the talk earlier in this thread about leucine pre and peri workout got me thinking…
I use TrueProtein’s creat your own mix blend, and was wondering what a good pre workout mix would be… I was thinking about 80% whey, 10% BCAA and 10% Leucine, and adding carbs like gatorade as my diet saw fit… A 50 gram serving would give me 5 grams luecine and 5 grams BCAA.
How does this seem? I know it’s not an exact science, but if you have suggestions I’d love to hear them.[/quote]
Actually it’s really not good at all. At least, very far from being optimal.
The reason why leucine is being made in isolation and sold is that it was found that leucine by itself (it is one of the three BCAAs) is more effective that when the full BCAAs are used. The two other BCAAs (isoleucine and valine) actually compete with leucine for transport.
So right off the bat, the 5g of BCAAs in your formula is a relative waste.
Whey can be a good idea, but it depends on the type. Isolate is fast enough, but lacks in the immune-boosting microfactions. Whey concentrate has those elements but unless it’s a very high quality concentrate (80%), which is normally what is used by most companies, then it’s too slowly absorbed for pre-workout purposes.
Whey hydrolysate would be a very good choice, but the best one would actually be casein hydrolysate which is the fastest absorbed protein. Other types of casein wont do because they are too slowly absorbed.
BUT you can’t have too much protein otherwise you will have the same problem with leucine as when the other BCAAs compete with it.
To maximize the effect of the pre-workout drink, other products can be added such as beta-alanine.
The strategy that I’ve come to adopt now, and I tried EVERY THING a human being can think of, is this:
45 minutes before workout: 30g BCAAs
PRE-WORKOUT (15 min): Surge workout fuel 1 scoop, whey hydrolysate 1/2 scoop
DURING-WORKOUT: Anaconda 1 scoop (gotta have to wait a short time to get this one guys)
POST-WORKOUT: Anaconda 1 scoop, Surge Recovery 1 scoop
