Question

Quizplus · Accepted Answer

In an isometric contraction, the muscle generates tension without any change in length, meaning there is no movement or shortening of the muscle fiber. This can occur when the muscle is pushing against a fixed object or when attempting to hold a position. Isotonic contractions involve the muscle actively shortening to move a load, while spastic and flaccid contractions refer to abnormal or dysfunctional muscle contractions.
