Abstract

The promotion of cardiorespiratory fitness through increased physical activity has become a national public health objective for both adults and children. Based on numerous small-scale studies it appears that children are highly fit but the population distribution is unknown due to the lack of rigorous population studies. Very little is known about the extent of children's physical activity; the available evidence does not support the hypothesis that children obtain sufficient activity to explain their generally high levels of fitness. Due to the lack of evidence of substantial carry-over effects of youth fitness to adult health and the likelihood of children's resistance to vigorous fitness routines, there is little reason to recommend an aerobic training focus in physical education. A focus on enjoyable moderate to vigorous physical activity (MVPA) with carry-over value to adulthood is recommended. Physical education is an important vehicle for promoting physical activity by children; it appears, however, that children may obtain little MVPA during physical education class.  相似文献

Abstract

Physical activity in adolescents is an important public health issue. Regular participation in physical activity is associated with various health benefits. However, problems with motivational adherence to physical activity have been documented. The transtheoretical model is a model of behaviour change. This model, which consists of stages of change, self-efficacy, decisional balance, and processes of change, has not been extensively investigated in youth. In addition, the health-enhancing physical activity concept has rarely been applied in this context.

A cross-sectional design was used. A random sample of seven junior high schools from Bremen (Germany) resulted in a sample of 588 adolescents (50.5% males, mean age=15.0 years, s=0.67). Respondents completed a self-administered questionnaire assessing stages of change, self-efficacy, decisional balance, and processes of change. Univariate analyses of variance were used to identify which constructs differed significantly across the stages of change. Discriminant analysis was used to determine which variables best discriminate the stages.

Distribution of the sample across the stages was: precontemplation, n=175 (29.8%); contemplation, n=135 (22.0%); preparation, n=63 (10.7%); action, n=20 (3.4%); and maintenance, n=195 (33.2%). Significant effects of stages of change were found for self-efficacy, pros, and seven of the ten processes of change. In general, scores of these constructs increased across the stages. Cons did not differ significantly across the stages.

The results provide support for some of the assumptions of the transtheoretical model in a German sample of adolescents. Some of our findings raise questions about the usefulness of five discrete stages. From a public health viewpoint, tailored interventions based on motivational readiness to change would be fruitful, but further research is warranted.  相似文献

Abstract

Regular exercise and lifestyle physical activity are often used interchangeably or combined in physical activity messaging based on evidence for their relatively equivalent health outcomes. However, differences between their motivational correlates are relatively unexplored. The purpose of this study was to compare the motives towards lifestyle physical activity and exercise and their relationship with behaviour using the Theory of Planned Behaviour (TPB). The participants were a sample of undergraduate students (n=150) who completed measures of the TPB framed in terms of exercise and lifestyle physical activity and self-reported physical activity measures with similar framing. Results identified marked differences between the instrumental attitudes towards the two activities showing instrumental attitudes towards exercise to be higher (P<0.01; d=0.68). Most importantly, exercise had larger TPB–behaviour correlations (P<0.01; q=0.15–0.20) compared with lifestyle physical activity, but follow-up analyses by intensity (strenuous, moderate, mild) showed that these differences were only present at strenuous intensity. Our results suggest that the correlates for the two types of physical activity may differ. Although more research is necessary, this may affect the efficacy of promotion campaigns that do not tailor content exclusively for either exercise or lifestyle physical activity.  相似文献

PurposeThe study was to examine county-level associations of physical activity with coronavirus disease 2019 (COVID-19) cases and deaths, per 100,000 county residents.MethodsData were collected from publicly available data sources for 3142 counties and equivalents, including the District of Columbia. Subjective health ratings, percentage uninsured, percentage unemployed, median household income, percentage female residents, percentage White residents, percentage of residents 65 years of age or older, and rural designation served as controls.ResultsThe two-level random intercept regression showed that physical activity rates at the county level were statistically and negatively associated with COVID-19 cases and deaths. Additional analyses showed that physical activity rates moderated the relationship between cases and deaths, such that the relationship was strongest when physical activity rates were low.ConclusionThe results presented here offer empirical evidence of the benefits of county-level physical activity during a pandemic. Implications for public health and physical activity provision are discussed.  相似文献

