Detailed explanation-1: -The ATP-PC system provides an immediate and intense short burst of energy, useful in sports such as 100m sprints, Powerlifting, or throwing events such as the Javelin, Shot Put, or Discus throw, but is only useful for around 10 seconds.

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: -The ATP-PC System lasts for 6-10 seconds and is used during maximal power output exercises such as all-out effort sprints, jumps, 1RMs etc. It’s the simplest energy production process, as it enables a fast muscle contraction. There is also no acidic by-product, which usually causes fatigue.

Detailed explanation-4: -Athletes who compete in sports that require high amounts of short duration acceleration – power lifters, 100m sprinters, or discus throwers use the anaerobic a-lactic system.

Detailed explanation-5: -ATP-PC System It is the system that is called upon for short bursts of intense activity, such as those lasting up to 10 seconds. In the sports world, these activities could include shot-putting, weight lifting, or those where sprinting for very short periods of time is required.
