Objectives With the emergence of SARS-CoV-2 a global pandemic impacted on health promotion, overlapping and hindering efforts to overcome the worldwide pandemic of lacking physical activity (PA). Nationwide lockdowns, the closure of public facilities and sports venues, made it significantly more difficult to sustain community-run PA projects. In our case study, we explore (a) under which circumstances a community-basedhealth promotion project can be maintained during crisis and (b) what resilience capacities are important for community project coordinators to deal with those aggravating circumstances. Methods Our case study looks at a community-based project called BIG, an exercise promotion project for women in difficult life circumstances. The case study was conducted between July 2021 and January 2022 with six municipalities implementing the project. Following a triangulation approach, we used minutes from short exchanges (n=17) with community project coordinators, information brochures about current exercise classes (n=6) and semi-structured qualitative interviews with project coordinators (n=6). All data were analyzed using the framework approach. Results All sites showed a high level of willingness to adapt to the pandemic situation and to maintain the project as best as possible. Findings highlight that coordinators whose work routine was characterized by intense relationship management with participants and trainers demonstrated higher levels of adaptive and absorptive capacities on an individual level than coordinators of those communities with less social cohesion. At a community level, important resources for strengthening adaptive and absorptive resilience capacities were job security of the coordinators, sufficient financial resources to adapt classes to changing circumstances, and a supportive organizational climate in the coordinators' working environment to allow them to react flexibly according to current pandemic regulations. Conclusion Despite high resilience capacities especially on an individual level, the low-threshold nature of the project could not be maintained at a pre-pandemic level. For many women, participation in the project was no longer possible at times. Awareness should be raised in communities that PA promotion programs are crucial to strengthening physical and mental health, even in times of crisis. It seems necessary to find permanent funding options for such programs, to integrate them permanently into municipal structures.
