  • f, breathing frequency; VT, tidal volume; VMIN, minute volume; OEE, oxygen extraction efficiency.

    The fixed factors were sex and acclimation regime, whereas maximal O2 consumption O2max and body mass Mb were included as covariates.

    Values in bold were statistically significant after sequential Bonferroni adjustment for multiple simultaneous tests; *P<0.05; **P<0.01; ***P<0.001.
