Actually, just the opposite is true. Your body will absorb water best if you have nothing else in your stomach. Avoid sports drinks and juice, and drink lots of water when you don't have much food in your stomach.
I like to drink quite some juice on my rides, but I avoid them almost completely in hot summer, for good reason.
The body wants a state of homeostasis. If you're losing sugar and salt through exercise and sweat and not replacing it at the same rate the body goes into a stae of confusion. Dousing water into your system can furhter complicate things. You need some salt and sugar...especially if you're not taking in food as well.
Over hydrating causes what is known as "dilutional hyponatremia", or a state of over-diluted blood serum sodium. This is almost as bad as under hydrating. The results are similar: cramping with the added disadvantages of stomach discomfort, bloating, and extra urine output.
The body won't want to take in more water if the blood sugar and sodium levels are depleted. This could be one reason it sits in your stomach.
