Abstract

Abstract : The efficacy of ingesting an aqueous glycerol (GLY) solution to reduce diuresis and enhance body water retention during prolonged cold water dives was tested. Six subjects were assigned to either a water treatment (WT) or glycerol treatment (GT) group. During the predive period, divers drank approximately 2 liters of flavored water solutions 30 milliliters per kilogram (ml/kg) lean body mass (LBM) with or without GLY (1.5 ml/kg LBM). Total urine output did not differ between treatments. The amount of urinary glycerol (uGLY) collected during the hyperhydration period (prehydration to 90 minutes after hydrating) and the three-hour dive periods accounted for 4.1% and 10.3%, respectively, of the total GLY ingested. Hyperhydration with GLY (1.2 ml/kg LBM) appears ineffective in significantly reducing body water loss in divers under the stress of prolonged cold water immersion.
