Creatine Phosphate Energy System

The creatine phosphate system is used at the highest intensity exercise given by the person exercising.

Creatine phosphate energy system. This is an energy system your body will put to use in certain types of training. The cp system is generally used in short highly explosive training. Together the atp levels and creatine phosphate levels are called the phosphagen system. The energy system that uses atp and creatine phosphate fuel the body for long exercise sessions.

The phosphagen system can supply the energy needs of working muscle at a high rate but only for 8 to 10 seconds. To rapidly replenish atp muscle cells break down another high energy compound called creatine phosphate cp. The main fuel for this system will be glycogen that we store in the muscles and the liver as well as creatine phosphate. This is called the atp cp or phosphagen energy system sometimes referred to as the.

Phosphocreatine also known as creatine phosphate cp or pcr pcr is a phosphorylated creatine molecule that serves as a rapidly mobilizable reserve of high energy phosphates in skeletal muscle myocardium and the brain to recycle adenosine triphosphate the energy currency of the cell. Pcr is broken down releasing a phosphate and energy which is then used to rebuild atp. As the muscle continues to work the creatine phosphate levels begin to decrease. The phosphagen system consists of the atp store and the phosphocreatine pc also called creatine phosphate store see upper section of fig.

This is referred to as the creatine phosphate pcr system the atp pcr system or simply the phosphagen system. Creatine phosphate energy system. True o false muscle strength improvements in the first few weeks of a program are due to. Atp and creatine phosphate also called phosphocreatine or pcr for short make up the atp pcr system.

Recall that atp is rebuilt by adding a phosphate to adp in a process called phosphorylation. These two will work in different systems and at different times to quickly produce energy. The atp store in the body is small and is sufficient to allow maximal effort for about 1 to 2 seconds but there are ways of providing more atp to replace that being used during metabolism. The system relies on the fuel carbohydrates to further its work at providing energy the use of this system is limited due to the fact that there is only a small amount of creatine phosphate in the muscle cell thus meaning that when it.

We are going to start by covering the energy system responsible for the provision of energy during short explosive bouts. Increased size of muscle fibers. Increased activation and coordination of motor units. Creatine phosphate is your body s simplest most immediate energy source and your body maintains using this system for a short period of time.

You are then left with adenosine di phosphate adp.
