    Worksite wellness programs offer an ideal setting to target high-risk sedentary workers to improve health status. Lack of physical activity is associated with increased risk for coronary heart disease and mortality. Despite the risks, the number of sedentary workers is increasing. This study examined the perceived barriers and motivators for physical activity among employees at high-risk for coronary heart disease. A purposive sample of 24 high-risk workers participating in a wellness program in rural South Carolina were enrolled in the study. Qualitative data was obtained through semi-structured face-to-face interviews. Grounded theory was used to analyze qualitative data, and identify overarching themes. Physical limitations due to pain and weakness, lack of motivation, and lack of time emerged as the main barriers to physical activity. Family relationships were reported as the strongest motivator along with social support and potential health benefits. Findings highlight the unique experience of high-risk workers with physical activity. The findingsunderscore the need to design and implement effective interventions specifically designed to meet the needs of high-risk employees.

    To investigate associations between the number of physical activity facilities within walking distance of school and physical activity behavior in 12th grade girls during after-school hours. Girls (N=1394) from 22 schools completed a self-report to determine physical activity after 3:00 p.m. The number of physical activity facilities within a 0.75-mile buffer of the school was counted with a Geographic Information System. Associations between the number of facilities and girls' physical activity were examined using linear mixed-model analysis of variance. Overall, girls who attended schools with ≥5 facilities within the buffer reported more physical activity per day than girls in schools with schools with ≥5 facilities reported ∼12% more physical activity per day than girls who attended rural schools with schools with ≥5 vs. school siting decisions are made, the number of physical activity facilities surrounding the school should be considered to encourage physical activity in 12th grade girls.

    Full Text Available The aim of the study was to investigate the constraints that prevented the young people who studied at high schools from participating in leisure time physical activities. The population of the study was composed of the students who studied at high schools in Afyonkarahisar Province. Method of population selection and sample recruitment was purposive sampling. 783 volunteers participated in the study. It was seen that some of the answers were invalid and therefore, sample was made up by 750 participants [14 - 18 age (x=15.77, sd=1.05, 64.9% (487 of them female students]. As the data collection tool; Leisure Time - Physical Activity Constraints (LTPA - C developed by Öcal (2012 was used. The scale is composed of 8 subscales: body perception, facilities, income, family, skill perception, time, willpower and society. It is a 6 - point Likert type scale and measures participants‟ physical activity participation status in their leisure times. For the analyses of the data; descriptive statistics, univariate analysis of variance (ANOVA and Independent Samples T - Test were used. According to the study findings; it was found out that there were significant differences among the participants in terms of the scores of LTPA - C as far as participants‟ genders, parental educatio nal status, maternal professional status, school types and grades (p<0.05.

    Identifying multi-level factors affecting physical activity (PA) levels among adolescents is essential to increasing activity to promote health within this population. This study examines the associations between PA and 11 independent factors among Manitoba high school students. The sample included 31,202 grade 9-12 students who completed the Manitoba Youth Health Survey. Associations between PA and independent factors were examined separately and through multivariate regression. Analyses were stratified by gender. Perception of athletic ability, school location, parental encouragement and number of active friends were strong predictors of activity for moderately active and active males and females. Grade was a significant predictor of PA for females at both levels of activity but only significant for males when comparing active to inactive students. Perception of schoolwork and means of transport were minimally associated with PA. Results highlight the importance of targeting multiple levels of influence to increase PA among youth. Programs should focus on older students, females and those who are inactive or moderately active. In addition, social modeling of PA and increasing self-efficacy around activity should be encouraged.

    While the prevalence of overweight and obesity among children continues to grow nationally, prevalence in the North-East of England is among the highest in the UK. The objective of this study was to investigate the habitual physical activity levels in a particularly obesogenic environment in the North-East of England. Eight primary schools were selected using a stratified random sampling frame ranking average deprivation levels. Participating children (n = 246, mean age 10 years) wore an accelerometer (Actigraph, GT-256) over five consecutive days (weekend plus three weekdays). Total daily moderate-to-vigorous intensity physical activity was calculated using thresholds by Puyau and colleagues. Only 7% (17/246) of children were sufficiently active. Boys were more physically active than girls (766 +/- 268 vs. 641 +/- 202 counts/min, 95% CI for the difference 63-186 cpm.). Total physical activity was not influenced significantly by deprivation levels or weight status, and there were no significant differences in physical activity between school or weekend days. The North-East of England is a recognized 'hot spot' for paediatric obesity and the present study shows that low levels of habitual physical activity are typical. Choice of accelerometry threshold affects both the apparent amount of physical activity and the ability to detect groups with particularly low levels of physical activity.

    Recent studies indicate that physically demanding work is a risk factor for heart disease among men, especially those with low or moderate physical activity during leisure time. Among women, present evidence is inconclusive. The design was a prospective cohort study. This investigation in the Danish Nurse Cohort Study included 12,093 female nurses aged 45-64 years, who answered a self-report questionnaire on physical activity at work and during leisure time, known risk factors for ischaemic heart disease (IHD) and occupational factors at baseline in 1993. Information on the 15-year incidence of IHD was obtained by individual linkage in the National Register of Hospital Discharges to 2008. During follow-up 580 participants were hospitalised with IHD. A significant interaction between occupational and leisure time physical activity was found with the lowest risk of IHD among nurses with the combination of moderate physical activity at work and vigorous physical activity during leisure time. Compared to this group high physical activity at work was associated with a higher risk of IHD at all levels of physical activity during leisure time increasing from hazard ratio 1.75 (95% confidence interval (CI) 1.10-2.80) among nurses with vigorous physical activity during leisure time to 2.65 (95% CI 1.44-4.88) among nurses being sedentary during leisure time. This study among Danish nurses suggests that high physical activity at work is a risk factor for IHD among women. Vigorous physical activity during leisure time lowered but did not completely counteract the adverse effect of occupational physical activity on risk of IHD. © The European Society of Cardiology 2014.

    The 2008 Physical Activity Guidelines recommend youth participate in a variety of physical activities; however, few nationally representative studies describe the types and variety of youth activity. This study assessed the most frequently reported types and variety of activities among U.S. high school students, and examined the association between variety and meeting the 2008 Guidelines for aerobic activity (aerobic guideline). We analyzed data on 8628 U.S. high school students in grades 9-12 from the 2010 National Youth Physical Activity and Nutrition Survey. Types of physical activity were assessed by identifying which activities each student reported in the past 7 days. Variety was assessed by the total number of different activities each student reported. Percentage (95% CI) of students who reported engaging in each activity was assessed. Logistic regression was used to examine the association between variety and meeting the aerobic guideline. Walking was the most frequently reported activity among U.S. high school students. On average, students reported participating in 6 different activities. Variety was positively associated with meeting the aerobic guideline. These findings support encouraging youth to participate in many physical activities and may be useful for developing interventions that focus on the most prevalent activities.

    Full Text Available DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n5p567   In an attempt to understand the problem of declining physical activity (PA among adolescents, there has been an increasing interest in identifying perceived barriers (PB that can reduce the involvement of adolescents in PA. The aim of this study was to identify PB to PA practice among public high school students. The samples was composed of 348 students aged 14-19 years, 46.8% females and 53.2% males. To investigate BP, an instrument consisting of 12 statements and validated for the study population was used. The analysis of results was carried out by descriptive statistics, Kruskal Wallis test to check the possible differences in PB throughout high school years and chi-square for the difference in proportions of barriers. Having many tasks to do, lack of time and adverse weather conditions were the most cited PB. There was no difference in the perception of barriers among high school years (males: p = 0.44; females: p = 0.23. PB “not having how to go or return” (p = 0.04, “adverse weather conditions” and “laziness” (p = 0.02, “lack of time” (p = 0.01 and “at home nobody performs PA” (p = 0.04 showed statistically significant differences between sexes. Both sexes reported similar barriers; however, girls reported higher number of PB and with greater frequency. Identifying which PB prevent the adoption of a physically active lifestyle may be the beginning of solutions to minimize the negative effects.

    Purpose While girls are generally less physically active than boys, some girls regularly engage in high levels of physical activity (PA); however, very little is known about these girls and how they differ from those who are less physically active. This study examined the PA behavior and related characteristics of highly-active adolescent girls and compared them with those who are less active. Methods Data from 1,866 8th grade girls from 6 field centers across the U.S. participating in the Trial of Activity for Adolescent Girls (TAAG) were included in the present analysis. Mixed model ANOVAs examined differences in sociodemographic, anthropometric, psychosocial, and physical activity (accelerometry and self-report) variables between high- and low-active girls; effect sizes were calculated for the differences. Results High-active girls were taller, had lower BMIs and body fat, and were less sedentary. High-active girls scored higher on self-efficacy, enjoyment of PA, self-management strategies, outcome-expectancy value, and support from family and friends than low-active girls. Low-active girls participated in more leisure-time and educational sedentary activities than high-active girls. High-active girls participated in more PA classes/lessons outside of school, team sports, and individual sports. They were also more likely to participate in sports in an organized setting in the community or at school than low-active girls. Conclusions Health promotion efforts should focus on decreasing the amount of time girls spend in sedentary activities and replacing that time with organized PA opportunities; such efforts should seek to minimize perceived barriers and increase self-efficacy and support for PA.

    Background Federal guidelines state that youth should participate in a variety of physical activity (PA) they find enjoyable. Little is known, however, about how variety and enjoyment are associated with PA participation among adolescents. Methods Data came from the 2010 National Youth Physical Activity and Nutrition Survey, a nationally representative survey of adolescents. Path analysis was used to examine the association of a variety of self-reported PA, defined as the number of activities and activity types (ie, team sports/weightlifting, individual activities, and other competitive/recreational sports), on self-reported PA enjoyment and participation. The analysis also examined whether enjoyment mediates the association between a variety of PA and participation. Separate models were estimated for boys and girls. Results Number of activities was associated with increased PA enjoyment and participation. For boys and girls, team sports/weightlifting was associated with increased participation, and individual activities were indirectly associated with increased participation through enjoyment. For boys, team sports/weightlifting was indirectly related with participation. Conclusions These findings suggest that participation in a variety of PA is associated with increased PA enjoyment and participation. Providing opportunities for adolescents to engage in a variety of activities might help them identify PA they enjoy and facilitate lifelong PA habits. PMID:26107142

    Background Variability exists in children’s activity patterns due to the association with environmental, social, demographic, and inter-individual factors. This study described accelerometer assessed physical activity patterns of high and low active children during segmented school week days whilst controlling for potential correlates. Methods Two hundred and twenty-three children (mean age: 10.7 ± 0.3 yrs, 55.6% girls, 18.9% overweight/obese) from 8 north-west England primary schools wore ActiGraph GT1M accelerometers for 7 consecutive days during autumn of 2009. ActiGraph counts were converted to minutes of moderate (MPA), vigorous (VPA) and moderate-to-vigorous (MVPA) physical activity. Children were classified as high active (HIGH) or low active (LOW) depending on the percentage of week days they accumulated at least 60 minutes of MVPA. Minutes spent in MPA and VPA were calculated for school time and non-school time and for five discrete school day segments (before-school, class time, recess, lunchtime, and after-school). Data were analysed using multi-level modelling. Results The HIGH group spent significantly longer in MPA and/or VPA before-school, during class time, lunchtime, and after-school (P school level factors. The greatest differences occurred after-school (MPA = 5.5 minutes, VPA = 3.8 minutes, P active children achieved significantly more MPA and VPA than LOW active during four of the five segments of the school day when analyses were adjusted for potential correlates. Physical activity promotion strategies targeting low active children during discretionary physical activity segments of the day, and particularly via structured afterschool physical activity programs may be beneficial.

To evaluate physical activity as a measure of control of arterial hypertension in adults older than 30 years who perform an exercise routine in a period of time and compare these to establish whether or not there is a control of their pressure, from the Municipality of San Agustín Metzquititlán, Hidalgo, Mexico. Material and methods. Descriptive observational epidemiological study in 100 people over 30 years of age, 43 men and 57 women before and after their exercise routine in the municipality of San Agustín Metzquititlán, Hidalgo, Mexico. Results. 94% of the population reported that physical activity helps them maintain control over blood pressure, and thereby prevent the progression of symptoms that hypertension expresses, although the changes were not significant with a value of P> .05. Conclusion. Physical activity is effective as a non-pharmacological treatment in the reduction of arterial hypertension; however, obesity and toxic- food habits attenuate the improvement of the patients' health, not to modify these, it is negative. For anything positive exercise if no significant changes in these.

    Full Text Available Highly intensive physical activity is the most effective for men’s health protection. In modern life conditions its level is insufficient. It requires organism’s appropriate physical activity, which is determined by way of life. Especially important it is before trainings. Purpose: to study special aspects of different intensity’s physical activity; of eating special food and sleeping regime of mature men before their highly intensive physical trainings. Material: in experiment men (n=26, age - 35-53years, who practice healthy life style and independent physical activity of high intensity, participated. We used bio-register Basis B1. Every day we registered: Peak - physical activity of different intensity; duration and quality of sleep; relative weight of consumed food. Besides, we calculated body mass index and physical condition. The study was conducted during 30 days in winter period. The following results were compared: indicators before not planned physical activity and average-monthly indicators. Results: Before arbitrary physical functioning we found in men: confident weakening of average intensity (by 9-11% and low intensity (by 10% physical activity; confident increase of consumed food’s relative weight (by 6.82%, vegetarian food (by 10.64% and raw food (by 7.61%; confident reduction of animal origin food (by 8.7%. No changes were found in duration and quality of sleep before highly intensive physical functioning. Conclusions: specific features of mature men’s way of life before their not planned highly intensive physical functioning are as follows: reduction of general physical activity; increase of consumed food. These factors facilitate energy accumulation in organism for its realization in highly intensive physical functioning the next day.

    Several studies have shown that physical activity levels have declined in many countries, even with the regular practice of physical education in schools. The purpose of this study was to identify the prevalence of low physical activity levels and associated factors in adolescents enrolled in public high schools in Northeastern Brazil. The sample was composed of 2259 adolescents (62.3% female) aged 16.26 ± 1.1 years. A questionnaire was applied to collect data on physical activity levels, sociodemographic information, tobacco use and alcohol consumption, nutritional status and sedentary behavior. Descriptive statistics and Poisson regression hierarchized model with Prevalence Rate (PR) and P ≤ .05 were used. Higher prevalence of low physical activity level (89.1%) was observed. It was observed that 19.6% of individuals did not attend physical education classes regularly. Association was identified between low physical activity level and older girls (P = .02) and not attending physical education classes (P physical activity level was those whose parents studied until three years (P = .04). Low physical activity level was present in most adolescents, more evident in girls. Lifestyle changes are needed, with substitution of sedentary activities for physical and sport activities in schools.

    [Purpose] This study aimed to compare physical activities between junior high school and high school female football players in order to explain the factors that predispose to a higher incidence of sports injuries in high school female football players. [Subjects and Methods] Twenty-nine female football players participated. Finger floor distance, the center of pressure during single limb stance with eyes open and closed, the 40-m linear sprint time, hip abduction and extension muscle strength and isokinetic knee flexion and extension peak torque were measured. The modified Star Excursion Balance Test, the three-steps bounding test and three-steps hopping tests, agility test 1 (Step 50), agility test 2 (Forward run), curl-up test for 30 seconds and the Yo-Yo intermittent recovery test were performed. [Results] The high school group was only significantly faster than the junior high school group in the 40-m linear sprint time and in the agility tests. The distance of the bounding test in the high school group was longer than that in the junior high school group. [Conclusion] Agility and speed increase with growth; however, muscle strength and balance do not develop alongside. This unbalanced development may cause a higher incidence of sports injuries in high school football players.

  6. Declining Physical Activity and Motivation from Middle School to High School.

    2018-01-02

    To determine whether naturally-occurring changes in intrinsic motivation, behavioral regulation, and goals mitigate declining physical activity among adolescents. Latent growth modeling was applied in tests of change in intrinsic motivation, facets of behavioral regulation, and their interactions with goals on change in physical activity measured by accelerometer in a cohort of 260 boys and girls evaluated longitudinally from 6th through 9th grades. Physical activity declined less in youths who maintained higher intrinsic motivation or integrated regulation, but only when they maintained higher enjoyment goal compared to other students. Physical activity also declined less in students who maintained higher intrinsic motivation or integrated motivation and had bigger declines in appearance goal (or social and competence goals with intrinsic motivation) compared to students who maintained higher levels of those goals. The interactions correspond to 1 to 2 min per hour less decrease in physical activity. Consistent with Self-determination Theory, the findings encourage interventions that target autonomous motivation among youths. The results extend prior evidence in three ways. First, the cohort was tracked for three years using an objective measure of physical activity. Second, influences of intrinsic motivation and integrated regulation on changing physical activity were not direct. They interacted with changing goals, indicating that interventions should also focus on specific goals for physical activity as effect modifiers. Third, interventions focused on autonomous motivation should consider that controlled, introjected motivation may also interact with goals to influence on physical activity during the transition between middle school and high school.

    According to theory, girls who set goals about increasing their physical activity and who are dissatisfied with their current activity level are likely to form intentions to be active and to carry out those intentions, especially if they have high efficacy and control beliefs about being physically active. We tested those ideas while observing naturally occurring change during high school. A cohort of 431 black and white girls was tested at the end of their 9th- and 12th-grade academic years. Confirmatory factor analysis established the structural invariance of the measures across the 3-year study period. Structural equation modeling and panel analysis were used to determine whether changes in goal setting and satisfaction would mediate relations of self-efficacy and perceived behavioral control with changes in intention and physical activity. Testing occurred between February and May in 1999 and 2004. Data were analyzed in 2006. Goal setting and intention mediated the indirect relation between self-efficacy and change in physical activity. Perceived behavioral control and physical activity change were related directly and also indirectly by a path mediated through satisfaction and intention. Black girls had lower self-efficacy, but changes in other variables were unrelated to race. These observations of longitudinal relations elaborate application of self-efficacy theory and the theory of planned behavior to physical activity by showing that goal setting and satisfaction mediate the relations of self-efficacy and perceived behavioral control with changes in intention and physical activity. The results encourage additional research to identify the sources and development of physical activity goals, and their attainment, among girls, and whether experimental manipulation of goals and intentions can mitigate the decline in girls' physical activity during high school.

    2017-02-01

    Past research in social and health psychology has shown that affiliation motivation is associated with health behavior, especially for high-risk populations, suggesting that targeting this motivation could be a promising strategy to promote physical activity. However, the effects that affiliation appeals (e.g., pictures depicting companionship during physical activities) and accompanying slogans have on motivating physical activity have been largely unexplored. Hence, our two studies experimentally tested the effects of exposure to affiliation-based pictures for overweight or less active people, as well as the moderating effect of affiliation motivation. The results of these two studies give some indication that group pictures (with or without an accompanying slogan) can be an effective strategy to improve high-risk populations' attitudes, self-efficacy, and intentions to engage in physical activity. Affiliation motivation as a personality trait did not interact with these effects, but was positively associated with attitudes, independent of the group picture effect.

    Although physical activity can help mitigate or prevent multiple chronic diseases, most people in the U.S., especially high-poverty minority groups, engage in insufficient levels of physical activity. To test ways to promote more physical activity in high-poverty area public parks we conducted a randomized controlled intervention trial. After completing baseline measures of park-based physical activity using systematic direct observation three times/day each month for six months and assessing preferences for park programming among 1445 residents living within 1 mile of study parks, we randomized 48 parks in high poverty neighborhoods in the City of Los Angeles, California during 2013-2014 to four study arms: 1) free physical activity classes over a 6-month period, 2) a frequent user program where participants could win prizes based upon the number of visits they made to the park, 3) both the programs, and 4) neither one (control condition). We re-measured park use in 2014-2015 using the same methods during the six months the intervention programs were in operation. A total of 2047 free park classes were offered attracting 16,718 participants. The frequent user programs enrolled 1452 individuals and prizes were awarded to 830. Residents in the two study arms with free classes were more likely to report being aware of and participating in park-based physical activity programs; however, overall observed park-based physical activity increased similarly across all study arms. The process evaluation uncovered several barriers to program implementation, including inconsistent scheduling of classes, partly due to safety concerns among instructors. Multiple social factors interfere with leisure time physical activity among low-income populations, suggesting modest interventions may be insufficient to overcome these issues. Although new park programs can attract users, new programs alone may be insufficient to increase overall park use in low-income neighborhoods at times

    To determine if the physical design and organizational structure of rehabilitation units is related to the amount of patients' motor activity. An observational study was conducted; time samples of the motor activity of patients following stroke were taken between 7AM and 7PM both on weekdays and weekends. Two rehabilitation units associated with general hospitals with different physical design and organizational structure. One unit was spread over a large area and had a highly organized daily structure; the other was small and informally organized. Inpatients with hemiplegia as a result of stroke who gave consent to participate. The nature and frequency of 14 motor activities were compared between units. No significant difference was found in any of the observed motor activities between the units when using independent groups t tests (p = 0.1-0.8). Subjects in both units spent more than 70% of their day in activities largely unrelated to physical outcome (eg, conversing with visitors or doing nothing observable) and less than 20% of the day in activities that could potentially contribute to their recovery (eg, in therapy or exercising independently). Rehabilitation units are not functioning as learning environments. The challenge is to identify and implement measures that will change this finding.

The aim of this review is to provide clinicians and clinical scientists with an overview of the current state of the literature describing the negative influence of obesity on blood pressure and it’s determinants in children. In short, we discuss the array of vascular abnormalities seen in overweight children and adolescents, including endothelial dysfunction, arterial stiffening and insulin resistance. We also discuss the potential role of an increased activation of the sympathetic nervous system in the development of high blood pressure and vascular dysfunction associated with obesity. As there is little consensus regarding the methods to prevent or treat high blood pressure in children, we also provide a summary of the evidence supporting relationship between physical activity and blood pressure in children and adolescents. After reviewing a number of physical activity intervention studies performed in children, it appears as though 40 minutes of moderate to vigorous aerobic-based physical activity 3–5 days/week is required to improve vascular function and reduce blood pressure in obese children. Future studies should focus on describing the influence of physical activity on blood pressure control in overweight children.Keywords: arterial compliance, insulin sensitivity, aerobic exercise, sympathetic nervous system

    Previous studies have found that higher physical activity levels are associated with greater academic achievement among students. However, it remains unclear whether associations are due to the physical activity itself or sports team participation, which may involve requirements for maintaining certain grades, for example. The purpose of this study is to examine the associations between sports team participation, physical activity, and academic outcomes in middle and high school students. Data were drawn from Project EAT (Eating Among Teens), a survey of middle and high school students (n = 4746). Students self-reported their weekly hours of physical activity, sports team participation, and academic letter grades. Two statistical models were considered: first, 2 separate regression analyses with grade point average (GPA) as the outcome and either sports team participation or physical activity as the predictor; second, a single regression with GPA as the outcome and both sports team participation and physical activity as the simultaneous predictors. For high school girls, both physical activity and sports team participation were each independently associated with a higher GPA. For high school boys, only sports team participation was independently associated with a higher GPA. For middle school students, the positive association between physical activity and GPA could not be separated from the relationship between sports team participation and a higher GPA. Regardless of whether academic success was related to the physical activity itself or to participation on sports teams, findings indicated positive associations between physical activity involvement and academic achievement among students.

    2011-02-01

    Research sought to identify combinations of risk and protective factors predicting change in physical activity (PA) over one year in high school students. Adolescents (N = 344; M = 15.7 years) participated in a longitudinal study with assessment of demographics, substance use/smoking exposure, height and weight, psychological factors, and PA in 10th and 11th grade. PA participation in 11th grade was greatest for adolescents who engaged in PA and had high sports competence (78%), and least for adolescents who did not engage in or enjoy PA (13%) in 10th grade. Identifying adolescent subgroups at risk for decreasing PA can inform the development of tailored interventions.

    A high-caloric intake combined with a sedentary lifestyle is an important player in the development of type 2 diabetes mellitus (T2DM). The present study was undertaken to examine if the level of physical activity has impact on the metabolic effects of a high-caloric (+2,000 kcal/day) intake. Therefore, healthy individuals on a high-caloric intake were randomized to either 10,000 or 1,500 steps/day for 14 days. Step number, total energy expenditure, dietary records, neuropsychological tests, maximal oxygen uptake (Vo2max), whole body dual-energy X-ray absorptiometry (DXA) and abdominal magnetic resonance imaging (MRI) scans, continuous glucose monitoring (CGM), and oral glucose tolerance tests (OGTT) with stable isotopes were performed before and after the intervention. Both study groups gained the same amount of body weight. However, the inactive group accumulated significantly more visceral fat compared with the active group. Following the 2-wk period, the inactive group also experienced a poorer glycemic control, increased endogenous glucose production, decreased hepatic insulin extraction, increased baseline plasma levels of total cholesterol and LDL, and a decreased cognitive function with regard to capacity of attention. In conclusion, we find evidence to support that habitual physical activity may prevent pathophysiological symptoms associated with diet-induced obesity.

    Background Evidence from developing countries is limited on how income level for a given neighborhood is related to physical activity among its residents. Purpose The goal of the study was to examine the association between walkability and physical activity outcomes, and the effect of income on the relationship between walkability and physical activity in adults. Methods The Spaces for Physical Activity in Adults Study (ESPACOS Project) took place in Curitiba, Brazil. Data were collected in 2010 in 32 census tracts selected to vary in income and walkability, as measured by GIS. Participants were 697 individuals aged 18–65 years (52.0% were women) randomly sampled from the selected neighborhoods. The International Physical Activity Questionnaire was used to measure physical activity. All analyses were conducted in 2012. Results The proportion of those who walked for transportation for ≥150 minutes/week was 21.1% in low-walkability areas, and ranged from 33.5% to 35.0% in high-walkability areas. A total of 12.6% of residents were found to walk for leisure for ≥150 minutes/week; this result did not vary across quadrants of walkability and income level. The prevalence of leisure-time moderate-to-vigorous physical activity (MVPA) was 7.1–10.5 percentage points higher in high-compared to low-walkability areas. After adjusting for all individual confounders, walkability showed an independent association with walking for transport (OR=2.10, 95% CI=1.31, 3.37, p=0.002) and leisure-time MVPA (OR=1.57; 95% CI=1.06, 2.32; p=0.024). Neighborhood income level was independently associated with leisure-time MVPA (OR=1.70; 95% CI=1.06, 2.74, p=0.029). No association was found between walkability and walking for leisure. No interaction was found between walkability and neighborhood income level. Conclusions This study, among adults living in Curitiba, Brazil, confirms findings from studies of high-income countries showing that walkability is positively associated with

    The focus of the PhenX (Phenotypes and eXposures) Toolkit is to provide researchers whose expertise lies outside a particular area with key measures identified by experts for uniform use in large-scale genetic studies and other extensive epidemiologic efforts going forward. The current paper specifically addresses the PhenX Toolkit research domain of physical activity and physical fitness (PA/PF), which are often associated with health outcomes. A Working Group (WG) of content experts completed a 6-month consensus process in which they identified a set of 14 high-priority, low-burden, and scientifically supported measures. During this process the WG considered self-reported and objective measures which included the latest technology (e.g., accelerometers, pedometers, heart-rate monitors). They also sought the input of measurement experts and other members of the research community during their deliberations. A majority of the measures include protocols for children (or adolescents), adults, and older adults or are applicable to all ages. Measures from the PA/PF domain and 20 other domains are publicly available and found at the PhenX Toolkit website, www.phenxtoolkit.org. The use of common measures and protocols across large studies enhances the capacity to combine or compare data across studies, benefitting both PA/PF experts and non-experts. Use of these common measures by the research community should increase statistical power and enhance the ability to answer scientific questions that might have previously gone unanswered.

