<strong>Objective. </strong>The objective of the present study was to explore the effect of vitamin C supplementation on lipid peroxidation and lactate levels in sedentary individuals who performed exhaustion exercised.<br>
<strong>Methods. </strong>10 healthy sedentary male athletes participated to study. They were supplemented with 300 mg oral vitamin C (L-ascorbic acid, Ester-C Plus 500 mg, Solgar-USA) and subjected to acute exhaustion exercise by fatigue developed one time a week for 4 weeks. Exhaustion exercises were carried out until exhaustion developed according to Bruce protocol once a week for 4 weeks. Blood samples were collected from the subjects four times, at the beginning and at the end of the supplementation and before and after exercise, over the 4-weeks study period. The samples were used to analyze MDA, GSH, GSH-Px, CAT, SOD and NO levels by using ELISA colorimetric method and plasma lactate levels by an autoanalyzer device.<br>
<strong>Results. </strong>Exhaustion MDA, GSH, GSH-Px, CAT, SOD and NO levels measured both before and after supplementation were higher than resting levels (p<0.05). MDA, NO and lactate levels that were elevated in exhaustion before supplementation decreased significantly after vitamin C supplementation (p<0.05).<br>
<strong>Conclusion. </strong>The results of our study indicate that the increase in free radical production and lactate levels due to by 4-week exhaustion exercise were offset by vitamin C supplementation. It can be argued in conclusion that supplementation of physiologic doses of vitamin C may be useful for athlete health and performance.</span></span></div>
