Kinetics of Oxidative Stress Markers at Rest and in Response to Aerobic and Acute Exercise in Judokas Men

The purpose of this study was to compare oxidative modifications following aerobic and acute exercise in judokas men. Judokas performed in random order a low-intensity aerobic exercise bout on a cycle ergometer. Blood samples were analyzed for total antioxidant status, malondiladehyde, glutathione peroxidase, superoxide dismutase, glutathione reductase, and -tocopherols. The main results of this study were (a) aerobic and combined exercise had a significant effect on TAS (b) lipid peroxidation indicated by the levels of MDA showed a significant increase after aerobic and combined exercise (c) aerobic and combined exercise induced an increase in GPx, SOD and GR concentrations. Our results suggest different responses within the antioxiant system dependent on the intensity and duration of exercise.
