The takeaway from this is not all carbs are the same. Exercise shifts blood flow away from the GI (Gastrointestional tract) towards the active muscles and lungs.

The quicker and easier those carbs are emptied from the stomach, the quicker those carbs can be used by the active muscles. Also, the more digestion that is required, the greater risk for GI issues.  After digestion comes absorption. For the muscles to continue to perform during long distance activi...

I find that most athletes are not in need of nutrition help to enhance performance but instead, performance is limiting because of nutrition.  You see, there's a big difference between the two. For most age-group athletes, sport nutrition is another confusing topic that is thrown into the mix of understanding how to eat "healthy" on a daily basis. Among the athletes that reach out to me for nutrition help, the majority have some issue with nutrition/fueling/sp...