    The aim of this study was to examine how vigorous physical activity (recreational physical activity) (VPA) and moderate to vigorous physical activity as a part of daily life (MVPA) is associated with structural characteristics (availability of sports facilities and sports clubs with child members) in Greenlandic adolescents. Data from the 2006 Health Behaviour in School-aged Children survey including 2,430 children aged 11-17 years was used. Logistic regression models were developed with dichotomous measures on VPA and MVPA as outcomes, number of indoor sports facilities and of sports clubs with child members as independent variables, and adjusted for age, gender, family affluence (FAS), and type of habitation (capital, town or village). High VPA increased with access to indoor facilities, while high MVPA was less likely (odds ratio (OR) 0.54 (0.42-0.70)) if indoor sports facilities were present, both unadjusted and adjusted. Access to a local sports club increased OR for high VPA both unadjusted and adjusted to about 2.3 for five or more clubs, while access to sports clubs was not associated with unadjusted MVPA, negatively associated if adjusted for age, gender and FAS but positively associated if also adjusted for indoor sports facilities. Access to indoor sports facilities itself had a positive association with high VPA, but was persistently negatively associated with high MVPA. Presence of sports clubs with child members was positively associated with high VPA while the association with high MVPA was more complex. The findings have implications for public health planning.

    This study investigated associations of violence-related behaviors with physical activity (PA)-related behaviors among U.S. high school students. Data from the 2009 national Youth Risk Behavior Survey, a cross-sectional survey of a nationally representative sample of 9th-12th grade students, were analyzed. Sex-stratified, adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated for associations between violence-related behaviors and being physically active for ≥60 minutes daily, sports participation, TV watching for ≥3 hours/day, and video game/computer use for ≥3 hours/day. Among male students, at-school bullying victimization was negatively associated with daily PA (aOR: 0.72; 95% CI: 0.58-0.87) and sports participation; skipping school because of safety concerns was positively associated with video game/computer use (1.42; 1.01-2.00); and physical fighting was positively associated with daily PA. Among female students, at-school bullying victimization and skipping school because of safety concerns were both positively associated with video game/computer use (1.46; 1.19-1.79 and 1.60; 1.09-2.34, respectively), and physical fighting at school was negatively associated with sports participation and positively associated with TV watching. Bullying victimization emerged as a potentially important risk factor for insufficient PA. Schools should consider the role of violence in initiatives designed to promote PA.

    The purpose of this study was to examine the role of goal orientation, motivational climate, and dispositional flow in physical education lessons on extracurricular involvement in physical activity. Questionnaires were administered to 1,103 (792 athletes; 311 nonathletes) secondary school students (M age = 14.3 yr., SD = 0.7). Analysis showed significant mean differences between groups on goal orientation and dispositional flow in physical education lessons, but none for perception of motivational climate. These findings suggest that dispositional variables are related to extracurricular involvement in physical activity.

    To analyze the association between perceived neighborhood environment and physical activity (PA) in high school students from Curitiba (PR), Brazil. A sample of 1,611 high school students from public schools was surveyed. The PA was assessed through questions, engaged for at least 20 minutes or 60 minutes. Perceptions on neighborhood environment were assessed through ten questions about neighborhood characteristics. Gender, age and number of cars in the household were self-reported and used as confounding variables. Absolute and relative frequencies were used in the sample, and associations were tested through adjusted logistic regressions for the confounding variables and stratified by gender (p perception of the environment was associated to PA practice among boys and girls in this sample. The results suggest that some environmental characteristics which make neighborhoods more attractive could be related to PA among adolescents.

    Among the different porous materials, activated carbon (AC) is the most widely used for environmental applications such as gas-phase pollutant removal, gas separation, solvent recovery and water purification, because of its high specific surfacea. Commercial activated carbons are generally produced from coals and lignocellulosic materials [1]. Additionally, in the latest years great attention is being focused on the reuse of wastes such as sewage sludges [2,3]. The objective of this study is to find more effective activating procedures to prepare AC from sewage sludge. Both dried sludges from two different WWTP (SL, SB) and their corresponding chars prepared by pyrolysis (SL-P, SB-P) were activated using physical activation (CO{sub 2}) and chemical activation (H{sub 3}PO{sub 4}, NaOH and KOH). As shown in Table 1, pyrolysis of the raw sludges slightly increased the specific surface area, up to 50 m{sup 2}/g. Acid-washing of the pyrolyzed samples with 5 M HCl removes part of the metal content leading to an increase in the specific surface areas for both SL-PD and SB-PD, with surface areas of 428 m{sup 2}/g and 188 m{sup 2}/g, respectively. This simple washing treatment is useful for the development of porous adsorbents, especially in the case of SL derived materials. Our results show that CO{sub 2} physical activation of the pyrolyzed and the HCl-washed samples develops no appreciable porosity in the final materials, under the experimental conditions used. For CO{sub 2} activation, maximum temperatures of 870 C and holding times up to 4 hours in CO{sub 2} (100 ml/min) were used. Chemical activation with H{sub 3}PO{sub 4} of the pristine samples and those pyrolyzed was performed at 450 C, a temperature typically used for the activation by H{sub 3}PO{sub 4} of lignocellulosic precursors, and using two different H{sub 3}PO{sub 4} solutions (30 and 50% wt). These conditions were not either suitable for an efficient porosity development. A detailed study about the

    Physical activity (PA), sedentary behaviors, and dietary behaviors are each associated with overweight and obesity among youth. However, the associations of PA and sedentary behaviors with dietary behaviors are complex and not well understood. To describe the associations of PA and sedentary behaviors with dietary behaviors among a representative sample of US high school students. We analyzed data from the 2010 National Youth Physical Activity and Nutrition Study (NYPANS). Using logistic regression models which controlled for sex, race/ethnicity, grade, body weight status, and weight management goals, we compared dietary behaviors among students who did and did not meet national recommendations for PA and sedentary behaviors. Students who participated in recommended levels of daily PA (DPA) and muscle strengthening PA (MSPA) were more likely than those who did not to eat fruits and vegetables. Students who exceeded recommended limits for television (TV) and computer/video game (C/VG) screen time were less likely than those who did not to consume fruits and vegetables and were more likely to consume fast food and sugar-sweetened beverages. Researchers may want to address PA, sedentary behaviors, and dietary behaviors jointly when developing health promotion and obesity prevention programs for youth.

    2016-10-01

    The aim was to estimate the prevalence of stages of change for physical activity and associated sociodemographic factors in students. The sample consisted of 942 students (44.7% males, 55.3% females; mean age = 16.1 years, SD = 1.1) in southern Brazil. Self-administered questionnaire was applied to identify stages of behavioral change for physical activity and sociodemographic variables (gender, age, maternal schooling, economic status, and school shift). Multinomial logistic regression was used to estimate the odds ratio (95%). Results showed that 9.6% were in the pre-contemplation stage, 18.4% in the contemplation, 17.6% in the preparation, 14.3% in the action, and 39.6% in the maintenance stages. Girls and adolescents with lower economic status were more likely to be at stages of behavioral risk. Students whose mothers had high education were more likely to be in the action stage. © The Author(s) 2016.

    Physical activity can be a valuable countermeasure to sarcopenia in its treatment and prevention. In considering physical training strategies for sarcopenic subjects, it is critical to consider personal and environmental obstacles to access opportunities for physical activity for any patient with chronic disease. This article presents an overview of current knowledge of the effects of physical training on muscle function and the physical activity recommended for sarcopenic patients. So that this countermeasure strategy can be applied in practice, the authors propose a standardized protocol for prescribing physical activity in chronic diseases such as sarcopenia.

    2016-01-01

    Objectives To understand parents’ perspectives of their preschoolers’ physical activity behaviours. Methods A maximum variation sample of 71 parents explored their preschoolers’ physical activity behaviours through 10 semi-structured focus group discussions. Results Parents perceived Canada’s Physical Activity Guidelines for Children as inadequate; that their preschoolers get and need more than 30–90 minutes of activity daily; and that physical activity habits must be established during the preschool years. Nine barriers against and facilitators toward adequate physical activity were proposed: child’s age, weather, daycare, siblings, finances, time, society and safety, parents’ impact, and child’s activity preferences. Discussion The need for education and interventions that address current barriers are essential for establishing physical activity as a lifestyle behaviour during early childhood and, consequently, helping to prevent both childhood and adulthood obesity.

    Full Text Available DOI: http://dx.doi.org/10.5007/1980-0037.2017v19n1p62   Sedentary behavior may play an important role for health outcomes, regardless of the amount of physical activity in daily life (PADL.We aimed to evaluate and compare sedentary behavior as well as physical capabilities in physically active smokers and non-smokers. Twenty-eight adult smokers and 38 non-smokers free of lung disease were matched for age, sex, body mass index, body composition, cardiovascular risk and moderate-to-vigorous PADL. Participants underwent spirometry, cardiopulmonary exercise test (CPET, six-minute walk test (6MWT, isokinetic dynamometry, and body composition (bioelectrical impedance.Despite the similar amount of moderate-to-vigorous PADL(median, 4.5h/week for smokers and 4.0h/week for non-smokers, smokers spent more time lying (median, 8.2h/week: 95% confidence interval, 5.4 to 19.1 vs. 6.1h/week: 3.7 to 11.2 and in sedentary activities (median, 100h/week: 66 to 129 vs. 78h/week: 55 to 122 compared to non-smokers. Smokers also presented worse spirometry, peak V’O2 and maximum heart rate in the CPET, 6MWT, and isokinetic indices (p<0.05. We observed a strong correlation between the time spent lying and spirometry (r = - 0.730 in smokers. Smoking is related to higher sedentary behavior, despite the suitable PADL. An appropriate PADL did not reduce the deleterious effects of smoking on physical capabilities. Interrupting sedentary behavior may be an appropriate intervention target in smokers for reducing the risk of diseases.

    The study's purpose was to investigate if physical activity initiated with the start of high-fat feeding would oppose development of endothelial dysfunction, and if it does, then to determine some potential mechanisms. C57BL/6 female mice were randomly divided into three groups: (1) control low-fat diet (LF-SED; 15% of calories from fat), (2) high-fat diet (HF-SED; 45% of calories from fat), and (3) HF diet given access to a voluntary running wheel (HF-RUN). Our hypothesis was that HF-RUN would differ in multiple markers of endothelial dysfunction from HF-SED after 10 weeks of 45%-fat diet, but would not differ from LF-SED. HF-RUN differed from HF-SED in nine determinations in which HF-SED either had decreases in (1) acetylcholine (ACh)-induced and flow-induced vasodilatations in isolated, pressurized coronary arterioles, (2) heart phosphorylated endothelial nitric oxide synthase (p-eNOS/eNOS) protein, (3) coronary arteriole leptin (ob) receptor protein, (4) phosphorylated signal transducer and activator of transcription 3 (p-STAT3/STAT3) protein, and (5) coronary arteriole superoxide dismutase 1 protein; or had increases in (6) percentage body fat, (7) serum leptin, (8) coronary arteriole suppressor of cytokine signalling 3 (SOCS3) protein, and (9) coronary arteriole gp91(phox) protein. Higher endothelium-dependent vasodilatation by ACh or leptin was abolished with incubation of NOS inhibitor N(G)-nitro-l-arginine-methyl ester (l-NAME) in LF-SED and HF-RUN groups. Further, impaired ACh-induced vasodilatation in HF-SED was normalized by apocynin or TEMPOL to LF-SED and HF-RUN. These findings demonstrate multiple mechanisms (eNOS, leptin and redox balance) by which voluntary running opposes the development of impaired coronary arteriolar vasodilatation during simultaneous high-fat feeding.

    Inactivity or insufficient physical activity is risk factor for metabolic or cardiovascular diseases. In most of cases the nature of work of office employees does not require high physical efforts and consists mostly of sitting but the reports on leisure activity of office workers are still lacking. Thus, the aim of the study was to assess physical activity of civil and local administration workers and bank officials. 293 randomly selected office workers took part in the study.

    Adolescent self-rated health is a strong predictor of future illness. In this study we investigated whether physical activity and cardiorespiratory fitness are associated with self-rated health among adolescents aged 16 years. The study sample comprised 7,063 adolescents from the Northern Finland Birth Cohort 1986 (NFBC 1986) who responded to a postal questionnaire in 2001 to 2002. Self-rated health was measured by a single-item question, while physical activity was evaluated by a set of questions concerning the intensity and volume of physical activity outside school hours. Cardiorespiratory fitness was measured with a submaximal cycle ergometer test. Odds ratios (OR) and their 95% confidence intervals (95% CI) for good self-rated health were obtained from multinomial logistic regression. High levels of physical activity (boys: OR 5.50, 95% CI 3.16 to 9.58; girls: OR 4.25, 95% CI 2.37 to 7.61) and cardiorespiratory fitness (boys: OR 1.85, 95% CI 1.05 to 3.24; girls: OR 2.62, 95% CI 1.47 to 4.66) were associated with very good self-rated health in adolescents. High levels of physical activity and cardiorespiratory fitness are positively associated with adolescents' self-rated health. Public health promotion activities that foster physical activity and cardiorespiratory fitness may benefit young people's overall health and well-being.

  10. Fit in 50 years: participation in high school sports best predicts one's physical activity after age 70.

    The health benefits of physical activity are widely established, including decreased risk for disease and improved mental well-being. Yet many children, adolescents, and adults do not meet the minimum recommendations specified in current public health guidelines and physical activity is known to decrease during the life course. The aim of this study was to identify background or personality characteristics that predict whether a healthy 25 year-old would become a physically active 75 year-old. This could have powerful implications for targeting physical activity and health interventions. A unique data set was collected of 712 healthy United States males who passed a rigorous physical exam in the 1940s and who were surveyed 50 years later (in 2000). Their physical activity level after 50 years was correlated and regressed across a wide number of demographic, behavioral, and personality variables from when they were 50 years younger. Data was analyzed in 2012. In contrast to prior beliefs, self-rated personality profile as a young man had little predictive influence on later-life physical activity. Instead, the single strongest predictor of later-life physical activity was whether he played a varsity sport in high school, and this was also related to fewer self-reported visits to the doctor. Encouraging systematic or frequent physical activity at a young age - whether through school sports or club opportunities - might be the best investment in long-term activeness. This is relevant at a time when funding for many sports programs is being eliminated and play time is being replaced with screen time.

    To encourage high school students to meet physical activity goals using a newly developed game, and to document the feasibility, benefits, and challenges of using an electronic gaming application to promote physical activity in high school students. Working with youth and game designers an electronic game, Camp Conquer, was developed to motivate high school students to meet physical activity goals. One-hundred-five high school students were recruited to participate in a 12-week pilot test of the game and randomly assigned to a Game Condition or Control Condition. Students in both conditions received a FitBit to track their activity, and participants in the Game Condition received access to Camp Conquer. Number of steps and active minutes each day were tracked for all participants. FitBit use, game logins, and qualitative feedback from researchers, school personnel, and participants were used to determine intervention engagement. The majority of study participants did not consistently wear their FitBit or engage with the gaming intervention. Numerous design challenges and barriers to successful implementation such as the randomized design, absence of a true school-based champion, ease of use, and game glitches were identified. Developing games is an exciting technique for motivating the completion of a variety of health behaviors. Although the present intervention was not successful in increasing physical activity in high school students, important lessons were learned regarding how to best structure a gaming intervention for the high school population.

    Full Text Available Abstract Background Physical activity (PA rates decline precipitously during the high school years and are consistently lower among adolescent girls than adolescent boys. Due to cultural barriers, this problem might be exacerbated in female Iranian adolescents. However, little intervention research has been conducted to try to increase PA participation rates with this population. Because PA interventions in schools have the potential to reach many children and adolescents, this study reports on PA intervention research conducted in all-female Iranian high schools. Methods A randomized controlled trial was conducted to examine the effects of two six-month tailored interventions on potential determinants of PA and PA behavior. Students (N = 161 were randomly allocated to one of three conditions: an intervention based on Pender's Health Promotion model (HP, an intervention based on an integration of the health promotion model and selected constructs from the Transtheoretical model (THP, and a control group (CON. Measures were administered prior to the intervention, at post-intervention and at a six-month follow-up. Results Repeated measure ANOVAs showed a significant interaction between group and time for perceived benefits, self efficacy, interpersonal norms, social support, behavioral processes, and PA behavior, indicating that both intervention groups significantly improved across the 24-week intervention, whereas the control group did not. Participants in the THP group showed greater use of counter conditioning and stimulus control at post-intervention and at follow-up. While there were no significant differences in PA between the HP and CON groups at follow-up, a significant difference was still found between the THP and the CON group. Conclusion This study provides the first evidence of the effectiveness of a PA intervention based on Pender's HP model combined with selected aspects of the TTM on potential determinants to increase PA among

    High Intensity Interval Training (HIIT) may be effective for accumulating VPA. However, the contribution of HIIT to overall physical activity is unknown. Our primary aim was to explore the impact of school-based HIIT on physical activity. The secondary aim was to explore within-individual changes in physical activity after participating in HIIT. Participants [n = 65; 15.8(0.6)years] were randomized to a HIIT or control group. Intervention groups participated in three HIIT sessions/week. GENEActiv accelerometers assessed objective physical activity at baseline and week-one, to detect changes in MPA and VPA. Intervention effects were examined using linear mixed models and evidence of a change in physical activity (i.e., compensation) were examined using multilevel linear regression models. The group-by-time interaction effects for MPA and VPA were small and moderate, respectively. Adjusted difference between groups for VPA was 1.70 min/day, 95%CI -1.96 to 5.36; p = 0.354; d = 0.55). Embedding HIIT within the school-day had a moderate effect on VPA compared to controls. Compensation analyses (i.e., individual level) suggested that adolescents were more active on days when they participated in HIIT. Further studies are needed to test the effects of HIIT on adolescents' physical activity over extended time periods.

    We determined whether altered physical activity levels might underlie the contrasting adiposity of a divergently selected polygenic murine model of metabolic syndrome (Fat; F) and leanness (Lean; L) mice. We measured physical activity with a long term running wheel experiment and performed an additional high fat diet intervention. Further, we measured posture allocation by visual monitoring within the home cage as a non-exercise correlate of 'normal' physical activity. Whilst initially similar, running wheel activity of the F line declined with age, while the activity of the L line increased. Food intake was higher in the L line and increased with wheel exposure. Vertical rearing measured by video quantification in the home cage, without the stimulus of a running wheel was also significantly higher in the L line. The two lines developed novel alternate strategies to defend their body weight when exposed to high fat diets with a running wheel. F mice increased their running wheel activity, and despite unaltered food intake, still gained weight. L mice reduced their food intake and maintained activity levels without a significant change in body weight. Phenotypic selection for divergence in body fat content has co-segregated with a genetic predisposition for divergent physical activity levels and different strategies for coping with exposure to high fat diets that will facilitate the discovery of the genes underlying these important obesity related traits.

    Full Text Available OBJECTIVE: To analyze the association between perceived neighborhood environment and physical activity (PA in high school students from Curitiba (PR, Brazil. METHODS: A sample of 1,611 high school students from public schools was surveyed. The PA was assessed through questions, engaged for at least 20 minutes or 60 minutes. Perceptions on neighborhood environment were assessed through ten questions about neighborhood characteristics. Gender, age and number of cars in the household were self-reported and used as confounding variables. Absolute and relative frequencies were used in the sample, and associations were tested through adjusted logistic regressions for the confounding variables and stratified by gender (p < 0.05. RESULTS: The adjusted analyses showed that the variables "interesting things" among girls (OR = 1.77; 95%CI 1.05 - 2.96 and "there are places I like" (OR = 2.18; 95%CI 1.33 - 3.58 and "I see people my age", among boys, were associated with PA of at least 20 minutes/day once a week. Additionally, among boys, "I see people my age" was associated with 60-minute (OR = 1.68; 95%CI 1.15 - 2.45. Perceiving the neighborhood environment as "very good" was associated with higher chances of taking up PA among girls (OR = 1.92; 95%CI 1.15 - 3.22 and boys (OR = 3.13; 95%CI 1.97 - 4.97. CONCLUSION: A positive perception of the environment was associated to PA practice among boys and girls in this sample. The results suggest that some environmental characteristics which make neighborhoods more attractive could be related to PA among adolescents.

We analyzed data from the 2010 National Youth Physical Activity and Nutrition Study, a representative sample of US students in grades 9–12. Logistic regression was used to examine associations between PA correlates (obesity, physical education classes, sports team participation, attitude toward PA, adult support for PA, and environmental support for PA and participation in daily PA (DPA, vigorous PA (VPA, muscle-strengthening activity (MSA, viewing television (TV, and using computers or video games (C/VG. A positive attitude toward PA and adult support for PA were both associated with increased PA and decreased sedentary behavior. However, among students who lived in neighborhoods that were not safe for PA, a positive attitude toward PA was not associated with increased DPA or decreased sedentary behavior and was less strongly associated with VPA and MSA. Efforts to increase PA among youth should promote a positive attitude toward PA among youth and encourage adult family members to support their efforts to be active. Policies that promote safe neighborhoods may work synergistically with a positive attitude toward PA to increase participation in PA and decrease sedentary behaviors.

    Childhood physical activity (PA) is an important determinant of health in adults which is influenced by the environment in and outside of home. We aimed to determine the contribution of parental and school factors on student's PA in this study. This cross sectional study was conducted on students attending public and private schools in Hyderabad, Pakistan. A random sample of 246 girls and 255 boys in grade six to ten were selected from ten schools. The PA was assessed through face to face interviews by using the adapted School Health Action Planning and Evaluation System (SHAPES) questionnaire. 40% of the students either walked to or rode on a cycle to travel to their school and 62% students performed individual exercises after school. They spent 6.2 and 5.3 hours on moderate and hard PA per week. About 57% of the mothers and 47% fathers of the students did some mild to moderate exercise 4 times in the week prior to the interview. Students were physically active if they lived in a nuclear family, had believed they had better athletic ability, participated in sports in and out of school and performed moderate exercises (p students' being physically active both within and outside schools.

    Full Text Available Increase of urbanization has pressure on the urban children's lives and physical activities. While in designing of residential apartments’ open spaces, there is little attention to the children. The children, who live in the high-rise apartments found to have less physical activities. However, supposedly, children need to engage in the physical activity in the outdoor areas as WHO recommend that children take part in at least one hour of moderate physical activity in every day. This paper firstly, reviews different researches in this area. Then, it attempts to find children’s satisfaction regarding connectivity to open spaces as a dependent variable and their preferred activities, perceived safety, and familiarity about connectivity to open spaces as independent variables. The method of study is a semi-interview survey with 80 children between 6 and 12 years old (primary school ages in two cases in Tehran. The result of this research shows that children satisfaction from open space has an effect on their outdoor activities. Therefore, the designers should be considering children physical activities needs in open spaces.

    Full Text Available A total of 1,096 adolescents participated in 123 focus groups regarding the perceived outcomes of their involvement in sports and physical activity (PA. The groups, segmented by grade level, sex, and school types, were conducted in both public and private high schools in Montreal, Quebec. We sought to understand, through the participants’ own words, their perception of the outcome matrix of involvement in sports and PA. Focus group questions emphasized changes that adolescents associated with such engagement. In particular, participants were asked how sports and PA might influence behaviors, emotional states, personal characteristics, and other outcomes. Twelve themes were identified in the responses: Positive Health and Physical Changes (18.5%, Activity-Related Positive Emotions (15.6%, and Personal Learning (11.3% were most prevalent in the discussions. A cluster of deeper personal changes thematically described as Self-Identity, Autonomy, and Positive Character Development accounted for another 16.5% of the responses. Relatively few commentaries emphasized negative effects (7.1%. Converting the proportions of qualitative data into a quantitative index allowed us to analyze potential differences in emphasis according to sex, age, and school type. Though a few significant findings emerged, the larger pattern was of a uniform perceptual map across the variables for this adolescent sample. Implications drawn from this investigation highlight the need to clearly articulate concrete pathways to positive nonphysical changes (e.g., mood states, autonomy, positive character development from engagements in sports and PA.

    The accessibility of high active antiretroviral therapy (HAART) for local human immunodeficiency virus (HIV) patients is improving in Rwanda. It is well known that this therapy is associated with serious adverse effects, such as metabolic and morphologic changes. One of the recommended preventive modalities for these complications is participation in physical activity. The current study aims to determine the anthropometric profile and physical activity levels among people living with HIV and receiving HAART in Kigali, Rwanda. The study was a cross-sectional, descriptive quantitative survey. The participant's levels of physical activity participation and their association with anthropometric profiles were measured, using a structured self-administered questionnaire for 407 clients passing through the clinics. Of the participants, approximately 70% were inactive and in addition, 40% were obese and 43% overweight. Obesity was found to be strongly associated with inactivity. Lack of motivation, and time as well as fear of worsening the disease were found to be barriers to participation in physical activity.

    2006-12-01

    Full Text Available In this paper we present findings of an exploratory study, included in a wider investigation which intends to promote meaningful learning of physics concepts, based on experimental work and supported by metacognition tools. The aim of this research was to recognize promoting learning situations in Physics lab. Interviews and questionnaires were applied to teachers and students from four Lisbon high schools. Results show that lab work in physics has a low frequency and, generally, has a demonstration format. Both teachers and students recognize potentialities of lab work to promote learning. Learning is poor when students just observe and/or accomplish commands. Both teachers and students consider the relation theory/experimentation and students doing themselves as fundamental to achieve better learning. In addition to pointing out several problems concerning lab work, teachers envisage it in a very traditional way. So, innovative strategies and methodologies, such as computer use and open-ended problems, pointed by research in science investigation as promoting learning, are left aside.

