPs regularly receive data on the costs of their prescribing and also performance against a set prescribing budget, little is known about the extent to which GPs take cost into account in their prescribing decisions. This study undertook a qualitative exploration of the attitudes of various stakeholders on the relative importance and influence of cost on general practice prescribing. In order to explore a plurality of perspectives, data were obtained from focus groups and a series of individual semi-structured interviews with GPs and key PCO stakeholders. The data suggest that although almost all GPs believed costs should be taken into account when prescribing, there was great variation in the extent to which this was applied and to how sensitive GPs were to costs. Cost was secondary to clinical effectiveness and safety, whilst individual patient need was emphasized above other forms of rationality or notions of opportunity costs. Conflict was apparent between a PCO policy of cost-containment and GPs' resistance to cost-cutting. GPs largely applied simple cost-minimization while cost-consideration was undermined by contextual factors. Implications for research and policy are discussed.

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) involv...

Type 1 diabetes is a challenging condition to manage for various physiological and behavioural reasons. Regular exercise is important, but management of different forms of physical activity is particularly difficult for both the individual with type 1 diabetes and the health-care provider. People with type 1 diabetes tend to be at least as inactive as the general population, with a large percentage of individuals not maintaining a healthy body mass nor achieving the minimum amount of moderate to vigorous aerobic activity per week. Regular exercise can improve health and wellbeing, and can help individuals to achieve their target lipid profile, body composition, and fitness and glycaemic goals. However, several additional barriers to exercise can exist for a person with diabetes, including fear of hypoglycaemia, loss of glycaemic control, and inadequate knowledge around exercise management. This Review provides an up-to-date consensus on exercise management for individuals with type 1 diabetes who exercise regularly, including glucose targets for safe and effective exercise, and nutritional and insulin dose adjustments to protect against exercise-related glucose excursions.

Resistance exercise intensity is commonly prescribed as a percent of 1 repetition maximum (1RM). However, the relationship between percent 1RM and the number of repetitions allowed remains poorly studied, especially using free weight exercises. The purpose of this study was to determine the maximal number of repetitions that trained (T) and untrained (UT) men can perform during free weight exercises at various percentages of 1RM. Eight T and 8 UT men were tested for 1RM strength. Then, subjects performed 1 set to failure at 60, 80, and 90% of 1RM in the back squat, bench press, and arm curl in a randomized, balanced design. There was a significant (p squat than the bench press or arm curl at 60% 1RM for T and UT. At 80 and 90% 1RM, there were significant differences between the back squat and other exercises; however, differences were much less pronounced. No differences in number of repetitions performed at a given exercise intensity were noted between T and UT (except during bench press at 90% 1RM). In conclusion, the number of repetitions performed at a given percent of 1RM is influenced by the amount of muscle mass used during the exercise, as more repetitions can be performed during the back squat than either the bench press or arm curl. Training status of the individual has a minimal impact on the number of repetitions performed at relative exercise intensity.

[Purpose] The purpose of this study was to document the effect of individual strengthening exercises for posterior pelvic tilt muscles on back pain, pelvic tilt angle, and lumbar ROM of a low back pain (LBP) patient with excessive lordosis. [Subjects] The subject was a 28 year-old male with excessive lordosis who complained of severe LBP at the L3 level. [Methods] He performed individual strengthening exercises for the posterior pelvic tilt muscles (rectus abdominis, gluteus maximus, hamstring). [Results] Pelvic tilt angles on the right and left sides recovered to his normal ranges. Limited lumbar ROM increased, and low back pain decreased. [Conclusion] We suggest that an approach of individual resistance exercises is necessary for the effective and fast strengthening of the pelvic posterior tilt muscles in case of LBP with excessive lordosis.

Full Text Available Abstract Background The United States (US Health Information Technology for Economic and Clinical Health Act of 2009 has spurred adoption of electronic health records. The corresponding meaningful use criteria proposed by the Centers for Medicare and Medicaid Services mandates use of computerized provider order entry (CPOE systems. Yet, adoption in the US and other Western countries is low and descriptions of successful implementations are primarily from the inpatient setting; less frequently the ambulatory setting. We describe prescriber and staff perceptions of implementation of a CPOE system for medications (electronic- or e-prescribing system in the ambulatory setting. Methods Using a cross-sectional study design, we conducted eight focus groups at three primary care sites in an independent medical group. Each site represented a unique stage of e-prescribing implementation - pre/transition/post. We used a theoretically based, semi-structured questionnaire to elicit physician (n = 17 and staff (n = 53 perceptions of implementation of the e-prescribing system. We conducted a thematic analysis of focus group discussions using formal qualitative analytic techniques (i.e. deductive framework and grounded theory. Two coders independently coded to theoretical saturation and resolved discrepancies through discussions. Results Ten themes emerged that describe perceptions of e-prescribing implementation: 1 improved availability of clinical information resulted in prescribing efficiencies and more coordinated care; 2 improved documentation resulted in safer care; 3 efficiencies were gained by using fewer paper charts; 4 organizational support facilitated adoption; 5 transition required time; resulted in workload shift to staff; 6 hardware configurations and network stability were important in facilitating workflow; 7 e-prescribing was time-neutral or time-saving; 8 changes in patient interactions enhanced patient care but required education; 9 pharmacy

Safe prescribing: a titanic challenge

Science.gov (United States)

Routledge, Philip A

2012-01-01

The challenge to achieve safe prescribing merits the adjective ‘titanic’. The organisational and human errors leading to poor prescribing (e.g. underprescribing, overprescribing, misprescribing or medication errors) have parallels in the organisational and human errors that led to the loss of the Titanic 100 years ago this year. Prescribing can be adversely affected by communication failures, critical conditions, complacency, corner cutting, callowness and a lack of courage of conviction, all of which were also factors leading to the Titanic tragedy. These issues need to be addressed by a commitment to excellence, the final component of the ‘Seven C's’. Optimal prescribing is dependent upon close communication and collaborative working between highly trained health professionals, whose role is to ensure maximum clinical effectiveness, whilst also protecting their patients from avoidable harm. Since humans are prone to error, and the environments in which they work are imperfect, it is not surprising that medication errors are common, occurring more often during the prescribing stage than during dispensing or administration. A commitment to excellence in prescribing includes a continued focus on lifelong learning (including interprofessional learning) in pharmacology and therapeutics. This should be accompanied by improvements in the clinical working environment of prescribers, and the encouragement of a strong safety culture (including reporting of adverse incidents as well as suspected adverse drug reactions whenever appropriate). Finally, members of the clinical team must be prepared to challenge each other, when necessary, to ensure that prescribing combines the highest likelihood of benefit with the lowest potential for harm.

Shields, Christopher A; Brawley, Lawrence R

2007-07-01

We examined the influence of proxy-assistance on exercisers' social cognitions and behavior. Fifty-six fitness class participants reported preference for proxy-assistance and reacted to exercising in different contexts. A 2 (proxy-led vs self-managed exercise context) by 2 (preferred assistance) MANOVA revealed significant assistance by context interactions for self-regulatory efficacy (SRE) and difficulty. Regarding self-managed exercise, high-assistance individuals expressed lower SRE and higher difficulty. Chi-square analysis revealed that significantly fewer high-assistance participants chose self-managed exercise. A one-way MANOVA on preferred assistance indicated that high-assistance participants were less confident, satisfied and perceived their self-managed exercise as more difficult. Results support Bandura's theorizing that use of a proxy can limit SRE of those preferring the proxy's control of their behavior.

Neuropharmacology and mental health nurse prescribers.

