Antioxidant supplementation and subsequent oxidative stress of horses during an 80-km endurance race
Brief content of the article
This field study tested the development of oxidative stress and the effects of antioxidant supplementation in an 80-km ride. A precompetition survey revealed that no competitor would participate without vitamin E supplementation; therefore, 46 horses were paired for past performances and randomly assigned to two groups of 23 each for 3 wk of supplementation before the ride. One group (E) was orally supplemented with 5,000 IU of vitamin E per day; the other group (E+C) received that dose of vitamin E plus 7 g/d of vitamin C. The addition of vitamin C had no effect on the variables measured other than the increased ascorbate status.
