운동량이 젊은 성인 남자의 비타민 C와 E 섭취량 및 혈장 비타민 C, $\alpha$-tocopherol 및 $\gamma$-tocopherol 수준에 미치는 영향

The Effects of Exercise on the Vitamin C and E Intakes and Their Plasma Levels of Vitamin C, $\alpha$-tocopherol and $\gamma$-tocopherol in Young Male Adults

We investigated the effect of physical exercise on the intakes and plasma levels of vitamin C and E in young male adults. The study population were divided into two groups: small-amount exercisers($\leq$ 30min/day, n=29) and moderate-amount exercisers(> 30min/day, n=32) according to their physical exercise habits measured by a questionnaire. Dietary intakes of vitamin C and E of the subjects were estimated by the 24 hour recall method. Plasma lipid profiles, vitamin C, $\alpha$-tocopherol and ${\gamma}$-tocopherol levels were analyzed. No significant differences were observed in total cholesterol, TG, HDL-C and LDL-C of plasma between two groups. Plasma vitamin C and $\alpha$-tocopherol levels in moderate-amount exercisers were significantly higher than those in small-amount exercisers, although dietary intakes of vitamin C and vitamin E were not significantly different between two groups. However, plasma ${\gamma}$-tocopherol level of moderate-amount exercisers did not significantly differ from small-amount exercisers. There was a positive correlation between the amount of exercise and plasma $\alpha$-tocopherol level. These results suggest that moderate amount of exercise over 30 min per day would lead to a healthy life with an activated antioxidant defence system against oxidative stress.(Korean J Nutrition 34(3) : 306~312, 2001)
