The measurement of Resting Metabolic Rate using the Fitmate with a ventilated canopy hood was validated by a study presented during the 2012 ACSM Annual Meeting. The study, by the Northern Illinois University, aimed to determine the reliability and validity of measuring resting metabolic rate (RMR) with COSMED’s FitMate™ metabolic system using a canopy dilution set-up compared to a previously validated...
A French study examined the reproducibility of the Fitmate metabolic system in measuring breathing gas during a cycling exercise. The study (in French language), by the University of Nice Sophia-Antipolis, aimed to demonstrate the reproducibility of respiratory variables (VE and VO2) using a desktob metabolic system like Fitmate. Twenty-one participants performed during two sessions three 5-min...
Three isocaloric breakfasts with different levels of carbohydrate contents have been compared to assess their impact on dietary-induced thermogenesis. 16 lean young males were tested with three isocaloric breakfasts different in Glycemic Index and/or Glycemic Load (high GI and high GL vs. low GI and low GL vs. high GI and low GL [HGI-LGL]). Their Respiratory quotient and Dietary-induced Thermogenesis...
This study was undertaken to determine the impact of patients’early in-ICU energy balance on the pathogens responsible for ventilator-associated pneumonia. Energy balance (energy delivered - calculated resting energy expenditure) was compared according to the microbiologic results of the fiber-optic BAL (bronchoalveolar lavage) cultures of 76 consecutive patients receiving acute prolonged (≥ 96...
This study proves that accurate measurement of the REE in underweight anorexia nervosa patients is clinically useful, overcoming the limits of predictive formulas. Several studies showed that REE is low in underweight patients with Anorexia Nervosa, this is mainly due to the loss of lean body mass, a major determinant of REE, and to a lesser extent, to the effect of several neuroendocrine changes. The...
