Improved Climbing Through Dehydration

You proved that Armstrong was lying. He wasn't really dehydrated... what
happened was some sort of drug mixup, right?

Actually, losing weight is much more important for climbing than for a flat
time trial.

in Sunday's uphill time trial, we get some pretty interesting data. The

about 9'30", while he took 20'30" to climb up to km 13 of the Alto de

this distance was 1785 m/h, visibly inferior to his performance yesterday

strange and surprising, but not really so: let's remember Lance

Armstrong's

time trial performances on l'Alpe d'Huez or Mont Ventoux, which also
resulted in inferior times to other attempts at the end of longer stages

the past.

Apart from possible external factors (such as wind and temperature), we
should remember that in a normal stage the first part of the final climb

is

usually ridden drafting from other riders, thus saving about 15-30 watts,
depending on speed. Another factor could be the body weight of the rider,
which after 4 hours of racing has usually decreased by 1-2 kg, compared to

a

time trial situation. Two kg corresponds more or less to 3 percent of the
uphill performance: on a VAM of 1800 m/h it makes a difference of more

50 m/h.

So by this reasoning the problem Lance had in that 2003 Tour time

trial

Quoted message said:

was that it wasn't a mountain time trial where he could have used that
(alleged) 15% weight loss to his advantage. By sitting in with your

buddies

for the first four hours, you should have a 1 1/2% to 3% advantage on the
dummies who let you wheelsuck for hours.

Excuse me. Gotta go. My veterinarian just arrived and I have to pack
some of my Lab's blood for use in the upcoming homologous season.

This theory seems a bit unsubstantiated. While weight plays a major
factor it's body conditon plays a equal if not greater factor in
output. Let's remember that Indurain weighed a lot more than most
climbers and he still able to out climb most riders.

Orange juice is reputed to work well in such cases of dehydration.

Dehydration is not the wasy to effectively lose weight.

Isn't there a bunch of literature that says something like " a 2% body
weight loss from dehydration results in ~ 20% performance DECLINE.

I think the answer has much more to do with riding with and getting
the benefits of the group.

Climbing with a group has some advantages such as pacing. Another
advantage is that you are able judge the other riders condition. But
the aerodynamic aspects are fairly negligible. Now I can see where
descending might provide some advantages especially if there is
multiple cols.

4 hours of racing = 5000 k-calories = about a pound and a half of fat.
(And glycogen has approx. 4/9 the energy per unit of mass of fat,
although I don't think we generally have more than a pound+ of that in
the liver/muscles.)

So maybe that's what Ferrari means?--Shayana Kadidal

Glycogen also binds with water, AFAIK, so you get rid of that, as well.

1 gram of glycogen = approx. 1 calorie (I think).

Or maybe he was just blubbering...This guy knows a lot, but really
he's just telling us the least amount so that people read it, but not
so much that we actually learn anything.

I would say that 1-2 kg of dehydration weight loss would lead to far
more performance decrement than the reduced weight would help. EPO
would help even more!

Yes, well some advantages - like pacing- is a big deal. There is no
doubt that there are both psychological and physical components to
riding/climbing. Pacing helps both.

Not.
4 calories/gram of sugar.

Note: I said "glycogen" not "glucose". 1 g of glucose is bound with about 4g
of water to make glycogen. Thus (completely botching the significant
figures), 4.182 calories of "glyocgen" weighs approx. 5 grams. So 1 gram of
glycogen will give you a bit over 0.8 calories.

Jeff

But Ferrari wasn't actually saying he was dehydrated, was he? He was just
saying that Perez had a lower amount of water on board.
