“…Reported studies show a transmission ratio greater than 2.0 at the ankle and below 0.6 at the knee, hip, sternum, and head (Bressel et al, 2010). This decrease in the acceleration values is reported as a consequence of the increase in the distance between the body segment and the vibration source (Avelar et al, 2013;Crewther et al, 2004;Harazin & Grzesik, 1998;Kiiski et al, 2008;Pollock et al, 2010).…”

“…Several studies conducted mostly in the industrial field show that vibration exposure can cause both acute and chronic injury to a range of physiological systems such as the musculoskeletal, circulatory, and nervous systems (Griffin, 1996). These injuries include back pain, cartilage damage, nerve damage (Govindaraju, Curry, Bain, & Riley, 2008), brain damage, blurred vision (Costa, Arezes, & Melo, 2014), hearing loss (Iki et al, 1987), or low back pain (Boshuizen, Bongers, & Hulshof, 1990;Dupuis & Zerlett, 1987). Not enough is known about the long-term effects of exposure to vibratory platforms.…”

“…The first corresponds to the parameters that are dependent on the participant such as anthropometry (Bressel et al, 2010;Pel et al, 2009) and body position (Avelar et al, 2013;Crewther et al, 2004;Harazin & Grzesik, 1998;Muir et al, 2013;Pel et al, 2009;Tankisheva et al, 2013). The body positions tested in these studies are standing normal (Harazin & Grzesik, 1998;Muir et al, 2013;Tankisheva et al, 2013), legs stiffened (Crewther et al, 2004;Harazin & Grzesik, 1998), legs bent (Di Giminiani et al, 2013;Harazin & Grzesik, 1998;Tankisheva et al, 2013), and squat (Crewther et al, 2004;Di Giminiani et al, 2013;Harazin & Grzesik, 1998;Tankisheva et al, 2013).…”

“…To assess these effects, different studies measure the acceleration dose in 'g' units and the vibration's transmissibility at different parts of the human body (Avelar et al, 2013;Bressel, Smith, & Branscomb, 2010;Pel et al, 2009). The transmissibility is the ratio of the vibration value at the input to the vibration at another point of the system.…”

Whole body vibration (WBV) is used as a training method but its physical risk is not yet clear. Hence, the aim of this study is to assess the exposure to WBV by a measure of acceleration at the lower limb under dynamic and static postural conditions. The hypothesis of this paper is that this assessment is influenced by the frequency, position, and movement of the body. Fifteen healthy males are exposed to vertical sinusoidal vibration at different frequencies (20-60 Hz), while adopting three different static postures (knee extension angle: 180°, 120° and 90°) or performing a dynamic half-squat exercise. Accelerations at input source and at three joints of the lower limb (ankle, knee, and hip) are measured using skin-mounted accelerometers. Acceleration values (g) in static conditions show a decrease in the vibrational dose when it is measured at a more proximal location in the lower extremity. The results of the performed statistical test show statistically significant differences (p < 0.05) in the transmissibility values caused by the frequency, the position, and to the presence of the movement and its direction at the different conditions. The results confirm the initial hypothesis and justify the importance of a vibration assessment in dynamic conditions.

“…The result shows high muscle activities in right leg and abdomen due to increase in vibration frequency whereas in left leg, muscle activities were decreased. Bresselet al [4] studied to determine the whole body vibration in children other than adults while standing on vibrating platform and found that transmission of whole body vibration does not differ between adults and children. The only difference is that transmission of whole body vibration to hip and ankle is more in children as compared to adults.…”
