The inspired fraction of oxygen (FiO2) for the normobaric hypoxic condition was incorrectly reported to be 15.8 ± 0.8%. The correct FiO2 value for the NH condition is 17.9 ± 0.2% and the correct inspired pressure of oxygen (PiO2) values were 111.1 ± 1.1 vs 111.5 ± 1.0 mmHg in normobaric and hypobaric hypoxia, respectively. The authors wish to clarify and confirm that the simulated altitude was perfectly matched to the real altitude of 2250m. The error appears only in the paper. This correction has no impact on the living altitudes between the two hypoxic conditions, as PiO2 was strictly matched between conditions.

As a result, there are errors in Fig 4. Please see the updated Fig 4 here.

A. Daily values of inspired pressure of oxygen (PiO2 in mmHg) during the Live High-Train Low (LHTL) camps for the normobaric hypoxia (NH) and hypobaric hypoxia (HH) groups. B. Mean values of night oxygen pulse saturation (SpO2). Data are presented in mean ± standard error. Pre1-Pre2: measurements before the camps (1150 m, Prémanon, France); D01–D18: measurement during the camps (NH: hypoxic room in Prémanon, France; HH: Fiescheralp, Switzerland). #P<0.05, ###P<0.001 for differences between groups.
