Total Energy Expenditure, Energy Intake, and Body Composition in Endurance Athletes Across the Training Season: A Systematic Review

16 March 2017
An interesting article on Sport Medicine Online reviewed 321 scientific articles to analyze the alterations of total energy expenditure (TEE), energy intake, and body composition during different seasonal training phases. The purpose of this study was to (1) systematically analyze TEE, energy intake, and body composition in highly trained athle...

Energy Expenditure in the Immediate Postpartum Period: Indirect Calorimetry Versus Predictive Equations

14 March 2017
A new study on the Nutrition Journal analyzes the accuracy of predictive equations to estimate energy expenditure in postpartum women. The study aimed to evaluate the resting energy expenditure (REE) of postpartum women by indirect calorimetry (IC) and provide the most appropriate predictive equations to estimate it. REE of 79 women in a matern...

The correlation of respiratory muscle strength and cough capacity in stroke patients

14 March 2017
A study on the Journal of Physical Therapy Science investigates how inspiratory and expiratory training can improve cough capacity in stroke patients, which can reduce pulmonary complications. The purpose of this study was to investigate the correlation between respiratory muscle strength improvement through respiratory training and cough capac...

CORP: Measurement of the Maximum Oxygen Uptake (VO2max): VO2peak is no longer acceptable

10 March 2017
A new paper on the Journal of Applied Physiology examines the so-called secondary criteria used to validate VO2max iin particular with exercise naïve, unmotivated and/or clinical populations. This article is part of the new Cores of Reproducibility in Physiology (CORP), an American Physiology Society(APS)-wide initiative responsive to a growing...

The physiological basis and clinical significance of lung volume measurements

17 February 2017
A useful scientific review has been published in the Multidisciplinary Respiratory Medicine Journal describing how different physiological/pathological conditions can affect static lung volumes measurement. This review intends to update the reader with the physiological basis, clinical significance and interpretative approaches of the standard ...

Resting energy expenditure in the risk assessment of anticancer treatments

17 February 2017
This study, published in the Clinical Nutrition Journal, tries to show how abnormal basal energy metabolism can be associated with higher risk in anticancer treatments (like chemotherapy). Alterations of nutritional and performance status (PS) are associated with higher risk of chemotherapy toxicity. Increased resting energy expenditure (REE) i...

Body Composition Trajectories From Infancy to Preschool in Children Born Premature Versus Full-Term

10 February 2017
The Journal of Pediatric Gastroenterology and Nutrition hosts a study analyzing the body composition trajectories from birth to preschool age. The aim of the study was to longitudinally characterize infancy to preschool body composition trajectories and the association of early fat and fat-free mass gains with preschool age body composition in ...

Harris-Benedict Equation and Resting Energy Expenditure Estimates in Critically Ill Ventilator Patients

09 February 2017
A new study on the American Journal of Critical Care demonstrates the limited reliability of the Harris Benedict Equation as a substitute to indirect calorimetry in critically ill patients undergoing mechanical ventilation. This observational transversal study (sample comprised 205 patients) compared REEIC (measured with indirect calorimetry) w...

Pediatric Exercise Testing: Value and Implications of Peak Oxygen Uptake

30 January 2017
A new essay published on Children Jornal highlights the clinical relevance of cardiopulmonary exercise testing. Much of what is known about exercise physiology has been derived from studies done in adults, yet every pediatrician knows that lessons learned from research in adults do not necessarily apply to children or even to adolescents. There...

Caloric Requirements of Patients With Brain Impairment and Cerebral Palsy Who Are Dependent on Chronic Ventilation

20 January 2017
A new study on the Journal of Parenteral and Enteral Nutrition has been published showing the importance of indirect calorimetry measurements to accurately indicate the true caloric requirements of patients suffering from severe brain damage and requiring mechanical ventilation. The purpose of this present study was to determine the true calori...

Cardiopulmonary exercise testing is a better outcome predictor than exercise echocardiography in asymptomatic aortic stenosis

20 January 2017
The International Journal of Cardiology hosts a paper confirming the validity of Cardiopulmonary Exercise Testing on patients with asymptomatic aortic stenosis. The assessment of maximal aerobic capacity using peak oxygen consumption (peak VO2) can be helpful in the management of patients with asymptomatic aortic stenosis (AS). This study explo...

2017 ERS/ATS standards for single-breath carbon monoxide uptake in the lung

20 January 2017
ATS/ERS published on the European Respiratory Journal an update to the 2005 technical standards for single-breath carbon monoxide uptake in the lung. A joint taskforce appointed by the ERS and ATS reviewed the recent literature on the measurement of DLCO and surveyed the current technical capabilities of instrumentation being manufactured aroun...

Within and between-day reliability of energetic cost measures during treadmill walking

29 December 2016
This study published in Cogent Engineering Journal analyses the capacity of COSMED K4b2 portable metabolic system in detecting small physiologic changes within a day on healthy adults.
