Physical Activity Behaviour in Solid Organ Transplant Recipients: Proposal of Theory-Driven Physical Activity Interventions

Physical inactivity is highly prevalent after solid organ transplantation and leads to unfavourable outcomes. This review aimed to understand posttransplant physical activity behaviour and propose physical activity interventions. Michie’s Behavioural Change Wheel was applied, in which the Context and Implementation of Complex Interventions framework, the Capability-Opportunity-Motivation and Behaviour model, and the Theoretical Domains Framework were embedded. Various contextual factors were found to modulate physical activity behaviour. Promising strategies to promote long-term physical activity included (i) tailoring of physical activity programs to patients’ abilities and preferences; (ii) incitement of intrinsic and autonomous motivation to change; (iii) SMART goals setting (e.g., Specific, Measurable, Achievable, Realistic, Timebound), (iv) autonomy-supportive co-design of action plans; (v) foster new habit formation; (vi) self-monitoring of physical activity; (vii) follow-up opportunities for evaluation and adjustment; (viii) education of transplant recipients, healthcare providers, and the patients’ social network; (iv) improvement of self-efficacy through incremental successes, verbal persuasion, peer modelling, and awareness of exercise-related bodily signals; (x) providing physical activity opportunity within patients’ social and environmental setting; (xi) encouragement and support from patients’ social network and healthcare providers; and (xii) governmental action that alleviates financial barriers and restructures the physical environment to promote physical activity. These new insights may contribute to physical activity program development for transplantation recipients.
