Energy for the muscles
creatine is a body's own substance composed of amino acids. It is of fundamental importance for the body's own energy production and storage. Creatine acts like an ""energy buffer"", i.e. it helps to keep the energy supply of the muscles constant during training. Adenosine triphosphate (ATP) is the molecule that our body uses as an energy source for almost all metabolic reactions, including muscle contraction.
The compound ATP is cleaved into adenosine diphosphate (ADP) after its use and thus after fulfilling its function as an energy carrier. However, in order to cover the further energy requirements of the cells, ADP must be constantly converted back into ATP. Creatine comes into play during this regeneration of ATP.
Creatine occurs in the muscles in the form of phosphocreatine (or creatine phosphate) and has the function of loading the ADP with phosphate there, whereby ATP is produced again, which our body immediately uses for energy purposes.
Simply expressed when we express physical activity – especially at a high intensity level – our body consumes large amounts of ATP in a short time. Creatine in this context has the important task in the form of creatine phosphate to make the energy supplier ATP quickly available again for our muscles.
Creatine in diet
The word “creatine“ comes from Greek and means as much as “meat“. This is because the body's own substance is found primarily in meat and muscle tissue. The human body can produce limited amounts of creatine itself and stores it mainly in the skeletal muscles.
Since creatine is mainly found in animal foods, it is popular with vegans and vegetarians. Also sportsmen protect Creatin due to its function in the energy supply of the muscles as food supplements. Especially in sports with short, intensive physical exertion, such as weight lifting, running (100, 200 or 400 m), swimming (50-100 m) and cycling (time trial), supplementation with creatine can be useful. Because with short, intensive training Creatin has starting from a quantity of 3 g daily a performance-enhancing effect.
