The primary function of antioxidants in the context of exercise is to combat oxidative stress caused by intense physical activity. Exercise increases the production of free radicals, which can damage cells. Antioxidants, such as vitamins C and E, help neutralize these harmful compounds, protecting the body from cellular damage. Adequate antioxidant intake post-exercise can promote quicker recovery, enhance muscle repair, and reduce inflammation, thereby improving performance and overall health in individuals engaging in regular physical activity.
