目的：通过客观量化肥胖女性的无监督运动能量消耗 (ExEE) 来衡量对特定运动处方（每周 1500 kcal(-1)）的遵守情况。设计：为期 16 周的生活方式干预包括与研究人员每周举行会议，促进增加 ExEE（每周 1500 kcal(-1)）和减少饮食摄入量（每天 -500 kcal(-1)）。参与者：29 名肥胖女性分析中包括来自医院生活方式干预的体重指数 36.8 +/- 5.0 kg m(-2)，体脂 49.6 +/- 3.7%。测量：使用心率监测仪每周估计和监测 ExEE，并通过双能 X 射线吸收测量法测量干预前后的身体成分。结果：自由生活对运动处方的遵守情况各不相同，平均而言，遵守程度适中，达到 14%每周1500大卡(-1)，平均每周ExEE(每周768大卡(-1))占处方总量的51.2%。 ExEE 与体重变化相关（r = 0.65，P
Objective: To measure adherence to a specific exercise prescription (1500 kcal week(-1)) by objectively quantifying unsupervised exercise energy expenditure (ExEE) in obese women.Design: The 16-week lifestyle intervention consisted of weekly meetings with research staff and promotion of increased ExEE (1500 kcal week(-1)) and a decreased dietary intake (-500 kcal day(-1)).Participants: Twenty-nine obese females (body mass index 36.8 +/- 5.0 kg m(-2), body fat 49.6 +/- 3.7%) from a hospital-based lifestyle intervention were included in the analysis.Measurements: ExEE was estimated and monitored weekly using heart rate monitoring, and body composition was measured before and after the intervention by dual-energy X-ray absorptiometry.Results: Free-living adherence to the exercise prescription was variable and, on average, modest such that 14% achieved 1500 kcal week(-1), and the average weekly ExEE (768 kcal week(-1)) represented 51.2% of the total amount prescribed. ExEE was correlated with changes in body weight (r = 0.65, P
