Sports by Calories
By Katie Arnold

Counting calories, we admit, is really Jenny Craig's gig. But outdoor athletes might take note--to make sure they're getting enough fuel for their pursuits. "You shouldn't get hung up on numbers," says Nancy Clark, director of nutrition services at Sports Medicine Brookline in Brookline, Massachusetts. "But knowing how many calories are burned during different activities can help guide your diet. Your body's like a bank account. You need to balance your food intake with the intensity of the exercise." If you're heading for an hour of rowing, for example, you'll need to take in nearly three times the calories that you would for an hour of sea kayaking. Here's a look at the energy consumed by some favorite summer pursuits, in calories per hour.
