项目摘要

DESCRIPTION (provided by applicant): People with moderate to severe chronic obstructive pulmonary disease (COPD) experience intense symptoms of dyspnea when they use their arms and shoulders. To control the dyspnea people avoid the use of their upper extremities and ultimately experience a significant loss of upper body (UB) strength and a decrease in functional performance, reflected by a decrease in the level of activities performed on a daily basis. The purpose of this research is to examine the effects of UB strength training with a self-efficacy intervention to enhance adherence. This is an experimental study with random assignment of subjects to one experimental and two control groups: (a) UB strength training with self-efficacy intervention (experimental), (b) UB strength training with health education (control 1) and (c) armchair fitness exercises with health education (control 2). The interventions are four months in duration with three booster sessions scheduled during a 12 month follow up period. Each subject will be studied for a total of 16 months. The primary specific aims are to compare the short (4 months) and long term (12 months after termination of structured training) effects of the above interventions in terms of the following dependent variables: UB strength (one-repetition maximum), dyspnea during physical activities (Chronic Respiratory Disease Questionnaire) and functional performance (Functional Performance Inventory). Secondary aims are to examine the effects in terms of inspiratory muscle strength, exercise-related self-efficacy, and adherence to UB strength training. Additionally dual energy x-ray absorptiometry will be used to document changes in UB muscle mass (fat free soft tissue). Dual accelerometers (arm and waist) will be used to verify self-report of exercise adherence at home during the 12 months follow-up. The sample will be 120 people with moderate to severe COPD who experience dyspnea with UB activities, 40 per group. Researchers performing strength tests will be blinded to group assignment. This research is innovative in that it examines the effects of a comprehensive upper body strength training with weight lifting (8 exercises) and combines it with a theory-based self-efficacy intervention to promote adherence to training. This is important because people with COPD experience exacerbations that adversely affect adherence. Previous research in this area does not address the effect of multiple weight lifting exercises and long-term adherence.

描述(申请人提供)：患有中度至重度慢性病的人阻塞性肺病(COPD)会出现严重的呼吸困难症状当他们使用手臂和肩膀的时候。为了控制呼吸困难，人们避免使用他们的上肢，并最终经历显著的丧失上半身(UB)力量和功能表现下降，反映为每天进行的活动水平的减少。目的这项研究的目的是检查UB力量训练的效果自我效能干预提高依从性。这是一项实验性研究。将受试者随机分配到一个试验组和两个控制组： (A)自我效能干预的UB力量训练(试验性)，(B)UB 力量训练和健康教育(对照1)和(C)扶手椅健身运动配合健康教育(对照2)。干预措施为期四个月在为期12个月的随访中计划进行三次强化治疗句号。每个科目将进行为期16个月的研究。初级阶段具体目标是比较短期(4个月)和长期(12个月在有组织训练结束后)上述干预措施的效果下列因变量的术语：UB强度(一次重复最多)，体力活动时呼吸困难(慢性呼吸系统疾病问卷)和功能性能(功能性能清单)。次要目标是检查吸气肌的影响。力量、运动相关的自我效能感和对UB力量的坚持训练。此外，还将使用双能x射线吸收法来记录UB肌肉质量(无脂肪软组织)的变化。双加速度计 (手臂和腰部)将用于验证锻炼依从性的自我报告在家中进行了12个月的随访。抽样调查对象为120人伴有UB活动的呼吸困难的中至重度COPD患者，40% 一群人。进行力量测试的研究人员将对小组视而不见任务。这项研究的创新之处在于它考察了一种举重综合上身力量训练(8个练习) 并将其与基于理论的自我效能干预相结合，促进坚持训练有素。这一点很重要，因为有COPD经验的人对遵守产生不利影响的恶化。这一领域的先前研究没有解决多次举重练习和长期举重的效果坚持不懈。
