Get Ireland Active! – the National Physical Activity Plan for Ireland (NPAP) was launched on 14 January, 2016. The key target identified in the Plan is to increase the number of people taking regular exercise by 1% per annum over the lifetime of the Plan, to be achieved by making physical activity a normal part of everyday life and giving people more opportunities to be active. The goal is to create an environment where everybody lives, works and plays in a society that facilitates, promotes and supports physical activity, sport and an active way of life, with less time spent being inactive. An Implementation Group was established in 2016 to progress the recommendations of the Plan. It is co-chaired by the Department of Health and Department of Tourism, Culture, Arts, Gaeltacht, Sport and Media (DTCAGSM). It includes representatives from the Departments of Children, Equality, Disability, Integration and Youth (DCEDIY), Education (DoE), Housing, Local Government and Heritage (DHLGH). The Department of Rural and Community Development (DRCD) joined the Implementation Group in early 2019. The HSE, Sport Ireland, the Federation of Irish Sport, the Local Government Management Association and the academic sector are also represented. Implementation of the NPAP has been overseen by the Implementation Group since 2016. Three previous Reports, giving overviews of the achievements under the NPAP from 2017 - 2019, have been published and can be accessed on the Healthy Ireland website. This fourth Summary Report provides an updated overview, highlighting some of the positive developments which took place in 2020 to promote physical activity in Ireland, and details the impacts of the Covid-19 pandemic in this area.
