was to determine the effect of Vitamin C supplementation on oxidative
stress following 30 min moderate intensity exercise. Forty-nine healthy
young women randomly assigned into 500 mg day-1 vitamin C supplement
(n = 25) or placebo (n = 24) groups for two weeks. Before supplementation
and on the day after the intervention period, fasting blood samples were
taken. Then all participants ran (1.4-1.7 m sec-1) for 30 min.
Third blood samples were taken at the end of exercise. Plasma malondialdehyde
(MDA) and vitamin C were measured using HPLC method. Plasma total glutathione
was measured with ELISA method. No significant differences were observed
in demographic and vitamin C intakes before intervention between groups.
Plasma MDA levels decreased and plasma total glutathione increased significantly
(p<0.05) in both groups. No significant differences were observed between
groups after exercise. There were significant differences in plasma vitamin
C concentrations after intervention and exercise between groups. In conclusion,
vitamin C supplementation (500 mg day-1) for two weeks does
not affect oxidative stress markers following moderate intensity exercise
in healthy young women.]]>Alessio, H.M., A.H. Goldfarb and G. Cao,1997719Bloomer, R.J., A.H. Goldfarb, L. Wideman, M.J. McKenzie and L.A. Consitt,200519276285Duthie, G.G., J.D. Robertson, R.J.
