Hydration, yes; 'sports drink', no. One of the big ripoff con jobs, courtesy of Coke, or whoever bottles that crap. From a hydration POV, ANY type of drink other than water is *less* effective than water. From an electrolyte POV, for most people electrolytes are not even an issue, and for those for whom it is, OJ is more than adequate. Or water and an orange. Or a V8. If the original question is comparing the sweating of two diff. people, this is indeed difficult to answer. But for one individual, at a given level of fitness at given ambient conditions, probably the more you sweat the better, as this is now proportional to caloric expenditure, more or less. Sweating 'should' come after getting flushed (pinkish/reddish skin), depending on ambient conditions. Regardless, sufficient exertion should be made so that both occur. People who sweat too easily might not be getting flushed; people who flush easily might stop exercising before sweating. Both are necessary from a tissue perfusion POV (my pet theory). Increased fitness levels will undoubtedly help normalize sweating abnormalities, ie, those who drench themselves or those who don't sweat 'at all'. But, watch yourself if you are abnormal, as the first can have hydration consequences, and the latter hyperthermia consequences. Seek gradual improvement. Of the people who complain about profuse sweating, most are 'round', suggesting poor vascularity/high thermal insulation from fat tissue. This should adjust itself over time. Of course, consult yer doctor, who probably is closer to a coronary than any of us. IMO, sweating is validly related to detoxification (in the legitimate sense, not in the Gary Null sense), but not by releasing lipids through pores, for godsakes. You get salty after exercise, not greasy, beyond the normal sebum. In fact, sebum production and sweat production might be somewhat mutually exclusive. But maybe not... Sweating in and of itself DOES burn a few calories; simply drinking water burns calories; peeing burns calories. Constipation burns calories AND develops good abs. Which suggests a great new diet/weight loss plan, dudnit? Hogg's Drink Yerself Thin/Pee Yerself Thinner/Strain Yerself to Ripped Abs. Send $5 for the details. Corporate accounts welcome.
