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 is a growing body of literature defining the state-of-the-art...

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 explores therefore the relationship between peak VO2 and...

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...
