Athletes have many factors to consider when it comes to improving their performance, and one of these critical aspects is maintaining proper water levels, or hydration. Water makes up about 60 percent of the human body, and is critical to transport nutrients and maintain body temperature, among other physiological processes.
Numerous beverages and sports drinks have been promoted as being beneficial for fluid replacement or retention in athletes. For moderate exercise (less than two hours), water should be sufficient to meet hydration needs. For longer periods, sports beverages, drinks, or gels can help replace electrolytes lost in sweat. Some products are also recommended after exercise to replace the proteins and carbohydrates consumed. It is important for athletes to have proper hydration and nutrient levels before, during, and after exercise for both performance and overall health, and specialized products can help fulfill these needs.
