Energy systems provide the energy required by muscles for movement. The body requires energy to be in the form of Adenosine Tri-Phosphate (ATP) in order to convert it from chemical energy to mechanical (movement) energy.
ATP = ADP + P + ENERGY:
This also requires energy. There are 3 ways the body has of replacing the phosphate, which are the 3 energy systems or energy pathways. Which of the 3 ways our body will use for the ATP to be rebuilt from ADP depends on the type of activity you are performing, the intensity, and the duration.S
The answer lies in bioenergetics, that is, the network of energy systems the body uses to deliver ATP to the muscle cells. There are three major types of energy systems: … Aerobic (oxidative) glycolysis — the use of oxygen as fuel to breakdown carbohydrate and fat into ATP; low energy output, long duration.
What are the 3 types of energy systems?
Learn about the three major systems are energy:
- Anaerobic – Phosphocreatine (PCr) System (ATP; triphosphate, as in three phosphates)
- Glycolytic or Lactic Acid System.
- Aerobic System.
The two systems of anaerobic energy systems are: High energy phosphates, adenosine triphosphate and creatine phosphate – called “alactic anaerobic“. Anaerobic glycolysis – called “lactic anaerobic“.
As the fastest way to resynthesize ATP, the phosphagen system is the predominant energy system used for all-out exercise lasting up to about 10 seconds.
