Fidelity and feasibility of a multicomponent physical activity intervention in a retirement community.

This pilot study examined the fidelity and feasibility of a multicomponent physical activity intervention in a retirement community. Eighteen older adults participated in an 8-week intervention. The intervention included offering group exercise lessons, combined with providing participants wearable activity trackers. Quantitative and qualitative data were collected to assess the feasibility and fidelity. The retention of the study was 83.3% and the average attendance of group lessons was 88.2%. Participants wore the activity trackers on 93.9% of the required days. Individual interviews indicated that participants were generally satisfied with the intervention. However, the Tai Chi session of exercise lessons and the activity trackers were not favored by the majority of the participants. Future interventions should provide tailored and adaptable exercise programs to meet the various physical health conditions of older adults and ease the use of technology to facilitate behavior change.
