Understanding the impact of the installation of outdoor fitness equipment and a multi-sports court on park visitation and park-based physical activity: A natural experiment

This natural experiment examined the impact of the installation of outdoor fitness equipment and one multi-sports court in a park located in Melbourne, Australia on park visitation and park-based physical activity compared to a control park. Barriers and facilitators to use of this equipment among adult park visitors were also explored. Park visitation and moderate-vigorous physical activity (MVPA) in the two parks were assessed before (T1, 2016) and after the intervention (T2, 2019) using observations of park visitors from children to older adults across four days (7.30am-5.00pm). The relative change in observed counts in visitors from T1-T2 in the intervention park compared to the control park was used to assess the effect of the park refurbishment. Intercept surveys regarding barriers and facilitators were conducted with adult park visitors. Over the three-year period, total visitor counts increased by 16% and the number of park visitors observed engaging in MVPA increased by 24% in the intervention park. However, there were no significant intervention effects on total visitor counts (IRR = 0.89, 95%CI: 0.62, 1.30) or MVPA (IRR = 0.80, 95%CI: 0.53, 1.19) relative to the control park. Examples of frequently mentioned facilitators to increase use of the sports court and fitness equipment included having someone to use the facilities with and instructional signage, and common barriers included poor weather and lack of time. The impact of the park upgrade on visitation and MVPA was not significant. A better understanding of the broader appeal of outdoor fitness equipment and a multi-sports court among different segments of the population is needed.
