Immediate effects of whole-body vibration exposure on perceived exertion and peripheral hemodynamics in overweight and obese individuals

ABSTRACT

Objective

The study aim was to investigate the immediate effects of whole-body vibration (WBV) exposure in combination with physical exercises on perceived exertion and peripheral hemodynamic responses in overweight and obese individuals.

Methods

Thirty-six individuals who were overweight or obese (44% males, mean age = 44.17 (9.43) years, mean BMI = 33.29 (3.19) kg/m²) were recruited. Participants were randomly allocated to two groups: control (n = 17) and the WBV (n = 19) group with vibration at 30 Hz and amplitude of 2 mm for a 20-min single vibration session. All participants completed static and dynamic exercises on the sinusoidal-vertical vibration plate but without vibration exposure in the control group. The Borg Rating of Perceived Exertion Scale (RPE) was used to evaluate perceived exertion. Hemodynamic responses were measured with heart rate (HR), arterial blood pressure (aBP) and peripheral capillary oxygen saturation (SpO²) in the pre-WBV, post-WBV, and the recovery period.

Results

A prolonged increase in perceived exertion was observed in the WBV group (ES = 0.48, p = 0.025), as compared to the control group (ES = 0.10, p = 0.668) in the recovery period. However, the Borg RPE between-groups comparison showed no significant differences in the pre-WBV, post-WBV, and recovery periods. No significant differences in group-time interaction were found for HR, aBP, and SpO2 hemodynamics.

Conclusions

WBV exposure had no significant positive effect on perceived exertion and hemodynamic responses in overweight and obese individuals.
