The ATP-PC system is important for providing quick energy during high intensity, short duration activities. The ATP-PC system is anaerobic which means that is does not require oxygen. This is important in sports where sudden and powerful movements are required, such as shot put or sprinting. As the muscle can use ATP to produce energy and movement without having to wait for oxygen to be delivered.

this is an anaerobic system so it does not use oxygen. here ATP is made by the partial breakdown of glucose and glycogen. it involves anaerobic glycolysis (the breakdown of glucose or glycogen to produce ATP). Lactic acid is produced, causing stiffness and fatigue. this is used in sports such as 400m race and 200m swim.

this is a long term energy system so its meant to last. this uses oxygen to last a long time. this is a breakdown of fatty acids to provide a large amount of ATP. Carbon dioxide and water are by products. this occurs in the mitochondria of cells-powered stations responsible for converting food into energy. this is a slow system by is continuous. used un long distance running such as marathon or a triathlon.

The energy continuum describes how the different energy systems interact to provide energy for the human body during exercise. There are three energy systems within the energy continuum :ATP/PCR Lactic acid Aerobic system As exercise begins the PCR/ATP energy system provides the most energy for the human body, once exercise reaches around 10 seconds the lactic acid takes over and starts to provide the majority of energy. Lastly, the aerobic system will take over after around 3 minutes of exercise.
