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. The efficacy of assistive devices used during walking is often measured as a reduction in metabolic cost. Metabolic cost is typically assessed within a day or on multiple days, yet the benefit of performing within-day...

This new paper reviews results of previous studies in comparing cardio pulmonary exercise test results achieved by arm cycle ergometer (AC) and to leg cycle ergometer (LC) Despite most of the CPET tests are performed using a treadmill or a leg cycle ergometer, due to disability, co-morbidity, preference or athletic discipline there is a need to investigate alternatives, ie to perform the test with...

The prognostic value of CPET in Idiopathic Dilated Cardiomyopathy (iDCM) patients has been studies in a recent paper published in the International Journal of Cardiology. Although cardiopulmonary exercise testing (CPET) is considered as an important tool in risk stratification of patients with heart failure (HF), prognostic data in the specific setting of Idiopathic Dilated Cardiomyopathy (iDCM)...

A recent paper on the European Journal of Clinical Nutrition provides a conceptual historical framework for examining the evolution of energy exchange concepts and measurement methods. Energy exchange is fundamental to life and is a cornerstone in the study of human physiology, metabolism and nutrition. A global effort is underway to further our understanding of human energy exchange and its components...
