What Are The Three Sources Of Energy Exercise
Atp pc anaerobic glycolysis and aerobic phosphorylation.
What are the three sources of energy exercise. Muscle carbohydrate stores glycogen blood sugar blood fatty acids and intramuscular triacylglycerols. Although muscles and engines work in different ways they both convert chemical energy into energy of motion. 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. 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.
Instead the body has three different systems of atp production. Muscles use the stored chemical energy of food we eat and convert that to heat and energy of motion kinetic energy. Most of the body s activities use a continuum of all three energy systems working together to ensure a constant supply 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.
The aerobic energy system is also known as the oxygen energy system and it uses both carbohydrates and fat in a slow energy burn. Exercise poses a major challenge to the various bioenergetic pathways in the working muscle 2. Each system uses different starting fuels each provides atp at different. The body uses 3 different systems to supply cells with the necessary atp to fuel energy needs.
During exercise there are four major endogenous sources of energy.
