Ventilation, breathing reserve and ventilatory efficiency were similar between the ICU and non-ICU groups.Conclusions One-third of participants experienced V′O2 peak <80% predicted 3 months after hospital discharge for COVID-19. Dyspnoeic participants were characterised by lower exercise capacity due to obesity and lower ventilatory efficiency. Ventilation and ventilatory efficiency were similar between ICU- and non-ICU-treated participants.Oxygen uptake was reduced in one-third of participants 3 months after hospitalisation for COVID-19. The most common exercise limitation was deconditioning. Circulatory limitations to exercise were more common than ventilatory limitations. https://bit.ly/3jmVDQ6 %U //www.qdcxjkg.com/content/erj/58/2/2100996.full.pdf
