비타민 E 복용이 운동유형별 여자선수의 산화스트레스 및 염증반응에 미치는 영향

초록

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.
