Study quality was assessed using the Critical Appraisal Skills Programme checklist.\u0000 \u0000 \u0000 \u0000 A total of 1538 articles were screened, with seven studies included (n=161 participants across six countries; overall study quality rated ‘high’). Semi-structured interviews and focus groups were the predominant methods. Key findings encompassed barriers to PA/exercise uptake and maintenance including: lack of awareness of MAFLD, which lowered risk perception; lack of information provision regarding the role and importance of PA/exercise for MAFLD management; lack of resources, tailored exercise plans or referrals; multiple comorbidities and symptoms including obesity, musculoskeletal conditions, pain and fatigue; ambivalence of perceived exercise capabilities and low exercise-related self-efficacy; lack of time and competing priorities. Reported enablers of PA/exercise included: accountability to themselves (e.g., habit forming) and to the healthcare professional; social support from family, friends, and healthcare providers; the experience of symptom relief and holistic benefits.\u0000 \u0000 \u0000 \u0000 This study translated first-hand experiences and perceptions of physical activity and exercise for people with MAFLD, identifying priorities to target for improved uptake and maintenance.\u0000","PeriodicalId":92070,"journal":{"name":"Journal of clinical exercise physiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141041460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
