| Research Abstract |
The aim of this research is to assess the developmental changes of energy expenditure using the doubly labeled water (DLW) method and triaxial accelerometry. We measured daily energy expenditure in twenty one Japanese children aged 3-6 in both summer and winter from 2012 through 2014. Analysis of the data which we obtained using both methods in the summer and winter of 2012, showed that the averages of total energy expenditure per weight measured by the DLW method were between 79.0 and 84.0(kcal/kg/day). Comparing the data between summer 2012 and 2013 revealed that the average of integrated triaxial acceleration during three periods: at kindergarten, at home, and all other activities including transit, tended to decrease as the subjects grew. We also measured resting energy expenditure using a hood method. Measurements taken every three months revealed that the average resting energy expenditure per weight decreased as the subjects' age increased.
