Phosphocreatine (PCr) is a key constituent of the creatine kinase reaction, an integral process in the rephosphorylation (formation) of Adenosine Triphosphate (ATP). ATP is one of the key metabolites for energy production in the body, therefore through promoting the resynthesis of ATP we can increase our capacity to train. Phosphocreatine stores are limited in the body meaning it only delivers energy for a short period of time, this makes it highly beneficial to short burst, high intensity, power exercises lasting approx 6-10 seconds.
So in order to improve explosive power and endurance movements such as plyometrics, leaps, bounds and jumps, or short burst loads i.e. bench press etc then creatine monohydrate may be of interest to you.
