Abstract

The aim of this study was to evaluate the influence of sodium bicarbonate (SB) supplementation on physical performance, neuromuscular and metabolic responses during CrossFit® exercise. Seventeen Advanced CrossFit®-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® 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® benchmark Fran performance, but not subsequent 500-m rowing. These data suggest that SB might be an interesting supplementation strategy for CrossFit® athletes.

碳酸氢钠能提高 CrossFit® Benchmark Fran 的成绩，但不能提高随后的 500 米划船成绩。

本研究旨在评估在 CrossFit® 运动中补充碳酸氢钠（SB）对身体表现、神经肌肉和新陈代谢反应的影响。17 名接受过高级 CrossFit® 训练的运动员完成了随机、双盲、安慰剂对照交叉方案，该方案包括四次访问，其中两次为熟悉训练，两次为实验，中间有 7 天的冲洗期。参与者在进行 CrossFit® 基准 Fran 训练和 500 米划船前 120 分钟补充 0.3 克/千克体重（BM）的 SB 或安慰剂。与 PLA（291.2 ± 71.1 秒 vs. 303.3 ± 77.8 秒，p = 0.047）相比，SB 可缩短完成 Fran 的时间，但不能缩短 500 米划船的时间（112.1 秒 ± 7.9 秒 vs. 113.2 秒 ± 8.9 秒，p = 0.26）。在试验过程中，没有发现明显的副作用。这项研究表明，SB 能提高 CrossFit® 基准 Fran 的成绩，但不能提高随后的 500 米划船成绩。这些数据表明，对于 CrossFit® 运动员来说，SB 可能是一种有趣的补充策略。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
