Obesity, particularly in conjunction with further cardiometabolic risk factors, is associated with an increased risk of cardiovascular disease and mortality. Increased physical activity and dietary modifications are cornerstones of therapeutic interventions to treat obesity and related risk factors. Whole-body electromyostimulation (WB-EMS) has emerged as an innovative, time-efficient type of exercise that can provide positive effects on body composition and muscle strength. However, the impact of WB-EMS on cardiometabolic health in obese individuals with metabolic syndrome (MetS) has yet to be determined. The aim of this pilot study was, therefore, to investigate the feasibility and effects of WB-EMS on cardiometabolic risk markers and muscle strength in obese women diagnosed with MetS. Twenty-nine obese women (56.0 ± 10.9 years, BMI: 36.7 ± 4.6 kg/m) with the clinical diagnosis of MetS were randomized to either 12 weeks of WB-EMS (n = 15) or an inactive control group (CON, n = 14). Both groups received nutritional counseling (aim: -500 kcal energy deficit/day). WB-EMS was performed 2x/week (20 min/session). Body composition, maximum strength (F) of major muscle groups, selected cardiometabolic risk indices and the metabolic syndrome Z-score (MetS-Z) were determined baseline and after the intervention. WB-EMS was well tolerated and no adverse events occurred. Body weight was significantly reduced in both groups by an average of ~3 kg (P < 0.01). The body fat percentage was only decreased in the WB-EMS group (P = 0.018). Total cholesterol concentrations decreased in the WB-EMS group (P = 0.018) and in CON (P = 0.027). Only the WB-EMS group increased F significantly in all major muscle groups (P < 0.05) and improved the overall cardiometabolic risk score (MetS-Z, P = 0.029). This pilot study indicates that WB-EMS can be considered as a feasible and time-efficient exercise option for improving body composition, muscle strength and cardiometabolic health in obese women with MetS. Moreover, these findings underpin the crucial role of exercise during weight loss interventions in improving health outcomes.
肥胖症，特别是与其他心血管代谢危险因素并存时，会增加心血管疾病和死亡的风险。增加身体活动和饮食改变是治疗肥胖症和相关危险因素的治疗干预的基石。全身肌电刺激（WB-EMS）已成为一种创新的、高效的运动方式，可以对身体成分和肌肉力量产生积极影响。然而，WB-EMS 对代谢综合征（MetS）肥胖患者的心血管代谢健康的影响尚未确定。因此，本研究旨在探讨 WB-EMS 对肥胖女性 MetS 患者的心血管代谢风险标志物和肌肉力量的可行性和效果。29 名肥胖女性（56.0±10.9 岁，BMI：36.7±4.6 kg/m）被临床诊断为 MetS，随机分为 12 周 WB-EMS 组（n=15）或非活动对照组（CON，n=14）。两组均接受营养咨询（目标：每天减少 500 千卡能量摄入）。WB-EMS 每周进行 2 次（每次 20 分钟）。在基线和干预后测定身体成分、主要肌肉群的最大力量（F）、选定的心血管代谢风险指数和代谢综合征 Z 评分（MetS-Z）。WB-EMS 耐受良好，无不良事件发生。两组体重均显著减轻，平均约 3 公斤（P<0.01）。只有 WB-EMS 组的体脂百分比降低（P=0.018）。总胆固醇浓度在 WB-EMS 组（P=0.018）和 CON 组（P=0.027）降低。只有 WB-EMS 组所有主要肌肉群的 F 均显著增加（P<0.05），整体心血管代谢风险评分（MetS-Z）改善（P=0.029）。本研究表明，WB-EMS 可作为肥胖女性 MetS 患者改善身体成分、肌肉力量和心血管代谢健康的可行且高效的运动选择。此外，这些发现支持了在减肥干预期间运动在改善健康结果方面的关键作用。
