Carbs Help Marathoners Have Less Pain, More Gain

Carbs Help Marathoners Have Less Pain, More Gain

BOONE, N.C.--Researchers from five universities across the country reported carbohydrates during intense, prolonged exercise may increase the intensity of exercise compared to placebo. In a study appearing in the November Medicine & Science in Sports & Exercise (34, 11:1779-84, 2002) (, approximately 100 marathoners were randomly assigned to receive a carbohydrate or placebo beverage every hour during the 26.2-mile race.

Heart rate, plasma glucose levels and lactate levels were significantly lower in the placebo versus carbohydrate group, while post-race cortisol levels (a sign of high exertion) were higher in the placebo group.

Researchers, led by Alan Utter, Ph.D., from Appalachian State University in Boone, N.C., concluded that the carbohydrate beverages allowed marathoners to run at a higher intensity while experiencing a lower rate of perceived exertion.
