4.1 Improved insulin sensitivity following a short-term whole body vibration intervention

Journal: Al Ameen Journal of Medical Science, 2017; 10(1): 3-9

Study Context: This UK study was a joint project taken on by Abertay University, Dundee, the School of Medicine at the University of Dundee and Southamptom Solent University. In the UK, only 43% of diabetic men and 32% of diabetic women achieve the recommended 30 minutes of exercise 5 days per week. It had been demonstrated that 15 minutes per week of high intensity exercise can also significantly improve insulin sensitivity, however the safety of this type of exercise for certain overweight diabetics was questioned. Researchers identified Whole Body Vibration Training (WBVT) as a time and intensity efficient workout.

Five healthy sedentary individuals undertook oral glucose tolerance testing prior to and after completion of a 6-week progressive WBVT program. These individuals showed a 9% reduction in plasma glucose area under the curve post training; the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) decreased by 21%; the Cedarholm index of insulin sensitivity was increased by 18%.

The conclusion of this study is that WBVT is associated with improved insulin sensitivity in could produce clinically relevant effects on fat metabolism in sedentary young people. Large scale studies are now necessary to assess the effectiveness of WBV in diabetic populations.

Comments: It would be fair to say that vibration training for diabetic individuals is promising but that more research is certainly needed before we can say anything definitively.