BackgroundThe purpose of motivating students is to enhance their learning achievement. The expectancy-value theory (EVT) has demonstrated its efficacy in motivating students in classrooms and in gymnasia. Understanding student motivation in physical education is needed. This meta-analysis review aimed to reveal the determinants and functions of EVT by evaluating the evidence in physical education research.MethodsWe followed the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines to identify and meta-analyze the current research literature published from January 2010 to December 2020 by generating and analyzing the effect sizes from the studies.ResultsA total of 31 studies were included. The results show that social support, motivation of teachers and peers, and positive class climate can predict student EVT motivation. EVT motivation predicts student learning behaviors, situational interests, fitness performance, health behavior function, out-of-school physical activity, and physical skill development.ConclusionEVT motivation could facilitate learning behaviors and situational interest development in the gymnasium. It might lead to fitness enhancement, health behavior change, out-of-school physical activity participation, and physical skill development. Fostering a learning environment with a mastery-centered and/or student autonomy approach where students perceived success and the task values can enhance and maximize student EVT motivation and learning achievement.  相似文献

Sedentary behaviour (SB) has recently emerged as an independent risk factor for different health outcomes. Older adults accumulate long time in SB. Understanding the role that SB plays on health is crucial for a successful aging. This short systematic review summarizes the current evidence related to the effects of objectively measured SB on frailty, physical performance and mortality in adults ≥60?years old. The literature search produced 271 records for physical performance (n?=?119), frailty (n?=?31), and mortality (n?=?121). Finally, only 13 articles fulfilled the inclusion criteria and were included in this review. All articles but one included in the physical performance section (n?=?9) showed a negative association between longer time spent in SB and physical performance. A significant association of SB with higher odds of frailty was found, however this association disappeared after adjusting for cognitive status. Lastly, two of the three included studies showed positive associations between SB and mortality, but this effect decreased or even disappeared in the more adjusted models. In conclusion, there is consistency that SB is negatively associated with physical performance. However, the relationship between objectively measured SB and frailty incidence and mortality rates remains unclear and deserves further research. The use of homogenous criteria to assess SB and the inclusion of more robust research designs will help clarifying the independent effects that SB could have on physical performance, frailty, and mortality. This will ultimately help designing more efficient and comprehensive physical activity guidelines for older adults.  相似文献

Objectives: This study’s aims were to describe the development of physical activity, physical fitness (PF), subjective (physical complaints (PC)) and objective (Body mass index (BMI)) health measures and to examine the relationship between the development trajectories. In addition, the study also aimed to assess the influence of sociodemographic determinants (age, sex, socioeconomic status (SES)) in German adults over a period of 18 years. Methods: The longitudinal study population comprises of 721 men and women, aged 33–76 years over the study period. There was self-report of physical activity and PC and testing of physical fitness and BMI in each study year (1992, 1997, 2002 and 2010). Latent growth curve models were used to analyse the development. Results: Physical activity slightly increased while fitness, PC and BMI worsened over the course of 18 years. Sex, age and SES play important roles concerning physical activity, fitness and health. Several integrative associations could be detected between physical activity, fitness, PC and BMI as well as their trajectories. In particular, high initial levels of physical activity and fitness protect from high PC and BMI.The slope of physical activity was not significantly associated with slopes of fitness, PC and BMI. However, increase of fitness resulted in decrease of PC. Conclusions: A general positive development regarding the amount of physical activity could be detected. However, if it is only an unsystematic increase of physical activity, this is not in itself enough to achieve health benefits. The strengthening of fitness should be focused when increasing physical activity, since only then a health benefit is possible.  相似文献

Abstract

This study examines the effects of parental attitudes on children's physical activity. A measure of parental attitude (their sport participation when being young) that is independent of the child's behaviour is needed. Using data from the sixth wave of the Taking Part Survey (n =14,002 adults and n =1116 children), a matching estimator analysis is conducted. The results reveal that there are substantial intergenerational transfers of behaviours, in particular for male adults and male children. Furthermore, while an effect is observed for female adults and male children, female children's sport participation is only marginally influenced by female adult's physical activity when growing up. The results imply that promoting sport to the younger generation seems to be a fruitful strategy in creating a sporting habit and promoting sport participation when being older. However, there are challenges to be overcome in promoting female participation.  相似文献

