That's not the same thing. The wooziness that come when working out are accompanied by light headedness, profuse sweating and the shakes. No cramping, but a bit of nausea. It's most often caused by low blood sugar. A condition called Hypoglycemia. The two main causes of Hypoglycemia are a diabetic who takes too much insulin, or an athlete who over exerts themselves and depletes their blood sugar levels too rapidly.
I realize cramps and nausea/vomiting is not the same thing. But consider the possibility that they could be caused by the same thing. If you eat a lot and then work out strenously, and you deprive your stomach muscles of oxygen, those muscles can give up on digestion and then you end up with indigestion.
She did say she was drinking a sports drink, don't those have sugar in them? Well anyway only she knows whether she ate too much prior to working out or got hypoglycemic, or perhaps a different cause altogether. I was just offering up another possible cause. All I'm saying is it's probably a good idea to avoid either one of those scenarios if you're about to take on a strenous workout.
