BACKGROUND Sport specialization is a strategy to acquire superior sport performance in 1 sport but is associated with increased injury risk. Currently, the degree of high school specialization among Division I athletes is unknown. HYPOTHESIS College athletes will display increased rates of specialization as they progress through their high school careers. STUDY DESIGN Descriptive epidemiolo...

BACKGROUND Over the last two decades, morphological cardiac changes induced by athletic conditioning have been of great interest. Therefore, several studies have been orchestrated to delineate electrocardiography (ECG), echocardiography, and heart rate variability (HRV) findings in athletes. PURPOSE To assess the ECG, echocardiography, and HRV in a group of dynamic and static type athletes. ...

Sports psychologists have long believed that high levels of competitive state anxiety during competition are harmful, worsening performance and even leading to dropout. The instrument used for the study comprised of a 27-item Competitive State Anxiety Inventory–2 and The Psychological Performance Inventory which had been distributed during sport between universities competition. The sample cons...

Two field studies investigate the role of self in the tendency of athletes to engage in claimed handicapping strategies during training (anticipatively claiming that handicaps may interfere with their performance). Study 1 tested the relationship between trait self-esteem and athletes' engagement in claimed self-handicapping. As hypothesized, low physical self-esteem athletes claimed more handi...
