P7 – describe the three different energy systems and their use in sport activities
ATP stands for Adenosine triphosphate. It is an important question in sports training because all energy production is powered by this. The training programs that are designed for you or others will target you’re ability to produce energy for power and endurance.
ATP is often referred to as the energy currency of life. The body’s cells use a special form of energy called adenosine triphosphate to power almost all their activities, such as muscle contraction, protein construction, and transportation of substrates, communication with other cells, activating heat control mechanisms, and dismantling damaged and unused structures.
The alactic system is a form of training

Glycolysis is the breakdown of carbohydrates.
The process of lactic acid removal takes approximately one hour, but this can be accelerated by undertaking an appropriate cool down that ensures a rapid and continuous supply of oxygen to the muscles.
The aerobic energy system utilises fats, carbohydrate and sometimes proteins for re-synthesising ATP for energy use.
The aerobic system produces far more ATP than either of the other energy systems but it produces the ATP much more slowly, therefore it cannot fuel intense exercise that demands the fast production of ATP.
While the aerobic system doesn’t produce nearly as much power as the other systems, a major feature is its capacity which is virtually limitless, as it just keeps on producing ATP. This is why it is good for long distance events such as a marathon runner like Mo Farah.
The aerobic system consists of three processes each of which produce ATP. These stages involve more complex chemical reactions than the other energy systems which is why ATP production is much slower. These stages are; Aerobic glycolysis (slow glycolysis), Krebs cycle (also known as the citric acid cycle) and the Electron transport
