Background: Among numerous health benefits, sports participation has been shown to reduce the risk of overweight and obesity in children and adolescents. Schools represent an ideal environment for increasing sports participation, but it is unclear how access and choice influence participation and whether characteristics of the school sports program differentially influence boys' and girls' participation. The purpose of this study was to evaluate the characteristics of high school athletic programs and determine the extent to which these characteristics influenced boys' and girls' sports team participation. Methods: Longitudinal telephone surveys were conducted with 1244 New Hampshire and Vermont students. Students self-reported their sports team participation at baseline (elementary school) and follow-up (high school). High school personnel were surveyed to assess sports oppor- tunities, which were defined for this analysis as the number of sports offered per 100 students (i.e., choice) and the percent of sports offered that did not restrict the number of players (i.e., access). Results: Approximately 70% of children participated on at least one sports team, including 73% of boys and 66% of girls. We detected sta- tistically significant interactions between sex and two school opportunity variables: 1) the number of sports offered per 100 students (i.e., choice) and 2) the percent of sports offered that did not restrict the number of players (i.e., access). After controlling for children's baseline sports participation and other covariates, boys were more likely to play on at least one sports team per year if their school did not restrict participation in the most popular sports (relative risk, RR = 1.12, p 〈 0.01); in contrast, girls were more likely to play on at least one sports team per year if their school offered a wider variety of sports (RR = 1.47, p 〈 0.001). Conclusion: Sports participation has previously been shown to confer a number of health benefits; as such, school sports programs may be an important, effective, and underused target for public health efforts, including obesity prevention programs. Efforts to increase physical activity among youth should consider both access and choice in school athletic programs. Schools may need to use different strategies to increase sports participation in boys and girls. 展开更多

The core idea of physical literacy is a mind-body integrated, holistic approach to physical activity. A physically literate individual is expected to be cognitively knowledgeable, physically competent, and mentally motivated for a physically active life throughout the lifespan. The advancement of technology in recent years, especially those in active video games(AVGs), seems to have allowed the mind-body integrated physical activity accessible to children at all ages. This article reviews findings from research and critique research on AVGs in light with the theoretical and pedagogical tenets of physical literacy and, on the basis of the review, elaborates the potential that AVGs could contribute to enhancing children's physical literacy. 展开更多

The rational design of urban public space has more and more attention of the community; in the end, people need public spaces of an active exploration and attempt. Through human experience of urban public space, the design of public space in the city questioned the rationality, emphasized the human behavior activities on public space design requirements, and emphasized the place of people, human behavior activities, and the activities of the Trinity design ideas.
