The aim of the present study was to investigate whether 2 weeks vitamin C supplementation affects recovery from an unaccustomed bout exercise. Sixteen male subjects were allocated either a placebo (P; n = 8) or group (VC; 8). VC consumed 200 mg ascorbic acid twice day, whereas P identical capsules containing lactose. Subjects performed prolonged (90-min) intermittent shuttle-running test 14 days after began. Post-exercise serum creatine kinase activities and myoglobin concentrations unaffected by supplementation. However, had modest beneficial effects on muscle soreness, function, plasma malondialdehyde. Furthermore, although interleukin-6 increased immediately exercise in both groups, values lower than hours (p < .05). These results suggest that has some
