In accordance with the specific aims, two a priori power analyses (JMP Pro 12) for primary physiological outcomes were conducted.To date, no significant differences in core temperature have been observed using BET in human trials. Therefore, the power analysis for core temperature was determined using a non‐ human, BET model exposing sheep to a passive heat load (43°C, 49% RH) (DiGiacomo et al., Similarly, the power calculation for change in plasma volume is based upon a BET supplementation study in a human model reporting a mean difference of 3.3% pre‐ versus post‐ 36 min of exercise (running at 65% VOAll variables were assessed using null‐hypothesis testing, with significance set at To evaluate the impact of preloaded BET supplementation on fluid balance in recreationally active men, measures of fluid compartments (i.e., ICF, ECF, TBW, and plasma osmolality), plasma electrolytes (NaTo determine the degree to which preloading with BET impacts fluid balance and heat tolerance relative to placebo in young (ages 18–45 years), recreationally active men, paired‐samples t‐test and two‐way (treatment x time) repeated measures analysis of variance (RMANOVA) were used to identify differences. Specifically, sweat rate (i.e., changes in nude body weight) and subjective measures of thirst were compared at two time‐points (min 0 and 60) using paired‐samples If sphericity was violated, a Greenhouse–Geisser correction was performed. In the case of statistical significance, a post hoc one‐way ANOVA with Bonferroni tests were used to identify significant differences.
