dc.description.abstractThe purpose of this study was to determine the effects of glycerol induced hyperhydration on cardiovascular functions and endurance performance in athletes during the course of 90 minutes treadmill run at 30°C. In a randomized, double-blind cross over experimental design 9 male elite long distance runners were tested three times with 3 days intervals (wash out) following ingestion of 20 ml.kg-1BW of three different mixture of solutions: 1) water with 1.2 gr.kg -1 BW glycerol (G) 2) diluted sports drink (SD) and 3) aspartame flavored distilled water (W). Exercise trials were conducted at an exercise intensity of 65% maximal oxygen consumption (VO 2max) for 90 min at 30±1,8°C and 25-35% relative humidity. Blood parameters (Na +, K + and Cl' concentrations, blood and plasma volumes, plasma osmolality), VO 2, VCO 2, respiratory exchange ratio (RER), heart rate (HR), perceived rate of exertion (RPE), perceived thirst levels (PTL) and abdominal discomfort (AD) were measured pre and post fluid ingestion, at the 30th, 60th and 90th min of exercise trials. Data were analyzed using two-way (treatment × time) analyses of variance (ANOVA). Significance was defined as p<0.05. There was no significant difference in blood parameters, VO 2, VCO 2, RER, HR, RPE, PTL or AD among the three trails (p>0.05). The findings of this study showed that glycerol supplementation in elite endurance athletes has no advantages effect on cardiovascular functions or improving endurance performance during 90min of treadmill run with an intensity of VO 2max% 65 performed at 30°. © IDOSI Publications, 2011.en_US
