Is this true? A climbing tour de france rider demands a furious release of energy higher than any other animal on Eart

Not only do they try to but they often succeed. For them to succeed they do not need to run faster than the eagle can fly. They only need to run fast enough to slip into a crevice where the eagle cannot follow.

That's evading, not outrunning but we're talking watts per kilo here.

Hold on a second. You're going to object that this is not actually outrunning an animal that isn't even running at all?

Objection overruled!

An elephant fart releases more energy than a tdf rider climb.

Of course it's credible. Even though a few mammals can be taught to bike, none of them are near the absolute or relative output power of a TdF cyclist.

According to a single study released less than a year ago.

I just read the study, and it seems they measured "body temperature" via sensors in the abdominal cavity. That's pretty weak because exercise-induced hyperthermia starts in the working muscles. I don't see any reason to expect an increase in core temperature within 40 seconds or so of a cheetah starting to sprint.

But, having sprinted in hot weather many times myself, I do expect to see a sustained increase in core temperature after a 40-second sprint, just as the study found for cheetahs. It also found that the temperature increase was greater for cheetahs after successful hunts than aborted ones, just as I sweat more after a complete all-out rep than if I step off the track early. And while the successfully-hunting cheetahs didn't usually end up with core temperature above 40.5C, their average increase was a significant 1.3C, and it would make sense for them to leave a margin of safety so they can combat or escape from competitors after the kill.

So it seems more likely to me that the cheetahs abort most of their hunts because they either would be dangerously close to overheating afterward if they continued, or because the resulting sustained core temperature increase would interfere with second attempts for the next hour or two. I also have little doubt that a cheetah that attempted to sprint indefinitely would fare differently than the cheetahs studied which did not.

Whether the hyperthermia is exercise-induced or not, they propose no mechanism or evidence supporting stress-induced hyperthermia. All they've got is

which is at best evidence that a cheetah can get warmed up by means other than a sprint, and that a cheetah can suffer stress, not that stress hyperthermia is actually occurring. They are speculating.

A sprinting cheetah uses so much energy that it will drop dead in its tracks from hyperthermia if it sprints too far. It stops when it overheats, not from fatigue.

Ya smoke a little too much Lebanese red and you start making up all sorts of crap.

Btw - how fast can an eagle run?

Fast enough.

Read the post just before yours, fool.

OK, in watts/kilo: A hummingbird flying uses more energy/gram/sec than any Tour rider has ever or will ever remotely approach.

Gibney said they released more energy than any other animal on Earth except the hummingbird.

This is still FALSE. Wildly false. Lots of small animals besides hummingbirds use prodigious amounts of energy per unit of body weight.

For instance, the pygmy shrew has a resting heart rate of 800 bpm. Let's see Lance top that! To fuel it's metabolism it consumes its entire body weight in flesh every day. So, for a 150 tour rider that would be equivalent of consuming (and burning off) 150 pounds of meat per day. Do you think that Lance & Co. were consuming 200,000 kcal per day? Or that they were burning nearly 10,000 per hour on their climbs? Somehow I don't think so.

I watched The Armstrong Lie last week and Alex Gibney made that quote. I found it very hard to believe. Is there anyone with more knowledge than me who could tell me how credible this quote is?

It's a very stupid and ignorant statement, cycling experts make them all the time.

Isn't the answer always the prong horned antelope?

I'm glad we finally outed Gibney.

Fake.

wait... what site is this? you respond with a reasonable discussion of the previously mentioned points, and cite peer-reviewed research?are we on dyestat?also big ups to the link to the eagle/goat video

Fake.

Even if it's a fake it's documented that eagles do regularly attack and kill young goats.

Maybe staged but not fake. You can find plenty of photos and videos of golden Eagles attacking and killing deer or Pronghorn.

Martial Eagles and Crowned Eagles of Africa also kill Antelope up 70 pounds or so.

Google is your friend.

Nope. Pronghorn.

Yesterday I did 380 Watts for 20 mins at 137 lbs. I like to believe I could rip the wings/legs off a hummingbird.
