A sports drink is a beverage designed to help athletes rehydrate, as well as replenish electrolytes, carbohydrates, and other nutrients, which can be depleted after training or competition. A drink, or beverage, is a Liquid specifically prepared for Human consumption A sportsperson ( British and American English) or athlete (principally American English is any person who participates regularly in a Sport. An electrolyte is any substance containing free Ions that behaves as an electrically conductive medium Carbohydrates (from ' Hydrates of Carbon ' or saccharides ( Greek σάκχαρον meaning " Sugar " are the most A nutrient is food or chemicals that an organism needs to live and grow or a substance used in an organism's metabolism which must be taken in from its environment Electrolyte replacement promotes proper rehydration, which is important in delaying the onset of fatigue during exercise. As the primary fuel utilized by exercising muscle, carbohydrates are important in maintaining exercise and sport performance. [1][2]

Overconsumption
Companies who market sports drinks point out the fact that plain water, despite its association with good health, can actually be toxic if consumed in large amounts (cf. water intoxication). Water intoxication (also known as hyperhydration or water poisoning) is a potentially fatal disturbance in Brain functions that results when the This can happen because overconsumption of water reduces levels of electrolytes such as sodium and potassium in the body by dilution, interfering with the nervous system.
While overconsumption of water is the primary cause, a number of other factors may also play a role in the development of water intoxification. Although sports drinks contribute sodium to the blood, it is important to note that sodium concentration of sports drinks is lower than that of the blood, so zealous overdrinking of sports drinks could also eventually result in dilution of blood sodium concentration.

Categories of sports drinks
Sports drinks can be split into three major types. [4]
-
- Isotonic sports drinks contain proportions of water and other nutrients similar to the human body, and typically are six to eight percent sugar. Tonicity is a measure of blood capacity or effective osmolality in cell Biology.
- Hypertonic sports drinks contain a lesser proportion of water, and a greater proportion of sugar, than the human body. Tonicity is a measure of blood capacity or effective osmolality in cell Biology.
- Hypotonic sports drinks contain a greater proportion of water, and a lesser proportion of sugar, than the human body. Tonicity is a measure of blood capacity or effective osmolality in cell Biology.
Most sports drinks are isotonic, and have between 13 and 19 grams sugar per an eight ounce serving.
