‘Who is zooming who’? A study of young PE-students in their figurations

The article presents an analysis of 93 essays written in an upper secondary school context. The essays were collected in relation to a larger research project, which went on for 5 years in a Danish upper secondary school (2010–2015). The material represents both genders and the students are 15–17 years old. We deploy a theoretical framework taken from Norbert Elias’ notion on established-outsider relations [Elias, N., &; Scotson, J. L. (1994 [1965]). The established and the outsiders. London: SAGE] as well as his use of personal pronouns [Elias, N. (1978). What is sociology? London: Hutchinson, Elias, N. (2001). The society of individuals. New York: The Continuum International Publishing Group] in illustrating how people negotiate, position and navigate within figurational contexts [Elias, N. (1994 [1939]). The civilizing proces. Oxford: Blackwell.]. We do this in an effort to interpret how young people negotiate ‘we-I-relations’ when it comes to their sporting identity. Elias’ processual framework provides a tool for a much needed analysis of how young people continually orientate and develop their sense of selves. The web of human interdependencies and processes of change are key words when it comes to understanding the social practices and doings of the students’ constructions of self-steering. What social scientists may see as laziness and drop-outs of sports [Seippel, Ø. (2016). Prek, vekker og kjedelig? Trening og mening blant ungdom: 1985–2013. In Ø. Seippel, M. K. Sisjord, &; Å Strandbu (Eds.), Ungdom og Idrett. Oslo: Cappelen Damm Akademisk] can in the essays of students be analysed as a struggle for group connectedness and social inclusion in the classroom. The results of our research show that identity is a multiple concept and an ongoing process of emotional work [Elias, N. (1987). On human beings and their emotions: A process-sociological essay. Theory Culture Society, 4, 339–361], but also a power balance of playing and presenting what is imagined as the right performance as not being shamed as outcasts.     

The carbon footprint of active sport participants

Researchers examining carbon dioxide-equivalent emissions (carbon footprint) in sport have focused on sport events and, to a lesser extent, sport teams, but provided only average or aggregate values. The author takes the perspective of active sport participants and considers the heterogeneity of individual sport participation behavior. Using online surveys, adult active sport participants (n = 6537) in 20 different sports with main residence in Germany were asked to report their sport-travel behavior in 2015, including traveling in the context of regular (weekly) activity, sport competitions/tournaments, league games, day trips, and training camps/vacations. Annual carbon footprints were estimated using information about travel distances and transportation means. The results revealed an average annual carbon footprint of 844 kg of carbon dioxide-equivalent emissions, with individual sports producing more emissions than team/racket sports. Participants in nature sports had the highest emission levels. Regression analyses revealed that environmental consciousness significantly reduced carbon footprint in individual sports, but not in team/racket and nature sports, supporting the existence of an environmental value-action gap. Activity years, club membership, weekly exercise hours, performance level, and income were mainly positively associated with annual carbon footprint, while gender was insignificant. The findings have implications for policy makers and managers in sport associations and clubs.     

Sport as medicine: How F3 is building healthier men and communities

Given sport has been largely absent from U.S. public health policies and discourse, the author suggests ways that sport can be better managed to promote health. Using a critical perspective and grounded theory approach, the author examined the experiences of 14 men in the grassroots recreational program, F3. Data were collected through observation and semi-structured interviews. Based on the results, a conceptual model that suggests how sport should be managed to address illnesses related to physical inactivity is put forth. The resulting Sport as Medicine model indicates that Creating a Team Structure, Providing a Place to Be Accountable, and Ensuring No One is Left Out, led to meaningful Health Outcomes, including Physical Health, Mental Toughness, and Social Connections. As the distinctiveness of sport continues to emerge, the author provides a framework to consider how sport can be part of public health efforts to address physical inactivity. Thus, this work positions sport as medicine by pinpointing how sport can be managed so that holistic health outcomes are more likely achieved.     

