Nutrient timing refers to the strategic planning of nutrient intake around training sessions and competitions to enhance recovery, performance, and muscle growth. For athletes, consuming a mix of carbohydrates and proteins before and after workouts can significantly improve glycogen replenishment and muscle repair. Pre-exercise meals provide the necessary energy to perform at peak levels, while post-exercise nutrition aids in recovery. Properly timed nutrients optimize body composition changes and support endurance, strength, and overall athletic performance.
