Hepatic glycogen stores deplete rapidly, replete slowly.  Liver glycogen is
essentially zero upon waking, and is depleted quite rapidly during exercise.
 Muscle glycogen stores are more stable.  After a 24 hour fast, muscle
glycogen is almost unchanged, liver glycogen very low.  Muscle and liver
glycogen are quite different, and maximal storage of CHO in muscle is easily
achieved compared to liver. Liver glycogen is poorly refilled by glucose
alone vs gluconeogenic precursors + glucose.  G. Brooks, McGarry and others
have done nice work regarding this area.  Tim Noakes also.
