This comes to you from the Dept. of No **** we Knew this 10 years ago
Sherlock. The only confusion comes in that carbs don't appear to affect
protein SYNTHESIS (an increase in insulin prmiarily affecting protein
breakdown, decreasing it). HIgh AA concentrations stimulate protein
synthesis. Cobmining the two (high insulin + high AA) gives better
results, something that's been known for years.

But thanks for being on the cutting edge of about 1995 or so.

Lyle is right. It is 'old news.'
Tipton/Wolfe and Ferrando, the protein metabolism kings ("We're all
about protein metabolism" - private conversation), have demonstrated
that AAs are superior over carbs for protein synthesis. In fact, a
colleague of theirs demonstrated that simultaneous intake of carbs
WITH AAs actually reduces protein synthesis in elderly compared to AA
intake alone. (study published last year).

The signaling pathway downstream of the insulin receptor in muscle
diverges from that which induces protein synthesis, and leads to a
reduction in the catabolic pathway of protein. Hence, the reason that
the studies demonstrate that insulin reduces catabolism, but does not
significantly increase protein synthesis.

Well, your post about 'carbs aren't supposed to help muscles' is just
as ignorant.

This may help you understand this newsgroup.

Pay particular attention to # 19, # 23, # 24 and the closing

remarks.




Thanks for the fine info, Lee.
Had I realized I was including the viagra users' group in my comment,

I
would have made appropriate allowance for the general level of

intellectual
discourse attained over there!
Sorry, ;-(
MikeV

there are some pretty good people in this group - this guy just happens

to
be a prick


I'm relieved, Dave.
Apologies to all said 'good people', sidenafil citrate users, and all
disadvantaged folks wherever they may be surfing.
Sincerely,
Mike

LOL!

That is a harsh reply to an informative article,


Not really.

one that you yourself learned something from.


I doubt it.

Perhaps you could give us a reference to the 1995 studies you refer to
above, so that we may place the current work in better perspective.

Mark


This ought to be good.

Lyle also happens to be a supremely well-informed prick. Unfortunately, he
knows it.

McD is a "big fish" in a small pond; His area of 'expertise' is
narrowly defined and confined, with the consequent effect upon those
other minnows who he considers to be less well-informed!!

He is also a self-confessed pervert who obsesses about his
self-administered sexual 'adventures'!

It's called knee-jerk research: PhD's tryna keep/justify dey jobs.
Sorta the way Lyle posts 40 abstracts on a subject, not knowing
what a single one of them really sez.

It doesn't seem to be "old news" to the scientists involved in the research.

*Sigh* You really think that something that was released in February
2004 is "too old"?
