It was developed for young men doing late summer football practice. It is quite good for that use, or for manual workers doing a combination of cardio and strength work in very hot humid conditions while wearing protective clothing. I've painted houses in these conditions, and it can be hard to drink and keep down enough water; you also lose a lot of salt. Gatorade has salt and sugar in it but at relatively concentrations. You can make your own from scratch, but the bottles are studier and tend to stand up to more abuse
