Oral electrolytic infusion

Sports drinks, also known as electrolyte drinks, are non-caffeinated functional beverages whose stated purpose is to help athletes replace water, electrolytes, and energy before, during and (especially) after training or competition. Sports drinks are classified primarily by their osmolarity into hypotonic, isotonic, and hypertonic types. According to an investigative report in 2012, the evidence was limited pertaining to the efficacy of use of commercial sports drinks for sports and fitness performance.
