Why are they being sick doing exercise!?

Why do people physically spew!? Xx

[cazzz1975]

a shock to their system I would imagine, their bodies are not used to exercise, plus they are carrying a significant amount of extra weight which wont help.

I am physically pretty fit, but I really pushed myself on a run the other week, the result was that I spewed up my breakfast. I dont know the science behind it but it does happen occassionally when you have pushed your body to its limits...

It must be the same as happens sometimes when people are having heart attacks, the body gets rid of everything it doesn't need, in an effort to save itself.
