Physical Activity Enhancement in the Elderly

描述(由申请人提供)：斯特拉斯博士过去和现在的研究重点一直是体力活动(PA)评估以及PA和健康指数。他的眼前目标是获得新的专业技能，帮助他实现一个长期目标，即在PA和老年人健康方面开发一个成功的独立、由外部资金资助的研究项目。概述的K01职业发展奖(CDA)将为斯特拉斯博士提供必要的培训，以实现他的长期目标。斯特拉斯博士的研究CDA包括获得与他提出的研究计划相关的新技能，并对其进行补充，其中包括：a)组织活动，包括正式的课程工作；b)出席科学会议和期刊俱乐部并发表演讲；c)与他的赞助商和指导团队进行定期互动。斯特拉斯博士提出的培训和研究计划的直接环境应该是非常好的。确定的赞助商和指导团队非常有资格提供必要的指导，并投入大量时间帮助斯特拉斯博士成功实现他的职业目标。研究1和研究2的总体目标将寻求完善专门针对老年人的客观PA评估方法。在实验上，这将包括在标准化活动和不同生活方式相关活动中建立标准相关效度，建立与年龄相适应的方程，将客观监测回归到测量的PA。信度和结构效度将进一步建立。为了获得与研究3相关的准确的PA结果，这些研究是必要的。研究3的总体目的是确定旨在增加老年人PA以及健康和幸福感的个体化、邮件中介的干预措施的相对有效性。实验设计将由一个延迟控制臂和三个实验干预组成。干预1：连续计步器反馈；干预2：动机匹配的邮寄反馈；以及干预3：干预1和干预2的交互作用。这项实验设计产生的新的创新信息是，它将允许评估连续计步器反馈、个人定制的邮件中介干预的有用性以及两者的综合效果。这种介入设计在老年人中既新颖又创新。

DESCRIPTION (provided by applicant): Dr. Strath's past and current research focus has been on physical activity (PA) assessment and PA and health indices. His immediate goal is to acquire new professional skills to help him achieve a long-term goal of developing a successful independent extramurally-funded research program in PA and health for the elderly. The outlined K01 Career Development Award (CDA) should provide Dr. Strath with the required training to achieve his long-term goal. Dr. Strath's research CDA consists of acquiring new skills associated with and complimentary to his proposed research plan, which consists of: a) structured activities including formal course work; b) attendance and presentations at scientific meetings and journal clubs; and c) regular interactions with his sponsors and mentoring team. The immediate environment for Dr. Strath's proposed training and research plan should be excellent. The sponsors and mentoring team identified are exceptionally qualified to provide the necessary mentoring and have dedicated a substantial time commitment to helping Dr. Strath succeed in his professional goals. The general aim of studies 1 and 2 will seek to refine objective PA assessment methods specific to the elderly. Experimentally, this will consist of establishing criterion related validity during standarized activities, and different lifestyle related activities, producing age appropriate equations to regress objective monitoring to measured PA. Reliability and construct validity will be further established. These studies are necessary to obtain accurate PA outcomes associated with study 3. The general aim of study 3 is to determine the relative effectiveness of individually- tailored, mail mediated, interventions designed to increase PA and health and well-being in the elderly. Experimental design will consist of a delayed-control arm and three experimental interventions. Intervention 1: continuous pedometer feedback; Intervention 2: motivationally-matched mailed feedback; and Intervention 3: the interaction of intervention 1 and intervention 2. New innovative information arising from this experimental design is that it will permit an evaluation of continuous pedometer feedback, the usefulness of individually-tailored, mail mediated interventions, and the combined effects of both. This intervention design is both novel and innovative in the elderly.
