The Claim
Four weeks of beta-alanine supplementation at 65 mg/kg/day in highly trained cyclists is associated with an 89% likelihood of increasing total work done during 30 maximal isokinetic knee extensions, with a p-value of 0.09 indicating non-statistical significance.
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.
In highly trained cyclists, taking beta-alanine at 65 mg per kilogram of body weight daily for four weeks is associated with an 89% probability of increasing total work performed during 30 maximal knee extensions, though the result did not reach statistical significance.
See the scientific wording
Four weeks of beta-alanine supplementation at 65 mg/kg/day in highly trained cyclists shows an 89% likelihood of improving total work done during 30 maximal isokinetic knee extensions, though this change was not statistically significant (p=0.09), indicating a probable but uncertain benefit for cumulative muscular output.
Beta-alanine builds up a substance in muscles that soaks up acid produced during hard exercise. This keeps the muscle environment less acidic, allowing muscle fibers to keep contracting strongly for longer without getting tired.
What the research says
1 studyThis study found that cyclists who took beta-alanine for four weeks probably did more total work during repeated knee extensions, even though the result wasn’t quite strong enough to be called definite. The trend was positive and matched what the claim says.
