摘要

The purpose of the study was to investigate the effects of supplementation containing antioxidants on oxidative stress and muscle damage in endurance exercise. Fifteen untrained healthy males (mean age 24.4± 2.4yr) were assigned to drink either on antioxidant beverage (A) or water (W) on two sessions separated by I week. The antioxidant beverage contained 0.2 mg vitamin E, 20 mg vitamin C, 0.12 mg n-carotene, 4.0 g fructose, 1.0 g glucose and 1.0 g sucrose per 100 ml. Subjects consumed 500m1 of A or W one hour before exercise and 150 ml every 15 mm during an 80% maximal 02 consumption (VO2max) treadmill exercise. The concentrations of biochemical parameters were measured pre-exercise, ex-30 mm, and exhaustion. The results indicated that no significant differences were observed between the two groups for superoxide dismutase (SOD) activity and glutathion (GSH) concentration. The malondialdehyde+4-hydroxynonenal (MDA+4-HNE) production at exhaustion in A group was significantly lower than W group. There was also no significant difference in creatine kinase (CK) and lactate dehydrogenase (LDH) activity for the two groups during exercise, eventhough the A group tend decreased the activity of CK. In conclusion, ingestion of antioxidant beverage before and during exercise might help to decrease lipid peroxidation.