2006-08-01

To outline the development and content of a 'top-up' neuropharmacology module for mental health nurse prescribers and consider how much pharmacology training is required to ensure effective mental health prescribing practice. Debate about the content of prescribing training courses has persisted within the United Kingdom since the mid-1980s. In early 2003 supplementary prescribing was introduced and gave mental health nurses the opportunity to become prescribers. The challenge of the nurse prescribing curriculum for universities is that they have only a short time to provide nurses from a range of backgrounds with enough knowledge to ensure that they meet agreed levels of competency for safe prescribing. There is growing concern within mental health care that the prescribing of medication in mental health services falls short of what would be deemed good practice. Over the past two decades, nurse training has increasingly adopted a psychosocial approach to nursing care raising concerns that, although nurses attending prescribing training may be able to communicate effectively with service users, they may lack the basic knowledge of biology and pharmacology to make effective decisions about medication. Following the completion of a general nurse prescribing course, mental health nurses who attended were asked to identify their specific needs during the evaluation phase. Although they had covered basic pharmacological principles in their training, they stated that they needed more specific information about drugs used in mental health; particularly how to select appropriate drug treatments for mental health conditions. This paper describes how the nurses were involved in the design of a specific module which would enable them to transfer their theoretical leaning to practice and in so doing increase their confidence in their new roles. The findings of this study suggest that the understanding and confidence of mental health nurse prescribers about the drugs they

Exercise addiction.

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.

Individuals show high variability in body weight responses to exercise training. Expectations and motivation towards effects of exercise on body weight might influence eating behaviour and could conceal regulatory mechanisms. We conducted 2 single-blind exercise trials (4 weeks (study 1) and 8 weeks (study 2)) with concealed objectives and exclusion of individuals with weight loss intention. Circuit exercise training programs (3 times a week (45-90 min), intensity 50%-90% peak oxygen uptake for 4 and 8 weeks) were conducted. Thirty-four females finished the 4-week intervention and 36 females the 8-week intervention. Overweight/obese (OV/OB) and lean female participants' weight/body composition responses were assessed and fasting and postprandial appetite hormone levels (PYY, insulin, amylin, leptin, ghrelin) were measured before and after the intervention for understanding potential contribution to individuals' body weight response to exercise training (study 2). Exercise training in both studies did not lead to a significant reduction of weight/body mass index (BMI) in the participants' groups; however, lean participants gained muscle mass. Appetite hormones levels were significantly (p training did not lead to weight loss in female participants, while a considerable proportion of variance in body weight response to training could be explained by individuals' appetite hormone levels and BMI.

Chronic Achilles tendinopathy (AT) is an overuse condition seen among runners. Eccentric exercise can decrease pain and improve function for those with chronic degenerative tendon changes; however, some individuals have continued pain requiring additional intervention. While joint mobilization and manipulation has not been studied in the management in Achilles tendinopathy, other chronic tendon dysfunction, such as lateral epicondylalgia, has responded well to manual therapy (MT). Three runners were seen in physical therapy (PT) for chronic AT. They were prescribed eccentric loading exercises and calf stretching. Joint mobilization and manipulation was implemented to improve foot and ankle mobility, decrease pain, and improve function. Immediate within-session changes in pain, heel raise repetitions, and pressure pain thresholds (PPT) were noted following joint-directed MT in each patient. Each patient improved in self-reported function on the Achilles tendon specific Victorian Institute for Sport Assessment questionnaire (VISA-A), pain levels, PPT, joint mobility, ankle motion, and single-leg heel raises at discharge and 9-month follow-up. The addition of MT directed at local and remote sites may enhance the rehabilitation of patients with AT. Further research is necessary to determine the efficacy of adding joint mobilization to standard care for AT. Case series. Therapy, Level 4.

Objective was to evaluate the use of antibiotics prescribed in hospital outpatient and emergency clinics in King Hussein Medical Centre (KHMC) using WHO prescribing indicators in an attempt to rationalize the use of antibiotics in the Royal Medical Services. We retrospectively surveyed a sample of 187,822 antibiotic prescriptions obtained from 5 outpatient pharmacies in KHMC written over the period of 3 consecutive months May 2007 to July 2007. The percentage of encounters of an antibiotic prescribed was calculated using the methodology recommended by the WHO. An additional indicator, the percentage share of different antibiotics was also included to identify the frequency prescribed from those antibiotics. The average percentage of prescriptions involving antibiotics was 35.6% out of 187,822 prescriptions surveyed. From these, 65,500 antibiotic prescriptions were observed. Penicillins most frequently amoxcillins and Quinolones most frequently ciprofloxacinllin and norfloxacillin were the most commonly prescribed antibiotics with an average percentage of 31.8% and 27.5%. The average prescribing rate for the other antibiotic categories was as follows: macrolides 5.2%, cephalosporins 16% and amoxcillins/clavulanate 5.4%. The high percentage of prescriptions involving antibiotics observed in KHMC pharmacies requires rational use of antibiotics and judicious prescribing by Military prescribers. An insight into factors influencing antibiotic prescribing patterns and adherence to antibiotic prescribing guidelines by the Military prescribers is warranted. (author)

The purpose of our study was to explore the prevalence, and the role of mood, exercise frequency, age, and gender differences of exercise dependence. Regular exercisers (N = 409) completed a socio-demographic questionnaire, the Exercise Dependence Scale, and the Profile of Mood States. For data analyses, the participants were stratified for sex and age (age ranges = young adults: 18-24 years, adults: 25-44 years, and middle-aged adults: 45-64 years). We found that: (a) 4.4% of the participants were classified as at-risk for exercise dependence; (b) the men and the two younger groups (i.e., young adults and adults) had higher exercise dependence scores; and (c) age, gender, exercise frequency, and mood state were related to exercise dependence. Our results support previous research on the prevalence of exercise dependence and reveal that adulthood may be the critical age for developing exercise dependence. These findings have practical implication for identifying individuals at-risk for exercise dependence symptoms, and may aid in targeting and guiding the implementation of prevention program for adults.

Two distinct types of specific respiratory muscle training (RMT), i.e. respiratory muscle strength (resistive/threshold) and endurance (hyperpnoea) training, have been established to improve the endurance performance of healthy individuals. We performed a systematic review and meta-analysis in order to determine the factors that affect the change in endurance performance after RMT in healthy subjects. A computerized search was performed without language restriction in MEDLINE, EMBASE and CINAHL and references of original studies and reviews were searched for further relevant studies. RMT studies with healthy individuals assessing changes in endurance exercise performance by maximal tests (constant load, time trial, intermittent incremental, conventional [non-intermittent] incremental) were screened and abstracted by two independent investigators. A multiple linear regression model was used to identify effects of subjects' fitness, type of RMT (inspiratory or combined inspiratory/expiratory muscle strength training, respiratory muscle endurance training), type of exercise test, test duration and type of sport (rowing, running, swimming, cycling) on changes in performance after RMT. In addition, a meta-analysis was performed to determine the effect of RMT on endurance performance in those studies providing the necessary data. The multiple linear regression analysis including 46 original studies revealed that less fit subjects benefit more from RMT than highly trained athletes (6.0% per 10 mL · kg⁻¹ · min⁻¹ decrease in maximal oxygen uptake, 95% confidence interval [CI] 1.8, 10.2%; p = 0.005) and that improvements do not differ significantly between inspiratory muscle strength and respiratory muscle endurance training (p = 0.208), while combined inspiratory and expiratory muscle strength training seems to be superior in improving performance, although based on only 6 studies (+12.8% compared with inspiratory muscle strength training, 95% CI 3

Most previous studies on the effects of therapeutic exercise on osteoarthritis (OA) of the hip joint included participants with knee OA or postoperative participants. Moreover, although some systematic reviews recommend therapeutic exercise for hip OA, a consensus on the effective interventional frequency has not been reached. This study aimed to investigate the effects of therapeutic exercise performed at different frequencies on physical function and health-related quality of life in participants with hip OA. Individuals diagnosed with hip OA (36 women, age 42-79 years; 19 in 2009 and 17 in 2010) were recruited from the cooperating medical institutions. They were divided into two groups depending on the frequency of therapeutic exercise: fortnightly in 2009 (fortnightly group) and weekly in 2010 (weekly group). Participants in each group performed the same land-based and aquatic exercises on the same day for a total of ten sessions. Muscle strength of the lower extremity, "timed up and go" (TUG), time of one-leg standing with open eyes (TOLS), Harris Hip Score, and scores of the Medical Outcomes Survey Short Form-36 questionnaire, were measured before and after interventions. The fortnightly group had no significant changes in lower-extremity muscle strength following intervention, but the strength of all muscles in the weekly group improved significantly after intervention. Further, in both groups, TUG and TOLS of the worse side of the hip joint significantly improved after interventions. Weekly exercise improves muscle strength of the lower extremity and may therefore be an effective interventional technique for managing hip OA. In addition, in persons with hip OA, therapeutic exercise consisting of both land- and water-based exercises markedly improved physical function.

