The purpose of this study was to examine how inducing hyperhydration with a glycerol solution and a sodium solution prior to exercise influenced performance and hydration status during a moderate set-intensity exercise bout followed by a time-to-exhaustion bout when compared to a control solution containing water only. Six well-trained runners ages 21 to 38 with an average relative VO2 peak of 57 ml/kg/min participated in three trials. Each trial included a 2.5 hour hyperhydration phase where participants ingested a solution containing water, glycerol, or sodium. Following hyperhydration, participants ran for 90 minutes at 65% of their HRR followed by a time to exhaustion bout at 85% of their HRR. There were no significant differences in performance or changes in total body water between solutions. There was a lower relative percentage of total urine output from sodium (p=0.001) and glycerol (p
