Question: 1 / 400

Which of the following is considered a type of anaerobic exercise?

Long-distance running

Cycling at a steady pace

Weightlifting

Weightlifting is classified as a type of anaerobic exercise because it involves short bursts of high-intensity effort that are primarily fueled by energy systems operating without sufficient oxygen. This form of exercise relies on the immediate energy provided by the phosphocreatine system and the anaerobic glycolytic pathway, which both support activities that last from a few seconds up to a couple of minutes.

In contrast, long-distance running and cycling at a steady pace are primarily aerobic activities, where the body utilizes oxygen to produce energy over extended periods. Swimming can also be a mix of both aerobic and anaerobic depending on the intensity and distance but is generally more aerobic when done at moderate to long distances. Hence, weightlifting's characteristics of short duration and high intensity distinctly categorize it as anaerobic exercise.
