The purpose of this study was to investigate the effects of vitamin C supplementation and yoga practice
on total antioxidant status (TEAC), lipid peroxidation, and blood lipid profiles of middle-aged women. Thirty two women (53.34±5.08 years old) in B city volunteered and the signed consents were received before the study. Experimental groups were normal (n=8), vitamin C intake group (n=8), yoga group (n=8), and vitamin C intake with yoga group (n=8). Total experimental period was 12 weeks. Yoga group practiced yoga 3 times a week for 12 weeks with intensity of RPE 13～15. Each practice was 60 minutes. Vt. C group was instructed to take 1 g of Vt. C every day after dinner meal. Changes in TEAC after 12 weeks were 28.23% for the normal group, 30% for Vt. C group, 26.58% for yoga group, and 43.66% for Vt. C with yoga group; the increases in TEAC among groups were not significantly different. Serum malondialehyde (MDA) concentration of the normal group increased by 10% during 12 weeks of experiment while that for the Vt. C, yoga, and Vt. C with yoga group were significantly decreased by 25%, 32.14%, and 33.87%, respectively (p<0.05) compared with the normal group. Neither yoga, Vt. C supplementation nor combined program for 12 weeks were effective enough to change the serum lipid profiles compared with the normal group. In conclusion, Vitamin C supplementation or regular yoga practice seems to have health promoting effects of retarding the oxidative stress by decreasing lipid peroxidation in middle-aged woman.
