The weight loss induced by bariatric surgery is accompanied by an important reduction in lean mass, where the aerobic capacity reflected by the peak oxygen consumption (V̇Opeak) may not improve in patients who remain sedentary after bariatric surgery. Whole-body electromyostimulation (WB-EMS) associated with physical exercise can improve aerobic capacity, body composition, and anxiety level after surgery. The aim of this study was to analyze whether a dynamic exercise training program (DET) plus WB-EMS after bariatric surgery improves aerobic capacity, body composition, sleep quality, and anxiety level.
Randomized, double-blind, sham-controlled study. Thirty-four patients were randomized after bariatric surgery into the WB-EMS (n = 17) or Sham (n = 17) groups. Body composition, anthropometry, sleep quality, anxiety level, and cardiopulmonary exercise testing (CPX) were performed before bariatric surgery and after DET which consisted of 30-min dynamic exercises applied five times a week, for a 6-week. WB-EMS sessions were interspersed for 3 days a week using currents for endurance (85 Hz, 350 ms), and two sessions for strength (30 Hz, 350 ms) during DET.
Only the WB-EMS group significantly increased time (p = 0.002) and distance (p = 0.004) during CPX, in addition to the improvement in systolic blood pressure (p = < 0.001), diastolic blood pressure (p = < 0.001) and leg fatigue (p = < 0.04) following recovery from exercise, when compared to Sham after intervention. Furthermore, both groups improved V̇Opeak (p = 0.03), and decreased total fat mass (p = < 0.001), sleep quality (p = 0.007), and anxiety level (p = 0.004) after the intervention.
DET associated with WB-EMS improved exercise performance, the cardiovascular response, and leg fatigue. Moreover, early intervention composed of dynamic exercises was able to improve anxiety and sleep quality as well as aerobic capacity.

减肥手术后体重减轻伴随着瘦体重的显著减少，减肥手术后久坐不动的患者其峰值耗氧量（V̇Opeak）所反映的有氧能力可能无法改善。全身肌电刺激（WB-EMS）与体育锻炼相结合可改善术后的有氧能力、身体成分和焦虑水平。本研究的目的是分析减肥手术后动态运动训练计划（DET）加WB-EMS是否能改善有氧能力、身体成分、睡眠质量和焦虑水平。
随机、双盲、假对照研究。34例减肥手术后患者被随机分为WB-EMS组（n = 17）和假手术组（n = 17）。在减肥手术前以及在每周进行5次、每次30分钟的动态运动、为期6周的DET后，进行身体成分、人体测量、睡眠质量、焦虑水平和心肺运动测试（CPX）。在DET期间，WB-EMS训练每周穿插3天，采用耐力电流（85Hz，350ms），并进行两次力量训练（30Hz，350ms）。
与干预后的假手术组相比，只有WB-EMS组在CPX期间的时间（p = 0.002）和距离（p = 0.004）显著增加，此外运动恢复后的收缩压（p = <0.001）、舒张压（p = <0.001）和腿部疲劳（p = <0.0４）也有所改善。此外，两组干预后V̇Opeak均有所改善（p = 0.03），总脂肪量（p = <0.001）、睡眠质量（p = 0.007）和焦虑水平（p = 0.004）均有所下降。
DET联合WB-EMS可改善运动表现、心血管反应和腿部疲劳。此外，由动态运动组成的早期干预能够改善焦虑和睡眠质量以及有氧能力。
