Definition of "phosphagen" []

• Any of a class of energy storage compounds, chiefly found in muscular tissue in animals, allowing a high-energy phosphate pool to be maintained in a concentration range, which, if it all were ATP, would create problems due to the ATP consuming reactions in these tissues. (noun)

• "These calories are used to: replenish your glycogen (the way you store fuel in your muscles and liver) and oxygen stores. resynthesize phosphagen (ATP-PC). remove lactate. repair the wear and tear on your muscles caused by exercise (and these patch kits are made up of protein, which is costly in terms of calories). return your increased ventilation, blood circulation and body temperature to pre-exercise levels. hormones exercise induces (which also require protein)."
• "For example they detail the role of the phosphagen, glycolytic and mitochondrial systems in producing ATP and the differences in how each manages any released protons."
• "Mike Caviston: Performance over 2K depends on the ability to do two things: 1) produce large amounts of energy (via the phosphagen, glycolytic, and oxidative pathways) and 2) resist fatigue (by disposing of the byproducts of intense muscular contractions, such as hydrogen ions, potassium ions, and ammonia)."
