What type of contraction resists movement caused by another force?

The type of contraction that resists movement caused by another force is an isometric contraction. During an isometric contraction, the muscle generates tension while maintaining a constant length, meaning it does not shorten or lengthen despite the application of external forces. This type of contraction is often seen when a muscle engages to stabilize a joint or maintain a position against an opposing force, such as when holding a weight in place or pushing against an immovable object.

Eccentric contractions involve lengthening of the muscle under tension, while concentric contractions involve shortening of the muscle. Isokinetic contractions occur at a constant speed throughout the range of motion, which is not applicable in the context of resisting an external force without movement. Thus, an isometric contraction is the appropriate choice for describing a situation where muscles resist movement without changing length.
