In this study, we examined the utility of self-determination theory (Ryan & Deci, 2002) as a framework for understanding the antecedents of athlete burnout in elite New Zealand rugby union players (n=133). Perceptions of competence, autonomy, and relatedness (i.e. basic psychological needs) were hypothesized to be negatively related to burnout scores, while players classified as "high-burnouts"...

the aim of this study was to determine the effect of two kinds of resistance training and one period of detraining on serum levels of myostatin, cortisol, testosterone and muscle strength of non-athlete men. for this purpose, 34 non-athlete men (age 33.35+2.8 yr) were divided into three groups: experimental a (4 sessions of training per week), experimental b (3 sessions of training per week) an...

the aim of this study was to compare the effect of a session of aerobic and anaerobic exercise on changes of iga/salivary total protein ratio in non-athlete girls. 36 non-athlete girls were randomly divided into three groups: anaerobic (n =12) with mean age of 23±1.91 years, aerobic (n =12) with mean age of 21±1.45 years and the control group (n =12) with mean age 23.25±2.09 years. salivary sam...

Perfectionism has been identified as an antecedent of athlete burnout. However, to date, researchers examining the relationship between perfectionism and athlete burnout have measured perfectionism at a trait level. The work of Flett and colleagues (Flett, Hewitt, Blankstein, & Gray, 1998) suggests that perfectionism can also be assessed in terms of individual differences in the frequency with ...

BACKGROUND Previous reviews of tae kwon do (TKD) tournaments have documented injury rates of 25/1000 to 12.7/100 athlete exposures. Most injuries have been reported to be to the head and the neck and are occasionally very serious. Many of these studies involved high level TKD competitions with minimal safety precautions. Recently, safety measures have been implemented in many TKD competitions. ...
