well i have some dextrose on order. I'll be mixing my whey with water like always, so adding the dextrose will increase the amount of protein absorbed even more before it passes though my system?
Well, there are many different threories as to what is optimal floating about.
Higher insulin levels promot glycogen storage.. so doing this pwo is desirable.. this would help with recovery and in turn have its own positive effects for on energy levels for the next time you train. Insulin levels will be spiked with the simple carbs and quickly absorbing whey protein in water..
Now, when you train, you basically break down muscle tissue and deplete glycogen stores... so your body is into protein breakdown mode rather than protein synthesis mode AND your glycogen stores are most likely depleted. You need to get it into a positive nitrogen balance and fill up those stores for reasons mentioned above. So now in order to 'rebuild' you need to give the body the raw materials it needs to perform the task. Protein and carbs are needed when the body is in this state. Getting the protein in as soon as you can is a good idea, so the more quickly it's absorbed, the better.. that's where the whey protein is convenient.
The carbs are had to help with the insulin spike and shuttle in the carbs and protein to the hungry stores. Simple carbs are easily absorbed so the nutrient uptake is a lot quicker. Now, carbs don't HAVE to be had immediately post workout, so having them later on in the pwo meal within the hour that follows is fine, because the body will still get its fuel. As they say, comsuming it in one hour is better than waiting three hours.. or six.. or ten..
There's a fear of consuming an excess of carbs pwo.. which can lead to fat storage... I often sip a carb and protein drink while I train rather than all afterwards. There are different ways to go about workout nutrition.. just need to read about and then decide what you may want to try to see what works best for you.
In the end, I think the whey and simple sugars pwo is mostly for convenience.. it has it's positives of course.. and studies show it, but I'm not totally convinced that all these details makes that much of a difference in the end.
