New Beta-alanine study, looking at training volume, power and hormonal chan
Another beta-alanine study hot off the press, has recently been completed. The researchers looked at performance and hormonal changes in eight experienced resistance trained men when supplementing with 4.8grams of beta-alanine per day for 30 days, compared to a placebo. The study was a double blind, placebo controlled, cross over design. Six sets of twelve repetitions at 70% of their one repetition max were performed. The beta-alanine group had a 22% difference in the number of repetitions and the mean power for the beta-alanine group was higher than the placebo. In agreement with previous beta-alanine studies, no significant hormonal changes were shown compared to the placebo, when looking at growth hormone, cortisol and testosterone concentrations. Simply put, this study showed beta-alanine can help you perform more repetitions, without negatively impacting the normal exercise induced hormonal changes.
