摘要

研究表明,有氧能力越高,心血管死亡和发病的风险就越低。对于心脏病患者来说,高强度间歇训练(HIIT)似乎比中等强度持续训练(MICT)更能有效提高有氧能力。本研究的目的是调查两种基于社区的锻炼计划,采用两种短期方案(HIIT 和 MICT)对冠状动脉疾病(CAD)患者的体能和体力活动(PA)水平的影响。研究方法在这项随机对照试验中,对 69 名确诊为冠状动脉粥样硬化症(CAD)的患者进行了为期 6 周的干预前后的身体成分、有氧运动能力、肌肉力量和日常体力活动水平评估。所有患者被随机(1 : 1 : 1)分配到两个锻炼组(HIIT 或 MICT)或对照组(不锻炼)。两个训练计划都包括为期 6 周的有指导的跑步机运动,每周三次。MICT的目标是达到峰值心率(HR)的≈70-75%,而HIIT的目标是达到峰值心率(HR)的≈85-95%。对照组只遵循医学建议。结果显示与对照组相比,社区锻炼计划对体能变量和体育锻炼水平有更积极的影响。与MICT相比,HIIT能明显改善腰围、体脂量、VO2峰值、久坐行为和中度至剧烈运动。此外,对照组的效果较差。结论HIIT 比 MICT 和对照组更能改善健康状况。这些研究结果表明,HIIT 可能是社区运动计划中针对 CAD 患者的另一种有效训练方法。该试验已在 NCT03538119 上注册。

Improving Health Outcomes in Coronary Artery Disease Patients with Short-Term Protocols of High-Intensity Interval Training and Moderate-Intensity Continuous Training: A Community-Based Randomized Controlled Trial
Studies have shown that the higher the aerobic capacity, the lower the risk of cardiovascular mortality and morbidity. In the case of cardiac patients, high-intensity interval training (HIIT) seems to be more effective than moderate-intensity continuous training (MICT) in improving aerobic capacity. The aim of this study was to investigate the effects of two community-based exercise programs using two short-term protocols (HIIT and MICT) on physical fitness and physical activity (PA) levels in coronary artery disease (CAD) patients. Methods. In this randomized controlled trial, body composition, aerobic capacity, muscle strength, and daily PA levels were assessed before and after 6 weeks of intervention in 69 patients diagnosed with CAD. All patients were randomly (1 : 1 : 1) assigned to two exercise groups (HIIT or MICT) or a control group (no exercise). Both training programs consisted of 6 weeks of supervised treadmill exercise, three sessions per week. MICT targeted ≈70-75% of peak heart rate (HR), while HIIT aimed for ≈85-95% of peak HR. The control group only followed the medical recommendations. Results. Community-based exercise programs showed more positive effects on physical fitness variables and physical activity levels compared to control. HIIT could significantly improve waist circumference, body fat mass, VO2peak, sedentary behavior, and moderate-to-vigorous PA compared to MICT. Moreover, the control group showed poorer results. Conclusion. HIIT can improve health outcomes more positively than MICT and control. These findings indicate that HIIT may be an alternative and effective training method in community-based exercise programs for CAD patients. This trial is registered with NCT03538119.
