Nutrition significantly affects athletic performance by providing the necessary fuel for energy production, muscle repair, and recovery. Proper macronutrient ratios—carbohydrates for energy, proteins for muscle growth, and fats for sustained fuel—are essential for optimized performance. Inadequate nutrition can lead to fatigue, reduced strength, and prolonged recovery times. Hydration also plays a critical role, impacting endurance and cognitive function during physical activities. Athletes who focus on balanced, nutrient-rich diets often see enhanced performance and better overall health outcomes.
