- The Benefits of Carbohydrate Loading

- ------------------------------------------------------------------------------

- QUESTION: I'm always reading about marathon runners "loading up" on
- carbohydrates, and having big pasta dinners prior to the day of the race. It
- sounds like lots of fun, especially for those who love pasta. However, what
- effect does this ritual actually have on their athletic ability? Or is it
- just part of the game?
-

- ANSWER: The goal of marathon runners is to have enough fuel stored in their
- systems to last the grueling 26 mile-plus course. As carbohydrates are
- digested, they release glucose, an important energy-producing substance, which
- in turn can be absorbed directly by bodily tissues, or stored in the liver or
- muscles as glycogens--long chains of glucose molecules. Stored fat and liver
- glycogens are effective at powering long periods of low-intensity exertion,
- but fail at sustaining intense exercise for more than a brief amount of time.
- Glycogen stored in the muscles is the most readily available and easily
- metabolized fuel for the marathon runner.
- Complex carbohydrates (pasta, potatoes, or whole wheat bread) are much
- more effective than simple carbohydrates (sugary drinks, candy bars, etc.) in
- helping the body produce and store muscle glycogens; their level at the start
- of a marathon is directly related to the degree of endurance a runner
- possesses. One study has shown that runners with elevated muscle glycogen
- levels were able to maintain their starting pace far longer into an 18.6 mile
- race, and cut an average 11 minutes from their running times. It looks as
- though the athletes are using their knowledge of nutrition, as well as their
- legs, in getting through the race.