  17. Physical Activity and Renal Transplantation

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available Renal transplantation is burdened by high cardiovascular risk because of increased prevalence of traditional and disease-specific cardiovascular risk factors and, consequently, patients are affected by greater morbidity and mortality. In renal transplanted patients, healthy lifestyle and physical activity are recommended to improve overall morbidity and cardiovascular outcomes. According to METs (Metabolic Equivalent Task; i.e. the amount of energy consumed while sitting at rest, physical activities are classified as sedentary (<3.0 METs, of moderate-(3.0 to 5.9 METs or vigorous-intensity (≥6.0 METs. Guidelines suggest for patients with chronic kidney disease an amount of physical activity of at least 30 minutes of moderate-intensity activity five times per week (min 450 MET-minutes/week. Data on physical activity in renal transplanted patients, however, are limited and have been mainly obtained by mean of non-objective methods. Available data suggest that physical activity is low either at the start or during renal transplantation and this may be associated with poor patient and graft outcomes. Therefore, in renal transplanted patients more data on physical activity obtained with objective, accelerometer-based methods are needed. In the meanwhile, physical activity have to be considered as an essential part of the medical care for renal transplanted recipients.

    Full Text Available Background. Due to technological development, the average level of physical activity is decreasing among residents of developed countries, which is an important factor in the epidemic of obesity and metabolic syndrome.Results (findings. Although excessive physical exertion disrupts hormonal balance, harms the immune system and somewhat increases the risk of sudden cardiac death, the overwhelming majority of adaptations to regular exercise comprise health benefits. Sensitivity to insulin is increased, metabolism of triglycerides and cholesterol is improved, and the basal tone of the sympathetic nervous system is decreased, which all reduces coronary atherothrombotic events and cardio-vascular mortality. Physical exercise is linked to reduced risk of colon carcinoma, breast cancer and endometrial carcinoma. Regular physical activity prolongs life on average by about two years in comparison with sedentary population, but even more importantly, it preserves endurance and power necessary for independent living well into in advanced age. Physical exercise reduces symptoms of depression and improves the perceived level of satisfaction.Conclusions. In order to achieve the metabolic and psychological benefits of exercise, it is necessary to engage in at least a half hour of moderately intense activity on most days of the week, but daily physical activity is even better.

    Full Text Available Soccer is a favorite sport for  people around the world including in Indonesia. Not only the method of training or talent that will determine the achievement, but the intake of daily nutrients directly proper also provide a positive influence on performance and achievements of athletes. The purpose of this study was to determine the adequacy of nutrition, physical activity, and nutritional status of young men athletes soccer. This study useds cross-sectional method. The number of samples taken as much as 96 athletes from all senior high schools in Denpasar and selected systematic random sampling. Results showed the average level of nutritional adequacy of athletes still in the category of less (<80%. Respectively for energy, carbohydrates, proteins, and fats are 75.95%, 77.24%, 78.96% and 75.83%. If seen the proportion of athletes that sufficient levels of nutrients in enough categories, then each for energy, carbohydrates, proteins, and fats are 58.3%, 57.3%, 51%, and 53.1%. Level of physical activity in athletes only low (56.3% and moderate category (43.8%. Most athletes have normal nutritional status (94.8%, there was only 1% having thin status, and 4.2% had nutritional status of overweight. The advice can be given to provide knowledges that related with intake of nutrients for the coaches and athletes, increasing physical activity for athletes who have low physical activity, and can be the nutritional status as a selection soccer athletes. However, further research can be done is to measure the physical endurance athletes associated with the intake of nutrients or physical activity.

    2016-12-01

    In Canada, an ageing population, obesity rates and high risk among certain ethnocultural populations are driving diabetes prevalence. Given the burden associated with type 2 diabetes and its link to modifiable risk factors, this study aimed to implement culturally preferred physical activities at the community level, targeting individuals at high risk for type 2 diabetes. Glycated hemoglobin (A1C) levels were used to detect potential improvements in glycemic control. Participants were screened for diabetes risk using a questionnaire and capillary point-of-care A1C blood testing. Participants were offered community-based physical activity classes 2 to 3 times per week for 6 months. A subset of participants (n=84) provided additional measurements. In total, 718 subjects were reached during recruitment. Substantial participant dropout took place, and 487 participants were exposed to the intervention. Among those who participated in the physical activity and provided follow up, mean A1C levels were reduced by 0.17 (p=0.002) after 3 months (n=84) and by 0.06 (p=0.35; n=49) after 6 months. The homeostatic model assessment (HOMA-beta) showed a significant improvement of 23.6% after 3 months (n=20; p=0.03) and 45.2% after 6 months (n=12; p=0.02). Resting systolic blood pressure and diastolic blood pressure plus combined hand-grip strength improved after 6 months (n=12). Implementation of this community-based, culturally preferred physical activity program presented several challenges and was associated with significant participant dropout. After considering participant dropout, the relatively small group who participated and provided follow-up measures showed improvements various physiologic measures. Despite efforts to enhance accessibility, it appears that several barriers to physical activity participation remain and need to be explored to enhance the success of future programs.

    Full Text Available This study aimed to test the reliability and validity of a Norwegian measure of adolescents’ intentions to be physically active after graduation (the Intention to be Physically Active After Graduation [IPAG] Questionnaire. The development of IPAG involved a translation and back-translation procedure and a test–retest study, performed on 105 adolescents (M age = 17.1, SD = 0.6 from three different high schools in Kristiansand, Norway. The four IPAG items loaded on one single factor, demonstrating acceptable factor loadings (.68-.90 and acceptable Cronbach’s alpha values (.84 and .84 in both the test and retest assessment. IPAG correlated positively with a measure of attitudes toward physical activity (.61-.71 and a measure of participants’ intentions to be physically active next month (.77-.82, supporting both construct validity and criterion-related validity of the IPAG-Questionnaire. Acceptable reliability and validity of IPAG was found, which supports the use of this instrument in future research.

  8. Physical activity prevents alterations in mitochondrial ultrastructure and glucometabolic parameters in a high-sugar diet model.

    Directory of Open Access Journals (Sweden)

    Karina Barbosa de Queiroz

    Full Text Available Endurance exercise is a remarkable intervention for the treatment of many diseases. Mitochondrial changes on skeletal muscle are likely important for many of the benefits provided by exercise. In this study, we aimed to evaluate the effects that a regular physical activity (swimming without workload has on mitochondrial morphological alterations and glucometabolic parameters induced by a high-sugar diet (HSD. Weaned male Wistar rats fed with a standard diet or a HSD (68% carbohydrate were subjected to 60 minutes of regular physical activity by swimming (without workload for four- (20 sessions or eight-week (40 sessions periods. After training, animals were euthanized and the sera, adipose tissues, and skeletal muscles were collected for further analysis. The HSD increased body weight after an 8-week period; it also increased the fat pads and the adipose index, resulting in glucose intolerance and insulin resistance (IR. Transmission electron microscopy showed an increase in alterations of mitochondrial ultrastructure in the gastrocnemius muscle, as well as a decrease in superoxide dismutase (SOD activity, and an increase in protein carbonylation. Regular physical activity partially reverted these alterations in rats fed a HSD, preventing mitochondrial morphological alterations and IR. Moreover, we observed a decrease in Pgc1α expression (qPCR analysis in STD-EXE group and a less pronounced reduction in HSD-EXE group after an 8-week period. Thus, regular physical activity (swimming without workload in rats fed a HSD can prevent mitochondrial dysfunction and IR, highlighting the crucial role for physical activity on metabolic homeostasis.

    The capability to produce high field strengths, and thereby obtain a new means for doing fundamental physics, has over the last thirty years taken great leaps forward. Both superconducting cavities as well ultra-intense lasers can now reach field strengths of the order 50 MV/m (stationary) and 1012 V/m (peak value, time-dependent field), respectively. Here we will describe a collection of problems that catches the flavor of the nonlinear quantum vacuum and the possibility to use high field strengths as a low-energy probe of fundamental physics.

    2015-01-01

    The purpose of this study was to analyse the longitudinal associations between (1) fundamental movement skills (FMSs) and academic performance, and (2) self-reported physical activity and academic performance through junior high school in Finland. The participants of the study were 325 Finnish students (162 girls and 163 boys), who were 13 years old at the beginning of the study at Grade 7. Students performed three FMS tests and responded to a self-reported physical activity questionnaire at Grades 7 and 8. Marks in Finnish language, mathematics and history from Grades 7, 8 and 9 were collected. Structural equation modelling with multigroup method demonstrated that in the boys' group, a correlation (0.17) appeared between FMS and academic performance measured at Grade 7. The results also indicated that FMS collected at Grade 8 were significantly but weakly (path coefficient 0.14) associated with academic performance at Grade 9 for both gender groups. Finally, the results of this study demonstrated that self-reported physical activity was not significantly related to academic performance during junior high school. The findings of this study suggest that mastery of FMS may contribute to better student achievement during junior high school.

    While the internet is considered a promising avenue for providing physical activity support to prostate cancer survivors, little is known about the accessibility of quality websites in the real world. This work aimed to explore what websites prostate cancer survivors are likely to find when seeking physical activity support online and to evaluate their quality using evidenced-based criteria. A search strategy was developed in consultation with prostate cancer survivors (n = 44) to reflect the most common ways they are likely to search the internet. The search was then conducted by a single reviewer, and identified websites were assessed for quality by two reviewers using an evidence-based quality assessment tool developed for this study. Discrepancies were resolved by a third reviewer. Of the 45 identified websites, 13 (29%) received a high quality rating, 22 (49%) received a moderate rating and 10 (22%) received a low quality rating. Higher-quality websites tended to have a .org or .gov domain and tended to be located using searches specific to prostate cancer or prostate cancer and exercise. Very few websites contained complete information regarding the physical activity guidelines for cancer survivors, and no websites provided comprehensive behaviour change support. There are some good-quality physical activity websites accessible to men with prostate cancer. However, they may be difficult to find and/or require updating to include complete recommendations and more behaviour change support. Efforts to improve physical activity information online and strategies to direct prostate cancer survivors to higher-quality websites and support services are needed to ensure safety and efficacy.

    Full Text Available Inactivity or insufficient physical activity is risk factor for metabolic or cardiovascular diseases. In most of cases the nature of work of office employees does not require high physical efforts and consists mostly of sitting but the reports on leisure activity of office workers are still lacking. Thus, the aim of the study was to assess physical activity of civil and local administration workers and bank officials. 293 randomly selected office workers took part in the study. They were recruited from employees of local (n=97 or civil (n=119 administration authorities or banks (n=77 and subjected to interviews with the use of IPAQ questionnaire (short version. Low physical activity was noted in about 70% of local administration employees, in almost 50% of bank officials and about 35% of workers employed in civil administration. Total daily time spent on sitting was on average 9.7±1.7 hour/day irrespectively of gender or group studied. Very low level of physical activity of Polish office workers may be a result of improper habits of spending spare time, low awareness of beneficial effects of physical activity and still insufficient promotion of healthy/active lifestyle in East-European countries.

    2016-11-01

    To evaluate the attrition rate of members of a fitness center in the city of Rio de Janeiro and the potential explanatory variables for the phenomenon. An exploratory, observational study using a retrospective longitudinal frame. The records of 5240 individuals, members of the fitness center between January-2005 and June-2014, were monitored for 12 months or until cancellation of membership, whichever occurred first. A Cox proportional hazard regression model was adjusted to identify variables associated to higher risk of 'abandonment' of activities. This study was approved by Southern Cross University's Human Research Ethics Committee (approval number: ECN-15-176). The general survival curve shows that 63% of new members will abandon activities before the third month, and less than 4% will remain for more than 12 months of continuous activity. The regression model showed that age, previous level of physical activity, initial body mass index and motivations related to weight loss, hypertrophy, health, and aesthetics are related to risk of abandonment. Combined, those variables represent an important difference in the probability to abandon the gym between individuals with the best and worse combination of variables. Even individuals presenting the best combination of variables still present a high risk of abandonment before completion of 12 months of fitness center membership. Findings can assist in the identification of high risk individuals and therefore help in the development of strategies to prevent abandonment of physical activity practice.

On experiment UA1 their effort will concentrate on data analysis at Riverside. At Fermilab they will coordinate the high voltage system for all detector elements. They will also carry out hardware/software development for the D0 muon detector. The TPC/Two-Gamma experiment has completed its present phase of data-taking after accumulating 160 pb{sup {minus}}1 of luminosity. The UC Riverside group will continue data and physics analysis and make minor hardware improvement for the high luminosity run. The UC Riverside group is participating in design and implementation of the data acquisition system for the OPAL experiment at LEP. Mechanical and electronics construction of the OPAL hadron calorimeter strip readout system is proceeding on schedule. Data analysis and Monte Carlo detector simulation efforts are proceeding in preparation for the first physics run when IEP operation comenses in fall 1989.

    OBJECTIVE High occupational physical activity (OPA) increases cardiovascular risk and aerobic exercise has been recommended for reducing this risk. This paper investigates the effects of an aerobic exercise intervention on 24-hour ambulatory blood pressure (ABP) among cleaners with high OPA....... METHODS Hundred and sixteen cleaners between 18 and 65 years were randomized. During the 4-month intervention period, the aerobic exercise group (AE) (n = 57) performed worksite aerobic exercise (2 × 30 minutes/week), while the reference group (REF) (n = 59) attended lectures.

    Total weight loss induced by energy restriction is highly variable even under tightly controlled conditions. Identifying weight-loss discriminants would provide a valuable weight management tool and insights into body weight regulation. This study characterized responsiveness to energy restriction in adults from variables including the plasma metabolome, endocrine and inflammatory markers, clinical indices, body composition, diet, and physical activity. Data were derived from a controlled feeding trial investigating the effect of 3-4 dairy product servings in an energy-restricted diet (2092 kJ/d reduction) over 12 wk. Partial least squares regression was used to identify weight-loss discriminants in 67 overweight and obese adults. Linear mixed models were developed to identify discriminant variable differences in high- vs. low-weight-loss responders. Both pre- and postintervention variables (n = 127) were identified as weight-loss discriminants (root mean squared error of prediction = 1.85 kg; Q(2) = 0.43). Compared with low-responders (LR), high-responders (HR) had greater decreases in body weight (LR: 2.7 ± 1.6 kg; HR: 9.4 ± 1.8 kg, P physical activity (LR: 127 ± 52 min; HR: 167 ± 68 min, P = 0.02), sedentary activity (LR: 1090 ± 99 min; HR: 1017 ± 110 min, P = 0.02), and plasma stearate [LR: 102,000 ± 21,000 quantifier ion peak height (QIPH); HR: 116,000 ± 24,000 QIPH, P = 0.01]. Overweight and obese individuals highly responsive to energy restriction had accelerated reductions in adiposity, likely supported in part by higher lipid mobilization and combustion. A novel observation was that person-to-person differences in habitual physical activity and magnitude of weight loss were accompanied by unique blood metabolite signatures.

    Aging is a multifactorial irreversible process associated with significant decline in muscle mass and neuromuscular functions. One of the most efficient methods to counteract age-related changes in muscle mass and function is physical exercise. An alternative effective intervention to improve muscle structure and performance is electrical stimulation. In the present work we present the positive effects of physical activity in elderly and a study where the effects of a 8-week period of functional electrical stimulation and strength training with proprioceptive stimulation in elderly are compared.

    The High Energy Physics group at Florida State University (FSU), which was established in 1958, is engaged in the study of the fundamental constituents of matter and the laws by which they interact. The group comprises theoretical and experimental physicists, who sometimes collaborate on projects of mutual interest. The report highlights the main recent achievements of the group. Significant, recent, achievements of the group’s theoretical physicists include progress in making precise predictions in the theory of the Higgs boson and its associated processes, and in the theoretical understanding of mathematical quantities called parton distribution functions that are related to the structure of composite particles such as the proton. These functions are needed to compare data from particle collisions, such as the proton-proton collisions at the CERN Large Hadron Collider (LHC), with theoretical predictions. The report also describes the progress in providing analogous functions for heavy nuclei, which find application in neutrino physics. The report highlights progress in understanding quantum field theory on a lattice of points in space and time (an area of study called lattice field theory), the progress in constructing several theories of potential new physics that can be tested at the LHC, and interesting new ideas in the theory of the inflationary expansion of the very early universe. The focus of the experimental physicists is the Compact Muon Solenoid (CMS) experiment at CERN. The report, however, also includes results from the D0 experiment at Fermilab to which the group made numerous contributions over a period of many years. The experimental group is particularly interested in looking for new physics at the LHC that may provide the necessary insight to extend the standard model (SM) of particle physics. Indeed, the search for new physics is the primary task of contemporary particle physics, one motivated by the need to explain certain facts, such as the

    The present study examined whether daily physical activity moderated the within-person relationship between daily fatigue and positive or negative mood in patients with rheumatoid arthritis (RA) or osteoarthritis (OA). Participants were 142 patients, 70 with RA and 72 with OA (67.6% women). Participants completed daily diaries during 4 fixed time windows per day for 7 days. Each diary assessed fatigue, pain, and positive and negative mood. Participants wore pedometers throughout each day and recorded pedometer readings at the end of each day. Physical activity buffered the same-day relationship between daily fatigue and positive mood for both RA and OA participants. On high-fatigue days, large decrements in mood were noted, but this was mitigated on days when participants were more physically active. Being more physically active on high-fatigue days buffered the negative effect of fatigue on positive mood among adults with both OA and RA. These findings have implications for understanding the daily variations in fatigue and inform potential clinical interventions. © 2015, American College of Rheumatology.

    The pathways by which physical activity impacts on participants' health are still not fully understood. The purpose of the present study was to go beyond existing research by combining methods from survey-based and experimental stress research, and by examining whether the potential of vigorous physical activity (VPA) to attenuate physiological and psychological stress responses is moderated by participants' subjective stress perception. The sample consisted of 42 undergraduate students (M=21.2±2.2 years, 52% women). Participants self-reported their stress and wore an accelerometer device for seven consecutive days. To examine differences in the adrenocortical, autonomic and psychological stress reactivity, salivary free cortisol, heart rate, state anxiety, mood and calmness were assessed prior to, during and after the Trier Social Stress Test (TSST). The cut-offs of the American College of Sports Medicine (ACSM) were used to distinguish between students below/above current VPA recommendations. High levels of perceived stress combined with VPA levels below the ACSM's standards (students with high stress/low VPA experienced less favourable affect throughout the entire testing session (pstudents with high stress levels. Our findings highlight that promoting VPA in young adults seems to be a promising strategy to increase physiological and psychological stress resilience. Copyright © 2017 Elsevier Ltd.

    Humans and rodents show large variability in their individual sensitivity to diet-induced obesity (DIO), which has been associated with differences in intrinsic spontaneous physical activity (SPA). Evidence from genetic and out-bred rat obesity models shows that higher activity of the orexin peptides results in higher intrinsic SPA and protection against DIO. Based on this, we hypothesized that naturally occurring variation in SPA and orexin signaling is sufficient to drive differences in sensitivity to DIO. Orexin expression, behavioral responses to orexin-A, basal energy expenditure and sensitivity to DIO were measured in in non-manipulated male Sprague-Dawley rats selected for high and low intrinsic SPA. Male Sprague-Dawley rats were classified as high-activity or low-activity based on differences in intrinsic SPA. High-activity rats showed higher expression of prepro-orexin mRNA, higher sensitivity to behavioral effects of orexin injection, higher basal energy expenditure and were more resistant to obesity caused by high-fat diet consumption than low-activity rats. Our results define a new model of differential DIO sensitivity, the high-activity and low-activity rats, and suggest that naturally occurring variations in intrinsic SPA cause differences in energy expenditure that are mediated by orexin signaling and alter DIO sensitivity.

    The gut microbiota is considered a relevant factor in obesity and associated metabolic diseases, for which postmenopausal women are particularly at risk. Increasing physical activity has been recognized as an efficacious approach to prevent or treat obesity, yet the impact of physical activity on the microbiota remains under-investigated. We examined the impacts of voluntary exercise on host metabolism and gut microbiota in ovariectomized (OVX) high capacity (HCR) and low capacity running (LCR) rats. HCR and LCR rats (age = 27 wk) were OVX and fed a high-fat diet (45% kcal fat) ad libitum and housed in cages equipped with (exercise, EX) or without (sedentary, SED) running wheels for 11 wk (n = 7-8/group). We hypothesized that increased physical activity would hinder weight gain, increase metabolic health and shift the microbiota of LCR rats, resulting in populations more similar to that of HCR rats. Animals were compared for characteristic metabolic parameters including body composition, lipid profile and energy expenditure; whereas cecal digesta were collected for DNA extraction. 16S rRNA gene-based amplicon Illumina MiSeq sequencing was performed, followed by analysis using QIIME 1.8.0 to assess cecal microbiota. Voluntary exercise decreased body and fat mass, and normalized fasting NEFA concentrations of LCR rats, despite only running one-third the distance of HCR rats. Exercise, however, increased food intake, weight gain and fat mass of HCR rats. Exercise clustered the gut microbial community of LCR rats, which separated them from the other groups. Assessments of specific taxa revealed significant (p<0.05) line by exercise interactions including shifts in the abundances of Firmicutes, Proteobacteria, and Cyanobacteria. Relative abundance of Christensenellaceae family was higher (p = 0.026) in HCR than LCR rats, and positively correlated (p<0.05) with food intake, body weight and running distance. These findings demonstrate that exercise differentially impacts

    Full Text Available Background: The level of physical fitness in south Asian immigrants living in Norway is largely unknown, but the level of physical activity seems to be low, possibly in part explaining their high prevalence of diabetes and cardiovascular diseases. However, previous studies have used self-reported measures of physical activity, and it might be questioned whether the previous data reflect the true physical activity level.Aim: To describe objectively measured physical activity level, cardiorespiratory fitness and diabetes risk in a group of Pakistani immigrant men living in Oslo, Norway.Methods: One hundred and fifty Pakistani immigrant men in the age group 25-60 years were included. Physical activity level was assessed with an accelerometer. Cardiorespiratory fitness was measured until exhaustion on a treadmill, and diabetes risk was evaluated with an oral glucose tolerance test.Results: Mean age was 37.3 years (SD=7.7. Total physical activity level was 308 counts/min (SD=131, and peak oxygen uptake was 34.2 ml·kg-1·min-1 (SD=5.6. Fifty percent of the participants had the metabolic syndrome, and 76% were obese. Physical activity level and cardiorespiratory fitness level were lower, and prevalence of the metabolic syndrome higher in a subgroup of taxi drivers as compared with those inother occupations (P<0.05.Conclusions: Physical activity and cardiorespiratory fitness levels are low and diabetes risk high among Pakistani immigrant men living in Oslo, especially in taxi drivers

    To evaluate in a rat animal model whether ovariectomy, high fat diet (HFD), and physical activity in the form of running affect leptin receptor (Ob-R) distribution in the brain and white fat tissue compared to sham (Sh) surgery, standard diet (StD), and sedentary conditions. The study included 48 female laboratory Wistar rats (4 weeks old). Following eight weeks of feeding with standard or HFD, rats were subjected to either OVX or Sh surgery. After surgery, all animals continued StD or HFD for the next 10 weeks. During these 10 weeks, ovariectomy and Sh groups were subjected to physical activity or sedentary conditions. Free-floating immunohistochemistry and Western blot methods were carried out to detect Ob-R in the brain and adipose tissue. StD-ovariectomy-sedentary group had a greater number of Ob-R positive neurons in lateral hypothalamic nuclei than StD-Sh-sedentary group. There was no difference in Ob-R positive neurons in arcuatus nuclei between all groups. Ob-R distribution in the barrel cortex was higher in HFD group than in StD group. Ob-R presence in perirenal and subcutaneous fat was decreased in StD-ovariectomy group. HFD and ovariectomy increased Ob-R distribution in lateral hypothalamic nuclei, but there was no effect on arcuatus nuclei. Our results are first to suggest that HFD, ovariectomy, and physical activity affect Ob-R distribution in the barrel cortex, which might be correlated with the role of Ob-R in election of food in rats.

  1. An After-School, high-intensity, interval physical activity programme improves health-related fitness in children

    Directory of Open Access Journals (Sweden)

    Sergio Reloba Martínez

    Full Text Available Abstract Health problems related to a low level of physical activity (PA in children and adolescents have prompted research into extracurricular PA programs. This study was designed to determine the effects of two different levels of PA on the health-related fitness of school children. Ninety-four girls and boys (7-9 years were randomly assigned to a control group (CG or intervention group (IG. Over a 12 week study period, children in the CG participated in a similar PA program to that of a standard school physical education program while those in the IG completed a high intensity interval training (HIIT program. Both programs involved two 40 minute extracurricular sessions per week. Our findings indicate that the HIIT intervention improved motor capacity (speed/agility, Vpeak, VO2 max and excess post-exercise oxygen consumption (EPOC (p < 0.05 along with the musculoskeletal capacity of the lower trunk (mean propulsive velocity and standing long jump, p < 0.05. The PA program had no effect on anthropometric variables or hand-grip strength. The data indicate that a 12 week strength training program using workloads adapted to children may significantly improve several markers of health and physical fitness compared to a standard school PA program.

    This proposal is for the continuation of the High Energy Physics Program at the University of California, Riverside. In 1990, we will concentrate on analysis of LEP data from the OPAL detector. We expect to record 10{sup 5} Z`s by the end of 1989 and 10{sup 6} in 1990. This data will be used to measure the number of quark-lepton families in the universe. In the second half of 1990 we will also be occupied with the installation of the D-Zero detector in the Tevatron Collider and the preparation of software for the 1991 run. A new initiative made possible by generous university support is a laboratory for detector development at UCR. The focus will be on silicon strip tracking detectors both for the D-Zero upgrade and for SSC physics. The theory program will pursue further various mass-generating radiative mechanisms for understanding small quark and lepton masses as well as some novel phenomenological aspects of supersymmetry.

    Drinking plain water instead of sugar-sweetened beverages is one approach for reducing energy intake. Only a few studies have examined characteristics associated with plain water intake among US youth. The purpose of our cross-sectional study was to examine associations of demographic characteristics, weight status, dietary habits, and other behavior-related factors with plain water intake among a nationally representative sample of US high school students. The 2010 National Youth Physical Activity and Nutrition Study data for 11,049 students in grades 9 through 12 were used. Multivariable logistic regression analysis was used to calculate adjusted odds ratios (ORs) and 95% CIs for variables associated with low water intake (water water intake were age ≤15 years (OR 1.1), consuming milk (OR 1.5), nondiet soda ≥1 time/day (OR 1.6), other sugar-sweetened beverages ≥1 time/day (OR 1.4), fruits and 100% fruit juice active ≥60 minutes/day on water intake (OR 0.7). The findings of these significant associations of low water intake with poor diet quality, frequent fast-food restaurant use, and physical inactivity may be used to tailor intervention efforts to increase plain water intake as a substitute for sugar-sweetened beverages and to promote healthy lifestyles.

