We are all aware of the importance of hydration when it comes to sport and improving performance. Exercise scientists and dieticians have invested extensive research in this area. Sports drinks are designed to provide fluid and carbohydrate that is easily absorbed in the small intestine.
Sports drinks contain carbohydrates, electrolytes, flavor and other ingredients.
Carbohydrates provide fuel for muscles. When carbohydrate is present in the drink at a concentration below 8%, which is rapidly absorbed by the body. If the concentration exceeds 8%, water absorption is slower. Carbohydrates may be added to sports drinks in glucose, glucose polymers, sucrose, fructose or form.
Sodium, potassium and magnesium are sometimes added to sports drinks and are called electrolytes. The addition of sodium which is said to stimulate the absorption of carbohydrates and water from the small intestine. Most sports drinks contain 10-25mmol / L sodium which makes you thirsty you are encouraged to drink more.
Most athletes only replace half the fluid lost during the sport, so it is important that sports drinks are tasty to encourage athletes to drink more.
Some manufacturers of sports drinks also add vitamins, minerals, proteins, herbs, and sometimes even caffeine. Be wary of big promises.
The best drink for you depends on your personal preferences. Most manufacturers tend to follow the basic formula, which actually reduces to taste. The more you like the taste of your drink instead of drinking and more important to replace fluids.
