Abstract

IntroductionSport drinks are beverages aimed at rehydrating the body, restoring theelectrolytes (Na, K, Mg, Ca, Cl, P) and energy reinstatement (carbohydrates andother nutrients). As is well established in research5, the concentration of thesesubstances decreases as a result of sustained strain and, in some cases, these caneven finish and alter the organic functionality1,7. Sport drinks were born for thepurpose of performance and are classified based on their concentration/litre inisotonic beverages (with an electrolytic composition more or less similar to bodyfluids [about 300 mOsm /L] with medium – rapid assimilation), hypotonicbeverage (with an electrolytic composition lower than that of the body fluid, atrapid assimilation) and hypertonic beverages (with an electrolytic compositiongreater than the body fluid, with a slower assimilation to those mentionedpreviously)1. The first drinks to be widely marketed were those based on mineralsalts (iso – hypo – hypertonic). Then, soft drinks containing high concentrationsmore or less of carbohydrates, proteins, lactate polymers, maltodextrins andcaffeine conquered the global market; We should note that in Italy alone there aremore than ten industries in this sector. Energy drinks ( literally beverages that giveenergy) are drinks of recent ideation and represent a subset of sports drinks andconsist of soft drinks containing concentrations (single or in combination) more orless high in caffeine, B vitamins, herbs, guaranina, taurine, ginseng, inositol,carnitine, creatine, glucuronolactone, Ginkgo biloba, and others.The objective of this study was to conduct bibliographic research on sportsdrinks in order to obtain useful information and, accordingly, try to clarify someaspects concerning the physiological effects of the substances mentioned above,collect the scientific evidence, any contraindications and their optimal use.
