The Effect of Whole-body Vibration Training

The Effect of Whole-body Vibration Training on Biomarkers and Health Beliefs of Prefrail Older Adults: A Quasi-experimental Research

The whole-body vibration programme employed in this study partly improved the biomarkers and health beliefs of the prefrail community-dwelling older adults.

Participant Group / Arm	Intervention / Treatment
Experimental: whole-body vibration training; a 12-week whole-body vibration training that conducted 3 times per week, with 5-min continuous vibration at 12-Hz frequency and 3-mm amplitude each time.	Device: whole-body vibration training; The experimental group participated in a 12-week whole-body vibration training that was conducted 3 times per week, with 5-min continuous vibration at 12-Hz frequency and 3-mm amplitude each time.