    Physical activity has been shown in large cohort studies to positively impact survival in cancer survivors. Existing randomized controlled trials showed a beneficial effect of physical activity on physical fitness, quality of life, anxiety and self-esteem; however, the small sample size, the short follow-up and the lack of standardization of physical activity intervention across studies impaired definite conclusion in terms of survival. Physical activity reduces adiposity and circulating estrogen levels and increases insulin sensitivity among other effects. A workshop was conducted at the International Agency for Research on Cancer in April 2011 to discuss the role of physical activity on cancer survival and the methodology to develop multicentre randomized intervention trials, including the type of physical activity to implement and its association with nutritional recommendations. The authors discuss the beneficial effect of physical activity on cancer survival with a main focus on breast cancer and report the conclusions from this workshop.

    High occupational physical activity (OPA) increases cardiovascular risk and aerobic exercise has been recommended for reducing this risk. This paper investigates the effects of an aerobic exercise intervention on 24-hour ambulatory blood pressure (ABP) among cleaners with high OPA. Hundred and sixteen cleaners between 18 and 65 years were randomized. During the 4-month intervention period, the aerobic exercise group (AE) (n = 57) performed worksite aerobic exercise (2 × 30 minutes/week), while the reference group (REF) (n = 59) attended lectures. Between-group differences in 4-month ABP changes were evaluated by intention-to-treat analysis using a repeated-measure 2 × 2 multiadjusted mixed-models design. Relative to REF, 24-hour ABP significantly increased in AE: systolic 3.6 mm Hg (95% confidence interval (CI) 1.6-5.7) and diastolic 2.3 mm Hg (95% CI 0.9-3.8). Cleaners with high aerobic workload exhibited particularly high 24-hour ABP increases: systolic 6.0 mm Hg (95% CI 2.4-9.6), and diastolic 3.8 mm Hg (95% CI 1.3-6.4). Aerobic exercise increased 24-hour ABP among cleaners. This adverse effect raises questions about the safety and intended benefits of aerobic exercise, especially among workers with high OPA and a demanding aerobic workload. http://www.controlled-trials.com/ISRCTN86682076.

    Full Text Available Physical activity is the most beneficial intervention in prevention and treatment of chronic diseases. Life style, which has become mostly sedentary, leads to growing incidence in obesity, what could cause the first so far reduction in life expectancy in developed countries.Physical activity reduces the chronic low-grade inflammation, which plays an important role in the pathogenesis of type 2 diabetes, cardiovascular disease and certain types of cancer. Regular physical activity exerts two anti-inflammatory effects: reduction of visceral fat, which produces the majority of pro-inflammatory cytokines, and production of myokines. It has been proposed that cytokines and other peptides that are produced by muscle fibers should be classified as myokines that exert autocrine, paracrine and endocrine effects. Myokines induce muscle hypertrophy and myogenesis, stimulate fat oxidation, improve insulin sensitivity and have an anti-inflammatory effect.  Therefore, skeletal muscle has been identified as a secretory organ and this provides the basis for understanding how muscles communicate with other organs, such as adipose tissue, liver, pancreas, gut, bones and brain. Physical inactivity leads to an altered myokine profile, associating sedentary life style with some chronic diseases.Physical activity is recommended as a tool for weight management and prevention of weight gain, for weight loss and for prevention of weight regain. High quality studies have confirmed the important impact of exercise on improving blood glucose control in diabetic patients, and on preventing or delaying the onset of type 2 diabetes in predisposed populations. Prescribing specific exercise tailored to individual's needs is an intervention strategy for health improvement. Physical fitness counteracts the detrimental effects of obesity reducing morbidity and mortality.

    Mental health is one of the evaluating factors of community indicators, and physical activity is considered an important tool for the importance of public health. Previous studies have demonstrated associations between physical activity and mental health, but these studies did not include those populations in which training children have some traditional and religious aspects. Multiple logistic regression analyses were used to compare the prevalence of mental health among those who had inactive, minimally and HEPA activity in a representative sample of adolescents aged 15-19 in South of Iran using data from the Mental Health Survey (n=2584). The GHQ-28 and IPAQ-short forms were used to evaluate the mental health and physical activity, respectively. A total of 2584 adolescents (1401 male and 1178 female) participated in the study. The observed odds of psychological symptoms in boys compared to girls is 1.2 times (p=0.018). We observed that HEPA-activity decreases odds of somatic distress and social dysfunction compared with inactivity (p=0.031 and 0.001, respectively); minimally activity decreases odds of anxiety compared with inactivity (p=0.038); but physical activity rate was not affected on odds of adolescent's depression (p>0.05). Physical activity decreases mental health subscales except for depression among adolescents in Boushehr, southern city of Iran.

    Full Text Available The gut microbiota is considered a relevant factor in obesity and associated metabolic diseases, for which postmenopausal women are particularly at risk. Increasing physical activity has been recognized as an efficacious approach to prevent or treat obesity, yet the impact of physical activity on the microbiota remains under-investigated. We examined the impacts of voluntary exercise on host metabolism and gut microbiota in ovariectomized (OVX high capacity (HCR and low capacity running (LCR rats. HCR and LCR rats (age = 27 wk were OVX and fed a high-fat diet (45% kcal fat ad libitum and housed in cages equipped with (exercise, EX or without (sedentary, SED running wheels for 11 wk (n = 7-8/group. We hypothesized that increased physical activity would hinder weight gain, increase metabolic health and shift the microbiota of LCR rats, resulting in populations more similar to that of HCR rats. Animals were compared for characteristic metabolic parameters including body composition, lipid profile and energy expenditure; whereas cecal digesta were collected for DNA extraction. 16S rRNA gene-based amplicon Illumina MiSeq sequencing was performed, followed by analysis using QIIME 1.8.0 to assess cecal microbiota. Voluntary exercise decreased body and fat mass, and normalized fasting NEFA concentrations of LCR rats, despite only running one-third the distance of HCR rats. Exercise, however, increased food intake, weight gain and fat mass of HCR rats. Exercise clustered the gut microbial community of LCR rats, which separated them from the other groups. Assessments of specific taxa revealed significant (p<0.05 line by exercise interactions including shifts in the abundances of Firmicutes, Proteobacteria, and Cyanobacteria. Relative abundance of Christensenellaceae family was higher (p = 0.026 in HCR than LCR rats, and positively correlated (p<0.05 with food intake, body weight and running distance. These findings demonstrate that exercise differentially

    Full Text Available In this work we investigated particular reasons that take medium physics teachers to use or not experimental activities. Starting from the presupposition that experimental activities in physics are important for teaching, it is essentially looked for to understand the reasons of the “experimental failure”, in the sense of little given importance to that teaching practice, demonstrable by absence of practically widespread of empiric activities in physics schools. We associated the relationship professional knowledge physics teacher's with that little instructional practice. Based in a reading of the ideas of Charlot, we directed an argument line that seeks to reinterpret the inadequacy of the explanation found in the lack or absence of something that is commonly disseminated in the literature in scientific education.

    Studies exploring the association between physical activity, screen time and sleep and pain usually focus on a limited number of painful body sites. Nevertheless, pain at different body sites is likely to be of different nature. Therefore, this study aims to explore and compare the association between time spent in self-reported physical activity, in screen based activities and sleeping and i) pain presence in the last 7-days for 9 different body sites; ii) pain intensity at 9 different body sites and iii) global disability. Nine hundred sixty nine students completed a questionnaire on pain, time spent in moderate and vigorous physical activity, screen based time watching TV/DVD, playing, using mobile phones and computers and sleeping hours. Univariate and multivariate associations between pain presence, pain intensity and disability and physical activity, screen based time and sleeping hours were investigated. Pain presence: sleeping remained in the multivariable model for the neck, mid back, wrists, knees and ankles/feet (OR 1.17 to 2.11); moderate physical activity remained in the multivariate model for the neck, shoulders, wrists, hips and ankles/feet (OR 1.06 to 1.08); vigorous physical activity remained in the multivariate model for mid back, knees and ankles/feet (OR 1.05 to 1.09) and screen time remained in the multivariate model for the low back (OR = 2.34. Pain intensity: screen time and moderate physical activity remained in the multivariable model for pain intensity at the neck, mid back, low back, shoulder, knees and ankles/feet (Rp(2) 0.02 to 0.04) and at the wrists (Rp(2) = 0.04), respectively. Disability showed no association with sleeping, screen time or physical activity. This study suggests both similarities and differences in the patterns of association between time spent in physical activity, sleeping and in screen based activities and pain presence at 8 different body sites. In addition, they also suggest that the factors associated

    This final report summarizes activities of the Florida Tech High Energy Physics group supported by DOE under grant #DE-SC0008024 during the period June 2012 – March 2015. We focused on one of the main HEP research thrusts at the Energy Frontier by participating in the CMS experiment. We were exploiting the tremendous physics opportunities at the Large Hadron Collider (LHC) and prepared for physics at its planned extension, the High-Luminosity LHC. The effort comprised a physics component with analysis of data from the first LHC run and contributions to the CMS Phase-2 upgrades in the muon endcap system (EMU) for the High-Luminosity LHC. The emphasis of our hardware work was the development of large-area Gas Electron Multipliers (GEMs) for the CMS forward muon upgrade. We built a production and testing site for such detectors at Florida Tech to complement future chamber production at CERN. The first full-scale CMS GE1/1 chamber prototype ever built outside of CERN was constructed at Florida Tech in summer 2013. We conducted two beam tests with GEM prototype chambers at CERN in 2012 and at FNAL in 2013 and reported the results at conferences and in publications. Principal Investigator Hohlmann served as chair of the collaboration board of the CMS GEM collaboration and as co-coordinator of the GEM detector working group. He edited and authored sections of the detector chapter of the Technical Design Report (TDR) for the GEM muon upgrade, which was approved by the LHCC and the CERN Research Board in 2015. During the course of the TDR approval process, the GEM project was also established as an official subsystem of the muon system by the CMS muon institution board. On the physics side, graduate student Kalakhety performed a Z' search in the dimuon channel with the 2011 and 2012 CMS datasets that utilized 20.6 fb⁻¹ of p-p collisions at √s = 8 TeV. For the dimuon channel alone, the 95% CL lower limits obtained on the mass of a Z' resonance are 2770 Ge

    This Progress Report presents a review of the research done in 1992 by the Duke High Energy Physics Group. This is the first year of a three-year grant which was approved by the Office of High Energy Physics at DOE after an external review of our research program during the summer of 1991. Our research is centered at Fermilab where we are involved with two active experiments, one using the Tevatron collider (CDF, the Collider Detector Facility) and the other using a proton beam in the high intensity laboratory (E771, study of beauty production). In addition to these running experiments we are continuing the analysis of data from experiments E735 (collider search for a quark-gluon plasma), E705 (fixed target study of direct photon and {sub {Chi}} meson production) and E597 (particle production from hadron-nucleus collisions). Finally, this year has seen an expansion of our involvement with the design of the central tracking detector for the Solenoidal Detector Collaboration (SDC) and an increased role in the governance of the collaboration. Descriptions of these research activities are presented in this report.

    Full Text Available Introduction: The dynamic development of the automotive industry, transport, and the media means that human life has become much easier. At the same time, the comfortable living conditions have decreased physical activity. Biologically conditioned, the need of activity has been minimised by the ever-increasing pace of life. As a result, it may lead to the loss of physical and mental health. Active recreation is not only an excellent source of activity, but also a source of satisfaction. Youths and adults should therefore spend their free time primarily on various forms of physical activity. Aim of the research : To evaluate the physical fitness of students who regularly practice physical exercise, those who occasionally practice, and those not practicing any form of physical activity. Material and methods : In the research we used a questionnaire of the Ruffier test and an orthostatic test. The study involved a group of 15 people aged 20–25 years. Participation in the study was entirely voluntary and anonymous. The study group consisted only of women. Results obtained from the questionnaire survey were fully reflected during exercise tests performed. Results and conclusions: Only regularly practiced physical activity has an effect on our body. Regular exercise increases our body’s physical capacity. Activity is the best means of prevention of lifestyle diseases. Youths and adults should spend their free time mainly doing various forms of physical activity.

    In our September column, we noted that Hispanic and African-American seniors were less likely to have taken a high school physics course than their peers, and we suggested that socioeconomic status (SES) played a role in the lower participation. In the figure, we display the proportion of seniors, of physics teachers, and of physics enrollments at schools by SES. While the number of seniors is roughly one-third in each group, physics enrollments differ dramatically by SES. Furthermore, the disparity in enrollments is greater than the disparity in physics teachers; this means that the teachers teaching physics at "better off" schools teach more physics than the physics teachers at "worse off" schools. Thus, a physics teacher at a "better off" school is more likely to teach a majority of their classes in physics.

    Erectile dysfunction (ED) is especially common in men with cardiovascular diseases (CVDs). However, the data are scarce concerning populations without manifested CVD. The aim of this study was to describe factors associated with ED, especially those associated with decreasing risk of ED, in men with cardiovascular risk factors but without CVD, diabetes, or chronic renal disease. In 2004 to 2007, a cross-sectional population-based sample of men 45 to 70 years old in two rural towns in Finland was collected. Men with previously diagnosed CVD, diabetes, or kidney disease were not invited to the study. In total 1,000 eligible men with cardiovascular risk factors, i.e., central obesity, high scores in the Finnish Diabetes Risk Score, high blood pressure, antihypertensive medication, or family history of coronary heart disease, myocardial infarction, or stroke, were included in the analysis. Questionnaires, clinical measurements, and laboratory tests were obtained. The prevalence of ED was studied comparing the means, and risk factors were studied using multivariate logistic regression analysis. The rate of ED was defined by the International Index of Erectile Function short form (IIEF-5) and by two questions (2Q) about the ability to achieve and to maintain an erection. The prevalence of ED was 57% or 68% using IIEF-5 or 2Q, respectively. Age (odds ratio [OR]: up to 9.16; 95% confidence interval [CI], 5.00-16.79; P physical activity (OR: 0.50; 95% CI, 0.29-0.86; P = 0.045), high education (OR: 0.52; 95% CI, 0.33-0.83; P = 0.013), and stable relationship (OR: 0.43; 95% CI, 0.21-0.88; P = 0.046) were associated with ED. In apparently healthy men with cardiovascular risk factors, decreasing risk of ED is associated with high-intensity physical activity, stable relationship, and high education level. © 2014 International Society for Sexual Medicine.

    To investigate whether influence at work modifies the association between demanding and strenuous occupational physical activity (OPA) and risk of ischaemic heart disease (IHD). A sample of 12,093 nurses aged 45-64 years from the Danish Nurse Cohort Study was followed for 20.6 years by individual linkage to incident IHD in the Danish National Patient Registry. Information on OPA, influence at work, other occupational factors and known risk factors for IHD was collected by self-report in 1993. During follow-up 869 nurses were hospitalised with incident IHD. Nurses exposed to strenuous OPA and low influence at work had a 46% increased risk of IHD [hazard ratio (HR) 1.46 (95% confidence interval (CI) 1.02-2.09)] compared to the reference group of nurses with moderate OPA and high influence at work. Nurses exposed to strenuous OPA and high influence at work were not at an increased risk of IHD [HR 1.10 (95% CI 0.59-2.06)]. An additive hazards model showed there were 18.0 (95% CI -0.01 to 36.0) additional cases of IHD per 10,000 person years among nurses with strenuous OPA and low influence at work compared to nurses with moderate OPA and high influence at work. A detrimental additive interaction between strenuous OPA and low influence at work that could explain the additional cases of IHD among nurses with strenuous OPA and low influence at work was indicated. The findings suggest that high influence at work may buffer some of the adverse effects of strenuous OPA on risk of IHD.

    Full Text Available Physical activity levels in children have been steadily decreasing in recent years. Reduced physical activity leads to numerous chronic diseases at an early age, particularly obesity. Lifelong participation in physical activity and maintenance of ideal bodyweight are highly effective in the prevention of chronic diseases such as obesity, cardiovascular diseases, hypertension, Type II diabetes, lung and colon cancers. At the same time physical activity increases self-confidence, self-esteem and academic achievement, and reduces symptoms of depression. Therefore, this study was designed to improve awareness of professional groups and families working with children and adolescents about physical activity benefits on children health, as well as psychosocial benefits and planned to offer suggestions for increasing physical activity levels of children.

    2014-01-01

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

    Daily physical activity shows substantial inter-individual variation, and low physical activity is associated with obesity and weight gain. Elevated physical activity is also associated with high intrinsic aerobic capacity, which confers considerable metabolic health benefits. Rats artificially selected for high intrinsic aerobic capacity (high-capacity runners, HCR) are more physically active than their low-capacity counterparts (low-capacity runners, LCR). To test the hypothesis that physic...

    To characterize the effects of a calorie matched high-fat diet (HFD) on spontaneous physical activity (SPA), body weight, inflammatory status and expression of genes related to energy homeostasis in hypothalamus of mice. C57Bl/6 mice (n=5 per group) were fed a control diet (16.5% calories from fat) - control group (C), or a calorie matched HFD (60% calories from fat). We evaluated, periodically, body weight and SPA by infrared beam sensors and, at the end of the 12th week, we verified blood glucose levels, fat pads weight, plasma insulin, TNF-α and IL-6 by ELISA and the hypothalamic expression of 84 genes related to energy homeostasis, by quantitative real-time PCR array. Isocaloric HFD reduced SPA already in the first 48h and SPA was kept lower in the HFD compared to C throughout. These changes resulted in an increase in body weight, adiposity, TNF-α and IL-6, blood glucose and hyperinsulinemia in the HFD group when compared to the C group. Expression of the Agrp, Bdnf, Adra2b and Pyy genes were altered in the hypothalamus of HFD-fed mice, highlighting the downregulation of Bdnf, key regulator of energy homeostasis. Dietary macronutrient distribution plays an important part in energy homeostasis that goes beyond its energy content. Despite calorie-matched, the HFD led to increased body weight and adiposity due to decreased SPA, highlighting the key role of SPA on energy balance. The changes in hypothalamic gene expression seem to underlie the reduction in SPA caused by HFD. Copyright © 2017 Elsevier Inc. All rights reserved.

  17. Physical activity and brain development.

    2015-01-01

    Brain development is a complex process, and stimuli during this developmental period may modulate the brain's functional maturation and determine its lifelong integrity. Human and animal studies have shown that environmental stimuli such as physical activity habits seem to have a favorable influence on brain development. Research on humans has demonstrated improvement in cognitive performance in the children of women who exercised regularly throughout pregnancy and in individuals who were physically active during childhood and adolescence. Investigations using animal models have also reported that physical activity improves the cognitive function of developing rats. In this review, we will present the neurobiological mechanisms of such effects.

  3. Leisure-time physical activity in relation to occupational physical activity among women.

    Science.gov (United States)

    Ekenga, Christine C; Parks, Christine G; Wilson, Lauren E; Sandler, Dale P

    2015-05-01

    The objective of this study is to examine the association between occupational physical activity and leisure-time physical activity among US women in the Sister Study. We conducted a cross-sectional study of 26,334 women who had been employed in their current job for at least 1 year at baseline (2004-2009). Occupational physical activity was self-reported and leisure-time physical activity was estimated in metabolic equivalent hours per week. Log multinomial regression was used to evaluate associations between occupational (sitting, standing, manually active) and leisure-time (insufficient, moderate, high) activity. Models were adjusted for age, race/ethnicity, education, income, geographic region, and body mass index. Only 54% of women met or exceeded minimum recommended levels of leisure-time physical activity (moderate 32% and high 22%). Women who reported sitting (prevalence ratio (PR)=0.82, 95% confidence interval (CI): 0.74-0.92) or standing (PR=0.84, 95% CI: 0.75-0.94) most of the time at work were less likely to meet the requirements for high leisure-time physical activity than manually active workers. Associations were strongest among women living in the Northeast and the South. In this nationwide study, low occupational activity was associated with lower leisure-time physical activity. Women who are not active in the workplace may benefit from strategies to promote leisure-time physical activity. Published by Elsevier Inc.

    Full Text Available The aim of this paper was to examine the amount and type of physical activity engaged in by people hospitalised after stroke. Method. We systematically reviewed the literature for observational studies describing the physical activity of stroke patients. Results. Behavioural mapping, video recording and therapist report are used to monitor activity levels in hospitalised stroke patients in the 24 included studies. Most of the patient day is spent inactive (median 48.1%, IQR 39.6%–69.3%, alone (median 53.7%, IQR 44.2%–60.6% and in their bedroom (median 56.5%, IQR 45.2%–72.5%. Approximately one hour per day is spent in physiotherapy (median 63.2 minutes, IQR 36.0–79.5 and occupational therapy (median 57.0 minutes, IQR 25.1–58.5. Even in formal therapy sessions limited time is spent in moderate to high level physical activity. Low levels of physical activity appear more common in patients within 14 days post-stroke and those admitted to conventional care. Conclusions. Physical activity levels are low in hospitalised stroke patients. Improving the description and classification of post stroke physical activity would enhance our ability to pool data across observational studies. The importance of increasing activity levels and the effectiveness of interventions to increase physical activity after stroke need to be tested further.

  10. Epilepsy, physical activity and sports

    Directory of Open Access Journals (Sweden)

    Full Text Available People with epilepsy are prone to be sedentary compared with the general population. The causes of inactivity are ignorance, prejudice, overprotection, fear and shame. There is no scientific evidence supporting a limitation of physical exercise in persons with epilepsy. The benefits of exercise in these patients are huge. Positive aspects are: physical conditioning, prevention of seizures, emotional wellbeing, social interaction, drug treatment adherence, osteoporosis prevention and better quality of life for patients and their families. Having in mind the individual characteristics, physical exercise should be prescribed and guided. Available evidence underlies the complementary therapeutic effects of physical activity with large positive results at a low cost. Sports or regular physical activity should be a standard indication for persons with epilepsy.

    2009-10-01

    Physical inactivity is one of the leading causes of death, disability, and health care costs, but resources and other investments in promoting physical activity are neither proportional to nor ideally suited to address the problem, especially in the United States. Capacity for physical activity promotion is lacking, when compared to the response to other major health risk and protective behaviors. The authors of the commentaries in this special issue were asked to identify key issues from a variety of perspectives and to recommend actions that can be taken now to increase physical activity across the population so that all segments of society benefit, especially those at high risk of chronic diseases. The goal is to stimulate research institutions, public health agencies at all levels, and policy makers to raise physical activity as a priority commensurate with other pressing public health concerns.

    To investigate the association between physical activity, functional activity of high-density lipoprotein (HDL), and subclinical cardiovascular disease in patients with systemic lupus erythematosus (SLE). A total of 242 SLE patients (all women) participated in this cross-sectional study from February 2004 to February 2008. Carotid plaque and intima-media thickness (IMT), antioxidant function of HDL, and traditional cardiac risk factors were measured. Physical activity was assessed from self-reports by calculating the metabolic equivalents (METS) per week and by the physical function domain of the Medical Outcomes Study Short Form 36 (SF-36). Data were analyzed using bivariate and multivariate regression analyses. Number of METS per week spent performing strenuous exercise was negatively correlated with IMT (r = -0.4, P = 0.002) and number of plaques (r = -0.30, P = 0.0001). Physical function as assessed by the SF-36 was also negatively correlated with IMT (r = -0.14, P = 0.03) and number of plaques (r = -0.14, P = 0.04). In multivariate analyses, number of strenuous exercise METS was significantly associated with IMT (t = -2.2, P = 0.028) and number of plaques (t = -2.5, P = 0.014) when controlling for markers of SLE disease activity and damage, but not after controlling for traditional cardiac risk factors. Low physical activity, defined as exercise may reduce the risk of atherosclerosis in SLE.

    Full Text Available ​Background and Objectives : Adolescence is a proper time to make lifestyle changes to reduce the incidence of chronic diseases in the adulthood. This study aimed to describe the anthropometric indices and physical activities status and their relationship with musculoskeletal complaints in high school female students in Tabriz. Materials and Methods : Two hundred students were selected by cluster sampling method. Anthropometric indicators, physical activity level and musculoskeletal complaints were determined using standard protocols and questionnaires. Statistical analysis of data was performed according to age and body types. Results : The mean age and BMI of the subjects were 17.12 years and 22.16 kg/m2, respectively. About 20% of the students were overweight or obese. The body type of the students was endomorph-mesomorph. Only 8% of the students exercised in gyms and 31% spent more than three hours a day watching television and 70% did the housework. Body type and Body Mass Index did not differ significantly between age groups. Logistic regression models showed no relationship between musculoskeletal complaints, physical activities and body types. Conclusion : This study showed reduction in the physical activities of female students, but there was no significant relationship between musculoskeletal complaints, physical activities and body types.

    Full Text Available Abstract Background Given the increasing importance of obesity in China, prevention interventions encouraging physical activity by middle school students are needed. The purpose of this study is to illustrate how a rapid elicitation method can be used to identify salient consequences, referents, and circumstances about physical activity as perceived by middle school students and to provide suggestions for interventions and quantitative research. Method A theory-based qualitative study using a self-completion elicitation was conducted with 155 students from two middle schools in Beijing, China. Following the Theory of Planned Behavior, six open-ended questions asked students for their perceptions about performing physical activity at least 60 minutes each day: advantages of participating in physical activity; disadvantages of doing so; people who approve of participation; people who disapprove; things that make it easy; and things that make it hard. Content analysis revealed categories of salient consequences, reference groups, and circumstances. Results While the three most frequently mentioned advantages elicited from the students were physical health consequences (e.g., will strengthen my body (58.7%, four of the salient advantages were not (e.g., will improve my grades (12.2%. Parents were the most frequently mentioned social referent (42.6% as approving; 27.7% as disapproving when students were asked who might approve or disapprove of their participation. Circumstances perceived to hinder daily physical activity included having too many assignments and not having enough time. Conclusion While many of the beliefs about physical activity elicited from this study were similar to those found with students from England and the US, several were unique to these students from Beijing. The results of this qualitative research suggest that interventions to encourage physical activity among middle school students should address: perceived consequences

    One of the major difficulties in learning physics is for students to develop a conceptual understanding of the core concepts of physics. Many authors argue that students’ conceptions of basic physical phenomena are rooted in basic schemas, originating in fundamental kinaesthetic experiences...... of being. We argue that this idea should be utilized in physics instruction, that kinaesthetic activities will provide useful entry point for students’ acquisition of the basic conceptions of physics, and that they can overcome the phenomenological gap between experiential and conceptual understanding. We...... discuss the nature of image schemas and focus particularly on one: effort-resistance-flow. This schema is fundamental not only in our everyday experience, but also in most of school physics. We show how enactment of a particular kinaesthetic model can support student understanding and intuition...

