Vulnerable older adults have a high risk of morbidity and mortality. Regular physical activity (PA) can have a positive effect on the health and health-related behavior of this specific target group. However, evidence of the impact and feasibility of community-based PA promotion interventions for vulnerable older adults is still limited.
The BeTaSen (Bewegungs-Tandems in den Lebenswelten Chemnitzer Seniorinnen und Senioren: ein Beitrag zur kommunalen Gesundheitsförderung) study aims to evaluate the (1) impact as well as the (2) feasibility, acceptance, and usefulness of a 12-month low-threshold PA intervention program for community-dwelling vulnerable older adults.
For our population-based prospective observational cohort study, a total of 120 vulnerable older adults (aged 75 years or older) in the area of Chemnitz (Germany) will be recruited to participate in (1) weekly neighborhood-based low-threshold PA meetings with trained mentors (activity tandems) and (2) monthly exercise meetings led by trained exercise instructors. Within the intervention, participants will be encouraged to perform the PA independently. Participants will complete assessments, which will include questionnaires as well as objective measurements of their physical, cognitive, and psychosocial health at 3 different time points (baseline, 6 months after the start, and 6 months after the end of the intervention). Additionally, a process evaluation will be performed, including questionnaires and qualitative interviews, involving the participants, mentors, and municipal project partner representatives.
The BeTaSen project process began in October 2021, with the start of data collection and intervention in August 2022 in the first neighborhoods of the city of Chemnitz. A total of 86 participants were recruited at the time of submission of the manuscript. Longitudinal results are expected by 2025.
This study's results will provide insights on (1) the PA behavior of vulnerable older adults as well as the impact of PA interventions on health-related outcomes such as cognitive, physical, and psychosocial health, and (2) the feasible and useful components of community-based PA interventions. Thus, this pilot study contributes to future recommendations and provides a basis for further research, such as the development of feasible and sustainable target group-specific interventions in community settings.

脆弱老年人的发病和死亡风险较高。定期体育活动（PA）可对这一特定目标群体的健康及与健康相关的行为产生积极影响。然而，针对脆弱老年人的基于社区的体育活动促进干预措施的影响和可行性证据仍然有限。
BeTaSen（开姆尼茨老年人生活世界中的运动伙伴：对社区健康促进的贡献）研究旨在评估一项针对居住在社区的脆弱老年人的为期12个月的低门槛体育活动干预计划的（1）影响以及（2）可行性、可接受性和有用性。
在我们基于人群的前瞻性观察队列研究中，将招募德国开姆尼茨地区总共120名脆弱老年人（75岁及以上），让他们参加（1）每周一次由训练有素的导师指导的基于社区的低门槛体育活动聚会（活动伙伴）以及（2）每月一次由训练有素的运动教练主持的锻炼聚会。在干预过程中，将鼓励参与者独立进行体育活动。参与者将在3个不同时间点（基线、干预开始后6个月和干预结束后6个月）完成评估，评估将包括问卷调查以及对其身体、认知和心理社会健康的客观测量。此外，将进行过程评估，包括问卷调查和定性访谈，涉及参与者、导师和市政项目合作伙伴代表。
BeTaSen项目于2021年10月启动，2022年8月在开姆尼茨市的首批社区开始数据收集和干预。在提交稿件时共招募了86名参与者。预计2025年得出纵向研究结果。
本研究结果将提供有关（1）脆弱老年人的体育活动行为以及体育活动干预对认知、身体和心理社会健康等与健康相关结果的影响，以及（2）基于社区的体育活动干预的可行和有用组成部分的见解。因此，这项试点研究有助于未来提出建议，并为进一步研究提供基础，例如在社区环境中制定可行且可持续的针对特定目标群体干预措施。
