WebbBecause of their slow contractility and a large amount of ATP being produced, Type 1 muscle fibers (slow twitch) can easily resist fatigue. They are focused on aerobic … WebbSlow Twitch Muscle Fibers (Type 1) These fibers specialize in low-intensity sustained activity, such as riding at an easy endurance pace. They contain lots of mitochondria, which they use to efficiently fuel themselves through aerobic metabolism. If properly fueled they can sustain almost indefinitely, but they can not exert high force.

What’s the Difference Between Fast- and Slow-Twitch Muscles?

WebbHuman muscle fibers are generally classified by myosin heavy chain (MHC) isoforms characterized by slow to fast contractile speeds. Type I, or slow-twitch fibers, are seen in high abundance in elite endurance athletes, such as long-distance runners and cyclists.