  19. Physical activity and obesity in children.

    Science.gov (United States)

    Hills, Andrew P; Andersen, Lars Bo; Byrne, Nuala M

    2011-09-01

    Globally, obesity is affecting an increasing proportion of children. Physical activity plays an important role in the prevention of becoming overweight and obese in childhood and adolescence, and reducing the risk of obesity in adulthood. Puberty and the following adolescent period are acknowledged as particularly vulnerable times for the development of obesity due to sexual maturation and, in many individuals, a concomitant reduction in physical activity. In many Western settings, a large proportion of children and adolescents do not meet recommended physical activity guidelines and, typically, those who are more physically active have lower levels of body fat than those who are less active. Active behaviours have been displaced by more sedentary pursuits which have contributed to reductions in physical activity energy expenditure. Without appropriate activity engagement there is an increased likelihood that children will live less healthy lives than their parents. Owing to the high risk of overweight adolescents becoming obese adults, the engagement of children and adolescents in physical activity and sport is a fundamental goal of obesity prevention.

    To investigate the relationship between physical activity and metabolic syndrome (MS). A multi-stage stratified cluster sampling was conducted in 132 sampling 218,920 residents, aged 44.3 +/- 15.3 (15 - 96), in the 31 provinces, autonomous regions, and municipalities of the mainland China according to the program of the National Nutrition and Health Survey. Questionnaire survey, interview, physical examination, measurement of biochemical indices, and dietary investigation were done. Information of physical activity and measurement of fasting glucose and/or glucose 2 hours after meal, blood pressure, triglycerides, high-density lipoprotein cholesterol were obtained in 50,494 participants. Metabolic syndrome was defined according to the Chinese Medical Association's definition. The intensity of physical activity was divided into 3 categories according to the Center for Disease Control and Prevention of US/American College of Sports Medicine criteria. 50,495 subjects, 23,932 males (47.4%) and 26,562 females (52.6%), were diagnosed as with MS. The MS incidence of those with high intensity of physical activity was lower by 60% in comparison with those with low intensity of physical activity (odds ratio 0.60, 95% CI: 0.362 - 0.443) adjusted for age, sex, smoking, and alcohol intake. The risk of MS in those with moderate intensity of physical activity of 151 - 300 minutes/week was slightly decreased compared to those with moderate intensity of physical activity of 90 - 150 minutes/week, (odds ratio 0.935, 95% CI: 0.685 - 1.277), however, the risk of MS in those with the moderate intensity of physical activity over 300 minutes/week increased slightly (OR = 1.269, 95% CI: 0.923 - 1.745). The risk of MS in those with low-level physical activity of 301 - 420 minutes/week was lower by 35% in comparison with those with the low-level physical activity of 90 - 150 minutes/week (95% CI: 0.451 - 0.933), however, the risk of MS in those with the low-level physical activity over 420

    Full Text Available Abstract The study aimed to identify urban environmental characteristics, which may be associated with the physical activity (PA level of women from Brazilian cities of Santa Catarina. The sample was composed of 2047 women aged 20 to 59 from six Santa Catarina cities: Blumenau, Chapecó, Criciúma, Florianópolis, Itajaí, and São José. The PA was evaluated through the IPAQ (short version, and the NEWS to environmental variables. An inferential and descriptive statistic was used: Chi-squared test, ANOVA with post hoc, and raw and adjusted multinomial regression analysis (p < .05. The participants from São José presented greater chances to PA practice when they reside close to appropriated areas, sidewalks, fitness centers, well-lit streets, and when invited by relatives to the practice. The PA Program for the community enables greater chances of practice for women in Florianópolis, São José, Criciúma and Blumenau. As a conclusion, some environmental factors appeared to influence PA practice positively in Catarinense women. Besides that, the fact of belonging to the high economic status could increasingly enable practice, since they seem broader access to gyms and PA private professionals.

    2007-01-01

    To describe the physical activity profile of Saudi adults living in Riyadh, using the International Physical Activity Questionnaire (IPAQ) short-version telephone format. Physical activity was assessed using the official Arabic short form of IPAQ, intended for use in telephone interview. The instrument asks for times spent in walking, moderate- and vigorous-intensity physical activity of at least 10 min duration. The sample consisted of 1616 Saudis, between 15 and 78 years of age, living in Riyadh. Participants were drawn from a list of names in the telephone book using a simple random method. Telephone interviews were administered during the spring of 2003 by trained male interviewers. The final sample size was 1064 Saudi males and females (response rate of 66%), with males comprising about 66% of the respondents. Over 43% of Saudis did not participate in any type of moderate-intensity physical activity lasting for at least 10 min. More than 72% of the sample did not engage in any type of vigorous-intensity physical activity lasting for at least 10 min. The proportion of Saudis who walked for 150 min or more per week was 33.3%. Females were engaged more in moderate physical activity than males, whereas males participated more in vigorous activity compared with females. Activity levels did not show significant relationships with education level or job hours per week. Based on the three activity categories established by IPAQ, 40.6% of Saudis were inactive, 34.3% were minimally active and 25.1% were physically active. Physical inactivity increased with advancing age. The data suggest that the prevalence of physical inactivity among Saudis adults is relatively high. Efforts are needed to encourage Saudis to be more physically active, with the goal of increasing the proportion of Saudis engaging in health-enhancing physical activity.

    Failure to attain fat balance may contribute to obesity development even without excessive energy intake. The objective of this study was to examine the associations of dietary macronutrient distribution with abdominal adiposity in adolescents and to evaluate whether these relationships were attenuated by physical activity. A total of 224 Spanish adolescents (51% females, 14.9 ± 1.2 years) were included in the study. Abdominal adiposity in three regions, truncal and total body fat mass (FM) and lean mass (LM) were measured by dual-energy X-ray absorptiometry and thereafter FM index (FMI = FM/height(2)) and FMI/LMI ratio were calculated. The energy derived from fat intake was assessed by two non-consecutive 24 h recalls. Total physical activity (PA) and time spent in moderate-to-vigorous PA (MVPA) and vigorous PA were objectively measured by accelerometry. We observed that the percent of energy derived from fat intake was significantly associated with FMI and FMI/LMI ratio (Ps = 0.001) and greater amounts of truncal (P = 0.001) and abdominal adiposity in the three regions regardless of age, sex and height (all P ≤ 0.005). The strength of the relationships was not substantially altered by further adjustment for PA, vigorous PA or moderate-to-vigorous PA (Ps ≤ 0.005). The percent of energy derived from dietary fat intake is strongly and linearly associated with total, truncal and abdominal adiposity independently of PA in adolescents. These observations implicate the amount of dietary fat intake as a specific risk factor in the excess of abdominal adiposity in adolescence.

    As the incidence of childhood obesity increases, there is a need to promote leisure time physical activity. Traditional approaches to promote the population physical activity levels have shown at best moderate improvements. High percentage of children today carry a cell phone, thus the use of this portable device seems promising for enhancing physical activity. Pokémon Go, is a smartphone game that uses augmented reality, where players are incentivized to get out and walk significant distances to catch the Pokémon. Initial reports suggested increases in the number of steps that players performed, yet this effect of the game was not sustained. Incorporating physical activity into modern technology seems promising, clearly there is need to explore creative ways to achieve a longer term effect.

    Schools represent an important environment for physical activity (PA) promotion among youth. Schools can promote PA through policies and programs but our understanding of how these school characteristics associate with student PA levels is largely unknown. Developing this understanding is critical for implementing new prevention interventions. The aim of this study was to identify the school- and student-related characteristics associated with moderate and high levels of PA in a sample of Ontario elementary schools. Using multi-level logistic regression analyses, we explored the school- and student-level characteristics associated with being moderately and highly active using data collected from administrators and from students in grades 5 to 8 at 30 elementary schools in Ontario. Students' PA levels, sex, grade, and the number of physical education classes per week were linked to school environment data--specifically, a school's chosen implementation model for daily physical activity and whether it offers intramural and interschool PA programming. Findings indicate that there was significant between-school variation for being moderately and highly active. Students were less likely to be moderately or highly active if they attended a school offering interschool PA programming. An important student characteristic positively associated with student PA levels included participating in at least two physical education classes per week. The residual differences in PA by school suggest that school-level characteristics facilitate higher levels of student PA beyond individual-level factors. Although most variation in student PA lies between students within schools, there is sufficient between-school variation to be of interest to practitioners and policy-makers.

    Full Text Available Motivation of teachers for professional-pedagogical activity and levels of forming of their pedagogical skills were determined based on the results of self evaluation and evaluation that was performed by the students. Evaluation of teachers' pedagogical skills and self evaluation were compared to dominating motivation for professional activity of teachers. 42 teachers and 78 students took part in this experiment. To determine proffessional-pedagogical activity motivation the tool of K. Zamfir in modification by A. Rean was used. To determine self evaluation of pedagogical skills "Scale of self evaluation of pedagogical activity" and tool of B. Zelentsov "Students about a teacher" were used. It was shown that it is characteristic for teachers to over estimate their pedagogical skills in comparison to the evaluation made by students: high level of forming of pedagogical skills comprise 40,48 % of respondents, while according to the students evaluation this figure is almost twice lower and comprises - 21,43%; average level evaluation, shows only 14,28 %, when students evaluate that 35,71% of teachers have average level of pedagogical skills forming. It was declared that teachers with the most determined internal motives are more objective in their self evaluation. It was proven that teachers whose pedagogical skills are on high level and who are evaluated by the students on the same level the are lead by domination of internal motivation.

    Full Text Available Hormone secretion during physical activity of specific duration and intensity is part of the stress response. In a study to investigate the secretion of ß-endorphin, leucine enkephalin and other recognised stress hormones during physical exercise, blood samples were taken from fourteen (14 healthy, male athletes who competed in a 21 km roadrace. Blood samples were collected before and after completion of the race. This study shows that ß-endorphin/ß-lipotropin, leucine enkephalin, prolactin, and melatonin may be classified as stress hormones in physical activity of duration 80 to 120 minutes and intensity exceeding 75%-V0₂max. Widespread intra-individual variation in serum cortisol concentrations prevent definite conclusion. The un­expected increase in serum testosterone levels warrants further research.

    This study focused on the perceived climate for LGBT youth and other minority groups in physical activity settings. A large sample of undergraduates and a selected sample including student teachers/interns and a campus Pride group completed a school climate survey and rated the climate in three physical activity settings (physical education, organized sport, exercise). Overall, school climate survey results paralleled the results with national samples revealing high levels of homophobic remarks and low levels of intervention. Physical activity climate ratings were mid-range, but multivariate analysis of variation test (MANOVA) revealed clear differences with all settings rated more inclusive for racial/ethnic minorities and most exclusive for gays/lesbians and people with disabilities. The results are in line with national surveys and research suggesting sexual orientation and physical characteristics are often the basis for harassment and exclusion in sport and physical activity. The current results also indicate that future physical activity professionals recognize exclusion, suggesting they could benefit from programs that move beyond awareness to skills and strategies for creating more inclusive programs.

    Physical activity (PA) promotes weight maintenance, potentially because of its beneficial effects on feeding behavior regulation via diminished food cue reactivity within brain reward regions. This study examined how levels of PA and sedentary behavior (SB) relate to brain responses to food cues. Participants (22 lean, 18 with obesity) completed three to five PA recalls over 2 months. Average minutes per day of moderate to vigorous PA (MVPA) and SB were calculated. Participants completed a functional magnetic resonance imaging session, viewing food and nonfood images following glucose ingestion. Region of interest (ROI) analysis examined associations between MVPA and brain percent signal change in response to food versus nonfood images, controlling for obesity and sex. Secondary analysis examined associations between SB and brain responses to food cues. Greater MVPA was associated with decreased food cue reactivity after glucose across brain ROIs (β = -0.00057, P = 0.005), controlling for obesity and sex. Greater SB was associated with increased food cue reactivity after glucose across brain ROIs in unadjusted analyses (β = 0.00041, P = 0.026). PA may have beneficial effects on brain regulation of feeding behavior after caloric intake in lean individuals and individuals with obesity. © 2018 The Obesity Society.

    We have previously described a theoretical model in humans, called "Similarities in the Inequalities", in which extremely unequal social backgrounds coexist in a complex scenario promoting similar health outcomes in adulthood. Based on the potential applicability of and to further explore the "similarities in the inequalities" phenomenon, this study used a rat model to investigate the effect of different nutritional backgrounds during gestation on the willingness of offspring to engage in physical activity in adulthood. Sprague-Dawley rats were time mated and randomly allocated to one of three dietary groups: Control (Adlib), receiving standard laboratory chow ad libitum; 50% food restricted (FR), receiving 50% of the ad libitum-fed dam's habitual intake; or high-fat diet (HF), receiving a diet containing 23% fat. The diets were provided from day 10 of pregnancy until weaning. Within 24 hours of birth, pups were cross-fostered to other dams, forming the following groups: Adlib_Adlib, FR_Adlib, and HF_Adlib. Maternal chow consumption and weight gain, and offspring birth weight, growth, physical activity (one week of free exercise in running wheels), abdominal adiposity and biochemical data were evaluated. Western blot was performed to assess D2 receptors in the dorsal striatum. The "similarities in the inequalities" effect was observed on birth weight (both FR and HF groups were smaller than the Adlib group at birth) and physical activity (both FR_Adlib and HF_Adlib groups were different from the Adlib_Adlib group, with less active males and more active females). Our findings contribute to the view that health inequalities in fetal life may program the health outcomes manifested in offspring adult life (such as altered physical activity and metabolic parameters), probably through different biological mechanisms.

    Objectives The health benefits of professional sport dissipate after retirement unless an active lifestyle is adopted, yet reasons for adopting an active or inactive lifestyle after retirement from sport are poorly understood. Elite cricket is all-encompassing, requiring a high volume of activity and unique physical demands. We aimed to identify influences on physical activity behaviours in active and insufficiently active former elite cricketers and provide practical strategies for promoting physical activity after cricket retirement. Design 18 audio-recorded semistructured telephone interviews were performed. An inductive thematic approach was used and coding was iterative and data-driven facilitated by NVivo software. Themes were compared between sufficiently active and insufficiently active participants. Setting All participants formerly played professional cricket in the UK. Participants Participants were male, mean age 57±11 (range 34–77) years, participated in professional cricket for 12±7 seasons and retired on average 23±9 years previously. Ten participants (56%) were classified as sufficiently active according to the UK Physical Activity Guidelines (moderate-intensity activity ≥150 min per week or vigorous-intensity activity ≥75 min per week). Eight participants did not meet these guidelines and were classified as insufficiently active. Results Key physical activity influences were time constraints, habit formation, intrinsic and extrinsic motivation, physical activity preferences, pain/physical impairment and cricket coaching. Recommendations for optimising physical activity across the lifespan after cricket retirement included; prioritise physical activity, establish a physical activity plan prior to cricket retirement and don’t take a break from physical activity, evaluate sources of physical activity motivation and incorporate into a physical activity plan, find multiple forms of satisfying physical activity that can be adapted to

    Full Text Available Objective: There are many causes for obesity; inappropriate dietary patterns, inadequate physical activity, and lethargic lifestyle can be mentioned as the main and most important of these causes. Due to the increasing prevalence of obesity in society, it seems necessary to study its causes and find ways to tackle this problem. Materials and Methods: This descriptive-analytical study was conducted on 380 female high school students from district 5 of Tehran, Iran, in 2012. In this research, physical activity was measured using the International Physical Activity Questionnaire (IPAQ, and dietary pattern was measured using the Food Frequency Questionnaire (FFQ. Body mass index (BMI was also calculated. In addition, for measurement of aerobic and anaerobic powers, the 540-meter sprint and vertical jump test (Sargent Jump Test were applied. Gathered data was analyzed using SPSS software. Results: The findings of the present study show that 24.7% of the population was overweight and obese, 67% of normal weight (natural, and 8.2% underweight (thin. Chi-square test on breakfast and classification of weight (r = -0.285 and P = 0.002 showed a negative relationship between obesity and eating breakfast. Moreover, it showed a significant positive correlation between watching television and working on the computer, and obesity. Conclusion: According to the results of this research, there is a positive and direct relationship between obesity and lack of exercise and fast food intake (P < 0.05. There is also a positive and direct relationship between physical fitness, and amount of physical activity and fruit and vegetables intake (P < 0.05.

    Full Text Available Abstract Background In order to improve the transition from an intention to a change in health behaviour, action planning is a frequently used behavioural change method. The quality of action plans in terms of instrumentality and specificity is important in terms of supporting a successful change in health behaviour. Until now, little has been known about the predictors of action plan generation and the predictors of high quality action plans and, therefore, the current study investigates these predictors. Method A randomised controlled trial was conducted to improve physical activity (PA and fruit and vegetable (FV consumption using a web-based computer tailored intervention. During the 8-week intervention period, participants in the intervention arm (n = 346 were guided (step-by-step to generate their own action plans to improve their health behaviours. Demographic characteristics, social cognitions, and health behaviour were assessed at baseline by means of self-reporting. Whether participants generated action plans was tracked by means of server registrations within two modules of the intervention. Results The action planning component of the intervention regarding physical activity and fruit and vegetable consumption was used by 40.9 and 20.7 % of the participants, respectively. We found that participants who were physically active at baseline were less likely to generate action plans concerning physical activity. With regards to generating fruit and vegetable action plans, participants with a high risk perception and a strong intention to eat fruit and vegetables on a daily basis made more use of the action planning component for this behaviour. Finally, the large majority of the action plans for physical activity (96.6 % and fruit and vegetable consumption (100 % were instrumental and about half of the action plans were found to be highly specific (PA = 69.6 %/FV = 59.7 %. The specificity of the action plans is associated

    Background To determine whether the provision of higher levels of compulsory school physical activity is associated with higher physical activity and fitness levels and less overweight in childhood and 20 years later. Methods As part of the 1985 Australian Schools Health and Fitness Survey, 109 schools reported how much compulsory physical education (PE) and school sport they provided and were classified as low (compulsory physical activity schools by tertile cutpoints. 6,412 children reported frequency and duration of school (PE and sport) and non-school (commuting and non-organised exercise) physical activity and had height and weight measured; overweight was defined using body mass index (BMI) (m/kg2) cutpoints. 9, 12 and 15 year-olds (n = 2,595) completed a cycle ergometer fitness test (physical working capacity at heart rate 170, PWC170). At follow-up in 2004–5, 2,346 participants kept a pedometer record, completed the International Physical Activity Questionnaire and/or a PWC170 fitness test; and had height and weight measured (overweight = BMI≥25 m/kg2). Results At baseline and follow-up, median total physical activity, fitness and BMI were similar in participants who attended low, medium and high physical activity schools, and those attending high physical activity schools reported only modestly higher school physical activity. There was no difference in the prevalence of high total physical activity and fitness levels in childhood or adulthood across compulsory school physical activity categories. The prevalence of overweight in childhood and adulthood was similar across low, medium and high compulsory physical activity schools. Conclusion The amount of compulsory physical activity reported by schools was not associated with total physical activity, fitness or overweight in childhood or in adulthood. Policies promoting amounts of compulsory school physical activity in this range may not be sufficient to increase physical activity and fitness or reduce

    Sales of calcium supplements have increased dramatically since 1983, as middle-aged women seek to prevent or treat bone loss due to osteoporosis. However, epidemiologic studies have failed to support the hypothesis that larger amounts of calcium are associated with increased bone density or a decreased incidence of fractures. The authors examine the evidence from controlled trials on the effects of calcium supplementation and physical activity on bone loss and find that weight-bearing activit...

    The present study aimed at comparing demographic variables, physical activity level, and health-related anthropometric indicators according to somatotype among physically active individuals. This is a descriptive cross-sectional study, in which the sample consisted of 304 individuals, who are users of the jogging track at the Federal University of Pernambuco (UFPE) in Recife, state of Pernambuco, northeastern Brazil. Somatotypes were analyzed using the anthropometric technique proposed by Heath & Carter (1990). To assess physical activity level, we used the short version of the International Physical Activity Questionnaire (IPAQ). We used as health-related anthropometric indicators: body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR), and conicity index (CI). We used descriptive statistics to characterize the sample, and then used a multivariate analysis of variance (a = 0.05) to test for differences. In the somatotype analysis, we observed among women significant predominance of the endomorphy and lower predominance of the ectomorphy in comparison to men. In the age group ≤ 29 years significantly lower values were found for endomorphy than in other age groups. Irregularly active individuals had significantly lower values of endomorphy. We observed that individuals with obesity and risk in WHR, WC and CI had higher scores of endomorphy and mesomorphy and lower scores of ectomorphy. The somatotype of physically active individuals in the present study raises health concern, mainly related to high relative adiposity represented by endomorphy.

    Physical inactivity is a growing public health problem, and the fourth leading risk factor for global mortality. Conversely, indigenous populations living traditional lifestyles reportedly engage in vigorous daily activity that is protective against non-communicable diseases. Here we analyze physical activity patterns among the Tsimane, forager-horticulturalists of Amazonian Bolivia with minimal heart disease and diabetes. We assess age patterns of adult activity among men and women, test whether modernization affects activity levels, and examine whether nascent obesity is associated with reduced activity. A factorial method based on a large sample of behavioral observations was employed to estimate effects of age, sex, body mass index, and modernization variables on physical activity ratio (PAR), the ratio of total energy expenditure to basal metabolic rate. Accelerometry combined with heart rate monitoring was compared to the factorial method and used for nighttime sampling. Tsimane men and women display 24 hr physical activity level (PAL) of 2.02-2.15 and 1.73-1.85, respectively. Little time was spent "sedentary", whereas most activity was light to moderate, rather than vigorous. Activity peaks by the late twenties in men, and declines thereafter, but remains constant among women after the early teens. Neither BMI, fat free mass or body fat percentage are associated with PAR. There was no negative effect of modernization on physical activity. Tsimane display relatively high PALs typical of other subsistence populations, but of moderate intensity, and not outside the range of developed populations. Despite rapidly increasing socioeconomic change, there is little evidence that total activity has yet been affected. Overweight and obesity are more prevalent among women than men, and Spanish fluency is associated with greater obesity in women. The lack of cardiovascular disease among Tsimane is unlikely caused by activity alone; further study of diet, food intake and

    an association exists between knowledge and performed PA within contemporary curricula in first grade high school students. METHODS: Overall, 75 students participated in our experimental survey, 33 boys and 42 girls from three grammar schools and one vocational school. At the beginning of the monitoring these students completed "Comprehension test (CT on health and physical activity" and the ANEWS questionnaire (Abbreviated Neighbourhood Environment Walkability Scale. For the whole month they monitored daily number of steps using Yamax Digiwalker SW-700 pedometer and recorded their number of steps into personal log. At the end, after one week break in monitoring, students again completed CT and the IPAQ questionnaire (International Physical Activity Questionnaire – long version. During detailed analysis of the relationship between knowledge on PA and PA, we also focused on PA of various intensity and types. RESULTS: We found out that girls have greater knowledge on PA than boys in all observed dimensions, both in pre-test (18.26 vs. 16.55 points and post-test (18.57 vs. 16.76 points. The correlation coefficient in boys between overall PA and CT was rP = - 0.505 (p < 0.01, and in girls rP = - 0.404 (p < 0.01 which may indicate that knowledge about PA in this age group can be at the expense of realized PA. CONCLUSIONS: An association between knowledge on PA and performed PA was identified and Pearson’s correlation proved negative statistically significant relationship in boys as well as in girls. First grade girls from four high schools showed better results in CT than boys. There is a necessity to carry out similar surveys in other age groups.

    Two models were developed to increase high school students' participation in physical education (PE): "motion enjoyment" and "sport enjoyment". The first model focuses on increasing knowledge about the health benefits of a physically active lifestyle and thereby promoting a positive attitude towards physical activity, whereas the second model focuses on techniques and practices for enhancing athletic performance. The aims of the present study are to investigate and understand the similarities and differences between students selecting "motion enjoyment" vs. "sport enjoyment" and to examine the extent to which life goals and reported physical activity are associated with health-related quality of life (HRQOL). A total of 156 high school students (mean age, 16 years [standard deviation = 0.8], 123 girls and 33 boys) were included in this cross-sectional study. HRQOL and life goals were measured using KIDSCREEN-10 and the Adolescent Life Goal Profile Scale, respectively. Physical activity was measured using a self-reporting questionnaire intended to describe the students' leisure-time activity. Independent sample t-tests, chi-square, one-way analyses of variance and multiple regression analysis were applied. Self-reported physical activity level and HRQOL were higher among students in the "sport enjoyment" program, while the perceived importance of life goals was the same regardless of the preferred PE model. Multiple regression analyses revealed that the perceived importance of relations-oriented life goals (B = -5.61; 95 % confidence interval CI = -10.53 to -0.70; p = .026), perceived importance of generativity-oriented life goals (B = 4.14.; 95 % CI = 0.85 to 7.422; p = .014), perceived attainability of relations-oriented life goals (B = 7.28; 95 % CI = 2.49 to 12.07; p = .003), age (B = -7.29; 95 % CI = -11.38 to -3.20; p = .001) and gender, with boys as the reference group (B = -12.10; 95 % CI

    The aim of this study was to examine the effectiveness of the physical activity (PA) program on weight control, physical fitness, occupational stress, job satisfaction, and quality of life of overweight and sedentary employees in high-tech industries. Participants in the intervention group (n = 37) were instructed to carry out PA program on a moderate intensity for 60 min/session, 3 sessions/week for 12 weeks. Those in the control group (n = 38) received no PA program, were asked to continue their routine lifestyle. Evaluations were performed at baseline and at the end of the intervention. Results of structured questionnaires and blood biochemistry tests and evaluations of physical fitness were analyzed. PA program has effectively reduced the number of risk factors of metabolic syndrome and body fat percentage, and improved the physical fitness such as flexibility, muscular strength and endurance and cardiorespiratory endurance. The intervention has also significantly decreased levels of serum triglyceride, total cholesterol and low-density lipoproteins-cholesterol. Significant positive effects on work control, interpersonal relationship at work, global job satisfaction and quality of life, have also been demonstrated. Results from this study showed that PA program can be helpful in improving physical, physiological and psychological outcomes for overweight and sedentary employees in high-tech industries.

  12. Macronutrient Intake for Physical Activity

    Science.gov (United States)

    Buford, Thomas

    Proper nutrition is an essential element of athletic performance, body composition goals, and general health. Although natural variability among persons makes it impossible to create a single diet that can be recommended to all; examining scientific principles makes it easier for athletes and other physically active persons to eat a diet that prepares them for successful training and/or athletic competition. A proper nutritional design incorporates these principles and is tailored to the individual. It is important for the sports nutritionist, coach, and athlete to understand the role that each of the macronutrients plays in an active lifestyle. In addition, keys to success include knowing how to determine how many calories to consume, the macronutrient breakdown of those calories, and proper timing to maximize the benefits needed for the individual's body type and activity schedule.

