 note = {The purpose of this study was to compare the shot put motion among male athletes with various competing levels. The subjects were six world top putters (group W) , six Japanese top putters (group J) , and five university student putters (group S) . The putting motions were filmed with high-speed cinematography and analyzed to obtain release parameters (initial velocity, release angle, release height, release length) and force and power provided to the put during putting motion. The mean record of analyzed trials was 20.56m. 16.29m, and 13.63m for group W, group J. and group S, respectively. Initial velocity of the shot (average: 13.77 m/s (W), 11.76m/s (J), and 11.03 m/s (S)) correlated significantly with the putting distance, and had the greatest influence on the record among the release parameters. Though release angle had less influence on the putting distance, the world top athletes put the shot with higher release angle (38.8 deg) compared to the Japanese top (35.3 deg) and student (35.6 deg) putters. Both mean force and mean power provided to the shot during putting motion was greater for group J (331 N, 2415 W) compared to group W (321 N, 2315 W) and group S (291 N, 2195 W). One of the reasons of this tendency was that the duration of acceleration phase of the putting motion of group J (0.24 s) was the shortest compared to the other groups (W: 0.30 s, S: 0.26 s). These results may be considered to be related to the athletes physique. (This study is part of the activities of the Biomechanics Research Project Team of the Japan Amateur Athletic Federation.)},
