1.0 Introduction
The human body operate on three energy systems: Phosphate Energy System, (ATP/CP or CP SPLITTING), Lactic Acid Energy System (Anaerobic Glycolysis) and Aerobic Energy System (Oxygen System). ATP is when an enzyme splits one of the three phosphate molecules from Adenosine Triphosphate and this releases large amounts of energy that the muscle fibres use to create movement, this turns ATP into Adenosine di-phosphate (ADP), However, only a small amount of ATP is stored within the muscles cells, about 10-15 seconds and takes 2-3 minutes to fully replenish. When ATP is depleted the body turn to anaerobic Glycolysis for energy. This process breaks down glycogen and glucose (Sugar and Fat) to produce energy. This process creates a by-product called ‘pyruvic acid’ which converts into lactic acid if there is insufficient oxygen circulating in the muscles. If Lactic acid accumulates, the process of anaerobic glycolysis slows down, resulting in fatigue. This energy system takes 20-60 minutes depending on the fitness level to remove the accumulated lactic acid after maximal exercise. The third energy system is a much slower process of collecting energy, however; the energy produced lasts longer than the other two energy systems, and therefore it is
