Effect of combined training versus aerobic training alone on glucose control and risk factors for complications in type 2 diabetic patients: a meta-analysis

To investigate the effectiveness of combined aerobic and resistance training (CT), we conducted this meta-analysis to directly compare the effect of CT with that of aerobic training (AT) alone on type 2 diabetic patients. We searched PUBMED, EMBASE, Cochrane Controlled Trials Register, and SPORT DISCUS (from the earliest date available to June 2013) for randomized controlled trials (RCTs) examining effects of CT versus AT in type 2 diabetic patients. Two reviewers selected studies independently. Seven studies met the study criteria (192 male patients, 240 female patients). We found that compared with AT, CT decreased HbA1c, abdominal adipose tissue, total cholesterol, and triglycerides. CT had similar effect on HDL cholesterol, LDL cholesterol, and blood pressure to AT alone. Study withdrawals were similar for AT and CT. No serious adverse events were reported. CT is more effective than AT and does not compromise study completion or safety when compared to AT.
