The evidence that cardiorespiratory fitness (CRF) predicts morbidity and mortality independent of commonly obtained risk factors isbeyond dispute.   Observations establishing that the addition of CRF to algorithms for estimating cardiovascular disease risk reinforcesthe clinical utility of CRF.   Evidence suggesting that non-exercise estimations of CRF are associated with all-cause mortality...

Is exercise capacity reduced more than 3 months after SARS-CoV-2 infection among those with long COVID-19 (LC) symptoms compared with recovered individuals without symptoms, and what patterns of limitations on cardiopulmonary exercise testing (CPET) are common? In this systematic review and meta-analysis of 38 studies comprising 2160 participants, exercise capacity was reduced by 4.9 mL/kg/min...

Although the marathon race has been democratized, it remains complex due to the famous “hitting the wall” phenomenon after the 25th km. To characterize this “wall” from a physiological and Rate of Perceived Exertion (RPE) perspective in recreational marathon runners, we report first continuous breath-by-breath gas exchange measurements during an actual marathon race. In order to test...

University of Nebraska at Omaha - Department of Biomechanics - relied on COSMED K5 to measure the metabolic cost of walking with a robotic waist tether. The metabolic rate during walking can be minimized by providing assistance at the waist of individuals undergoing physical therapy. By focusing on the center of mass of an individual, the waist, Antonellis et al. developed a robotic tether...
