What to Drink When You Exercise

The options include sports drinks, energy drinks, and just regular water.

We all know that when we work out, it's important to stay hydrated. Something we may not be so clear on is what exactly we should drink when we exercise.

Ordinary water, of course, is the classic choice. But with store shelves everywhere full of sports drinks, energy drinks, and various flavored and fortified waters, what's an exerciser to do?

Experts say it all depends on your taste -- as well as the length and intensity of your workouts. Here's a look at how the various drinks measure up.

Flavored or Unflavored?

When I'm really thirsty, the only thing that hits the spot is good old H2O -- preferably cold. But that's just me.

Are you someone who will drink more if your drink is flavored (and there are plenty of you out there)? Then you're better off drinking whatever ends up helping you drink more when you exercise. The bottom line is hydration.

Flavored drinks is recommended when fluid replacement is needed during and after exercise to enhance palatability and promote fluid replacement.

And how do you know when fluid replacement is really needed?

Exercising 1.5 hours to three hours is long enough to warrant fluid replacement due to sweat losses. How much sweat is lost influences how much sodium and potassium are lost.

The longer you exercise and the more heavily you sweat, the greater the need for a sports drink to help replace these lost micro nutrients.

A sports drink can do many great things to increase energy levels without the complications of digesting and absorbing a meal.

Sports Drinks and Exercise

Basically, a sports drink offers your body three things it might need before, during, or after vigorous exercise:

• Hydration. People drink about 17 ounces of fluid about two hours before exercise, to promote adequate hydration and allow time for the body to excrete any excess water. During exercise, it is recommended that athletes start drinking early and at regular intervals in order to take in fluids at the rate they're losing them through sweating.
• Fuel. The carbohydrates found in sweetened sports drinks provide energy to help delay fatigue. Lab tests have shown that 6% carbohydrate (14 grams of carbohydrate per 8 ounces of water) is the optimal percentage of carbs for speeding fluid and energy back into the body.
• Electrolytes or Minerals. These are things like sodium, potassium, and chloride that athletes lose through sweat. When water goes out of the body, so do electrolytes. And when the body is losing lots of water (as during exercise), it makes sense that you need to replace electrolytes.
