Most often I hear of the 'puke index' where the individual will over exert themselves and get an over acidic gut. The buffers in the body are not able to neutralize the acidity quick enough and the person will need to rid the acid quickly through vomiting. Over the years I also hear of people having heartburn after workouts. A shot of Apple Cider Vinegar can balance your ph level, but that is not alway on hand, nor does it taste good.
