For flexibility training it’s actually quite good. And as Bushido mentioned, it can improve myogenic tone and stability especially in th elderly.
But other than that its just a gimmick that sounded good on paper but that can actually be detrimental by screwing up motor patterns.
I didn’t think about the motor pattern issue.
Also, I would love to hear some flexibility protocols if that’s not too much trouble.
It`s not so much about the protocols as about the effect of the vibration themselves. Super fast vibrations will inhibit and even desensitize the muscle spindles thus you will be able to reach a greater range of motion simply because the stretch reflex will be partially inhibited.
although this will indeed help you improve flexibility, when performed over the long run you risk effectively inhibiting the muscle spindles for good (increasing their activation threshold if you want). This can cause two problems:
It will decrease strength (the stretch reflex contributes heavily to force production, especially in stretched position) and power (especially power, and speed).
It increases the risk of injury: the stretch reflex come into play to avoid an excessive lengthening of the muscle tissue. If it becomes too inhibited, the protection against excessive lengthening decreases and the risk for muscle tears increases.
So yes it’s effective to improve flexibility; but it should only be used for short blocks of training.
