Are oxygen uptake kinetics and chronotropic responses to exercise impaired in survivors of severe COVID-19?
Are oxygen uptake kinetics and chronotropic responses to exercise impaired in survivors of severe COVID-19?
Survivors of severe COVID-19 exhibit impaired oxygen uptake kinetics and chronotropic responses during exercise, which may explain their exertional intolerance.
Impaired kinetics may underlie exertional intolerance in severe COVID-19 survivors; hypothesis-generating, requiring longitudinal studies before clinical application.
kinetics is significantly impaired at both the onset (on-transient) and the recovery phase (off-transient) of exercise in these patients. Furthermore, our results suggest that survivors of severe COVID-19 may have a higher metabolic demand at a walking pace. These findings may partly explain the exertional intolerance frequently observed following COVID-19.
