whole body vibration

WBV (Wikipedia)

Whole body vibration (WBV) is a generic term used when vibrations (mechanical oscillations) of any frequency are transferred to the human body. Humans are exposed to vibration through a contact surface that is in a mechanical vibrating state. Humans are generally exposed to many different forms of vibration in their daily lives. This could be a driver's seat, a moving train platform, through a power tool, a training platform, or one of countless other devices. It is a potential form of occupational hazard, particularly after years of exposure.

When high frequency vibrations (above 50 Hz) enter through the hands, occupational safety concerns may arise. For example, working with a jackhammer has been known to develop vibration white finger. Exposures and limits have been estimated in the ISO 5349-1 for hand-transmitted vibration.

Whole body vibration training as a form of physical exercise can offer some fitness and health benefits, but it is not clear if it is as beneficial as regular physical exercise. A 2018 meta-analysis has shown that whole body vibration can improve bone mineral density in the lumbar spine of postmenopausal women as well as the femoral neck of postmenopausal women younger than 65.
