Results for plasma volume change ∆PV [%] estimated using Dill and Costill’s formula (1974) as modified by Harisson et al. (1982). Calculations were made based on HB and HCT results measured before the test and 0, 1, and 24 h after the test, performed with different hydration strategies in three consecutive tests: marginal means (LSM), standard errors (SE), and upper (UCI) and lower (LCI) confidence intervals.
