Carbohydrates play vital roles in pre- and post-workout nutrition. Before exercise, they provide the necessary energy to fuel activity and enhance performance. Simple carbohydrates, like fruits or energy gels, can quickly supply glucose stores. Post-workout, carbohydrates are crucial for replenishing glycogen stores and supporting muscle recovery. Pairing carbs with protein post-exercise aids in muscle repair and stimulates muscle protein synthesis, which is essential for recovery. An appropriate carbohydrate intake around workouts helps maximize endurance and performance outcomes.
