Best Answer: The ATP-PC system is use for around 10 seconds of an event, the ATP is use for 4-6 seconds before the creatine phosphate (CP) provides energy for a further 5 - 10 seconds. Weight lifting is the best example of a sport using the ATP-PC system.
Search. Known also as immediate energy system, phosphagen system, and alactic anaerobic system, the ATP â PCr system is the main energy provider for a high intensity exercise of short duration up to 10 seconds, for example lifting a weight, swinging a golf club, doing a push â up, and throwing a hammer.TP (adenosine triphosphate) is the primary energy currency of the body and when hydrolyzed, it releases a lot of energy that results in muscle contraction and protein synthesis. In fact, ATP is the stored form of energy readily available for the body to produce heat and energy when reacting with water.
