The isometric contraction showed that when the brain is occupied by an action the reflex arc will then take over and allow a different muscle to still contract. The Jendrassik maneuver was shown to decrease the response component from the onset of the stretch in both extensor and flexor muscles (Nardone & Schieppati, 2008). In the experiment it did slow the action potential velocity down to close to the same value as when the tendon was struck relaxed. As the stimulus on the tendons increases in amplitude it was shown the that action potentials had a faster velocity speed but did not change the amplitude of the action
