Detailed explanation-1: -The primary energy source for sprinting distances up to 400 meters, then, is Phosphocreatine. From 400 meters to 1, 500 meters, it’s anaerobic glycolysis. For distances longer than 1, 500 meters, athletes rely primarily on aerobic metabolism.
Detailed explanation-2: -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-3: -For a 400 m race, the most predominant energy system used by elite athletes is anaerobic glycolysis. This energy system can last from 30 to 40 s when trained, almost long enough to complete the entire race which takes the very best athletes between 44 to 50 s to complete.
