Question

The maximum sustained contraction of a muscle is what type of contraction?

Answer 1

Tetanus or tetanic contraction.

Explanation:

A tetanic contraction (also called a physiologic tetanic contraction to avoid confusion with the disease) occurs when the motor nerve connected to a skeletal muscle emits signals for contraction at a high rate.

This high frequency stimulation prevents the relaxation of the muscle between signals and results in a sustained contraction of the muscle to a maximum extent.
