Final answer:

Glycogen re-synthesis starts immediately after exercise to replenish the muscle glycogen stores depleted during activity.

Step-by-step explanation:

Glycogen re-synthesis can begin immediately after exercise. This physiological process can be understood through the lens of two metabolic states: the postabsorptive state, where the body relies on stored glycogen for energy, and the postprandial state (after a meal), where insulin facilitates the conversion of excess glucose into glycogen. Directly after exercise, due to an increased demand for glucose, the body has a unique metabolic environment that is particularly conducive to glycogen replenishment.

During exercise, muscle glycogen stores are consumed and must be replenished post-exercise to restore muscle functionality and ensure readiness for future activity. The synthesis of glycogen (glycogenesis) is an important recovery process that begins as soon as the exercise is completed – the body takes advantage of elevated insulin sensitivity and enzyme activity post-exercise to efficiently convert glucose into glycogen in muscle and liver cells.
