Does Gatorade do what it claims?

It seems easy enough. It contains electrolytes to keep your body hydrated but, does it actually work? It’s my understanding that you need sodium ions to keep your body from turning the water you need to exercise into urine. So, it makes sense that gatorade could easily give a good amount of sodium to do this.

However, it seems like gatorade is more of a soft drink now-a-days, just like soda. Maybe it worked back when they first invented it but I’m not sure about now.

Does anyone have an opinion or better yet some facts about this?
