Comparison of heart rate monitoring combined with indirect calorimetry and the doubly labelled water (2H2 18O) method for the measurement of energy expenditure in children (original) (raw)

Summary

The aim of the present study was to compare data on 24-h energy expenditure (EE24 h) in nine boys and ten girls (mean age 9.3 and 8.1 years, respectively) by heart rates (f c) 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_f_ c and oxygen uptake measured during sleep (in the calorimeter), standing and walking on a treadmill. An estimation of energy expenditure based on 24-h_f_ c, monitoring (EE_f_ c) was made during the stay in the calorimeter and on a normal school-day. Mean results showed an overestimation in EE f_c compared to EE_cal and EE_dlw_ 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_f_ c method overestimates EE24 h by about 10%.
