Beta-Alanine Studies (Need 'em)

[Cloud Strife]

Oh hei aghen guise!

So I'm moving right along with my little project and I seem to be having trouble finding some studies conducted on Beta-Alanine. I searched PubMed but haven't been successful.

Anyone have any links to some good studies?

Greenz for help

P.

P.S. I know this isn't the Supp Sci section but there is way more foot traffic here (as well as more of the learned people come here too).

I would pm a AEN rep

they are usually very quick with the BA studies

EDIT: also this may sound silly/obvious but have you tried googling 'beta alanine studies'

beta-Alanine and the Hormonal Response to Exercise.
Hoffman J, Ratamess NA, Ross R, Kang J, Magrelli J, Neese K, Faigenbaum AD, Wise JA.

Health and Exercise Science, The College of New Jersey, Ewing, New Jersey, United States.

The effect of 30 days of beta-alanine supplementation (4.8 g per day) on resistance exercise performance and endocrine changes was examined in eight experienced resistance-trained men. An acute resistance exercise protocol consisting of 6 sets of 12 repetitions of the squat exercise at 70 % of one-repetition maximum (1-RM) with 1.5 minutes of rest between sets was performed before and after each supplemental period. Blood draws occurred at baseline (BL), immediate (IP), 15-minutes (15P) and 30-minutes (30P) postexercise for growth hormone, testosterone and cortisol concentrations. A 22 % (p < 0.05) difference in total number of repetitions performed at the end of 4 weeks of supplementation was seen between beta-alanine (BA) and placebo (PL), and Delta mean power was greater in BA (98.4 +/- 43.8 w) vs. PL (7.2 +/- 29.6 w). Growth hormone concentrations were elevated from BL at IP and 15P for both groups, while cortisol concentrations were greater than BL at all time points for both BA and PL. No group differences were noted. No change from BL was seen in testosterone concentrations for either group. Results indicate that four weeks of beta-alanine supplementation can significantly improve muscular endurance during resistance training in experienced resistance-trained athletes. However, these performance gains did not affect the acute endocrine response to the exercise stimulus.

OMG I hadn't even thought of Google!

Alright, I'll PM the guys there. Thanks dude

Hmm...not sure how I missed that one. I clearly have **** search skills.

Thanks bro - I'mma look that one up!

Stout JR et al. Effects of beta-alanine supplementation on the onset of neuromuscular fatigue and ventilatory threshold in women.Amino Acids. 2006 Nov 30

Department of Health and Exercise Science, University of Oklahoma, Norman, OK, U.S.A..

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.
