Final answer:
Distance running is not an example of an anaerobic exercise; it is an aerobic activity that involves sustained energy output over an extended period unlike the high intensity, short duration activities of anaerobic exercises.
Step-by-step explanation:
Which of the following is not an example of an anaerobic exercise? The answer is distance running. Anaerobic exercises are characterized by high intensity and short duration, utilizing fast-twitch muscle fibers and a small amount of oxygen. Common examples include sprints, high-intensity interval training (HIIT), and strength training. In contrast, distance running is an aerobic activity, where muscles are used well below their maximum contraction strength for a long period, consuming a large amount of oxygen.