近10年中国新疆与中亚对外贸易依存性发展

对中国新疆与中亚2005-2014年10年间对外贸易发展变化进行对比分析,研究在时间尺度上双方贸易额、贸易结合度、贸易差额及贸易发展环境的动态变化。结果表明：新疆对中亚国家贸易额逐年提升,在中国对中亚贸易中比例逐年下降;双方贸易结合度高,但结合度在逐年下降;新疆对中亚国家存在较大的贸易顺差,并且差额在持续扩大;新疆贸易发展环境优于中亚国家,近年双方贸易环境日趋转好。为进一步优化双方贸易,提出如下建议：加强新疆加工贸易的发展,提高进口原料的消化能力;加强新疆从中亚国家的进口工作,平衡双方贸易差额;积极推进双边自由贸易区的建设。     

Temporal trends in 6-minute walking distance for older Japanese adults between 1998 and 2017

BackgroundThe 6-minute walking distance (6MWD) is an excellent measure of both functional endurance and health. The primary aim of this study was to estimate temporal trends in 6MWD for older Japanese adults between 1998 and 2017; the secondary aim was to estimate concurrent trends in body size (i.e., height and mass) and self-reported participation in exercise/sport.MethodsAdults aged 65–79 years were included. Annual nationally representative 6MWD data (n = 103,505) for the entire period were obtained from the Japanese Ministry of Education, Culture, Sports, Science and Technology. Temporal trends in means (and relative frequencies) were estimated at the gender–age level by best-fitting sample-weighted linear/polynomial regression models, with national trends estimated by a post-stratified population-weighting procedure. Temporal trends in distributional variability were estimated as the ratio of coefficients of variation.ResultsBetween 1998 and 2017 there was a steady, moderate improvement in mean 6MWD (absolute = 45 m (95% confidence interval (95%CI): 43–47); percent = 8.0% (95%CI: 7.6%–8.4%); effect size = 0.51 (95%CI: 0.48–0.54)). Gender- and age-related temporal differences in means were negligible. Variability in 6MWD declined substantially (ratio of coefficients of variation = 0.89, 95%CI: 0.87–0.92), with declines larger for women compared to men, and for 75–79-year-olds compared to 65–74-year-olds. Correspondingly, there were moderate and negligible increases in mean height and mass, respectively, and negligible increases in the percentage who participated in exercise/sport at least 3 days per week and at least 30 min per session.ConclusionThere has been a steady, moderate improvement in mean 6MWD for older Japanese adults since 1998, which is suggestive of corresponding improvements in both functional endurance and health. The substantial decline in variability indicates that the temporal improvement in mean 6MWD was not uniform across the distribution. Trends in 6MWD are probably influenced by corresponding trends in body size and/or participation in exercise/sport.

分析双边贸易强度、产业结构相似度、出口结构相似度和产业内贸易指数与经济周期协动性的相关性,利用1990-2011年的季度数据建立OLS与3SLS模型对比分析中日经济周期协动性的贸易传递效应,研究结果表明：双边贸易强度、产业结构相似度、出口结构相似度以及产业内贸易与经济周期协动性是正相关的;在经济周期协动性的贸易传导因素中,产业结构相似度对经济周期协动性的影响系数最小,出口结构、产业内贸易相似度对经济周期协动性的影响较大.     

儿童青少年体能发展敏感期相关热点问题

近年来,旨在提高儿童青少年体质健康的研究众多,其中儿童青少年体能发展敏感期问题的研究正成为热点研究。通过文献资料法和逻辑分析法等,对近30年来“敏感期”相关文献进行梳理。研究表明：国内外“敏感期”的界定标准不统一,难以形成科学成果;“敏感期”干预方法单一,缺乏综合干预方法;“敏感期”与“非敏感期”干预效果的研究还存在争议。研究认为：“敏感期”不仅受儿童青少年生理、心理因素的影响,同时遗传、环境、社会经济等对“敏感期”也具有重要作用。因此,未来应深入研究“敏感期”的构成因素,重视理论研究与实践研究相结合,强化“敏感期”的综合研究。
