For those who have a high carb diet and are interested in glycogen replenishment post workout, I found the following which may be useful. It suggests that consuming huge quantities of carbs post-workout, as some people do, may not be necessary.

Glycogen depletion;

Very high intensity, intermittent exercise, such as resistance training or half-court basketball, can cause substantial depletion of muscle glycogen (decreases of 20 to 60%) with relatively few sets of exercise (low workloads).
The rate of carbohydrate replenishment;

Optimal carbohydrate intake replenishes glycogen stores at about 5 to 7% per hour. Even under the best of circumstances, it takes at least 20 hours to reestablish glycogen stores following glycogen-depleting exercise.
The suggested quantity of carbohydrate for glycogen replenishment;

How much carbohydrate you ingest has a significant effect on the rate of glycogen synthesis. Ivy (1998) found that 1.0 – 1.5 grams of carbohydrate per kg bodyweight is the ideal amount of carbohydrate to ingest to maximize recovery. In fact, carbohydrate supplementation in excess of 1.0 grams per kg bodyweight has not been found to further enhance glycogen resynthesis rates. Blom et al. (1987 in Ivy, 1998) found that when comparing the ingestion of 1.4, 0.7, and 0.35 grams of glucose/kg bodyweight immediately after and at two hour intervals following exercise, there were no differences in glycogen resynthesis rates between 1.4 and 0.7 gram concentrations. However, the rate of glycogen resysnthesis was reduced by 50% with the use of 0.35 grams of glucose/kg bodyweight.
The optimal strategy for glycogen replenishment;

Consume between 0.7 and 1g of high-to-moderate glycemic carbohydrate per kg of body mass immediately post workout, and then again every two hours until eating a large, high carbohydrate meal.
So, in example, if you weigh 70kg, consume between 49 and 70g of carbs post workout, and then again every two hours until a large carbohydrate meal is eaten. Consuming more carbs than this in the post workout period it appears is unlikely to afford you any extra benefit in terms of glycogen replenishment.

Of course not everyone follows a procedure of glycogen replenishment, and such an approach is incompatable with those on a low carb diet.
