${\dot{V}}_{E}$ (mL g⁻¹ min⁻¹)	2.0 ± 0.7	1.9 ± 0.4	0.6343
PIF (mL g⁻¹ s⁻¹)	1.03 ± 0.16	1.15 ± 0.13	0.1345
PEF (mL g⁻¹ s⁻¹)	1.04 ± 0.18	1.08 ± 0.29	0.7207
ETCO₂ (mmHg)	53.2 ± 3.7	50.5 ± 6.1	0.2735
$S_{p O_{2}}$ (%)	94.8 ± 2.5	94.1 ± 3.1	0.5821
Body mass (g)	24.8 ± 1.5	26.1 ± 0.8	0.0382

f _R, respiratory frequency; V _T, tidal volume; ${\dot{V}}_{E}$ , minute ventilation; PIF, peak inspiratory flow; PEF, peak expiratory flow; ETCO₂, end‐tidal carbon dioxide; $S_{p O_{2}}$ , peripheral capillary oxygen saturation. Data are shown as the mean ± SD and were statistically compared using two‐tailed unpaired Student's t tests.
