Glycolysis time frame during exercise
WebGlycogen/glucose metabolism ( Fig. 151.1) Anaerobic glycolysis is the main metabolic pathway used in the setting of limited oxygen supply during exercise. It is used during high-intensity, sustained, isometric muscle activity.1 It is inefficient from an energetic standpoint and produces only two ATP molecules per glucose molecule, which is 19 ...
