Background:Physical activity(PA)may have an impact on digestive-system cancer(DSC)by improving insulin sensitivity and anticancer immune function and by reducing the exposure of the digestive tract to carcinogens by stimulating gastrointestinal motility,thus reducing transit time.The current study aimed to determine the effect of PA on different types of DSC via a systematic review and meta-analysis.Methods:In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)guidelines,we searched for relevant studies in PubMed,Embase,Web of Science,Cochrane Library,and China National Knowledge Infrastructure.Using a random effects model,the relationship between PA and different types of DSC was analyzed.Results:The data used for meta-analysis were derived from 161 risk estimates in 47 studies involving 5,797,768 participants and 55,162 cases.We assessed the pooled associations between high vs.low PA levels and the risk of DSC(risk ratio(RR)=0.82,95%confidence interval(95%CI):0.79-0.85),colon cancer(RR=0.81,95%CI:0.76-0.87),rectal cancer(RR=0.88,95%CI:0.80-0.98),colorectal cancer(RR=0.77,95%CI:0.69-0.85),gallbladder cancer(RR=0.79,95%CI:0.64-0.98),gastric cancer(RR=0.83,95%CI:0.76-0.91),liver cancer(RR=0.73,0.60-0.89),oropharyngeal cancer(RR=0.79,95%CI:0.72-0.87),and pancreatic cancer(RR=0.85,95%CI:0.78-0.93).The findings were comparable between case-control studies(RR=0.73,95%CI:0.68-0.78)and prospective cohort studies(RR=0.88,95%CI:0.80-0.91).The meta-analysis of 9 studies reporting low,moderate,and high PA levels,with 17 risk estimates,showed that compared to low PA,moderate PA may also reduce the risk of DSC(RR=0.89,95%CI:0.80-1.00),while compared to moderate PA,high PA seemed to slightly increase the risk of DSC,although the results were not statistically significant(RR=1.11,95%CI:0.94-1.32).In addition,limited evidence from 5 studies suggested that meeting the international PA guidelines might not significantly reduce the risk of DSC(RR=0.96,95%CI:0.91-1.02).Conclusion:Compared to previous research,this systematic review has provided more comprehensive information about the inverse relationship between PA and DSC risk.The updated evidence from the current meta-analysis indicates that a moderate-to-high PA level is a common protective factor that can significantly lower the overall risk of DSC.However,the reduction rate for specific cancers may vary.In addition,limited evidence suggests that meeting the international PA guidelines might not significantly reduce the risk of DSC.Thus,future studies must be conducted to determine the optimal dosage,frequency,intensity,and duration of PA required to reduce DSC risk effectively. 相似文献

Abstract The Great War contributed greatly to challenge the gender order in France, a context that resulted in both a crisis of masculinity and a certain freedom of women. As a reaction, men and women were redefined in the aftermath of the First World War according to traditional gender expectations. This return to tradition was especially reflected in the new official discourse on physical education. Between 1919 and 1927, the so-called “French Method of Physical Education” was written by the Military School of Joinville-Le-Pont and immediately imposed on the State school system for all French pupils. Consisting of three large volumes, the “French Method” offers an excellent tool to explore how the French State redefined the gender relations and presented ideal models of masculinity and femininity. The issue is of particular interest because the “French Method” became compulsory for almost half a century in France and was largely disseminated throughout the world. 相似文献

The role of schools and physical education in promoting health, producing a ‘healthy nation’ and in tackling obesity has been increasingly recognised in recent years. In England this is evidenced by various policies, strategies and responses from government that have highlighted schools to be instrumental in addressing health broadly and obesity specifically. In addition, individual schools and teachers at the local level appear to be responding to the obesity issue in varied and different ways. However, we and other researchers feel that the discourse surrounding obesity and some of the reports, messages, policies and measures being taken to tackle it are misleading, misguided and could do more harm than good. At the same time, as physical educators committed to the health and development of young people, we feel unable to ignore the issue and compelled to act. We contend that ‘every child of every size matters’ and can benefit from regular engagement in physical education and physical activity and furthermore that, as a profession, we have a responsibility to provide all young people, of all sizes, with meaningful, relevant and positive physical education and physical activity experiences. Given this, we consider what role physical education can and should realistically, sensibly and safely play in addressing childhood overweight and obesity. Firstly, some of the key ‘facts’, issues and debates concerning obesity are explored and the way in which the issue appears to be being addressed in many schools is critiqued. We then briefly summarise some of the formal guidance and recommendations available to schools on obesity, before concluding with some practical recommendations to support physical education teachers in effectively engaging all children in physical activity both within and beyond physical education. 相似文献

