Background : Intense physical exercise may promote production of free radicals in the body that may cause various types of oxidative damage. The purpose of this study is to investigate the effect of acute exercise on blood oxidative stress markers in female athletes with the different menstrual cycle status.
Methods :Subjects were divided into two groups(eumenorrheic athletes; EA, irregular menstrual athletes; IMA), and they performed acute exercise by bicycle ergometer. Estradiol, TBARS, T-SOD activity, CPK, Glutathione redox status indices (TGSH, GSSG, GSH, GSSG-TGSH ratio) were determined from blood sample of the pre-and post-exercise.
Results :TBARS of two groups showed no statistically significant changes by acute exercise. T-SOD activity decreased significantly in the IMA group but it tended to decrease during post-exercise period in the EA group. CPK of two groups showed no statistically significant changes by acute exercise. In the glutathione redox status, GSSG increased significantly in the IMA group but it tended to increase during post-exercise period in the EA group. GSSG/TGSH ratio decreased significantly in the IMA group but it tended to decrease by acute exercise in the EA group.
Conclusions : Acute exercise may influence on blood oxidative stress markers in the female athletes with the different menstrual cycle status, especially, it seems that the oxidative stress is larger in the IMA group. In the future, therefore, the study about the oxidative stress prevention in the female athletes who have irregular menstruation will be needed. (Korean J Health Promot Dis Prev 2007 ; 7(3):180~186)
