Articles : The Effect of Diet Control and Swimming Exercise on Reactive Oxygen and Antioxidant Enzymes Activity in Cholesterol Diet Rats
Abstract
The Purpose of the Present investigation was to evaluate the effects of diet control and swimming exercise term on reactive oxygen and antioxidant enzymes activity of cholesterol diet rats. Twenty-four male SD rats (6 weeks old) were randomly divided into control group (CG), diet treatment group (DT), swimming exercise group (SE) and diet + swimming exercise group (DS), and then swimming exercise group and diet + swimming exercise group swam unloaded for 6 weeks (6 days/week, 30 min/day) with diet control treatment. Analytical items were reactive oxygens(xanthine oxidase and MDA) and antioxidant enzymes(glutathione and glutathione reductase) activity. All data were expressed as mean and standard deviation by using SPSS/PC + program, and to evaluate the differences between groups, data were analyzed by one-way analysis of variance and Duncan multiple range test (?=.05) was performed to test the significant levels of differences between groups. The conclusions obtained from this study were as follows; 1. In xanthine oxidase, all 3 groups (DT, SE and DS) were significantly lower than control group (P<.001), and swimming exercise group were significantly lower than diet treatment group and diet+swimming exercise group (P<.001). In malondialdehyde (MDA), all 3 groups were significantly lower than control group (P<.001), and swimming exercise group and diet+swimming exercise group were significantly lower than diet treatment group and diet + swimming exercise group (P<.001). 2. In glutathione, swimming exercise group and diet + swimming exercise group were significantly lower than control group and diet treatment group (P<.001). In glutathione reductase, all 3 groups (DT, SE and DS) were significantly higher than control group (P<.001), and swimming exercise group were significantly higher than diet treatment group and diet + swimming exercise group (P<.001).
Key Words: swimming exercise, reactive oxygen, antioxidant enzyme, cholesterol diet
