Evidence on the reach and impact of the social physical activity phenomenon : A scoping review.

The aim of this study was to conduct a scoping review of parkrun literature for evidence of its reach, health impact and appeal whilst identifying gaps for future research. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR). Six databases were searched according to search terms set a priori. Empirical studies of any design were included if they provided data on participation in, or benefits of, parkrun and were in English. Two authors conducted the searches independently and screened results by title and abstract, followed by full text reviews. A total of 235 records were screened and 15 studies were eligible; 12 were conducted in the UK and three in Australia. Seven were qualitative interview studies, six were quantitative, and two used mixed methods. parkrun reaches groups traditionally underrepresented in other organised sports or physical activity such as women, the insufficiently active and those aged over 35 years. Participants showed sustained improvements in fitness, physical activity levels, and body mass index with a dose-response effect with participation frequency. Qualitative data shows parkrun's location in pleasant environments with opportunities for informal social interaction engages priority groups such as individuals with mental health issues, women and children. The small evidence base suggests parkrun has good reach, and can positively impact participants' health and wellbeing. The data, however, are currently UK-centric and gaps in research on non-participants, long term health impacts and operationally relevant factors should be addressed.
