To examine the effects of combined exercise (aerobic exercise and resistance training) on the management of type 2 diabetes. Articles published in English and Chinese based on a search of Medline, Excerpta Medica Database (Embase) and China National Knowledge Infrastructure (CNKI) databases were the source for this meta-analysis. A significant difference in maximal oxygen consumption (VO2max) was demonstrated between the combined exercise and non-exercise groups (Weighted mean difference WMD 2.66 ml/(kg/min), 95% CI 1.80 to 3.51, p < 0.05). Combined exercise reduced the HbA1c concentration (WMD -0.40%, 95% CI -0.54 to -0.26, p < 0.05), BMI (WMD -1.09 kg/m2, 95% CI -1.70 to -0.49, p < 0.05), decreased the waist circumstance (WMD -3.48 cm, 95% CI -5.28 to -1.6, p < 0.05), reduced the amount of abdominal subcutaneous fat (WMD -104.14 cm2, 95% CI -136.02 to -72.27, p < 0.05), and reduced the amount of abdominal visceral fat (WMD -32.26 cm2, 95% CI -56.87 to -7.66, p < 0.05). In addition, combined exercise reduced the SBP (WMD -5.47 mmHg, 95% CI -7.74 to -3.20, p < 0.05), and DBP (WMD 2.75 mg/dl, 95% CI -4.10 to -1.41, p < 0.05) and TG (WMD -12.61 mg/dl, 95% CI -24.00 to -1.21, p < 0.05), and increased the HDL-C (2.91 mg/dl, 95% CI 1.22 to 4.61, p < 0.05). Combined exercise is recommended in the management of type 2 diabetes patients.
