In an Isotonic Contraction,the Origin Point Moves Toward the Insertion

Question

In an isotonic contraction,the origin point moves toward the insertion point.

Accepted Answer

In an isotonic contraction, the tension generated by the muscle is constant but the length of the muscle changes. The origin and insertion points may remain fixed, or the insertion point may move toward the origin point. However, it is not true that the origin point moves toward the insertion point in an isotonic contraction.
