The process during which muscle glycogen is converted to pyruvic acid is known as aerobic glycolysis. In this metabolic pathway, glycogen is broken down into glucose, which then undergoes glycolysis to produce pyruvic acid. This process requires oxygen and takes place in the presence of sufficient oxygen supply, leading to more energy being produced than in anaerobic glycolysis. The end product, pyruvic acid, can then enter the citric acid cycle if oxygen is available.
