This study examined the effects of utilizing a wearable activity tracker in a credit-based physical activity instructional program (PAIP) for promoting physical activity (PA) in college students. Fourteen PAIP courses in a large public university were randomly assigned into intervention (k = 7; n = 101) and control (k = 7; n = 86) groups. All courses focused on a core curriculum that covers basic exercise and behavioral science contents through lectures and activity sessions. A Misfit Flash activity tracker was provided to students in the intervention group. Objective PA assessments occurred at baseline, mid-, and end-of-semester during a 15-week academic semester. The control group showed a significant reduction in moderate- and vigorous-intensity PA (MVPA) minutes from baseline to the end-of-semester (P <.05), whereas the intervention group showed no changes in MVPA minutes over time. However, the intervention group also showed increased sedentary time and decreased time spent in light-intensity PA during the intervention period. Taken together, the present study found null effects of utilizing the wearable activity tracker in promoting PA in college students suggesting that intervention of primary using the wearable activity tracker as a behavior change strategy may not be effective to increase in PA in this setting.  相似文献

Using visual methodologies to understand pre-service Health and Physical Education teachers’ subjectivities of bodies     

Valeria Varea  Bonnie Pang 《Sport, Education and Society》2018,23(5):394-406

Socio-cultural theorists have argued that having a diverse understanding of subjectivities of normal/ideal bodies is important for Health and Physical Education (HPE) teachers. When teachers hold a single understanding and perception of normal/ideal bodies, such as a thin body as normal or ideal body, which are usually informed by dominant discourses, they may (re)produce narrow understandings of bodies among their students. This paper focuses on how a group of pre-service HPE specialist teachers (11 females and 3 males, aged between 18 and 26 at the time of the first interview) from an Australian university, discuss issues related to subjectivities of bodies. It draws on visual methodologies and semi-structured interviews to understand how these pre-service HPE specialist teachers construct discourses of bodies. Foucault’s concepts of normalisation, surveillance and biopedagogies are used to explore discursive constructions of bodies, with a particular focus on how some discourses are normalised via surveillance techniques. The results of the study invite us to reflect on how images may promote certain ways of thinking about and considering the body among pre-service HPE specialist teachers. In light of contradictions which were found across the comments of two participants who constructed different discourses during the interviews, we posit that making sense of subjectivities of bodies is complex and often contradictory. Furthermore, the results suggest that photo elicitation is a useful visual method for theorising issues related to bodies. Results can inform teacher education and policy in how to better prepare pre-service HPE teachers to teach about bodies.  相似文献

【目的】 为期刊编辑及时、准确地处理Meta分析类稿件提供参考依据，以期提高期刊编辑的工作效率和期刊来稿质量。【方法】 调查2011年11月1日—2017年11月1日《中国卫生统计杂志》在线投稿系统中Meta分析类稿件，深入分析119篇样本稿件的审理过程，归纳退稿原因并总结审稿策略。【结果】 119篇稿件中，仅33篇稿件已发表，20篇稿件仍在审理过程中，66篇稿件被退稿。退稿原因包括选题创新性差、文献检索不当、文献纳入与排除标准不严谨、流程图不规范、异质性分析不当、发表偏倚分析不当、讨论欠佳等。【结论】 编辑审读Meta分析类稿件时，应加强主题选取和相关文献的搜集、纳入文献的筛选方法及质量评价、数据的统计学处理和结果解释4个方面的审查，减少不合格文献的数量。  相似文献   

Agency,sociomateriality, and configuration work     

Mohammad Hossein Jarrahi  Sarah Beth Nelson 《The Information Society》2018,34(4):244-260

Social informatics research offers insights into the relationship between information technologies and social contexts. However, the material roles of information technologies, and their interplay with the agentic work of social actors, have not been addressed. Drawing on a field study of 37 mobile knowledge workers, we examine the dual material roles (enabling and constraining) played by information technologies in their work practices. We also investigate how these workers exert agency by fashioning multiple information technologies into a functioning digital assemblage. Although information technologies provide consequential affordances that enable mobilization of work across spaces and times, they simultaneously present design-driven, local, organizational, and temporal technological constraints that require mobile knowledge workers to engage in “configuration work” to make information technologies function effectively. Building on a sociomaterial perspective, we further discuss the interplay of information technologies and work practices enacted by mobile knowledge workers, in which both human and technological agency are materialized.  相似文献   

健身气功·气舞的名称、功理及美学问题研究     

王英璟  项汉平  任克 《武汉体育学院学报》2018,52(9):66-71

健身气功是我国民族传统体育项目的重要组成部分，健身气功·气舞是其在追求艺术美感方向上的最新尝试。该文主要运用文献资料法、专家访谈法，以对健身气功·气舞裁判规则、实践情况以及后续影响的分析为基础，以健身气功功法原理为根本，依次从健身气功·气舞的名称、功理和审美观三个层面对存在的问题进行剖析。研究显示：健身气功·气舞在名称序列上的不对应性和旨意的不确定性会影响受众的理解；对健身气功功理诸如外在神态、练养结合等的疏忽会使"功"朝着"舞"的方向发展；健身气功·气舞中附加元素过多无助于审美移情的产生和固有境界的营造，目前其发展方式也与绿色简约审美观有所背离。进而，针对这些问题提出了相应的建议。  相似文献   

Framing citizenship: from assumptions to possibilities in health and physical education     

Alison Wrench 《Sport, Education and Society》2019,24(5):455-467

Within the Australian context physical education (PE) and more recently health and physical education (HPE) have long been ascribed utilitarian value for producing healthy citizens. Whilst this has not been a linear progression over time, traces from the past do inform current assumptions about this utilitarian role. Of consequence are historical contingencies and responses to societal problems around health-related conduct and capabilities of the nations’ citizens. In this paper a genealogical approach is adopted to explore discourses and power relations that have framed the contribution of PE and HPE in shaping students for healthy citizenship. Disciplinary technologies associated with military-style physical training, civilising technologies of game play and responsibilising governmental technologies of contemporary policies will be explored. I conclude in arguing that if HPE is to prepare all students for equitable, inclusive citizenship what is required is the adoption of curricula and pedagogies that counteract hegemonic notions of individual responsibility for healthy citizenship.  相似文献   

Visual function,performance, and processing of basketball players vs. sedentary individuals     

Jesús Vera  Raimundo Jimnez  David Crdenas  Beatriz Redondo  Jos Antonio García 《运动与健康科学(英文)》2020,9(6):587-594

BackgroundAthletes tend to have better visuo-motor performance than do sedentary individuals. However, several basic visual-function and perceptual parameters remain unexplored to date. In this study, we investigated whether differences exist in visual function, performance, and processing between basketball players and individuals without a sport-involvement background.MethodsA total of 33 healthy men with no visual impairment or pathology were divided into 2 groups, depending on the involvement in sport (semi-professional basketball players and sedentary individuals). We tested their baseline heart-rate variability in the resting position apart from subjective questionnaires to determine their physical fitness level, and we checked their visual function, performance, and processing through an extended battery of optometric tests.ResultsThe 2 groups differed in resting heart-rate variability parameters (p < 0.001), confirming their dissimilarities in regular time practising sports per week. The basketball players showed a closer breakpoint and recovery nearpoint of convergence, a higher fusional-vergence rate, better discriminability halos, and better eye–hand coordination (all p values < 0.05).ConclusionThese results show evidence that athletes, basketball players in this case, exhibit better performance in several visual abilities in comparison to a group of individuals without sporting backgrounds, suggesting an improvement due to the systematic involvement of those skills during basketball practice.  相似文献
