Despite similarities between the PSCs facilitative of youth athletes’ development and elite athletic performance to be expected, it is important to distinguish the psychological needs of adult and youth athlete populations. Particularly, experts have

Recent research has used self-determination theory to examine athlete burnout among adults. However, there is a dearth of theory-driven research investigating burnout among young athletes, particularly as it pertains to its sociological influences. With research suggesting that motives for sport (dis)continuation vary among athletes of different ages, this study assessed the utility of self-determination theory (SDT) and Coakley’s model for youth burnout while examining developmental differences. Participants included swimmers of ages 7–17. Analyses revealed a model that approached adequate ft indices and accounted for 70% of the burnout variance. Results supported utilizing these theories to understand youth burnout while accounting for developmental differences.

The purpose of this study was to examine predictors of social physique anxiety (SPA). SPA, self-esteem, body-esteem, public body consciousness (PBC) and percent body fat (%BF) were assessed with elite female youth athletes (̲N=68) competing in either figure skating, soccer or gymnastics. Stepwise multiple regression analyses, controlling for BF%, accounted for 59% of the variance in SPA. Self-esteem entered first, after BF%, followed by body-esteem and PBC. The psychological variables accounted for 57% of the variance with self-esteem contributing the most (R square change = 45%). Contrary to previous research, BF% did not significantly contribute to SPA. Additionally, a MANOVA and follow-up ANOVA and Scheffe’s tests revealed significant sport differences among SPA, self-esteem, and body-esteem.

To understand the mechanisms for the effects of resistance training on functional parameters, and to assess the injury risk of the involved tissues, it is necessary to examine the underlying morphological and structural changes of the respective tissues.
The presented information on physiological adaptations have been deduced from cross-sectional studies comparing youth athletes with controls and children with adults as well as from longitudinal studies examining the effects of resistance training in untrained children and adolescents and in youth athletes.
The evidence indicates, that training induced changes in motor performance rely partly on enhanced neuromuscular control, and partly on morphological adaptation of muscles and tendons, such as changes in muscle, muscle fiber and tendon cross-sectional area, muscle composition, and tendon material properties, with the bone also adapting by increasing bone mineral content and cortical area.
Although the training induced adaptations of the investigated tissues follows similar principles in children as in adults, the magnitude of the adaptive response appears to be more subtle. As studies investigating physiological adaptation in youth athletes are sparse, more research in this area is warranted to elucidate the specific physiological stimulus-response relationship necessary for effective training programs and injury prevention.
