Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Design: Randomized controlled trial. Subjects: The frail older persons meeting the Fried Frailty Criteria.
Interventions: All eligible subjects were randomly assigned to 4 groups:
(1) WBV group: Subjects received a whole-body vibration exercise alone; (2) Progressive resistance training (PRT) group: Subjects received progressive resistance training; (3) WBV+ PRT group: Subjects received the whole-body vibration and progressive resistance training; (4) Control group: Subjects received no intervention/training. The periods of intervention are 12 weeks.
Main measures: The lower extremities blood flow (the diameters and red blood cell velocity of the common femoral artery), timed up and go test, 30-second chair stand test, five times sit to stand test, lower extremities muscle strength, balance function, balance confidence, bone density, and general health status was assessed at the beginning of the study, at instant, 12 weeks and 24 month after the intervention.
Study hypothesis: Whole-body vibration exercise is a safe and effective method that can improve the lower extremity blood flow, mobility function, balance, muscle strength, bone density, and general health status in the frail elderly.

WBV training
Whole-body vibration training was performed on a commercial Galileo machine (Germany). Participants were required to stand on the moveable rectangular platform and positioned their feet at an equal and standardized distance from the axis of rotation so that the vertical vibration amplitude was 1-3 mm. The frequency was set at 6-26 Hz. The vibration protocol consisted of four to five bouts (60 seconds for each bout), and three to five times a week for 12 weeks. The positions taken by the subjects differed according to their function. Participants who could stand independently were instructed to adopt a "partial squat" position with slight flexion at the hips, knees, and ankle joints to damp the vibrations approximately at the pelvic level.
