The purpose of this study was to investigate the kinetic factors of the straight, hook, curve of throwing motions in bowling according to the three pitches of male bowlers and to provide the basic data of consistent throwing motion techniques and instructions. Six male bowlers in B city were participated in this experiment and their pictures were taken with 3-D image analysis. All data were presented by analyzing the mean time of each phase, the range of angle and gravity, the pattern of throwing, the mean of velocity during release motion, and the angular momentum. The results were as follows:
In the male bowlers’ throwing motions ‘Of three pitching speed - straight, hook, and curve, for the at the release, curve was rapid than the straight or the hook. In the male bowlers’ throwing motions of three - straight, hook, and curve, for the angular momentum by event, the antebrachial angular momentum tended to increase gradually over the angular momentum of the trunk of body and humerus. In conclusion, in the male bowlers’ throwing motions of three pitches - straight, hook, and curve balls, it is crucial to secure the stability leftward and rightward in the movement range of the center of gravity, to preserve the low posture upward and downward right before the release point, and to increase the antebrachial angular momentum.
