Modified Shuttle-Run Test (MST) by random, double blind crosses over experimental design. Subjects were administered 2 different solutions at amounts 20 mLkg(-1)VA before the test. Solution 1: 1.0 gkg(-1)VA glycerol (GS) mixed with 20 ml. kg(-1)VA water. Solution 2: 20 mLkg(-1)VA saccharin flavored distilled water (WS). Measurements were performed for 3 times, before and after supplementation phase and at the end of exercise. Total Body Water, Heart Rate, Body Temperature and Urine Density were measured in the study. In conclusion; it was determined that both glycerol and water supplementations delayed the formation of dehydration: But no significant difference was observed between groups of GS and WS in terms of KAH, TVS, ID and VS values (p > 0.05). In conclusion of this study, it was observed that the glycerol supplementation administered to volleyball players have no positive effect on body hydration, heart rate and body temperature and on the improvement of sportive performance.eninfo:eu-repo/semantics/closedAccessGlycerolDehydrationSupplementationErgogenic aidArticle42765772N/AWOS:000304504700020N/A
