ABSTRACT

Lee, M.G., Choi, H.H. Effects of type of contraction and order of exercise loading during isokinetic exercise on delayed onset of muscle soreness. Exercise Science, 12(3): 517-528, 2003. Isokinetic exercise has been limited to utilize in the field due to the delayed onset of muscular soreness(DOMS) although it has many advantages such as lowering burden to cardiovascular system, enhancing muscular strength effectively, and lowering muscular fatigue after exercise. This study was designed to examine the effects of type of contraction and order of exercise loading during isokinetic exercise on concentration of creatine kinase(CPK), known to be an index of DOMS. Ten male collegiate students, aged 23.8±2.7 yrs, were volunteered to participate in this study as subjects. All subjects performed four bouts of isokinetic exercises, i.e., concentric and eccentric exercises which were ordered low to high and high to low intensity, respectively. Concentration of CPK was measured at rest and every 12 hour during 60 hours of recovery phase after each exercise. Eccentric exercise, which was performed at same intensity as concentric exericse in terms of maximal force, induced significantly lower concentration of CPK than concentric exercise in both loading order trials throughout the recovery phase. It was concluded that eccentric isokinetic exercise could reduce DOMS more compared to concentric isokinetic exercise.