We used spatial optimization to allocate and prioritize prescribed fire treatments in the fire-prone Bages County, central Catalonia (northeastern Spain). The goal of this study was to identify suitable strategic locations on forest lands for fuel treatments in order to: 1) disrupt major fire movements, 2) reduce ember emissions, and 3) reduce the likelihood of large fires burning into residential communities. We first modeled fire spread, hazard and exposure metrics under historical extreme fire weather conditions, including node influence grid for surface fire pathways, crown fraction burned and fire transmission to residential structures. Then, we performed an optimization analysis on individual planning areas to identify production possibility frontiers for addressing fire exposure and explore alternative prescribed fire treatment configurations. The results revealed strong trade-offs among different fire exposure metrics, showed treatment mosaics that optimize the allocation of prescribed fire, and identified specific opportunities to achieve multiple objectives. Our methods can contribute to improving the efficiency of prescribed fire treatment investments and wildfire management programs aimed at creating fire resilient ecosystems, facilitating safe and efficient fire suppression, and safeguarding rural communities from catastrophic wildfires. The analysis framework can be used to optimally allocate prescribed fire in other fire-prone areas within the Mediterranean region and elsewhere. Copyright © 2017 Elsevier B.V. All rights reserved.

Full Text Available Jacqueline Fong,1,2 Thomas Buckley,2 Andrew Cashin3 1St George Hospital, Kogarah, 2Sydney Nursing School, University of Sydney, Camperdown, NSW, Australia; 3School of Health and Human Sciences, Southern Cross University, Lismore, NSW, Australia Background: Internationally, the delivery of care provided by nurses and midwives has undergone a significant change due to a variety of interrelated factors, including economic circumstances, a diminishing number of medical providers, the unavailability of adequate health care services in underserved and rural areas, and growing specialization among the professions. One solution to the challenges of care delivery has been the introduction of nurse practitioners (NPs and the authorization of NPs to prescribe medicines. Aim: The aim of this paper was to review the current international literature related to NP prescribing and compare the findings to the Australian context. The review focuses on literature from the United States, Canada, Europe, Australia, and New Zealand. Methods: Databases were searched from January 2000 to January 2015. The following keywords: “nurse practitioner”, “advanced nurse”, “advanced practice nurse”, “prescri*”, “Australia”, “United States America”, “UK”, “New Zealand”, “Canada”, “Europe”, “drug prescri*”, “prescri* authority”, and “prescri* legislation” were used. Findings: NPs tend to prescribe in differing contexts of practice to provide care in underserved populations and require good systems literacy to practice across complex systems. The key themes identified internationally related to NP prescribing relate to barriers to prescribing, confidence in prescribing, and the unique role of NPs in prescribing medicines, eg, the high prevalence of prescribing pain medicines in several countries, including Australia. Conclusion: Across all countries reviewed, there appears a need for further research into the organizational and

Safe prescribing: a titanic challenge.

The challenge to achieve safe prescribing merits the adjective 'titanic'. The organisational and human errors leading to poor prescribing (e.g. underprescribing, overprescribing, misprescribing or medication errors) have parallels in the organisational and human errors that led to the loss of the Titanic 100 years ago this year. Prescribing can be adversely affected by communication failures, critical conditions, complacency, corner cutting, callowness and a lack of courage of conviction, all of which were also factors leading to the Titanic tragedy. These issues need to be addressed by a commitment to excellence, the final component of the 'Seven C's'. Optimal prescribing is dependent upon close communication and collaborative working between highly trained health professionals, whose role is to ensure maximum clinical effectiveness, whilst also protecting their patients from avoidable harm. Since humans are prone to error, and the environments in which they work are imperfect, it is not surprising that medication errors are common, occurring more often during the prescribing stage than during dispensing or administration. A commitment to excellence in prescribing includes a continued focus on lifelong learning (including interprofessional learning) in pharmacology and therapeutics. This should be accompanied by improvements in the clinical working environment of prescribers, and the encouragement of a strong safety culture (including reporting of adverse incidents as well as suspected adverse drug reactions whenever appropriate). Finally, members of the clinical team must be prepared to challenge each other, when necessary, to ensure that prescribing combines the highest likelihood of benefit with the lowest potential for harm. © 2012 The Author.

Although prescribing of medication in hospitals is rarely an error-free process, prescribers receive little feedback on their mistakes and ways to change future practices. Audit and feedback interventions may be an effective approach to modifying the clinical practice of health professionals, but these may pose logistical challenges when used in hospitals. Moreover, such interventions are often labor intensive. Consequently, there is a need to develop effective and innovative interventions to overcome these challenges and to improve the delivery of feedback on prescribing. Implementation intentions, which have been shown to be effective in changing behavior, link critical situations with an appropriate response; however, these have rarely been used in the context of improving prescribing practices. Semistructured qualitative interviews were conducted to evaluate the acceptability and feasibility of providing feedback on prescribing errors via MyPrescribe, a mobile-compatible website informed by implementation intentions. Data relating to 200 prescribing errors made by 52 junior doctors were collected by 11 hospital pharmacists. These errors were populated into MyPrescribe, where prescribers were able to construct their own personalized action plans. Qualitative interviews with a subsample of 15 junior doctors were used to explore issues regarding feasibility and acceptability of MyPrescribe and their experiences of using implementation intentions to construct prescribing action plans. Framework analysis was used to identify prominent themes, with findings mapped to the behavioral components of the COM-B model (capability, opportunity, motivation, and behavior) to inform the development of future interventions. MyPrescribe was perceived to be effective in providing opportunities for critical reflection on prescribing errors and to complement existing training (such as junior doctors' e-portfolio). The participants were able to provide examples of how they would use

Aging is characterized by increasing muscle loss, physical inactivity and frailty. Physical inactivity is known to be associated with increased incidence of obesity and many life-threatening chronic conditions. We know that exercise, through many factors including antiinflammatory effects and enhanced fitness, can help prevent and treat many chronic diseases as well as help maintain independent living. We set out to demonstrate the utility of regular exercise in this potentially vulnerable age group in both the treatment and prevention of chronic diseases. The benefits, risks and recommendations for physical activity are discussed with an emphasis on practical advice for safe exercise in the context of established international guidelines. These guidelines typically state that 150 min per week of moderate aerobic intensity exercise should be achieved with some additional whole-body strength training and balance work. Individual risk assessment should be undertaken in a way to enable safe exercise participation to achieve maximum benefit with minimum risk. The risk assessment, subsequent advice and prescription for exercise should be personalized to reflect individual fitness and functional levels as well as patient safety. Newer and potentially exciting benefits of exercise are discussed in the areas of neuroscience and inflammation where data are suggesting positive effects of exercise in maintaining memory and cognition as well as having beneficial antiinflammatory effects.

Cancer and Exercise: Warburg Hypothesis, Tumour Metabolism and High-Intensity Anaerobic Exercise.

