Abstract

The aim of this single-arm pilot study was to determine the effects of whole-body vibration training (WBVT) on endothelial function in elderly patients with cardiovascular diseases, as well as its safety. A total of 20 elderly patients with stable cardiovascular diseases underwent WBVT, which consisted of five static resistance training exercises (squats, wide stance squats, toe-stands, squats + band, and front lunges). The parameters of WBVT included vertical vibrations, 30 Hz frequency, and a 3-mm peak-to-peak amplitude. Each vibration session lasted 30 seconds, with 120 seconds of rest between sessions. Before and after WBVT, the reactive hyperemia peripheral arterial tonometry index (RH-PAT index) and transcutaneous oxygen pressure (tcPO2) were recorded as a measure of endothelial function and peripheral blood circulation. Systolic blood pressure, diastolic blood pressure, heart rate, and arterial oxygen saturation of pulse oximetry (SpO2) were measured at each rest interval as well as before and after WBVT. All patients completed our WBVT protocol without adverse events. The RH-PAT index significantly increased following WBVT (1.42 to 2.06, P < 0.001). There were no significant changes in heart rate (P = 0.777), systolic blood pressure (P = 0.183), diastolic blood pressure (P = 0.925), or SpO2 (P = 0.248) during WBVT. In conclusion, we demonstrated the acute effects of WBVT on endothelial function, with no reports of adverse events. These findings support the need for further randomized controlled studies to investigate the long-term effects of WBVT.
