  1. 1. Energy Systems ATP-PC energy Lactic acid Aerobic energy system energy system systemAlternative Alactic system, Anaerobic glycolysis, Oxygen system, aerobicname phosphocreatine or lactacid system glycolysis creatine phosphate system, phosphagen systemFuel source Phosphocreatine (PC or Glycogen At rest: FFAs PCr) or creatine During exercise: phosphate (CP). CHO Interchangeable names Fats (when glycogen for the same chemical sparing and when glycogen stores diminished) Protein (last resort)Intensity of Very High (>95% max HR) High (>85% max HR) Restingactivity Used for increase in Sub max intensity (<80% intensity in long duration max HR) eventsDuration 1-5 seconds 5-60 seconds >75 secondssystem isdominantduring activityPeak Power 2-4 seconds 5-15 seconds 60-90 secondsAmount of 0.7 ATP for each PC 2-3 ATP for each glucose CHO (38 ATP per glucoseATP produced molecule molecule molecule) Fats (441 ATP per triglyceride molecule)Speed of Instantaneous Fast Mediumproduction Simple chemical Longer chemical Complex chemical reactions reactions reactions Availability of oxygen delays max powerBy products Inorganic phosphate (Pi) Lactic acid C02 ADP Hydrogen (H+) ions H20 ADP HeatTotal duration 0-10 seconds 10-75 seconds >75 secondsduring activity