Hofmann, Peter

2018-01-31

There is ample evidence that regular moderate to vigorous aerobic physical activity is related to a reduced risk for various forms of cancer to suggest a causal relationship. Exercise is associated with positive changes in fitness, body composition, and physical functioning as well as in patient-reported outcomes such as fatigue, sleep quality, or health-related quality of life. Emerging evidence indicates that exercise may also be directly linked to the control of tumour biology through direct effects on tumour-intrinsic factors. Beside a multitude of effects of exercise on the human body, one underscored effect of exercise training is to target the specific metabolism of tumour cells, namely the Warburg-type highly glycolytic metabolism. Tumour metabolism as well as the tumour⁻host interaction may be selectively influenced by single bouts as well as regularly applied exercise, dependent on exercise intensity, duration, frequency and mode. High-intensity anaerobic exercise was shown to inhibit glycolysis and some studies in animals showed that effects on tumour growth might be stronger compared with moderate-intensity aerobic exercise. High-intensity exercise was shown to be safe in patients; however, it has to be applied carefully with an individualized prescription of exercise.

This study aimed to determine the suitability of the load-velocity relationship to prescribe the relative load (%1RM) in women, as well as to compare the load-velocity profile between sexes and participants with different strength levels. The load-velocity relationship of 14 men (1RM: 1.17 ± 0.19) and 14 women (1RM: 0.66 ± 0.13) were evaluated in the bench press exercise. The main findings revealed that: (I) the load-velocity relationship was always strong and linear (R 2 range: 0.987-0.993), (II) a steeper load-velocity profile was observed in men compared to women (Effect size [ES]: 1.09), with men showing higher velocities for light loads (ES: - 0.81 and - 0.40 for the y-intercept and 30%1RM, respectively), but women reporting higher velocities for the heavy loads (ES: 1.14 and 1.50 at 90%1RM and 100%1RM, respectively); and (III) while the slope of the load-velocity profile was moderately steeper for weak men compared to their strong counterpart (ES: 1.02), small differences were observed between strong and weak women (ES: - 0.39). While these results support the use of the individual load-velocity relationship to prescribe the %1RM in the bench press exercise for women, they also highlight the large disparities in their load-velocity profile compared to men.

Resistance Exercise to Prevent and Manage Sarcopenia and Dynapenia.

Science.gov (United States)

Law, Timothy D; Clark, Leatha A; Clark, Brian C

For well over twenty centuries the muscle wasting (sarcopenia) and weakness (dynapenia) that occurs with old age has been a predominant concern of mankind. Exercise has long been suggested as a treatment to combat sarcopenia and dynapenia, as it exerts effects on both the nervous and muscular systems that are critical to positive physiological and functional adaptations (e.g., enhanced muscle strength). For more than two decades scientists have recognized the profound role that progressive resistance exercise training can have on increasing muscle strength, muscle size and functional capacity in older adults. In this review article we discuss how resistance exercise training can be used in the management and prevention of sarcopenia and dynapenia. We first provide an overview of the evidence for this notion and highlight certain critical factors- namely exercise intensity, volume and progression- that are key to optimizing the resistance exercise prescription. We then highlight how many, if not most, of the commonly prescribed exercise programs for seniors are not the 'best practices', and subsequently present easy-to-read guidelines for a well-rounded resistance exercise training program designed for the management and prevention of sarcopenia and dynapenia, including example training programs for the beginner through the advanced senior resistance exerciser. These guidelines have been written for the academician as well as the student and health care provider across a variety of disciplines, including those in the long term care industry, such as wellness instructors or activity directors.

Pain and limited range of motion (ROM) are the crucial subsequent results of joint hemorrhages in individuals with bleeding disorders and hemophilia. Exercise interventions are particularly recommended in treatment of such patients. The purpose of this study was to detect the influences of conventional exercise therapy and hydrotherapy on the knee joint complications in patients with hemophilia. A total of 40 patients engaging hemophilia A were randomized into one of three groups: Therapeutic exercise (N = 13), hydrotherapy (N = 14) or control (N = 13). While the first two groups followed their specific programs for 4 weeks, routine life-style was maintained by subjects in the control group in this period. To evaluate the pain level and knee ROM the visual analog scale and standard goniometer were utilized, respectively. The outcome was measured at baseline and after completing the prescribed protocols. Data analysis was performed using one-way analysis of variance and Scheffe statistical tests (P hydrotherapy in comparison to exercise therapy, the difference in ROM improvement was not statistically significant (P > 0.05). Using hydrotherapy in addition to usual rehabilitation training can result in beneficial effect in terms of pain and knee joint ROM. However, it appears that hydrotherapy is more effective in reducing pain.

In exercising muscles force production and muscular endurance are impaired by a decrease in intramuscular pH. The effects of aerobic training (AT) on preventing acidosis and prolonging exercise time in muscles not specifically targeted by the training are unknown. Purpose: To compare interstitial pH, measured non-invasively with near infrared spectroscopy (NIRS), in the flexor digitorum profundus (FDP) during rhythmic handgrip exercise in sedentary subjects and those who participate in AT activities that target the lower body. Methods: Maximal isometric force (MIF) was measured on three separate days in AT (n=5) and sedentary (n=8) subjects using a handgrip dynamometer (HGD). Isometric muscular endurance (IME) was measured during five trials, each separated by at least 48 hrs. For each IME trial subjects rhythmically squeezed (4 sec at 40% of MVC) and relaxed (2 sec) to fatigue or failure to reach the target force in three consecutive contractions or four non-consecutive contractions. Interstitial pH was derived from spectra collected using a NIRS sensor adhered to the skin over the FDP. The first four IME trials served to familiarize subjects with the protocol; the fifth trial was used for analysis. NIRS-derived pH was averaged in 30 sec increments. Between group differences in MIF and exercise time were tested using paired t-tests. A repeated measures ANOVA was used to analyze effects of AT and exercise time on pH. Results: MIF was not different between groups (mean SD; aerobic=415.6 95.4 N vs. sedentary =505.1 107.4 N). Time to fatigue was greater in the AT than in the sedentary group (mean SD: 611 173 sec vs. 377 162 sec, p<0.05). pH was not different between groups at any time point. Average pH decreased (p<0.05) in both groups from rest (pH=7.4) through 90 sec of exercise (pH=6.9), but did not decrease further throughout the remainder of exercise. Conclusion: Although between group differences in pH were not detected, differences during the onset of exercise

Playing it safe: exercise and cardiovascular health.

Regular physical activity controls acquired cardiovascular risk factors such as obesity, diabetes mellitus, hypertension and hyperlipidaemia. Exercise is generally associated with a 50% reduction in adverse events from coronary artery disease (CAD). The benefits of exercise extend well beyond the cardiovascular system. Recent evidence suggests that exercise prevents cell senescence, and active individuals are at lower risk of developing certain malignancies including cancer of the prostate and the colon, osteoporosis, depression and dementia. Individuals who exercise regularly extend their life expectancy by three to seven years. Healthy individuals should engage in 150 minutes of moderate-intensity, aerobic exercise per week. Recent studies have demonstrated that even lower volumes of exercise below these recommendations confer health benefits, which is highly relevant to individuals with established cardiac disease including heart failure. Sudden cardiac death in athletes under 35 is rare with.estimates ranging from 1 in 50,000 to 1 in 200,000. Hereditary and congenital abnormalities of the heart are the most common cause of nontraumatic death during sport in young athletes. In middle-aged recreational athletes more than 90% of sudden cardiac deaths occur in males and more than 90% are caused by atherosclerotic CAD. The AHA and the ESC advocate pre-participation screening of young athletes. The ECG has the ability to detect congenital accessory pathways and ion channelopathies, and is frequently abnormal in individuals with cardiomyopathy. Screening with a 12-lead ECG in older athletes is of limited value given the overwhelming contribution of atherosclerotic CAD to sudden cardiac death.

