The main energy supply system for 400-meter running is phosphate system. The energy supply system provides less energy, and the contraction of skeletal muscle in a few seconds can consume the energy provided by this system. Protophosphoric acid system (ATP-CP system) usually refers to a system composed of ATP and creatine phosphate (CP). Because their chemical structure belongs to high-energy phosphate compounds, they are called orthophosphate systems.

Such as creatine phosphate and arginine phosphate, supply high-energy phosphate bonds through ATP/ADP system (adenosine monophosphate system) and store high-energy phosphate bonds in organisms, especially muscles, through the same system. These compounds are collectively referred to as phosphatoprotein.

Extended data

The structural similarity of phosphorus compounds lies in the high-energy phosphate bond on guanidine group. In addition, it also exists in nervous tissue, generator palace and other tissues. As for comparative physiology in phosphagen, there are creatine phosphate in vertebrates, cephalopods and hydralisks, arginine phosphate in uropoda, arthropods, mollusks and some echinoderms, and creatine phosphate and arginine phosphate in echinoderms (sea urchins).
