Pilot Study to Evaluate Limitations to Participating in an Exercise Program

本研究的总体目标是筛选生活在社区中的老年人，以确定那些活动能力强但未来残疾风险增加的老年人，评估参与锻炼计划的局限性，并描述合适的锻炼计划类型。需要解决的具体问题包括：1。从电话筛选，到家庭评估，再到诊所检查，三级筛选和招聘计划的有效性如何？说自己能走一英里、能爬楼梯的人，实际能走400米的比例是多少？2. 有多少潜在的符合条件的人（符合下面的筛选标准）已经在进行步行锻炼或进行其他形式的锻炼？3. 哪些疾病、身体缺陷或症状会阻止潜在的符合条件的人参加锻炼项目或项目的某些方面？4. 在那些可以锻炼的人中，他们可以做哪些具体的锻炼，他们可以在什么强度的水平上开始这些锻炼？这群人开始锻炼计划的准备情况如何？哪些疾病、功能和心理社会特征与锻炼准备有关？我们将采用三阶段方法筛选和评估研究对象。本初步研究的对象是符合特定标准的方便样本。受试者将进入筛选过程，直到有100人符合并完成全部三个阶段的评估。

The overarching goals of this research are to screen older persons living in the community to identify those who are mobile but at increased risk of future disability, to evaluate limitations to participating in an exercise program, and to describe the kind of exercise program that would be appropriate. Specific questions to be addressed include: 1. What is the effectiveness of a three-level screening and recruitment program that progresses from a telephone screen, to a home evaluation, to a clinic exam?1.What proportion of people who say that they can walk a mile and climb stairs can actually walk 400 meters? 2. What proportion of potentially eligible people (meeting screening criteria below) are already walking for exercise or doing other forms of exercise? 3. What are the diseases, physical impairments, or symptoms that will prevent potentially eligible people from participating in an exercise program or some aspect of the program? 4. Among those who can exercise, what specific exercises can they do and at what level of intensity can they begin these exercises?5.What is the readiness of this group of persons to begin an exercise program and what disease, functional, and psychosocial characteristics are associated with readiness to exercise? We will screen and evaluate study subjects using a 3-stage approach. The subjects for this pilot study are a convenience sample who meet specific criteria. Subjects will be entered into the screening process until 100 have qualified for and completed the full three stages of evaluation.
