What characterizes anaerobic exercise?

Anaerobic exercise is characterized by activities that are high in intensity but occur in short bursts, where oxygen supply is limited. This type of exercise relies on energy sources stored in the muscles, rather than oxygen, making it suitable for activities such as sprinting, heavy weightlifting, and high-intensity interval training. The energy is derived from anaerobic pathways, which do not require oxygen, allowing for brief, powerful exertions.

This sets anaerobic exercise apart from aerobic exercise, which requires a continuous supply of oxygen and is sustained over a longer duration. Hence, activities associated with aerobic exercise would not match the high-intensity, short-duration nature of anaerobic workouts. Focusing on endurance or performing at a moderate pace generally corresponds more to aerobic exercise, as they prioritize sustained energy use and greater oxygen consumption over time.
