The Claim

Two weeks of 12g/day beta-alanine supplementation does not reduce perceived exertion during high-intensity intermittent exercise in trained futsal players.

Source: High-dose beta-alanine supplementation for two weeks did not enhance intermittent endurance or sprint performance in trained futsal players

Cause and effect
1 study reviewed
In plain English

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.

Why this might work

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.

  1. Study: High-dose beta-alanine supplementation for two weeks did not enhance intermittent endurance or sprint performance in trained futsal players

    Scientists 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.
