Abstract

Twenty-five athletes competing in a triathlon, an endurance competition, were studied to determine the relationship of sustained muscle exertion with myoglobinemia and clinical rhabdomyolysis. Of 24 athletes who completed the event, each individual demonstrated a dramatic rise and fall in serum myoglobin over a 24 hour period, with an average peak level of 842 ng/ml. While all subjects exhibited symptoms of myalgia after exertion, none required hospitalization. A significant correlation was demonstrated with average serum myoglobin and finishing time and postexercise temperature: Appropriate training of individuals, whether athletes or military recruits, appears to be an important factor in reducing myoglobinemia. Exercise-induced myoglobinemia appears to be dependent on intensity of athletic performance, measured as a function of time, distance, and activity performed. The athletes whofinished first had the highest levels of myoglobinemia. Verf.-Referat
