Table 4. Correlations between Borg Scale at Peak Exercise and Physiological Measures a,b.
| All Patients (N = 66) | MIP, cm H2O | MEP, cm H2O | VO2 at AT, mLkg-1min-1 | Peak VO2, mLkg-1min-1 | VE/VCO2, Slope | TV/RR, Slope |
|---|---|---|---|---|---|---|
| Borg scale | -0.28 c | -0.23 | -0.25 | -0.23 | 0.26 c | -0.47 c |
a Abbreviations: AT, anaerobic threshold; MEP, maximal expiratory pressure; MIP, maximal inspiratory pressure; RER, respiratory exchange ratio; RR, respiratory rate; TV, tidal volume; VCO2, carbon dioxide output; VE, minute ventilation; VO2, oxygen uptake.
b Data are Rho values in Spearman’s correlation.
c P < 0.05.
