Abstract
INTRODUCTION: The health benefits of physical activity are well established; however, most older people are not sufficiently physically active. Despite the availability of various physical activity interventions and programs, implementation of effective prevention strategies to reduce older people's physical inactivity are lacking. The ENJOY IMP-ACT project is an implementation research project, based on a previous evidence-based physical and social activity program utilising specialised outdoor exercise equipment (the Seniors Exercise Park) for older people. The ENJOY IMP-ACT aims to increase participation in physical activity to improve health outcomes for older people in Victoria, Australia. METHOD: The ENJOY IMP-ACT is a hybrid II implementation-effectiveness pre-post mixed method study design. Five local governments (6 public sites/parks) will undergo a 3-month control period followed by 9-months implementation intervention (TERM framework intervention: Training, Engagement, Resources development, Marketing and promotion), and a maintenance phase (3 months). Various methodologies will be employed throughout the project at each site and will include direct observations of park users, intercept surveys with park users, online access monitor platform (using an online app), interviews with stakeholders and exercise program leaders, a process evaluation of physical activity programs, a social return-on-investment analysis, and other related activities. DISCUSSION: Through the implementation framework design, the ENJOY IMP-ACT is uniquely placed to translate an evidenced-based physical and social activity program into real world settings and increase physical activity among older people. If successful, this program will inform scale up across Australia with the goal of improving the health and wellbeing of older people.