Abstract

The main purpose of this study was to examine typologies of non-exercisers based on reasons for physical inactivity and conditions reported to be necessary to change exercise behaviour. These typologies were then compared on psychological variables of interest and exercise history. Questionnaires were distributed to Greek older adults aged 60 and above who were recruited from social clubs and city cafés. Only individuals engaging in no regular exercise were recruited (n = 188). The results of hierarchical and k-means cluster analyses revealed two clusters for males (“approachable” and “unconvinced”) and three for females (“unconcerned”, “approachable”, and “unconvinced”). The clusters differed significantly on psychological variables not used in the cluster solution. Exercise history distinguished between clusters only among males. The results reveal that physically inactive older adults are not a homogeneous group of individuals. Implementers of physical activity interventions should probably use a range of strategies that take into consideration that some sedentary older adults are more amenable to consider taking up exercise than others.  相似文献

Background: Regular physical activity (PA) is beneficial for physical and psychological well-being, yet many people do not achieve these health benefits due to irregular PA participation which is also known as fluctuation. Limited attention has been given to the phenomenon of fluctuation in the PA behaviour literature. Objective: The aim of this review was to explore and to map definitions, measurements, behavioural evidence, and factors related to PA fluctuation. Methods: Eligible studies were initially identified by a systematic search of articles conducted in four databases: Scopus, PubMed, PsycINFO, and SPORTDiscus between January 1996 and March 2016. Inclusion and exclusion criteria were set to check the eligibility of all articles. Additional articles were included by manual searching and expert recommendation. Results: Fifteen articles were finally included. Definitions of fluctuation are understood from two perspectives, either as a stage in the process of behaviour change, or as a particular PA phenomenon consisting of lapse and readoption. Common features were extracted: behavioural irregularity, high risk of drop-out, intention and readiness for PA, low automaticity, and limited self-regulation. Furthermore, fluctuation identification was summarised in three approaches such as stage algorithm, self-identified PA lapse and readoption, and prospective within-person variation in meeting the PA guidelines. Regarding the empirical evidence, this review found that people in PA fluctuation were significantly distinct from those in preparation and maintenance of PA behavioural performance, as well as distinct in psychosocial features. Conclusions: Notwithstanding the limitations, this review has provided valuable insight into the phenomenon of PA fluctuation.  相似文献

ABSTRACT

Background: School-based physical education has been associated with a multitude of potential learning outcomes. Representatives of a public health perspective suggest that promoting physical activity in and outside the context of school is an important endeavour. While the importance of behavioural skill training to improve (motor) learning is well documented in both general and physical education, the promotion of behavioural skills to foster physically active lifestyles constitutes a rather neglected area in physical education research.

Purpose: To examine whether a standardized physical education-based behavioural skill training program has the potential to positively impact on adolescents’ self-reported exercise and sport participation, as well as cognitive antecedents involved in the regulation of exercise and sport behaviour.

Research design: Cluster-randomized controlled trial.

Methods: A sample of 143 secondary school students (50% girls, aged 14–18 years) attending academic high schools in German-speaking Switzerland were assigned class-wise to the intervention (behavioural skill training) and control condition (conventional physical education lessons). Data were assessed prior and after completion of the 7-week intervention program, which was composed of four 20-min lessons and two reflection phases. Exercise and sport behaviour and cognitive antecedents (exercise/sport intention, motivation, implementation intentions, coping planning, self-efficacy) were assessed via self-reports. A multilevel mixed effects linear regression procedure was used to test the main hypotheses. The regression analyses were adjusted for clustering of school classes, and controlled for baseline levels of the outcome measure and potential confounders.

Results: Compared to a control condition, the intervention program resulted in significant improvements with regard to introjected motivation (p?<?.05), coping planning (p?<?.001) and self-efficacy (p?<?.01). The intervention also had a positive impact on adolescents’ self-reported sport/exercise behaviour (p?<?.001). Improvements in exercise/sport intention (p?<?.05), coping planning (p?<?.01), and self-efficacy (p?<?.01) were associated with increased levels of self-reported exercise/sport participation.

