In an earlier paper (Khosla, 1968) it was observed that winning athletes (gold medallists) in many of the Olympic events at the Tokyo Olympiad in 1964 were much above the average heights of all participants in their events. In contrast, it was noted that competitors in a few events (boxing, wrestling, judo, and weightlifting) are matched on rigid weight standards, and because weight and height ...

Several relatively uncommon, but important cardiovascular diseases are associated with increased risk for acute cardiac events during exercise (including sudden death), such as hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM), arrhythmogenic right ventricular cardiomyopathy (ARVC) and myo-pericarditis. Practising cardiologists are frequently asked to advise on exercise programmes...

In this study, we used the trans-contextual model of motivation (TCM) to examine the effect of Sport Education (SE) on students' participation in a voluntary lunch recess sport club. A total of 192 participants (ages 9-14 years) completed measures of the TCM constructs before and after a 12-week SE intervention period. Participants had the opportunity to participate in weekly, voluntary lunch r...

1 Impairment-based evaluation has, until recently, been the mainstay of orthopaedic 2 research in anterior cruciate ligament (ACL) reconstruction. However, participation-3 based outcomes, in particular returning to sport, have lately garnered increased 4 research attention. This is important because returning to sport is typically a main 5 concern of injured athletes. Recent meta-analyses have ...
