This 3 year project aims to design, test, and evaluate digital tools to facilitate structured physical activity programs for older adults. It will examine using digital approaches for two existing initiatives: intergenerational physical activity (IGPA) and sports-based intergenerational reminiscence (SBIR). The project will involve co-production groups of older adults and younger people providing input into digital design and testing products. It will also involve working with an existing program called "Generations Active Together" that has university students lead physical activity sessions for older adults. Measures will assess experiences, attitudes and capacities of both older and younger participants.
