Exercise increases the generation of oxygen free radical an lipid peroxidation. Polyphenol and vitamin C, E are known to prevent lipid peroxidation during exercise. Among the known polyphenol, the polyphenol extracted from Green tea as used has the similar effect of antioxidant. Therefore we examined the effects of acute polyphenol or vitamin complex(vitamin C+E) on antioxidants enzymes activities in rat(N=40). All rats were exercise training on the treadmill for 6weeks (25m/sec for 1hour). They were administered 5% of polyphenol and 50㎎ of vitamin C+E before the exercise at the final day of the experiment in acute administration group(APA; acute polyphenol administration, AVA; acute vitamin complex administration, AVPA; acut vitmin complex & polyphenol administration) and theother group was administered the same amount of water at the same time point(CON). One-way ANOVA was performed as the statistical analysis. MDA concentrations in liver was significantly decreased in APA or AVPA. But gastrocnemius red, white muscle were not statistically significant. In addition, polyphenol administration has the positive effect compared with vitamin complex administration. SOD concentrations in liver were significantly increased in APA or APVA. However, skeletal muscle SOD concentrations were not statistically significant. These results suggested that acute polyphenol administration reduced the risk of lipid peroxidation during exercise in rats. Moreover, acute administration of polypheonl and vitamin complex & polyphonol increased the antioxidative activity that prevent the lipid peroxidation during exercise in rats.
