Carbohydrate-Electrolyte Solutions during Field Training: Acceptability and Effect on Electrolyte Homeostasis

Abstract

Two 2.5% carbohydrate-electrolyte solutions (CE1 and CE2) were compared to plain water (W) and a flavored water placebo (FW) to evaluate their acceptability and consumption during field training in hot weather. Hedonic ratings and consumption of CE3, FW, and W were similar and significantly higher than CE1. FW and W groups consumed the largest amounts of test beverages. For all subjects, average sodium and potassium intakes were 4.2 + or - 0.1 g and 3.4 + or - 0.07 g, respectively, and serum levels were not physiologically different after 8 days. If food intake is adequate, consumption of water of FW is adequate to maintain electrolyte homeostasis. Keywords: Fluid intake; Carbohydrate- electrolyte solutions; Heat; Field training; Beverage acceptability; Glucose beverages; hedonic ratings; Nutrient solutions. (KT)
