A meta-analysis of scientific studies has been published on the prestigious Pediatrics Journal showing the importance of body composition monitoring in preterm infants. The study is a meta-analysis of studies published to date presenting body composition results in preterm infants at term equivalent age (TEA), which is the age at which they wou...

A new study shows for the first time the ventilatory response to exercise in COPD patients with emphysema. Sixteen patients with moderate to severe emphysema, quantified by high resolution computed tomography scan (HRCT), were studied. All participants underwent a full lung function evaluation with Quark PFT, including spirometry, diffusing cap...

A new study published on Pediatric Exercixse Medicine uses the BOD POD as the practical reference standard for body fat measurement in young male athletes. The purpose of this study was to examine the intermethods agreement of DXA and BIA with ADP to assess the %BF in young male athletes, such as swimmers, footballers, and cyclists. Air Displa...

A study by the Swedish Karolinska Instituet has been published on Clinical Nutrition Journal showing excellent results for Quark RMR in measuring indirect calorimetry in mechanically ventilated patients.  The study objectives were focused on the necessity of validating new instruments for indirect calorimetry in mechanically ventilated patients...

A new study has been published to evaluate selected factors influencing resting energy expenditure (REE) in obese female subjects. The study, published on the June issue of the World Journal of Experimental Medicine, was carried out by the Department of Experimental Medicine, Medical Physiopathology, Food Science and Endocrinology Section, Food...

A validation study has been published on Obesity Journal showing the accuracy and reliability of the newly introduced Pediatric Option Accessory for measuring body fat % in 2-6 years old with the Bod Pod GS. The objective of this study was to determine the accuracy, precision, bias, and reliability of percent fat (%fat) determined by air-displa...

A validation study has been published on Obesity Journal showing the accuracy and reliability of the newly introduced Pediatric Option Accessory for measuring body fat % in 2-6 years old with the Bod Pod GS. The aim of the research, conducted by the Mangiagalli Clinic in Milan (Italy), was to evaluate the accuracy and reliability of air-displac...

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 study was presented during 2012 ATS validating the Rint measurements obtained with Rocc Pony FX option. The study, by the University of Florence (Italy) together with the University of Herston (QLD, Australia), aimed to establish whether the Rint measurements obtained with the Pony spirometry device are similar to those obtained with Microrin...

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 pa...

A study with Quark b2 examines the impact of head-to-head competition on performance, pacing strategy and bioenergetics during a 2000-m cycling task. The study, by the University of Portsmouth together with the Deutsche Sporthochschule, aims to describe the bioenergetic basis for any changes in performance or pacing profile due to simulated hea...

A new study using K4b2 shows the impact on training and performance of asimmetry in legs muscle desaturation in short-track speed skating.
