The purpose of this study was effects of exercise intensity difference on MDA and SOD concentration in blood in elementary obese children. In this study, 40 elementary obese children were chosen, there were divided into 80% high-intensity exercise group(N=20) and 55% moderate-intensity exercise group(N=20). Blood-collecting was carried out four times(Rest, After exercise, 1 hour, 24 hour), and with the collected blood, plasma malondialdehyde(MDA), superoxide dismutase(SOD) were analyzed. It was shown that MDA & SOD in blood value at all exercise groups increased significantly after exercise rather than rest. After 24 hour, all exercise groups returned rest level in MDA & SOD. But high-intensity exercise group increased rather than moderate-intensity exercise group in MDA & SOD. To synthesis this result, Exercise increased considerably MDA & SOD concentration in blood in elementary obese children, Moderate-intensity exercise has effective in antioxidant system in body.