Cross-sectional survey data and measured height and weight from 1985 (n=557) and 2001 (n=926) were compared for children aged between 9-13 years within high and low SES areas. From 1985 to 2001, the frequency of walking to or from school declined (4.38 +/- 4.3 vs. 3.61 +/- 3.8 trips/wk, ptrips/wk, ptime as increases in overweight and obesity among Australian children. Promoting active school transport and maintaining school sport and PE should be important public health priorities in Australia. Current inequities in school sport and PE and in prevalence of overweight and obesity by area-level SES also need to be addressed.

    2013-05-01

    Patients with CKD are characterized by low levels of physical functioning, which, along with low physical activity, predict poor outcomes in those treated with dialysis. The hallmark of clinical care in geriatric practice and geriatric research is the orientation to and assessment of physical function and functional limitations. Although there is increasing interest in physical function and physical activity in patients with CKD, the nephrology field has not focused on this aspect of care. This paper provides an in-depth review of the measurement of physical function and physical activity. It focuses on physiologic impairments and physical performance limitations (impaired mobility and functional limitations). The review is based on established frameworks of physical impairment and functional limitations that have guided research in physical function in the aging population. Definitions and measures for physiologic impairments, physical performance limitations, self-reported function, and physical activity are presented. On the basis of the information presented, recommendations for incorporating routine assessment of physical function and encouragement for physical activity in clinical care are provided.

    2016-01-01

    A formal course in physics is increasingly becoming a standard requirement in the high school curriculum. With that dissemination comes the challenge of reaching and motivating a population that is more diverse in their academic abilities and intrinsic motivation. The abstract nature of pure physics is often made more accessible when motivated by examples from everyday life, and providing copious mathematical as well as conceptual examples has become standard practice in high school physics textbooks. Astronomy is a naturally captivating subject and astronomical examples are often successful in capturing the curiosity of high school students as well as the general population. This project seeks to diversify the range of pedagogical materials available to the high school physics instructor by compiling and publishing specific examples where an astronomical concept can be used to motivate the physics curriculum. This collection of examples will consist of both short problems suitable for daily homework assignments as well as longer project style activities. Collaborations are encouraged and inquiries should be directed to sdieterich at carnegiescience dot edu.This work is funded by the NSF Astronomy and Astrophysics Postdoctoral Fellowship Program through NSF grant AST-1400680.

    The purposes of this study were to determine: (i) the extent of an acute session of high-intensity intermittent exercise (HIIE) followed by a concurrent strength session (Conc) on the increase of systemic inflammatory cytokines and chemokines, and (ii) whether eight weeks of high intensity interval training plus concurrent strength training alters the acute inflammatory response and immune status. Ten recreationally active males (aged 26.9±4.3years) performed two experimental exercise sessions interspersed by eight weeks of HIIT plus concurrent strength training. The experimental exercise session was composed of a 5-km run on a treadmill (1:1 at 100% of maximal aerobic speed (MAS)), and after 10min of passive recovery, back squat exercises were performed (80% 1RM, four sets until exhaustion). Serum samples were collected after fasting, pre-HIIE, post-HIIE, Pre-Conc, Post-Conc, and 30 and 60min post-exercise session. The comparison between both concurrent exercise sessions was performed using repeated measure ANOVA, with the Bonferroni Post-hoc when necessary. Interleukin-6 (IL-6) presented a moment effect (F=6.72; p<0.05), with Post-Conc significantly higher than pre-HIIE, Post-HIIE, and 60min, only a tendency was found between pre-HIIE and post-HIIE (difference=-5.99; p=0.09). MCP-1 and IL-1ra did not present effects for condition, moment, or interaction. Interleukin-10 (IL-10) presented both moment and interaction effects (F=5.31 and 2.50; p=0.005 and 0.036). Pre-Conc and Post-Conc were significantly higher than Pre-HIIE. The interaction between before and after eight weeks of concurrent training probably occurred at Post-Conc (11.42±3.09pgmL -1 and 8.88±1.29pgmL -1 ). In addition, maintenance of immune function was observed. Therefore, HIIE and concurrent strength exercise lead to an increase in cytokines response, but eight weeks of training program promoted anti-inflammatory response after an acute session of concurrent exercise.

    In these three lectures I discuss the present status of high-energy astroparticle physics including Ultra-High-Energy Cosmic Rays (UHECR), high-energy gamma rays, and neutrinos. The first lecture is devoted to ultra-high-energy cosmic rays. After a brief introduction to UHECR I discuss the acceleration of charged particles to highest energies in the astrophysical objects, their propagation in the intergalactic space, recent observational results by the Auger and HiRes experiments, anisotropies of UHECR arrival directions, and secondary gamma rays produced by UHECR. In the second lecture I review recent results on TeV gamma rays. After a short introduction to detection techniques, I discuss recent exciting results of the H.E.S.S., MAGIC, and Milagro experiments on the point-like and diffuse sources of TeV gamma rays. A special section is devoted to the detection of extragalactic magnetic fields with TeV gammaray measurements. Finally, in the third lecture I discuss Ultra-High-Energy (UHE) neutrinos.

    Full Text Available Parents influence on their young children's physical activity (PA behaviours was examined in a sample of 102 preschool-aged children (54 boys. Questionnaires regarding family sociodemographics and physical activity habits were completed. Results showed that children who received greater parental support for activity (B=.78, P<.10 and had parents who rated PA as highly enjoyable (B=.69, P<.05 were significantly more likely to engage in one hour or more of daily PA. Being an older child (B=−.08, P<.01, having older parents (B=−.26, P<.01, and watching more than one hour of television/videos per day (B=1.55, P<.01 reduced the likelihood that a child would be rated as highly active. Children who received greater parental support for PA were 6.3 times more likely to be highly active than inactive (B=1.44, P<.05. Thus, parents can promote PA among their preschoolers, not only by limiting TV time but also by being highly supportive of their children's active pursuits.

    Pelvic floor disorders are common, with 1 in 4 US women reporting moderate to severe symptoms of urinary incontinence, pelvic organ prolapse, or fecal incontinence. Given the high societal burden of these disorders, identifying potentially modifiable risk factors is crucial. Physical activity is one such potentially modifiable risk factor; the large number of girls and women participating in sport and strenuous training regimens increases the need to understand associated risks and benefits of these exposures. The aim of this review was to summarize studies reporting the association between physical activity and pelvic floor disorders. Most studies are cross-sectional and most include small numbers of participants. The primary findings of this review include that urinary incontinence during exercise is common and is more prevalent in women during high-impact sports. Mild to moderate physical activity, such as brisk walking, decreases both the odds of having and the risk of developing urinary incontinence. In older women, mild to moderate activity also decreases the odds of having fecal incontinence; however, young women participating in high-intensity activity are more likely to report anal incontinence than less active women. Scant data suggest that in middle-aged women, lifetime physical activity increases the odds of stress urinary incontinence slightly and does not increase the odds of pelvic organ prolapse. Women undergoing surgery for pelvic organ prolapse are more likely to report a history of heavy work than controls; however, women recruited from the community with pelvic organ prolapse on examination report similar lifetime levels of strenuous activity as women without this examination finding. Data are insufficient to determine whether strenuous activity while young predisposes to pelvic floor disorders later in life. The existing literature suggests that most physical activity does not harm the pelvic floor and does provide numerous health benefits for

    Full Text Available Abstract Background Cardiovascular risk factors are associated with physical fitness and, to a lesser extent, physical activity. Lifestyle interventions directed at enhancing physical fitness in order to decrease the risk of cardiovascular diseases should be extended. To enable the development of effective lifestyle interventions for people with cardiovascular risk factors, we investigated motivational, social-cognitive determinants derived from the Theory of Planned Behavior (TPB and other relevant social psychological theories, next to physical activity and physical fitness. Methods In the cross-sectional Utrecht Police Lifestyle Intervention Fitness and Training (UP-LIFT study, 1298 employees (aged 18 to 62 were asked to complete online questionnaires regarding social-cognitive variables and physical activity. Cardiovascular risk factors and physical fitness (peak VO2 were measured. Results For people with one or more cardiovascular risk factors (78.7% of the total population, social-cognitive variables accounted for 39% (p In addition to the prediction of intention to engage in physical activity and physical active behavior, we explored the impact of the intensity of physical activity. The intentsity of physical activity was only significantly related to physical active behavior (beta = .253, p 2 = .06, p 2 = .23, p For people with one or more cardiovascular risk factors, 39.9% had positive intentions to engage in physical activity and were also physically active, and 10.5% had a low intentions but were physically active. 37.7% had low intentions and were physically inactive, and about 11.9% had high intentions but were physically inactive. Conclusions This study contributes to our ability to optimize cardiovascular risk profiles by demonstrating an important association between physical fitness and social-cognitive variables. Physical fitness can be predicted by physical active behavior as well as by self-efficacy and the intensity of

This research places inside the methodology of quantitative type of descriptive cut, across survey, which has been in use as instrument of withdrawal of information the interview standardized by means of questionnaire created ad hoc, that was completed by 300 teachers. In the study there is obtained that the vast majority of the teachers who give classes in the extracurricular physical activities say they do not establish any coordination with the Physical Education teacher of the school. However, most of these teachers feel they would be good if there were a coordination with the teachers of Physical Education. However, more than half of teachers who give classes in the extracurricular physical activities believe that the objectives of the activities they provide are not related to the objectives of the Physical Education.

    A cross-cultural, randomized study was proposed to observe the effects of a school-based intervention designed to promote physical activity and healthy eating among high school students in 2 cities from different regions in Brazil: Recife and Florianopolis. The objective of this article is to describe the methodology and subjects enrolled in the project. Ten schools from each region were matched and randomized into intervention and control conditions. A questionnaire and anthropometry were used to collect data in the first and last month of the 2006 school year. The sample (n=2155 at baseline; 55.7% females; 49.1% in the experimental group) included students 15 to 24 years, attending nighttime classes. The intervention focused on simple environmental/organizational changes, diet and physical activity education, and personnel training. The central aspects of the intervention have been implemented in all 10 intervention schools. Problems during the intervention included teachers' strikes in both sites and lack of involvement of the canteen owners in schools. The Saude na Boa study provides evidence that public high schools in Brazil represent an important environment for health promotion. Its design and simple measurements increase the chances of it being sustained and disseminated to similar schools in Brazil.

    Physical activity and physical fitness are important for health, functional mobility and performance of everyday activities. To date, little attention has been given to physical activity and physical fitness among nursing home residents with cognitive impairment. Therefore, the main aim of this study was to examine physical activity behavior and physical fitness of institutionalized older adults with cognitive impairment and to investigate their interrelations. Forty-eight older adults with cognitive impairment (83.9±7.7years; 72.9% women) and 22 without cognitive impairment (82.2±8.8years; 54.5% women) participated. Physical activity was objectively assessed with accelerometers and physical fitness components (muscular strength, flexibility, balance, body composition and reaction time) were evaluated with physical fitness field tests. Nursing home residents with cognitive impairment spent only ~1min per day in moderate physical activity and ~89min in light physical activity. In average they accumulated 863 (±599) steps per day and spent 87.2% of the accelerometer wear time in sedentary behavior. Participants' physical fitness components were markedly low and according to the cut-offs used for interpreting the results a great number of nursing home residents had an increased risk of associated health problems, functional impairment and of falling. The performance in some physical fitness tests was positively associated with physical activity. Participants without cognitive impairment had higher levels of physical activity and physical fitness than their counterparts with cognitive impairment. These results indicate that nursing home residents, especially those with cognitive impairment, have low levels of physical activity, spent a high proportion of daytime in sedentary behavior and have low physical fitness. Nursing homes should implement health promotion strategies targeting physical activity and physical fitness of their residents. Copyright © 2017 Elsevier

The primary outcome measures were grouped according to whether they were dichotomous (per cent physically active, per cent physically active during leisure time, and per cent physically inactive) or continuous (leisure time physical activity time (time spent)), walking (time spent), energy expenditure (as metabolic equivalents or METS)). For dichotomous measures we calculated the unadjusted and adjusted risk difference, and the unadjusted and adjusted relative risk. For continuous measures we calculated percentage change from baseline, unadjusted and adjusted. After the selection process had been completed, 33 studies were included. A total of 267 communities were included in the review (populations between 500 and 1.9 million). Of the included studies, 25 were set in high income countries and eight were in low income countries. The interventions varied by the number of strategies included and their intensity. Almost all of the interventions included a component of building partnerships with local governments or non-governmental organisations (NGOs) (29 studies). None of the studies provided results by socio-economic disadvantage or other markers of equity. However, of those included studies undertaken in high income countries, 14 studies were described as being provided to deprived, disadvantaged or low socio-economic communities. Nineteen studies were identified as having a high risk of bias, 10 studies were unclear, and four studies had a low risk of bias. Selection bias was a major concern with these studies, with only five studies using randomisation to allocate communities. Four studies were judged as being at low risk of selection bias although 19 studies were considered to have an unclear risk of bias. Twelve studies had a high risk of detection bias, 13 an unclear risk and four a low risk of bias. Generally, the better designed studies showed no improvement in the primary outcome measure of physical activity at a population level.All four

    Drukarev, Evgeny G

    2016-01-01

    This self-contained text introduces readers to the field of high-energy atomic physics - a new regime of photon-atom interactions in which the photon energies significantly exceed the atomic or molecular binding energies, and which opened up with the recent advent of new synchrotron sources. From a theoretical point of view, a small-parameter characteristic of the bound system emerged, making it possible to perform analytic perturbative calculations that can in turn serve as benchmarks for more powerful numerical computations. The first part of the book introduces readers to the foundations of this new regime and its theoretical treatment. In particular, the validity of the small-parameter perturbation expansion and of the lowest-order approximation is critically reviewed. The following chapters then apply these insights to various atomic processes, such as photoionization as a many-body problem, dominant mechanisms for the production of ions at higher energies, Compton scattering and ionization accompanied b...

    This article examines the association of family history of heart disease and leisure-time physical activity with incident heart disease. The data are from the 1994/95, 1996/97 and 1998/99 longitudinal household components of Statistics Canada's National Population Health Survey. This study is based on information provided by 9,255 respondents aged 20 or older who reported that, in 1994/95, they were free of diagnosed heart disease and in good health. Multiple logistic regression was used to estimate the association of family history and physical activity with a new diagnosis of heart disease, while controlling for age, sex, educational attainment, smoking, high blood pressure, diabetes, and body mass index. When family history and other risk factors were taken into account, people who, in 1994/95, engaged in regular physical activity at a moderate level or beyond had lower odds of receiving a new diagnosis of heart disease than did sedentary individuals. People with a family history of heart disease who regularly participated in at least moderate physical activity had lower odds of developing heart disease than did their sedentary counterparts.

    2003-01-01

    To determine the test-retest reliability of items measuring habitual incidental physical activity, incidental physical activity behaviour and sedentary behaviours. Eighty-four subjects aged 18-65 years were interviewed from randomly selected households within metropolitan and rural Western Australia. Subjects were administered the interview on two separate occasions 10 days apart. Subjects were asked about habitual incidental physical activity (i.e. bouts performed for 10 minutes or less) performed during the week and on weekends. Intraclass correlations performed for items measuring incidental physical activity were generally found to be low to moderate. The frequency of incidental physical activity was more reliably recalled than the average duration spent on short trips (ICC 0.582 to 0.872 compared with 273 to 0.551). Kappa coefficients for habitual incidental physical activity behaviour items were observed to have moderate-to-high (0.478 to 0.939) agreement between administrations. Sedentary behaviours overall showed high test-retest reliability (ICC 0.646 to 0.925). These findings demonstrate that adults can reliably recall the frequency, but not the duration, of habitual incidental physical activity. Thus, the frequency measured by these items could be used to determine the effectiveness of current Australian physical activity guidelines and possibly identify shifts in incidental physical activity behaviour over time. Measurement of physical activity in all domains including incidental physical activity is required to determine the effectiveness of current guidelines and implemented health promotion interventions.

    Full Text Available This study explored the physical activities of fifth and sixth graders that projected correlations to science performance and how these physical activities may be utilized for classroom purposes in the context of science-related play activities. Descriptive survey correlational design directed the data collection and analysis of the physical activities of purposively selected 133 fifth and sixth graders. Primarily, the study used a researcher-developed and validated instrument (Physical Activity Questionnaire [PAQ], and standard instruments: Philippine National Physical Activity Guide (PNPAG and General Physical Activity Questionnaire (GPAQ. The latter classified the physical activities into five domains which directed the interpretation of the participants‟ responses. The Pearson-r Moment of Correlation described the level of correlation of the frequency of engagement to physical activities (limited to local and localized activities and the science grade of the respondents. Results show that each of the physical activity domains showed specific correlations to science performance of the respondents. For further research, enrichment of the relationship of the physical activities and the science performance may focus on possible moderating variables like economic status, and time allotment for physical activities.

Comparative deconditioning from the previous day for the test Baevsky 3,09%, can be used for operational planning of physical activity of high intensity on that day.

  13. Pro-opiomelanocortin modulates the thermogenic and physical activity responses to high-fat feeding and markedly influences dietary fat preference.

    Tung, Y C Loraine; Rimmington, Debra; O'Rahilly, Stephen; Coll, Anthony P

    2007-11-01

    Complete proopiomelanocortin (POMC) deficiency causes a human syndrome of hypoadrenalism, altered skin and hair pigmentation, and severe hyperphagic obesity. Heterozygote carriers of nonsense mutations are strongly predisposed to obesity. Pomc(+/-) mice have normal body weight on a chow diet but increase food intake and become more obese than wild-type littermates when placed on a high-fat diet. To further explore the mechanisms whereby dietary fat interacts with Pomc genotype to produce obesity, we examined Pomc-null, Pomc(+/-), and wild-type mice for changes in the components of energy balance in response to provision of a high-fat diet and macronutrient preference when presented with a selection of dietary choices. In contrast to wild-type mice, Pomc null mice did not increase their resting energy expenditure or their spontaneous physical activity when given a high-fat diet. Pomc(+/-) mice increased resting energy expenditure similarly to wild types, but their increase in physical activity was significantly less than that seen in wild-type mice. In two independent experimental tests of macronutrient preference, Pomc genotype was a strong predictor of dietary fat preference with Pomc null animals choosing to eat approximately twice as much fat, but similar amounts of carbohydrate and protein, as wild-type animals. Pomc(+/-) mice showed an intermediate response. In summary, POMC-derived peptides have influences on multiple aspects of the organism's response to the presentation of high-fat diet. This includes a major influence, readily discernible even in heterozygote animals, on the dietary preference for fat.

    Deuteron-induced nuclear reactions for generation of no-carrier-added (NCA) Lu isotopes were investigated using the stacked-foil activation technique on natural Yb targets at energies up to Ed=18.18MeV. The decay curve of ¹⁷⁷Yb, the growth curve of the cumulative (direct and indirect) and the direct production of (177g)Lu were determined. The analysis of these curves conducts to the evidence that the predominant route for the production of (177g)Lu is the indirect reaction ¹⁷⁶Yb(d,p)¹⁷⁷Yb, which decays to (177g)Lu. In the spectra acquired one year from the EOB the γ lines of (177m)Lu are not evident. A comparison between the calculated activity of (177g)Lu produced with a cyclotron and with a nuclear reactor is given. Copyright © 2014 Elsevier Inc. All rights reserved.

    Aim. The purpose of this study was to determine the response of circulating markers of lipid and protein oxidation following an incremental test to exhaustion before and after 4 weeks of high-intensity interval training performed in the heat. Methods. To address this question, 16 physically active men (age = 23 ± 2 years; body mass = 73 ± 12 kg; height = 173 ± 6 cm; % body fat = 12.5 ± 6 %; body mass index = 24 ± 4 kg/m(2)) were allocated into 2 groups: control group (n = 8) performing high-intensity interval training at 22°C, 55% relative humidity and heat group (n = 8) training under 35°C, 55% relative humidity. Both groups performed high-intensity interval training 3 times per week for 4 consecutive weeks, accumulating a total of 12 training sessions. Before and after the completion of 4 weeks of high-intensity interval training, participants performed an incremental cycling test until exhaustion under temperate environment (22°C, 55% relative humidity) where blood samples were collected after the test for determination of exercise-induced changes in oxidative damage biomarkers (thiobarbituric acid reactive species and protein carbonyls). Results. When high-intensity interval training was performed under control conditions, there was an increase in protein carbonyls (p high-intensity interval training performed in high environmental temperature enhanced the incremental exercise-induced increases in thiobarbituric acid reactive species (p high-intensity interval training performed in the heat enhances exercise-induced lipid peroxidation, but prevents protein oxidation following a maximal incremental exercise in healthy active men.

    The underlying factors affecting physical activity (PA) participation of children with high-functioning autism spectrum disorders (HFASDs) and their family members were investigated using a mixed method research design. Six families with children with HFASD aged 4 through 13 participated in the study. Findings revealed that levels of moderate to vigorous physical activity (MVPA) in children with HFASD varied between 85 min and 405 min for seven days. Parents of children with HFASD in this study were inactive (levels of MVPA varied between 6 min and 53 min) during this period. Qualitative data from parents highlighted many essential issues. Those issues are categorized under three main themes: (a) understanding PA in children with HFASD, (b) living with a child with HFASD, and (c) awareness of autism spectrum disorders (ASD) at school and community settings. Social skills, issues related to bullying, fear of injury to the child, as well as support from family members and lack of understanding of the disability emerged as subthemes extracted from these data.

    Full Text Available Atheromatosis develops as a result of a chronic inflammatory process of the arteries. Inflammatory biomarkers, particularly high-sensitivity C-reactive protein (hsCRP, positively correlate with atheromatosis risk factors and can be used to estimate and predict the risk of cardiovascular events. The purpose of this study was to evaluate the relationship between hsCRP concentration and BMI, body composition, classical risk factors for cardiovascular diseases, energy expenditure for physical activity (WEE and  ·VO2max. 166 volunteers (78 women and 88 men were included in the examinations. Their mean age was 20.2±0.9 years. Health condition was described by the following variables: smoking, WEE,  ·VO2max, body mass index (BMI, waist-to-hip ratio (WHR, fat mass (FM, fat-free mass (FFM, lipid profile, hsCRP, glucose and insulin concentration, and insulin resistance. Between the subgroups created on the basis of hsCRP concentration, in quartiles 1 to 3 and quartile 4, a comparative analysis was carried out. 79.5�0of women and 69.3�0of men had hsCRP values within the references ranges. Moderately high values were found in 14.1�0of women and 22.7�0of men and high in 6.4�0and 7.9�20respectively. Mean values of BMI, FFM, WHR, WEE,  ·VO2max, glucose and triglyceride concentration, and TC/HDL index were significantly lower, while FM and HDL were significantly higher, in women than in men. In the quartile 4 subgroup compared to the quartile 1-3 subgroup, we found significantly lower HDL concentration and a tendency for higher values of BMI (p=0.06 and TC (p=0.07 as well as higher percentages of smoking among men. In young, physically active, healthy persons, serum concentration of hsCRP is not related to physical activity or  ·VO2max.

    We investigated the possibility of acceleration of ultra-high-energy cosmic rays (UHECRs) in nearby active galactic nuclei (AGNs) using archival multi-wavelength observational data, and then we constrained their physical conditions, I.e., the luminosity of the synchrotron radiation and the size of the acceleration site. First, we investigated the spatial correlation between the arrival directions of UHECRs and the positions of nearby AGNs in the Fermi third gamma-ray source catalog. We selected 27 AGNs as candidates of accelerators of UHECRs. Then, we evaluated the physical conditions in the acceleration regions of these AGNs via the Pe’er and Loeb method, which uses the peak luminosity of synchrotron radiation and the peak flux ratio of inverse Compton scattering to synchrotron radiation. From the evaluation, we found that six AGNs have the ability to accelerate ultra-high-energy (UHE) protons in the AGN cores. Furthermore, we found that the minimum acceleration size must be more than a few kpc for acceleration of UHE protons in the AGN lobes.

    Understanding the determinants of physical activity in children is critical for the treatment and prevention of childhood obesity. Social-cognitive theory has been used to understand behavioral patterns in children. To explore the relationship between health beliefs, self-efficacy, social support, and sedentary activities and physical activity levels in children and to examine the relationship between physical activity and children's self-esteem. Ninety-two children aged 10 to 16 years completed the study. Physical activity was monitored for 1 week with a motion detector (Actitrac; IM Systems, Baltimore, Md). Moderate-level activity and high-level activity were defined based on the results of treadmill testing. Health beliefs, self-efficacy, social influences, and time spent in sedentary behaviors were determined through questionnaires. Self-esteem was measured using the Piers-Harris Children's Self-Concept Scale. Chronic anxiety was measured with the Revised Children's Manifest Anxiety Scale. There was a significant decline in physical activity levels between ages 10 and 16 years, particularly in girls. Preteen girls spent approximately 35% more time in low- and high-level activity than did teenage girls (Pactivity. Time spent in sedentary behaviors was inversely correlated with the amount of moderate-level activity (Plevel activity. In contrast, time spent in high-level activity correlated with self-efficacy scores (Plevel physical activity was also associated with improved self-esteem (Pphysical activity levels. Children and adolescents are largely sedentary. Correlates of high- and low-level physical activity are different. Time spent on sedentary activities is inversely correlated with moderate-level activity, while self-efficacy and social influences are positively correlated with more intense physical activity. In addition, increased high-level physical activity is an important component in the development of self-esteem in children.

    Promotion of physical activity continues to be recommended as an essential component of obesity treatment and prevention interventions. This review explores recent updates in the area of physical activity promotion and its impact on the physical and mental health consequences of childhood obesity. Despite the availability of opportunities for physical activity in the school environment, namely recess and physical education classes, students do not appear to be meeting activity recommendations at school alone. Access to neighborhood parks may increase levels of physical activity and reduce time spent in sedentary behaviors at home. Less time spent watching television and in other sedentary behaviors such as playing videogames may contribute to higher rates of physical activity. Frequency of physical activity also appears to be related to improved mental health status, although the direction of this relationship warrants further exploration. Physical activity is an evidence-based intervention that offers benefits to both physical and mental health. Pediatric health care providers are encouraged to engage in discussions with patients and families on the topic of physical activity and to assist them in finding ways to incorporate activity into daily life.

