What is Creatine?
Creatine is a compound that can be made in our bodies or taken as a dietary supplement. The chemical name for Creatine is methyl guanidine-acetic acid. That sure is a mouth full - which is why it is much easier to just call it creatine. Here is the chemical makeup of creatine - - How much Creatine do we have in our body?
- Where is Creatine stored in our body?
- What is ATP?
To meet the demands of a high-intensity exercise, such as a sprint, muscles derive their energy from a series of reactions involving adenosine triphosphate (ATP), phosphocreatine (PCr), adenosine diphosphate (ADP), and creatine. ATP, the amount of which is relatively constant, provides energy when it releases a phosphate molecule and becomes ADP. ATP is regenerated when PCr donates a phosphate molecule that combines with ADP. Stored PCr can fuel the first 4-5 seconds of a sprint, but another fuel source must provide the energy to sustain the activity. Creatine supplements increase the storage of PCr, thus making more ATP available to fuel the working muscles and enable them to work harder before becoming fatigued.
