Each machine has a Gforce rating also along with vibration frequency vibration amplitude and weight capacity ratings As obvious Gforce is nothing but the measure of acceleration rate of change of velocity that the body experiences during the vibration session So the higher is the Gforce the higher will be the intensity of exercise .
Learn more2013320Fundamentals of Vibration Measurement and Analysis Explained Thanks to Peter Brown for this article Older style vibration meters were able to calculate RMS values using simple The diagram on the previous page showed a typical value for vibration of 12 g rms.
Learn moreAt this point it becomes important to distinguish between Vibration Training machines and Vibration Massage machines In the European Space Agency experiments the most successful outcomes came from using a Gforce of 15G 7 Reducing that to 10G resulted in partial success.
Learn moreVibration machines have the ability to multiply the gforce by varying the differential ratio or up and down motion of their machine To put it simply Gforce is a function of frequency hzHz is decided by the differential that the manufacturer uses In essence if you want a higher gforce you use a bigger differential ratio if you want a .
