Summary/Abstract: Three main factors are usually associated with the reduction of sports performance due to dehydration: temperature increase of the body, carbohydrate depletion, and alteration of cardiovascular functions. Plain water is the universal hydration liquid; however, in sports, it is not sufficient. On a common acceptance, the presence of electrolytes in order to maintain plasma osmolality is mandatory. In this respect, there is a rich market of commercial ready-to-drink beverages or powders intended for dissolution in water with attractive colour and sweet-acidic taste (usually potentiated with synthetic sweeteners, colourants, and acidifiers) promising not only good hydration but also a better performance. This is enssured by adding vitamins, other minerals (Ca, Mg, K) and other ingredients besides glucose and sodium. Besides necessary ingredients enssuring an isotonic medium, the presence of additives in commercial sports drinks raises legitimate concerns. In addition, the high price of the most has to be also considered when deciding on the best (re)hydration choice. Considering these, the addressed question discussed was the efficiency of commercially available products compared to homemade mixtures containing water, fruit juice, salt, and sugar.
