Nakano et. al diviced Physical Locomotion Pursuit Analyzer (PLPA) which was reported already (Jap. J. Physical Fitness & Sport. Med. 1970,20 : 14-23.), however, can record three-dimensional locomotion and electromyogram of exercise at once on the same graphic paper. Therefore, more accurate analysis can be afforded by above mentioned apparatus. Three-dimensional locomotion of lumbar region is considered as an important for coaching skills in exercise, that is very fast and complicated. In the Present report was proceeded to analysis three-dimensional locomotion of lumbar region in batting, racket swing, baseball throw, javelin throw and shot put, and to investigated the difference among there three-dimensional locomotion of lumbar region. The obtained results are as follows : 1) In ball throw, lumbar moved forward to lower left at first and immediately before when ball was release it moved backward to upper right. 2) In javelin throw, lumbar moved forward to upper left and forward to lower left. 3) In shot put, it moved backward to lower left, and forward to upper left ball was released. From these results, physical exercise in throwing and hitting seemed to be equal fundermentally, but three-dimensional locomotion obtained by PLPA were considerably differented, especially in throwing.
