Strength and Power Improvements in Athlete and Non-Athletes During Intensive Eating Disorder Treatment

Understanding the unique needs of athletes who undergo eating disorder (ED) treatment is sorely needed. This study explores changes of strength and power in athlete (n = 21) and non-athlete (n = 36) patients from intake to discharge. Maximal oxygen consumption, vertical jump, push-ups, hand grip strength, and body mass index (in anorexia nervosa; AN) were measured among treatment center patients. The number of push-ups and hand grip strength were significantly improved upon discharge in the full sample (ps < .005) and in AN only (ps < .001). Body mass index was also significantly higher in AN (p < .001). Maximal oxygen consumption and vertical jump did not significantly improve between admission and discharge in either group (ps > .40). This study is the first to investigate measures of strength in athletes engaged in intensive eating disorder treatment and indicates the need to address the psychological mindset around physical activity using exercise education as part of a comprehensive program. Recommendations for incorporating exercise into an intensive ED treatment center are also provided.
