3. Fig 2
Bland-Altman plot of cardiorespiratory parameters (A) V̇o2peak, (B) V̇epeak, (C) peak heart rate, and (D) distance walked between measurements 1 and 2. The x axes show means of peak cardiorespiratory parameters and distance walked from both tests; the y axes show the differences between peak cardiorespiratory parameters and distance walked during measurements 1 and 2. Abbreviation: HRpeak, peak heart rate.