Physical education is a socially constructed activity that forms one component of a wider physical culture that includes sport and health/physical activity . The terms sport and physical education are often used interchangeably in school contexts, where sport and health continue to shape what is understood by the term physical education. This study explores discourses shaping pre-service primary teachers' understandings of the nature and purposes of physical education within an Irish context and the relationship between these understandings. A 10-minute writing task prompted by the question ‘what is physical education?’ was completed by a sample of pre-service teachers (n=544, age range 18–46, 8.8% male) from two colleges of education, prior to the physical education component of their teacher education programme. Content analysis involved an initial text frequency search to create categories which were collapsed into three broad areas of students' understandings of physical education—sport, health and physical education. The research design allowed access to pre-service teachers' understandings of physical education. Participants' understandings reflected their own school experiences and were framed within health and sport ideologies of physical education. Although acknowledged as an important part of school life physical education was perceived as a break from academic subjects where the purpose of learning was to learn sports and activities to stay fit and healthy. While the overwhelmingly positive nature of participants' experiences and the changing discourses around competition and team games are encouraging the dominant discourses of physical education continue to reflect the dominant aspects of wider physical culture in Ireland. The capacity of physical education to move beyond reproducing dominant sport and health ideologies provides a significant challenge to teacher education contexts, to challenge dominant discourses and recreate understandings of physical education for future action. 相似文献

This paper explores socio-ecological factors and their interplay that emerge from a qualitative study and influence adolescents' physical activity and sport participation. A total of 13 boys and 7 girls active and inactive adolescents, from years 12 and 13 and different types of school (state and private), participated in semi-structured interviews. It followed a purposeful sampling selection from participants who participated in a previous larger study on physical activity levels. Findings highlight the influence of personal and social interplay, such as perceived competence, obesity and teasing from peers, and new social demands and personal preferences in adolescents' (dis)engagement in physical activity and sport. They also stand out how social and environmental factors affect their participation, such as family, boy/girlfriends, physical education and rural/urban places of residence. These factors appear to have an important impact on the construction of (in)active identities during late adolescence. Policy makers, exercise professionals and educators should be aware of these factors in order to improve health promotion strategies and social policies. Some recommendations are also indicated in the paper. 相似文献

This paper explores the physical education (PE) and physical activity experiences of a group of South Asian, Muslim girls, a group typically marginalised in PE and physical activity research. The study responds to ongoing calls for research to explore across different spaces in young people's lives. Specifically, I draw on a ‘middle-ground’ approach, using Hill Collins' matrix of domination and the notion of intersectionality. These concepts offer the possibility to explore the kinds of settings (physical, social and cultural) in which girls undertake PE and physical activity, how these spaces influence experience and how the girls navigate these spaces. The study is based in a large, urban, co-educational, secondary school in Yorkshire, England (95% of the students are from minority ethnic communities, 91% are Muslim and 63% live in the top 10% most deprived neighbourhoods in the country). Data generation involved three phases: observations, creating research artefacts in focus groups and in-depth interviews. The findings reveal the diverse ways the girls are physically active. They also demonstrate a complexity to their involvement which is contingent upon space, discourses and people. For example, discourses of competition, ability and peers are more significant within PE; whilst family, religion and culture feature beyond this context. The paper concludes by acknowledging the girls' heterogeneity and agency in the ways they strategically navigate spaces in their quest to be physically active on their terms. 相似文献

This article takes a point of departure in the debate whether physical education should consider a limited or an increased commitment towards public health goals and a public health agenda. The article further discusses the relationship between physical activity and health, and the perspective of health in physical education. This is done through a critique of the dominance of a pathogenic perspective of health, as well as through a salutogenic approach regarding health as a process. A salutogenic approach makes, as suggested in the article, other questions—salutogenic questions—possible. In this sense, physical activity and movement can be regarded as something more than mere protection against disease or overweight, and by posing salutogenic questions we can enrich our understanding of the relation between physical activity and health, and in consequence richness to the perspective of health in physical education. With a salutogenic approach, the pupils’ unique and common experiences of health, movement, body ideals or outdoor-life can meet a wider perspective of health. This would facilitate a health perspective in physical education that draws attention to the qualities, abilities and knowledge that pupils can develop, and, in the name of learning health, point the way to the possible contribution of physical education in pupils’ health development in terms of how physical education can enrich their lives, strengthen them as healthy citizens and contribute to a sustainable (health) development. 相似文献

In the debate over health, one political message has become more and more dominant in western societies over the past decade: Get moving! The logic seems to be that physical activity per se equals better health and that the more physical activity, the better one's health. This logic has, among other things, induced an increased political focus on educational settings and physical education (PE) as a central place for promoting health by increasing physical activity. Today PE is often explicitly identified with health in contemporary school curricula, and this means that PE teachers unavoidably encounter contemporary perceptions of health and physical activity in their professional practice. Taking as its starting point four different teaching resources produced for health education in the Danish Primary School, this article presents four different health cultures and their recommendations for physical activity as a health-promoting practice. The aim is to challenge current perceptions of health and the related recommendations for physical activity in providing a springboard for health communicators and PE teachers to reflect on the health cultures they encounter and maybe to consider how these aligns their own preferred health culture. 相似文献

