Detailed explanation-1: -The anaerobic lactic system is possibly the most misunderstood energy system of the three. Most coaches associate the anaerobic lactic energy system with high levels of fatigue and lactate production, which is a byproduct of the anaerobic lactic system.

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: -Given the effects of exercise intensity, duration and training status on muscle glycogen utilization, it follows that glycogen depletion (in both muscle and liver) is a major cause of fatigue in both endurance and high-intensity (intermittent) type activities.

Detailed explanation-4: -The system does not use oxygen, but rather your body’s CP (creatine phosphate) stores to create energy for a short duration. Shot-putters, weight lifters, football players, gymnasts, sprint-distance runners, or any athlete that utilizes explosive movements will utilize this energy system.
