inhibition of the antagonist muscle group is mediated by the muscle spindle. If the agonist muscle contracts, then the spindle fires, sending messages to the spinal cord causing the antagonist muscle to relax. PNF Stretching: Autogenic Inhibition. The golgi tendon organ is a nerve receptor found in tendons.This receptor fires when tension increases within the tendon. This tension can be due to stretch or contracting muscle.o achieve this the limb is place in painfree range and an isometric contraction is sustained. The limb is then moved into the new range. The hold-relax method of PNF stretching is facilitated by the golgi tendon organ to allow a reflexive relaxation of the muscle.
PNF stretches (proprioceptive neuromuscular facilitation stretches) are a method of rapidly expanding your range of motion. While originally designed for rehabilitation, they are now used by athletes and weekend warriors as well. Weight training is one of the best methods of strength training!his style of PNF stretching is also called contract-relax-contract and contract-relax-agonist-contract (CRAC).This is very similar to the hold-relax. The therapist/helper moves the limb to the limit of its range of motion, and the patient then pushes against the therapist's resistance (for 20 seconds).
