What distinguishes aerobic exercise from anaerobic exercise?

• A. Aerobic uses fats only; anaerobic uses carbohydrates
• B. Aerobic is short-duration; anaerobic is long-duration
• C. Aerobic requires oxygen; anaerobic does not
• D. Aerobic produces lactic acid; anaerobic does not

Answer: (C)

The key distinction between aerobic and anaerobic exercise lies in the requirement for oxygen. Aerobic exercise is characterized by activities that are performed at a steady intensity over an extended period, which relies on oxygen to fuel the muscles. This type of exercise primarily involves activities such as running, swimming, or cycling, where the body can take in enough oxygen to meet its energy needs. In contrast, anaerobic exercise takes place when the intensity is high, and the oxygen demand exceeds the oxygen supply. This type of exercise is typically shorter in duration and includes activities like sprinting or heavy weightlifting. The body relies on energy produced without oxygen, leading to different physiological processes and energy sources. Understanding this concept is vital for designing effective workout programs, as it allows fitness professionals to tailor exercises based on the desired energy systems and goals of participants.
