Sex-dependent responses to acute sodium bicarbonate different dose treatment: A randomized double-blind crossover study

Abstract

This study quantified blood bicarbonate (HCO3-) kinetics and gastrointestinal upset to determine the gender-related ergogenic potential of sodium bicarbonate (0.15-, 0.25- and 0.35 gSB.kgFat-free mass (FFM)-1) in high intensity functional training.DesignDouble-blind randomized placebo-controlled crossover.ConclusionsThere were dose- and gender-related differences in extracellular buffering capacity and ergogenic potential of sodium bicarbonate. The study suggested a detrimental impact of gastrointestinal upset on performance.