Various government policies, strategies and responses in England over the years have highlighted schools and physical education to be instrumental in addressing health and the focus on health has been strengthened within subsequent revisions of the National Curriculum. Whilst this might seem encouraging, concerns have been expressed that such policies and governmental regulation increasingly bear features of a ‘performative culture’ and that these have led to increasingly widespread health surveillance in schools. Linked to this are long-standing concerns over the way in which health is addressed in schools and physical education, as well as over some of the monitoring measures and practices employed within the curriculum. Despite this, little is known about monitoring practices in physical education. This article, therefore, presents findings of a study which aimed to (1) determine the nature, prevalence and purpose of monitoring health, physical activity and physical fitness within the physical education curriculum and (2) establish physical education teachers' views of and approaches to monitoring. The study comprised two phases. The first phase involved a survey completed by Heads of Physical Education in 110 secondary schools from across England, and the second semi-structured interviews with 18 of those from the original sample. The findings revealed monitoring, and in particular fitness monitoring, to be a common feature within the physical education curriculum in many schools. However, a number of issues and limitations associated with monitoring and some of the schools' monitoring practices were identified, and the individualistic nature and performative culture reflected in and reinforced through monitoring were acknowledged as potentially problematic. It was thus suggested that if the findings are typical, then monitoring practice is currently not in a good state of health. The article concludes proposing a way forward for monitoring within physical education in the form of some recommendations for practice. 相似文献

In this study, we used the trans-contextual model of motivation (TCM) to examine the effect of Sport Education (SE) on students' participation in a voluntary lunch recess sport club. A total of 192 participants (ages 9-14 years) completed measures of the TCM constructs before and after a 12-week SE intervention period. Participants had the opportunity to participate in weekly, voluntary lunch recess sport club sessions during the intervention period. SE elicited a moderate increase in autonomous motives in physical education. The TCM accounted for a significant proportion of the explained variance in lunch recess sport club intention and participation. Autonomy-supportive curricular models, such as SE, may have the potential to facilitate transfer of motivation and participation in physical activity from a physical education to an extracurricular context. 相似文献

There would appear to be an enduring belief that successful sportsmen and women can act as powerful motivational role models for young people, especially disaffected, disadvantaged or disengaged youth. In the UK, for example, this belief has been expressed recently in the development of programmes, such as changingLIVES, the Respect Athlete Mentor Programme and Playing For Success. There are further examples around the world of programmes based on similar beliefs including Sporting Partnerships, Athlete Development Australia, Active Girls Breakfast and the Whitelion Sports and Recreation program. This paper reports an evaluation of the changingLIVES ‘athlete mentor’ programme in the UK. This was a school-based programme using successful sports people to deliver a series of motivational activities to young people who were identified as being disengaged or disaffected in some way. Conceptual confusion in the terms ‘mentor’ and ‘role model’ evident in the literature was mirrored in the programme design. The design of an appropriate evaluation strategy was constrained by the scale of the programme aims and the comparatively low evaluation budget. Nonetheless, detailed data were collected on individual pupils. Evaluation data suggested that although the teachers and young people did report an immediate positive reaction to the activities, there was limited evidence of a wider impact on young people's behaviour, school attendance or self-esteem. It is argued that there should be greater conceptual clarity and a stronger evidence base supporting the design and delivery of interventions in schools that seek to use sports people as role models (or mentors) for young people. 相似文献

A legacy emphasis was one of the fundamental pillars of the London 2012 Olympic Games. The notion of an Olympic legacy was predicated on assumptions that the event's value would not purely derive from the sporting spectacle, but rather from the ‘success’ of enduring effects met out in London and across the country. For physical education students and practitioners, Olympic legacy agendas translated into persistent pressure to increase inspiration, engagement, participation and performance in the subject, sport and physical activity. Responding to this context, and cognizant of significant disciplinary scholarship, this paper reports initial data from the first phase of a longitudinal study involving Key Stage Three (students aged 11–13) cohorts in two comparable United Kingdom schools: the first an inner-city (core) London school adjacent to the Olympic Park in Stratford, East London (n = 150); the second a (peripheral) school in the Midlands (n = 198). The research involved the use of themed questionnaires focusing on self-reported attitudes towards the Olympic Games and experiences of physical education, sport and physical activity. Students from both schools demonstrated a wide variety of attitudes towards physical education and sport; yet, minor variances emerged regarding extreme enthusiasm levels. Both cohorts also expressed considerably mixed feelings towards the impending Olympic Games. Strong and variable responses were also reported regarding inspiration levels, ticketing acquisition and engagement levels. Consequently, this investigation can be read within the broader context of legacy debates and aligns well with physical educationalists' ongoing discomfort regarding legacy imperatives being enforced upon the discipline and its practitioners. Our work reiterates a shared disciplinary scepticism that while an Olympic Games may temporarily affect young peoples' affectations for sport (and maybe physical education and physical activity), it may not provide the best, or most appropriate, mechanism for sustained attitudinal and/or social changes en masse. 相似文献
