Creatine monohydrate is converted to creatine phosphate (CrP) in muscle tissue. CrP provides a critically important store of energy which helps to power short bursts of intense muscular activity, as in sprinting or weightlifting. CrP is used up in regenerating the ATP consumed during intense exercise, and is itself renewed when creatine interacts with ATP during the rest period immediately after strenuous exercise.
