Ace asked the Naked Scientists:
   
hello naked scientists!

This is ace, phd student in the US and amateur triathlete.

I am a big fan of your podcast which i listen to, religiously, on a daily basis (and i love your british accents ;-)).

So, I have a sport/physiology related question:

Why is it that, when i run between 90-100% of my VO2max, i have a strange taste of blood at the end, and i often start coughing?

When this happened I spit but there is no blood, just the taste of blood and i start to cough. Note that I have no medical problem and i am in excellent health condition.

thanks very much and thumbs up on your show!
ace

What do you think?

thanks for the info! looks like there are many "theories" outta there. i also heard from some friends who do track that this happens when the air is dry and that this latter might cause the blood capillaries in the throat to burst ( ???)...
anyways... i am egging for the NS's science-backed answer and explanation.
