BACKGROUND: The present study seeks to assess the validity of the InBody 520™ device to predict RMR in apparently healthy adults relative to a metabolic cart (the standard, yet time-intensive, method for determining resting metabolic rate).
METHODS: Twenty-six apparently healthy adults participated in the study. Predicted RMR (pRMR) was calculated by the InBody 520™ and measured RMR (mRMR) was determined by 30-minute gas analysis and ventilated hood system. Of the 78 measurement trials conducted, 64 yielded acceptable measurement trials.
RESULTS: A Pearson product-moment correlation was used to determine the relationship between pRMR and mRMR (r=0.87, P<0.001). No significant difference existed between the pRMR (1650.89±295.96 kcal) and mRMR (1675.36±278.69 kcal) values (P=0.19).
CONCLUSIONS: Study findings suggest that the InBody520™ provides valid measurements of RMR in apparently healthy adults and can be an effective and efficient method for collecting data in a clinical setting.
