Effectiveness of Glycerol Ingestion for Enhanced Body Water Retention during Cold Water Immersion
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.
