Relation between sweat chloride concentration and exercise load. (A–C) Change in sweat chloride concentration associated with: (A) the single step (100 W – 200 W; N = 12), (B) the reverse step (200 W–100 W; N = 12), and (C) the multi-step (N = 9 at 100 W, N = 12 at 125 to 200 W) trials. Data represent mean ± SD at each exercise load. (D-E) Initial sweat concentration versus change in sweat concentration associated with: (D) the single step trial (100 W – 200 W), and (E) the reverse step trial (200 W – 100 W). C100W and C200W are the concentrations at the end of 100 W and 200 W segments of the single step and reverse single step trials, respectively. (F) Concentration changes during the multi-step trials. (G) Sweat chloride concentration at 200 W for the single step and reverse step trials. (H) Sweat chloride concentration at 100 W and 200 W for single step, reverse step, and multistep trials. Data represent mean ± SD at each exercise load. *p < 0.05, **p < 0.01, ***p < 0.001.
