approaching significancep = 0.047
Significant (or trends approaching significance) changes across groups and group differences over time for creatinine ( p = 0.047, group p = 0.007), urea/BUN ( p = 0.048, group p = 0.004), and total protein ( p = 0.081, group p = 0.060) were further supported by ANCOVA analyses accounting for running intensity.
