Muscle spindles cause two things to happen: 1) the muscle being stretched (agonist) contracts to prevent you from going too far too fast in that stretch; and 2) the opposing muscle force (antagonist) is inhibited (prevented from contracting) so that that muscle doesnât pull that stretch further.he muscle spindleâs reflex contraction of its associated muscle simultaneously causes the antagonist muscle group to relax, which is called reciprocal inhibition. The muscle spindle serves as an alert to the muscles; they are located in the muscle belly and sense muscle stretch.
