Abstract

Background: This randomized controlled trial examined the feasibility of adding eccentric exercise to a conventional cardiac rehabilitation program (CCRP) for coronary heart disease patients.

Methods: Ninety-three patients were randomly assigned to either the MIX group (eccentric ergometer + CCRP) or the CON group (concentric ergometer + CCRP) for 7 weeks. Training effectiveness was assessed based on "good responders" showing improved functional capacities, such as 6-minute walk test (6MWT) distance and maximal voluntary contraction of the plantar flexors (ankle MVC). Safety was monitored with a visual analog scale for muscle soreness, perceived exertion, and heart rate during training.

Results: The proportion of good responders was similar between groups (26% in MIX, 29% in CON, P=0.744). Both groups improved in 6MWT (CON: 12.6%, MIX: 16.14%) and ankle MVC (CON: 15.5%, MIX: 11.30%), with no significant differences. Exercise tolerance did not differ significantly between the groups, but perceived effort was significantly lower in the MIX group (P<0.0001) compared to the CON group.

Conclusions: Integrating eccentric exercise into cardiac rehabilitation is safe and well-tolerated. Nevertheless, this study did not find significant advantages over conventional programs for coronary heart disease patients. Further research should explore specific patient groups or conditions where eccentric exercise may be more beneficial, emphasizing personalized prescriptions and gradual workload progression for better cardiac rehabilitation outcomes.

冠心病康复计划中偏心骑行的影响:一项实用随机对照试验与传统康复对比。
背景这项随机对照试验研究了在冠心病患者的常规心脏康复计划(CCRP)中加入偏心运动的可行性:93名患者被随机分配到MIX组(偏心测力计+CCRP)或CON组(同心测力计+CCRP),为期7周。训练效果根据 "良好反应者 "的功能改善情况进行评估,如 6 分钟步行测试 (6MWT) 距离和跖屈肌最大自主收缩 (踝关节 MVC)。在训练过程中,使用视觉模拟量表监测肌肉酸痛、感觉用力程度和心率,以确保安全:两组反应良好者的比例相似(MIX 组为 26%,CON 组为 29%,P=0.744)。两组在 6MWT (CON:12.6%,MIX:16.14%)和踝关节 MVC(CON:15.5%,MIX:11.30%)方面均有改善,无显著差异。两组的运动耐受力无明显差异,但 MIX 组的感知努力程度明显较低(结论:MIX 组的运动耐受力明显高于 MIX 组):将偏心运动纳入心脏康复是安全且耐受性良好的。尽管如此,这项研究并未发现冠心病患者参加偏心运动比参加传统项目有明显优势。进一步的研究应探讨偏心运动可能更有益的特定患者群体或病症,强调个性化处方和循序渐进的工作量,以获得更好的心脏康复效果。
