(8)One way to decrease the risk of exercise-related gastrointestinal (GI) problems is to:

 

 

 

Avoid dairy products prior to exercise

 

Consume high-fructose beverages one hour prior to exercise to enhance blood glucose levels

 

Consume high fiber foods one hour pre-exercise to slow carbohydrate absorption and maximize blood glucose prior to exercise
