Abstract

Purpose Previous studies have shown that induced metabolic alkalosis, via sodium bicarbonate (NaHCO3) ingestion, can improve short-term, repeated-sprint ability. The purpose of this study was to assess the effects of NaHCO3 ingestion on a prolonged, intermittent-sprint test (IST). Methods Seven female team-sport athletes (mean +/- SD: age = 19 +/- 1 yr, VO2peak = 45.3 +/- 3.1 mL x kg(-1) x min(-1)) volunteered for the study, which had received ethics clearance. The athletes ingested two doses of either 0.2 g x kg(-1) of NaHCO3 or 0.138 g x kg(-1) of NaCl (placebo), in a double-blind, random, counterbalanced order, 90 and 20 min before performing the IST on a cycle ergometer (two 36-min "halves" of repeated approximately 2-min blocks: all-out 4-s sprint, 100 s of active recovery at 35% VO2peak, and 20 s of rest). Capillary blood samples were drawn from the ear lobe before ingestion, and before, during, and after each half of the IST. VO2 was also recorded at regular intervals throughout the IST. Results Resting plasma bicarbonate concentration ([HCO3-]) averaged 22.6 +/- 0.9 mmol x L(-1), and at 90 min post-ingestion was 21.4 +/- 1.5 and 28.9 +/- 2.8 mmol x L-1 for the placebo and NaHCO3 conditions, respectively (P Conclusions The results of this study suggest that NaHCO3 ingestion can improve intermittent-sprint performance and may be a useful supplement for team-sport athletes.

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.
