The ATP molecule is then unable to provide energy to the working muscles. To continue the muscular movement ‚ the body relies on creatine phosphate (PC) in a secondary reaction. This system is used for short bouts of exercise. Especially those lasting up to 12 seconds. the lactic acid system will continue
