Question

question 4
a static muscle action is:
○ concentric
○ eccentric
○ isometric
○ isotonic

Explanation:

A static muscle action occurs when the muscle contracts but there is no change in muscle length. Isometric contractions are static, as the muscle exerts force without changing its length. Concentric and eccentric are dynamic muscle - actions where muscle length changes. Isotonic contractions involve movement and change in muscle length.

Answer:

C. Isometric
