The correlation between the estimated and measured VO₂max. (A) Correlation between the estimated and measured VO₂max value of all participants. The thin line is the identity line of the measured and estimated VO₂max. (B) Bland-Altman plot (estimated-measured VO₂max, n = 24). The solid line represents the mean value, and the dotted line represents the 1.96 SD (95% limit of agreement). With the exception of one participant, the data was randomly distributed among the 1.96 SD range.

VO₂max = maximal oxygen consumption, SD = standard deviation
