High-intensity exercise results in a large breakdown of glycogen. The glycogen lost may reappear as hexose phosphates, lactate, or it may be fully oxidized. Part of the lactate produced may be transferred from muscle to blood. There is, however, incomplete information on the relative importance of each endpoint of glycogen breakdown during high intensity exercise. Therefore, 16 healthy men cycled for between 30 s and 3 min until exhaustion. Muscle biopsies were taken from m. vastus lateralis… CONTINUE READING
