Quizplus · Accepted Answer

During an isotonic twitch contraction, once the muscle starts to shorten, it means the force generated by the muscle has surpassed the load. The muscle will continue to shorten at a constant force level, maintaining the force required to move the load. This is characteristic of isotonic contractions, where the tension in the muscle remains constant while the muscle changes length.
