A store of energy-giving phosphate in muscles.
A high-energy compound in muscle which has a higher phosphate group transfer potential than ATP. It acts as a reservoir for phosphate so that the muscle can maintain a steady level of ATP to support muscle contraction. It also serves this function in nerve so that a steady supply of ATP for nerve conduction is provided.
Chemical present in muscles that makes ATP rapidly for 30 seconds’ worth of exercise. Creatine phosphate is produced in the body from the digestion of meat. It can also be found as a supplement. Research is inconclusive as to its benefits or long-term risks.
