Abstract
Objective To evaluate the effects of resistance training on cardiometabolic health-related outcomes in patients with type 2 diabetes mellitus (T2DM) and overweight/obesity.
Design Systematic review and meta-analysis of randomised controlled trials (RCTs).
Data sources PubMed, Web of Science, Scopus, Science Direct, Cochrane Library and Google Scholar databases were searched from inception up to May 2024. The search strategy included the following keywords: diabetes, resistance exercise and strength training.
Eligibility criteria for selecting studies RCTs published in English comparing resistance training alone with non-exercising standard treatment. Participants were adults diagnosed with T2DM and concurrent overweight/obesity (body mass index (BMI) ≥25 kg/m2).
Results A total of 18 RCTs qualified involving 1180 patients (48.6/51.4 female/male ratio; 63.3±7.0 years; 29.3±4.3 kg/m2). Waist circumference (standardised mean differences (SMD) −0.85 cm, 95% CI −1.66 to −0.04), waist-to-hip ratio (SMD −0.72, 95% CI −1.30 to −0.15), high-density lipoprotein cholesterol (SMD +0.40 mg/dL, 95% CI 0.07 to −0.72), triglycerides (SMD −0.54 mg/dL, 95% CI −1.06 to −0.02), fasting blood glucose (SMD −0.65 mmol/L, 95% CI −1.19 to −0.12), fasting insulin (SMD −0.74 uIU/mL, 95% CI −1.12 to −0.36) and glycated haemoglobin (SMD −0.32%, 95% CI −0.63 to −0.01) improved compared with standard treatment. The risk of bias was low to unclear, and the quality of evidence was very low to moderate.
Conclusions Resistance training as a standalone exercise intervention in the management and treatment of T2DM with concurrent overweight/obesity is associated with many cardiometabolic benefits when compared with standard treatment without exercise.
