Energy systems and sport
Introduction
All forms of exercise rely on the body’s ability to obtain energy from ingested food, store it until it is released and then utilise it for contraction of muscle. ...
Adenosine Tri Phosphate- ATP
ATP is the immediate energy source available for all biological work. It is one of the most important of the energy rich components and it is stored in most cells, particularly muscle cells. ... When an enzyme called ATPase breaks the bond between the adenosine and one of the phosphate groups, energy is released.
ATPase
ATP ® ATP + Pi + ENERGY
ATP can also be resynthesised by the by-products of its breakdown, Adenosine diphosphate (ADP) and inorganic phosphate (Pi). Adenosine diphosphate is a relatively low energy compound that requires other forms of energy to assist in the resynthesis of ATP.
This series of two or more chemical reactions in which energy provided by the first to initiate the second is called coupled reactions. Our muscles have a limited supply of ATP, which lasts about 2 seconds, there are three systems that the body uses to resynthesise ATP.
