Abstract

Whole-Body Periodic Acceleration (WBPA) has been reported to induce endothelial nitric oxide and cause vasodilation. However, the effects of WBPA on blood pressure and cardiovascular hemodynamics are still unclear and controversial. The objective of this study was to determine whether a single session of 160-degree V-shape Whole-Body Periodic Acceleration (WBPA-V-160), i.e., periodic motion of the supine body headward to footward, improved blood pressure and cardiovascular parameters. A pre-evaluation and post-evaluation of blood pressure and cardiovascular hemodynamics via DynaPulse Noninvasive and Quantitative Hemodynamic Profile Analysis were performed after a single 30 min trial of WBPA-V-160 with a moving distance, headward to footward, of 2 mm, at a constant frequency of 4 Hz. Systolic BP, diastolic BP, heart rate, end systolic pressure, end diastolic pressure, mean arterial BP, and pulse pressure at post-evaluation were significantly lower than at pre-evaluation after WBPA-V-160, whereas systemic vascular compliance and brachial artery distensibility at post-evaluation were significantly higher than at pre-evaluation. The WBPA-V-160, performed for 30 min, did improve blood pressure and cardiovascular hemodynamics by lowing the BP parameters and enhancing systemic vascular compliance.
