Energy system 1: ATP - PC system
The ATP-PC system can provide enormous amounts of energy, but only for
short bursts of activity.
PC commonly known as creatine phosphate (CP) or phosphocreatine [1] or
alactic system] CP is made up of a complex creatine molecule with one bond
to a phosphate molecule.
Creatine phosphate molecules are stored in the muscle and can break down
to give energy.
The energy produced is used to convert ADP back to ATP. Because PC is
stored in the muscle and breaks down easily, the ATP-PC system can provide
enormous amounts of energy very quickly.
Its drawback is that there is only about 10 seconds' worth of energy
available before it runs out.
The reason it is called ATP-PC system is because both ATP and PC are
stored in the muscle. The first muscular contraction occurs with energy
released from ATP to ADP. This is quickly followed by the breakdown of the
PC molecule that comes into play and supplies the energy for the next 10
seconds or so for ADP to reconvert, thus allowing ATP to be broken down
again.
* provides energy for short, high intensity, explosive events lasting
from 0-10 seconds
* takes approximately 3 minutes for this system to fully recover before
it can be used again; 70% recovery occurs after approximately 30 seconds
* this system supplies energy for sprints, jumps, throws, and kicks - any
activity that is short in duration and requires maximal or near maximal
effort

ATP-PC system is only for short period maximum energy supply. 10 second for energy supply, 30 second to become ready for 70%, 3 minute to fully recover. Suitable for high intensity training.
