This study looked at the rate
of muscle glycogen synthesis during 2 and 4 hours of recovery after depletion by exercise using two energy equivalent carbohydrate drinks.
Nuclear magnetic resonance studies in vivo show that
defective muscle glycogen synthesis is a major cause for insulin resistance and propose that the rate - limiting step is glucose transport (rev. in 25).
Carbohydrate - rich foods with a moderate to high glycemic index provide a readily available source of carbohydrate
for muscle glycogen synthesis, and should be the major carbohydrate choices in recovery meals.
Symptoms of insulin resistance include decreased stimulation of
muscle glycogen synthesis as well as defects in glycogen synthase activity and glucose uptake (18).

muscle glycogen synthesis after exercise training in insulin - resistance subjects.
The third paper, «Effect of different post-exercise sugar diets on the rate of
muscle glycogen synthesis» [3], isn't available to me electronically, so we'll have to work from the abstract.
Muscle glycogen synthesis rates were:
