AbstractThe purpose of this study was to examine the effect the body weight and position on the mechanical output of vibration platform measured as maximal acceleration of vertical sinusoidal oscillations of vibrating plate. We examined five subjects applying the frequencies 20, 25, 30, 35, 40 Hz and different amplifier’s voltage output fed to mechanical vibration generator. We found that at given frequency and voltage the greatest vibration of vibrating plate has been observed when subject stood on the forefoot; this effect was more distinctly pronounced at lower frequencies. The effect of body mass was less consistently evident. The effect of foot placement on the oscillations of vibration platform may be caused by different absorption of the mechanical energy by the body. We believe that in order to explain effect observed a mathematical model which accounts for body position on absorption of vibration along the trunk and mechanical properties of the platform should be constructed by combining already existing models of human body.
