The Effects of Acute Bouts of Whole Body Vibration on Central Hemodynamics in Frail Older Adults: A Pilot Study

Abstract Introduction: This study investigates whether an acute bout of whole body vibration (WBV): (i) improves measures of central hemodynamics and (ii) can be completed without inducing orthostatic intolerance in frail older adults. Methods: Nine rest home residents participated in a cross-over design incorporating WBV and non-vibrational control conditions (CON) on 2 separate testing days. The order of the two testing conditions was randomized. Participants completed 10 sets of 60 seconds of WBV training or CON with an inter-set rest period of 60 seconds. Results: During training, no interaction or between-condition effects were observed for any variable. Following training, there was an interaction effect reported for augmentation index (AIx) (P < 0.019) and a significant large increase in AIx for WBV (P = 0.020, Eta = 0.202). Three participants exhibited one-off notable decreases in either central systolic or diastolic blood pressure. Conclusion: An acute bout of WBV is a safe training method for frail older adults.
