KINEMATIC ANALYSIS OF THE RUN UP FINAL STRIDE AND TAKE-OFF TECHNIQUE IN CHINESE FEMALE FOSBURY FLOP JUMPERS

摘要

Horizontal velocity of CG of the Chinese jumpers was smaller than those of the international elite jumpers through FT to FF. The range of knee extension was insufficient in the Chinese jumpers. However, the Chinese jumpers' techniques from FL to TT were superior to international elite players since the length of the final stride of Chinese jumpers was shorter than international jumpers. The average vertical velocity of CG of the Chinese jumpers was smaller. The heights of their CG and the angular velocity of internal trunk tilt at the instant of take-off leg leaves the grounds were small than international elite jumpers. These factors will affect the distance between CG and bar when jumpers reach their highest point.
