Rectal temperature (Tre), mean skin temperature (Tsk), metabolic rate (VO2), Gagge (TS) and heated thermal sensation (HTS). Upon completion of the rehydration period, there was no significant difference

between conditions for Tre and Tsk. Expectedly, metabolic rate was Cytoskeletal Signaling inhibitor different between conditions after rehydration. An average the VO2 of 4.9 ± 1.1 ml/kg/min observed in the glucose electrolyte containing beverage and the average VO2 4.3 ± 1.2 ml/kg/min observed in the non-glucose electrolyte containing click here beverage (p = 0.007). In addition, blood glucose levels in GLU condition statistically greater compared to NON-GLU fluid replacement drink were (p = 0.000). However, in both thermal scales, there is no significantly different between two conditions. Following the recovery period, there was no significant difference between the two conditions on Tre, Tsk, and both thermal scale. However, oxygen consumption

was significantly higher in GLU condition compared to NON-GLU condition. Furthermore, blood glucose level remained higher in GLU condition compare to NON-GLU condition (p = 0.009). The change in POMS TMD demonstrated no main effect for condition (p = 0.554), Tenoxicam time (p = 0.273), and time by condition interaction (p = 0.053). Analyses of paired sample t-test showed that POMS TMD was decreased compared to before rehydration. However, did not differ between conditions (GLU vs. NON-GLU) (Figure 2). Figure 2 Delta POMS-SF total score with higher scores indicative of greater mood-related symptoms and thus poorer mood. Discussion The purpose of this study was to quantify changes in mood state during and following intake of fluid in hot ambient condition. The results of this study elucidate the need for fluid during exercise in the heat; however, the fluid does not need to contain high glucose or calories to maintain homeostasis. With the amount of calories that individuals consumes daily, and the amount of ergogenic aids marketed for post-exercise rehydration the data presented is noteworthy. For the most part, investigators believe a high caloric type of beverage is the optimal hydration beverage during prolonged exercise in the heat and the subsequent recovery process.
