Videoconferencing Adapted Physical Activity in Anorexia Nervosa: a Pilot Study

The primary objectives of the APAREXIM'Pilot study are to evaluate the short- and medium-term effects of a live supervised Adapted Physical Activity (APA) program via videoconferencing on: * Feasibility and acceptability of APA via videoconferencing by the patients. * The primary symptoms of Anorexia Nervosa (AN). The secondary objectives are to evaluate the impact of this program on : * Mental health * Physical condition * Sleep-wake cycle (sleep disturbance and physical hyperactivity) The patients will first undergo an inclusion visit (T0) at the University Hospital of Caen, then a first evaluation session (T1) at the COMETE laboratory in Caen (physical tests, questionnaires, sleep diary, actimetry). They will then be randomly divided into 2 groups: 15 patients who will follow an APA program supervised by videoconference for 8 weeks (AM-APA) at their home, in addition to the usual outpatient treatment, and 15 patients who will benefit only from the classic outpatient treatment (AM-T). All patients will undergo two additional evaluation sessions at one week post-program (T2) and at 3 months post-program (T3).
