Exercise is a key nonpharmacological strategy for the management of sarcopenic obesity (SO), characterized by low muscle mass and excess fat. However, long-term interventions and specific modalities, such as power training (PT), remain unexplored in this population. : In this 32-week randomized controlled trial, 40 community-dwelling women (mean age: 77.0 ± 6.8 years) with sarcopenic obesity (per the EWGSOP2 and ESPEN criteria) were assigned to power training (PT), multicomponent training (MT), or a non-exercise control group (CG). Body composition, strength, and function were assessed pre- and post-intervention using within- and between-group analyses with effect size estimation. Nutritional intake was evaluated at baseline. : Significant pre-post intervention between-group differences were observed in appendicular skeletal muscle mass index (ASMI; = 0.039), body fat percentage (BF%; = 0.002), visceral fat (VF; = 0.044), appendicular muscle mass (ASM; = 0.021), gait speed (GS; = 0.018), timed up and go test (TUG; = 0.005), five-times sit-to-stand test (5STS; < 0.001), and Short Physical Performance Battery (SPPB; = 0.002). Large effect sizes (Cohen's d > 0.8) were found in the PT group for all these variables. Post hoc analyses indicated that PT was significantly superior to MT in improving 5STS ( = 0.005) and TUG ( = 0.025). Notably, 35.7% of the PT participants no longer met diagnostic criteria for SO after the intervention. : PT was more effective than MT and the CG in improving muscle mass, reducing fat, and enhancing functional performance in older women with SO. These findings support PT as a feasible and promising intervention.
运动是管理肌肉减少性肥胖（SO）的关键非药物策略，其特征是肌肉量低和脂肪过多。然而，长期干预措施以及特定模式，如力量训练（PT），在该人群中仍未得到探索。在这项为期32周的随机对照试验中，40名患有肌肉减少性肥胖（根据EWGSOP2和ESPEN标准）的社区居住女性（平均年龄：77.0±6.8岁）被分配到力量训练（PT）组、多组分训练（MT）组或非运动对照组（CG）。在干预前后，使用组内和组间分析以及效应量估计来评估身体成分、力量和功能。在基线时评估营养摄入情况。在干预前后，组间在四肢骨骼肌质量指数（ASMI；P = 0.039）、体脂百分比（BF%；P = 0.002）、内脏脂肪（VF；P = 0.044）、四肢肌肉质量（ASM；P = 0.021）、步速（GS；P = 0.018）、计时起立行走测试（TUG；P = 0.005）、五次坐立测试（5STS；P < 0.001）和简短体能测试电池（SPPB；P = 0.002）方面观察到显著差异。在PT组中，所有这些变量均发现有较大的效应量（科恩d>0.8）。事后分析表明，在改善5STS（P = 0.005）和TUG（P = 0.025）方面，PT显著优于MT。值得注意的是，35.7%的PT参与者在干预后不再符合SO的诊断标准。在改善患有SO的老年女性的肌肉量、减少脂肪和提高功能表现方面，PT比MT和CG更有效。这些发现支持PT作为一种可行且有前景的干预措施。
