Abstract：
UNASSIGNED: There is overwhelming evidence to support the promotion of physical activity in adults in terms of benefits to well-being, physical and mental health. Physical activity guidelines suggest that adults should accumulate at least 150 min of moderate to vigorous physical activity per week. In Ireland, the majority of adults do not achieve these guidelines, with costs to health and economy. \'Move for Life\' (MFL) employs behavioural change techniques delivered by an instructor and peer mentor, using a train-the-trainer (cascade) model. This study will conduct a feasibility cluster randomised controlled trial of the MFL intervention for modifying physical activity behaviours in inactive adults aged 45 years and older.
UNASSIGNED: The trial is set in eight Local Sports Partnership (LSP) hubs that have structured physical activity programmes. The hubs are the units of randomisation (clusters), and individuals are the units of analysis (participants). Eligible participants will contact one of the hubs, with each hub running four physical activity programmes. Each programme requires between 12-15 inactive adults, resulting in 48-60 participants per hub. Allowing for 20% dropout rate, an additional 96 people will be recruited giving a maximum sample of 576. The hub will be randomised: true control, usual programme or MFL intervention. The true control group will be given information about physical activity but will not be included in a programme for the duration of the trial; the intervention will involve the instructor training one (or more) of the participants to be a peer mentor using an educational toolkit; and usual care groups will have physical activity classes delivered as normal. Baseline data will collect physical activity measures and follow-up measurements will be obtained at 3 and 6 months. All participants will be asked to wear a device for measuring activity on the thigh (activPAL) for 7 days before commencing the programme and at 3 and 6 months. The primary objective of the study is to investigate if it is feasible to deliver the intervention and collect data on moderate to vigorous physical activity (MVPA) on all participants, thereby providing valuable information to guide sample size calculation for a future, more definitive trial.

摘要：
■有大量证据支持在成年人中促进体育锻炼对福祉的益处，身心健康。身体活动指南建议成年人每周应累积至少150分钟的中度至剧烈的身体活动。在爱尔兰,大多数成年人没有达到这些指导方针，健康和经济成本。“为生活而移动”（MFL）采用了由讲师和同伴导师提供的行为改变技术，使用训练机（级联）模型。这项研究将对MFL干预措施进行可行性整群随机对照试验，以改善45岁及以上不活动的成年人的身体活动行为。
■该试验是在八个具有结构化体育活动计划的本地体育合作伙伴关系（LSP）中心进行的。中心是随机化的单位(集群)，个人是分析的单位（参与者）。符合条件的参与者将联系其中一个中心，每个中心都有四个体育活动计划。每个项目需要12-15名不活跃的成年人，每个中心有48-60名参与者。允许20%的辍学率，另外将招募96人，最多样本为576人。中心将是随机的：真正的控制，常规方案或MFL干预。真正的对照组将获得有关身体活动的信息，但在试验期间不会包括在计划中；干预将涉及指导者使用教育工具包对一名（或多名）参与者进行培训，使其成为同伴导师；通常的护理小组将按正常情况进行身体活动课程。基线数据将收集身体活动测量值，并在3个月和6个月获得后续测量值。所有参与者将被要求佩戴测量大腿活动的装置（activPAL）7天，然后开始该计划，并在3个月和6个月。该研究的主要目的是调查是否可行的干预措施，并收集所有参与者的中度至剧烈体力活动（MVPA）的数据。从而提供有价值的信息来指导未来的样本量计算，更明确的审判。
