Abstract	We assessed the validity of predicting peak oxygen uptake ( $$ {\dot{V}} $$ O2 peak) from the relationship between oxygen uptake ( $$ {\dot{V}} $$ O2) and overall ratings of perceived exertion (RPE) obtained during the initial stages of a cardiopulmonary exercise test (CPET).Fifteen healthy participants and 18 patients with chronic obstructive pulmonary disease (COPD) performed a maximal CPET, during which $$ {\dot{V}} $$ O2 and RPE were measured until RPE15.Individual regressions between $$ {\dot{V}} $$ O2 and RPE≤15 were extrapolated to RPE19 to predict $$ {\dot{V}} $$ O2 peak. Mean actual and predicted $$ {\dot{V}} $$ O2 peak were not significantly different in healthy women (18.9 ± 4.1 vs. 20.4 ± 4.5 mL kg−1 min−1, respectively) and men (28.9 ± 7.8 vs. 29.7 ± 8.5 mL kg−1 min−1, respectively), or in women (15.2 ± 4.7 vs. 15.8 ± 5.0 mL kg−1 min−1, respectively) and men (16.2 ± 4.4 vs. 17.4 ± 5.4 mL kg−1 min−1, respectively) with COPD (P = 0.067). Moreover, actual and predicted $$ {\dot{V}} $$ O2 peak were highly correlated in healthy participants and COPD patients (r ≥ 0.89; P < 0.001). The bias and 95 % limits of agreement were −1.0 ± 4.0 and −1.0 ± 4.6 mL kg−1 min−1 for healthy and COPD participants, respectively. $$ {\dot{V}} $$ O2 peak can be predicted with acceptable accuracy in healthy participants and patients with COPD from the individual relationship between $$ {\dot{V}} $$ O2 and RPE≤15.