Conclusion: Behavioural skill training as part of compulsory physical education has the potential to improve cognitive antecedents of exercise and sport behaviour and to foster adolescents’ exercise and sport participation. Enhancing behavioural skills might be one way in which school physical education can contribute to the creation of more physically active lifestyles among adolescents.  相似文献

ABSTRACT

Effective and sustainable strategies for physical activity promotion during childhood are of considerable importance to physical education, sport, and health organisations. Multi-component physical activity intervention approaches for children and young people are firmly rooted within the literature; however, there is a dearth of research evidence pertaining to healthy lifestyle promotion within and beyond the school environment. ‘Promoting active lifestyles in schools’ represents a valuable resource for teachers seeking to integrate health-related learning and encourage physically active students. The essential ingredients within this book are the active pedagogies and the health-related learning strategies for children from the ages of 5 to 16 years. Through a consistent formula, this book positions the longitudinal process of health-related learning at the centre of its practice, by providing age-appropriate learning outcomes, activities and assessment strategies within and beyond the school environment. This review seeks to examine the focus of the book and consider its contribution to the existing empirical evidence base within the fields of physical education, health education and physical activity promotion.  相似文献

ABSTRACT

Although the health effects of physical activity during adolescence have been studied less frequently, physical activity seems to have a positive influence on some health concerns in adolescence. Moreover, few studies have reported consistently the relationship between parents’ socio‐economic status (SES) and physical activity habits and adolescents’ activities. Significant physical activity gender differences were reported (p ≤ 0.001). No evidence was found regarding the influence of socio‐economic status on adolescents’ self‐reported physical activity. Mothers (r= 0.23; p ≤ 0.0001) and fathers (r= 0.16; p ≤ 0.05) seem to have a significant influence on adolescents’ physical activity.  相似文献

There is clear evidence of inequalities in the health status of minority ethnic groups in Britain. This includes a number of conditions which may be alleviated or prevented through increased levels of physical exercise. Other research has shown lower levels of activity and raised body mass among Asian groups. There remains some scope for argument about the reasons for these differences. It is, for example, suggested that health education materials are poorly targeted at South Asian communities, or that certain cultures discourage involvement in recreational physical activities. It is known that both motivation and self-image are important to physical activity behaviour, from school age upwards. A lifestyle survey sponsored by the Health Education Authority, and qualitative research, provide an opportunity to examine the degree to which there are distinctive 'ethnic' barriers to exercise or other healthy physical activity amongst communities of South Asian origin living in England. While there are many similarities with the reasons given by members of the white population for 'not exercising', there are some subtle differences between communities, and a number of issues which appear to be specific to the minority populations. Some are particular to a religion, gender or generation. Attention to these, including questions of modesty, gender segregation, and safety, would improve the accessibility of recreational activities to this target group. At the same time, it is clear that individuals from these communities are well informed and well motivated, and do take advantage of local facilities when they can. The question of both institutional and personal racism cannot be excluded from a strategy for promoting healthy physical activity; equally, it is important to pay attention to the characteristics of particular communities to gain their confidence. A 'colour-blind' or homogenous approach may be counterproductive.  相似文献

ABSTRACT

This study compared five different methods for analyzing accelerometer-measured physical activity (PA) in older adults and assessed the relationship between changes in PA and changes in physical function and depressive symptoms for each method. Older adult females (N = 144, Mage = 83.3 ± 6.4yrs) wore hip accelerometers for six days and completed measures of physical function and depressive symptoms at baseline and six months. Accelerometry data were processed by five methods to estimate PA: 1041 vertical axis cut-point, 15-second vector magnitude (VM) cut-point, 1-second VM algorithm (Activity Index (AI)), machine learned walking algorithm, and individualized cut-point derived from a 400-meter walk. Generalized estimating equations compared PA minutes across methods and showed significant differences between some methods but not others; methods estimated 6-month changes in PA ranging from 4 minutes to over 20 minutes. Linear mixed models for each method tested associations between changes in PA and health. All methods, except the individualized cut-point, had a significant relationship between change in PA and improved physical function and depressive symptoms. This study is among the first to compare accelerometry processing methods and their relationship to health. It is important to recognize the differences in PA estimates and relationship to health outcomes based on data processing method.

