Effect of Walking With Music in Obese People (BeatMove)

This program involves outdoor walking sessions, conducted 5 times a week for 15 to 30 minutes each, over a consecutive 3-month period using the BeatMove device. The device can be adjusted to deliver music or not, and the music can either be synchronized to the participant's walking pace or randomly timed. During the week preceding self-rehabilitation, participants will wear a thigh-mounted accelerometer to establish a baseline representative of their daily habits. Before each walking session, participants will assess their motivation using a visual analog scale within the application. After each session, they will evaluate their perceived exertion using the Borg Scale. In the BeatMove group, the music delivered will be tailored to match the walking pace of the participants. Throughout the session, the music rhythm will subtly increase by 20% to accelerate the participant's walking pace, thereby guiding them towards their optimal cadence based on their assessed level and motivation at the start of the session. In the group with randomly timed music, the music delivery does not consider the participant's state and plays random music. Finally, in the group without music, the walking self-rehabilitation program will be guided solely by the audio instructions provided by the application. In all three groups, participants will be equipped: Throughout the day with a thigh-mounted "fibion sens" accelerometer. During the walking self-rehabilitation session with ankle step sensors to record walking parameters while delivering music tailored to their walking pace.
