The golgi tendon organs are over-excited and the muscle spindles are inhibited
|
|
|
Both the muscle spindles and golgi tendon organs are over-excited
|
|
|
Both the muscle spindles and golgi tendon organs are inhibited
|
Detailed explanation-1: -When the Golgi tendon organ is excited for a prolonged period of time (at least 30 seconds according to National Academy of Sports Medicine), it provides an inhibitory effect to muscle spindles, which are trying to contract the muscle.
Detailed explanation-2: -If there is too much muscle tension the golgi tendon organ will inhibit the muscle from creating any force (via a reflex arc), thus protecting the you from injuring itself. This works in concert with the muscle spindles that monitor muscle length.
Detailed explanation-3: -Two important proprioceptors that play a role in flexibility, the GTO and muscle spindle work together reflexively to regulate muscle stiffness. When a GTO is stimulated, it causes its associated muscle to relax by interrupting its contraction.