    Neurological dysfunction is a key medical concern in professional sportsmen (PSM). We investigated whether saliva S100B concentrations in PSM and healthy controls are modified before and after training. We conducted a case-control-study in 75 patients (25 PSM vs 50 controls) in which S100B saliva concentrations were expressed as absolute values and percentage of change (%) from samples drawn before (T0) and after (T1) training. No differences (P>0.05) between groups were found regarding clinical, monitoring and laboratory parameters. S100B both in PSM and controls was higher at T1 when compared to T0 (P<0.01). In PSM, S100B was higher than controls (P<0.001) at T0 and T1. S100B% at T0-T1 was higher (P<0.001) in PSM and in controls and between PSM and controls (P<0.001). Increased saliva S100B levels in PSM before and after training suggest a paracrine/autocrine protein's role connected to stressing activity, which becomes especially evident in PSMs. Copyright © 2010 The Canadian Society of Clinical Chemists.

    Full Text Available Abstract Background Physical inactivity is a leading cause of mortality worldwide. Many patterns of physical activity involvement are established early in life. To date, the role of easily identifiable early-life individual predictors of PA, such as childhood temperament, remains relatively unexplored. Here, we tested whether childhood temperamental activity level, high intensity pleasure, low intensity pleasure, and surgency predicted engagement in physical activity (PA patterns 11 years later in adolescence. Methods Data came from a longitudinal community study (N = 206 participants, 53% females, 70% Caucasian. Parents reported their children’s temperamental characteristics using the Child Behavior Questionnaire (CBQ when children were 4 & 5 years old. Approximately 11 years later, adolescents completed self-reports of PA using the Godin Leisure Time Exercise Questionnaire and the Youth Risk Behavior Survey. Ordered logistic regression, ordinary least squares linear regression, and Zero-inflated Poisson regression models were used to predict adolescent PA from childhood temperament. Race, socioeconomic status, and adolescent body mass index were used as covariates. Results Males with greater childhood temperamental activity level engaged in greater adolescent PA volume (B = .42, SE = .13 and a 1 SD difference in childhood temperamental activity level predicted 29.7% more strenuous adolescent PA per week. Males’ high intensity pleasure predicted higher adolescent PA volume (B = .28, SE = .12. Males’ surgency positively predicted more frequent PA activity (B = .47, SE = .23, OR = 1.61, 95% CI: 1.02, 2.54 and PA volume (B = .31, SE = .12. No predictions from females’ childhood temperament to later PA engagement were identified. Conclusions Childhood temperament may influence the formation of later PA habits, particularly in males. Boys with high temperamental activity level, high intensity

    To understand parents' perspectives of their preschoolers' physical activity behaviours. A maximum variation sample of 71 parents explored their preschoolers' physical activity behaviours through 10 semi-structured focus group discussions. Parents perceived Canada's Physical Activity Guidelines for Children as inadequate; that their preschoolers get and need more than 30-90 minutes of activity daily; and that physical activity habits must be established during the preschool years. Nine barriers against and facilitators toward adequate physical activity were proposed: child's age, weather, daycare, siblings, finances, time, society and safety, parents' impact, and child's activity preferences. The need for education and interventions that address current barriers are essential for establishing physical activity as a lifestyle behaviour during early childhood and, consequently, helping to prevent both childhood and adulthood obesity.

    Background The high prevalence of obesity in America can be attributed to inadequate energy expenditure as a result of high levels of physical inactivity. This review presents an overview of the current literature on physical activity, specifically through active videogame systems (exergaming) and how these systems can help to increase physical activity levels. Methods The search strategy for this review was to identify previous studies which investigated energy expenditure levels using a single active video game or a combination of active videogames. Results Based on data from 27 studies, a strong correlation exists between exergaming and increased energy expenditure (up to 300% above resting levels). The majority of active videogames tested were found to achieve physical activity levels of moderate intensity, which meet American College of Sports Medicine guidelines for health and fitness. Conclusions Exergaming is a new and exciting strategy to potentially improve physical activity levels and reduce obesity among Americans. PMID:25078529

    Physical activity is important for children's health, and identifying factors associated with their physical activity is important for future interventions and public health programs. This study sought to identify multidimensional correlates of preschool children's physical activity. The social-ecological model (SEM) was used to identify constructs potentially associated with preschool children's physical activity. Data were collected from 1004 preschool children, aged 3-5 years, and parents in 2008-2009, and analyzed in 2010-2011. Physical activity was measured over 8 days using ActiGraph accelerometers. Parents completed a comprehensive survey. Generalized linear modeling was used to assess associations between potential correlates and percentage of time spent in physical activity. Correlates of physical activity were found across all the domains of the SEM and varied between boys and girls and week and weekend days. Age was the only consistent correlate, with children spending approximately 10% less time in physical activity for each advancing year of age. Some modifiable correlates that were related to more than one physical activity outcome were rules restricting rough games inside and usual daily sleep time for boys. For girls, a preference to play inside/draw/do crafts rather than be active, and child constraints, was associated with more than one of the physical activity outcomes. A novel finding in this study is the counterintuitive association between parental rules restricting rough games inside and boys' higher physical activity participation levels. Potential strategies for promoting children's physical activity should seek to influence children's preference for physical activity and parent rules. Gender-specific strategies also may be warranted. Copyright © 2012 American Journal of Preventive Medicine. Published by Elsevier Inc. All rights reserved.

    OBJECTIVE To determine effects of restriction feeding of a moderate-protein, high-fiber diet on loss of body weight (BW), voluntary physical activity, body composition, and fecal microbiota of overweight cats. ANIMALS 8 neutered male adult cats. PROCEDURES After BW maintenance for 4 weeks (week 0 = last week of baseline period), cats were fed to lose approximately 1.5% of BW/wk for 18 weeks. Food intake (daily), BW (twice per week), body condition score (weekly), body composition (every 4 weeks), serum biochemical analysis (weeks 0, 1, 2, 4, 8, 12, and 16), physical activity (every 6 weeks), and fecal microbiota (weeks 0, 1, 2, 4, 8, 12, and 16) were assessed. RESULTS BW, body condition score, serum triglyceride concentration, and body fat mass and percentage decreased significantly over time. Lean mass decreased significantly at weeks 12 and 16. Energy required to maintain BW was 14% less than National Research Council estimates for overweight cats and 16% more than resting energy requirement estimates. Energy required for weight loss was 11% more, 6% less, and 16% less than American Animal Hospital Association recommendations for weight loss (80% of resting energy requirement) at weeks 1 through 4, 5 through 8, and 9 through 18, respectively. Relative abundance of Actinobacteria increased and Bacteroidetes decreased with weight loss. CONCLUSIONS AND CLINICAL RELEVANCE Restricted feeding of a moderate-protein, high-fiber diet appeared to be a safe and effective means for weight loss in cats. Energy requirements for neutered cats may be overestimated and should be reconsidered.

    Low levels of physical activity can cause various physical symptoms or illness. However, few studies on this association have been conducted in young adults. The aim of this study was to investigate the association between physical activity levels and physical symptoms or illness in young adults. Subjects were university students who participated in a web-based self-administered questionnaire in a university in Seoul in 2013. We obtained information on physical activities and physical symptoms or illness in the past year. Independent variables were defined as symptoms or illness which were associated with decreased academic performance. Logistic regression was performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs) of each physical symptom or illness with adjustment for covariables. A total of 2,201 participants were included in the study. The main physical symptoms or illness among participants were severe fatigue (64.2%), muscle or joint pain (46.3%), gastrointestinal problems (43.1%), headache or dizziness (38.6%), frequent colds (35.1%), and sleep problems (33.3%). Low physical activity levels were significantly associated with high ORs of physical symptoms or illness. Multivariable-adjusted ORs (95% CIs) in the lowest vs. highest tertile of physical activity were 1.45 (1.14-1.83) for severe fatigue, 1.35 (1.07-1.70) for frequent colds, and 1.29 (1.02-1.63) for headaches or dizziness. We also found that lower levels of physical activity were associated with more physical symptoms or bouts of illness. Low physical activity levels were significantly associated with various physical symptoms or illness among university students. Also, individuals in the lower levels of physical activity were more likely to experience more physical symptoms or bouts of illness than those in the highest tertile of physical activity.

    The prevalence and burden of disease of depression and anxiety disorders in young people necessitates effective early intervention strategies. The aim of this study was to evaluate the effectiveness of low-intensity interventions (problem solving therapy (PST) and physical activity promotion) in young people (15-25 years) with mild-moderate depression and/or anxiety. A 2×2 factorial randomised controlled trial (RCT) with factors of PST versus supportive counselling (control) and behavioural activation physical activity versus lifestyle psychoeducation (control). Help-seeking participants (n=176) were randomised to receive up to 6 manualised intervention sessions. Primary outcomes were post-intervention depressive symptoms (Beck Depression Inventory-II (BDI-II), anxiety symptoms (Beck Anxiety Inventory), and Montgomery-Åsberg Depression Rating Scale (MADRS)). Trial registration ACTRN12608000550303. Depression symptoms were significantly reduced in the physical activity group compared to psychoeducation (BDI-II: d=0.41 (95% CI: 0.07-0.76); MADRS: d=0.48 (95% CI: 0.13-0.82), but not post-intervention anxiety symptoms. PST was not superior to supportive counselling, nor were any interactions between interventions significant. As self reported levels of physical activity did not significantly differ between baseline and end-point in those randomised to the physical activity intervention, it is unclear as to whether some form of physical activity not measured in the trial may have led to the difference in depression symptoms. PST was not superior to supportive counselling in reducing depression and anxiety symptoms in young people. Participants who received the physical activity intervention reported the greatest reduction in depression symptoms, however further research is required to establish the mechanism of action and to determine its effectiveness as an adjunct intervention in routine clinical practice.

    This year the University of Puerto Rico at Mayaguez (UPRM) High Energy Physics (HEP) group continued with the ongoing research program outlined in the grant proposal. The program is centered on the Compact Muon Solenoid (CMS) experiment at the proton-proton (pp) collisions at the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland. The main research focus is on data analysis and on the preparation for the High Luminosity (HL) LHC or experiment detector upgrade. The physics data analysis included Higgs Doublet Search and measurement of the (1) Λ0b branching fraction, (2) B meson mass, and (3) hyperon θ-b lifetime. The detector upgrade included work on the preparations for the Forward Pixel (FPIX) detector Silicon Sensor Testing in a production run at Fermilab. In addition, the group has taken responsibilities on the Software Release through our former research associate Dr. Eric Brownson who acted until last December as a Level Two Offline Manager for the CMS Upgrade. In support of the CMS data analysis activities carried out locally, the UPRM group has built and maintains an excellent Tier3 analysis center in Mayaguez. This allowed us to analyze large data samples and to continue the development of algorithms for the upgrade tracking robustness we started several years ago, and we plan to resume in the near future. This project involves computer simulation of the radiation damage to be suffered at the higher luminosities of the upgraded LHC. This year we continued to serve as a source of outstanding students for the field of high energy physics. Three of our graduate students finished their MS work in May, 2014, Their theses research were on data analysis of heavy quark b-physics. All of them are currently enrolled at Ph.D. physics program across the nation. One of them (Hector Moreno) at New Mexico University (Hector Moreno), one at University of New Hampshire (Sandra Santiesteban) and one at University of

    The present studies adopted the theoretical framework of activity- and purpose-related incentives (Rheinberg, 2008) to explain the maintenance of physical activity. We hypothesized that activity-related incentives (e.g., “fun”) increase more than purpose-related incentives (e.g., “health”) between the initiation and maintenance phase of physical activity. Additionally, change in activity-related incentives was hypothesized to be a better predictor of maintenance of physical activity than chan...

    We previously showed that amyloid-β 1-42 (Aβ(42)) levels in cerebrospinal fluid (CSF) were markedly altered in response to a 4-week dietary intervention in normal aging and mild cognitive impairment (MCI). Here, we re-examined the data to assess whether diet-induced effects on CSF Aβ(42) were modulated by high intensity physical activity (hi-PA). Normal older adults (n = 18, mean age = 68.6 ± 7.4 y) and adults with amnestic MCI (n = 23, mean age = 68.0 ± 6.5 y) received a low saturated fat/low glycemic index (LOW) diet or a high saturated fat/high glycemic index (HIGH) diet, and CSF levels of Aβ(42), tau, and IL-8 were measured at baseline and week 4. Pre-study activity levels were assessed using a 7-d questionnaire, and weekly duration of hi-PA was quantified. At baseline, increased hi-PA in normals predicted lower CSF levels of tau (r = -0.54, p = 0.020) and IL-8 (r = -0.70, p = 0.025). Diet-induced effects on CSF Aβ(42) during the intervention study were modulated by hi-PA, and the nature of this effect differed for normals and MCI (ANOVA, p = 0.039). That is, for normal adults, increased hi-PA attenuated the effects of the HIGH diet on CSF Aβ(42) whereas in MCI, increased hi-PA potentiated the effects of the LOW diet. Our results suggest that normal adults who engage in hi-PA are less vulnerable to the pathological effects of an unhealthy diet, while in MCI, the benefit of a healthy diet on Aβ modulation is greatest when paired with hi-PA. Exercise may thus interact with diet to alter pathological processes that ultimately modify risk of Alzheimer's disease.

    A physically active lifestyle is an important contributor to individual health and well-being. The evidence linking higher physical activity levels with better levels of morbidity and mortality is well understood. Despite this, physical inactivity remains a major global risk factor for mortality and, consequently, encouraging individuals to pursue physically active lifestyles has been an integral part of public health policy in many countries. Physical activity promotion and interventions are now firmly on national health policy agendas, including policies that promote active travel such as walking and cycling. This study evaluates one such active travel initiative, the Smarter Choices, Smarter Places programme in Scotland, intended to encourage uptake of walking, cycling and the use of public transport as more active forms of travel. House to house surveys were conducted before and after the programme intervention, in May/June 2009 and 2012 (12,411 surveys in 2009 and 9542 in 2012), for the evaluation of the programme. This paper analyses the physical activity data collected, focussing on what can be inferred from the initiative with regards to adult uptake of physical activity participation and whether, for those who participated in physical activity, the initiative impacted on meeting recommended physical activity guidelines. The results suggest that the initiative impacted positively on the likelihood of physical activity participation and meeting the recommended physical activity guidelines. Individuals in the intervention areas were on average 6% more likely to meet the physical activity guidelines compared to individuals in the non intervention areas. However, the absolute prevalence of physical activity participation declined in both intervention and control areas over time. Our evaluation of this active transport initiative indicates that similar programmes may aid in contributing to achieving physical activity targets and adds to the international

    intervention programme to promote physical activity in a defined high-risk group accessible through primary care. The intervention programme is based on psychological theory and evidence; it introduces and facilitates the use of self-regulatory skills to support behaviour change and maintenance. The trial addresses a range of methodological weaknesses in the field by careful specification and quality assurance of the intervention programme, precise characterisation of participants, year-long follow-up and objective measurement of physical activity. Due to report in 2005, ProActive will provide estimates of the extent to which this approach could assist at-risk groups who could benefit from changes in behaviours affecting health, and inform future pragmatic trials.

    Although studies have looked at the effect of physical activity on obesity and other health outcomes, the causal nature of this relationship remains unclear. We fill this gap by investigating the impact of leisure-time physical activity (LTPA) and work-related physical activity (WRPA) on obesity and chronic conditions in Canadians aged 18-75 using instrumental variable and recursive bivariate probit approaches. Average local temperatures surrounding the respondents' interview month are used as a novel instrument to help identify the causal relationship between LTPA and health outcomes. We find that an active level of LTPA (i.e., walking ≥1 h/day) reduces the probability of obesity by five percentage points, which increases to 11 percentage points if also combined with some WRPA. WRPA exhibits a negative effect on the probability of obesity and chronic conditions. Copyright © 2014 John Wiley & Sons, Ltd.

    Full Text Available More than 60% of older Americans have sedentary lifestyles1 1 According to DHHS (1996. and are recommended more physical activities for health benefit. Nearby outdoor environments on residential sites may impact older inhabitants׳ physical activities there (defined as walking, gardening, yard work, and other outdoor physical activities on residential sites. This study surveyed 110 assisted-living residents in Houston, Texas, regarding their previous residential sites before moving to a retirement community and physical activities there. Twelve environmental features were studied under four categories (typology, motivators, function, and safety. Based on data availability, a subset of 57 sample sites was analyzed in Geographic Information Systems. Hierarchical linear modeling was applied to estimate physical activities as a function of the environments. Higher levels of physical activity were found to be positively related with four environmental features (transitional-areas, connecting-paths, walk-ability, and less paving.

    Working mothers experience several barriers to physical activity. If these barriers can be identified by occupational health nurses and they can partner with working mothers to reduce these perceived barriers, the health of these workers can be improved and chronic disease risk prevented. The purpose of this study was to measure the effect of self-regulatory efficacy on physical activity among working mothers and to describe specific barriers to physical activity. The Barriers Specific Self-Efficacy Scale (BARSE) and the Kaiser Physical Activity Survey (KPAS) were used to measure the variables. Self-regulatory efficacy was found to be a strong predictor of physical activity in a diverse sample of working mothers who did not meet current recommendations for physical activity. Occupational health nurses can use these findings to design programs for groups and for counseling individuals. Copyright 2011, SLACK Incorporated.

  2. Physical activity as a metabolic stressor.

    Science.gov (United States)

    Coyle, E F

    2000-08-01

    Both physical activity and diet stimulate processes that, over time, alter the morphologic composition and biochemical function of the body. Physical activity provides stimuli that promote very specific and varied adaptations according to the type, intensity, and duration of exercise performed. There is further interest in the extent to which diet or supplementation can enhance the positive stimuli. Prolonged walking at low intensity presents little metabolic, hormonal, or cardiovascular stress, and the greatest perturbation from rest appears to be from increased fat oxidation and plasma free fatty acid mobilization resulting from a combination of increased lipolysis and decreased reesterification. More intense jogging or running largely stimulates increased oxidation of glycogen and triacylglycerol, both of which are stored directly within the muscle fibers. Furthermore, these intramuscular stores of carbohydrate and fat appear to be the primary substrates for the enhanced oxidative and performance ability derived from endurance training-induced increases in muscle mitochondrial density. Weightlifting that produces fatigue in brief periods (ie, in 15-90 s and after 15 repetitive contractions) elicits a high degree of motor unit recruitment and muscle fiber stimulation. This is a remarkably potent stimulus for altering protein synthesis in muscle and increasing neuromuscular function. The metabolic stress of physical activity can be measured by substrate turnover and depletion, cardiovascular response, hormonal perturbation, accumulation of metabolites, or even the extent to which the synthesis and degradation of specific proteins are altered, either acutely or by chronic exercise training.

    The level of physical activity (PA) of pregnant women in Finland is unknown. Even more limited is our knowledge of PA of women at high risk for gestational diabetes mellitus (GDM). The women (n=54) were randomly assigned to a lifestyle intervention group (n=27) including exercise advice by a physiotherapist six times during pregnancy or to a control group (n=27) without additional exercise advice. Outcomes of the present study were required sample size, timing of counselling and change of PA. PA was retrospectively reported during 12 months before pregnancy and recorded one week monthly during pregnancy. Individualized counselling by a physiotherapist resulted in small changes of recreational PA (2.7 MET hours/week, p=0.056) up to gestational week 25 compared with the similar decreasing tendency of PA in the control group. The women decreased recreational PA after week 30. Sample size of 550 women at high risk for GDM per group would be needed for a PA study. The optimal time window for increasing PA must be earlier than in the last trimester of pregnancy. Sample size for a study to increase PA by 2.7 MET hours/week on pregnant women at high risk of GDM should be about 550 per group. Copyright © 2012 Primary Care Diabetes Europe.

    The purpose of our study was to evaluate the association between the intensity of physical activity (PA) and prevalence of cardiovascular disease (CVD) using Korean representative data. We analyzed 39 804 participant data from the Korea National Health and Nutrition Examination Survey, 2007-2013. Exposure variable was three levels of PA (low, medium, and high) in a week, and outcome variable was prevalence of CVD based on patient self-recognition and doctor's diagnosis. Complex logistic regression analysis was performed to evaluate the relationship between level of PA and CVD adjusted by body mass index, hypertension, hypercholesterolemia, diabetes mellitus, stress recognition, household income, smoking, and current drinking. The indices of association w ere estimated as crude prevalence odds ratio (POR), adjusted POR, and their 95% confidence interval (CI). All statistical analyzes were performed using complex sample analysis procedure of the SPSS version 23.0. When all variables were adjusted, only high level PA in women showed a significant association with stroke (adjusted POR by patient's self-recognition, 0.57; 95% CI, 0.32 to 0.99, adjusted POR by doctor's diagnosis, 0.55; 95% CI, 0.34 to 0.87) and CVD (adjusted POR by doctor's diagnosis, 0.68; 95% CI, 0.48 to 0.96). High level PA in women has a significant reverse association with prevalence of stroke and CVD in Korea. Further study for elucidating the mechanism will be needed.

    This study aimed to investigate longitudinal associations of objectively measured physical activity (PA) and sedentary behavior (SB) with body composition and physical fitness at a 12-month follow-up in healthy Swedish 4-yr-old children. The data from the population-based MINISTOP trial were collected between 2014 and 2016, and this study included the 138 children who were in the control group. PA and SB were assessed using the wrist-worn ActiGraph (wGT3x-BT) accelerometer during seven 24-h periods and, subsequently, defined as SB, light-intensity PA, moderate-intensity PA, vigorous-intensity PA (VPA), and moderate-to-vigorous PA (MVPA). Body composition was measured using air-displacement plethysmography and physical fitness (cardiorespiratory fitness, lower and upper muscular strength as well as motor fitness) by the PREFIT fitness battery. Linear regression and isotemporal substitution models were applied. Greater VPA and MVPA at the age of 4.5 yr were associated with higher fat-free mass index (FFMI) at 5.5 yr (P fitness, lower body muscular strength, and motor fitness at 12-month follow-up (P = 0.001 to P = 0.031). Substituting 5 min·d of SB, light-intensity PA, or moderate-intensity PA for VPA at the age of 4.5 yr were associated with higher FFMI, and with greater upper and lower muscular strength at 12-month follow-up (P fitness at 12-month follow-up. Our results indicate that promoting high-intensity PA at young ages may have long-term beneficial effects on childhood body composition and physical fitness, in particular muscular strength.

    This 4-yr longitudinal study examined the different roles of perceived stress in the association between older adults’ physical activities and physical health. We hypothesized that physical activities would exert beneficial effects on physical health by preventing chronically high levels of perceived stress. Design and Measures We assessed baseline levels of physical activities and repeated measures of perceived stress and physical symptoms in three waves of data from a sample of 157 older adults. Results Among participants with high (but not low) baseline levels of perceived stress, physical activity predicted a 2-yr reduction of perceived stress and a 4-yr prevention of physical health symptoms. Moreover, the interaction effect on 4-yr changes in physical symptoms was mediated by 2-yr changes in perceived stress. Conclusions Physical health benefits of physical activity are particularly pronounced among older adults who perceive high levels of stress, and this effect is mediated by a prevention of chronically high perceptions of stress.

    2014-06-01

    The main purpose of this study was to evaluate the differences in adolescents´ objective physical activity levels and perceived effort in physical education, school recess, and extra-curricular organized sport by motivational profiles in physical education. A sample of 102 students 11-16 yr. old completed a self-report questionnaire assessing self-determined motivation toward physical education. Subsequently, students' objective physical activity levels (steps/min., METs, and moderate-to-vigorous physical activity) and perceived effort were evaluated for each situation. Cluster analysis identified a two-cluster structure: "Moderate motivation toward physical education profile" and "High motivation toward physical education profile." Adolescents in the second cluster had higher physical activity and perceived effort values than adolescents in the first cluster, except for METs and moderate-to-vigorous physical activity in extra-curricular sport. These results support the importance of physical education teachers who should promote self-determined motivation toward physical education so that students can reach the recommended physical activity levels.

    Multiple sclerosis is a degenerative neurological disease that affects 2.1 million people worldwide. There is no cure, but an expanding body of research supports the positive impact of physical activity and suggests physical activity has benefits for the individual's psychological and physical well-being. Using Self-Determination Theory as a framework, mixed methods with a focus on qualitative interviews were used to explore physical activity motivation and benefits with a sample of highly active people with multiple sclerosis (n = 15). Disability level ranged from not disabled to wheelchair bound with the majority of participants reporting minimal impact from multiple sclerosis. Survey data were collected using a number of open-ended questions along with measures of self-efficacy, self-determined motivation, physical activity, and quality of life. Additionally, eight individuals participated in semistructured telephone interviews focused on (a) motivation and strategies used to maintain physical activity and (b) the benefits and impact of physical activity in their lives. The main findings were consistent with Self-Determination Theory; participants described feelings of accomplishment and competence in both their physical activity and daily life, as well as a sense of independence and autonomy. Similarly, all participants cited benefits, and the main themes were enhanced satisfaction with life and an overall positive outlook on life. Results provide insight into the role of physical activity in a highly active sample and have implications for professionals working in physical activity settings with the multiple sclerosis population. Interventions aimed at increasing long-term physical activity adherence should focus on increasing autonomy and competence for physical activity in the individual and promoting potential increased quality of life outcomes from physical activity participation.

Cancer patients as a group are at risk for diseases and conditions related to lack of physical activity. In persons with cancer, exercise has been shown to improve fitness and physical functioning, reduce fatigue, and modestly decrease weight and body fat. The effects of physical activity on prognosis, however, are unknown. In persons without cancer, exercise has beneficial effects on the cardiovascular and endocrine systems, reducing risk of cardiovascular disease, cerebrovascular disease, and diabetes. Increased physical activity reduces risk for several common cancers, which is relevant to cancer survivors who are at increased risk for new primary cancers. Additional benefits of physical activity include improvements in fitness, muscular-skeletal problems including arthritis symptoms, immune system function, cognition and sleep. Risks of increased physical activity in cancer patients and survivors have not been defined, but could be expected to include musculo-skeletal injuries, and a small increased risk in sudden death with vigorous exercise and serious accidents with some sports. The effect of physical activity on survival from cancer is unknown, but physical activity might improve prognosis through beneficial effect on cancer biomarkers and energy balance, as well as decreasing risk for cardiovascular disease, an important cause of death for many cancer survivors. The long-term benefits and risks of physical activity in cancer patients and survivors are unknown. Nevertheless, increasing physical activity is probably beneficial and safe in the majority of cancer survivors.

