The HbA1c, which is used as a predictor for the progression of diabetes, is a method of monitoring blood sugar imbalance as well as evaluating the risk of diabetic complications (Menz et al. 2004). This study revealed a significant decrease of 0.8% in the WBV group as compared to the other groups, which showed an increase of 0.2%. In a previous study wherein intervention exercises for diabetes were applied at an intensity of 40-50% for less than 8 weeks, no significant improvement in HbA1c was observed (Ishii et al. 1998).
