There are some errors relating to reported alveolar–capillary membrane diffusing capacity (D_M) and pulmonary capillary blood volume (V_c) values in the original article. The authors incorrectly assumed that the manufacturer of the equipment (Jaeger MasterScreen PFT pro; CareFusion, Höchberg, Germany) used for the single-beath measurement of the pulmonary diffusing capacity to carbon monoxide (corrected for haemoglobin, D_LCOc) and nitric oxide (D_LNO) reported D_M and V_c according to the established standard equations outlined in the article (Munkholm et al., 2018; Zavorsky et al., 2017).

However, the authors have recently realised that the equipment reports D_M as D_LNO divided by a constant of 1.97 instead, which subsequently affects the V_c estimates. This necessitates changes to the Results, Discussion, Tables 2 and 3 and Figures 2 and 3. The overall conclusion of the article, that D_LNO appears to be the most reliable metric relating to alveolar–capillary reserve during both exercise and in the supine position, remains unchanged by these errors. However, at several points in the article, D_M is mentioned as an alternative with comparable reliability, and these statements are now unfounded.

Corrected text, figures and tables can be found below:

Finally, this article corrects the name of author Regitse H. Christensen, who was incorrectly listed as Regitse H. Chistensen.
