Quizplus · Accepted Answer

Running up a flight of stairs at full speed requires explosive power, which is primarily provided by fast-twitch muscles. These muscles have a greater ability to generate force quickly and effectively, which is essential for rapid movements like sprinting up stairs. Slow-twitch muscles, on the other hand, are better suited for endurance activities like long-distance running, and would not be as effective for this kind of brief, intense burst of activity. Smooth muscles and intermediate muscles are not directly involved in the kind of explosive movements required for running up stairs, and would not have as significant an impact on performance in this scenario.
