What role do Golgi tendon organ receptors (muscle force) play in improving motor performance?

Golgi tendon organs connect to extrafusal fibres near the tendon’s junction to muscle. They detect tension generated by active muscle to protect the muscle and surrounding connective tissue from sudden or excessive load. When stimulated, Golgi receptors transmit signals to the spinal cord (via 1b afferents) to elicit reflex inhibition of the muscles they supply.
