Do you take your bcaa pre or post workout? or both?

[tp_88]

I dont think so. In order for protein synthesis to occur you need to have all the essential aminos present in the correct amounts. If one is limited or missing protein synthesis cannot occur. So BCAAs do not provide all the essentials for it to occur which would mean pro synthesis does not occur. Although BCAAs provide 3 of 9 EAAs the other 6 must come from sources like whey, tuna, beef, etc.

So you mean that your body doesn't have access to the other amino acids? The only source is what you ingested 1minute ago? Again, BCAA/EAA and other free, essential, amino acids (L-Leucin might the most potent one) elevates the protein synthesis more then any intact protein does.

One study before I return to the TV and the Olympics:

BCAAs (leucine, isoleucine, and valine), particularly leucine, have anabolic effects on protein metabolism by increasing the rate of protein synthesis and decreasing the rate of protein degradation in resting human muscle.

Youll have some free amino acids in the bloodstream if you consistently get protein coming into your diet every few hours. The body likes to use protein fairly quickly after it has been digested, absorbed, and assimilated. So if you are taking whey iso w/ water on an empty stomach it will get digested and absorbed fairly quickly since there are no other macros needing to be processed. All EAAs will elevate protein synthesis but you must have all them for it to occur. Its an all or nothing principle. You can "elevate" it as much as a particular AA can but if all 9 are not present it will not occur.

Now if you have all 9 EAAs in that form protein synthesis will happen faster because they will not need to be broken down from the whole protein molecule. But if you are working out at the time protein synthesis is not the priority at hand so the body will allocate its resources to the stress (exercise). During exercise very little blood is received by the digestive viscera so digestion and synthesis of anything do not occur or occur at a rate that does not benefit the system.

After exercise individual EAAs (all 9) will promote faster protein synthesis. Now Im not saying that we should only consume AAs in that form because then at the receptor level the AAs will compete with one another for absorption. The "speed" that promotes protein synthesis is not that drastically different in healthy individuals when the aminos are received in the form of AAs vs whole protein. So consume whole proteins preferably because they provide AAs in relative ratios that the human body can best utilize.

I understand that BCAAs have an anabolic/anti-catabolic property to them. What I am trying to get across is that the body needs all the AAs present in the given amounts for protein synthesis to occur. BCAAs do promote protein synthesis only if all the necessary AAs are also present. That is why I would advocate eating whole proteins as opposed to just BCAAs or EAAs. Complete proteins have them both already in them in fairly correct ratios.

[tp_88]

But come on, all the AAs are there to be used if the MPS is elevated. Whey Isolate in water on an empty stomach will be absorbed quickly, but a large portion of cottage cheese won't. Or a big steak or whatever. Very few people take in all their protein from whey-shakes... And then there is broken down muscle protein which is re-used in the protein synthesis and so on.

I take them intra-workout.

[BuffGuy]

I used to take Bcaa before workout..
now i just eat a small meal before and after workout.

["Rodz"]

I just started taking "Gear" from Needtobuildmuscle, I'm taking them 3 x throughout the day

[lilarnold]

False.

AAs and long protein chains doesn't have the same impact on protein synthesis. At all.

differences are negligible.....try it. i could give two shits what some lab rat said....real world results speak volumes.

try chicken and rice pre workout and steak and eggs with some pancakes and syrup post and have a friend take aminos........after 6 months you tell me who grows more muscle

[lilarnold]

Even if they wouldn't be used in the protein synthesis (which I doubt, but I'm not sure) they still stimulate it way more then whey, tuna, beef or any other intact protein does.

uh........nope

real food is ALWAYS better

exactly.......it doesnt matter how fast it happens...as long as it does

[Cooker]

this is why i take PURPLE WRAATH

It has all the essential amino acids. not just the branched chains.

FTR it does not have all EAA's. Just sayin'

[Timbo89]

I take 5 Six Star BCAA quick-dissolve tabs 1 hour pre-workout, !

i find tabs suck.

[Triple-H_2005]

I've used them Pre, during and post, 5 grams each serving. I did this for a consistent 5 month period, then reviewed my progress.

There were no substantial gains that were not seen during other periods using whole foods and whey/waxy maize shake pre and post workout... only an emptier wallet.

I KNOW what all of the studies say, but when the ONLY thing I did differently for that three months was to use the BCAAs, and saw no difference, I consider it a waste of money.

Others may disagree, but it really did me no measurable amount of good.

Chained out all day long !!! Love appletini yum wish they would make a watermelon or a citrus. Shit rocks!!!!
