This occurs when a concentrically contracting muscle becomes too shorted and can no longer maintain or increase force production.

• Passive insufficiency

• Creep

• Active insufficiency

• Force-velocity relationship

Force production increases even when the muscle surpasses its optimal resting length due to the stored energy from the non-contracile proteins.
