Research Abstract

The purpose of this study was investigate relationship between technical factor (braking force and knee joint angle of non-support leg) and sprinting velocity by cross sectional study and longitudinal study. We use 12thmale athletes in this cross sectional study and 8thmale athletes who difference performance level in this longitudinal study. And in longitudinal study we conducted measurements at frequency as two times / year and total four times.The main results were as follows. Centrifugal force of non-support leg C.G. is about 300N, this is 1/5 of vertical force (about 1500N). These results suggest that Centrifugal force of non-support leg C.G.is have a big influence on ground reaction force.
