Paired comparisons and relationships of absolute and relative \(\:\dot{\text{V}}\)O2peak and RER between cycling and CLIMIT ramp tests among high, middle, and low absolute and relative \(\:\dot{\text{V}}\)O2peak groups according to lower and upper limits of 95% confidence intervals. (A-I) Paired comparisons and relationships of absolute \(\:\dot{\text{V}}\)O2peak and RER between cycling and CLIMIT ramp tests among high, middle, and low groups. (J-R) Paired comparisons and relationships of relative \(\:\dot{\text{V}}\)O2peak and RER between cycling and CLIMIT ramp tests among high, middle, and low groups. r, correlation coefficient; CI, confidence interval; R2, coefficient of determination; RER, respiratory exchange ratio; \(\:\dot{\text{V}}\)O2peak, peak oxygen uptake. Significant difference = **P < 0.01; ****P < 0.0001.
