High Salt Intake Augments Blood Pressure Responses During Submaximal Aerobic Exercise.

ABSTRACT: Background High sodium (Na⁺) intake is a widespread cardiovascular disease risk factor. High Na⁺ intake impairs endothelial function and exaggerates sympathetic reflexes, which may augment exercising blood pressure (BP) responses. Therefore, this study examined the influence of high dietary Na⁺ on BP responses during submaximal aerobic exercise. Methods and Results Twenty adults (8F/12M, age=24±4 years; body mass index 23.0±0.6 kg·m^-2; VO₂peak=39.7±9.8 mL·min^-1·kg^-1; systolic BP=111±10 mm Hg; diastolic BP=64±8 mm Hg) participated in this randomized, double-blind, placebo-controlled crossover study. Total Na⁺ intake was manipulated via ingestion of capsules containing either a placebo (dextrose) or table
