Скачать или смотреть Tight Hip Flexors Don't Lie — Minimalist Shoes Are Low Sensory

Minimalist shoes, despite popular belief, are LOW sensory. There is a big difference between what you feel directly under your feet and what your brain is actually sensing during forward movement. In this follow-up to my most recent video...

.... I explain why this lack of sensory input prevents your hip flexors from turning off. It's actually quite simple.

Walking is accomplished through a central pattern generator that requires sensory feedback to stay normalized. From the foot, that sensory feedback has to be a progression of "heel — arch — big toe". The problem with minimalist shoes is that, while on flat surfaces, the lateral surface of the heel, where the sural nerve is located, does not get stimulated, so no heel strike is sensed. For this reason, hip flexors do not turn off, because the signal to turn off is provided by stimulation on the lateral heel. The sural nerve is only a sensory nerve. It does not control muscles. But it must be sensed for proper muscular organization to occur while upright.
When walking on real earth, the sural nerve is stimulated because the unevenness of the ground hits the foot in all different directions. So, in reality, the biggest problem is flat surfaces.
If you wear minimalist shoes and spend most of your time on flat surfaces, especially combined with sitting and staring at screens for long periods of time, all the sensory information your brain uses to figure out where you are is lost. As it feels threatened, hip flexors will become overactive and stay overactive until you make changes.
