Background:
Although the health benefits of exercise for older adults are widely recognized, physical inactivity is still common among older adults. Further clarification of the factors affecting exercise adherence is needed to develop more effective exercise interventions in community-dwelling older adults.
Objective:
The purposes of this study were to identify (1) barriers and facilitators of exercise adherence in community-dwelling older adults and (2) behavior change techniques (BCTs) and implementation strategies that are potentially effective in improving adherence.
Methods:
A total of eight databases were searched: PubMed, Web of Science, EMBASE, CENTRAL, PsycINFO, SPORTDiscus, MEDLINE, and Scopus. Studies published from database inception to April 2023 were searched. The quality of the included studies was assessed using the Mixed Methods Appraisal Tool (MMAT). The Capabilities, Opportunities, Motivations, Behavior (COM-B) model and the Theoretical Domain Framework (TDF) were used to identify potential barriers and facilitators. The BCTs were used to identify potential intervention implementation strategies.
Results:
A total of 64 studies were included, including 30 qualitative studies, 12 randomized controlled trials, 12 mixed methods studies, 6 quantitative descriptive studies, and 5 non-randomized trials. 54 factors influencing adherence and 38 potentially effective BCTs were identified from the included studies. The 38 BCTs were further categorized into 8 areas of implementation strategies (tailored exercise program, appropriate exercise environment, multidimensional social support, monitoring and feedback, managing emotional experiences and issues, participants education, enhancing self-efficacy, and exerting participants' autonomy).
Conclusion:
This study identified 54 influential factors affecting exercise adherence and identified 8 areas of intervention strategies (containing 38 BCTs). Further refinement, evaluation, and validation of these factors and strategies are needed in future studies.
