The Key to Halftime Refueling

Get better at the sports you play and the life you lead at STACK. Improve your training, nutrition and lifestyle with daily

Halftime allows you to regroup and refuel. Use the time to replenish your body with simple carbs and crucial electrolytes, especially sodium, so you can avoid the dreaded second-half slump.

"During training and competition, it's a good idea for athletes to use sports drinks for [refueling]," says Dr. Kim White, senior scientist at the Gatorade Sports Science Institute. "If you're cramp-prone, it's primarily due to sodium lost through sweat. Sports drinks replace sodium and help prevent dehydration. Also, research shows that taking in a carbohydrate improves sports performance, endurance performance and motor skills."

If you find it difficult to down a sports drink during halftime, Dr. White suggests eating pretzels and drinking water, which rehydrate your body and provide it with needed sodium and carbohydrates.
