The brain directly affects the immune system by way of the release of neuropeptides, and through the release of cortisol. It also works through nerve and brain to increase neurotrophin levels affecting recovery and adaptations within the central and peripheral nervous systems. Massage that causes pain is likely to increase cortisol levels. Following the application of a training stimulus, there are minimal amounts of time necessary to allow for restoration of muscle glycogen. You can store glycogen as fast as you deliver it to muscle through your blood stream, coming from your digestive tract.
Presentation is more important than synthesis.
Thus the main limitation on muscle glycogen repletion following a workout or race is the amount ingested, and the rate of blood flow from the small intestine to muscle. Glycogen can be synthesized at a rate of 1 gram per kilogram of active muscle per hour. Given an active muscle mass of about 10kg. Carbo intake immediately following a training session increases glycogen synthesis rate 2 to 4 times. This results from an increased glucose supply to an already high rate of blood flow and high activity of Glut 4.
