ATP-PC energy system

Uses creatine phosphate as a fuel source and provides energy for very high intensity activities lasting 1-5 seconds.

Anaerobic glycolysis energy system

Uses carbohydrates as a fuel source, supporting high intensity activities lasting 5-30 seconds.

Aerobic energy system (submaximal >65% VO2 max)

Utilizes carbohydrates and fats, producing ATP for activities lasting over 30 seconds.

Aerobic energy system (submaximal <65% VO2 max)

Fuel source includes fats, providing energy for extended activities lasting up to 2-3 hours.

Fatigue mechanism of ATP-PC energy system

Fatigue is due to fuel depletion of phosphocreatine (PC).

Fatigue mechanism of anaerobic glycolysis energy system

Fatigue is caused by the accumulation of hydrogen ions (H+).
