Subjects were 24 male shot putters with glide technique during finals of three international athletic meets. The putting motions were recorded and analyzed using three dimensional motion analysis procedures. The subjects were divided into three groups according to the record utilized for the analysis. The putters of the group A (average record: 20.13 m) tended to be taller and heavier compared to those of the group B (18.01 m) and C (16.13 m). Initial velocity of the shot correlated significantly with the putting distance, and had the greatest influence on the record among the release parameters. There was no statistical significant difference in velocity of body center of gravity among the groups neither in glide phase nor at release instant. The shot was accelerated abruptly in thrust phase. The peak force and power exerted on the shot correlated strongly with the putting distance. At the release instant, there was no significant difference among the groups in any kinematic variables obtained. At the end of the glide phase, support leg knee was more flexed and shoulder was more twisted against the putting direction in group A compared to other two groups. The most important concept for successful performances in shot putting would be that the athletes should take up a good body position suitable for a powerful thrusting phase which will allow for the highest possible velocity of release.}, pages = {25--32}, title = {Comparison of shot put motion among male athletes with various competing levels}, volume = {22}, year = {1999} }
