Effects of sodium bicarbonate ingestion on measures of wingate test performance: A meta-analysis
Open accessAbstract
The review aimed to perform a meta-analysis of studies exploring the acute effects of sodium bicarbonate on Wingate test performance. Ten databases were searched to find studies that examined the effects of sodium bicarbonate on single and repeated Wingate tests. Meta-analyses were performed using the random-effects model. Ten studies were included in the review. There was no significant difference between the sodium bicarbonate and placebo trials for mean power in Wingate test 1 (standardized mean difference [SMD] = 0.02; 95% confidence interval [CI]: -0.07, 0.11) and test 3 (SMD = 0.21; 95% CI: -0.16, 0.58). There was a significant effect of sodium bicarbonate on mean power in Wingate test 2 (SMD = 0.09; 95% CI: 0.03, 0.16), and test 4 (SMD = 0.62; 95% CI: 0.15, 1.08). When considering studies that used shorter rest intervals between repeated Wingate tests, a significant effect of sodium bicarbonate was found on mean power in Wingate test 3 (SMD = 0.40; 95% CI: 0.01, 0.80). There was no significant difference between the sodium bicarbonate and placebo trials for peak power in Wingate test 1 (SMD = -0.01; 95% CI: -0.06, 0.04), test 2 (SMD = 0.02; 95% CI: -0.10, 0.13), or test 4 (SMD = 0.29; 95% CI: -0.13, 0.71). There was a significant effect of sodium bicarbonate on peak power in test 3 (SMD = 0.09; 95% CI: 0.00, 0.17). The results of this review suggest that sodium bicarbonate may provide an ergogenic effect on measures of repeated Wingate test performance.Key Teaching Poi…

These results suggest that sodium bicarbonate may have an ergogenic effect on repeated WACT test performance.
“Overall, these results suggest that sodium bicarbonate may have an ergogenic effect on repeated WACT test performance (Grgic, 2022).”

“This increase in blood bicarbonate is coupled with an increase in extracellular buffering, leading to a greater efflux of H out of the muscles active during exercise into the circulation (8, 9).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
