Constant exposure to the stimulus causes an improvement in the response of the nervous system and new opportunities for organization with respect to external stimuli.… The presence of different programs that combine multiple frequencies, allows us to modulate the response of the nervous system according to what we want to achieve both from the point of view of post-training recovery, and from the point of view of optimization of activation processes muscle. The daily exposure to these frequencies causes changes in the coordinated activation state of the flexor and extensor muscles, a correct neuromuscular response, referable to the absence of a hypertonic condition, and a state of readiness of the autonomic nervous system, through a condition that tends to vagotonic.
