Why aren't elite sprinters out of breath after they race?

You are wrong.

After the 60m women's hurdles last weekend, I noticed that the entire field was completely out of breath.

Wade van Niekirk sometimes gets taken to hospital after a 400m

They all have special asthma meds.

have you ever watched the interview of the winner minutes after the race? they are still out of breath

They are out of breath. They are experienced enough to know that they can breath normally and recover. They know the cameras are watching them so I want to look cool.

200 meters isn't quite enough to get their aerobic system moving, they get there mostly on anerobic energy.

It takes about 30 or 40 seconds of that anaerobic running to get muscle pH down to where it can use a lot of oxygen. Elite sprinters only take about 20 seconds, and they only do one rep.

In the 100, they barely breathe at all.

They're also doing epo with all their hormonal drugs.

The 200 sprint uses approximately 30% aerobic energy.

But what about the strict doping policies USA sprinters must adhere to?

That is meaningless bro science.

Your "aerobic" maximum has nothing to do with stressing yourself aerobically, but with overloading on CO2 from anaerobic respiration. That does not happen in only 20 seconds.

The immediate heart rate increase in a short sprint is due to the skeletal muscle pump speeding blood flow back to the heart, forcing it to beat faster to keep pace.

I'm a physician. Teach me more.

On second read, this is quite the definition of 'bro science.' There are some classics here, like "to get muscle pH down to where it can use a lot of oxygen," and "they barely breathe at all." My (Ivy League) med school physiology lecturers would have a comedic field day with you! Thank you for the entertainment this morning!

It's impossible to get out of breath running for barely 10 seconds

lol, I like how you throw in that you went an 'Ivy League' med school as if somehow that makes your point

more valid or makes you more knowledgeable than someone who went to a non-ivy medical school. If you're trolling, nice work.

I actually agree with you, but there is no point in arguing with the Wigins guy, or most people on this board about physiology.

Tell that to the average american

So they hold their breath?

They look like they are breathing pretty well during a 100 or 200.

Huh?

That is so convoluted.

The tail is wagging the dog if I'm not mistaken.

Beijing 2015 200m clash between Daphne and Elaine. Elaine was glued to the track while there was Daphne up and celebrating, clearly ready for an second race.