The pain medication OxyContin (hereafter referred to as oxycodone extended release) has been the subject of sustained, and largely negative, media attention in recent years. We sought to determine whether media coverage of oxycodone extended release in North American newspapers has led to changes in prescribing of the drug in Nova Scotia, Canada. An interrupted time-series design examined the effect of media attention on physicians' monthly prescribing of opioids. The outcome measures were, for each physician, the monthly proportions of all opioids prescribed and the proportion of strong opioids prescribed that were for oxycodone extended release. The exposure of interest was media attention defined as the number of articles published each month in 27 North American newspapers. Variations in media effects by provider characteristics (specialty, prescribing volume, and region) were assessed. Within-provider changes in the prescribing of oxycodone extended release in Nova Scotia were observed, and they followed changes in media coverage. Oxycodone extended release prescribing rose steadily prior to receiving media attention. Following peak media attention in the United States, the prescribing of oxycodone extended release slowed. Likewise, following peak coverage in Canadian newspapers, the prescribing of oxycodone extended release declined. These patterns were observed across prescriber specialties and by prescriber volume, though the magnitude of change in prescribing varied. This study demonstrates that print media reporting of oxycodone extended release in North American newspapers, and its continued portrayal as a social problem, coincided with reductions in the prescribing of oxycodone extended release by physicians in Nova Scotia.

The last decade has seen a drive towards non-medical prescribing in the United Kingdom (UK). However, there is a dearth of any published literature on applying the principles of service redesign to support pharmacist prescribing in any sphere of practice. To develop consensus guidance to facilitate service redesign around pharmacist prescribing. UK hospital practice. The Delphi technique was used to measure consensus of a panel of expert opinion holders in Scotland. Individuals with key strategic and operational roles in implementing initiatives of pharmacy practice and medicines management were recruited as experts. An electronic questionnaire consisting of 30 statements related to pharmacist prescribing service redesign was developed. These were presented as five-point Likert scales with illustrative quotes. Consensus, defined as 70 % of panel members agreeing (ranked strongly agree/agree) with each statement. Responses were obtained from 35/40 (87.5 %) experts in round one and 29 (72.5 %) in round two. Consensus in round one was achieved for 27/30 of statements relating to aspects of generic 'service development' (e.g. succession planning, multidisciplinary working, quality evaluation, practice development and outcome measures) and 'pharmacist prescribing role development' (e.g. education and future orientation of service). Issues of disagreement were around targeting of pharmacist prescribing to clinical specialities and financial remuneration for prescribing in the hospital setting. Consensus guidance has been developed to facilitate service redesign around hospital pharmacist prescribing.

Full Text Available Background & Objectives: Older individuals often suffer from multiple systemic diseases and are particularly more vulnerable to potentially inappropriate medicine prescribing. Inappropriate medication can cause serious medical problem for the elderly. The study was conducted with objectives to determine the prevalence of potentially inappropriate medicine (PIM prescribing in older Nepalese patients in a medicine outpatient department.Materials & Methods: A prospective observational analysis of drugs prescribed in medicine out-patient department (OPD of a tertiary hospital of central Nepal was conducted during November 2012 to October 2013 among 869 older adults aged 65 years and above. The use of potentially inappropriate medications (PIM in elderly patients was analysed using Beer’s Criteria updated to 2013. Results: In the 869 patients included, the average number of drugs prescribed per prescription was 5.56. The most commonly used drugs were atenolol (24.3%, amlodipine (23.16%, paracetamol (17.6%, salbutamol (15.72% and vitamin B complex (13.26%. The total number of medications prescribed was 4833. At least one instance of PIM was experienced by approximately 26.3% of patients when evaluated using the Beers criteria. Conclusion: Potentially inappropriate medications are highly prevalent among older patients attending medical OPD and are associated with number of medications prescribed. Further research is warranted to study the impact of PIMs towards health related outcomes in these elderly.

Full Text Available Sport is an essential part of childhood, with precious and acknowledged positive health effects but the impact of exercise-induced bronchoconstriction (EIB significantly reduces participation in physical activity. It is important to recognize EIB, differentiating EIB with or without asthma if the transient narrowing of the airways after exercise is associated with asthmatic symptoms or not, in the way to select the most appropriate treatment among the many treatment options available today. Therapy is prescribed based on symptoms severity but diagnosis of EIB is established by changes in lung function provoked by exercise evaluating by direct and indirect tests. Sometimes, in younger children it is difficult to obtain the registration of difference between the preexercise forced expiratory volume in the first second (FEV1 value and the lowest FEV1 value recorded within 30 min after exercise, defined as the gold standard, but interrupter resistance, in association with spirometry, has been showed to be a valid alternative in preschool age. Atopy is the main risk factor, as demonstrated by epidemiologic data showing that among the estimated pediatric population with EIB up to 40% of them have allergic rhinitis and 30% of these patients may develop adult asthma, according with atopic march. Adopting the right treatment and prevention, selecting sports with no marked hyperventilation and excessive cooling of the airways, children with EIB can be able to take part in physical activity like all others.

To assess supplement intake in people who exercise regularly in gyms in the city of Belo Horizonte, Brazil, and discuss the influencing factors on its ingestion. A total of 1102 enrolled subjects who exercised in 50 gyms throughout the city were part of this cross-sectional study. Men and women were recruited and all subjects were at least 18 y old. Participants were asked to complete written questionnaires about their use of supplements. Data were collected over a period of 4 mo. Descriptive statistics and chi-square tests were performed. The intake of nutritional supplements was reported by 36.8% of participants. The highest intake was in men (44.6%). Five products were consumed almost daily: those rich in proteins and amino acids (58%), isotonic drinks (32%), those rich in carbohydrates (23%), natural/phytotherapeutic (20%), and multivitamin/mineral supplements (19%). Most people (55%) reported using nutritional supplements without any specialized professional guidance and based primarily on self-prescription. Individuals younger than 30 y, mainly men (odds ratio 3.28, 95% confidence interval 2.06-5.20, P gyms is high and is usually self-prescribed. We emphasize that the use of dietary supplements must be always done under the supervision of a specialist (physician or nutritionist). Copyright 2010 Elsevier Inc. All rights reserved.

It has been suggested that the employment of pharmacists in general practice might moderate the growth in prescribing costs. However, empirical evidence for this proposition has been lacking. We report the results of a controlled trial of pharmacist intervention in United Kingdom general practice. To determine whether intervention practices made savings relative to controls. An evaluation of an initiative set up by Doncaster Health Authority. Eight practices agreed to take part and received intensive input from five pharmacists for one year (September 1996 to August 1997) at a cost of 163,000 Pounds. Changes in prescribing patterns were investigated by comparing these practices with eight individually matched controls for both the year of the intervention and the previous year. Prescribing data (PACTLINE) were used to assess these changes. The measures used to take account of differences in the populations of the practices included the ASTRO-PU for overall prescribing and the STAR-PU for prescribing in specific therapeutic areas. Differences between intervention and control practices were subjected to Wilcoxon matched-pairs, signed-ranks tests. The median (minimum to maximum) rise in prescribing costs per ASTRO-PU was 0.85 Pound (-1.95 Pounds to 2.05 Pounds) in the intervention practices compared with 2.55 Pounds (1.74 Pounds to 4.65 Pounds) in controls (P = 0.025). Had the cost growth of the intervention group been as high as that of the controls, their total prescribing expenditure would have been around 347,000 Pounds higher. This study suggests that the use of pharmacists did control prescribing expenditure sufficiently to offset their employment costs.

