Table 3: Differences in measured respiratory variables under two cadence conditions. bpm = breaths per minute. Pearson r-correlation values are shown P-values.
| Respiratory variables | Mean ± SE | Range | Correlation with Δ V̇O2 |
| Δ VO2 (ml O2/kg/min) | 1.7 ± 2.0 | -15.3-11.3 | na |
| Δ FiO2-FeO2 (%O2) | -0.33 ± 0.10 | -0.82-0.59 | 0.271 (P = 0.370) |
| Δ VE (L/min) | 6.9 ± 3.7 | -16.2-37.2 | 0.850 (P < 0.001) |
| Δ Respiration rate (bpm) | 7.0 ± 1.4 | 0.0-16.0 | 0.316 (P = 0.294) |
| Δ Tidal volume (L/breath) | -0.20 ± 0.06 | -0.54-0.17 | 0.655 (P = 0.015) |
