Cardiovascular diseases are among the most common and clinically significant comorbidities of chronic obstructive pulmonary disease (COPD). Exercise has been shown to reduce the risk of cardiovascular diseases, and high-intensity inspiratory muscle training (H-IMT) has emerged as a promising intervention for improving arterial stiffness in individuals with COPD. Yet, there is limited evidence from randomized controlled trials (RCTs) regarding the impact of H-IMT alone or in combination with exercise on reducing arterial stiffness in COPD. We designed a three-arm RCT to evaluate the effectiveness of H-IMT, both alone and in combination with exercise, in reducing brachial-ankle pulse wave velocity (baPWV) in individuals with stable COPD within a community setting.
This is a three-arm, parallel-group, assessor-blinded, randomized controlled trial with an eight-week intervention period and a 24-week follow-up. The trial will recruit a total of at least 162 participants with stable COPD. All participants will undergo arterial stiffness assessment using an atherosclerosis detector. Eligible participants will then be randomized into either a control group or one of two intervention groups: an H-IMT group combined with aerobic and resistance trainin, or an H-IMT group alone. The primary outcome is the baPWV at eight weeks. Secondary outcomes include baPWV at 4, 16, and 32 weeks, along with self-reported lifestyle factors, sleep quality, mental health outcomes, self-efficacy, implicit health attitudes, quality of life, and clinical outcomes at 4, 8, 16, and 32 weeks. The main analysis will follow the intention-to-treat principle, with the difference in outcome between groups analyzed using multi-level regression at eight weeks.
This study will provide evidence on the effects of H-IMT and combined exercise interventions for individuals with COPD in a community setting, offering insights into the use of integrated approaches to enhance cardiovascular health among community-dwelling residents.

心血管疾病是慢性阻塞性肺疾病（COPD）最常见且具有临床意义的合并症之一。运动已被证明可降低心血管疾病风险，而高强度吸气肌训练（H-IMT）已成为改善COPD患者动脉僵硬度的一种有前景的干预措施。然而，关于H-IMT单独或与运动联合对降低COPD患者动脉僵硬度影响的随机对照试验（RCT）证据有限。我们设计了一项三臂RCT，以评估H-IMT单独及与运动联合在社区环境中降低稳定期COPD患者肱踝脉搏波速度（baPWV）的有效性。
这是一项三臂、平行组、评估者盲法的随机对照试验，干预期为8周，随访期为24周。该试验将总共招募至少162名稳定期COPD患者。所有参与者将使用动脉粥样硬化检测仪进行动脉僵硬度评估。符合条件的参与者将被随机分为对照组或两个干预组之一：H-IMT组联合有氧运动和抗阻训练，或单独的H-IMT组。主要结局是8周时的baPWV。次要结局包括4、16和32周时的baPWV，以及自我报告的生活方式因素、睡眠质量、心理健康结局、自我效能感、隐性健康态度、生活质量，以及4、8、16和32周时的临床结局。主要分析将遵循意向性分析原则，使用多水平回归分析8周时组间结局差异。
本研究将为社区环境中COPD患者的H-IMT及联合运动干预效果提供证据，为采用综合方法促进社区居民心血管健康提供见解。
