The purpose of this study was to determine the effects of vitamin C, E ingestion on lipid peroxidation following exhaustive exercise. Five male subjects performed incremental maximal treadmill running. No significant difference was observed in exhaustion time and Vo₂max among placebo, vitamin C and E ingestion.
　There were no significant differences in blood ammonia, lactate, free fatty acid and uric acid concentrations among placebo, vitamin C and E ingestion following the maximal exercise. Serum lipid peroxides increased significantly (P< 0.05) as compared with the resting level following the maximal exercise with the placebo. However, no significant changes were found in vitamin C and E ingestion following the maximal exercise. Furthermore, serum lipid peroxides in vitamin E ingestion were significantly (P< 0.05) lower than with the placebo and vitamin C ingestion at rest and following the maximal exercise.
　These results suggested that, 1 ) vitamin C and E ingestion did not affect energy metabolism and uric acid production, however 2 ) vitamin C and E ingestion decreased lipid peroxidation following exhaustive maximal exercise.
