Estimation of Warfighter Resting Metabolic Rate
Abstract
The purpose of this study was to identify the best method for estimating the resting metabolic rate (RMR, kcal/h) of the warfighter, given the current level of available knowledge, using methods and data published in the literature. Several published equations for estimating the standard resting metabolic rate (RMRS), defined as the metabolic rate in the morning after an overnight fast, with the subject at rest in a thermoneutral environment in a supine position, were also evaluated. A series of comparison data sets of individual data from results published in the literature, in which obese subjects and subjects younger than 18 and older than 55 yrs, were eliminated. A comparison between estimated RMRS and RMRS values from the comparison data set showed that equations developed by Mifflin and coworkers in 1990 fit the data the best. It was determined that once inherent differences in the subject populations used to develop and test the equations were considered, that the equations developed by differences in the subject populations used to develop and test the equations were considered, that the equations developed by Schofield (1985) for the World Health Organization, provided the best fit to the data. From linear regression analyses on the comparison data set, it was found that a combination of the estimated lean body mass (computed from weight, age and gender) and gender or the body weight (W, kg) with gender and age fit the data equally well STANDARD ERROR OF THE ESTIMATE (SEE = 6.75 kcal/h.
