Detailed explanation-1: -If the ATP-PC system is used for longer than 10 seconds it becomes depleted. Therefore, if the centre remains at a high intensity for greater than 10 seconds or short efforts are repeated between 85-95%MHR the Anaerobic Glycolysis system becomes dominant.
Detailed explanation-2: -The ATP-CP system is the system that is responsible for very short (i.e. 1-2 repetitions), explosive movements. This energy system is only good for about 6-10 seconds of activity. Using cars as an analogy, the ATP-CP system would be your nitrous boost.
Detailed explanation-3: -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.
