While overexercise has long been associated with eating disorders, the use of exercise as a potential addition to treatment for eating disorders has not been fully explored. Preliminary inpatient studies featuring resistance training have shown promising results, but little is known regarding potential physiological and psychological benefits of muscle strengthening in an outpatient setting.

PURPOSE: To determine the effects of a 10-week, supervised resistance training program on bone mineral density (BMD), body composition (BC), strength, depression, and eating-disordered tendencies in community-dwelling females with anorexia nervosa (AN) or eating disorders not otherwise specified (EDNOS).

METHODS: Fourteen females (17 yrs - 35 yrs) were randomly assigned to an experimental or control group. Entry criteria for the study included a minimum body mass index (BMI) of 14 kg/m2 and a clinical diagnosis of AN or EDNOS. Percent body fat, estimated 1-repetition max (1-RM) of the chest and legs, and forearm, hip, and lumbar spine BMD were measured prior to and following the strength training intervention. Participants also completed the Beck Depression Inventory-II (BDI-II), the Eating Disorders Inventory-3 (EDI-3), and the Incorporating More Physical Activity and Calcium in Teens Food Frequency Questionnaire (IMPACT) before and after training.

RESULTS: No statistically significant group differences (p >.05) were observed in body fat percentage, BDI-II scores, EDI-3 scores, and forearm, hip, and lumbar spine BMD following the 10-wk program. However, there were clinically relevant increases in BMD of the forearm, hip, and lumbar spine in the experimental group following the intervention. In addition, there were significant increases (p < .001) in chest and leg strength of participants in the experimental group following the intervention.

CONCLUSION: These data show that community-dwelling women with eating disorders can participate in a supervised resistance training exercise program and experience positive physical and psychological results.
