Controversy exists as to the validity and reliability of hood and mask systems in measuring indirect calorimetry. The purpose of this study was to evaluate the accuracy and reproducibility of repeat measurements of resting energy expenditure (REE) in volunteers. Paired REE measurements were performed in 23 subjects after an overnight fast using hood and mask systems. Lean body mass was calculated from four skinfold measurements and body weight determinations. Data were normalized to body weight and lean body mass and were calculated as percent predicted REE in paired tests taken within 5 minutes on the same subject. No significant difference in mean REE was noted between hood and mask systems. Linear regression analysis showed a strong positive correlation (r = 0.91, p less than 0.001) between hood and mask measurements of REE.
关于头罩和面罩系统在间接测热法测量中的有效性和可靠性存在争议。本研究的目的是评估志愿者静息能量消耗（REE）重复测量的准确性和可重复性。在23名受试者禁食过夜后，使用头罩和面罩系统进行REE配对测量。通过四次皮褶测量和体重测定来计算瘦体重。数据按体重和瘦体重进行标准化，并计算为同一受试者在5分钟内进行的配对测试中预测REE的百分比。头罩和面罩系统之间的平均REE没有显著差异。线性回归分析表明，头罩和面罩对REE的测量之间存在强正相关（r = 0.91，p < 0.001）。
