Those weren't there last week.

She's obviously using those to make herself faster, facing forward anyway. I wonder if they're a special lightweight formulation . . . otherwise she must be trying to make the races a little more exciting. I read she had a 10 1/2 minute lead with 15K to go in one stage. Geez, don't these other women train?
She should go to Europe, obviously out-grown N/A scene. nmSpunout

Question: where does Jeanson's power come from?5ive

Time and time again, I find her performance simply mind-blowing. I have no trouble accepting the fact that she's a very gifted athelete who can do it all. But some of her results in TT's and the mountains often rival that of men's. And this year, she's even winning the field sprints. I click on every one of her pictures on the web trying to figure out if she has a great TT position, dropped another pound (if that's even possible), or legs built like Cippo. And everytime, I'm left with even more questions than answers as to exactly where she generates all that devastating power from. If her freakish performances were limited to a race or two, I can understand that. But so consistently she's making each race she enters look like it was a training ride against club racers. How does she do this? Any guesses?
must be the High Power C40. nmDougSloan

of the often falsely held notion that you need big muscles to produce high sustainable power!

Her legs are smaller than many fat crit-racers arms!

What you need to produce high sustainable power is:
A CV system that can deliver lots of oxygen to the muscles (i.e. big heart, big lungs, dense capillary beds in the muscle leading to high capillary to muscle fiber ratio)
and then muscles that can use that oxygen which mainly means muscles with alot of mitochondria volume (and the associated enzymes of oxidation).

To produce big power for a long time you don't need to produce all that high of forces (which big muscles are good for), you just need to produce relatively low forces over and over and over and over (i.e. have very fatigue resistant muscles)!

As to winning field sprints, I suspect her fitness is so high, that she is sprinting in a much less fatigued condition that her rivals. Given her small muscle size, I would be shocked if she could produce more power than her rivals in something like a Wingate Test.

OK, but with respect to "big lungs," I'm not sure there isn't a falsely held notion there as well. I remember reading a column by Jonathan Vaughters where he indicated that lung capacity isn't really the factor conventional wisdom makes it out to be, since most people's lungs can take in much more oxygen than their muscles can process. He pointed out that Greg LeMond won two Tours with a lung that remained partially collapsed from his hunting accident. Efficiency in processing oxygen is the key, which anyway is a more interesting discussion than whether or not someone's jersey is unzipped or just what that thing is in Stuart O'Grady's shorts.
Well...Dwayne Barry

you're probably right. A minimum lung capacity is probably necessary to be an excellent endurance athlete but beyond that may not do one any good. I think what you mean by efficient at processing oxygen is really a large capacity to process oxygen, no?
Yup ...Will Ross

That is what I meant. Nor do I claim to be an expert, but I keep reading stories about the lung capacity of various athletes -- the fascinating Bicycling article on Graham Obree being the most recent example. It's interesting to me as someone who has always been very poor (well below average in fact) at endurance sports. Why I chose to take up cycling only my subconscious could tell you. I've always wondered if lung capacity has been what has held me back, since I would always be breathing hard well before everyone else when jogging, etc. After nearly two years of hard training for cycling, I am able to keep up with many of the stronger members of the local cycling club, and am beginning to stick my toe gingerly into the racing end of the cycling pool. So as someone who is distinctly genetically ungifted and who has consequently had to fight extremely hard for every tenth of a mph of improvement, I find the details of performance and physiology interesting and pertinent.
