220118 Lowered inhibition of the neural reflexes

Once the CNS receives the information, the necessary changes occur through the unconscious effort of the neuromuscular reflexes. An automatic feedback system allows the body to continually monitor the actions and positions of the muscle and limb behavior.

It is thought by some research scientists that a higher level of neural inhibition may exist in some athletes due to previous bad experiences with the exercise that lead to an injury.

Inhibition of the Golgi tendon organs and other self protecting devices in the neuromuscular system

Reduced muscle activation may be explained in some part by the actions within the muscle group such as the autogenic inhibition provided by the Golgi Tendon reflex (shuts the muscle down if it is perceived to be under a damaging load).

The Golgi tendon network protects the muscle fibers from being destroyed by excessive loading beyond their capacity to survive destruction. This process occurs as a result of receptors located within the tendons of the muscles, which are continuously monitoring the tension of the affected musculature. Furthermore this setup contributes to the coordination of the active muscles to make the movement highly synchronized.

Some authorities believe the Golgi tendon function is set far to low and that even a slight disinhibition would enable a dramatically superior physical response to an imposed load. Violent ballistic pre-movements may dis-inhibit the Golgi feedback patterns, but in doing so the athlete risks causing severe damage to the involved tissues. Other mechanisms within the structure also add input into the ability to develop strength.

The mechanoreceptor and nociceptor afferent inhibition (the signals from the muscle cells to the CNS), inhibition due to fatigue, pressure within the joint inhibition due to excessive range of motion movements during the stretching activity, and finally the myotonic (stretch-reflex) response from the muscle spindles which resist the lengthening of the muscle and cause a contraction to occur.

The neural inputs into strength development are far ranging and important to consider while training. Just as essential to this process is the involvement of the muscle and bone lever system to the production of strength and power in the athlete.
