autogenic inhibition

autogenic inhibition

A sudden relaxation of muscle in response to high-magnitude tension, which is an autogenic inhibitory negative feedback lengthening reaction that protects muscles against tearing.

(aw'tō-jen'ik in'hi-bish'ŭn)
A protective mechanism of the Golgi tendon organ, whereby a sudden stretch in a muscle causes a reflexive activation of the antagonist muscle and relaxation of the agonist.

The possible reduced strength after stretching at different insistence times can be partially explained by an autogenic inhibition generated by the stretching owed the activation of Golgi tendon organs (CHALMERS, 2004) which may cause a decrease in the excitability of [alpha]-motoneurons (FOWLES et al., 2000).
The justifications of autogenic inhibition and reciprocal inhibition are well accepted to justify such efficiency (CHALMERS, 2004).
Isometric contractions (the hold phase) and concentric contractions (the contract phase) used immediately before the passive stretch (the relax phase) facilitate autogenic inhibition. Autogenic inhibition is a reflex relaxation that occurs in the same muscle where the golgi tendon organ is stimulated.
They produce the autogenic inhibition reflex, and conscious perception of sense of effort.

The GTO and its reflex circuit (autogenic inhibition) prevent its muscle from contracting by "turning it off"; and 4.
The GTO and its reflex (autogenic inhibition) reduce, but do not shut off, the excitability of the motor neuron and its innervated muscle.
Autogenic inhibition means "self-generated inhibition." It is the name given to the spinal reflex response that occurs when the Golgi tendon organ receptor is activated, then producing an inhibitory response in the motor neurons that return to the same muscle and its synergists.
What is the function of the GTO's autogenic inhibition reflex?
Similarly, there is no evidence that GTO autogenic inhibition lasts longer than the contraction of its parent muscle.
* Autogenic inhibition produced by GTOs does not completely turn off contraction in the receptor's host muscle.
* GTOs produce autogenic inhibition of their host muscle and reciprocal excitation of antagonists.
