Abstract

Based on the isokinetic contraction of a concept of resistive exercise, on six healthy male adults, hemodynamic levels were measured by plethysmography and electrocardiography as a way of studing physical fitness in relation to the half range and full range of motions, biomechanically loaded on the upper and the lower extremities. The results obtained were as follows: 1. After the exercise of the upper extremities, the blood flow at the finger-tip decreased regardless of the half-range or the full-range of motions. As for the blood flow at the radialis artery, it decreased after the half-range of motion, but it increased after the fullrange of motion. 2. After the exercise of the lower extremities, the blood flow at the toe increased regardless of the half-range or the full-range motions. As for the blood flow at the dorsalis pedis artery, it decreased after the half-range of motion, but it increased after the full-range of motion. 3. As for the cardio-motility during the exercise of both the upper and the lower extremities, it was more vigorous at the full-range of motion than at the half-range of motion.