To evaluate the feasibility and preliminary effects of an individualized exercise programme with and without behavioural change enhancement strategies for frail older people with fatigue. A three-arm, single-blinded, quasi-experimental pilot study. Community health centres. A total of 79 frail older people with fatigue, mean age 79.32 years (±7.72). The combined group received a 16-week combined intervention consisting of exercise training and a behavioural change enhancement programme. The exercise group received exercise training and health talks, whereas the control group received only health talks. Feasibility was assessed through the participants' recruitment, retention, attendance and adherence, feedback, and reports of adverse events. The preliminary effects were assessed by the participants' level of fatigue, physical endurance, self-efficacy, and self-perceived compliance with exercise. Feasibility was achievable with high recruitment (87.2%) and low overall attrition (7.1%) rates. A similar reduction in fatigue was identified in all groups, but a trend of greater improvement in physical endurance was observed in the combined group than in the other two groups. The combined group also had a significantly better attendance rate [F(2,76) = 5.64, p behavioural change, when the participants are establishing the habit of exercising daily.

Knee and hip osteoarthritis (OA) is a leading cause of disability worldwide. Therapeutic exercise is a recommended core treatment for people with knee and hip OA, however, the observed effect sizes for reducing pain and improving physical function are small to moderate. This may be due to insufficient targeting of exercise to subgroups of people who are most likely to respond and/or suboptimal content of exercise programmes. This study aims to identify: (1) subgroups of people with knee and hip OA that do/do not respond to therapeutic exercise and to different types of exercise and (2) mediators of the effect of therapeutic exercise for reducing pain and improving physical function. This will enable optimal targeting and refining the content of future exercise interventions. Systematic review and individual participant data meta-analyses. A previous comprehensive systematic review will be updated to identify randomised controlled trials that compare the effects of therapeutic exercise for people with knee and hip OA on pain and physical function to a non-exercise control. Lead authors of eligible trials will be invited to share individual participant data. Trial-level and participant-level characteristics (for baseline variables and outcomes) of included studies will be summarised. Meta-analyses will use a two-stage approach, where effect estimates are obtained for each trial and then synthesised using a random effects model (to account for heterogeneity). All analyses will be on an intention-to-treat principle and all summary meta-analysis estimates will be reported as standardised mean differences with 95% CI. Research ethical or governance approval is exempt as no new data are being collected and no identifiable participant information will be shared. Findings will be disseminated via national and international conferences, publication in peer-reviewed journals and summaries posted on websites accessed by the public and clinicians.

Cardiac parasympathetic reactivation following exercise: implications for training prescription.

Science.gov (United States)

Stanley, Jamie; Peake, Jonathan M; Buchheit, Martin

2013-12-01

The objective of exercise training is to initiate desirable physiological adaptations that ultimately enhance physical work capacity. Optimal training prescription requires an individualized approach, with an appropriate balance of training stimulus and recovery and optimal periodization. Recovery from exercise involves integrated physiological responses. The cardiovascular system plays a fundamental role in facilitating many of these responses, including thermoregulation and delivery/removal of nutrients and waste products. As a marker of cardiovascular recovery, cardiac parasympathetic reactivation following a training session is highly individualized. It appears to parallel the acute/intermediate recovery of the thermoregulatory and vascular systems, as described by the supercompensation theory. The physiological mechanisms underlying cardiac parasympathetic reactivation are not completely understood. However, changes in cardiac autonomic activity may provide a proxy measure of the changes in autonomic input into organs and (by default) the blood flow requirements to restore homeostasis. Metaboreflex stimulation (e.g. muscle and blood acidosis) is likely a key determinant of parasympathetic reactivation in the short term (0-90 min post-exercise), whereas baroreflex stimulation (e.g. exercise-induced changes in plasma volume) probably mediates parasympathetic reactivation in the intermediate term (1-48 h post-exercise). Cardiac parasympathetic reactivation does not appear to coincide with the recovery of all physiological systems (e.g. energy stores or the neuromuscular system). However, this may reflect the limited data currently available on parasympathetic reactivation following strength/resistance-based exercise of variable intensity. In this review, we quantitatively analyse post-exercise cardiac parasympathetic reactivation in athletes and healthy individuals following aerobic exercise, with respect to exercise intensity and duration, and fitness

Antioxidant capacity and physical exercise

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 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.

About one-third of peripheral arterial disease patients have intermittent claudication with deleterious effects on everyday activities, such as walking. Exercise training improves peripheral arterial disease symptoms and is recommended as first line therapy for peripheral arterial disease. This review examines the effects of exercise training beyond improvements in walking distance, namely on vascular function, parameters of inflammation, activated hemostasis and oxidative stress, and quality of life. Exercise training not only increases walking distance and physiologic parameters in patients with peripheral arterial disease, but also improves the cardiovascular risk profile by helping patients achieve better control of hypertension, hyperglycemia, obesity and dyslipidemia, thus further reducing cardiovascular risk and the prevalence of coexistent atherosclerotic diseases. American guidelines suggest supervised exercise training, performed for a minimum of 30-45 min, at least three times per week, for at least 12 weeks. Walking is the most studied exercise modality and its efficacy in improving cardiovascular parameters in patients with peripheral arterial disease has been extensively proven. As studies have shown that supervised exercise training improves walking performance, cardiovascular parameters and quality of life in patients with peripheral arterial disease, it should be encouraged and more often prescribed.

The article presents University of Idaho - Physical Rehabilitation Movement Data (UI-PRMD) - a publically available data set of movements related to common exercises performed by patients in physical rehabilitation programs. For the data collection, 10 healthy subjects performed 10 repetitions of different physical therapy movements, with a Vicon optical tracker and a Microsoft Kinect sensor used for the motion capturing. The data are in a format that includes positions and angles of full-body joints. The objective of the data set is to provide a basis for mathematical modeling of therapy movements, as well as for establishing performance metrics for evaluation of patient consistency in executing the prescribed rehabilitation exercises.

[Purpose] This study prescribed pain-free range exercises for a female amateur skier who complained of limitations in her shoulder range of motion, and pain caused by protective spasms; the tester evaluated the effects of such exercise on pain. [Subject and Methods] A 23-year-old female who complained of pain of 3 weeks in duration in the right glenohumoral and scapulothoracic joints was enrolled. [Results] After pain-free range exercises, the visual analog pain score was 2 and the shoulder flexion and abduction angles improved compared to the initial values. [Conclusion] Thus, this study suggests muscle-strengthening exercises within the pain-free range, rather than simple pain treatments, as therapy for acute muscle injuries in skiers.

Full Text Available This study examines if electromyographic (EMG amplitude differences exist between patients with shoulder instability and healthy controls performing scaption, prone horizontal abduction, prone external rotation, and push-up plus shoulder rehabilitation exercises. Thirty nine subjects were categorized by a single orthopedic surgeon as having multidirectional instability (n=10, anterior instability (n=9, generalized laxity (n=10, or a healthy shoulder (n=10. Indwelling and surface electrodes were utilized to measure EMG activity (reported as a % of maximum voluntary isometric contraction (MVIC in various shoulder muscles during 4 common shoulder exercises. The exercises studied effectively activated the primary musculature targeted in each exercise equally among all groups. The serratus anterior generated high activity (50–80% MVIC during a push-up plus, while the infraspinatus and teres major generated moderate-to-high activity (30–80% MVIC during both the prone horizontal and prone external rotation exercises. Scaption exercise generated moderate activity (20–50% MVIC in both rotator cuff and scapular musculature. Clinicians should feel confident in prescribing these shoulder-strengthening exercises in patients with shoulder instability as the activation levels are comparable to previous findings regarding EMG amplitudes and should improve the dynamic stabilization capability of both rotator cuff and scapular muscles using exercises designed to address glenohumeral joint instability.

