….The Golgi stretch reflex is for skeletal muscle so I’m afraid it doesn’t have anything to do with stretching your penis, even though stretching slow is important. The stretch reflex is initiated by a stretch in the muscle spindle by movement voluntary or otherwise. A action potential travels by way of the Ia afferent neuron from the muscle spindle to the spinal column where it connects with inter-neurons which can act inhibitors sending a signal to the antagonist muscle group or/and send an impulse to efferent motor units which inervate the agnostic muscle and those muscles which perform the same motor action (abduction, elevation, depression, flexion, etc.) The more rapid the stretch the stronger the inhibition of antagonist muscles and activation of the agnostic muscle groups. This is the basis of reflex actions and plyometric training.
Yes, I’ve utilized plyometrics in the past, when I hit the gym with regularity.
However, I’m curious if you’re certain that the golgi reflex is limited to skeletal muscle. In my experimentation with stretching (with PE), I’m certain - beyond any doubt - that I get a much better stretch if I ease into very slowly.
The stretch feels much deeper and, in fact, my unit extends further (in stages) during such a stretch - as per BPFSL measuring. I’m not certain which other bodily mechanism might be responsible for this occurrence, but I’m sure that my experience is not merely a placebo effect.
This would appear to me to be the side-tracking of some type of injury-preventing inhibiting mechanism (“golgi” or not).
So, my exhortation to stretch slowly is not merely for the sake of safety, but for also getting a much deeper, more effective stretch.
