The optimal frequency in the whole-body vibration treatment

Vibration characteristics (i.e. vibratory application, amplitude, frequency, and exercise protocols) are the main factors influencing the neuromuscular and hormonal profile. Basically, the intensity of vibration load on the neuromuscular is determined by the vibration frequency and amplitude. In most studies, the frequency of the applied vibration ranges between 20 and 40 Hz, and the amplitude between 1 and 5 mm. In the aforementioned studies, however, the vibration training was applied without individualizing the vibration frequency to each participant. Using the EMG muscle response during vibration exposure as a neuromuscular index appears to be appropriate for identifying an individual’s optimum frequency of stimulation. Therefore, an individualized vibration frequency should be prescribed similarly to exercise prescription for progressive resistance exercise in terms of load, number of repetitions, and series.
