Detailed explanation-1: -Its estimated that during sprint events approximately 95% of energy production comes via the anaerobic system (85% phosphate, 10% anaerobic glycolysis), and only 5% from aerobic oxygen. Thus, the 100m sprint is an anaerobic event relying heavily on energy supply from the ATP-PC system!
Detailed explanation-2: -Creatine-P helps maintain a constant concentration of ATP in muscle during sudden bursts or exercise that would otherwise deplete ATP concentration in the cell.
Detailed explanation-3: -The resynthesis of CP during recovery normally occurs rapidly, but is totally inhibited if the local circulation to the muscle is occluded. The limiting factor for CP resynthesis which could be a low intramuscular pH or availability of oxygen has been investigated in the present study.
