Fig. 1From: What is real change in submaximal cardiorespiratory fitness in older adults? Retrospective analysis of a clinical trialBland–Altman plots representing the comparisons between baseline and 6 weeks for \(\dot{V}{\text{O}}_{2}\) (ml/kg/min) and \(\dot{V}{\text{O}}_{2}\) (L/min) at different workloads and when RER (respiratory exchange ratio) reached 1.00. The black horizontal line in each plot represents the mean difference between the two timepoints, with the upper and lower representing the limits of agreement (1 standard deviation)Back to article page
