The effects of resistance training on hemoglobin A1c, body mass index, and muscle strength in patients with diabetes mellitus based on age (middle-aged and older adults): a systematic review and meta-analysis.

ABSTRACT:

Background

This study aimed to examine the effectiveness of resistance training on hemoglobin A1c (HbA1c) levels and body mass index in patients with diabetes mellitus, categorized by age.

Methods

A comprehensive search of English-language literature published between 1997 and 2025 was performed across 6 databases (Embase, CINAHL, Medline, Cochrane, PubMed, and PEDro). Standardized mean differences and 95% confidence intervals were calculated, and publication bias was assessed using funnel plots and Egger's test. The Joanna Briggs Institute checklist was applied to evaluate study quality.
