Ground reaction force of rotational shot put - case study

The purpose of this study was to investigate the kinetic variables of two legs during rotational shot put. Three male rotational shot putters served as subjects. Two force platforms were synchronized to collect the data. The kinetic variables of right leg which had the trend of decrease with better performance were the maximal vertical force, rate of force development of maximal propulsive force, impulse of horizontal and vertical force during braking phase, total impulse of horizontal and vertical force. The kinetic variables of left leg which had the trend of increase with better performance were the total impulse of vertical and horizontal force. The smaller braking and greater propulsive time of the right leg, and the greater braking and vertical thrust of the left leg would helpful for better performances.
