No matter what kind of exercise you do – whether it’s a run, gym workout or bike ride – you need food and water to fuel the effort and help you recover.
But what’s the best time to eat before and after exercise? Should we sip water or gulp it during a workout? For answers, I spoke with Leslie Bonci, director of sports nutrition at the University of Pittsburgh Medical Center and a certified specialist in sports dietetics. She’s also the author of a new book, “Sports Nutrition for Coaches” (Human Kinetics Publishers, July 2009). Here’s our conversation.
The second issue is someone eats too much. They don’t want to have a problem, so they load up with food, and then their stomach is too full. It’s really a fine line for getting it right.
If people are really embarking on an exercise program and want to prevent that delayed-onset muscle soreness, refueling is part of it. Again, it’s a small amount – a fist-sized quantity. Low-fat chocolate milk works very well. The goal is not a post-exercise meal. It’s really a post-exercise appetizer to help the body recover as quickly as it can. You can do trail mix, or make a peanut butter sandwich. Eat half before and half after.
A. It’s about having carbohydrate with some protein. It’s inexpensive and nonperishable. That’s a big deal for people, depending on the time of day and year. They’re exercising and they don’t want something that will spoil. Peanut butter is an easy thing to keep around.
But nobody can be a camel. If you aren’t taking fluid in you have a risk of heat injury and joint injury, and strength, speed and stamina diminish. This is an important part of any training. Put fluid back into the body during exercise.Q. Should we keep sipping fluids while we’re exercising?
A. How we drink can make a difference in how optimally we hydrate our body. A lot of people sip liquids, but gulping is better. Gulps of fluid leave the stomach more rapidly. It’s important to do this. It seems counterintuitive, it seems like gulping would cause a cramp. People are more likely to have stomach cramps sipping because fluid stays in their gut too long.
When you take more fluid in, gulps as opposed to sips, you have a greater volume of fluid in the stomach. That stimulates the activity of the stretch receptors in the stomach, which then increase intra-gastric pressure and promote faster emptying. This is why gulping is preferred.
