The Claim
Sodium bicarbonate alone, without beta-alanine, is associated with a 2.3% improvement in 200-meter swimming performance and a 2.2% improvement in 100-meter swimming performance in competitive swimmers.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Competitive swimmers who take sodium bicarbonate without beta-alanine show a 2.3% faster time in the 200-meter swim and a 2.2% faster time in the 100-meter swim.
See the scientific wording
Sodium bicarbonate alone, without beta-alanine, is associated with a 2.3% improvement in 200-meter swimming performance and a 2.2% improvement in 100-meter swimming performance in competitive swimmers, suggesting a performance benefit independent of beta-alanine.
Swimmers take sodium bicarbonate, which increases the blood's ability to neutralize acid produced by muscles during hard sprinting. This keeps the blood less acidic, so the muscles can keep working hard longer without getting tired, making the swimmer faster.
What the research says
1 studyThe study found that swimmers who took sodium bicarbonate (without beta-alanine) swam about 2% faster in short races, just like the claim says. This means sodium bicarbonate alone can help sprint swimmers go a little quicker.
