With the increasing prevalence of asthma in children, exercise has become an essential component of asthma management, playing a significant role in improving overall health and quality of life. However, children with asthma face numerous challenges when participating in exercise, including physical limitations due to symptoms, fear of exacerbations and lack of parental support. In addition to these barriers, some factors can promote or facilitate exercise in this population. Therefore, this qualitative meta-synthesis aims to explore these barriers and facilitators through a qualitative meta-synthesis, to provide a basis for developing targeted exercise interventions, optimising asthma management and improving the health status and quality of life of children with asthma.

This qualitative metasynthesis will adhere to the Joanna Briggs Institute (JBI) framework. The final systematic literature search will be performed in the following electronic databases to include publications from their inception until 31 December 2025: PubMed, Embase, CINAHL, Web of Science and the Cochrane Library. The search strategy will include controlled terms and keywords related to ‘asthma’, ‘child’, ‘exercise’ and ‘qualitative research’. The inclusion criteria will comprise qualitative or mixed-methods studies published in English that explore the barriers to and facilitators of exercise participation in children under 14 years of age with asthma, their families or healthcare providers. Grey literature and non-English studies will be excluded. Study selection, data extraction and methodological quality assessment (using the JBI Critical Appraisal Checklist) will be conducted independently by two reviewers. Data will be synthesised using thematic synthesis.

Ethical approval will not be required for this qualitative synthesis, as it solely encompasses data derived from previously published research. Findings will be disseminated through professional networks, conference presentations and submission to a peer-reviewed journal.
