Figure 3.

Common carotid artery blood flow (A), diameter (B), velocity (C), and total shear rate (D) at baseline and 15, 30, 45, and 60 min into hot water immersion in men (closed circles, n = 11) and women (open circles, n = 10). Values are means and 95% confidence intervals. Baseline values for each variable were compared between men and women using an unpaired t test; no differences were found. Data were analyzed using a two-way (sex × time) mixed-model analysis of variance, *P < 0.05 vs. baseline within men, #P < 0.05 vs. baseline within women.
