Peak exercise response to endurance training. Comparison of maximal oxygen uptake and components in the subjects in the work by Hartley et al.²¹ with these data in patients on hemodialysis with a normal hematocrit. The first column in each category is normal subjects’ pretraining data, which are assigned 100%. The second column is the change from initial values in normal subjects post-training. The third column is the initial data from the patients on hemodialysis as percentages of those in the work by Hartley et al.²¹ The fourth column is the data from patients on hemodialysis post-training. aO₂, arterial oxygen content; a-vO₂, arteriovenous oxygen difference; Qc, cardiac output; TDC, tissue diffusing capacity.
