Anaerobic exercise is characterized by which of the following?

Anaerobic exercise is characterized by which of the following?

• A. Long-duration endurance activity
• B. Steady-state aerobic exercise
• C. Short-duration exercise such as weight lifting and sprinting
• D. Low-intensity cardio

Answer: (C)

Anaerobic exercise involves very high-intensity efforts that are short in duration, so energy is produced primarily without relying on oxygen. The body uses stored quick-energy systems—the ATP-PC (phosphagen) system and anaerobic glycolysis—to generate power for brief bursts. This fits activities like weight lifting and sprinting, where you generate a lot of force quickly and fatigue quickly as these stores deplete and lactate builds up. The other options describe activities that rely mainly on aerobic metabolism, supporting longer, steady, lower-intensity efforts. So the short-duration, high-intensity nature of the effort makes this option the correct characterization.
