The 4 to 1 ratio is what Accelerade says, and supposedly they've patented
it. They've got a bunch of Journal articles on their website supporting
that. I've read separately that short chain amino acids are used for energy
in aerobic mode, and lower the rate of muscle breakdown during exercise.
Holy heck, they've "patented" it??? Not the actual ratio, no way!
Unless they funded all the studies utilizing that ratio, I
suppose...??
Quoted message said:Protein (chains of amino acids) absorb the stomach's acidity. If you eat
carbs only during a long exercise session, your stomach will get overly
acidic.
Interesting! Sounds like heartburn -- sometimes when I ingest a lot
of carbs like breads and cakes I get heartburn. Same thing?
Quoted message said:The carbs consumed during exercise mainly replenish and help maintain blood
sugar levels, although some probably finds its way back into the muscles as
glycogen. If you've ever done a long term run and gotten weak and dizzy,
that's a sign of low blood sugar, and means you haven't been eating/drinking
enough carbs.
Most I ever did was fifteen miles on the treadmill, at 2:45. I don't
remember feeling weak and dizzy, necessarily, but I always feel
"happily drained," no matter what the distance.
I'll trying having a carb/protein drink next time and see if that
helps.
Quoted message said:Most endurance runners (multi hour events) consume roughly 200-300
calories/hour in the form of snacks/gels/energy drinks.
Yeah, I've always wondered about that. I didn't even have water on
hand while running on the treadmill. I never do, actually. I only
drink after a run; I never interrupt a run for a sip, and I don't run
with any bottles or packs on me.
But now that I'm 35 and just starting to feel kinda weird sometimes,
I'm looking into all these things; hence my questions.
Quoted message said:Don't know about distance runners ever using the stuff -- sounds like weight
lifting Chemistry to me...
Yes, you're right. Apparently creatine draws water into the muscles
and adds more weight thereby (though supposedly swelled muscles make
for faster protein synthesis).
Quoted message said:When warmed up in aerobic mode, the tendency to get a low blood sugar
reaction to pure carbs is greatly reduced -- glycemic index isn't much of a
factor for most folks. So the type of carb isn't particularly important.
Right -- for runners!
But hi-gly carbs are supposed to be most efficient at loading protein
into your system. Even for runners that's important, especially since
protein is supposed to be burned, two, past two hours of exercise.
All that from "Nutrient Timing," which is focused on the strength and
speed athlete, but still, muscle is muscle and there's a lot of cross-
over benefits if this stuff is true....
