In isometric contraction, what happens to the joint angle?

  1. The joint angle increases

  2. The joint angle decreases

  3. The joint angle remains unchanged

  4. The joint angle changes but does not do work

The correct answer is: The joint angle remains unchanged

In isometric contraction, the muscle generates tension without changing its length, which means that there is no movement of the joint. This type of contraction occurs when a muscle is engaged against an immovable object or when opposing forces are equal, causing the muscle to tighten but not shorten or lengthen. As a result, the joint angle remains unchanged during this contraction. Understanding isometric contractions is essential because they are often used in rehabilitation and strength training programs to build muscle strength while minimizing joint movement. This can be particularly beneficial for individuals recovering from injuries or those with joint concerns, as it allows for muscular engagement without putting stress on the joint.
