This meta-analysis investigated the maturation-related pattern of adaptations to resistance training in boy athletes. We included studies examining the effects of 4–16-week resistance training programmes in healthy boy athletes aged 10–18 years. Pooled estimates of effect size for change in strength across all studies (n = 19) were calculated using the inverse–variance random effects model for meta-analyses. Estimates were also calculated for groups based on likely biological maturity status (“before”, “during” and “after” peak height velocity). Using the standardised mean difference, resistance training increased strength across all groups (effect size = 0.98, [CI: 0.70–1.27]). Strength gains were larger during (1.11 [0.67–1.54]) and after (1.01 [0.56–1.46]) peak height velocity than before (0.5 [?0.06–1.07]). Adaptations to resistance training are greater in adolescent boys during or after peak height velocity. These findings should help coaches to optimise the timing of training programmes that are designed to improve strength in boy athletes. 相似文献

Official rankings are the most common measure of success in professional women’s tennis. Despite their importance for earning potential and tournament seeding, little is known about ranking trajectories of female players and their influence on career success. Our objective was to conduct a comprehensive study of the career progression of elite female tennis talent. The study examined the ranking trajectories of the top 250 female professionals between 1990 and 2015. Using regression modelling of yearly peak rankings, we found a strong association between the shape of the ranking trajectory and the highest career ranking earned. Players with the highest career peak ranking were the youngest when first ranked. For example, top 10 players were first ranked at age 15.5 years (99% CI = 14.8–15.9), 1.2 years (99% CI = 0.8–1.5) earlier than top 51–100 players. Top 10 players were also ranked in the top 100 longer than other players, holding a top 100 ranking until a mean age of 29.0 years (99% CI = 27.8–30.3) compared with age 24.4 years (99% CI = 23.7–25.2) for top 51–100 players. Ranking trajectories were more distinct with respect to player age than years from first ranking. The present study’s findings will be instructive for players, coaches, and administrators in setting goals and assessing athlete development in women’s tennis. 相似文献

ABSTRACT Models of positive youth development suggest that athletes may be influenced by parent education programmes; however, there is little research examining the impact of such programmes on athlete outcomes. This study examined the impact of the Respect in Sport Parent Program on athlete outcomes among minor hockey players over three years. This study consisted of cross-sectional and longitudinal online surveys measuring athletes’ positive and negative developmental experiences, prosocial and antisocial behaviours, parental support and pressure, and sport enjoyment and commitment. Athletes completed at least one online survey during the study period (N = 366; 84.2% males; 14–19 years of age; M = 15.4 years), and 83 athletes completed multiple surveys for longitudinal analyses. Cross-sectional results comparing athletes in leagues adopting the programme at different time points indicated significant differences in prosocial behaviours towards teammates. Multilevel longitudinal analyses revealed improvements in athletes’ antisocial behaviours towards opponents, initiative, goal setting, and cognitive skills over time, regardless of whether they were in a league that implemented the programme. However, athletes in leagues that implemented the programme during the study reported greater improvements in antisocial behaviours towards opponents, and there were trends with respect to improved personal and social skills. These findings provide suggestions to improve the delivery and impact of parent education programmes in youth sport. 相似文献

The coaching competency research has demonstrated the role of coaching efficacy and coaching behaviors on various athlete outcomes. However, athlete perceptions of these relationships and how they affect performance are less understood. Purpose: This study examined if coaching efficacy is predictive of player perceptions of coaches’ leadership styles, team atmosphere, and team performance in a soccer season. Method: Fifteen male premier league soccer coaches (Mage = 45.27, SD = 6.07) and 226 players (Mage = 25.66, SD = 3.96) from Botswana participated in the study. All participants completed a background information questionnaire. Coaches completed the Coaching Efficacy Scale. Players rated their coaches’ leadership styles using the Revised Leadership Scale for Sports as well as team atmosphere. Team performance was based on position in the league log and player ratings of the teams’ performance. Results: Findings showed that coaches’ self-ratings on technique efficacy predicted player perceptions of the coaches’ use of all six leadership styles. Game strategy efficacy predicted higher team atmosphere and team performance. Motivation efficacy was not significantly associated with player perceptions of the coaches’ use of any of the leadership styles, while character building efficacy was negatively associated with the various leadership styles. Conclusion: Findings provide support to previous research evidence linking higher coaching efficacy, leadership styles, and team outcomes. The study expands the emergent research within the coaching competency literature that examines player perceptions of coaches’ behaviors and leadership styles. 相似文献

