OBJECTIVE: Our aim is to investigate the links between duration and intensity of
exercise and the nutritional status in terms of body composition in acute
anorexia nervosa (AN) patients.
METHOD: One hundred ninety-one hospitalized women suffering from AN were
included. Exercise duration and intensity were assessed using a semistructured
questionnaire. Body composition was measured using bioelectrical impedance.
Linear multiple regression analyses were carried out using body mass index,
fat-free mass index, and fat mass index as dependent variables and including
systematically exercise duration, exercise intensity, and other confounding
variables described in the literature that were significantly associated with
each dependent variable in univariate analysis.
RESULTS: A lower BMI was linked to lower exercise intensity, AN restrictive
type, and presence of amenorrhea. A lower FFMI was linked to lower exercise
intensity, older age, AN restrictive type, and premenarchal AN. Duration of
exercise was not linked to the nutritional status.
CONCLUSIONS: Exercising at higher intensity in AN is associated with a better
nutritional status, thus, a better resistance to starvation. The impact of
therapeutic physical activity sessions, adapted in terms of exercise intensity
and patient’s clinical status, should be evaluated during nutrition
