The outbreak of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has presented a global public health emergency. Although predominantly a pandemic of acute respiratory disease, corona virus infectious disease-19 (COVID-19) results in multi-organ damage that impairs cardiopulmonary function and reduces cardiorespiratory fitness. As such, cardiopulmonary exercise testing...

The cardiopulmonary exercise test (CPET) provides an objective assessment of ventilatory limitation, related to the exercise minute ventilation (VE) coupled to carbon dioxide output (VCO2); high values of VE/VCO2 slope define an exercise ventilatory inefficiency. This prospective study explores the methodology of CPET to evaluate pulmonary damage’s clinical impact in post-COVID subjects. More...

The study showed that VO2max is clearly elicited in all distances from the sprint to the marathon. A fast start and the time to reach VO2max is important in increasing VO2 kinetics and to improve exercise tolerance. The K5 portable breath-by-breath sampling system was used to measure VO2 and carry out the scientific study. Human locomotion naturally uses a variable pace running strategy, and it...

Cardiopulmonary exercise testing (CPX) is the gold standard method for assessing cardiorespiratory fitness (CRF); Although CPX prognostic value has been firmly established in cardiovascular, pulmonary, and musculoskeletal disease patients, it is less established in apparently healthy adults. This study, published by the Journal of the American College of Cardiology, aims to assess the association...
