The glucose reserve stored in the liver and muscles.
Glycogen is the form of glucose storage in the human body. It is synthesized and stored mainly in the liver (100-120g) and muscles (300-400g).
Hepatic glycogen maintains blood sugar levels between meals. Muscular glycogen provides rapid energy during exercise. Stores are limited (about 2000 kcal total) and are depleted after 90 minutes of intense effort. Insulin stimulates glycogenesis, glucagon, and adrenaline stimulate glycogenolysis.
To maintain blood sugar levels between meals and provide rapid energy to muscles during exercise.
Replenish muscle glycogen with carbohydrates within 30 minutes after intense exercise.
Glycogen is the body's energy battery — it recharges with every carbohydrate meal.
