Was reading the thread about Bolt's lifting (light w/ lots of reps) and the comments about how much real, elite sprinting stresses the Central Nervous System, and started to wonder how much energy these guys expend in say a 100m or 200m race. They are obviously ripped and have practically 0% body fat, so they must be burning off a lot of calories, or else somehow everything they eat turns to muscle, because I imagine they are also eating a lot.
Distance doesn't really matter much. Between the 100 and the 200 and 400, there is not much difference if you go all out. Then there is a significant drop. Because top speed goes down so much between 400 and 800, the 800 burns a lot less energy.
I am not talking about the energy burnt DURING the race, but including the next 30min.
When you begin to understand this fact you understand why there are so many long distance SKINNY FAT people.

Wow, I can't believe I am finding myself understanding/agreeing with Xfit_guy. I was guessing that the body is taxed for a while from an all out effort.
I'd still like to hear a response from Sprintgeezer or coach b, as they wre both posting in the Bolt thread.

XFit guy is completely out of his realm of expertise with this one. That was blatantly obvious when he dropped the skinny fat comment.
Relative to races like the mile, 5k, 10k, sprinters probably are not burning as many calories in one race. When sprinters go through heats, semis, and finals, then they rack up the energy consumption. At the real elite (Bolt, Gay, Blake, etc) level, I have to imagine they expend a LOT of energy because they are trained to expend all of their energy over a very short distance.

Can you please post a study done on this? Should be pretty straightforward, look at wattage output during the race and then following the race, knowning time periods can get calories, kWh, kJ, whatever form of energy you want.
A sungle sprint race doesn't burn much
They are lean for genetic reasons, not because of their training.
3000 calories/hour for 20 seconds = 16.66 calories, and that rate of burn is a high WAG.

To be fair your calories/hour will be much increased for a time after that which is what others have said on this thread. There is a reason sprinters are sweating and breathing hard long after their race and it is not because they aren't in shape. I'd just like to see some actual numbers.
130 calories a mile....same as anyone else

That is obsurdly not true.
Sorry baby, they go way faster than you, but they have more efficient engines than you too. The calorie burn is the same. A mile is a mile and the energy to cross it is the same.
They don't burn much when they race.
But they do burn a lot when they train.

So wrong. Use your brain for a second and tell me why that is incorrect.
If a 200 pound sprinter jogs a mile he will burn around 180 Calories (kcals)so that's about 11 or so per 100m
In a 100m race, wind resistance is much higher though, so maybe 30 Calories during the race and a lot more to recover. That's where the real calorie burning takes place for a sprinter.
It's amazing how much power an elite sprinter is able to generate over the 9+ seconds of a 100m. Watch a sprinter before a race when they he is tense, but not breathing hard or sweating, and then again right after the race when he is being interviewed. He'll be gasping for breath and sweating like crazy. Elite sprinters create power through the burning of energy. They use way more energy to cover a 100 meters than does distance runner. Of course a 100 meters isn't very long, so the total amount of calories burned during the race is not that much. After the race their metabolisms remain raised and that's when the calories are burned.
As an aside, I got injured 4 weeks ago and had to stop running, but immediately started hitting the gym rally hard for 45 minutes a day, basically 0 cardo. Exact same diet and I lost 4 pounds in those 4 weeks.
What this question needs is a treadmill on a scale in a calorimeter.

Wrong. Look how many retired sprinters pack on the pounds.
The race itself doesn't burn much, but sprint/lifting/xfit training will get you RIPPED and SHREDDED instead of SKINNY FAT like puny distance runners

The faster your run, the more energy you expend per distance due to:
-greater wind resistance
-greater vertical displacement of the body
-greater acceleration of individual body segments
While there may be little difference between running 6:00 and 7:00 per mile, there is a big difference between running 10 and 27 mph.
Once while watching some world-class sprinters train, I was shocked at how profusely they started sweating after a single short sprint. They activate so much muscle that a single short sprint generates a ton of heat.
