The Claim

Beta-alanine supplementation at 12g/day for two weeks has no effect on 30-meter sprint performance 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

In plain English

Taking 12 grams of beta-alanine daily for two weeks does not change how fast trained futsal players can run a 30-meter sprint.

See the scientific wording

Beta-alanine supplementation at 12g/day for two weeks does not improve 30-meter sprint performance in trained futsal players, despite the physiological relevance of sprint speed to futsal performance and the theoretical potential for carnosine to enhance neuromuscular function.

Why this might work

Beta-alanine enters muscle cells and combines with another amino acid to form carnosine, which neutralizes acid buildup during intense activity. This should help muscles keep contracting strongly, but in trained futsal players, this process does not make them sprint faster over 30 meters.

  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 run faster over 30 meters. It didn’t—those who took it ran no faster than those who took a sugar pill.
