Exercise Physiology – Sources of Energy – Latest and Useful Research 2022

Exercise Physiology

During exercise physiology , the movement caused by muscle contraction requires a certain amount of energy to maintain. The direct way this energy is provided is through a chemical called adenosine triphosphate (ATP). ATP is mainly formed by the combustion and decomposition of glucose and glycogen in cells. There are two ways in the formation process, one is aerobic decomposition, and the other is anaerobic decomposition.

Aerobic decomposition

That is, in the presence of sufficient oxygen, glucose is decomposed into carbon dioxide and water within the cell, and a large amount of ATP is released for energy conversion. This aerobic breakdown is highly productive and is the primary way to provide the body with long-term energy storage. For more research click here.

Anaerobic decomposition

means that when the oxygen supply is insufficient, such as strenuous exercise physiology , certain diseases or high altitude areas, the lack of oxygen in the body will cause the muscles to mainly use the stored muscle glycogen to produce ATP. The process is as follows:

1.Muscle glycogen is first broken down into a chemical called glucose-6-phosphate.

2.This 6-phosphate glucose is then decomposed under anaerobic conditions to generate lactic acid and release a small amount of ATP.

3.Although these ATP are not enough to be generated by aerobic decomposition, it can still allow muscles to obtain a certain amount of ATP to supply the energy required for physical activities under hypoxic conditions.

4.The disadvantage of this approach is that too little ATP is produced and can only be maintained for a short period of time. For more health tips visit our site ArticlesHubs.

5.The by-product lactic acid accumulates in the muscles and causes muscle fatigue and soreness.

6.Lactic acid eventually circulates through the bloodstream into the liver, where it undergoes re-breakdown and reorganization to remove lactate and form a new source of energy.
