Since Hugh Montgomery discovered the first of what are now nearly 200 "fitness genes", together with rapid advances in human gene therapy, there is now a real prospect of the use of genes, genetic elements, and/or cells that have the capacity to enhance athletic performance (to paraphrase the World Anti-Doping Agency's definition of gene doping). This overview covers the main areas of interface between genetics and sport, attempts to provide a context against which gene doping may be viewed, and suggests a futuristic legitimate use of genomic (and possibly epigenetic) information in sport. 相似文献

The current study examined associations between physical education (PE) class enjoyment and sociodemographic, personal, and perceived school environment factors among early adolescent girls. Participants included 1,511 sixth-grade girls who completed baseline assessments for the Trial of Activity in Adolescent Girls, with 50% indicating they enjoyed PE class a lot. Variables positively associated with PE class enjoyment included physical activity level, perceived benefits of physical activity, self-efficacy for leisure time physical activity, and perceived school climate for girls' physical activity as influenced by teachers, while body mass index was inversely associated with PE class enjoyment. After adjusting for all variables in the model, PE class enjoyment was significantly greater in Blacks than in Whites. In model testing, with mutual adjustment for all variables, self-efficacy was the strongest correlate of PE class enjoyment, followed by perceived benefits, race/ethnicity, and teachers' support for girls' physical activity, as compared to boys, at school. The overall model explained 11% of the variance in PE class enjoyment. Findings suggest that efforts to enhance girls' self-efficacy and perceived benefits and to provide a supportive PE class environment that promotes gender equality can potentially increase PE class enjoyment among young girls. 相似文献

The aims of this study were to: (1) determine whether the number of pedometer counts recorded by adolescents differs according to the adiposity of the participant or location on the body; (2) assess the accuracy and reliability of pedometers during field activity; and (3) set adolescent pedometer-based physical activity targets. Seventy-eight 11- to 15-year-old Boy Scouts completed three types of activity: walking, fast walking and running. Each type was performed twice. Participants wore three pedometers and one activity monitor during all activities. Participants were divided into groups of normal weight (BMI < 85th percentile) and at risk of being overweight (BMI > or = 85th percentile). Intra-class correlations across the three activities indicated reliability (r = 0.51 - 0.92, P < 0.001). This conclusion was supported by narrow limits of agreement that were within a pre-set range that was practically meaningful. Multivariate analysis of covariance indicated adiposity group differences, but this difference was a function of the increased stature among the larger participants (P < 0.001). Ordinary least-squares regression models and multi-level regression models showed positive associations between the number of pedometer and activity monitor counts recorded by the three groups of participants during all activities (all P < 0.001). The mean number of counts recorded for all participants during the fast walk was 127 counts per minute. In conclusion, the pedometers provided an accurate assessment of adolescent physical activity, and a conservative estimate of 8000 pedometer counts in 60 min is equivalent to 60 min of moderate to vigorous physical activity. 相似文献

The purpose of this study was to expand our knowledge and increase our understanding of imagery use by athletes in sport-injury rehabilitation using a qualitative approach. The participants were 10 injured athletes who were receiving physiotherapy at the time they were interviewed. During the interviews, the athletes provided extensive information about their use of imagery during injury rehabilitation and it was clear that they believed imagery served cognitive, motivational and healing purposes in effectively rehabilitating an injury. Cognitive imagery was used to learn and properly perform the rehabilitation exercises. They employed motivational imagery for goal setting (e.g. imagined being fully recovered) and to enhance mental toughness, help maintain concentration and foster a positive attitude. Imagery was used to manage pain. The methods they employed for controlling pain included using imagery to practise dealing with expected pain, using imagery as a distraction, imagining the pain dispersing, and using imagery to block the pain. With respect to what they imaged (i.e. the content of their imagery), they employed both visual and kinaesthetic imagery and their images tended to be positive and accurate. It was concluded that the implementation of imagery alongside physical rehabilitation should enhance the rehabilitation experience and, therefore, facilitate the recovery rates of injured athletes. Moreover, it was recommended that those responsible for the treatment of injured athletes (e.g. medical doctors, physiotherapists) should understand the benefits of imagery in athletic injury rehabilitation, since it is these practitioners who are in the best position to encourage injured athletes to use imagery. 相似文献

The action sport industry is a high growth sector that attracts the lucrative Generation Y market. Although there is a growing body of literature that examines the characteristics and traits of the Generation Y market as consumers of action sports, little is known about the supply side of the action sports industry. This paper illustrates through the example of the skateboarding sport cluster, that this sector has evolved in an organic, almost chaotic manner very different to that of the mainstream sports industry. Entrepreneurs have taken advantage of the open system, the lack of formal boundaries and the risk loving nature of the market to grow the sector into a very profitable industry. The paper specifically illustrates the differences to mainstream sports in relation to provision of facilities, program development and pathways and the roles of suppliers, councils and program developers. 相似文献

This article reports on research conducted as part of the Primary Science Processes and Concept Exploration (space) Project. The background to, and orientation of, space is briefly described. Classroom‐based research into children's thinking about evaporation is reported. This work was conducted in close collaboration with teachers of the 5‐11 years age range with the intention of establishing the viability of the techniques for eliciting ideas and managing subsequent interventions within classrooms. Children's thinking in relation to three main evaporation phenomena are discussed. Ideas about evaporation were categorized by reference to notions of conservation, change of location and change of form of the water. 相似文献

Abstract Rural communities need rural teachers who can “ground” traditional school subjects in local realities and dilemmas and at the same time fashion instructional approaches consonant with larger intellectual, ethical, and social purposes. Such teachers are assets rather than burdens to their communities. Only such teachers can cultivate an ethic of responsibility for the health and vitality of the communities of which they and their students are critical components. This essay examines the role of the university in professionalizing rural teachers. It contends that narrowly utilitarian ends prevail in teacher education programs, and that, in the absence of a substantive definition of educations public purpose, this instrumentalism creates teachers who are ill‐prepared to contribute in meaningful ways to the intellectual life of the communities in which they work. Teacher preparation programs should abandon the instrumental focus. Programs that prepare rural teachers, in fact, confront unique challenges and opportunities to include three themes at their centers: Sustainability, Social Justice, and Democracy. 相似文献
