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 Proprioceptive Neuromuscular Facilitation (PNF).
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.
- Proprioceptive Neuromuscular Facilitation (PNF) — proprioceptive technique built on similar reflex mechanisms.
- Stretch Reflex Resetting — the complementary muscle-spindle / stretch-reflex mechanism.
