Resumen:
Background
and purpose: Exercise has not typically been used as an adjunct in treatment of anorexia nervosa (AN). This study aimed to examine the effects of progressive resistance exercise (PREx) on perceived quality of life (QoL) and body composition in adolescents with AN.
Materials and methods
Forty-four adolescents diagnosed with AN were randomly allocated to either PREx or control groups after hospitalization. The PREx group completed twenty-four PREx sessions over two months including three sets of 8–10 repetitions of eight whole-body exercises at a moderate intensity. QoL and body composition were evaluated at baseline and after two months using Health Questionnaire Short-Form 36 (SF-36) and anthropometric measurements.
Results
At completion, forty-one participants (n = 19 PREx, and n = 22 controls) with mean age of 12.78 ± 0.88 years and mean body mass index of 18 ± 2.2 kg/m2 were analyzed. Significant group x time effects were found on SF-36 role physical (RP) scores. Significant improvements with large effect sizes (d > 0.72) were found in RP, and arm circumferences in the PREx group. Spearman association analyses between percent change in anthropometric variables and change in...