    A growing body of literature indicates that physical activity can have beneficial effects on mental health. However, previous research has mainly focussed on clinical populations, and little is known about the psychological effects of physical activity in those without clinically defined disorders. The present study investigates the association between physical activity and mental health in an undergraduate university population based in the United Kingdom. One hundred students completed questionnaires measuring their levels of anxiety and depression using the Hospital Anxiety and Depression Scale (HADS) and their physical activity regime using the Physical Activity Questionnaire (PAQ). Significant differences were observed between the low, medium and high exercise groups on the mental health scales, indicating better mental health for those who engage in more exercise. Engagement in physical activity can be an important contributory factor in the mental health of undergraduate students.

    Physical inactivity is an important risk factor for chronic diseases in Western societies. To determine the sociodemographic and motivational factors associated with physical activity in college students. The International Physical Activity Questionnaire (IPAQ) -short form- and the "motives for physical activities measure-revised" (MPAM-R) questionnaire were applied to 900 university students aged 20 ± 3 years (60% women). The frequency, level and motivations for engaging in physical activity and associated demographic factors were analyzed. Twenty two percent of students were classified as having a high level of physical activity, 54.8% had a low level and 13.9% were considered inactive. According to MET consumption, 68.9% of students are inactive and only 16.8% of students classified as very active. Ninety two percent of active students performed physical activity for health reasons. A significant association between gender and social motivation was observed. A high prevalence of physical inactivity was found in these students. Males showed higher levels of physical activity than females.

    Physical activity (PA) participation has been shown to be helpful in improving physical and mental well-being among cancer survivors. The purpose of this chapter is to review the literature on the determinants of physical activity motivation and behavior among cancer survivors. Using theories of behavior change, researchers have sought to identify the correlates of motivation that predict the participation in regular physical activity in observational studies, while intervention studies have focused on manipulating those factors to support the initiation of physical activity. The majority of this work has been conducted with breast cancer survivors, and there is an interest in expanding this work to survivors of others cancers (e.g., prostate, lung, and colorectal cancer). Results suggest that constructs from the Theory of Planned Behavior (TPB), Transtheoretical Model (TTM), and Social Cognitive Theory (SCT) are associated with greater motivation for physical activity, and some of these constructs have been used in interventions to promote physical activity adoption. There is scope for understanding the determinants of physical activity adoption in various cancer survivor populations. Much more needs to done to identify the determinants of maintenance of physical activity.

    Full Text Available Ethnic minority children living in high poverty neighborhoods are at high risk of having insufficient physical activity (PA during school days and, thus, the importance of school as a place to facilitate PA in these underserved children has been largely emphasized. This study examined the levels and patterns of PA in minority children, with particular focus on the relative contributions of regular physical education (PE and school-based afterschool PA program in promoting moderate- and vigorous-intensity PA (MVPA during school days. PA data were repeatedly measured using a Polar Active accelerometer across multiple school days (M = 5.3 days per child, from seventy-five ethnic minority children attending a Title I public elementary school in a high-poverty neighborhood in the US. The minutes and percentage of MVPA accumulated during school, PE, and afterschool PA program were compared to the current recommendations (≥30-min of MVPA during school hours; and ≥50% of MVPA during PE or afterschool PA program as well as by the demographic characteristics including sex, grade, ethnicity, and weight status using a general linear mixed model that accounts for repeated observations. On average, children spent 41.6 mins (SE = 1.8 of MVPA during school hours and of those, 14.1 mins (SE = 0.6 were contributed during PE. The average proportion of time spent in MVPA during PE was 31.3% (SE = 1.3, which was significantly lower than the recommendation (≥50% of MVPA, whereas 54.2% (SE = 1.2 of time in afterschool PA program were spent in MVPA. The percentage of monitoring days meeting current recommendations were 69.5% (SE = 0.03, 20.8% (SE = 0.02, and 59.6% (SE = 0.03 for during school, PE, and afterschool PA program, respectively. Our findings highlighted that school-based afterschool PA, in addition to regular PE classes, could be of great benefit to promote PA in minority children during school days. Further research and practice are still needed to

    Full Text Available The purpose of this study was to analyze motivational profiles based on the self-determination theory (Deci and Ryan, 2000 and how these profiles are related to physical education students' enjoyment, state anxiety, and physical activity. The participants, 429 sixth grade students (girls = 216; boys = 213 completed SMS, Sport Enjoyment Scale, PESAS, and Physical Activity Scale. Cluster analyses identified two motivational profiles: 1 the "High motivation profile", in which the students had high intrinsic and extrinsic motivation, and low levels of amotivation, and 2 the "Low motivation profile", in which the students had low intrinsic and extrinsic motivation, and low levels of amotivation. The students in the first cluster enjoyed physical education more and were physically more active. The results revealed that students may be motivated towards physical education lessons both intrinsically and extrinsically, and still experience enjoyment in physical education.

    The majority of youth are not meeting the US Department of Health and Human Services physical activity guidelines. Dance is a popular activity, particularly for girls, and has the potential to increase physical activity for many youth. This study investigated physical activity of children and adolescents in 7 dance types: ballet, hip-hop, jazz, Latin-flamenco, Latin-salsa/ballet folklorico, partnered, and tap. Data were collected in 17 private studios and 4 community centers in San Diego, California. A total of 264 girls from 66 classes participated (n =154 children; n = 110 adolescents). Physical activity was measured with accelerometers, and activity levels during class were calculated. Participants recorded an average of 17.2 ± 8.9 minutes of moderate-to-vigorous physical activity (36% of class), but this varied by age and dance type. For children, dance type differences were observed with percent of class in moderate-to-vigorous physical activity ranging from 13.6% (Latin-flamenco) to 57% (hip-hop). For adolescents, there were no differences across dance types. Children were more active than adolescents in all types except ballet. Children and adolescents were more active in private compared with community center classes. Overall, physical activity in youth dance classes was low; 8% of children and 6% of adolescents met the Centers for Disease Control and Prevention 30-minute guideline for after-school physical activity during dance. To increase physical activity in dance classes, teaching methods could be employed to increase activity in all types, or emphasis could be placed on greater participation in more active dance types.

    The aim of the study was to investigate if adolescents' perceived physical competence towards physical activity (PA), and autonomous motivation and enjoyment in physical education (PE) during early adolescence can predict amount and intensity of self-reported physical activity six years later. This study utilized a 6-year longitudinal data set collected within Finnish school settings. Students responded to questionnaires measuring their perceived physical competence towards physical activity, and autonomous motivation and enjoyment in PE during their first year at middle school (Grade 7), and their PA engagement during their last year in high school (Grade 12). A sample of 333 students (200 girls, 133 boys; M age=12.41, years, SD=.27) participated in the study. Perceived physical competence in physical activity was assessed by the sport competence dimension of the Physical Self-Perception Profile, autonomous motivation in PE was assessed by the Sport Motivation Scale and enjoyment in PE by the Sport Enjoyment Scale. Students' self-reported metabolic equivalent (MET) and PA intensity (light [LPA], moderate [MPA], vigorous [VPA]) was calculated from the short form of International Physical Activity Questionnaire. Perceived physical competence towards physical activity significantly predicted total METs (β=.28), MPA (β=.18) and VPA (β=.29) six years later. Autonomous motivation and enjoyment in PE at Grade 7, however, were not significant predictors of later PA. The results of this study support the proposition that self-perception of an individual's abilities arising from interactions with the environment related to PA during early puberty has an influential effect on later PA behaviour.

    2011-05-01

    The purpose of this study was to examine adolescents' physical self-perceptions and their associations with physical activity using a longitudinal perspective. Utilizing data from the Physical Activity in Scottish Schoolchildren (PASS) study, changes in exercise self-efficacy, perceived competence, global self-esteem and physical self-worth were assessed among a sample of 641 Scottish adolescents from age 11-15 years. Girls reported lower levels of perceived competence, self-esteem and physical self-worth than boys at each age. Furthermore, girls' physical self-perceptions decreased markedly over time. Among boys, only perceived competence decreased, while global self-esteem increased. Baseline physical activity was a significant predictor of later activity levels for both genders. Findings demonstrate the importance of physical self-perceptions in relation to physical activity behavior among adolescents. Among older boys, high perceived competence increased the odds of being active by 3.8 times. Among older girls, high exercise self-efficacy increased the odds of being active by 5.2 times. There is a need for early interventions which promote increased physical literacy and confidence, particularly among girls.

    When students make the transition from high school to college or university, their physical activity (PA) levels decrease strongly. Consequently, it is of crucial importance to identify the determinants of this decline in PA. The study aims were to (1) examine changes in psychosocial factors in students during the transition from high school to college/university, (2) examine if changes in psychosocial factors and residency can predict changes in PA, and (3) investigate the moderating effects of residency on the relationship between changes in psychosocial factors and changes in PA. Between March 2008 and October 2010, 291 Flemish students participated in a longitudinal study, with baseline measurements during the final year of high school and follow-up measurements at the start of second year of college/university. At both time points, participants completed a questionnaire assessing demographics, active transportation, leisure-time sports, psychosocial variables, and residency. Repeated measures MANOVA analyses and multiple moderated hierarchic regression analyses were conducted. Modeling, self-efficacy, competition-related benefits, and health-related, external and social barriers decreased, while health-related benefits and time-related barriers increased from baseline to follow-up. Decreases in modeling and time-related barriers were associated with a decrease in active transportation (adjusted R(2) = 3.2%); residency, decreases in self-efficacy, competition-related benefits, and increases in health- and time-related barriers predicted a decrease in leisure-time sports (adjusted R(2) = 29.3%). Residency only moderated two associations between psychosocial factors and changes in PA. Residency and changes in psychosocial factors were mainly important to explain the decrease in leisure-time sports. Other factors such as distance to college/university are likely more important to explain the decrease in active transportation; these are worth exploring in

    The World Health Organization and the World Economic Forum have recommended further research to strengthen current knowledge of workplace health programmes, particularly on effectiveness and using simple instruments. A pedometer is one such simple instrument that can be incorporated in workplace interventions. To assess the effectiveness of pedometer interventions in the workplace for increasing physical activity and improving subsequent health outcomes. Electronic searches of the Cochrane Central Register of Controlled Trials (671 potential papers), MEDLINE (1001), Embase (965), CINAHL (1262), OSH UPDATE databases (75) and Web of Science (1154) from the earliest record to between 30th January and 6th February 2012 yielded 3248 unique records. Reference lists of articles yielded an additional 34 papers. Contact with individuals and organisations did not produce any further records. We included individual and cluster-randomised controlled trials of workplace health promotion interventions with a pedometer component in employed adults. The primary outcome was physical activity and was part of the eligibility criteria. We considered subsequent health outcomes, including adverse effects, as secondary outcomes. Two review authors undertook the screening of titles and abstracts and the full-text papers independently. Two review authors (RFP and MC) independently completed data extraction and risk of bias assessment. We contacted authors to obtain additional data and clarification. We found four relevant studies providing data for 1809 employees, 60% of whom were allocated to the intervention group. All studies assessed outcomes immediately after the intervention had finished and the intervention duration varied between three to six months. All studies had usual treatment control conditions; however one study's usual treatment was an alternative physical activity programme while the other three had minimally active controls. In general, there was high risk of bias mainly

  6. Multimorbidity, cognitive function, and physical activity.

    Loprinzi, Paul D

    2016-02-01

    Previous research demonstrates that both physical activity and multimorbidity are associated with cognitive function. However, the extent to which physical activity may moderate the relationship between multimorbidity and cognitive function has not been thoroughly evaluated. Data from the 1999-2002 NHANES were used (60+ years; N = 2157). A multimorbidity index variable was created based on physician diagnosis of a multitude of chronic diseases. Physical activity was self-reported and cognitive function was evaluated from the digit symbol substitution test. Multimorbidity was inversely associated with cognitive function for the unadjusted and adjusted models. However, generally, multimorbidity was no longer associated with cognitive function for the majority of older adults who achieved the minimum recommended physical activity level (≥2000 MET-min-month), as issued by the United States Department of Health and Human Services. In this national sample of older adults, there was some evidence to suggest that physical activity moderates the relationship between multimorbidity and cognitive function.

    Kumar, Bhavesh; Robinson, Rebecca; Till, Simon

    2015-06-01

    Adolescence represents a critical period of development during which personal lifestyle choices and behaviour patterns establish, including the choice to be physically active. Physical inactivity, sedentary behaviour and low cardiorespiratory fitness are strong risk factors for the development of chronic diseases with resulting morbidity and mortality, as well as economic burden to wider society from health and social care provision, and reduced occupational productivity. Worrying trends in adverse physical activity behaviours necessitate urgent and concerted action. Healthcare professionals caring for adolescents and young adults are ideally placed and suited to deliver powerful messages promoting physical activity and behaviour change. Every encounter represents an opportunity to ask about physical activity, provide advice, or signpost to appropriate pathways or opportunities. Key initial targets include getting everyone to reduce their sedentary behaviour and be more active, with even a little being more beneficial than none at all. © Royal College of Physicians 2015.

    The department of Physics and Astronomy with the department of Science Education at California State University, Long Beach hosted summer program of ``Phun Physics 4 Phemales (PP4P)'' during summer 2012 and summer 2013 with the support from APS public outreach program. PP4P summer camp was hosted along with a two-week summer science camp, Young Scientists Camp, which has been institutionalized for the last 14 years since 1999. More than 2,500 3rd -8th grade students and 250 teachers have participated in the program. PP4P program provided the tools and support that female high school students need to pursue careers in physics and/or science, technology, engineering and math (STEM) field. This girls-only camp created connections among the girls and built confidence. In addition PP4P program introduced students to key principles in physics by a hands-on lab environment and demonstrated the real-world social impact of physics. In summer 2012, high school girls worked on physics experimental project on electronics and in summer 2013 they worked on the mechanics. I would share our experience in this program and the impact on the female high school students.

    Little research is available concerning physical activity and its determinants in people with chronic neck pain. To explore the relation between kinesiophobia and physical activity and gender effect on these relations in people with chronic neck pain. Ninety-nine subjects (34 men and 65 women) with chronic neck pain were participated in the study. Pain intensity was assessed with Visual Analog Scale and kinesiophobia degree was determined by using Tampa Scale of Kinesiophobia. Level of physical activity was assessed with short form of the International Physical Activity Questionnaire. There was no statistically correlation between neck pain intensity and kinesiophobia degree (p= 0.246, r= 0.123) and physical activity level (p= 0.432, r= -0.083). It was also found that kinesiophobia degree was not correlated to physical activity level (p= 0.148, r= -0.153). There was a negative correlation between kinesiophobia degree and physical activity level only for women, not for men (p= 0.011, r= -0.318). Our results showed that although people with chronic neck pain reported higher pain intensity and fear of movement, pain intensity and kinesiophobia degree did not associate to their physical activity levels. It can be speculated that high kinesiophobia degrees cause low physical activity levels for women, but not for men.

    Physical activity is usually done in specific types of places, referred to as physical activity environments. These often include parks, trails, fitness centers, schools, and streets. In recent years, scientific interest has increased notably in measuring physical activity environments. The present paper provides an historical overview of the contributions of the health, planning, and leisure studies fields to the development of contemporary measures. The emphasis is on attributes of the built environment that can be affected by policies to contribute to the promotion of physical activity. Researchers from health fields assessed a wide variety of built environment variables expected to be related to recreational physical activity. Settings of interest were schools, workplaces, and recreation facilities, and most early measures used direct observation methods with demonstrated inter-observer reliability. Investigators from the city planning field evaluated aspects of community design expected to be related to people's ability to walk from homes to destinations. GIS was used to assess walkability defined by the 3Ds of residential density, land-use diversity, and pedestrian-oriented designs. Evaluating measures for reliability or validity was rarely done in the planning-related fields. Researchers in the leisure studies and recreation fields studied mainly people's use of leisure time rather than physical characteristics of parks and other recreation facilities. Although few measures of physical activity environments were developed, measures of aesthetic qualities are available. Each of these fields made unique contributions to the contemporary methods used to assess physical activity environments.

    To test the independent and interactive associations of physical activity (PA) and screen time (ST) with self-reported mental health and sleep quality among Chinese college students. Data were collected in October, 2013. The gender, age, residential background, body mass index (BMI), perceived family economy and perceived study burden were obtained from a total of 4747 college students (41.6% males and 58.4% females). The outcomes were self-reported PA status, ST, anxiety, depression, psychopathological symptoms and sleep quality. Analyses were conducted with logistic regression models. Overall, 16.3%, 15.9% and 17.3% of the students had psychological problems, such as anxiety, depression and psychopathological symptoms, respectively. The prevalence of poor sleep quality was 9.8%. High ST was significantly positively associated with anxiety (OR=1.38, 95%CI: 1.15-1.65), depression (OR=1.76, 95%CI: 1.47-2.09), psychopathological symptoms (OR=1.69, 95%CI: 1.43-2.01) and poor sleep quality (OR=1.32, 95%CI: 1.06-1.65). High PA was insignificantly negatively associated with anxiety, depression, psychopathological symptoms and poor sleep. Low PA and high ST were independently and interactively associated with increased risks of mental health problems and poor sleep quality (p<0.05 for all). Interventions are needed to reduce ST and increase PA in the lifestyles of young people. Future research should develop and measure the impacts of interventions and their potential consequences on sleep, health, and well being.

    The hadron collider group is studying proton-antiproton interactions at the world`s highest collision energy 2 TeV. Data-taking with the D0 detector is in progress at Fermilab and the authors have begun the search for the top quark. S. Wimpenny is coordinating the effort to detect t{bar t} decaying to two leptons, the most readily identifiable channel. At UC Riverside design and testing for a silicon tracker for the D0 upgrade is in progress; a parallel development for the SDC detector at SSC is also underway. The major group effort of the lepton group has been devoted to the OPAL experiment at LEP. They will continue to focus on data-taking to improve the quality and quantity of their data sample. A large number of papers have been published based on approximately 500,000 events taken so far. The authors will concentrate on physics analysis which provides stringent tests of the Standard Model. The authors are continuing participation in the RD5 experiment at the SPS to study muon triggering and tracking. The results of this experiment will provide critical input for the design of the Compact Muon Solenoid experiment being proposed for the LHC. The theory group has been working on problems concerning the possible vilation of e-{mu}-{tau} universality, effective Lagrangians, neutrino physics, as well as quark and lepton mass matrices.

    Time perspective is a cultural behavioral concept that reflects individuals' orientations or attitudes toward the past, present, or future. Individuals' time perspectives influence their choices regarding daily activities. Time perspective is an important consideration when teaching adolescents about the importance of being physically active. However, little is known about the relationship between time perspective and physical activity among adolescents. The purpose of this study was to determine the time perspective of central Appalachian adolescents and explore the relationship between time perspective and physical activity. This study was guided by The theory of planned behavior (TPB). One hundred and ninety-three students completed surveys to examine time perspective and physical activity behaviors. Data were collected in one school. Results of this study can inform school nurses and high school guidance counselors about the importance of promoting a future-oriented time perspective to improve physical activity and educational outcomes.

  6. Physically active lifestyle does not decrease the risk of fattening.

    Directory of Open Access Journals (Sweden)

    Klaas R Westerterp

    Full Text Available BACKGROUND: Increasing age is associated with declining physical activity and a gain in fat mass. The objective was to observe the consequence of the age-associated reduction in physical activity for the maintenance of energy balance as reflected in the fat store of the body. METHODOLOGY/PRINCIPAL FINDINGS: Young adults were observed over an average time interval of more than 10 years. Physical activity was measured over two-week periods with doubly labeled water and doubly labeled water validated triaxial accelerometers, and body fat gain was measured with isotope dilution. There was a significant association between the change in physical activity and the change in body fat, where a high initial activity level was predictive for a higher fat gain. CONCLUSION/SIGNIFICANCE: The change from a physically active to a more sedentary routine does not induce an equivalent reduction of energy intake and requires cognitive restriction to maintain energy balance.

    (1) To study the relation of physical activity (PA) to high-density lipoprotein cholesterol (HDL-C) and (2) to investigate if the strength of these associations holds after adjustments for sex, age, and other key correlates. This study included 550 older adults from Amazonas. HDL-C was derived from fasting blood samples. PA at sport and leisure, smoking, alcohol consumption, and socioeconomic status (SES) were interviewed. Waist circumference (WACI) was assessed. HDL-C was positively related to PA sport, PA leisure, and SES (0.22≤r≤0.34; p≤0.001) and negatively related to smoking and WACI (r≤-0.10; p<0.05). Controlling for sex and age did not affect these relationships. Hierarchical multiple regression analyses showed that the relation of HDL-C to PA sport and leisure remained significant when controlling for all other investigated correlates (0.14≤β≤0.24; p≤0.001). In order to prevent low HDL-C in older adults, promoting PA seems to be an important additional component besides common recommendations concerning weight reduction. Copyright © 2017 Elsevier B.V.

    The finding that during recovery from high intensity exercise, rats have the capacity to replenish their muscle glycogen stores even in the absence of food intake has provided us with an experimental model of choice to explore further this process. Our objective here is to share those questions arising from research carried out by others and ourselves on rats and humans that are likely to be of interest to comparative biochemists/physiologists. On the basis of our findings and those of others, it is proposed that across vertebrate species: (1). the capacity of muscles to replenish their glycogen stores from endogenous carbon sources is dependent on the type of physical activity and animal species; (2). lactate and amino acids are the major endogenous carbon sources mobilized for the resynthesis of muscle glycogen during recovery from exercise, their relative contributions depending on the duration of recovery and type of exercise; (3). the relative contributions of lactate glyconeogenesis and hepatic/renal gluconeogenesis to muscle glycogen synthesis is species- and muscle fiber-dependent; and (4). glycogen synthase and phosphorylase play an important role in the control of the rate of glycogen synthesis post-exercise, with the role of glucose transport being species-dependent.

    2009-02-01

    In this study, we examined the influence of maturation on social physique anxiety, the relationship between social physique anxiety and current and future physical activity levels, and the influence of motives for physical activity on this relationship in early adolescent girls (n=162; mean age = 11.8 +/- 0.3 years). Participants completed the Pubertal Development Scale, the modified Social Physique Anxiety Scale, and the Motives for Physical Activity Scale at baseline and the Physical Activity Questionnaire for Older Children at baseline and 6 months later. The girls became less active across the 6 months and girls in the early stages of maturation had significantly lower social physique anxiety than the girls in the middle and late stages of maturation. Social physique anxiety was not related to current or future physical activity in the sample as a whole. Cluster analysis identified four groups with different motive profiles and the High Appearance and Fitness group demonstrated a moderate negative relationship between social physique anxiety and physical activity at phase 1, whereas the other groups did not. These findings indicate that social physique anxiety may increase with maturation and the relationship between social physique anxiety and physical activity is dependent on reasons for being active. For girls who are motivated to be active primarily by body-related reasons, social physique anxiety is likely to lead to lower levels of physical activity.

    The aim of this study was to verify the effects of programmed and self-selected physical activities on the physical fitness of adolescents. High school adolescents, aged between 15 and 17 years, were divided into two experimental groups: a) a self-selected physical activity group (PAS) with 55 students (aged 15.7 ± 0.7 years), who performed physical activities with self-selected rhythm at the following sports: basketball, volleyball, handball, futsal and swimming; and b) a physical fitness training group (PFT) with 53 students (aged 16.0 ± 0.7 years), who performed programmed physical fitness exercises. Both types of activity were developed during 60 min classes. To assess physical fitness the PROESP-BR protocol was used. The statistical analysis was performed by repeated measures ANOVA. The measurements of pre and post-tests showed significantly different values after PFT in: 9 minute running test, medicine ball throw, horizontal jump, abdominal endurance, running speed and flexibility. After PAS differences were detected in abdominal endurance, agility, running speed and flexibility. The intervention with programmed physical activity promoted more changes in the physical abilities; however, in the self-selected program, agility was improved probably because of the practice of sports. Therefore, physical education teachers can use PFT to improve cardiorespiratory fitness and power of lower and upper limbs and PAS to improve agility of high school adolescents.

    Full Text Available The aim of this study was to verify the effects of programmed and self-selected physical activities on the physical fitness of adolescents. High school adolescents, aged between 15 and 17 years, were divided into two experimental groups: a a self-selected physical activity group (PAS with 55 students (aged 15.7 ± 0.7 years, who performed physical activities with self-selected rhythm at the following sports: basketball, volleyball, handball, futsal and swimming; and b a physical fitness training group (PFT with 53 students (aged 16.0 ± 0.7 years, who performed programmed physical fitness exercises. Both types of activity were developed during 60 min classes. To assess physical fitness the PROESP-BR protocol was used. The statistical analysis was performed by repeated measures ANOVA. The measurements of pre and post-tests showed significantly different values after PFT in: 9 minute running test, medicine ball throw, horizontal jump, abdominal endurance, running speed and flexibility. After PAS differences were detected in abdominal endurance, agility, running speed and flexibility. The intervention with programmed physical activity promoted more changes in the physical abilities; however, in the self-selected program, agility was improved probably because of the practice of sports. Therefore, physical education teachers can use PFT to improve cardiorespiratory fitness and power of lower and upper limbs and PAS to improve agility of high school adolescents.

    The aim of the study was to objectively determine whether the Nutrition and Physical Activity Self-Assessment for Child Care (NAP SACC) program improved physical activity levels during the school day. The study compared the physical activity levels of subjects from 26 daycare centers, randomized into treatment (N=13) and control (N=13) groups. The subjects were 3 to 5 year olds (N=209, 104 males and 105 females; age [years]=3.85±0.8 [mean±standard deviation]), and accelerometry was used to determine the subjects' physical activity levels. Accelerometers were attached to each subject for 2 days before and immediately after a 6-month intervention. Height, mass, and waist were also measured. Regression analyses indicated that the treatment group demonstrated significant increases in moderate and vigorous physical activity, as compared to the control group (F(1, 207)=6.3, pdaycare facilities resulted in significant increases in objectively measured physical activity levels, compared to the control group, demonstrating physical activity improvement in the treatment daycare centers.

    We present evidence of feed-forward loop relationships and positive association between physical activity and performance levels, which are components of frailty, using measures from 431 high functioning women initially aged 70-79 years followed over 7 visits. Physical activity levels were assessed using a questionnaire. Grip strength was measured using a handheld dynamometer and usual walking speed was measured over 4-m. The results suggest that a reduction in physical activity would not only degrade physical performance, but it would further reduce physical activity through declines in physical performance. As both physical activity and physical performance impact frailty, improvement of physical activity could help reduce frailty directly as well as indirectly via improved physical performance. Our findings support a priori hypothesis that feed-forward loops are present in the phenotype of frailty, which is due to dysregulated energetics. A methodologically broader implication is that we introduce modeling and analysis of feed-forward loop data here. The feed-forward loop, as we define it, is different from the concept of feedback loops used in biochemical systems. Generalizing our model of two-variable feed-forward loop, three, four or multivariable feed-forward loop can be applied to other biological systems. Copyright © 2014 Elsevier Ireland Ltd.
