AbstractExposure to whole-body vibration (WBV) has been related to stress, cognitive fatigue and a number of adverse health effects. However, the mechanisms for these effects are not clearly understood. Indeed "health effects" identified in the WBV standards (e.g. ISO- 2631) are weighted by frequency according to sensory magnitude rather than any measured physiological effects. NRC carried out a series of flights in which we manipulated the vibration profile of a Bell 412 helicopter was varied by altering the tuning of the main rotor, and observed differences in Heart Rate and Heart Rate Variability (HRV). We also manipulated the impedance properties of the seat cushion, and observed comparable relationships between vibration and HRV. HRV may prove to be a useful means of indexing the physiological effects of WBV exposure.