Our understanding of the relationship between physical activity and health is constantly evolving. Therefore, the British Association of Sport and Exercise Sciences convened a panel of experts to review the literature and produce guidelines that health professionals might use. In the ABC of Physical Activity for Health, A is for All healthy adults, B is for Beginners, and C is for Conditioned individuals. All healthy adults aged 18–65 years should aim to take part in at least 150 min of moderate-intensity aerobic activity each week, or at least 75 min of vigorous-intensity aerobic activity per week, or equivalent combinations of moderate- and vigorous-intensity activities. Moderate-intensity activities are those in which heart rate and breathing are raised, but it is possible to speak comfortably. Vigorous-intensity activities are those in which heart rate is higher, breathing is heavier, and conversation is harder. Aerobic activities should be undertaken in bouts of at least 10 min and, ideally, should be performed on five or more days a week. All healthy adults should also perform muscle-strengthening activities on two or more days a week. Weight training, circuit classes, yoga, and other muscle-strengthening activities offer additional health benefits and may help older adults to maintain physical independence. Beginners should work steadily towards meeting the physical activity levels recommended for all healthy adults. Even small increases in activity will bring some health benefits in the early stages and it is important to set achievable goals that provide success, build confidence, and increase motivation. For example, a beginner might be asked to walk an extra 10 min every other day for several weeks to slowly reach the recommended levels of activity for all healthy adults. It is also critical that beginners find activities they enjoy and gain support in becoming more active from family and friends. Conditioned individuals who have met the physical activity levels recommended for all healthy adults for at least 6 months may obtain additional health benefits by engaging in 300 min or more of moderate-intensity aerobic activity per week, or 150 min or more of vigorous-intensity aerobic activity each week, or equivalent combinations of moderate- and vigorous-intensity aerobic activities. Adults who find it difficult to maintain a normal weight and adults with increased risk of cardiovascular disease or type 2 diabetes may in particular benefit from going beyond the levels of activity recommended for all healthy adults and gradually progressing towards meeting the recommendations for conditioned individuals. Physical activity is beneficial to health with or without weight loss, but adults who find it difficult to maintain a normal weight should probably be encouraged to reduce energy intake and minimize time spent in sedentary behaviours to prevent further weight gain. Children and young people aged 5–16 years should accumulate at least 60 min of moderate-to-vigorous-intensity aerobic activity per day, including vigorous-intensity aerobic activities that improve bone density and muscle strength.  相似文献

Background: Population health concerns related to physical inactivity and obesity appear in policy documents, government campaigns and popular media across western societies. Children and young people have been targeted for physical activity promotion and schools have been positioned as sites for intervention. In particular, Physical Education and school sport (PESS) has been framed as a key part of the solution. While some interventionist programmes in schools have reported positive outcomes, they have also been criticised for stigmatising fatness, contributing to a culture of surveillance and fuelling body image anxieties. Despite ongoing work to ameliorate these critical issues by addressing physical activity promotion discourses, curricula and teaching practices many of the same challenges persist. In seeking alternative explanations (and solutions) this paper shifts attention to exploring the role of pupils and their peers.

Purpose: While the critical literature on health and physical education has been illuminating, few studies explore the role of pupils and their peers. Further research is necessary to understand how school peers contribute to pupils’ engagement with PESS. This paper, therefore, draws on Bourdieu’s notion of physical capital and seeks to understand how pupils’ physical activity is influenced by lived-body experiences in school spaces.

The study: Data were produced from a 6-month bricolage-based study with pupils (N?=?29, aged 13–14) across four diverse school settings in England. Multiple qualitative methods were deployed to enhance methodological rigour with what is often a challenging age group for research. Data were interpreted and theorised using the concept of physical capital.

Findings: Pupils themselves play a significant part in establishing the physical body as a symbol of power and status in school settings. Participants understood the health risks of being both underweight and obese, but they regarded obesity as being more problematic because of the immediate social risks of ‘standing out as the bigger one’. Following this rationale, participants sought to accumulate physical capital through engaging in exercise as a purposeful calorie-burning activity intended to avoid the pity, abnormality and derision which is expected to be directed towards overweight pupils. Furthermore, during PESS in clear view of peers, distinctions between pupils’ physical capital could be made by recognising differences in sporting skill. In this context, physical capital mediated engagement in PESS in various ways.

Conclusion: This study has revealed that peers play a significant part in constructing the lived-body experiences of young people. In order to address the criticisms raised about some school-based health promotion interventions, it is crucial to attend to pupils’ relationships with peers as well as addressing policies, curricula and teaching practices. Being sensitive to peer relationships and their understanding of health may help teachers and health promoters decide how to manage the spaces where PESS takes place.  相似文献
