Abstract

Based on the isokinetic contraction of aconcept of resistive exercise, on seven male adults, resistant diffusion was measured by electromyography as a way of studing physical fitness in relation to the half range and full range of motions, biomechnically loaded on the upper and the lower extrimities. The results obtained were as follows: 1. The size of the spike discharge in the half-range and the full-range of motions of both upper and lower extremities was bigger in the case of the flexor group than in the extensor group. 2. The process of the soike discharge of upper extremities was simultaneous in the half-range and the full-range motions alike, whereas the discharge process of lower extremities was consecutive. 3. The spike pattern of both-upper and lower extremities was one-peaked in the case of the half-range motion, but it was two-peaked in the case of the full-range motion.
