Where did the air go?

It was my first basketball game tonight.
And I just have one question? (rather my lungs do)

.... where did all the air go???

Sure, I can play volleyball, bellydance, and workout... and I breakout a sweat - but that's it
Get me running up and down a basketball court a couple of times, and BANG I've lost all ability to take air into my lungs. I didn't even get a chance to break a sweat because I couldn't breathe!!!! This is not good news. Its over three hours later and I am still weezing.

Other than the breathing issue, our team did better than I was expecting (although we still lost). We haven't ever played together before, so there's still a lot of kinks to work out, but there's definately talent there!! I can't wait until the next one.
