In this study the angle of right and left elbow joints and the forces exerted by the upper and under (Lower) Part of the right and left hand were measured in order to observe the difference of Kendo performance between traned and untrained subjects. The results were summarized as follows : 1) In slow and fast swing motion, in the untrained subject, it was observed to flex the right elbow joint on up swing motion. In the trained subject it was observed a tendency to extensible enough the arm. And in the trained subject it was observed a pattern of a flexion and a tendency in the left elbow joint, but m the untrained subject "no stabilized" pattern could be found it wasn't observed established one. 2) In the result observed to force exerted to the hilt of "shinai" in right and left hands, in the right hand it was observed a tenddency to force of "stopping" under on down swing and "draing" on up swing. In left hand it was observed tendency to force exerted upper and under twice at the same time on the other. That is thought the result were "shinai" shaking" when the untrained subject down swing. 3) It was observed large differnce among the trained and untrained subjects at the rate of force right and left handan, in the trained subject it was observed to big force exerted left hand, an in the untrained subject it was observed to it exerted the right hand. That is thought the Trained subject is swing centering around left hand, but the untrained subject is right hand. 4) In comparing the swing speed for both motion, nearly twise of force was required for a fast swing than for the slow swing was abserved.
