Nutrition Strategies for Recovery After Exercise
Recovery nutrition refers to the intake of food and fluids after exercise to help the body restore energy stores, repair tissues, and prepare for future performance. In IB Sports, Exercise and Health Science (SEHS), recovery nutrition explains how athletes adapt to training and reduce the risk of fatigue and injury.
Effective recovery allows athletes to train consistently and maintain performance across multiple sessions. Poor recovery nutrition can lead to prolonged fatigue, reduced adaptation, and increased injury risk.
Goals of Post-Exercise Nutrition
The main objectives of recovery nutrition are to:
- Replenish depleted glycogen stores
- Repair damaged muscle tissue
- Restore fluid and electrolyte balance
- Support long-term training adaptations
In IB SEHS, students should understand that recovery nutrition is essential for both short-term performance and long-term improvement.
Carbohydrates and Glycogen Replenishment
After exercise, muscle glycogen levels are often reduced, especially following endurance or high-intensity activity. Consuming carbohydrates after exercise helps restore these stores.
Key points include:
- Glycogen replenishment is fastest soon after exercise
- Adequate carbohydrate intake prepares muscles for the next session
- Low carbohydrate intake delays recovery
In IB exam answers, linking carbohydrates to glycogen restoration and fatigue prevention is essential.
Protein and Muscle Repair
Protein plays a critical role in repairing muscle tissue damaged during exercise. Resistance training and high-intensity exercise cause microscopic muscle damage that must be repaired for adaptation to occur.
Protein intake after exercise:
- Supports muscle repair
