Factors Affecting Performance
What is ATP >>> Adenosine Triphosphate - chemical compound that is the source of energy for muscles
to work.
What are the three main energy systems in the body >>> ATP-PC System, Aerobic System, Lactic Acid
System
What is the ATP/PC System used for? >>> High intensity performance of maximum effort.
ATP-PC System Fuel? >>> Creatine Phosphate
Duration ATP-PC System? >>> 1-10 seconds energy
Activities of the ATP-PC System >>> 100m sprint, shot put, weight lifting, high jump, golf swing, discus
throw
What causes fatigue in the ATP/PC System? >>> when there is no time to break down glycogen and
produce ATP and PC is depleted
What by-products come from the ATP/PC System? >>> Nil
Recovery of ATP/PC System >>> 2-3 minutes and repeated effort is possible.
What is the lactic acid system used for? >>> Intense activity lasting up to 3 minutes
Fuel source of the lactic acid system? >>> Glycogen from stored glucose.
What is anaerobic glycolosis? >>> partial breakdown of glucose to form lactic acid in the absence of
oxygen.
Duration of the lactic acid system? >>> 10-30 seconds of maximal energy and up to 3 minutes near
maximal energy use.
Activities of lactic acid system? >>> 800m run, 200m swim
Fatigue of lactic acid system caused by? >>> Accumulation of lactic acid in muscles as a by product of
energy production in the absence of oxygen
Recovery of lactic acid? >>> Takes up to 90 minutes.
What is the fuel source of the aerobic system? >>> Carbohydrates, fats then proteins in that order.
How long can ATP production occur for in the Aerobic System? >>> Unlimited time.
