Feasibility of the JOIN4JOY Programme to Reduce Sedentary Behaviour and Increase Physical Activity in Older Adults.

"The intervention protocol derives from a previous, extensive, co-creation phase involving end-users as well as relatives, experts, professionals working working with older adults, university students and researchers.~It will be based on a structured group-based PA programme supervised by trained professionals, tailored to participants' needs to include joyful components combined with self-management strategies to encourage behaviour change also beyond the sessions. All participants (including end-users but not only) will also be encouraged to join virtual communities of practice (VCoP) for further support and knowledge exchange."
