Resistance training reduces HbA1c levels in patients with T2D

Key clinical point: Resistance training (RT) effectively reduces glycosylated hemoglobin (HbA1c) in patients with type 2 diabetes mellitus (T2D), with RT interventions triggering a larger vs. medium or smaller improvement in muscular strength leading to a greater reduction in HbA1c.

Major finding: RT intervention vs. control treatment significantly decreased HbA1c (weighted mean difference −0.39; P < .001), with a larger vs. medium or small effect on muscular strength leading to a greater reduction in HbA1c (β −0.99; P = .0470).

Study details: Findings are from a meta-analysis of 20 trials including 1172 patients with T2DM.
