<jats:p><jats:bold>Objective:</jats:bold> To analyze the effects of whole body electrostimulation (WB-EMS) with body weight training on functional fitness and body composition of older men.</jats:p><jats:p><jats:bold>Methods:</jats:bold> Twenty physically inactive older men were randomized into: Control group (control), performed the body weight exercise training wearing electrostimulation clothing, but without receiving electrical current stimuli (<jats:italic>n</jats:italic> = 10), and body weight associated with whole body electrostimulation group (BW+WB-EMS), performed the body weight exercise training wearing electrostimulation clothing plus whole body electrostimulation (<jats:italic>n</jats:italic> = 10). The training sessions were performed twice a week for 6 weeks and included eight exercises using body weight, performed in two sets of eight repetitions. Physical function was assessed using a battery composed of seven tests, six derived from the Senior fitness test and a handgrip strength test. We also measured the muscle thickness (MT) of the biceps and triceps brachii and vastus lateralis.</jats:p><jats:p><jats:bold>Results:</jats:bold> The BW+WB-EMS group presented increased (<jats:italic>p</jats:italic> &lt; 0.05) performance in the 30-s chair stand test (10.2 ± 3.3 vs. 13.8 ± 5.0 reps), arm curl (16.6 ± 3.9 vs. 19.9 ± 6.1 reps), 6-min walk test (402 ± 96 vs. 500 ± 104 m), and handgrip strength test (30 ± 11 vs. 32 ± 11 kgf). The BW+WB-EMS group also presented increased MT (<jats:italic>p</jats:italic> &lt; 0.05) in the biceps brachii (17.7 ± 3.0 vs. 21.4 ± 3.4 mm), triceps brachial (14.7 ± 3.6 vs. 17.5 ± 4.1 mm), and vastus lateralis muscles (15.1 ± 2.6 vs. 18.6 ± 4.3 mm). Moderate correlations were found in arm curl (<jats:italic>p</jats:italic> = 0.011, <jats:italic>r</jats:italic> = 0.552) but not handgrip strength (<jats:italic>p</jats:italic> = 0.053, <jats:italic>r</jats:italic> = 0.439) with changes in the biceps MT. Moderate changes in the 6-min walk distance were significantly correlated with changes in vastus lateralis MT (<jats:italic>p</jats:italic> = 0.036, <jats:italic>r</jats:italic> = 0.471). There was a moderate correlation between the changes in the 30-s chair stand test (<jats:italic>p</jats:italic> = 0.006, <jats:italic>r</jats:italic> = 0.589) and changes in the vastus lateralis MT. Furthermore, although a moderate correlation (<jats:italic>r</jats:italic> = 0.438) was found between triceps MT and handgrip strength no significant difference (<jats:italic>p</jats:italic> = 0.053) was reported. Additionally, there were no statistical differences in any parameters for the control group.</jats:p><jats:p><jats:bold>Conclusion:</jats:bold> WB-EMS with body weight training increased functional fitness and MT in physically inactive older men.</jats:p>
