Nutrition supports athletic performance during competition by providing the necessary energy and nutrients crucial for optimal functionality. Consuming a balanced diet rich in carbohydrates, proteins, and healthy fats ensures athletes have adequate fuel for their activities. Carbohydrates are particularly vital for sustaining energy levels during high-intensity performance. Additionally, hydration is key to maintaining performance and preventing fatigue. Nutritional strategies such as meal timing and supplementation can further enhance endurance, recovery, and overall athletic success.
