Objective:Knowledge about physical fitness in women with bulimia nervosa (BN) or binge-eatingdisorder (BED) is sparse. Previous studies have measured physical activity largely through self-report, and physical fitness variables are mainly restricted to body mass index (BMI) and bone min-eral density. We expanded the current knowledge in these groups by including a wider range ofphysical fitness indicators and objective measures of physical activity, assessed the influence of ahistory of anorexia nervosa (AN), and evaluated predictive variables for physical fitness.Method:Physical activity, blood pressure, cardiorespiratory fitness (CRF), muscle strength, bodycomposition, and bone mineral density were measured in 156 women with BN or BED, with mean(SD) age 28.4 years (5.7) and BMI 25.3 (4.8) kg m22.Results:Level of physical activity was higher than normative levels, still<50% met the officialphysical activity recommendation. Fitness in women with BN were on an average comparable withrecommendations or normative levels, while women with BED had lower CRF and higher BMI,VAT, and body fat percentage. We found 10–12% with masked obesity. A history of AN did notpredict current physical fitness, still values for current body composition were lower when compar-ing those with history of AN to those with no such history.Discussion:Overall, participants with BN or BED displayed adequate physical fitness; however, ahigh number had unfavorable CRF and body composition. This finding calls for inclusion of physicalfitness in routine clinical examinations and guided physical activity and dietary recommendationsin the treatment of BN and BED.
