Key result
Whole-body vibration after a resistance exercise bout did not improve heart rate variability but significantly improved systolic (P=0.001) and diastolic (P=0.03) blood pressure in hypertensive patients.
Why the study?
The study was conducted to investigate the effect of whole-body vibration in the recovery phase after a resistance exercise bout on heart rate variability and blood pressure in a hypertensive population.
Does whole-body vibration after a resistance exercise bout improve heart rate variability and blood pressure in a hypertensive population?

Does whole-body vibration after a resistance exercise bout improve heart rate variability and blood pressure in a hypertensive population?
Whole-body vibration during recovery from resistance exercise improves blood pressure but not heart rate variability in hypertensive patients.

Supports WBV post-resistance exercise for BP reduction in hypertension; extends recovery strategy evidence while leaving HRV effects unresolved.
OBJECTIVES: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: Our data demonstrated that RE bout using WBV has no improvement on HRV but it has significantly improved BP in hypertensive population.

Hanif et al. (2021) conducted an RCT in Hypertension (n=20). Whole-body vibration (WBV) in the recovery phase after resistance exercise (RE) vs. Resistance exercise (RE) with placebo WBV was evaluated on Heart rate variability and blood pressure (p=0.001 for SBP, 0.03 for DBP). Whole-body vibration after a resistance exercise bout did not improve heart rate variability but significantly improved systolic (P=0.001) and diastolic (P=0.03) blood pressure in hypertensive patients.
