Background/Objectives Bariatric surgery (BS) is a successful, long-lasting treatment option for obese. The early postoperative (PO) period is followed by dietary restriction and physical inactivity, leading to declines in muscle mass and functional capacity. Whole-body electromyostimulation (WB-EMS) may be a feasible and potential early rehabilitation strategy post BS. The aim was to evaluate the effects of WB-EMS with exercise training (Fe) on functional capacity, body composition, blood biomarkers, muscle strength, and endurance post BS. Subjects/Methods This is a randomized, triple-blind, sham-controlled trial. Thirty-five volunteers underwent a Roux-en-Y gastric bypass and were randomized into a WB-EMS (WB-EMSG) or control group (ShamG). Preoperative evaluations consisted of maximal and submaximal exercise testing, body composition, blood biomarkers, quadriceps strength, and endurance. After discharge, functional capacity and body composition were obtained. Exercise training protocols in both groups consisted of 14 dynamic exercises, 5 days per week, completing 30 sessions. The WB-EMSG also underwent an electrical stimulation protocol (Endurance: 85 Hz, 350 ms, 6 s of strain, 4 f of rest; Strength: 30 Hz, 350 ms, 4 s of strain, 10 seconds of rest, with bipolar electrical pulse). After intervention, subjects were reevaluated. Results The protocol started on average 6.7 +/- 3.7 days after discharge. Both groups presented with a decline in functional capacity after BS (p < 0.05) and a reduction in all body composition measurements (p < 0.05). The exercise training program led to significant improvements in functional capacity (ShamG - PO: 453.8 +/- 66.1 m, Post: 519.2 +/- 62.8 m; WB-EMSG- PO: 435.9 +/- 74.5, Post: 562.5 +/- 66.4 m, p < 0.05), however, only the WB-EMSG demonstrated significant changes of distance walked (interaction time vs group effect, p < 0.05). In addition, adiponectin significantly increased only in the WB-EMSG (p < 0.05). The WB-EMSG was also able to preserve muscle strength, endurance, and fatigue index, while the ShamG demonstrated significant decline (p < 0.05). Conclusion WB-EMS + Fe can be an attractive and feasible method following BS to enhance functional capacity and prevent deterioration of muscle function in the early PO. (AU)
