Six men were studied during 40 min of cycling exercise to examine the relationship between leg glucose uptake and muscle glycogen concentration. Exercise resulted in significant increases in leg glucose uptake, while muscle glycogen and arterial blood glucose concentrations declined. Arterial plasma insulin levels did not change significantly. There was a significant inverse relationship between muscle glycogen concentration and glucose uptake during exercise which suggests a possible regulatory influence of muscle glycogen on glucose uptake in the early stages of exercise in humans.
