A new study using K4b2 shows the impact on training and performance of asimmetry in legs muscle desaturation in short-track speed skating. The study, by the Department of Biological Sciences of the University of Essex together with the British Olympic Medical Institute, analyses the impact of the restriction of muscle blood flow, due to the low...

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]). The...

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 c...

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 ex...

A new study examines the role of indirect calorimetry in ventilated ICU patients as an important clinical tool compared to daily estimated energy requirements predicted by the Schofield equation. Twenty four indirect calorimetry tests were conducted during routine practice using the COSMED Quark RMR. The study conclusion was that "the Schofiel...

A new validation study of K4b2 was presented during last ACSM show assessing both the validity and reliability of the system. 19 Caucasian endurance trained individuals and 30 adolescents from a rural primary school in Kenya completed maximal incremental running tests with COSMED K4b2. The Douglas bag method (DB) was used as the criterion for c...

An educational video has been published by ERS showing the procedure of performing a Cardiopulmonary Exercise Test with a COSMED metabolic cart. The tutorial shows the patient selection stage, the required equipment, preparation and set-up, how to perform the test and how to interpret the data. See the tutorial on the ERS website: click here ...

A recent study of the Italian Diabetes Exercise Study (IDES) showed how supervised exercise can produce significant improvements of cardiovascular risk among Type-2 diabetes patients. This study aimed to assess the efficacy of an intensive exercise intervention strategy in promoting physical activity and improving hemoglobin A1c (HbA1c) level a...

The COSMED Quark RMR with the ICU option has been recently assessed to be a suitable indirect calorimeter to be coupled with a mechanical ventilator in an intensive care unit setting. The study aimed at measuring the influence of the ventilatory settings on the parameters measured by the Quark RMR metabolic monitor. The energy expenditure of 10...

A validation of Fitmate PRO by the University of Tennessee was published recently in the prestigious Journal of Strength and Conditioning. The main purpose of this study was to assess the validity of the Cosmed Fitmate for the prediction of maximal oxygen consumption through a submaximal exercise testing. Fitmate predicts VO2max based upon the...

A validation study of Quark RMR by CRNHR was published on the 6th issue of the European Journal of Clinical Nutrition and Metabolism. The objectives of the study by the Centre de Recherche en Nutrition Humaine Rhône-Alpes were to validate accuracy and reliability of COSMED QUARK RMR indirect calorimeter versus the DELTATRAC II™, a well-establis...

In this study the measurements of two different indirect calorimeters from COSMED (Fitmate and Quark RMR) were correlated and analysed for better adequacy. The aim of this study was to check measurements of two indirect calorimeters on obese women and then comparing the results with predictive formulas (the popular Harris Benedict Equation). Tw...

COSMED's Fitmate has been validated against a “first principles” metabolic calibrator capable of delivering cyclic air flows of known tidal volume, frequency and gas makeup. “First principles” systems are advantageous in validation testing because their calibration is based solely on easily measured and verified quantities such as length and ti...

COSMED's Quark CPET has been validated against a “first principles” metabolic calibrator capable of delivering cyclic air flows of known tidal volume, frequency and gas makeup. “First principles” systems are advantageous in validation testing because their calibration is based solely on easily measured and verified quantities such as length and...
