Glycogen is a readily mobilized storage form of glucose. It is a very large, branched polymer of glucose residues that can be broken down to yield glucose molecules when energy is needed.

“Because recovery modalities typically target blood flow, they may theoretically alter glucose availability to muscle during recovery and therefore alter the process of glycogen synthesis. If muscle blood flow is altered by PCD (pneumatic compression device), then extraction of glucose from the blood may be changed, in which case, glycogen replenishment, and blood glucose and insulin may be affected.”
