During the WBV exposure, subjects adopted 5unsupported trunk flexion/extension positions (15, 10, 0, -10 and -15, ±2.5degrees from vertical), and 4 hip flexion positions (-10, 0, 10, and 20 degreesfrom the horizontal). WBV measurements were taken with a tri-axialaccelerometer at the buttock/seat interface and the head. Hydrostatic weighingwas also conducted to determine the subject’s adipose content. Adipose contentof the individual had no significant relationship with the seat-to-headtransmission of vibration. Vibration exposures at 4Hz had significantly moretransmission than vibration exposures at 6.3Hz. Vibration exposures in the Z-axis (vertical) had significantly more vibration transmission than vibrationexposures in the X- (front-to-back) and Y-axes (left-to-right). A significantinteraction was also found between trunk position, frequency and axis ofexposure.
