Have you ever heard of creatine? Many athletes now use a dietary supplement called creatine to enhance their performance. Although muscle cells contain only enough ATP for a few seconds of intense activity, most have a reserve nearly twice as large in the form of a molecule called creatine phosphate. When the muscle goes to work and starts to use up its available ATP, phosphates are transferred from creatine phosphate directly to ADP, regenerating ATP in a matter of milliseconds. More creatine, more muscle activity.
