Question

A muscle contraction that results in no movement of the body is referred to as a(n) ________ contraction.

Answer 1

A muscle contraction that results in no movement of the body is referred to as an isotonic contraction. The isotonic contraction can be concentric and eccentric. Concentric contraction results in the muscle shortening, because the force the muscle is producing is greater than the resistance. Eccentric isotonic contraction on the other hand results in muscle lengthening because the resistance is being greater than the force the muscle is producing.
