Scientists working with individuals with ADHD have adapted approaches from research on neurotypical populations to understand the effects of exercise on reducing ADHD-related symptoms. To advance this research area further and enhance the therapeutic potential of exercise for managing ADHD symptoms, this editorial perspective offers the following recommendations: More research is required to better understand the neural markers of exercise interventions for ADHD and the inter-relation between changes in ADHD-related neural mechanisms and alterations in behavioural and cognitive symptomatology. Researchers should consider user perspectives and incorporate social support activities when developing exercise programmes for ADHD and Researchers should evaluate exercise as a stand-alone treatment approach using high-quality and well-designed clinical trials.</p>","PeriodicalId":187,"journal":{"name":"Journal of Child Psychology and Psychiatry","volume":null,"pages":null},"PeriodicalIF":6.5,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141553821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
