Is anaerobic activity typically long or short duration?

Anaerobic activity is characterized by high-intensity efforts that occur in short bursts, typically lasting from a few seconds to a couple of minutes. This type of exercise does not rely on oxygen for fuel but instead uses energy stored in the muscles, leading to quick fatigue. Common examples include sprinting, heavy weightlifting, or high-intensity interval training (HIIT).

The nature of anaerobic activities involves rapid energy expenditure that cannot be sustained for long periods, making short duration the defining aspect of this type of exercise. This contrasts sharply with aerobic activities, which are designed to be maintained over longer periods and rely heavily on oxygen for energy.
