In one line

The GTOs are proprioceptors whose firing during a sufficiently long-held stretch induces muscular relaxation — one of the advantages that makes static stretching effective.

Detail

The source describes the role of the Golgi tendon organs (GTOs) in the context of static stretching: static stretching "can induce muscular relaxation via the firing of the GTOs if the stretch is held long enough." Thus, holding a stretch long enough allows the GTOs to fire, producing relaxation of the stretched muscle. This GTO-mediated relaxation is one of the listed advantages of static-stretching, and the proprioceptive basis is also exploited by pnf-stretching.

Key facts

  • GTO = Golgi tendon organ.
  • GTOs fire when a stretch is held long enough.
  • GTO firing induces muscular relaxation of the stretched muscle.
  • This relaxation is a listed advantage of static stretching.

Connections

  • static-stretching — GTO firing induces relaxation when the stretch is held long enough.
  • pnf-stretching — proprioceptive technique built on similar reflex mechanisms.
  • stretch-reflex-resetting — the complementary muscle-spindle / stretch-reflex mechanism.

Proprioceptive Neuromuscular Facilitation (PNF)
A range-of-motion strategy (also called a muscle energy technique) originally developed for rehabilitation; its two most common forms are the contract-relax and the contract-relax-contract techniques.
Static Stretching
Stretching to the farthest point and holding the position — the safest technique, requiring the least energy and giving time to reset the stretch reflex, change length, and relax the muscle via the GTOs.
Stretch Reflex Resetting
When a muscle is stretched suddenly the stretch reflex makes it contract, but training can raise the threshold at which the reflex fires, letting the muscle relax further into the stretch.
