Motion analysis by the photoes which are taken from on direction and various measurement of physiological phenomena at once, have been routine methods for investigation of physiological function and motion of exercise. SN type Physical Locomotion Pursuit Analyzer (PLPA) which was reported already, however, can record three dimensional locomotion and electoromyogram of exercise at once on the same graphic paper. Therefore, more accurate analysis can be afforded by above mentioned apparatus. In the present experiment "balance beam" in which use at first stage motion of waist is comparatively important factors and then muscle group of lower extremities need adjustment function, is selected. As the results electric discharge phenomenon from right and left m. rectus femoris and m. gastrocnemius was clearly observed and furthermore, muscle tension or relaxation to control athelete's posture on balance beam could be recorded in assosiation with of waist during exercise. By improvement of PLPA apparatus relationship between motion and electrophysiological phenmenon of exercise for the other kinds of sports will be investigated.
