Nutrient timing in sports nutrition is significant as it involves consuming specific nutrients at strategic times to maximize performance and recovery. Pre-workout meals should emphasize carbohydrates for energy, while post-workout nutrition focuses on protein to aid in muscle repair and growth. Timing these meals can enhance glycogen storage, improve endurance, and expedite recovery. Additionally, proper nutrient timing can help prevent fatigue and optimize workout effectiveness. Athletes often benefit from individualized timing strategies to meet their unique energy and recovery needs.
