When you exert yourself, you can trigger what is called a "vaso/vagel" response. What this is, is the irritation of the Vagus nerve. It controls your heart rate and B.P. when stimulated, it will/can cause a drop in heart rate and B.P.
Now, your stomach requires a B.P of roughly 90/60 to be supplied with blood and to make the digestive juices required to process food. If your B.P drops below this level, it will eject everything out of the stomach. See where I'm going with this ? I'm going to bet that you also feel dizzy and light headed prior to throwing up... Symptoms of a sudden drop in B.P. to remedy this you can do a couple of things. DO NOT hold your breath when straining, this is a common trigger. If it happens anyway, lay down on the floor and put your feet up resting higher than your head, this will drain blood from your legs into your trunk, increasing your B.P. if you think you might get sick, do this next to a garbage can, but realize that if you drop your B.P enough, and you are standing, you stand a good chance of doming your melon on a piece of gym equipment, and might need me to take you to the hospital in the waaambulance.
