Physical activity is important for healthy ageing. Despite strong evidence on the benefits of physical activity for health and well-being, physical inactivity remains a significant problem among older adults. This study aims to determine the feasibility and acceptability of implementing an online volunteer-led group exercise for older adults.
A quasi-experimental mixed-methods approach will be used in this study. A training programme will be developed to train volunteers to deliver online group exercises to older adults aged >65 years (n=30). The primary outcome is the feasibility of implementing the intervention. This will be assessed by the number of volunteers recruited, trained, and retained at the end of the study, and the number of exercise sessions delivered and completed by participants. Secondary outcomes include physical activity levels measured using the Community Health Model Activities Programme for Seniors questionnaire, Barthel Index, EQ-5D-5L as a measure of health-related quality of life, SARC-F to determine sarcopenia status, and PRIMSA-7 to determine frailty status. Outcomes will be measured at baseline and at 6 months.Qualitative interviews will be conducted with volunteers(n=5), older adults (n=10) and family members (n=5) to explore their views on the intervention.
Simple descriptive statistics will be used to describe participant characteristics, the feasibility of the study and the impact of the intervention on health outcomes. Parametric(t-test) or non-parametric(Mann-Whitney U test) statistics will be used to analyse continuous variables. χ test will be used for categorical variables. Qualitative data will be analysed using an inductive thematic analysis approach.
This study received ethical approval from the University of Southampton Faculty of Medicine Ethics Committee and Research Integrity and Governance committee (ID: 52 967 .A1). Study findings will be made available to service users, voluntary organisations and other researchers who may be interested in implementing the intervention.

身体活动对健康老龄化很重要。尽管有大量证据表明身体活动有益于健康和幸福感，但老年人身体活动不足仍然是一个严重的问题。本研究旨在确定为老年人实施在线志愿者主导的团体运动的可行性和可接受性。
本研究将采用准实验性混合方法。将制定一项培训计划，培训志愿者为 65 岁以上（n=30）的老年人提供在线团体运动。主要结局是干预措施的可行性。这将通过招募、培训和保留在研究结束时的志愿者人数，以及参与者完成的运动课程数量来评估。次要结局包括使用社区健康模型活动计划老年人问卷测量的身体活动水平、巴氏指数、EQ-5D-5L 作为健康相关生活质量的衡量标准、SARC-F 确定肌肉减少症状态以及 PRIMSA-7 确定虚弱状态。结果将在基线和 6 个月时进行测量。将对志愿者（n=5）、老年人（n=10）和家庭成员（n=5）进行定性访谈，以探讨他们对干预措施的看法。
将使用简单描述性统计数据描述参与者特征、研究可行性以及干预对健康结果的影响。连续变量将使用参数（t 检验）或非参数（曼-惠特尼 U 检验）统计进行分析。分类变量将使用 χ 检验进行分析。定性数据将使用归纳主题分析方法进行分析。
本研究获得了南安普顿大学医学院伦理委员会和研究诚信与治理委员会的伦理批准（ID：52 967 .A1）。研究结果将提供给可能有兴趣实施干预措施的服务用户、志愿组织和其他研究人员。
NCT04672200。
