Figure 3.

Cardiorespiratory measurements before (PRE) and after (POST) the exercise training. Dotted lines represent mean data from the healthy control group at baseline. (A) Peak oxygen consumption (VO₂ peak). (B) Relative change in heart rate (Δ%) between rest and the ventilatory anaerobic threshold (VAT). (C) Relative change in heart rate (Δ%) between rest and the respiratory compensation point (RCP). (D) Relative change in heart rate (Δ%) between rest and peak exercise (Peak). TR C-SLE, trained patients with childhood-onset systemic lupus erythematosus; NT C-SLE, non-trained patients with childhood-onset systemic lupus erythematosus. Means with different letters are significantly different from each other: a, significant difference when compared with the healthy control group; b, no significant difference when compared with the healthy control group.
