How long should anaerobic exercise bursts generally last?

Anaerobic exercise bursts are characterized by high-intensity efforts that primarily rely on the energy stored in muscles, rather than oxygen. These exercises typically include activities like sprinting, heavy weightlifting, or high-intensity interval training (HIIT). For anaerobic activities, the duration of exertion is generally short, with effective bursts lasting between 1 and 25 seconds. This time frame allows athletes to perform at peak intensity before lactic acid builds up, leading to fatigue.

In this context, duration plays a crucial role in maximizing performance and energy output. Short, explosive efforts allow for maximal power and strength without the significant drop in performance that longer durations would incur, which supports muscle development and improves overall fitness.
