Investigating the Feasibility of a Physical Activity (tele)coaching Intervention in Patients with Non-small Cell Lung Cancer: an Explorative Study

A semiautomated tele coaching program (application installed on a smartphone device with real time feedback and motivational messages) and a step counter (Fitbit Charge 4) providing direct feedback on total daily number of steps, walking time, time in at least moderate PA and movement intensity during walking.

A telecoaching program using a step counter (Fitbit Charge 4) without this custom smartphone application but with the Fitbit application. This intervention will be more focused on weekly personal feedback from a coach by telephone.
