What about the better-than-normal amount of help from insulin right after the exercise? Isn't this a
reason to eat a decent amount in the first hour or so?

Would you say that sooner is better than later because of insulin (aside from the time constraints
imposed by sleeping, etc.) ?

You mentioned "driving" insulin longer to increase absorbtion/uptake over a longer period. How do
you do this?

Sure it is. (BTW, the "better-than-normal amount of help from insulin" is the result of an increase
in insulin action, not an increase in insulin secretion...you probably know this, but others may
not). However, glycogen depletion itself is a potent stimulus for glycogen resynthesis (and
accumulation of glycogen tends to inhibit further accumulation). This likely explains why studies
have shown that by the time you get out to 24 hours, it makes little difference (in terms of
glycogen storage - a potentially important caveat) when or what you eat, as long as you eat enough.

I say sooner is better than later based mostly on knowing what it feels like to train hard and then
not eat enough carbohydrate over the next several hours....

It's pretty easy: just eat more CHO at more frequent intervals (my favorite food for this purpose is
Fig Newtons).

While TTing is my strength (and sprinting my weakness), I would describe myself as all-around road
racer - and I think other 40+ riders in the Mid-Atlantic region wouldn't dispute that claim. As for
pursuiting, I've only ridden two 3k's in my life, and only one of those was a serious effort.

W/o even knowing what's in the syringe, I submit that any benefit is purely
psychological - and I'm surprised that a physician of Testa's reputation would be into playing
such games.

Keep in mind that it's not that you produce more insulin, it's that your muscles are more insulin
sensitive post-workout.

Maybe it's what he knows about the stuff they put in their syringes that makes him so valuable :)

It is far easier for people to figure their weight than determining LBM.

We'll have to agree to disagree on this. Raspberry Newtons, heated in the microwave are my choice.
Cytomax says they contain more polylactate which allows me to train harder.

He says he's not sure if, or why it works as well as the riders say it does, but even the Tour
winner wants it.

Like everything else, it's not what you know but who you know.

Typical response from a person who doesn't know enough to get the job.
Mr. Squinczi pays him because he can help Mapei reach their goals. The proof is in the results.

Which level of ability do you need before you can sign contracts for endorsing a particular brand of
yoghurt on rec.bicycles.racing?

So is there no sense in riding over 1.5 hours, because that depletes glycogen stores so primarily
fat is available? Any other way to train for burning fats - training in the lower HR zones or
something?

If I recall over a decade back, that amino acid is also present in milk, and there are tables where

In these days one might use Google ;p

Psychological benefits don't help performance? Cf. placebo being rather efficient medicine ;)
