Lactic Acid System

-Intense pain most commonly used by athelets felt during exhaustive exercise, espiecally in a long duration sport such as 400m and 800m.

- it happens due to the breakdown of Adenosine Triphosphate (ATP).
-"85 grms of ATP and would use it up very quickly if we did not have ways of resynthesising it"

The lactic acid system is capable of releasing energy to restore the ATP without the involvement of oxygen and is called anaerobic glycolysis. (breakdown of the glucose which causes lactic acid as a biproduct)

Lactate is reproduced in the liver to make glucose that will provide you with more energy.



this shows the breakdown process of lactic acid. carbohydrates are in the body as glycogen. the system shows the glycogen being taken down to glucose, the glucose is broke down to the pyruvic acid and then into Lactic acid.
