Journal of Exercise Nutrition & Biochemistry 2004;8(3):281-288.

Abstract

The purpose of this study was to evaluate the effects of regular swimming training and one time swimming exercise on response of antioxidant enzymes activity in rats. 30 male SD rats (6 weeks old) were randomly divided into regular swimming training group and one time swimming group. Also, regular swimming training group was swimmed for 8 weeks (5 days/week, 50 min/day). All data were expressed as mean and standard deviation by using SPSS/PC+ program, and data were analyzed by Paired t-test (α = .05), and Independent t-test was performed to test the significant levels of differences between groups. The results obtained from this study were as follows; 1. Superoxide dismutase(SOD), glutathione peroxidase (GPX), and catalase (CAT) were significantly (p＜.05) increased in regular swimming training group after 8 weeks comparing to the 0 levels. 2. But. superoxide dismutase (SOD), glutathione peroxidase (GPX), and catalase (CAT) were not significantly differentiated in one time swimming group after 8 weeks comparing to the 0 levels. 3. Superoxide dismutase (SOD), glutathione peroxidase (GPX), and catalase (CAT) were significantly (p＜.05) differences between regular swimming training group and one time swimming group after 8 weeks. In summary, given these results were able to confirm the effects of antioxidant enzymes activity on the prolonged aerobic exercise training. However, we suggest that these response of antioxidants enzymes activity will be different from various of exercise training mode, volume, and intensity, respectively.
