Question

Quizplus · Accepted Answer

Weight lifting requires short bursts of intense effort, which is dependent on fast-twitch muscle fibers. These fibers have high levels of energy production and fatigue quickly, but can generate high levels of force. Running marathons, on the other hand, requires a lot of endurance, which is only possible with slow-twitch muscle fibers. These fibers are designed for long-term energy production and do not fatigue easily. Therefore, a person who excels at weight lifting but not at marathon running is likely to have a higher percentage of fast-twitch muscle fibers in their leg muscles.
