Document Summary

Over the first 30 mins - 1 hour there is not much difference in peoples abilities to performs (despite the fact that one group is ingesting cho regularly and other group isn"t) People will be able to sustain or level up power output when ingesting cho (cho conserves muscle glycogen because they have available glucose coming from blood) Later portion of that particular activity session is where you"re going to see the greatest differences between the 2 groups. If you take cho every 15 mins throughout exercise stamina is going to be improved. Within first 15 mins you see dramatic drop in blood glucose levels. Glucose in blood is going to be used as substrate for glycolysis. There is no stimulus to break down glycogen to glucose from the liver. Finally when we see the drop there is a stimulus, but blood glucose levels are now very low so it takes the liver more time to replenish these glucose levels.
