Web26 de mar. de 2016 · Type IIb: Type IIb motor units are very prone to fatigue, but they produce the most force when stimulated. These are the last motor units recruited when a muscle gets activated, and they’re the first to stop being recruited when the force from a muscle is no longer needed. Type IIb are sometimes called Type IIx in human muscle.
