Abstract

As a shot of shot-put is heavy and the flying velocity of the shot is small, the influence of air resistance on the trajectory of the shot is negligible. Thus, we can easily calculate the trajectory and the projected range of the shot from the position and the velocity of the shot just after it is released from the hand of a shot-putter. By measuring the 3D movement and trajectory of each part of the shot- putter's body. The time dependence of the force given to the shot is obtained and the capacity for locomotion of the shot-putter can be estimated quantitatively. In this paper, high-speed photography recording of shot-put is performed on the student shot-putters of Tokai University and their playing ability is estimated from the time dependence of the force given to the shot obtained by analyzing the recorded images.
