Control of muscle tension common in the muscles of the hand and forearm responsible for grip using the above example, the muscle contraction required to grip but not move a heavy object prior to lifting would be isometric. Best answer: an isometric contraction of a muscle generates force without changing length an example can be found when the muscles of the hand and forearm grip an object the joints of the hand do not move, but muscles generate sufficient force to prevent the object from being dropped.
