The Claim
Two weeks of 12g/day beta-alanine supplementation does not reduce perceived exertion during high-intensity intermittent exercise in trained futsal players.
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 12 grams of beta-alanine daily for two weeks does not lower how hard athletes feel they are working during intense, stop-and-go exercise.
See the scientific wording
Perceived exertion during high-intensity intermittent exercise is not reduced by two weeks of 12g/day beta-alanine supplementation in trained futsal players, despite the theoretical role of carnosine in delaying fatigue perception.
Beta-alanine enters muscle cells and combines with another amino acid to form carnosine, which neutralizes acid buildup during intense exercise. This acid buffering helps muscles keep working longer, but it does not make the person feel less tired.
What the research says
1 studyScientists gave futsal players a supplement called beta-alanine for two weeks to see if it made them feel less tired during intense play. It didn’t — they felt just as tired as those who took a sugar pill.
