activity: the phosphagen system, the glycogen lactic acid system and the aerobic system. Creatine phosphate is part of the phosphagen system and concerns the metabolism of ATP. ATP (adenosine
triphosphate) is the basic source of energy for muscle contraction (Saunders, 1996). When one phosphate radical is removed from this molecule, 7300 Calories of energy is released, which can
then be utilized to energize the muscle contractile process (Saunders, 1996). When the second phosphate radical is removed, another 7300 calories becomes available. Removal of the first phosphate converts ATP
into ADP (adenosine diphosphate) and remove of the second converts ADP to AMP (adenosine monophosphate) (Saunders, 1996). The amount of ATP present in the muscles, even for an extremely well-conditioned
athlete, is adequate for sustaining muscle power for about three seconds (Saunders, 1996). Therefore, the production of ATP must be continuous. This is where phosphocreatine, otherwise known as creatine
phosphate, comes into the picture, as this is another chemical compound that possesses a high energy phosphate bond (Saunders, 1996). Creatine phosphate (PO3) has a structure that can breakdown into
creatine plus a phosphate ion, creatine - PO4 (Saunders, 1996). When this takes place, a large amount of energy is released. The high energy phosphate bond of creatine phosphate has
more energy than the bond of ATP -- 10,300 calories per mole, which contrasts to ATPs 7300 (Saunders, 1996). Therefore, creatine phosphate has enough energy to reconstitute the high energy
bond of ATP (Saunders, 1996). The majority of muscle cells have two to four times as much creative phosphate as they do ATP. A crucial fact to physical performance is
that the energy transference from creative phosphate to ATP takes place within a fraction of a second (Saunders, 1996). This means that all of the energy in the muscle that
