The aim of the present study was to compare data on 24-h energy expenditure (EE24h) in nine boys and ten girls (mean age 9.3 and 8.1 years, respectively) by heart rates (fc) combined with energy expenditure obtained from a 1-day stay in an indirect calorimeter (EEcal) and a 2-week period of normal living using the doubly labelled water method (EEdlw). Individual calibration curves were derived from fc and oxygen uptake measured during sleep (in the calorimeter), standing and walking on a treadmill. An estimation of energy expenditure based on 24-h fc monitoring (EEfc) was made during the stay in the calorimeter and on a normal school-day. Mean results showed an overestimation in EEfc compared to EEcal and EEdlw of 10.4% and 12.3% respectively, varying from 6.3% to 16.2%. These results confirmed earlier observations in adults that for a group the fc method overestimates EE24h by about 10%.
本研究的目的是比较9名男孩和10名女孩（平均年龄分别为9.3岁和8.1岁）的24小时能量消耗（EE24h）数据，这些数据通过心率（fc）结合在间接热量计中停留1天所获得的能量消耗（EEcal）以及使用双标记水法在正常生活2周期间所获得的能量消耗（EEdlw）得出。个体校准曲线源自睡眠期间（在热量计中）、站立以及在跑步机上行走时测量的fc和氧气摄取量。在热量计停留期间以及正常上学日，基于24小时fc监测（EEfc）对能量消耗进行了估计。平均结果显示，与EEcal和EEdlw相比，EEfc分别高估了10.4%和12.3%，范围在6.3%至16.2%之间。这些结果证实了早期在成年人中的观察结果，即对于一组人群，fc方法高估EE24h约10%。
