In which type of contraction is a force exerted by the muscle but the muscle does not shorten?

Question

Quizplus · Accepted Answer

In an isometric contraction, the muscle is generating force but there is no change in the length of the muscle. This can occur when the muscle is pushing against a fixed object or when the force generated by the muscle is not enough to overcome the resistance being applied. In contrast, isotonic contractions involve a change in muscle length as the muscle exerts force to move a load.
