1 - Sports and Energy Drinks: Aspects to Consider

Abstract

Sports and energy drinks are a rapidly growing segment of the beverage industry, marketed by hundreds of different brands. Sports drinks usually contain carbohydrate, electrolytes, minerals, vitamins, and other nutrients, and are marketed as products capable of improving athletic performance by providing hydration and replenishment of electrolytes lost through sweat and carbohydrate during and after intense physical activity. In contrast, energy drinks typically contain stimulants (e.g., caffeine and guarana), which are often combined with amino acids, added sugars, B vitamins, minerals, and other nutrients to form the so-called “energy blend,” to give energy boost, decrease tiredness, and enhance mental alertness. Sales of a range of drinks and sports products have increased exponentially, but there is limited information on important aspects that should be considered. Thus, this chapter proposes an overview of the components, functionality, effectiveness, safety, applicability, and effects of sports and energy drinks on metabolism.
