Long Acting Carbohydrates: Too Little Too Late
During a moderate to high intensity workout, your muscles need energy rapidly. Since longer-acting or low-glycemic sugars require more time to pass from the GI tract to the blood, they are not as readily available. As a result, the muscle cells continue to burn glycogen, depleting their finite stores. The racecar analogy best describes the example. You would not want to put fuel in a racecar that was only available after the race was over.
