Physical Locomotion Pursuit Analyzer (PLPA) wich was reported already (J. Physical Fitness. Japan, 1971,20 : 14-23), this apparatus have been investigated relationship between three dimentional locomotion of lumbar region and its physiological function. In the present experiment was designed to investigated the interrelation of three dimentional locomotion of lumbar region, electromyogram of lower extremities in the walking, running and up-down stair movement. The obtained results are as follow : 1) In walking movement, up-down motion and left-right motion of a point of lumbar region were displaced by supporting legs. 2) In slow running on the load, up-down motion was remarkably increased, but that of left-right motion. 3) In up-stair movement, these displacement of that point of lumbar region was slower than that of down-stair locomotion. However, in down-stair movement, left-right motion of that point of lumbar region was apparently decreased and up-down motion showed transient displacement. 4) In treadmill running, left-right motion of that point of lumbar region gradually increased with corresponding to the increase of running velocity. Up-down motion of that point of lumbar region abruptly increased at the speed of 200m/min, but over the running speed of 250m/min it inversely decreased. 5) These result would indicate necessary of three dimentional analysis on estimation of the walking, running and up-down stair movement.
