Peripheral hemodynamic response to knee extension exercise in subjects with hypertension during liberal or restricted salt intake. A: systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) response to knee extension (KE) exercise. B: change in mean arterial pressure from baseline during KE exercise. C: femoral artery blood flow response to knee extension (KE) exercise. D: femoral artery vascular conductance response to KE exercise. Values are expressed as means ± SE for A, individual (circles) and mean (bars) data with SD are presented in B, C, and D. Data includes n = 18 (10 men/8 women). A 2 × 3 repeated-measures ANOVA (group, 2 levels: liberal vs. restricted salt group) [workload, 3 levels: KE exercise: 40, 60, 80% KE maximum (Max)] was performed to compare the hemodynamic responses. The Holm-Sidak method was used for α-adjustment and post hoc analysis. *P < 0.05, group effect. †P < 0.05, vs. 40%, both liberal and restricted salt groups. ‡P < 0.05, vs. 60%, both liberal and restricted salt.
