<scp>¹⁵N</scp>‐labeled dietary nitrate supplementation increases human skeletal muscle nitrate concentration and improves muscle torque production

Abstract

This study shows, for the first time, that skeletal muscle rapidly takes up dietary NO₃ ^- , the elevated muscle [NO₃ ^- ] following NO₃ ^- ingestion declines during exercise, and muscle NO₃ ^- dynamics are associated with enhanced torque production during maximal intermittent muscle contractions.
