Abstract:
|
One of the primary areas in human energy metabolism research is to explore organ specific metabolic rates under resting condition. The whole-body resting energy expenditure (REE) is totality of organs/tissues energy expenditures, which can be evaluated individually as product of each organ/tissue mass and its corresponding metabolic rate. Elia postulated the well-known set of rate coefficients through an empirical method and derived a multiple linear regression. We consider testing validity of Elia's coefficients. Due to the high correlation among organ/tissue masses, conventional approach is unstable and inefficient. We propose a marginal approach by considering one organ/tissue at a time, thereby bypassing the difficulties caused by the near-ill conditioned design matrix. We apply the proposed approach to a data set and discuss results and new findings for older and younger adults.
