美国心力衰竭协会（HFSA）2010年指南建议心力衰竭（HF）患者每周5天进行30分钟有监督的中等强度运动。需要创新的计划来帮助HF患者坚持长期锻炼。这项前瞻性随机两组重复测量实验设计的目的是确定行为运动训练干预对心力衰竭患者18个月时长期坚持运动的疗效。将在3年内招募246例心力衰竭受试者的样本量。所有受试者在随机化前的3周导入期内接受心肺运动试验和9次监督运动训练。完成9次训练中至少6次的受试者被随机分配到HEART Camp干预组（HC）或标准护理（SC）运动组。HC干预组接受认知行为策略，解决知识，态度，自我效能，行为自我管理技能和社会支持的干预组成部分。SC组在18个月的研究期内可以使用锻炼设施和常规设施工作人员。主要目的是评估HEART Camp对锻炼坚持性的影响，我们的中心假设是HC组在18个月时对锻炼的坚持性将显着更好。次要目的包括评估HEART Camp干预措施的哪些组成部分介导了干预措施对依从性的影响;评估HEART Camp对特定健康结果的影响;探索选定的人口统计学变量（种族，性别，年龄）作为HEART Camp干预措施对依从性影响的潜在调节因素;并探索使运动依从性情境化的感知和经验。HEART Camp干预是第一次测试旨在改善HF患者长期坚持运动行为的多成分干预。改善长期坚持锻炼是确保所需运动剂量的合理第一步，这对于实现有益的健康结果和降低这种负担沉重的慢性疾病的成本是必要的。Clincaltrials.gov NCT01658670。
Adherence to the Heart Failure Society of America (HFSA) 2010 guidelines recommending 30 minutes of supervised moderate intensity exercise five days per week is difficult for patients with heart failure (HF). Innovative programs are needed to assist HF patients to adhere to long-term exercise. The objective of this prospective randomized two-group repeated measures experimental design is to determine the efficacy of a behavioral exercise training intervention on long-term adherence to exercise at 18 months in patients with heart failure. A sample size of 246 subjects with heart failure will be recruited over a 3 year period. All subjects receive a cardiopulmonary exercise test and 9 supervised exercise training sessions during a 3 week run-in period prior to randomization. Subjects completing at least 6 of 9 training sessions are randomized to the HEART Camp Intervention group (HC) or to a standard care (SC) exercise group. The HC intervention group receives cognitive-behavioral strategies that address the intervention components of knowledge, attitudes, self-efficacy, behavioral self-management skills and social support. The SC group is provided access to the exercise facility and regular facility staff for the 18 month study period. The primary aim is to evaluate the effect of HEART Camp on adherence to exercise, with our central hypothesis that the HC group will have significantly better adherence to exercise at 18 months. Secondary aims include evaluating which components of the HEART Camp intervention mediate the effects of the intervention on adherence; evaluating the effect of HEART Camp on specific health outcomes; exploring selected demographic variables (race, gender, age) as potential moderators of the effect of the HEART Camp intervention on adherence; and exploring the perceptions and experiences that contextualize exercise adherence. The HEART Camp intervention is the first to test a multi-component intervention designed to improve long-term adherence to exercise behavior in patients with HF. Improving long-term adherence to exercise is the logical first step to ensure the required dose of exercise that is necessary to realize beneficial health outcomes and reduce costs in this burdensome chronic illness.
