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

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.     

全民健身服务体系中公益与商业的协调互动研究*

自从1996年国务院提出“全民健身工程”的概念之后，全面健身在全社会掀起了一股热潮，然而20多年过去了，全民健身这项公益事业的规模和水平还远未满足人民群众的要求，因此，今天人们又重新提出构建全民健身服务体系的新思路。全民健身对于政府来说是一项重要的公益事业，政府投入全民健身工程建设应以社会效益为其关注点。全民健身又是一个拥有庞大市场的商机，企业参与全民健身服务体系建设则应在公益法规之下获取有限的公益利益。平衡政府与企业间的利益才能真正使政府资金和民间资本协调配合，促使全民健身服务体系快速完善地构建起来。     

Striving to Be King of Mobile Mountains: Communication and Organizing Through Digital Fitness Technology

This study considers fitness-tracking applications as settings for communicative performances. Qualitative interviews and observations with 41 users of a cycling-focused fitness application revealed communicative themes of qualifying, social sharing, and withholding. Users also assessed other members through social-group comparing and upward comparing. This study develops theory by revealing how individuals use the technology to communicate about their physical acts, and how the context of use facilitates organizing processes. We argue that use of this fitness application extends our understanding of how communication can constitute a community of practice (CoP; Brown & Duguid, 1991; Lave & Wenger, 1991). Primarily, the hybrid online/offline nature of Strava complicates the traditional understanding of communication and CoPs.
