OBJECTIVE: To investigate the relationship between resting @entity7493 (REE) and body composition in @entity1555 ( @entity1555 ). DESIGN: An observational study. SETTING: University Research Centre. SUBJECTS: Nine Duchenne @entity1 (age range 6-12 y), mean relative weight 128%, agreed to undergo the investigation and all of them completed the study; INTERVENTIONS: Assessment of body composition (total body fat and skeletal muscle mass) by magnetic resonance imaging and resting @entity7493 by indirect calorimetry. MAIN OUTCOME MEASURES: Fat mass (FM; kg and percentage weight), @entity1386 ( @entity1386 ; kg and percentage weight), muscle mass (kg and percentage weight), resting @entity7493 (kJ/kg body weight and kJ/kg @entity1386 ). RESULTS: : In Duchenne @entity1 fat mass averages 32% and total skeletal muscle mass 20% of body weight. Resting @entity7493 per kg of body weight falls within the normal range for @entity1 of the same age range, while when expressed per kg of @entity1386 is significantly higher than reference values. No relationship was found between REE and total skeletal muscle mass. CONCLUSIONS: Our results do not demonstrate a low REE in @entity1555 @entity1 ; on the contrary REE per kg of @entity1386 is higher than normal, probably due to the altered @entity1386 composition. We suggest that the development of @entity28 in @entity1555 @entity1 is not primarily due to a low REE but to other causes such as a reduction in physical activity and or overfeeding.
