Salt restriction lowers blood pressure at rest and during exercise without altering peripheral hemodynamics in hypertensive individuals. Am J Physiol Heart Circ Physiol 317: H1194–H1202, 2019. First published December 1, 2019; doi:10.1152/ajpheart.00431.2019.—In this article, the groupings in Fig. 2A were incorrectly represented and the mean arterial pressure of the liberal salt group was omitted, which is now corrected below.
Fig. 2.
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.
