Ready Steady 3.0试验旨在测试两种行为改变干预成分在8周身体活动干预中对老年人身体活动（PA）的主要和交互作用。每个组成部分都由行为改变策略组成，这些策略强调两种不同的基于证据的方式来激励老年人积极参与：人际关系和自我认知。在一项2 × 2全因子试验中，将308名≥ 70岁的成人随机分配至4种条件之一，其中两个因素代表接受（否，是）人际或自我行为改变策略。参与者还将获得两个核心干预组件：适用于小团体的奥塔哥运动计划和PA监视器。将在社区环境中举行的8次每周一次的小组会议上提供各种条件的干预措施。将在基线和干预后（1周、6个月和12个月）评估客观测量的PA主要结局和福尔斯次要结局以及生活质量。研究结果将使行为变化的内容，有助于身体活动的结果在老年人的身体活动干预识别。这项研究是第一个使用MOST框架来指导老年人以社区为基础的身体活动干预的发展，以减少低PA和福尔斯的公共卫生问题。研究结果将使老年人的PA干预中的行为改变内容的优化，反过来，其他PA干预老年人。
The Ready Steady 3.0 trial is designed to test the main and interactive effects of two behavior change intervention components, within an 8-week physical activity intervention, on older adults’ physical activity (PA). Each component is comprised of behavior change strategies that emphasize two different evidence-based ways to motivate older adults to be active: interpersonal and intrapersonal. 308 adults ≥ 70 years old will be randomized to 1 of 4 conditions in a 2 × 2 full factorial trial in which the two factors represent the receipt (No, Yes) of interpersonal or intrapersonal behavior change strategies. Participants will also receive two core intervention components: the Otago Exercise Program adapted for small groups and a PA monitor. Interventions across conditions will be delivered during 8 weekly, small group, meetings in community settings. The primary outcome of PA, measured objectively, and secondary outcomes of falls and the quality of life will be assessed at baseline and post-intervention: 1 week, 6 months, and 12 months. Findings will enable the identification of behavior change content that contributes to physical activity outcomes within a physical activity intervention for older adults. This study is one of the first to use the MOST framework to guide the development of a community-based physical activity intervention for older adults to reduce the public health problems of low PA and falls. The results will enable the optimization of behavior change content within a PA intervention for older adults and, in turn, other PA interventions for older adults.
