Proper nutrition enhances athletic performance by providing the necessary macronutrients and micronutrients that fuel the body. A balanced diet rich in carbohydrates is vital for maintaining energy levels during prolonged exercise, while protein supports muscle repair and recovery. Healthy fats contribute to overall energy balance. Additionally, hydration plays a critical role in performance, as even slight dehydration can impair exercise capacity. Nutrient timing, such as consuming specific foods before and after workouts, can enhance energy availability and promote recovery, leading to improved performance outcomes in athletes.
