Sports mega events and physical activity legacies: what's the evidence?
I recently published a systematic literature review that explores the potential of sports mega events, such as the Olympic and Paralympic Games, for increasing population physical activity. As a researcher based in the super aging society of Japan, I have a significant interest in how large scale interventions can be developed to promote health behavior change. Considering the significant national interest in the Tokyo 2020 Olympic and Paralympic Games, there may be potential to leverage this event (through public health marketing, role modelling, infrastructure investment etc.) to improve sports and physical activity participation for the masses. Surprisingly, despite over a century of modern Olympiads there is relatively limited high-quality research in this area. Among published studies, there is scant evidence that hosting a sports mega event has a significant impact on population physical activity. Interestingly, the only compelling evidence for such an outcome has been found in Japan as a legacy of the 1964 Tokyo Games. Will this achievement be repeated in 2020 and beyond, and what is the role for event organizers and researchers?
Title: Sports mega-event legacies and adult physical activity: a systematic literature review and research agenda.
Abstract: Sports mega-events, such as the Olympic and Paralympic Games, have the potential to inspire increases in population physical activity, yet investigations concerning such legacy outcomes have been inconclusive. This may be due to research design limitations or inconsistent leveraging of potential hosting benefits by event organizers. This systematic review aims to identify current knowledge about the capacity of sports mega-events to inspire increases in physical activity participation among adult populations and develop a research agenda to guide future legacy evaluations. Peer-reviewed, English-language studies published on or after the year 2000 were considered. Six academic databases and grey literature sources were searched, and articles were assessed for methodological quality. Reporting followed PRISMA conventions for systematic reviews. Nine studies were selected after quality evaluation, including previous reviews, quantitative and qualitative research. Most studies found no evidence for long-term physical activity outcomes associated with hosting sports mega-events, although limitations and gaps were identified. These included lack of longitudinal or cohort studies, limited differentiation of subpopulations, use of non-validated instruments, and lack of triangulation for qualitative findings. Only one cohort study from Japan identified sustainable and significant physical activity increases resulting from a previous sports mega-event. Considering theory, the commonly cited Demonstration Effect was reportedly an unreliable framework, although the Festival Effect and Social Ecological Model appear more promising for anticipating and explaining legacy effects. With less than two years until the Tokyo 2020 Olympiad, it is appropriate to commence high-quality legacy research drawing on lessons learned from previous studies.
