WebApr 13, 2024 · ATP-Phosphocreatine (ATP-PCr) System. The ATP-PCr system is mainly used for short, intense bursts of energy such as a 40-yard dash or a maximal exercise lasting about 1-10 seconds. This system is anaerobic meaning it does not require oxygen. Anaerobic contractions occur when you are performing a high-intensity exercise at 80 … WebThe phosphagen system consists of the ATP store and the phosphocreatine (PC) (also called creatine phosphate) store (see upper section of Fig. 8-1). 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. WebAccording to the creatine kinase–phosphocreatine energy-shuttle hypothesis, 30 phosphocreatine serves to transfer the high-energy phosphate bond from the site of ATP production (mitochondria) to the site of ATP utilization (myofibrils). During metabolic stress, this energy shuttle becomes essential for maintaining high-performance states. crysis baixar
