Slow-twitch muscle fibers have a high resistance to fatigue.

True

Explanation:

Most muscles contain some of them but the proportion depends on both the muscles and the individuals. The fast contraction fibers are long and pale, while the slow contraction fibers are small and red. The color is due to the slow contraction fibers having a high content of myoglobin (hemoglobin), these fibers tend to be more abundant in the muscles responsible for activities of low tension but high continuity such is the case of marathon runners and background, they are muscles of slow fatigue and are important in any activity that requires resistance.

Rapid contraction fibers (white) predominate in muscle used for those activities where great forces need to be developed, they are fibers as the name implies of rapid, powerful and rapid fatigue contractions, predominate in athletes competing in speed strength activities and short duration.
