Dextrose alone or Maltodextrin alone or Both? *Reply w/ experience or research pls*

[Gym_Kitty]

First of all, I want to make sure that I don't need any reply from those who use oats, etc for PWO.

As far as I know, High GI carbs are recommended for PWO shake with Whey, right?

-Fructose : very low-glycemic compared to other sugar, and fructose cannot be used by the body to restore 'muscle glycogen'. -> so No.

-Sucrose(Table sugar) : Disaccharide consisting of one molecule of fructose and one of glucose. So half of the carbs from fructose won't be beneficial. -> so No.

- Lactose(Milk sugar) : GI rating is moderate, higher than fructose but lower than sucrose. Also disaccharide consisting of one molecule of galactose and one of glucose. Galactose can be used by the body to restore 'liver' glycogen, but not 'muscle' glycogen. - so No.


So we're heading to 'Dextrose(Glucose)' and 'Maltodextrin', right?


Now,
Dextrose gets into the system quickly but our body simply can not create glycogen that quickly, so the dextrose is being stored as fat. The rapid raise and the drop in blood sugar and insulin leel will stop the fat burning effect of workouts and putting the body into a 'fat-storing' mode. - "roller coaster'

Then If I use only 'Dextrose' with Whey for PWO, then I drink half at once, then sip it for the next 30mins, would it prevent from storing it as fat'?

Mealwhile, maltodextrin is a complex carb, but its molecular chain is shorter than other complesx carbs. Moreover, it consists of loosely bonded glucose molecules. It doesn't raise blood sugar an dinsuline level quickly, but since it needs to pass through the liver before being utilized, the levels don't drop so quickly. So it remains elevated for a longer period of time. And the bonds are broken between the glucose molecules, the glucose is released at slow enough pace by the liver for the glucose to be fully used for muscle glycogen replacement.

Then Would I get benefits better with just only 'Maltodextrin'?

Or would both of them be better?


Please give me an advice from either your experience/experiments or scientific documents, please.



Thank you in advance.

"There has been some controversy about which type of carbohydrate is best for post exercise glycogen replenishment. Some argue that simple sugars such as dextrose are best after exercise. Others say that drinks with glucose polymers are best. Still others say that there is no need to buy fancy sports drinks and that simply eating a meal high in carbohydrates such as pasta or rice is sufficient. Studies have shown no difference between different types of carbohydrates eaten post exercise and the rate of glycogen replenishment as long as sufficient quantities of carbohydrate are consumed (Burke 1997)."

Galactose is converted into glucose-6-phosphate and enters into glycolysis / the glycolytic pathway so it can restore muscle glycogen.

Thanks. I repped you. But this study is done in 1997. That's like a stone age. Any recent back-ups do you have?

Well there's also this: http://forum.bodybuilding.com/showpo...postcount=3088

from 2006.

Can someone answer to my question though?

based on the situation that I want to take either or both of Dextrose and Maltodextrin for PWO.

Both or better yet, WMS and skip both.

not necessarily

if you want to split hairs then do half dex and half malto, or wms. (I like wms better).

[Gym_Kitty]

Thanks guy. I'll do some more research on this subject. Repping you all

this entire thread is splitting hairs

I already did and did searches on the forums too. I always do when I post any thread. Thanks for the concern, though.
