Sports and Functional Drinks

Dear Colleagues,

Sport drinks often serve two roles during exercise: to replenish body water, and reintegrate electrolytes, carbohydrates and other nutrients to replenish energy after exercise.

One measure of energy drinks is osmolality (carbohydrate content in 100 mL of drink), which can serve as a useful marker in determining whether a given drink is suitable for maintaining adequate hydration in the body. During physical activity, a loss of 2% of body water relative to body weight results in approximately a 20% decrease in body function efficiency. Therefore, the body's hydration status is critical for its functioning. In sports drinks, the osmotic pressure should be adjusted so that it is similar to or lower than the osmotic pressure of the fluids in our bodies, such as blood. Therefore, drinks with an appropriate osmotic pressure can be quickly absorbed from the digestive tract into the bloodstream, ensuring effective hydration of the body.

Sports-related functional drinks are based on carbohydrates and also contain protein, caffeine, vitamins and minerals. The ways in which to balance the ratio of these substances to better adapt to the human body's performance during exercise is worthy of in-depth study.

For this Special Issue, we welcome research on the effects of proportioning in the production of sports drinks on their efficacy, taste, consumer satisfaction, etc.

Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Beverages is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs).
