Big, Deep Breath

[kieroneil]

This is more of a curiosity than anything else...

I've noticed that when I train a lot or after I do a big race I'll occasionally, almost randomly, take a big, deep breath.

It's very odd because I'll just be sitting at my desk and right in the middle of normal breathing it will happen.

It's almost like my body is saying "OK, we need a lot more oxygen right now."

My theory is that in a heavy training/racing period that my core metabolism is so high that normal breathing doesn't satisfy my oxygen needs so occasionally it supplements it with a big breath.

Has anyone else experienced this or know the cause?

Thanks,
