The Claim
Twenty-eight days of beta-alanine supplementation at 800 mg four times daily significantly improves lower-body isokinetic exercise performance in female master cyclists aged 40 and older, increasing total work performed during the final third of flexion by 24.0% and average peak torque during extension by 5.4% compared to placebo.
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 female cyclists aged 40 and older, taking 800 mg of beta-alanine four times daily for 28 days increases total work done during the final third of leg flexion by 24.0% and raises average peak torque during leg extension by 5.4% compared to a placebo.
See the scientific wording
Twenty-eight days of beta-alanine supplementation at 800 mg four times daily significantly improves lower-body isokinetic exercise performance in female master cyclists aged 40 and older, increasing total work performed during the final third of flexion by 24.0% and average peak torque during extension by 5.4% compared to placebo, suggesting a targeted benefit for high-intensity, fatigue-prone muscle actions in trained older women.
Beta-alanine enters muscle cells and combines with another molecule to form carnosine, which soaks up acid produced during hard exercise. This keeps the muscle environment less acidic, allowing muscle fibers to keep contracting strongly even when tired, so more work can be done and more force can be generated in the final stages of intense effort.
What the research says
1 studyThis study found that older female cyclists who took beta-alanine daily for a month got stronger and could pedal harder at the end of intense efforts, compared to those who took a sugar pill — and their grip strength and body fat didn’t change, just like the claim says.
