Autogenic_and_Reciprocal_Inhibition

What is Autogenic and Reciprocal Inhibition? Autogenic and reciprocal inhibition both occur when certain muscles are inhibited from contracting due to the activation of the Golgi tendon organ (GTO) and the muscle spindles. These two musculotendinous proprioceptors located in and around the joints and muscles respond to changes in muscle tension and length, which helps manage muscular control and coordination. The GTO, located between the muscle belly and its tendon, senses increased tension when the muscle contracts or stretches. When the muscle contracts, the GTO is activated and responds by inhibiting this contraction (reflex inhibition) and contracting the opposing (antagonist) muscle group. This process is known as autogenic inhibition. The GTO response plays an important role in flexibility. When the GTO inhibits the (agonist) muscle’s contraction and allows the antagonist muscle to contract more readily, the muscle can be stretched further and easier. Autogenic inhibition is often seen during static stretching, such as during a low-force, long-duration stretch. After 7 to 10 seconds, muscle tension increases and activates the GTO response, causing the muscle spindle in the stretched muscle to be inhibited temporarily, which makes it possible to stretch the muscle further. The muscle spindle is located within the muscle belly and stretches along with the muscle itself. When this occurs, the muscle spindle is activated and causes a reflexive contraction in the agonist muscle (known as the stretch reflex) and relaxation in the antagonist muscle. This process is known as reciprocal inhibition.
