What type of exercise is described as anaerobic?

Anaerobic exercise is characterized by short bursts of high-intensity activity where the body's demand for oxygen exceeds the oxygen supply available. This type of exercise relies primarily on energy sources stored in the muscles, rather than using oxygen to fuel the activity. High-intensity sprinting is a perfect example of anaerobic exercise, as it involves exerting maximum effort over a short duration. During a sprint, the body utilizes stored ATP and creatine phosphate for immediate energy, allowing athletes to achieve peak performance for a brief time.

In contrast, the other types of exercises listed predominantly incorporate aerobic activity. Long-distance running and swimming usually require a steady supply of oxygen to fuel the body over extended periods, while yoga generally emphasizes flexibility, concentration, and breath control rather than pushing the body to its anaerobic threshold. Thus, high-intensity sprinting clearly fits the definition of anaerobic exercise due to the intensity and duration of effort involved.
