PROJECT PRIME--APPLICATIONS OF LIFESTYLE EXERCISE

描述 这项研究是一项随机试验，旨在评估两种生活方式的身体状况。 活动干预。 生活方式方法基于以下阶段： 动机准备模型和社会认知理论，旨在 帮助久坐的成年人达到推荐的30分钟， 每天进行中等强度的体力活动。 以前的工作 研究人员发现，生活方式的身体活动干预， 在“行为组过程”设置中交付，导致 体力活动和改善临床变量，如脂蛋白 血压和身体成分。 本申请提出了一个三组随机试验，以开发和测试 生活方式干预进一步降低强度和成本， 面对面的干预。 原始的小组会议生活方式方法 （PRIME G组）将与提供以下干预措施进行比较： 通过邮件和电话进行咨询和指导（PRIME C -通讯员）。 还将有一个标准护理对照（PRIME SC），其中受试者 获得为期6个月的YM/YWCA会员资格和一般健康通讯。 研究人员计划招募并随机分配总共243名男性， 女人的三个条件 拟议项目PRIME是一项为期24个月的研究，最初为期6个月， 强化干预和18个月的维持和随访期。 主要的研究假设是， 干预将有效地增加身体活动， 耐力健身在最初健康的久坐不动的男性和女性， 密集的小组会议生活方式的方法，并将这样做，在显着 成本更低。

DESCRIPTION The proposed study is a randomized trial to evaluate two lifestyle physical activity interventions. The lifestyle approach is based on the stages of motivational readiness model and social cognitive theory, and is designed to help sedentary adults achieve the recommended 30 minutes of at least moderate intensity physical activity each day. Previous work by the investigators has found that a lifestyle physical activity intervention delivered in a "behavioral group process" setting, resulted in increases in physical activity and improvements in clinical variables such as lipoprotein profile, blood pressure, and body composition. This application proposes a three group randomized trial to develop and test the lifestyle intervention further by decreasing the intensity and cost of face-to-face interventions. The original group meeting lifestyle approach (PRIME G - group) will be compared with an intervention that provides counseling and guidance by mail and telephone (PRIME C - Correspondent). There will also be a standard care control (PRIME SC) in which participants are given a 6-month YM/YWCA membership and a general wellness newsletter. The investigators plan to recruit and randomly assign a total of 243 men and women to the three conditions. The proposed project, PRIME, is a 24-month study, with initial 6-month intensive interventions and an 18-month maintenance and follow-up period. The primary research hypothesis is that the correspondent lifestyle intervention will be as effective in increasing physical activity and endurance fitness in initially healthy sedentary men and women as the more intensive group meeting lifestyle approach and will do so at significantly less cost.
