WebSlow-twitch muscle fibers (also known as “type I,” or “MHC I”) are responsible for longer-duration, lower-effort activities like jogging and cycling. MHC I’s are more fatigue … WebType IIx are best known as fast-twitch muscle fibers. These are the muscle fibers primarily responsible for fast, explosive movements like sprinting. However, they lack the endurance-boosting ability of slow-twitch fibers and can only be used for short periods of time. Type IIa are what we call intermediate fibers.

WebGenerally, fast twitch fibers generate high force for brief periods of time. Slow twitch fibers generate lower amounts of force but can do so for longer periods of time. Intermediate fibers have some characteristics of both fast and slow twitch fibers. Fast twitch fibers are also called Type II fibers.
