Smooth muscle responsible for sustained contractions in the blood vessels, gastrointestinal tract, and other areas in the body.

Put simply, stress and anxiety cause grinding of teeth and sustained muscular contraction in the face.

While usually painless, in some instances the sustained contraction and abnormal posturing in dystonia may cause pain.

Renshaw cells are more inhibited at the same level during a dynamic contraction compared with sustained contraction.

These sustained contractions of muscle sarcomeres compresses local blood supply restricting the energy needs of the local region.

This technique utilizes the golgi tendon organ, which relaxes a muscle after a sustained contraction has been applied to it for longer than 6 seconds.

Glycogen can be rapidly converted to glucose when energy is required for sustained, powerful contractions.

They can do a short, single contraction (twitch) or a long, sustained contraction (tetanus).

In cases such as this, the sustained contraction lacks any relaxation, and it is called a tetanic contraction.

Tonic vibration reflex is a sustained contraction of a muscle subjected to vibration.
