    The interplay between bicarbonate kinetics and gastrointestinal upset on ergogenic potential after sodium bicarbonate intake: a randomized double-blind placebo-controlled trial

  • Popis výsledku v původním jazyce

    This double-blind placebo-controlled cross-over study utilized comprehensive monitoring of blood bicarbonate (HCO3-) kinetics and evaluation of gastrointestinal (GI) upset to determine their impact on an ergogenic potential of sodium bicarbonate (SB) co-ingested with carbohydrate (CHO). Nineteen CrossFit athletes performed 6 bouts of 15 s Wingate Anaerobic Test (WAnT) 90 min post-ingestion of 0.4 g.kg-1 body mass (BM) of SB (SB+CHO treatment) or PLA (PLA+CHO treatment) with 15 g CHO. Blood HCO3- concentration was evaluated at baseline, 30-, 60-, 75- and 90 min post-ingestion, in between WAnT bouts, and 3 and 45 min post-exercise, while GI upset at 120 min after protocol started. Control (no supplementation; CTRL) procedures were also performed. An efective elevation of extra-cellular bufering capacity was observed 60-90 min post-ingestion of SB+CHO. At mean peakblood HCO3-, or at start of exercise an increase&gt; 6 mmol.L-1 in HCO3- was noted in 84% and 52.6% participants, respectively. SB+CHO did not prevent performance decrements in WAnT bouts. There were no signifcant relationships between changes in blood HCO3- and WAnTs&apos; performance. Total GI was signifcantly higher in SB+CHO compared to CTRL, and stomach problems in SB+CHO compared to CTRL and PLA+CHO. There were inverse associations between peak- (p = 0.031; r = - 0.495), average- (p = 0.002; r = - 0.674) and minimum power (p = 0.008; r = - 0.585) and total GI upset, as well as average power and severe GI distress (p= 0.042; r = - 0.471) at SB+CHO. The implemented dose of SB+CHO was efective in improving bufering capacity, but did not prevent decrements in WAnTs&apos; performance. GI side efects were crucial in afecting the ergogenic potential of SB and thus must be insightfully monitored in future studies.
