muscle glycogen

Muscle glycogen is the stored form of carbohydrate in your muscles, acting as a readily available energy source during physical activity. When you consume carbohydrates, your body converts some into glycogen and stores it in your muscles and liver. During exercise, glycogen is broken down into glucose to fuel muscle contractions. Adequate glycogen levels are essential for optimal performance and endurance, especially in high-intensity or prolonged activities. Once depleted, fatigue can set in, requiring rest or carbohydrate intake to replenish these energy stores.