Regular aerobic exercise at moderate intensities and an increased physical fitness are associated with a reduced risk of fatal and nonfatal coronary events in middle-aged individuals. In contrast, moderate and vigorous physical exertion is associated with an increased risk for cardiac events, including sudden cardiac death in individuals harbouring cardiovascular disease. The risk-benefit ratio may differ in relation to the individual’s age, fitness level, and presence of cardiovascular disease; sedentary individuals with underlying coronary artery disease are at greatest risk. The intention of the present position stand of the European Association of Cardiovascular Prevention and Rehabilitation is to encourage individuals to participate in regular physical activity and derive the benefits of physical exercise while minimizing the risk of cardiovascular adverse events. Therefore, the aim is to establish the most practical method of cardiovascular evaluation in middle-age/senior individuals, who are contemplating exercise or who are already engaged in nonprofessional competitive or recreational leisure sporting activity. These recommendations rely on existing scientific evidence, and in the absence of such, on expert consensus. The methodology of how middle-aged and older individuals should be evaluated appropriately before engaging in regular physical activity is both complex and controversial. On practical grounds the consensus panel recommend that such evaluation should vary according to the individual’s cardiac risk profile and the intended level of physical activity. Self assessment of the habitual physical activity level and of the risk factors, are recommended for screening of large populations. Individuals deemed to be at risk require further evaluation by a qualified physician. In senior/adult individuals with an increased risk for coronary events, maximal exercise testing (and possibly further evaluations) is advocated. Hopefully, the recommendations

Suboptimal prescribing persists as a driver of poor quality care of older veterans and is associated with risk of hospitalization and emergency department visits. We adapted a successful medication management model, Integrated Management and Polypharmacy Review of Vulnerable Elders (IMPROVE), from an urban geriatric specialty clinic to rural community-based clinics that deliver primary care. The goals were to promote prescribing quality and safety for older adults, including reduced prescribing of potentially inappropriate medications (PIMs). We augmented the original model, which involved a pharmacist-led, one-on-one medication review with high-risk older veterans, to provide rural primary care providers (PCPs) and pharmacists with educational outreach through academic detailing and tools to support safe geriatric prescribing practices, as well as individual audit and feedback on prescribing practice and confidential peer benchmarking. Twenty PCPs and 4 pharmacists at 4 rural Georgia community-based outpatient clinics participated. More than 7,000 older veterans were seen in more than 20,000 PCP encounters during the 14-month intervention period. Implementation of the IMPROVE intervention reduced PIM prescribing incidence from 9.6 new medications per 100 encounters during baseline to 8.7 after the intervention (P = .009). IMPROVE reduced PIM prevalence (proportion of encounters involving veterans who were taking at least 1 PIM) from 22.6% to 16.7% (P < .001). These approaches were effective in reducing PIMs prescribed to older veterans in a rural setting and constitute a feasible model for disseminating geriatric best practices to the primary care setting. © 2018, Copyright the Authors Journal compilation © 2018, The American Geriatrics Society.

Evidence indicates that regular exercise improves the well-being of individuals with osteoarthritis (OA). However, these individuals seem to exercise less frequently than the general population and seem to have limited adherence to exercising. The purposes of this study were: (1) to increase knowledge and understanding of the experience of exercising among individuals with OA and (2) to determine what they perceive as facilitators and barriers to exercising. This study used a qualitative method, based on the Vancouver School of doing phenomenology, involving purposive sampling of 12 individuals and 16 interviews. The participants, 9 women and 3 men, were 50 to 82 years of age. Extended information on exercise behavior among people with OA is presented in a model in which internal and external facilitators and barriers to exercising are delineated. Based on this model, a checklist is proposed for physical therapists' assessment of these factors. Internal factors include individual attributes and personal experience of exercising, whereas external factors include the social and physical environment. The participants expressed how each of these internal and external factors could act both as a facilitator and a barrier to exercise participation and the pattern of exercising; for example, the presence of pain was an important aspect concerning internal barriers to exercising, whereas the hope of less pain was one of the main facilitators. Increased knowledge and understanding of the factors influencing exercise behavior in people with OA can help physical therapists and other health care professionals support them in initiating and maintaining a healthy exercise routine and, consequently, achieving a better quality of life.

Irisin is a recently identified exercise-induced myokine. However, the circulating levels of irisin in response to different types of exercise in subjects with metabolic syndrome are unknown. This study aimed to study the levels of irisin in healthy males and subjects with metabolic syndrome at baseline and in response to exercise. Each individual completed high-intensity interval exercise (HIIE), continuous moderate-intensity exercise (CME), and resistance exercise (RE) sessions in a random, crossover design. Percentage change in circulating irisin levels was examined. Two different irisin assays were used to compare the results of the RE study. Circulating irisin increased immediately after HIIE, CME, and RE and declined 1 hour later. The increase was greater in response to resistance compared with either high-intensity intermittent exercise or CME. Change in irisin in response to exercise did not differ between individuals with and without metabolic syndrome. Exercise is able to increase circulating irisin levels in individuals with the metabolic syndrome as well as healthy individuals. Whether this increase may contribute to the beneficial effects of exercise on patients with the metabolic syndrome remains to be studied further.

Few detailed studies exist of the underlying causes of prescribing errors in the UK. To examine the causes of prescribing and monitoring errors in general practice and provide recommendations for how they may be overcome. Qualitative interview and focus group study with purposive sampling of English general practices. General practice staff from 15 general practices across three PCTs in England participated in a combination of semi-structured interviews (n = 34) and six focus groups (n = 46). Thematic analysis informed by Reason's Accident Causation Model was used. Seven categories of high-level error-producing conditions were identified: the prescriber, the patient, the team, the working environment, the task, the computer system, and the primary-secondary care interface. These were broken down to reveal various error-producing conditions: the prescriber's therapeutic training, drug knowledge and experience, knowledge of the patient, perception of risk, and their physical and emotional health; the patient's characteristics and the complexity of the individual clinical case; the importance of feeling comfortable within the practice team was highlighted, as well as the safety implications of GPs signing prescriptions generated by nurses when they had not seen the patient for themselves; the working environment with its extensive workload, time pressures, and interruptions; and computer-related issues associated with mis-selecting drugs from electronic pick-lists and overriding alerts were all highlighted as possible causes of prescribing errors and were often interconnected. Complex underlying causes of prescribing and monitoring errors in general practices were highlighted, several of which are amenable to intervention.

Dietary antioxidants and exercise.

Powers, Scott K; DeRuisseau, Keith C; Quindry, John; Hamilton, Karyn L

Muscular exercise promotes the production of radicals and other reactive oxygen species in the working muscle. Growing evidence indicates that reactive oxygen species are responsible for exercise-induced protein oxidation and contribute to muscle fatigue. To protect against exercise-induced oxidative injury, muscle cells contain complex endogenous cellular defence mechanisms (enzymatic and non-enzymatic antioxidants) to eliminate reactive oxygen species. Furthermore, exogenous dietary antioxidants interact with endogenous antioxidants to form a cooperative network of cellular antioxidants. Knowledge that exercise-induced oxidant formation can contribute to muscle fatigue has resulted in numerous investigations examining the effects of antioxidant supplementation on human exercise performance. To date, there is limited evidence that dietary supplementation with antioxidants will improve human performance. Furthermore, it is currently unclear whether regular vigorous exercise increases the need for dietary intake of antioxidants. Clearly, additional research that analyses the antioxidant requirements of individual athletes is needed.

