The need to promote higher habitual MVPA engagement amongst children active in the youth sport context has therefore been underlined. Framed by self-determination theory, the aim of the present study was to examine the implications of the motivational climate created in youth sport, for children's daily engagement in MVPA and associated adiposity. Specifically, we sought to test a motivational sequence in which children's perceptions of an empowering coach-created motivational climate were related to autonomous and controlled motivation, which in turn predicted sport-related enjoyment. Finally, enjoyment was assumed to predict accelerometer assessed daily MVPA and, following this, adiposity.Methods: Male and female youth sport participants aged 9–16 years(n = 112) completed multi-section questionnaires assessing their perceptions of the motivational climate created in youth sport(i.e., autonomy supportive, task involving, socially supportive), autonomous and controlled motivation, and sport-related enjoyment. Daily MVPA engagement was determined via 7 days of accelerometry. Percent body fat(BF%) was estimated using bio-electrical impedance analysis.Results: Path analysis revealed perceptions of an empowering motivational climate positively predicted players' autonomous motivation, and in turn, sport-related enjoyment. Enjoyment was also significantly negatively related to players' BF%, via a positive association with daily MVPA.Conclusion: Fostering more empowering youth sport environments may hold implications for the prevention of excess adiposity, through encouraging higher habitual MVPA engagement. Findings may inform the optimal design of youth sport settings for MVPA promotion, and contribute towards associated healthy weight maintenance amongst youth active in this context. Longitudinal and intervention studies are required to confirm these results.展开更多

The Youth Experiences Scale for Sport (YES-S) [1], is a five-factor measure of positive youth outcomes specifically designed for the sport context. The YES-S is a promising instrument that fills an important niche in PYD research, and MacDonald et al. provided support for many of its psychometric properties. However, the factor structure of the scale is currently based on an exploratory factor analysis and has not yet been subjected to a confirmatory factor analysis (CFA). The present study was designed to confirm the five-factor structure of the YES-S. A sample of 350 youth sport athletes (196 male, 153 female) completed the YES-S. A CFA showed that a modified version of the five-factor YES-S had excellent fit of the model to the data. An analysis of invariance showed no differences in responses in terms of gender. It is concluded that this short-form YES-S offers excellent psychometric properties while retaining the original factor structure of the YES-S. The results offer further support for the validity of the factor structure of the YES-S while providing a shorter version of the scale, which may be appealing for research with younger sport participants.展开更多

Its existence in youth sports like soccer is well established. Why it occurs has not been identified, however, one thought is that older players, generally taller and heavier, are thought to improve the team＇s chances of winning. To test this assumption, birth dates and match outcome were correlated to see if teams with the oldest mean age had a systematic advantage against teams with younger mean ages. Methods： Player birth dates and team records （n = 5943 players on 371 teams; both genders; U11-U16） were obtained from the North Carolina Youth Soccer Association for the highest level of statewide youth competition. Results： The presence of an RAE was demonstrated with significant oversampling from players born in the I st vs. the 4th quarter （overall： 29.6% vs. 20.9% respectively, p 〈 0.0001）. Mean team age was regressed on match outcomes （winning %, points/match, points/goal, and goals for, against, and goal difference）, but there was no evidence of any systematic influence of mean team age and match outcomes, except possibly in U11 males. Conclusion： Selecting players based on physical maturity （and subsequently, on age） does not appear to have any systematic influence on match outcome or season record in youth soccer suggesting that the selection process should be focused on player ability and not on physical maturation.展开更多

This article looks at four specific youth coaching styles and how three of the coaching approaches evoke poor coping skills and weaken resiliency behaviors in children and adolescents. Problem: The authors present an overview of how youth coaching styles contribute to unconscious powerful Transactional Analysis (TA) life scripts that can negatively impact children into adulthood. The authors examine four unique coaching styles and their effect on the Winner, Loser, and Non-Winner life scripts found in the Transactional Analysis literature. Methods: While the literature is quite limited on this topic, themes and inferences were drawn from previously published professional literature. Results: Findings reflect how specific coaching styles may evoke winner, loser and non-winner scripts in young athletes, and that these scripts can influence children later in life. Conclusion: The authors recommend using the positive-structured coaching style in youth sports to promote resiliency, fun, and improved coping skills in youth playing sports.展开更多
