Abstract Purpose: The present study aimed to investigate the effects of 12 weeks of resistance training an‎d whole-body electrical muscle stimulation (WB-EMS) on body composition, muscle strength, telomeric indices, including hTERT gene expression, an‎d physiological age in overweight men. Methods: This study was semi-experimental in design. Participants were divided into three groups: resistance training, WB-EMS, an‎d control. The dependent variables included total body water, skeletal muscle mass, soft lean mass, lean body mass, body fat percentage, body protein, body minerals, han‎dgrip strength, an‎d telomeric indices. Physiological age was calculated using a composite model consisting of body composition components, functional indices, an‎d telomere-related cellular markers. Results: The results showed that WB-EMS training led to a significant reduction in body fat percentage (p=0.007). In addition, a significant increase in han‎dgrip strength was observed in the WB-EMS group (p=0.011). An improvement in skeletal muscle mass was also observed in this group. In contrast, a significant reduction in estimated body minerals was reported in the WB-EMS group (p=0.019), which should be interpreted with caution due to the indirect nature of body composition assessment using bioelectrical impedance analysis (BIA). Conclusion: The findings of the present study indicate that WB-EMS training may be considered an effective an‎d multidimensional intervention for improving body composition, enhancing muscular function, an‎d modulating some indices related to physiological aging in overweight men. However, changes in body composition an‎d telomeric indices should be interpreted cautiously, considering the measurement method, sample size, an‎d statistical significance of the findings.
