Physical activity intervention with connected devices
DeviceParticipants randomized in the intervention arm will receive recommandations in physical activity. They will also receive an activity tracker Withings Steel to wear during 6 months. The tracker will be connected to the "Withings Health Mate" application and the ABLE02 application. Participants will be encouraged to practice at least three walking sessions weekly of more than 10 consecutive minutes. Concerning the number of steps per day, the first objective will be determined according to the 6-min walking distance and to participants' preferences and capacities. The objective will be recalculated monthly according to the number of steps performed the previous week and will be adapted by the physical activity (PA) instructor and participants. Phone calls with the participants are regularly planned. Weekly quizzes on PA and nutrition will be proposed through the ABLE02 application. A messaging system and a phone line will be available for participants to contact the study team.
