10. Energy Systems Important note: It is not ever a matter of which system is working, but which system is predominating.

11. Energy Systems ATP-pc System –10-15 seconds –ADP-P -> ADP+Phosphocreatine Anaerobic Glycolytic System –Glycogen -> Glucose -> ATP –1-2 minutes –Lactic Acid “waste” (more about this later) Aerobic System –Glycogen and triglyceride breakdown –Prolonged energy system
