After posting an answer to query on another forum about AA’s, I did some reading. In the recent edition of Powerlifting USA, Mario di Pasquale reported on a study (see below) concerning the use of BCAA’s in peri-/post-workout supplementation. The study found that those individuals who took in 6g (this amount was the “optimal”- less produced less of a response, more made no improvement) of BCAA’s, had a more favourable hormone response (T, IGF, GH etc), and better strength and LBM gains, than 6g protein, or placebo. The study also found that adding extra carbohydrate, or protein to this BCAA cocktail, did NOT purvey any further benefits. I find this rather controversial, especially the last point about extra protein/carbs having no effect. I did not read the article myself, so I don’t know what the rest of these individuals general diet was. I would presume their diets were pretty good outside this post-workout period to ensure anabolism was optimal(?). Di Pasquale does summarise that he would still recomend additional protein post-workout, and up to 48 hours after when the muscles are in recovery.
The reason I mention this, is because in my other posting I talked about my not using AA supplementation, preferring just lots of good quality protein. Way back in the late 80’s/early 90’s, when I was still using Weider Mega mass, and Vanadyl was the latest wonder supp. (remember then?!), I did buy into BCAA’s for a while. Did nothing noticeable for me that I could see. However it might have been the rest of my diet then (I was totally clueless compared to now), and I probably was only taking in piddly amounts (I don’t remember). Never used them since, and didn’t think much more about it till now.
So, have I been missing something? How many of you guys out there use BCAA’s regularly, and have you seen much effect? I’m thinking of starting again, but it would be a fairly big outlay for my budget currently, especially with the amount needed IMO for effect. If the response is favourable, would there be any recommended brands? I would guess that a fair amount of Glutamine, Taurine, Leucine would be important, but not being an AA guru (although I remember my senior biochemistry year vaguely) that’s just a guess. Thanks for any info, sorry for the long post. SRS.
