Discussion
The aim of this study was to examine the effects of oral and topical NaHCOYo-Yo IR2 performance improved by 21% for SB-ORAL compared to PLA, which represented a moderate effect and is congruent with evidence from a meta-analysis [Pre-exercise changes in blood buffering capacity for SB-ORAL typically achieved the minimum ergogenic threshold (i.e. HCONo significant effects of SB-LOTION were observed for blood acid–base balance or electrolytes. The small, non-significant effect of SB-LOTION on blood lactate after the repeated sprint test (+1.01 mmol·LOne explanation could be a localized cooling sensation from menthol (~0.5%) in PR Lotion [Another novel finding from this study was the positive effect of oral but not topical NaHCOThere are methodological limitations that need to be considered when interpreting our results that should be addressed in the future. First, plasma volume changes from our study were based on indirect measures (e.g. hemoglobin and hematocrit). This approach has been used for estimating changes in plasma volume during maximal exercise [
