What is the peak duration for the anaerobic glycolytic system to exert its power?

The peak duration for the anaerobic glycolytic system to exert its power is typically around 15 seconds. This energy system primarily uses carbohydrates to produce ATP through anaerobic metabolism, which is essential during high-intensity efforts that last from about 10 to 30 seconds. During this time frame, the body can generate energy rapidly, but it cannot sustain this power output beyond this duration without significant fatigue setting in due to the accumulation of lactate.

The anaerobic glycolytic system is crucial for activities like sprinting or intense interval training, where the body relies on stored glucose without the need for oxygen, creating energy quickly but also leading to lactate production that eventually inhibits performance. Therefore, understanding that the peak performance of this system lies within that 15-second mark helps in programming effective training sessions and optimizing performance for activities that require maximal short-term efforts.
