Brachial and carotid artery antegrade shear rate, retrograde shear rate, and oscillatory shear index at baseline and at the end of 60 min of hot water immersion. Values are means and 95% confidence intervals. Baseline values were compared with end of heating values within men and women using a paired t test, *P < 0.05 vs. baseline within men, #P < 0.05 vs. baseline within women. Values for each variable were compared between men and women using an unpaired t test; no differences were found at baseline and ‡P < 0.05 women vs. men at the end of heating.
