Based on the ratio of 2:1 (carbos
rotein) that is used to replenish damage caused by extended aerobic sessions, this would be a good idea to maintain muscle and fuel glycogen stores during/after some competitive athletic events. This 2:1 ratio ideal has brought much success for the acclaimed 'Endurox' and 'Accelerade' products. I know many that use this during long races, especially rowing.
As far as mass retention (anabolic/anti-catabolic properties), it is NOT necessary for simple carbs after a workout. The carbs that you've been consuming throughout the week, the day, etc. should be complex carbs that will indeed guarantee there is no excessive glycogen depletion. A fast absorbing protein is reccommended immediately following an intense resistance training session. We don't need some 'super-carb' crap to magically shuttle the aminos to the muscle. It's a good suggestion for ectomorphs who are trying desperately to gain size, but as for most people you will end up just getting bloated and 'cosmetically' pumped.
As far as I go... I drink about 45 grams of Oryx Goat Whey (predigested pretty much) with water and I may eat a couple slices of Ezekiel cinn-raisin bread with it, or eat a wholesome meal about 45 minutes to an hour later.
