Dietary antioxidants play a crucial role in enhancing athletic performance by combating oxidative stress induced by intense exercise. Vitamins C and E, along with polyphenols found in fruits and vegetables, help reduce muscle soreness and inflammation, promoting quicker recovery. Improved blood flow and oxygen delivery can also be attributed to these compounds, leading to better performance during training and competitions. However, it's essential to balance antioxidant intake as excessive supplementation may impair adaptations to exercise.
