  • Renal injury markers at baseline, after exercise day 1 and day 3. Data were presented as median (IQR).

  • a Significantly different from baseline.

  • b Significantly different from day 1.

  • c A nonparametric alternative was used: Friedman test for time‐effect and Wilcoxon signed‐rank test for differences between individual days.
