Effect of acute high-phosphate intake on muscle metaboreflex activation and vascular function

Increased consumption of inorganic phosphate (Pi), an abundant ingredient in processed foods, has been associated with elevated cardiovascular disease risk; however, studies investigating underlying mechanisms are limited. Recently, high dietary Pi was shown to exaggerate the pressor response to static muscle contraction in rodents in part because of overactivation of metabolically sensitive skeletal muscle afferents. Whether acute high Pi...
