  • Mb, body mass; O2max, maximal O2 consumption; f, breathing frequency; VT, tidal volume; VMIN, minute volume; OEE, oxygen extraction efficiency.

    Values were statistically significant (one-tailed test) after a sequential Bonferroni correction for multiple simultaneous tests; *P<0.05; **P<0.01; ***P<0.001.
