Data are presented as mean ± standard deviation. MAP, mean arterial pressure; mmHg, millimeters of mercury; s, seconds. The p-value represents the analysis of variance. Symbols indicate significant pairwise differences from Tukey post-hoc analysis:

^*p ≤ 0.025 for young vs. older adults

^{^}p ≤ 0.025 for young vs. middle-aged adults

^#p ≤ 0.025 for middle-aged vs. older adults.
