Energy Systems
Energy Systems
Our body needs a supply of energy to complete day to day tasks and to simply be able to move. We have more than one energy system, we have 3 in total and these are * ATP (anaerobic) * Lactic acid (anaerobic) * Aerobic (aerobic)
All three off these energy systems are fuelled by the same chemical called ADP-PC. These systems produce this chemical at different speeds, for example the ATP system produces the chemical very fast as for the aerobic energy system produces it very slowly. ATP is made up from Adenine and 3 phosphate groups it starts up as ADP (adenosine diphosphate) and by adding the chemical Phosphocreatine it becomes ATP.
Our body can function with or without oxygen. Movements that are short and explosive, classed as anaerobic energy production are powered by energy systems which do not need oxygen whereas repetitive movements which require oxygen need an energy system which requires oxygen to function such as the aerobic energy system. Energy is vital to produce muscle contractions. And energy is produced from foods consumed but mainly carbohydrates and fats. * Carbohydrates – carbohydrates are broken down by the body into glucose, a simple sugar. If the body does not require it immediately it is stored in the liver and muscles. * Fats – broken into fatty acids When our body burns these substances it produces ATP and once the chemical bond in the ATP is broken it produces energy for muscular contractions. Only ATP can provide the energy for muscular contractions. But it can be produced by all three of the energy systems.
ATP System
ATP makes produces energy in the muscles and then muscular contractions are made using the ATP then the ATP becomes ADP, our body adds CP to the ADP and it then becomes ATP again and the cycle begins again.
This is the first energy system to kick into action but the quickest to fatigue, this system only last for about 10 seconds of high intensity exercise. ATP is produced
