General description of the three glycemic groups. Data presented as median with 25 and 75 quartiles. The control group consisted of 78 subjects, the impaired glucose tolerance (IGT) of 58 subjects except for VO2max ( ), whole body fat % ( ), and whole body fat-free mass ( ), and the patients with type 2 diabetes (T2DM) of 64 except for hip ( ), waist ( ), whole body fat % ( ), and whole body fat-free mass ( ). HOMA2 S: homeostasis model assessment of insulin sensitivity. HOMA B: homeostasis model assessment of beta-cell function. BMI: body mass index. significantly different from the control group. , ,  and . Corrected for multiple testing using bonferroni. Chi square test.
