The Claim

In male bodybuilding athletes, 21 days of beta-alanine supplementation at 6 g/day combined with resistance training is associated with no significant change in growth hormone levels, contradicting the assertion that growth hormone mediates strength gains.

In plain English

In male bodybuilding athletes taking 6 grams of beta-alanine daily for 21 days while doing resistance training, growth hormone levels do not change significantly.

See the scientific wording

In male bodybuilding athletes, 21 days of beta-alanine supplementation (6 g/day) combined with resistance training is associated with no significant change in growth hormone levels, contradicting the study’s assertion that growth hormone mediates strength gains.

Why this might work

Beta-alanine enters muscle cells and combines with histidine to make carnosine, which soaks up acid produced during intense lifting. This keeps muscles from getting too acidic too fast, so athletes can lift heavier or longer before tiring, leading to greater strength gains without changing growth hormone levels.

  1. Study: Effect of beta-alanine supplementation on carnosine amount and muscle strength of the upper and lower extremities of bodybuilding athletes

    The study claims growth hormone increased in the beta-alanine group (p<0.05), but the data table shows no numerical change in growth hormone values (no pre/post values provided), and the ANCOVA results for growth hormone are not reported. This contradicts the conclusion that growth hormone mediates strength gains.
