Abstract

Untrained males (n = 52) and females (n = 83) were measured on the standard Margaria-Kalamen anaerobic power test. Velocitiy in the last 4 meters of the acceleration zone was measured with photoelectric cells. Body composition was estimated from skinfolds. Faster acceleration velocity was generally associated with faster vertical velocity. The correlation between acceleration velocity and absolute power, however, was low. When the effect of body weight was removed, the relationships between power and acceleration velocity and vertical velocity rose significantly. In addition, removing the effect of body weight revealed the negative effect of fat on power production. While stair running skill may be an important component of the Margaria-Kalamen test, the test may also reflect body compositon differences among individuals. Verf.-Referat
