The purpose of this study was to evaluate the effect of vitamin E supplementation on oxidative stress and inflammatory status in female athletics conducting different types of exercise (anaerobic vs. aerobic). Participants consumed Vitamin E (1,000 mg/day) for 4 weeks and conducted exhaustive running exercise on a treadmill before and after treatment. Collected blood samples were analyzed for malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPX), and C-reactive protein (CRP). SOD and GPX were significantly increased, MDA and CRP were significantly decreased after vitamin E supplemented for 4 weeks. Compared to aerobic athletics group, anaerobic athletics group had significantly higher MDA at immediately after exercise, and significantly lower GPX at rest period. There was a positive correlation between CRP and MDA before vitamin E supplementation; however it disappeared after supplementation in anaerobic athletics group. These results suggested that vitamin E supplementation for 4 weeks significantly reduces oxidative stress by enhancing antioxidant capacity, and this result may improve inflammatory status.

This study was to investigate the effect of vitamin E supplementation on antioxidant enzyme and immune response after exhaustive exercise. Ten female athletes(long-distance swimming) subjects participated in this study. They are divided into two groups: vitamin E supplemented(vitamin E 1,000 mg/day) and placebo, and supplemented for 4 weeks. All subjects exhaustive running exercise on a treadmill at before and after treatment. Blood was sampled from a forearm vein at rest, immediately post-exercise, and 30 min after exercise. These samples were analyzed for antioxidant enzyme and immune cell factors. Superoxide dismutase(SOD), glutathione peroxidase(GPx), leucocytes and neutrophil were significantly increased, lymphocyte was significantly decreased after vitamin E supplemented for 4 weeks. Compared with placebo, vitamin E supplemented had significantly higher SOD, GPx and lymphocyte, and significantly lower leucocytes and neutrophil. These results suggested that vitamin E supplementation for 4 weeks significantly improved antioxidant enzyme SOD and GPx activities. Also it was found that according as immune cell leucocytes, neutrophil and lymphocyte the recovery operation of damaged tissue against inflammation was far fast accelerated. So that it was thought very important factor to take antioxidant to athletes doing chronic high intensity exercise.
