Bland–Altman Plots comparing the differences between measured and estimated $\stackrel{.}{\mathrm{V}}$O_2max obtained from PBF model^BC (A), PBF model^HR0 (B), PBF model^{∆HR3 − HR4} (C), BMI model^BC (D), BMI model^HR0 (E), BMI model^{∆HR3 − HR4} (F) in the entire sample (n = 205). The mean differences and 95% limits of agreement are shown as solid lines and dashed lines, respectively.
