Background It is reported that high-intensity physical exercise may induce oxidative stress. Therefore, the purpose of this study was to investigate the change of blood oxidative stress markers after a high-intensity exercise in young women Methods Eight sedentary women who have regular menstrual cycles participated in this study. Regular menstrual cycles were determined by basal body temperature (BBT) and urinary ovulation test for 2 mouths prior to this study. All subjects performed the bicycle ergometer exercise (for 22.5 min at 80% VO2max). Lactate was determined from blood of Pre-and Post-exercise (PO). Blood oxidative stress markers (erythrocyte thiobarbituric acid reactive substances: TBARS, Superoxide dismutase: SOD, Glutathione Peroxidase: GPx and serum Creatine PhosphoKinase: CPK) were determined from blood of Pre-and Post-exercise (PO, P2, P12 and P24). Results In this results, lactate was increased clearly at the P0 compared with Pre (p<0.05). And TBARS increased significantly P12 compared with Pre (p<0.05). SOD activity also decreased significantly P24 compared with Pre (p<0.05). However, GPx activity did not show statistically significant changes by the high-intensity exercise. CPK significantly decreased P0 and increased significantly P12 compared with Pre (p<0.05). Conclusions In the menses, high-intensity exercise may increase the blood oxidative stress in the young woman which has a normal menstrual cycle. In particular, the influence of ROS is very high after P12. Therefore, sedentary women had better do not intense exercise in the menses.
