f, breathing frequency; Vt, tidal volume; Vmin, minute volume; OEE, oxygen extraction efficiency; d.f., degrees of freedom.
Data include the entire 10-week experimental period, except for the first week. Sex was included as a fixed factor. When the sphericity condition was not met (see Materials and methods), P-values are reported with H-F corrections (both numerator and denominator d.f. were multiplied by H-F epsilon to obtain corrected d.f.).
Values in bold indicate statistical significance (α=0.05); ^{*}P<0.05; ^{***}P<0.001.