We studied the blood pressure lowering effects of a bout of exercise and/or antihypertensive medicine with the goal of studying if exercise could substitute or enhance pharmacologic hypertension treatment. Twenty-three hypertensive metabolic syndrome patients chronically medicated with angiotensin II receptor 1 blockade antihypertensive medicine underwent 24-hr monitoring in four separated days in a randomized order; a) after taking their habitual dose of antihypertensive medicine (AHM trial), b) substituting their medicine by placebo medicine (PLAC trial), c) placebo medicine with a morning bout of intense aerobic exercise (PLAC+EXER trial) and d) combining the exercise and antihypertensive medicine (AHM+EXER trial). We found that in trials with AHM subjects had lower plasma aldosterone/renin activity ratio evidencing treatment compliance. Before exercise, the trials with AHM displayed lower systolic (130±16 vs 133±15 mmHg; P=0.018) and mean blood pressures (94±11 vs 96±10 mmHg; P=0.036) than trials with placebo medication. Acutely (i.e., 30 min after treatments) combining AHM+EXER lowered systolic blood pressure (SBP) below the effects of PLAC+EXER (-8.1±1.6 vs -4.9±1.5 mmHg; P=0.015). Twenty-four hour monitoring revealed no differences among trials in body motion. However, PLAC+EXER and AHM lowered SBP below PLAC during the first 10 hours, time at which PLAC+EXER effects faded out (i.e., at 19 PM). Adding exercise to medication (i.e., AHM+EXER) resulted in longer reductions in SBP than with exercise alone (PLAC+EXER). In summary, one bout of intense aerobic exercise in the morning cannot substitute the long-lasting effects of antihypertensive medicine in lowering blood pressure, but their combination is superior to exercise alone.

Stenner, Karen; Carey, Nicola; Courtenay, Molly

2010-03-01

This paper is a report of a study exploring the views of nurses and team members on the implementation of nurse prescribing in diabetes services. Nurse prescribing is adopted as a means of improving service efficiency, particularly where demand outstretches resources. Although factors that support nurse prescribing have been identified, it is not known how these function within specific contexts. This is important as its uptake and use varies according to mode of prescribing and area of practice. A case study was undertaken in nine practice settings across England where nurses prescribed medicines for patients with diabetes. Thematic analysis was conducted on qualitative data from 31 semi-structured interviews undertaken between 2007 and 2008. Participants were qualified nurse prescribers, administrative staff, physicians and non-nurse prescribers. Nurses prescribed more often following the expansion of nurse independent prescribing rights in 2006. Initial implementation problems had been resolved and few current problems were reported. As nurses' roles were well-established, no major alterations to service provision were required to implement nurse prescribing. Access to formal and informal resources for support and training were available. Participants were accepting and supportive of this initiative to improve the efficiency of diabetes services. The main factors that promoted implementation of nurse prescribing in this setting were the ability to prescribe independently, acceptance of the prescribing role, good working relationships between doctors and nurses, and sound organizational and interpersonal support. The history of established nursing roles in diabetes care, and increasing service demand, meant that these diabetes services were primed to assimilate nurse prescribing.

Wearable Sensor-Based Rehabilitation Exercise Assessment for Knee Osteoarthritis

Directory of Open Access Journals (Sweden)

Kun-Hui Chen

2015-02-01

Full Text Available Since the knee joint bears the full weight load of the human body and the highest pressure loads while providing flexible movement, it is the body part most vulnerable and susceptible to osteoarthritis. In exercise therapy, the early rehabilitation stages last for approximately six weeks, during which the patient works with the physical therapist several times each week. The patient is afterwards given instructions for continuing rehabilitation exercise by him/herself at home. This study develops a rehabilitation exercise assessment mechanism using three wearable sensors mounted on the chest, thigh and shank of the working leg in order to enable the patients with knee osteoarthritis to manage their own rehabilitation progress. In this work, time-domain, frequency-domain features and angle information of the motion sensor signals are used to classify the exercise type and identify whether their postures are proper or not. Three types of rehabilitation exercise commonly prescribed to knee osteoarthritis patients are: Short-Arc Exercise, Straight Leg Raise, and Quadriceps Strengthening Mini-squats. After ten subjects performed the three kinds of rehabilitation activities, three validation techniques including 10-fold cross-validation, within subject cross validation, and leave-one-subject cross validation are utilized to confirm the proposed mechanism. The overall recognition accuracy for exercise type classification is 97.29% and for exercise posture identification it is 88.26%. The experimental results demonstrate the feasibility of the proposed mechanism which can help patients perform rehabilitation movements and progress effectively. Moreover, the proposed mechanism is able to detect multiple errors at once, fulfilling the requirements for rehabilitation assessment.

2015-01-01

Doctor shopping is a primary method of prescription medication diversion. After opioids, benzodiazepines and stimulants are the next most common prescription medications used nonmedically. Studies have shown that patients who engage in doctor shopping find it fun, exciting, and easy to do. There is a lack of research on the prescriber's perspective on the phenomenon of doctor shopping. This study investigates the experiences of prescribers in psychiatry with patients who engage in doctor shopping. Fifteen prescribers including psychiatrists and psychiatric nurse practitioners working in outpatient psychiatry were interviewed to elicit detailed information about their experiences with patients who engage in doctor shopping. Themes found throughout the interview were that psychiatric prescribers' experience with patients who engage in doctor shopping includes (a) detecting red flags, (b) negative emotional responding, (c) addressing the patient and the problem, and (d) inconsistently implementing precautions. When red flags were detected when prescribing controlled drugs, prescribers in psychiatry experienced both their own negative emotional responses such as disappointment and resentment as well as the negative emotions of the patients such as anger and other extreme emotional responses. Psychiatric prescribers responded to patient's doctor shopping in a variety of ways such as changing their practice, discharging the patients or taking steps to not accept certain patients identified as being at risk for doctor shopping, as well as by talking to the patient and trying to offer them help. Despite experiencing doctor shopping, the prescribers inconsistently implemented precautionary measures such as checking prescription drug monitoring programs. © The Author(s) 2015.

A model of methods for influencing prescribing: Part I. A review of prescribing models, persuasion theories, and administrative and educational methods.

Science.gov (United States)

Raisch, D W

1990-04-01

The purpose of this literature review is to develop a model of methods to be used to influence prescribing. Four bodies of literature were identified as being important for developing the model: (1) Theoretical prescribing models furnish information concerning factors that affect prescribing and how prescribing decisions are made. (2) Theories of persuasion provide insight into important components of educational communications. (3) Research articles of programs to improve prescribing identify types of programs that have been found to be successful. (4) Theories of human inference describe how judgments are formulated and identify errors in judgment that can play a role in prescribing. This review is presented in two parts. This article reviews prescribing models, theories of persuasion, studies of administrative programs to control prescribing, and sub-optimally designed studies of educational efforts to influence drug prescribing.

Clinical decision support (CDS) in e-prescribing can improve safety by alerting potential errors, but introduces new sources of risk. Automation bias (AB) occurs when users over-rely on CDS, reducing vigilance in information seeking and processing. Evidence of AB has been found in other clinical tasks, but has not yet been tested with e-prescribing. This study tests for the presence of AB in e-prescribing and the impact of task complexity and interruptions on AB. One hundred and twenty students in the final two years of a medical degree prescribed medicines for nine clinical scenarios using a simulated e-prescribing system. Quality of CDS (correct, incorrect and no CDS) and task complexity (low, low + interruption and high) were varied between conditions. Omission errors (failure to detect prescribing errors) and commission errors (acceptance of false positive alerts) were measured. Compared to scenarios with no CDS, correct CDS reduced omission errors by 38.3% (p < .0001, n = 120), 46.6% (p < .0001, n = 70), and 39.2% (p < .0001, n = 120) for low, low + interrupt and high complexity scenarios respectively. Incorrect CDS increased omission errors by 33.3% (p < .0001, n = 120), 24.5% (p < .009, n = 82), and 26.7% (p < .0001, n = 120). Participants made commission errors, 65.8% (p < .0001, n = 120), 53.5% (p < .0001, n = 82), and 51.7% (p < .0001, n = 120). Task complexity and interruptions had no impact on AB. This study found evidence of AB omission and commission errors in e-prescribing. Verification of CDS alerts is key to avoiding AB errors. However, interventions focused on this have had limited success to date. Clinicians should remain vigilant to the risks of CDS failures and verify CDS.
