Antioxidants play a significant role in athlete nutrition by combating oxidative stress, which can occur during intense physical activity. High levels of free radicals generated during exercise can damage cells and lead to fatigue and decreased performance. Antioxidants, found in fruits and vegetables, neutralize these free radicals, thereby promoting recovery and reducing muscle soreness. Common sources include vitamins C and E, beta-carotene, and flavonoids. Including antioxidant-rich foods in an athlete’s diet supports overall health, optimizes recovery, and enhances performance by reducing the risk of injury and illness.
