Beta-Alanine Suppl. Effective for Women!

Effects of beta-alanine supplementation on the onset of neuromuscular fatigue and ventilatory threshold in women.

Amino Acids. 2006 Nov 30; [Epub ahead of print]

This study examined the effects of 28 days of beta-alanine supplementation on the physical working capacity at fatigue threshold (PWC(FT)), ventilatory threshold (VT), maximal oxygen consumption ([Formula: see text]O(2-MAX)), and time-to-exhaustion (TTE) in women. Twenty-two women (age +/- SD 27.4 +/- 6.1 yrs) participated and were randomly assigned to either the beta-alanine (CarnoSyntrade mark) or Placebo (PL) group. Before (pre) and after (post) the supplementation period, participants performed a continuous, incremental cycle ergometry test to exhaustion to determine the PWC(FT), VT, [Formula: see text]O(2-MAX), and TTE. There was a 13.9, 12.6 and 2.5% increase (p < 0.05) in VT, PWC(FT), and TTE, respectively, for the beta-alanine group, with no changes in the PL (p > 0.05). There were no changes for [Formula: see text]O(2-MAX) (p > 0.05) in either group. Results of this study indicate that beta-alanine supplementation delays the onset of neuromuscular fatigue (PWC(FT)) and the ventilatory threshold (VT) at submaximal workloads, and increase in TTE during maximal cycle ergometry performance. However, beta-alanine supplementation did not affect maximal aerobic power ([Formula: see text]O(2-MAX)). In conclusion, beta-alanine supplementation appears to improve submaximal cycle ergometry performance and TTE in young women, perhaps as a result of an increased buffering capacity due to elevated muscle carnosine concentrations.

The study is neat and all, but why is there a link at the bottom to a file on your desktop?

Oops, sorry about the link. Here is the link I ment to post.

The study is crap. The authors don’t know what they are doing. :wink:

Thanks for the heads up Dr. Stout!

BTW-How long has Dr. Harris been in the US?

LOL! NICE! Dr. Harris travels quit a bit between the UK, USA and Asia. His home however is in the UK.
