N2  - In this study, the effect of vitamin E on endurance capacity was investigated by analysis of plasma lactate (PLa) concentrations and on oxidation mechanisms was evaluated by serum sulphydril groups (RSH) and lipid peroxidation products (TBARS) in a treadmill running exercise, performed at the intensity of 4 mM lactate threshold. In 8 voluntary subelit male athletes, PLa, serum vitamin E, serum RSH and serum TBARS concentrations were analyzed; 1) before taking any kind of substance, 2) after taking placebo for one week, 3) after taking 1000 UI/day vitamin E for one week. It was observed that, 1000 UI/day vitamin E supplementation for one week is increased serum vitamin E concentration as %75.9. There was no effect of placebo on any parameter. Before vitamin E supplementation, exercise was increase serum TBARS level significantly (p<0.05). However, after vitamin E supplementation, significant reduction on this increment ratio (p<0.05) was determined. Vitamin E supplementation had no significant effect on serum RSH levels. Although, PLa concentration, received after 20 min treadmill exercise was decreased from 4.7±07 mM to 4.3±1.5 mM and there was a negative correlation between serum vitamin E and PLa concentrations after vitamin E supplementation, these differences and relationships were not statistically significant.
