Vibration transmissibility via the feet in individuals exposed to vibration while standing was measured, and whether transmissibility and subjective reports of discomfort is differed between males and females, was determined. Vibration transmissibility through the foot was measured while participants stood on a vibration platform. Vibration data were collected in accordance with the ISO 263 1-1 standard for whole body vibration. Frequency-weighted acceleration in the z-axis entering the foot was compared to frequency-weighted acceleration in the z-axis at the ankle. Measured z-axis vibration was lower at the ankle in all trials with the exception of one male. It can thus be hypothesized that anatomical structures of the foot, for example the heel fat pad, could play a role in attenuation of foot-transmitted vibration from the floor through the foot to the ankle. Vibration transmissibility to the ankle was significantly lower for females than males.
