Cardiorespiratory Fitness and Physical Activity following Lung Transplantation: A National Cohort Study

2020

<b><i>Background:</i></b> Low cardiorespiratory fitness and inactivity are common after lung transplantation (LTx). The causes of exercise intolerance are incompletely understood. <b><i>Objectives:</i></b> The aim of this study was to objectively assess cardiorespiratory fitness and physical activity, evaluate causes of exercise intolerance, and explore clinical factors associated with cardiorespiratory fitness after bilateral LTx (BLTx). <b><i>Materials and Methods:</i></b> Peak oxygen uptake (V<b>∙</b>O<sub>2peak</sub>) and exercise-limiting factors were evaluated by a treadmill cardiopulmonary…
