Commenting on stage 11, Dr. Ferrari at www.cyclingnews.com said this:
"Together with a perhaps too generous Axel Merckx for 130 km, the French rider gave his best in the last 2 hours of the stage: while Axel ran out of fuel (read: glycogen), Virenque's metabolism, privileging the use of fat as energetic source, allowed him to spare glycogen stores for the final part of the race."
How does one determine whether a rider is burning fat or glycogen? Two Ph.D.s and one surgeon so far have been unable to figure this out.

Who are the two PhDs and one surgeon? Supposedly, people burn a higher percentage of fat at lower effort. Perhaps Virenque was using a lower effort?

It is just an experienced guess. The fact that Richard continued after Axel bonked gives you the idea that Axel was burning his glycogen at a relatively faster rate. They were both using fat as engergy sources or else they would not be able to finish a single stage. Doesn't it then follow that the guy that does not bonk is using fat more efficiently?

Ferrari is a disciple of Conconi, and is just one of several Italian sports doctors on the leading edge of world training research begun by Conconi and others 2 decades ago. While Ferrari may have assisted some riders in doping, LA probably didn't choose him for that, but for other training methods. Undoubtedly, Carmichael learned those methods along with LA and adpated the training program for LA based on what they both learned. It would include lacate measuring and other metrics to determine training pace and recovery times, etc. The Italians have been ahead of other researchers on this.

No. After a 130km breakaway, the guy who does not bonk is eating more intelligently during the ride.

Lots of ways, but none particularly conducive for use out on the open road - one of those portable metabolic "carts" would be your best bet.

Huh?
W/o any measurements whatsoever, I can state with nearly absolute certainty that both Merckx and Virenque were oxidizing a mixture of both fat and carbohydrate during their escape.

And here I was thinking that it meant that Virenque could burn fat at the same rate but only had to lift 3/4's the weight over the mountains. What WAS I thinking?

You really shouldn't slander people like that. So far there are no charges against Ferrari who, it may very well turn out, did nothing more than explain to riders what drugs did what and what their dangers were.
Would you agree that if you were a doctor and you suspected that some riders in your care might resort to drugs that you might feel a responsibility to make sure that they knew enough about it to not harm themselves?

fitness plays a bigger role. if you're not fit enough for the intensity you're trying to ride, no amount of food will prevent bonking.
