What Are The Three Sources Of Energy Exercise

The aerobic energy system is also known as the oxygen energy system and it uses both carbohydrates and fat in a slow energy burn.

What are the three sources of energy exercise.

The extent to which these substrates contribute energy for exercise depends on the intensity and duration of exercise the level of exercise training the initial muscle. Muscles use the stored chemical energy of food we eat and convert that to heat and energy of motion kinetic energy. Each system uses different starting fuels each provides atp at different. Atp which stands for adenosine triphosphate is the sole source of energy for all human metabolism yet very little of this fuel is actually stored in the body.

Although muscles and engines work in different ways they both convert chemical energy into energy of motion. Atp pc anaerobic glycolysis and aerobic phosphorylation. Muscle carbohydrate stores glycogen blood sugar blood fatty acids and intramuscular triacylglycerols. Within these cells and from these energy sources adenosine triphosphate atp is formed to provide fuel.

During exercise there are four major endogenous sources of energy. The aerobic energy system is the most complex of the three using oxygen to create something called glycolysis and ultimately produce that all important atp. Most of the body s activities use a continuum of all three energy systems working together to ensure a constant supply of energy. For example during heavy exercise the body s total energy expenditure may increase 25 times above expenditure at rest 2 the body uses carbohydrate fat and protein to provide necessary energy to sustain cellular activities both at rest and during exercise 3.

Instead the body has three different systems of atp production.
