Quizplus · Accepted Answer

Going for a long run primarily uses Type I (slow twitch) muscles, which rely on aerobic metabolism for energy production. This is because aerobic metabolism is better suited for activities that require endurance, such as long-distance running. Fast twitch (Type II) muscles, on the other hand, rely more on anaerobic metabolism and are better suited for short, intense bursts of activity. Therefore, options A and B are incorrect. Option D is also incorrect because Type I muscles primarily use aerobic metabolism.