Structured talent identification and development, it has been argued, is one of the foundations of international sporting success and many modern elite sport systems have applied normative talent development (TD) models. The success of Norwegian handball, however, is based on an alternative approach to TD. Norwegian handball is characterized by a heterarchical organizational structure in which several key actors function highly autonomously. The aim of this article is three-fold: (a) to describe the organization of TD in Norwegian handball, (b) to identify how the inherent organizational characteristics of Norwegian handball have influenced the TD processes used and (c) to discuss if contemporary TD models provide an adequate conceptualization of the model used in Norwegian handball. This case study includes three units of analysis: (i) the overall organizational structure of Norwegian handball, (ii) the characteristics of the key actors involved and (iii) the inter-communication and collaborations of the key actors. The data sources were (a) documents and (b) interviews with 11 key informants. The informants were selected strategically to represent experienced coaches and professionals from multiple organizational units. The National Handball Federation uses a broad-based model for TD: 23% of male handball players and 15% of female handball players from the age of 13–17 years participate in regional-level initiatives in addition to practising daily in community-based volunteer sport clubs and sport schools. Findings reveal that the broad base of TD initiatives creates multiple access points to the talent pipeline for adolescents. However, because the heterarchical structure involves many actors, the unintended consequences are often related to (im)properly managing training and competition loads. There is a need therefore for well-developed coordination mechanisms and good communication between the key actors involved. 相似文献

AbstractMost countries across the world are facing one problem: how to provide support to retired athletes and help them in re-employment. Different countries have different solutions. Study of the retirement and re-employment of professional athletes in China will help us to understand the differences between it and other countries in dealing with this issue. It will also reveal how China’s elite sport system works and how the government played its part in managing and supporting the athletes. This paper studies the formation and implementation of government policies in relation to the re-employment of retired athletes and points out that the Chinese Government plays an important role in providing financial and human resource support for them. However, the policies have also had some shortcomings. For example, the government takes too much of the burden. Only elite athletes who won medals at important national and international sporting events could get solid support after retirement and most of the athletes who failed to make it to the top were neglected by the government. 相似文献

AbstractWithin the Chinese national sport system, the government provides resources and funding to train athletes from a young age to become high-performance competitors. Though athletes are well supported to excel in their sport, during their years of intense physical training, athletes generally receive little to no formal education to prepare them for life outside of sport. The sacrifice of forgoing formal education to compete in elite level sport is not uncommon for athletes within centralized sporting systems and has been widely documented; however, there is little research that focuses on the impact of the team’s educational systems from the perspective of the athletes. To add to the growing body of research in this area, the authors utilized in-depth interviews to examine professional wushu athletes’ education experiences whilst training on their team. Thematic analysis of the findings revealed that athletes who committed themselves to sport training in the Chinese national system had to negotiate a number of factors related to time, motivation, social influences, and resources when it came to education and academia. Findings highlight the ways in which these athletes experience and come to terms with limited academic opportunities, preparation and support from their team and the training environment. 相似文献

Given that research outside of sport and exercise has found that stigma may cause severe consequences (e.g. depression), it is important to explore the concept in regard to its connection to socio-cultural issues in the development and persistence of stigmatisation in sporting contexts. Analytic autoethnography and Goffman’s theory of stigma was used to explore one female swimmer’s experiences of ‘enacted’ and ‘felt’ competitive performance stigma occurring in elite swimming and a masters swimming context. Competitive performance stigma has not been conceptualised or explored as a stigma type in sport research, however through the presentation and analysis of two vignettes and the use of Goffman, this is achieved. The social agents that contributed to both ‘enacted’ and ‘felt’ competitive performance stigma and the consequences/effects (e.g. withdrawal from sport, feelings of shame) for this swimmer are highlighted. Our analysis further highlights the role of particular cultural insiders (e.g. coaches, team managers and other swimmers) in the reproduction of competitive performance stigma through acts of labelling, discrimination and social isolation. These acts positioned the female swimmer as an ‘outsider’ because of her competitive performance which in turn led to her withdrawal from these two sporting contexts highlighting the implications for recipients of stigmatisation. 相似文献

During the past several decades, South Korea has gained tremendous international recognition by achieving an excellent performance in a variety of international sport competitions and hosting numerous mega-sporting events. Although success in elite sport (i.e. Development of Sport approach) has contributed to making South Korea one of the sport powerhouses in the world, South Korea has paid very little attention to the role that sport can play as a tool for social and personal development (i.e. Development through Sport approach). Similarly, scholars also paid little attention to the ‘development through sport’ approach in South Korea while predominantly focusing their attention in taking the ‘development of sport’ approach. In recent years, however, the South Korean government has begun to show interest in the ‘development through sport’ approach to become a truly advanced sporting nation. Thus, the purpose of this paper is to explore how South Korea's paradigm in sport has historically shifted from ‘development of sport’ to ‘development through sport’ in its socio-political context. 相似文献
