Effects Of Fluid Consumption Volumes On Fluid Retention During Sodium-Aided Hyperhydration Protocols, Shelby L. Greene, Elizaveta Roslanova, David M. Morris

International Journal of Exercise Science: Conference Proceedings

Numerous investigations have supported the use of sodium-aided hyperhydration to improve hydration status and exercise performance in the heat. Sodium-aided hyperhydration studies typically utilize fluid volumes ranging from 10 - 25 mL ∙ kg bm^-1; however, optimum fluid consumption volumes have not been identified. While it may seem logical that larger fluid consumption volumes would promote greater hyperhydration, excessive expansion of plasma volume could stimulate high-pressure baroreceptors and promote excessive diuresis. PURPOSE: To compare the effects of different fluid consumption volumes on fluid retention during a sodium-aided hyperhydration protocol. METHODS: Urine excretion was measured during four …
