Effect of whole-body vibration after a resistance exercise bout on heart rate variability in hypertensive population.

Abstract

To investigate the effect of whole-body vibration (WBV) in the recovery phase after resistance exercise (RE) bout on heart rate variability (HRV) and blood pressure (BP) in a hypertensive population. Twenty hypertensive males and females were randomly allocated into group A (RE bout), and group B (RE bout with WBV). Pre-test and post-test measure of HRV, systolic blood pressure, and diastolic blood pressure were taken before and after RE and placebo WBV in one group and in another group of RE with WBV in the recovery phase. There were no significant differences in both RE bout group and RE bout with WBV on HRV parameters but on BP it has shown significant improvement in both groups with a p value of SBP and DBP as 0.001 and 0.03 respectively but comparatively RE with WBV in recovery has greater improvement. Our data demonstrated that RE bout using WBV has no improvement on HRV but it has significantly improved BP in hypertensive population.
