OBJECTIVES: To assess sleeping metabolic rate (SMR), average daily metabolic rate (ADMR), and @entity79 ( @entity79 ) in @entity1 with @entity1278 , and to evaluate the effect of daily physical activity on @entity79 . DESIGN: We compared @entity1 with @entity1278 and controls using measurements on body composition, and energy expenditure. Relations between these measurements were investigated. SETTING: Daily living environments in The Netherlands, and body composition and energy expenditure laboratory of the Department of @entity1 Biology. SUBJECTS: Twelve adult, non-hospitalized @entity1 with @entity1278 , and sixteen adult normal weight @entity1 . INTERVENTIONS: Average daily metabolic rate was measured with the doubly labeled water method and sleeping metabolic rate in a respiration chamber. @entity79 was measured by dual energy X-ray absorptiometry, and percentage body fat was calculated combining the results from underwater weighing and deuterium dilution. RESULTS: @entity79 was significantly lower in @entity448 than in controls (0.989 +/- 0.081 vs 1.144 +/- 0.054 g/cm2). Also ADMR and SMR were reduced in @entity448 . The physical activity index (PAI = ADMR/SMR) was not significantly different from PAI in controls. In @entity448 , @entity79 was related to the PAI (R2 = 0.35, P < 0.05). Finally, stepwise multiple regression revealed that PAI together with the study groups as dummy variables could explain 69% of the variation in @entity79 . CONCLUSION: These findings show that in @entity448 @entity79 is reduced, but that nonetheless physical activity has a significant positive effect on bone density.
