TDF hydration question

shane said:

Was listening to the eurosport feed on friday, and heard them
mention that if the riders didnt drink a certain amount of water
within 15 minutes after the end of the stage, they would not finish
the tour. It had sounded as if it were the results of a study.

Does anyone remember hearing something like this or know anything
about this?

thanks

Yes, there is a lot about this.

After a big effort you have to fill up water and Carbonhydrates ASAP.
It's proven that you have to do this immediately after the effort, or
you will not nearly recover as fast.

According to Peter Winnen among the first who realised this was Lemond.

I know that you have to rehydrate after an effort, etc, but they were
very specific about the amount and time you had after the end. This is
what I was asking about.

Thanks

According to the authors, the amount of stored glycogen in skeletal
muscles influences exercise performance, and delaying carbohydrate
ingestion for 2 hours after a workout can reduce the rate of glycogen
resynthesis by half. Studies noted by the authors have suggested that 50
to 75 g of carbohydrate be ingested within 30 to 45 minutes after
exercise, with ingestion of 1.2 to 1.5 g carbohydrate per kilogram of
body weight per hour for the next few hours. Protein ingestion also has
been shown to hasten the rate of glycogen synthesis. CR and FR, which
replenish fluid and electrolytes lost during exercise but contain less
carbohydrates, are 2 types of postexercise drinks that have been
formulated to address glycogen synthesis and carbohydrate replacement.

I think you're talking about the big study involving chocolate milk and
cyclists. Horner now drinks chocolate milk with his Quarter Pounders
(Burger Royal in France).

Soya milk and fudge is pretty good too.

Maybe that's what you need to give a good sample, else you're out.

That's the chocolate milk article above. It seems like water alone is a
bad idea after races.

While water is fundamental to this process, it is not enough. Indeed
replenishment tied to water only could easily lead to hyponatremia, or
water intoxication, a condition resulting from the extreme dilution of
sodium in the bloodstream.

Our CSO has pointed out that this is an exaggeration:

Good point. Also, the riders do eat and drink during the
stage - though you can't drink enough on the bike
to replenish well during a long hot stage.

But the real reason that the riders have to suck down
water directly after the stage is that the stage finishes
and 1km kite are sponsored by Aquarel.

Probably has more to do with doping control than with actual
rehydrating. Can't pee into a cup if you aren't hydrated.

So presumably if Ryan or Curtis were doing the fatty master tdf they'd go
on strike if the kites were sponsored by Millers instead of a Belgian beer
company.

Pulling into a pub and not rejoining is not exactly a strike. Perhaps
a sit-in.
