K4b2 Validity and Reliability during Fast Outdoor Running

06 February 2012
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...

ERS educational video on CPET with COSMED metabolic cart

02 December 2011
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 ...

Exercise intensity effects on diabetic patients tested with Fitmate PRO

04 November 2011
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...

Influence of Ventilatory Settings on Indirect Calorimetry in Mechanically Ventilated Patients

14 October 2011
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...

Validation of the COSMED Fitmate for prediction of maximal oxygen consumption

12 September 2011
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...

New validation of Quark RMR for indirect calorimetry measurements with canopy hood

12 May 2011
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...

Calorimetry in obese women: comparison of two different operating indirect calorimeters together with the predictive equation of Harris and Benedict

28 September 2010
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...

Validation of Fitmate versus "First Principles" Metabolic Calibrator

06 March 2009
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...
