Kids Need To Drink Fluids Before, During and After Sports

Kids Should Drink On Schedule, Not Just When Thirsty

Choosing the right fluids

  • Sports Drinks Are Best. The best source of fluid to hydrate the body - especially during intense exercise in the heat - is a sports drink. Your child will be more likely to drink the fluids she needs if you give her a flavored sports drink that tastes good and stimulates thirst. While sports drinks are absorbed just as quickly, and promote optimal cardiovascular function and temperature regulation as well as plain water, they offer the following advantages: 
    • Sports drinks contain glucose and sodium, which increase the rate of fluid absorption by the small intestine;
    • By providing carbohydrates for working muscles, sports drinks improve performance during both prolonged exercise (lasting an hour or more) and when exercising for an hour several times a day; and
    • They encourage drinking by "turning on" the thirst mechanism (research has shown that children stay better hydrated when drinking sports drinks compared to plain water). 
  • For optimal absorption and performance, look for sports drinks that contain: 
    • 4 to 8% carbohydrate (10 to 18 grams per 8 ounces)
    • About 36 to 77 calories per 8 ounces. 
  • Because most sports drinks contain 5 to 8% carbohydrates, it's a matter of personal preference: have your child try several sports drinks to find the one that works best for her. Note, however, that research has shown that children and those in early adolescence prefer grape-flavored sports drinks to apple or orange.
  • Avoid sugary or carbonated beverages.  Beverages that contain more than 10% carbohydrate (about 96 or more calories per 8 ounces), such as fruit juices, or energy drinks, or are high in fructose, like carbonated soft drinks, should be avoided. They are absorbed more slowly and can causes stomach cramps, nausea, bloating and diarrhea.
  • Avoid caffeinated beverages. Children should avoid drinking ice tea or soft drinks containing caffeine because they are diuretics (promote urination), and because the potential side effects - agitation, nausea, muscle tremors, palpitations and headaches - work against peak athletic performance.  Energy drinks should NOT be used for hydration.

* Note to parents of water and winter sport athletes. Don't be lulled into thinking your child doesn't have as great a need to replace fluids as other athletes. A swimmer still loses body water through sweat in the pool, and can become dehydrated by sitting on the pool deck (a hot, humid environment) between exercise sessions or during a long meet (they always are!). Winter sports athletes (figure skaters, hockey players, skiers) also may not realize the importance of fluid replacement because they practice and play in a cool or cold environment, and because their clothing and equipment reduces the ability of the body to cool itself.
