They are three primary energy system that supply the body with ATP during exercise. Phosphagen system(anaerobic), Anaerobic glycolysis, and Aerobic glycolysis. To better understand this, we first need to know the different between aerobic and anaerobic. Aerobic means with oxygen and anaerobic mean without oxygen. Phosphagen system is anaerobic, which means doing an exercise without the need of oxygen. Phosphagen system involves the breakdown of creatine phosphate and stores ATP to resynthesize ATP for immediate use. This is a fast twitch muscle fiber because it utilizes primarily the phosphagen system and allows greater force production. Athletes in this system are, powerlifters, strongman, sprinters, football players (kicker, D and O-Line)

It does not require oxygen, but instead involves the breakdown of glucose and glycogen to form ATP. Anaerobic glycolysis produces ATP quite rapidly and is used during activities that requires large burst of energy over a little longer period (11 seconds- two minutes). The anaerobic glycolysis occurs within the cytoplasm and breaks glucose down into a simpler component called pyruvate. Anaerobic glycolysis is also a fast-twitch muscle fiber. Athletes in this system are, bodybuilders, badminton, swimmer, Olympic runners (200m-400m dash) etc. some exercises in the anaerobic glycolysis system are, 15-20 reps’ workouts, negative reps’ workout, swimming etc. The third energy system is Aerobic glycolysis, it’s a slow-twitch muscle fiber that requires oxygen to produce ATP. When enough oxygen is available, more ATP can be produced because the breakdown of carbohydrate and fat. Carbohydrate metabolism requires less oxygen than fat metabolism. As exercise intensity increases, the body uses more glucose than fat for energy. The enzymes used in this system is acid coenzyme A. It occurs in the mitochondria of the cell and used for activities requiring long energy production. Aerobic glycolysis has a slow rate of ATP production and mainly used during longer duration, lower-intensity activities after the anaerobic and phosphagen system have fatigued. Athletes in this system are marathon runner, long distance runner, soccer player
