Reference values for peak oxygen uptake: cross-sectional analysis of cycle ergometry-based cardiopulmonary exercise tests of 10 090 adult German volunteers from the Prevention First Registry

01 March 2018
A recent study presented new reference values for peak oxygen uptake for cycle ergometry-based cardiopulmonary exercise test. The goal of the present analysis was to generate sex-specific and age-specific reference values for cycle ergometry-based V̇ O2peak, based on a sample of more than 10000 participants from primary preventive healthcare ch...

New Reference Values for Cardiopulmonary Exercise Testing in Children

26 January 2018
A new study on Medicine & Science in Sports & Exercise (MSSE) Journal provides updated reference values for CPET that are independent of sex and body size. Cardiopulmonary exercise testing (CPET) is an essential tool to assess cardiorespiratory fitness (CRF) in children. There is a paucity of adequate pediatric reference values that are...

Deficit of Fat Free Mass in Very Preterm Infants at Discharge is Associated with Neurological Impairment at Age 2 Years

26 January 2018
A new key paper on the Journal of Pediatrics focuses on the importance of body composition measurement in preterm infants in order to assess neurological outcome at 2 years of age. Monitoring not only weight gain but the quality of growth during hospitalization along with assessment of body composition has become more common among neonatologist...

The Maximal Oxygen Uptake Verification Phase: a Light at the End of the Tunnel?

26 January 2018
The verification phase of the VO2max assessment has been investigated in this paper published on the Sports Medicine - Open Journal. Commonly performed during an incremental test to exhaustion, maximal oxygen uptake (V̇O2max) assessment has become a recurring practice in clinical and experimental settings. To validate the test, several criteria...

A practical clinical approach to utilize cardiopulmonary exercise testing in the evaluation and management of coronary artery disease: a primer for cardiologists

19 December 2017
A new review on the Current Opinion on Cardiiology Journal addresses the clinical approach to utilize CPET in the evaluation and management of coronary artery disease (CAD). There is growing clinical interest for the use of cardiopulmonary exercise testing (CPET) to evaluate patients with or suspected coronary artery disease (CAD). With mountin...

Recommendations for a Standardized Pulmonary Function Report. An Official American Thoracic Society Technical Statement

13 December 2017
The American Thoracic Society committee on Proficiency Standards for Pulmonary Function Laboratories has recognized the need for a standardized reporting format for pulmonary function tests. Although prior documents have offered guidance on the reporting of test data, there is considerable variability in how these results are presented to end u...

Repeatability and Meaningful Change of CPET Parameters in Normal Subjects

06 December 2017
A new study on Medicine & Science in Sports & Exercise (MSSE) Journal investigates the repeatability of CPET parameters in normal healthy subjects. Cardiopulmonary exercise testing (CPET) has many important clinical and research applications. Defining repeatability of CPET measurements is important when determining a response to a thera...

Body composition at birth and its relationship with neonatal anthropometric ratios: the newborn body composition study of the INTERGROWTH-21st project

19 October 2017
A new study on Pediatric Research Journal focuses on body composition at birth and its relationship with neonatal anthropometric ratios. This study objective is to describe newborn body composition and identify which anthropometric ratio (weight/length; BMI; or ponderal index, PI) best predicts fat mass (FM) and fat-free mass (FFM). The availa...

Open-circuit respirometry: a historical review of portable gas analysis systems

13 October 2017
The European Journal of Applied Physiology is publishing a series of reviews examining some historical insights into the measurement of whole body metabolic rate. This review is focusing on portable research based devices designed to estimate metabolic rates during typically steady-state conditions, and areas that contribute to measurement erro...
