Heart of the athlete

The preparticipation sports examination for high school and college athletes

The PSE can be used as a tool to allow athletes to participate safely in sports. The goal of the PSE is not to disqualify athletes but to ensure that their participation in sports does not unnecessarily increase their risk of injury. The PSE is most effectively conducted by the station method with multiple examiners, one of whom should have specialty training in musculoskeletal disorders. The examination should be conducted 6 weeks prior to the beginning of the season and at the beginning of each new level of competition, unless directed differently by local laws. The correct use of the PSE should screen for signs and symptoms of pathological states that may lead to a nontraumatic death while participating in sports. An effective musculoskeletal examination should detect any postinjury deficits that may lead to subsequent reinjury later in the season. It is our hope that a PSE, based on the literature, can be used to prevent some of the nontraumatic deaths and musculoskeletal injury associated with sports participation.

The athlete's heart: is big beautiful?

Development of the concept of "athlete's heart" is traced through early clinical and radiographic studies to modern echocardiography and magnetic resonance imaging. It is noted that the lower limits of criteria for the diagnosis of a "pathological" enlargement of the heart have frequently been revised in an upward direction, as the prevalence of large hearts has been recognised in both endurance and power sports competitors who are in good health. Belief that hypertrophic cardiomyopathy is the commonest cause of sports related death in young adults is traced to weak diagnostic criteria and frequent republication of a very small group of cases. Although the existence of a congenital myocardial dystrophy is now well established, this condition is extremely rare, and has no particular predilection for athletes. Genetically based screening tests may become available in the future, but the exclusion of young adults from sports participation on echocardiographic criteria appears costly and ineffective. For most people, the development of a large heart is not a pathological sign--rather, it is a desirable outcome that will enhance performance on the sports field, and will allow longer independence in old age.
