휠체어 볼링 투구 동작의 운동학적 특성분석

The purpose of this study is to provide basic data for improving the performance of wheelchair bowlers through the kinematical analysis of wheelchair bowling. The following conclusions were obtained based on the results of this study. First, the total time showed 0.90 s, with the longest time in the backswing interval. Second, the COM almost did not change in all X, Y, Z axis. Third, the resultant velocity of the ball during the release showed an average of 4.96 m / s. Fourth, the upper arm and torso were apart by an average 50.7° during the release; and the inner and outer upper arm rotation angle was an average of -78.84° at the top of the backswing. Fifth, the angle of elbow was flexed after the top of backswing； the angle of the wrist flexed after push away. Sixth, the body was bent forward most during the release; the rotation of the shoulder was the most at the backswing top in the clockwise direction. Seventh, for the tilt angle of the shoulder, the tilted shoulder went up again from the address to the backswing top, tilted again during the release after the backswing top, and went up again during the follow-through. Wheelchair Bowling for the future on the basis of this study, suggestions need more study and research for the development of a dedicated wheelchair, wheelchair bowling performance enhancement w ill be made.
