Resumo

The aim of this study was to evaluate the influence of sodium bicarbonate (SB) supplementation on physical performance, neuromuscular and metabolic responses during CrossFit (R) exercise. Seventeen Advanced CrossFit (R)-trained athletes completed the randomized, double-blind, placebo-controlled crossover protocol consisting of four visits, including two familiarization sessions and two experimental trials separated by a 7-day washout period. Participants supplemented 0.3 g/kg body mass (BM) of SB or placebo 120-min prior to performing the CrossFit (R) benchmark Fran followed by 500 m of rowing. SB improved time to complete Fran compared to PLA (291.2 +/- 71.1 vs. 303.3 +/- 77.8 s, p = 0.047), but not 500 m rowing (112.1 s +/- 7.9 vs. 113.2 s +/- 8.9 s, p = 0.26). No substantial side-effects were reported during the trials. This study showed that SB improved CrossFit (R) benchmark Fran performance, but not subsequent 500-m rowing. These data suggest that SB might be an interesting supplementation strategy for CrossFit (R) athletes. (AU)
