Exercise, free radical generation and vitamins.
Physical activity raises oxygen demand by many fold, causing a parallel increase in the formation of oxygen radical species. Vitamins are concerned with either energy metabolism or free radical scavenging. This review outlines the possible damage to cell structures following strenuous exercise and the role of vitamins as part of natural anti-oxidant defence systems. A brief discussion is included on the relationship between physical activity, the immune system and cancer.
