What Are The Three Sources Of Energy For Humans During 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 for humans during exercise.

Our ability to run bicycle ski swim and row hinges on the capacity of the body to extract energy from ingested food. Instead the body has three different systems of atp production. Aerobic glycolysis has a slow rate of atp production and is predominantly utilized during longer duration lower intensity activities after the phosphagen and anaerobic systems have fatigued. Energy system one aerobic.

Atp pc anaerobic glycolysis and aerobic phosphorylation. Albert einstein in his infinite wisdom discovered that the total energy of an object is equal to the mass of the object multiplied by the square of the speed of light. As potential fuel sources the carbohydrate fat and protein in the foods that you eat follow different metabolic paths in the body but they all ultimately yield water carbon dioxide and a chemical energy called adenosine triphosphate atp. The body uses carbohydrate fat and protein to provide necessary energy to sustain cellular activities both at rest and during exercise 3.

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. It is important to remember that all three of these systems contribute to the energy needs of the body during physical activity. 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.
