Annotation rationales
Type-II fast skeletal muscle fibres are specialized for rapid, high-force contraction with subtype-dependent glycolytic or oxidative capacity.
Functional implications
They power brief and intense movements and provide adaptable force output at the cost of lower fatigue resistance in the most glycolytic fibres.
