Abstract

Background: Antioxidants supplementation may provide protection against negative health consequences of oxygen free radicals caused by aerobic and re"sustained exercise. Objective: is to find out the efficacy of anti" oxidant rich nutri bar supplementation on the anti"oxidant status of athletes. Methods: This study is a single" blind randomized prospective intervention design with control group. Sample size calculation suggested statistical power of 0.80, with significance (p<0.001) which gave rise to 20 athletes. The Experimental group (n=20) was supplemented with the formulated nutri bars emphasizing on carotene, vitamins A, C, E daily for a period of 3 months(two bars/day wt=50gms/bar) and control group with a placebo. Bio"chemical parameters namely Glutathione, glutathione peroxidase, superoxide dismutase, Vitamin C and serum Lipid peroxides were assessed at baseline and after 90 days. Subjects belonging to the experimental and control group were requested to preserve a three"day food documentation so as to determine the modifications in the nutrient intake. Statistical analysis was performed using SPSS (version 15). Results: The mean age was 18 ±3.2 yrs. 60 % of the selected athletes were males and 40% females. The athletes of the experimental group showed a significant increase in serum levels of Superoxide dismutase (p=0.000), Lipid peroxides (p=0.005) and gluathione (p=0.000) than control group. The mean levels of vitamin C and glutathione peroxidase decreased in the experimental group (NS) but the same was significant in the control group (p=0.000, p=0.02, p=0.000). Conclusion: Antioxidant effects of the formulated food were useful in improving the endurance of athletes. Supplementation of antioxidant rich nutri bars has beneficial effects on reducing the oxidative stress of the athletes.
