The Claim
β-alanine supplementation has no significant effect on exercise performance lasting less than 60 seconds, based on pooled data from 14 short-duration tests showing no statistically significant difference between supplementation and placebo groups (P = 0.312).
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.
Taking β-alanine supplements does not change performance in short bursts of exercise under 60 seconds, according to combined results from 14 studies comparing supplement and placebo groups.
See the scientific wording
β-alanine supplementation has no significant effect on exercise lasting less than 60 seconds, as demonstrated by pooled data from 14 short-duration tests showing no difference between supplementation and placebo groups (P = 0.312).
β-alanine builds up a molecule in muscles that soaks up acid produced during intense effort. This acid slows down muscle function, so soaking it up lets muscles keep working harder for longer. But in very short bursts, not enough acid builds up for this molecule to matter, so the supplement does nothing.
What the research says
1 studyStudy: Effects of β-alanine supplementation on exercise performance: a meta-analysis
Taking β-alanine doesn’t help you sprint faster for less than a minute, because your muscles don’t get acidic enough during such short bursts for β-alanine to make a difference. The study found no improvement in these quick efforts, just like the claim says.
