Urine color, osolality and specific electrical conductance are not accurate measures of hydration status during postexercise rehydration

摘要

background. The aim of the study was to determine whether urine color, osmolality and specific electrical conductance (SEC) provide an accurate index of hydration status and of fluid requirements during the recovery phase after an acute exercise-induced dehydration. Methods. Experimental design: eight well-trained healthy males Were dehydrated about 3/100 of body mass, 3 times, by cycling in The heat.
