Glycogen is how our bodies store carbohydrate. It is predominantly stored in our muscles and liver and provides the glucose needed for exercise, particularly the high intensity type. What is glycogen? Glycogen is a branched polymer of glucose used as fuel storage. Plants store glucose in starch, we do it in glycogen (1). Most glycogen in the body is located in the muscle (~300-700g) and liver (~100-200g) (2, 3). Each gram of glycogen is stored in our muscles with 3-5g of water. Therefore, carbohydrate loading will lead to weight gain (3, 4). Roles of glycogen Some of the roles of glycogen include: Fuel source, providing carbohydrate to working muscles (2,…
