title: Acceptability and effect of carbohydrate-electrolyte solutions on electrolyte homeostasis during field training.
abstract: Two lemon-lime flavored 2.5% carbohydrate-electrolyte solutions (CE1 supplemented with Na+, K+, and Mg+; and CE2 supplemented with NA+) were compared to plain water (water) and lemon-lime flavored water placebo (placebo) to evaluate their acceptability and consumption during 8 days of field training in hot weather. Acceptability ratings and consumption of CE2 and the flavored water placebo were similar and greater, respectively, than those for CE1. Average Na+ and K+ intakes, and serum electrolytes levels, were not affected during the 8-day trial. If food intake is adequate, consumption of carbohydrate-electrolyte solutions is apparently unnecessary to maintain electrolyte homeostasis.
