To improve athletic endurance, several nutritional strategies can be employed. First, it's essential to consume a well-balanced diet rich in carbohydrates, which serve as the primary energy source during exercise. Foods like whole grains, fruits, and vegetables provide necessary fuel. Additionally, staying hydrated is critical; fluid loss during exercise can impair performance. Incorporating protein post-exercise aids in muscle recovery. Some athletes may also benefit from using sports supplements like electrolytes or energy gels during prolonged activity. Ultimately, a proper nutritional strategy can enhance endurance and performance.
