What type of contraction involves movement with the muscle tension remaining unaltered?

Explanation:
Isotonic contraction is when a muscle changes length while producing a relatively constant level of tension, so movement occurs. This means you lift or lower a load as the muscle shortens (concentric) or lengthens (eccentric) while the force remains roughly the same. In contrast, isometric contraction generates tension without any change in length, so there’s no movement. So, moving a limb with steady tension describes an isotonic action.
