Most combative sports such as boxing, wrestling and Judo terminated to compete within three minutes. On the other hand, the ball games such as basketball, handball and soccer football are performed during more than 15 minutes. In such ball games, the players must develop their maximal efforts during of the intermittent exercise in which the short duration, high intensity exercises are repeated over the mild and moderate exercises, The top runners of the current marathon must spurt over their steady state levels several times during a whole race. This fact seems to be correspondent to the short duration, high intensity exercise exerted during submaximal exercise seen in the intermittent exercise. The submaximal exercise is correspondent to the preparative exercise of players for positioning in the playing field, which was interrupted with the subsequent short duration, high intensity exercises.

Works for assessment of ability on short-term, high intensity exercise has been proceeded. An attempt determines mechanical power output by means of cycle ergometer. However, the previous reports on anaerobic power have not been focused on exercises within five seconds that exerted mechanical power output developes in an accelerating phase in physical activities such as starting of sprint run, cut-in paly in ball games and aggressive action in sport events.
Observation of Human Multi-Joint Arm Movement from the Viewpoint of a Riemannian Distance

This paper aims at analyzing dynamic characteristics of human arm movements from the viewpoint of Rie-manni an distance. In order to evaluate the amount of inertia-induced movement of a multi-joint arm, a measure called inertia-induced measure is developed. By applying the measure to actual human reaching, it is shown that the smooth reaching tends to be closer to the inertia-induced movement than the clumsy reaching. From this observation, it is sug-gested that humans use their own inertia properties efficiently in smooth reaching.
