By the way, I mentioned “athletes” so bare in mind it has nothing to do with bodybuilding. Quote from Lyle McDonald from Chalie Francis’ site:
"Previous work on glycogen restoration has suggested intakes of 1.5 g/kg immediately after and again 2 hours later. Protein at 1/3rd of that is a common suggestion. That’s where those numbers are coming from. Look up anything by John Ivy or Ed Coyle.
Note (this in reference to comments later in the thread) that these types of studies are looking at glycogen depletin exercise, exhaustive endurance stuff, high rep/high volume bodybuilding stuff. Their relevance to the types of low volume, CNS dominant work in many sprinting/maximal weight training methods is questionable.
That is ,a bodybuilding doing 20+ sets of high rep work is depelting lot of glycogen, stimulating protein synthesis; an endurance athlte doing 40 minutes at LT or 2+ hours aerobically is as well. A sprinter running short repeats on a full recovery is not.
Nutritional recommendations have to be based on the metabolic requirements of the athlete and the training being done.
I don’t think a high GI/protein drink is necessary or beneficial following pure CNS work. Restoration of fluids and maybe creatine or something.
Following extensive work in the glycolytic range, absolutely.
For bodybuilders wanting hypertrophy, absolutely.
For endurance athletes, absolutely.
It’s all about specificity.
Hyperinsulinemia + hyperaminoacidemia have syneergistic effects in terms of storing glycogen, inhibiting catabolism and promoting protein synthesis. Do a medline search on Biolo to get started. Hence the emphassis on high GI, insulin spiking compounds.
Again, this is more important for an athlete involved in training that depletes glycogen and strongly promotes protein synthesis, far less so for a CNS dominant athlete. As Charlie pointed out, save the high GI + protei nstuff for the extensive sprinting workouts, special endurance and that stuff."
Quote from Kelly Begett(sp?), T-Nation forum contributor:
"IMO, if one can’t voluntarily eat enough to replenish the glycogen depletion brought on by an activity such as sprinting and/or weight training, then you either too poor to buy food or there’s something wrong. If you ain’t losing weight from your activity then you’re not “too catabolic”. If you’re a marathon runner or a distance athlete then yeah.
But the amount burned during these anaerobic activities is so inconsequential anyway. To deplete even 100 grams of glycogen requires a fair bit of anaerobic volume. You’re talking 30-40 sets of bodybuilding training with each set 45-60 seconds long. And 100 grams of carbohydrate?? Hell, I can easily eat that much in a midnight snack getting up to take a piss. Same goes for protein intake. If you can’t get a gram per lb of bodyweight then you’re not eating.
And it’s not like quality isn’t made up for by quantity. Dextrose, glucose, sucrose, maltodextrin, potatoes, bread, cereal, oats, beans, rice…they all go to the same place. And if there were a huge advantage for a power/speed athlete to store more glycogen then they would be practicing carbohydrate depletion/loading.
It’s all a matter of perspective. The average athlete thinks that the special formulations contain magical substances that do stuff that foods don’t do. For example, they’ll think that dextrose and maltodextrin do something to the muscles or are stored in a certain way that regular foods aren’t. Which is bull and this is what irks me. Use a PWO formulation for convenience not necessity."
