Effect of Whole Body Vibration Training on Glycemic Control in Type II Diabetic Patients

The study protocol of WBV includes twelve weeks of whole-body vibration training provided to the Type 2 diabetic patients. It was recommended to all participants that they follow their regular diet and medication during the training. Two sets of six 1-minute vibration squats were designed with 20 seconds of rest, 3 times weekly for a duration 12 weeks (total workout time 36 minutes a week), using a vertical vibration machine. The six static positions consisted of (a) a deep squat position (knee angle 900) (b) an elevated squat position (knee angle 1250) (c) an elevated squat position (with elevated heels) (d) a slight knee flexion1 (hand straps with shoulder bending) (e) a slight knee flexion (hand straps with shoulder abduction) and (f) a slight knee flexion 3 (hand straps with elbow flexion). The training load steadily increased from the initial vibration of 30 Hz and the platform amplitude was raised from 2 mm at week 1 to 40 Hz and from 4 mm at week 5 to the completion of training.

The control group was advised to their normal physical activity level, diet, and medication.
