Anorexia Nervosa
Conditions
Brief summary
Physical hyperactivity is often associated to anorexia nervosa (AN). Data suggest common central pathways between hyperactivity and anorexia. Maintaining adapted physical activity (APA) during refeeding in AN is controversial. Many studies suggest beneficits of APA in AN on body composition (increase fat free mass and better distribution of fat mass), mood regulation, bone metabolism. We recently reported benefits of maintaining physical activity during refeeding in a mice model of anorexia (activity-based anorexia model). These benefits involved the tryptophan-kynurenin pathway. Thus, we aim in the APANOR study to assess effects of APA during refeeding in AN on kynurenin metabolism.
