Resistance Training in the Treatment of the Metabolic Syndrome: A Systematic Review and Meta-Analysis of the Effect of Resistance Training on Metabolic Clustering in Patients with Abnormal Glucose Metabolism.

Over the last decade, investigators have given increased attention to the effects of resistance training (RT) on several metabolic syndrome variables. The metabolic consequences of reduced muscle mass, as a result of normal aging or decreased physical activity, lead to a high prevalence of metabolic disorders. The purpose of this review is: (i) to perform a meta-analysis of randomized controlled trials (RCTs) regarding the effect of RT on obesity-related impaired glucose tolerance and type 2 diabetes mellitus; and (ii) to investigate the existence of a dose-response relationship between intensity, duration and frequency of RT and the metabolic clustering. In the 13 RCTs included in the analysis, RT reduced glycosylated haemoglobin (HbA1c) by 0.48%, fat mass by 2.33 kg and systolic blood pressure by 6.19 mmHg. There was no statistically significant effect of RT on total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglyceride and diastolic blood pressure.

Based on this meta-analysis, RT has a clinically and statistically significant effect on metabolic syndrome risk factors such as obesity, HbA1c levels and systolic blood pressure, and therefore should be recommended in the management of type 2 diabetes and metabolic disorders.
