Correlations between A peak oxygen uptake (V˙O2peak; <i>y = 0</i>.<i>81x + 0</i>.<i>51</i>, <i>r</i> = 0.81, <i>p</i>≤0.001), C peak heart rate (HR_peak; <i>y = 0</i>.<i>96x + 6</i>.<i>23; r</i> = 0.95, <i>p</i>≤0.001) and E peak power output (PPO; <i>y = 0</i>.<i>84x - 4</i>.<i>55; r</i> = 0.89, <i>p</i>≤0.001), and Bland-Altman plots of the absolute differences between BV˙O2peak, D HR_peak and F PPO determined during maximal incremental test with short (S_Test) and long (L_Test) time duration.

<p>In <b>A</b>, <b>C</b> and <b>E,</b> the dotted line represents the line of identity. In <b>B</b>, <b>D</b> and <b>F,</b> the light dotted line represents the bias from the mean difference, and the dark dotted line represents the upper and lower 95% limits of agreement.
