Glycogen synthesis is, unlike its breakdown, endergonic—it requires the input of energy

Glycogen reserves can supply it for a period of time but when glycogen reserves are depleted glucose must be synthesized from fat and protein by a process called gluconeogenesis.

While the exact contribution of each of these factors is unknown, they may act in combination to stimulate rapid muscle glycogen re synthesis rates.

"...re-synthesis after short term, high intensity exercise (15.1 to 33.6 mmol/kg/h) is much higher than glycogen re-synthesis rates following prolonged exercise (approximately 2 mmol/kg/h), even when optimal amounts of oral carbohydrate are supplied (approximately mmol/kg/h)." My take on this article, and the fast food, more liberal repletion concept?

Both glucose and insulin regulate glycogen synthase activity, and higher levels of them improve muscle glycogen synthesis.
