What term describes a muscle maintaining tone through range of motion?

Explanation:
Isotonic contraction describes producing force while the muscle changes length as the joint moves through a range. This keeps the muscle under tension while lengthening or shortening, allowing movement across the ROM. Concentric and eccentric are specific forms of isotonic contractions (shortening and lengthening, respectively). In contrast, isometric contractions generate force without changing length, so there’s no movement through the range.
