Caloric restriction (CR) and exercise are cornerstones in the treatment of obesity and cardiometabolic disorders. Recently, whole body electromyostimulation (WB-EMS) has emerged as a more time-efficient alternative to traditional resistance training (RT). However, the effects of WB-EMS compared to RT on cardiometabolic health in obese metabolic syndrome (MetS) patients performed during CR are still unclear. In total, 118 obese MetS patients (52.7 ± 11.8 years, BMI: 38.1 ± 6.9 kg/m) undergoing CR over 12 weeks (aim: -500 kcal deficit/day) were randomly allocated to either WB-EMS, single-set RT (1-RT), 3-set RT (3-RT) or an inactive control group (CON). Primary outcome was MetS severity (MetS z-score). Secondary outcomes were body composition, muscle strength and quality of life (QoL). All groups significantly reduced body weight (3%) and fat mass (2.6 kg) but only 1-RT and 3-RT preserved skeletal muscle mass (SMM). All exercise groups increased muscle strength in major muscle groups (20-103%). However, only the two RT-groups improved MetS z-score (1-RT: -1.34, = 0.003; 3-RT: -2.06, < 0.001) and QoL (1-RT: +6%, = 0.027; 3-RT: +12%, < 0.001), while WB-EMS and CON had no impact on these outcomes. We conclude that traditional RT has superior effects on cardiometabolic health, SMM and QoL in obese MetS patients undergoing CR than WB-EMS.
热量限制（CR）和运动是治疗肥胖和心脏代谢紊乱的基石。最近，全身电肌肉刺激（WB-EMS）作为传统抗阻训练（RT）的更高效替代方法出现了。然而，在进行 CR 期间，WB-EMS 与 RT 对肥胖代谢综合征（MetS）患者心脏代谢健康的影响仍不清楚。共有 118 名肥胖 MetS 患者（52.7±11.8 岁，BMI：38.1±6.9kg/m²）接受了为期 12 周的 CR（目标：每天减少 500 千卡热量），随机分配到 WB-EMS、单组 RT（1-RT）、3 组 RT（3-RT）或非活动对照组（CON）。主要结局是 MetS 严重程度（MetS z 评分）。次要结局是身体成分、肌肉力量和生活质量（QoL）。所有组的体重（3%）和脂肪量（2.6kg）都显著减少，但只有 1-RT 和 3-RT 保留了骨骼肌质量（SMM）。所有运动组的主要肌肉群的肌肉力量都增加了（20-103%）。然而，只有 2 个 RT 组改善了 MetS z 评分（1-RT：-1.34，=0.003；3-RT：-2.06，<0.001）和 QoL（1-RT：+6%，=0.027；3-RT：+12%，<0.001），而 WB-EMS 和 CON 对这些结果没有影响。我们得出结论，在进行 CR 的肥胖 MetS 患者中，传统 RT 对心脏代谢健康、SMM 和 QoL 的影响优于 WB-EMS。
