Document Summary
Food sources, function, health and athlete aspect, no ergogenic affect** Exercise training may increase total antioxidant capacity (exercise increases free radicals, but body adapts and makes own antioxidants) Such adaptations provide protection against free radical damage. Strenuous exercise may generate ros (reactive oxygen species) to overwhelm the body" natural antioxidant defense system. Equivocal research and review findings relative to the effects of antioxidant supplementation. Some studies show reduction in markers of muscle tissue damage. Several studies found opposing effects of supplements (actually need some damage to occur in muscles for adaptations) Some suggest older athletes may benefit (don"t absorb nutrients as well) Multivitamin-mineral supplementation (100-6000% of the rda) has not been shown to enhance vo2max and aerobic capacity, as well as laboratory and field tests of anaerobic and aerobic endurance, such as 400-meter and 15k run performance, in elite athletes. Some athletes may be advise to take a simple one-a-day multivitamin-mineral.
