fitness training review - glycogen

Approximately 300 to 400 gram of glycogen is stored in the body's total muscle, and about 70 to 100 gram of glycogen is stored in the liver.

Muscle glycogen is a more important energy source than is liver glycogen during moderate-and high intensity exercise; liver glycogen appears to be more important during low intensity exercise.

At relative intensities of exercise above 60 % of maximal oxygen uptake, muscle glycogen becomes an increasingly important energy substrate; and the entire glycogen content of some muscle dells can become depleted during exercise.
