Physiological Principles of PNF Stretching

A step-by-step understanding of exactly what happens in your muscle during a PNF stretch.

The muscle spindle is a receptor found within a muscle, which is made up of unique muscle fibers, sensory endings, and motor endings. The purpose of the muscle spindle is to prevent over-stretching of the muscle in which they are contained. When a muscle is put on stretch, the sensory endings in the spindle are activated and in turn send a message to the muscle telling it to contract. This contraction prevents the muscle from stretching into a plastic stage and attempts to prevent tearing of the muscle.

The GTO, on the other hand, works to relax a muscle so that the stretch being applied does not cause tearing or overactivity of the nerve fibers. These structures are found attached to the fibers of the tendons of a muscle. The GTO structure is made up of sensory nerve afferent fibers, which are very sensitive to the changes in tension of the tendon.

When a muscle is put on stretch for a prolonged amount of time or contracts isometerically, the GTO is activated and inhibits the tension, allowing the muscle to relax and elongate. This elongation during a stretch or extreme tension helps prevent the possible tearing of a tendon or muscle. This process is known as autogenic inhibition.

Reciprocal inhibition is the physiological process that occurs when the agonist muscle concentrically contracts, causing the antagonist muscle to in turn relax. This relaxation of the antagonist muscle allows the agonist muscle to move the limb through the total allowed range of motion without interfering tension.

PNF stretching mainly focuses on the principle of reciprocal inhibition. As the antagonist muscle of the limb being stretched contracts, the agonist muscle relaxes and increases its flexibility. This process is used specifically in the contract-relax technique of PNF stretching. The contract-relax pattern causes neural responses that inhibit the contraction of the muscle being stretched. The principle of autogenic inhibition is found specifically in the slow-reversal-hold-relax technique of PNF stretching. Here, the sustained isotonic contraction by the antagonist muscle increases tension in the muscle and tendons, which stimulate the GTO.

Once a muscle that was performing an isometric stretch relaxes, it gains the ability to stretch beyond its initial length. PNF stretching attempts to increase the muscle's range of motion by immediately passively stretching the just contracted muscle. This stretching of the previously isometrically contracted muscle helps to train the muscle's stretch receptors in the muscle spindle to immediately accommodate a greater muscle length. Also, the prolonged, intense contraction fatigues the fast-twitch muscles. This makes it harder for the fibers to contract in resistance to the stretch.
