I am curious to know..... how does the amount of protein ingested by the time you work out - alter your gains/workout/recovery??

If my total daily protein consumption is aimed to be 200g, say I ingested 100g by the time I went to workout. How would that compare to if I ingested the whole 200g?

Anybody know anything about this, or any links to scientific study on this???

Good Question? Bump

Well I can tell you this much: if you consumed all of your daily protein before your workout, you wouldn't have any protein post-workout, which is when it's the most crucial.

Yeah, I realize that.. But in order to maximize my gains is there a certain amount I should definately eat by the time I workout? Or does it have no impact?

before you workout, or before any strenuous activity, your body can only utilize 40g of protein in each meal. Going over that does you no good, keeping a constant intake of protein would be optimal IMO.

Isn't that all dependent on the time frame and rate of absorption? But yeah I just try to keep a constant intake of lower BV proteins (i.e. meat ). Caloric restrictions limit how much I take in w/each meal anyway.

Can you give me a citation from medline for the abstract of the study that came to this conclusion? I've heard various numbers thrown around from as low as 25g in one sitting to as high as 50g in one sitting yet nobody has ever cited a study. If you have one I would love to read it, otherwise it's just an opinion. The best I've gotten from PHD's in college was, "Protein absorption and utilization varies from individual to individual."

That's probably the reason that anybody who's given you an actual figure can't provide the experimental evidence to back it up

 

[vin01]

Well it must depend on the individual: if you are to intake 200g vs 300g protein over a day with 6 meals (bc of your BW), you would be eating 33g/meal vs 50g/meal.

I would love for someone to come up with a well designed study comparing a why isolate, caseinate, and say egg white at various protein levels. Say 20g,30g,40g, 50g, 60g. My feeling is that utilization will vary dramatically among protein sources at the higher levels. The Boire study found much of whey protein is highly underutilized due to it's rapid absorption; Much of it gets converted to glucose as the body is so rapidly flooded with aminos, at least that was his supposition.
