The Effect of Whole-body Vibration Training

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

Detailed Description
-----------------
The experimental group participated in 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
