Several studies have examined the benefits of post-exercise maltodextrin supplementation in dogs that perform prolonged exercise. Dogs that were given 1.5-2.0 g carbohydrate/ kg body weight post-exercise in the form of maltodextrins were able to recover, on average, about 50% of pre-exercise glycogen stores within 4 hours of exercise and about 85 % of pre-exercise glycogen within 24 hours, while dogs fed but not supplemented recovered less than 40% of their pre-exercise glycogen after 24-hours."

So by feeding ONLY maltodextrin, you get about 85% pre-exercise glycogen in a 24 hour period. Once the other carbs from the food is processed, you will get 100% glycogen replenishment every day.
Nice post, maltodextrins can be bought as pure or powder or something?
