| Research Abstract |
This study investigated the relationships between the degree of muscle fatigue and changes in the delayed onset muscle soreness(DOMS), biochemical markers of muscle damage and joint performance, induced by calf-raise exercises at two different frequencies. The results suggest that 1) muscle fatigue is less by the faster exercise, 2) the degree of DOMS and the amount of muscle damage markers are related with the degree of muscle fatigue and muscle-specific, but joint performance rapidly recovers after fatigue regardless of soreness or retained biochemical changes, and that 3) fascicle and tendon behavior during exercise is altered in relation to the observed changes.
