Abstract
The purpose of this study was to analyze kinematic quantitative factors required to Backhand power drive in table tennis through 3-D analysis. Four national table tennis players participated in this study. The results of the study were as follows.
1) COM(Center of mass) of subject moved to forward after back swing. It allows more power and spin to the ball during impact. Low COM during back swing is considered to increase stability and allow greater accuracy.
2) Elapsed time for each phase uses reaction force of opponent's ball. Effective back swing needs to be short and simple.
3) Resultant velocity of racket-head was the fastest at impact, it generates a greater impulse allowing more speed and spin of the ball.
4) Right knee joint angle stayed low from address to back swing position. With the beginning of forwarding movement, knee joint angle started to increase. It becomes upright posture at impact and COM shifted to the forward leg. To propel body into forward and up position, knee angle kept increasing.
