| Research Abstract |
In this study, we analyzed the shots of actual games in table tennis competition. First of all, we computed the ball speed, and found that when hit with maximum speed the ball could go across the table within 0.1 sec, which is as same as the limiting value of total body reaction time of human. Further we computed the theoretical spin-free ball shot trajectory, and clarified the functions of ball spin on shot trajectory.
