A substantial amount of evidence suggests that collegiate and elite athletes involved in weight-sensitive sports are at greater risk of developing eating disorders (EDs) than the general population. With the limited effectiveness of treatment for EDs, prevention of EDs has been broadly considered in the literature. The present paper reviewed the existing literature on ED prevention programmes for athletes in order to determine the current status of prevention programmes and recommend future directions. The available literature suggests that selective, primary interventions with multiple targets and an interactive multimodal approach appear most effective. Current challenges in the field, including lack of longitudinal research, hesitation by the sport community to be involved in ED research and poor cross-field communication and collaboration, are also explored. The lack of dissemination of evidence-based prevention programmes and the simultaneous promotion of prevention programmes that have not yet been empirically examined are also discussed. Based on these observations future directions are recommended.  相似文献

Testing is one of the important tasks in any multi-step sport programme. In most ball games, coaches assess motor, physical and technical skills on a regular basis in early stages of talent identification in order to further athletes’ development. The purpose of the study was to investigate anthropometric variables and vertical jump heights as a free throw effectiveness predictor in water-polo players of different age groups. Two hundred and thirty-six young (10–18 years) male water-polo players partitioned into three age groups underwent anthropometric variables’ measures and squat- and countermovement-jump tests, and performed water-polo free throws. Anthropometric variables, vertical jump heights and throw speed – as a proxy for free throw effectiveness – resulted different over age groups. Particularly, throw speed changed from 9.28 to 13.70 m · s?1 (+48%) from younger to older players. A multiple-regression model indicated that body height, squat-jump height and throw time together explain 52% of variance of throw speed. In conclusion, tall height, high lower limb power and throwing quickness appeared to be relevant determinants for effective free throws. Such indications can help coaches during talent identification and development processes, even by means of novel training strategies. Further research is needed over different maturity statuses.  相似文献

Dribbling speed in soccer is considered critical to the outcome of the game and can assist in the talent identification process. However, little is known about the biomechanics of this skill. By means of a motion capture system, we aimed to quantitatively investigate the determinants of effective dribbling skill in a group of 10 Under-13 sub-elite players, divided by the median-split technique according to their dribbling test time (faster and slower groups). Foot-ball contacts cadence, centre of mass (CoM), ranges of motion (RoM), velocity and acceleration, as well as stride length, cadence and variability were computed. Hip and knee joint RoMs were also considered. Faster players, as compared to slower players, showed a 30% higher foot-ball cadence (3.0 ± 0.1 vs. 2.3 ± 0.2 contacts · s?1, < 0.01); reduced CoM mediolateral (0.91 ± 0.05 vs. 1.14 ± 0.16 m, < 0.05) and vertical (0.19 ± 0.01 vs. 0.25 ± 0.03 m, < 0.05) RoMs; higher right stride cadence (+20%, < 0.05) with lower variability (< 0.05); reduced hip and knee flexion RoMs (< 0.05). In conclusion, faster players are able to run with the ball through a shorter path in a more economical way. To effectively develop dribbling skill, coaches are encouraged to design specific practices where high stride frequency and narrow run trajectories are required.  相似文献

Abstract

Studies on the development of Olympic Solidarity as a tool of the International Olympic Committee (IOC) to enable National Olympic Committees of developing countries access to resources and influence in the Olympic Movement exist. However, historical scholarship has relatively neglected the development of aid programs by International Federations to explain how they made use of resources to gain influence in international sport politics. Based on extensive multi-national and multi-lingual archival research in the archives of the International Association of Athletics Federation (IAAF) and the German Sport University Cologne, this article explores the establishment and development of the IAAF‘s Technical Aid Program, which had been installed in 1974. Referencing a large amount of previously unknown protocols and written correspondence, the paper critically discusses the IAAF‘s development activities in light of two parallel occurring processes that shaped the federation’s character in the 1970s and 1980s decisively: its increasing commercialization and its path towards democratization in its voting system. It is argued that the IAAF development programs served as a tool to enforce commercial and sport political interests whilst the nature of support remained without clear guidance until the mid-1980s.  相似文献

Abstract

This paper explores the migration of female basketball players from Taiwan to China. Governance theory is adopted as the framework in this study to analyze the phenomenon of players’ migration and to understand how it was shaped over the years. The empirical work draws on a qualitative approach, which is based on a review of documentary materials and semi-structured interviews; coding and analysis were undertaken with a content analysis approach in order to investigate the decision-making processes and their consequences for the players’ migration. The feature of systematic governance for the development of women’s basketball has been revealed in this study. Stakeholders with personal interests caused the downturn of women’s basketball development in Taiwan, and it eventually led to the players’ migration abroad. Through the lens of governance theory, it has been revealed that a number of factors – namely, political, financial, personal, socio-economic, and cultural – all intertwine with one another dynamically to influence the female players’ decision to move abroad. This finding broadens the scope for the research of Taiwanese athletes’ migration to China, extending the focus from only business or industry to other aspects, thereby highlighting the fact that the subject is more complex than previously understood.  相似文献

Abstract

This paper explores multiple and complex relationships between football (soccer), politics, and the economy in postcolonial Zambia. Based on archival and oral sources collected in Zambia, the paper argues that President Frederick Chiluba’s government failed to support football development when it came into power in 1991 because it was elected on a platform of liberalizing the collapsing national economy. Chiluba privatized state-owned companies that were sponsoring the game resulting in the plummeting of the local standards and migration of talented footballers abroad in search of better livelihoods. Furthermore, the paper argues that while the exodus of talented footballers led to the deterioration of the standards of the local league, their transnational experience boosted the performance of the Zambia national football team. This led to the emergence of one of the best national teams the country has ever had. Unfortunately, this particular team perished in the Gabon air disaster in 1993 following the government’s disinvestment in the game. However, a few months after the disaster, the country managed to rebuild a national football team, which emerged as runners up to Nigeria in the 1994 African Cup of Nations final as a result of a large pool of local and foreign-based football players.  相似文献

我国民事诉讼理论目前以"二元论"作为通说,由于在实践中存在着一些误区,如把诉权视为审判权的产物、无视当事人的主体地位等,造成一些侵犯当事人诉权的现象.这需要从理论上对诉权做出准确定性,建立起诉权人权化的思想,真正重视当事人及其诉权,从而实现从法官公正到法律制度的公正.  相似文献

Abstract

Canadians have been involved in every edition of the Pan-American Games since they were inaugurated in Buenos Aires in 1951. That participation has provided thousands of Canadian athletes, coaches, and officials memorable international experiences. But the focus of Canadian involvement with the Pan-Ams has been the staging of games as a strategy for city building, city branding, and infrastructural investment. This paper examines the Pan-American Games of Winnipeg in 1967 and 1999 and Toronto 2015 as exemplars of that strategy. It argues that with the successes of those games, major games hosting has become virtually an article of faith of Canadian sport policy.  相似文献
