Dietary protein requirements of older adults with sarcopenia determined by the indicator amino acid oxidation technology.

ABSTRACT:

Background

Although protein supplementation may be desirable in the management of sarcopenia, the appropriate protein requirements for older adults with sarcopenia are presently unclear.

Objective

The aim of this study was to determine the protein requirements of older adults (65-81 year) with sarcopenia by using the indicator amino acid oxidation (IAAO) technology.

Methods

Nine older adults with sarcopenia (four male participants and five female participants) participated in the study, with protein intakes ranging from 0.1 to 1.8 g/(kg·d). Each participant consumed an adapted diet with a protein level of 1.0 g/(kg·d) and 1.7 resting energy expenditure (REE) for 2 day. Day 3 was the oxidation day of the study. Diets that delivered energy at a 1.5 × REE were isocaloric
