Comparative Effectiveness of Prescribed Adapted Physical Activity (APA), Either Practiced Independently After Training, or Supervised by an APA Teacher, on Glycemic Regulation in People With Unbalanced Type 2 Diabetes.

After the initial training in adapted physical activity (APA), patients will receive regular support from an APA instructor, and they will be asked to participate in 3 sessions per week of APA, if possible in a Sport-Health center close to their home, for the entire duration of the study. The content of the additional APA sessions (up to 2 additional sessions per week) can be discussed with the APA instructor. They will also be asked to return to the study center for a visit at 3 months (Visit 3) to assess the effect of the APA conducted during this period
