Question

Quizplus · Accepted Answer

When a muscle contracts and lengthens, it is known as an eccentric contraction. This type of contraction occurs when there is tension on the muscle, but the muscle is still lengthening. This is different from a concentric contraction where the muscle shortens while under tension and from an isometric contraction where there is tension on the muscle but no change in length.
