The authors performed physical component and aerobic and anaerobic capacity tests on 117 second string athletes (60 males and 57 females) of such three events as sprint-ing, bicycle racing and fencing, and revealed the following findings: basically there is a medium or high degree cor-relation between the body weight, muscle, protein and anaerobic capacity index of male and female athletes of the three events; there is a low degree correlation between the athlete’s total muscle and protein weight, body weight, and blood lactic acid; there is a low degree negative correlation between the body fat and anaerobic capacity related indexes of the athletes of the three events. The said findings indicate that various physical components have a close relation with physical capacities; however, since different events have different characteristics, their correlations are significantly different.
