Isi artikel

Exercise appears to increase reactive oxygen species that can result in cell damage. Exercise results in increased amounts of m.alondialdehyde in the blood and pentane in the breadth, both serve as indirect indicators of lipid peroxidation. Some studies have reported that supplementation with vitamins C, E, other antioxidants, or antioxidant mixtures can reduce symptoms or indicators of oxidative stress as a result of exercise. However, these supplements appear to have no beneficial effects on performance. Exercise training seems to reduce the oxidative stress of exercise, such that trained athletes show less evidence of lipid peroxidation for a given bout of exercise and an enhanced defense system in relation to untrained subjects. Whether the body natural antioxidant defense system is sufficient to counteract the increase in reactive oxygen species with exercise or whether additional exogenous supplements show evidence of reduced oxidative stress: evidence tend to support the latter.
