The higher the molecular weight of a carbohydrate, the lower it’s osmolality. The lower the molecular weight of a carbohydrate, the higher it’s osmolality. So, a carbohydrate’s molecular weight varies inversely to its osmolality. Knowing this, you can begin to more closely appreciate the difference between HMW carbohydrates and Dextrose. The molecular weight of the typical HMW carbohydrate that is marketed today has a molecular weight of 500,000-700,000. The molecular weight of Dextrose is approximately 180. (11) This stat helps quantify the difference between the two carb sources.
The Osmolality of said HMW carbohydrate is 11 mOsm/kg in a 5% solution., which is considerably lower than the osmolality of blood at 300 mOsm/kg. With an osmolality that low, the HMW carbohydrate is extremely hypotonic, and we know that the more hypotonic a solution is, the quicker it passes through the stomach into the small intestine.(11) This means that the world of carbohydrates, the HMW carbohydrate is a Ferrari Enzo, and Dextrose is your mother’s Buick Skylark.
And again none of that means shit:icon_lol:
In fact, one popular HMW carbohydrate drink has been shown to pass through the stomach 80% faster than dextrose, allowing restoration of glycogen 70% faster than any other carbohydrate.(13) How would you like to like to start rebuilding muscle 70% sooner than you already are after a workout? One study on the subject showed that the mean glycogen synthesis rate was significantly higher for a HMW carbohydrate drink compared to a glucose drink for 2 hours after ingestion, with the scientists coming to the conclusion that "the osmolality of the carbohydrate drink may influence the rate of resynthesis of glycogen in muscle after its depletion by exercise."(6) What the scientists are saying can be paraphrased as "a HMW carbohydrate will get to your muscles faster than the carbohydrate you’re using now." These studies showed that blood sugar levels and insulin levels were not statistically significantly different the HMW carbohydrate and the glucose. So, despite being a complex carbohydrate, compared to the sugary Dextrose, the HMW carbohydrate was still raising insulin at about the same level as Dextrose. So, at this point, what we’re dealing with is something that powers through the stomach, leaving you with no bloated feeling, reaching the point of digestion at mach speeds, reaches the blood stream as fast as Dextrose, but restores glycogen 70% faster. Sounds too good to be true? It gets better.
In the long road of recovery that means nothing. The studies they used for that can be beat to death on Avant and other boards. Whoopy it raises insulin. Why is that needed? The body takes care of that premise on its own PWO.
What this all leads towards is that the Osmolality of HMW carbohydrates can potentially speed up the rate of glycogen synthesis post workout, as well as increase the uptake of vital nutrients added to the HMW carbohydrate drink. That’s right, all the stuff you’ve been taking after your workout, in the hopes of getting it to the muscle, can be sucked up right along with the HMW carbohydrate, faster than ever before. The only problem is, any amino based nutrient (protein, amino acids, creatine, etc.) has a much lower molecular weight than the HMW carbohydrate, so when adding other nutrients you must consider the effect those nutrients will have on the total molecular weight of the mix. So, at least in theory, too much protein, creatine, and other nutrients can take away some of its benefits.
It won't increase the uptake of nutrients anymore so than oatmeal would. :icon_lol:
For this reason, it is my belief that added amino based nutrients should be kept to a minimum during ingestion of a HMW carbohydrate drink. My current recommendations for a 200lb bodybuilder are 75g of a HMW carbohydrate mixed with 5g creatine, 8g L-leucine, and 5-10g of BCAA’s. Since we’re trying to keep extra nutrients to a minimum, we are focusing on select nutrients that give us the most "bang for our buck." L-leucine has been shown in studies to be the specific amino acid to "switch on" protein synthesis. And all of the Branched Chain Amino Acids (BCAA’s) have been shown to be preferentially taken up by skeletal muscle. Creatine has been shown in many studies to provide many benefits to bodybuilders. This means that the "best" amino acids will be available as quickly as possible to trigger muscle growth, and decrease catabolism.
That many carbs for what reason? What are they eating the rest of the day? What is their fat intake at? I love it when people can't defend their point so they copy and paste other peoples work. Show me some studies that prove your side and show them to me in your words. It's not that hard. But this supplement add is hardly a rebuttal.
This meal should be followed approximately 15-30min later with a meal containing protein and complex carbohydrates, preferably a fast digesting liquid protein such as a whey isolate, and some complex carbohydrates.
I like that meal, should have been the first meal PWO though:icon_chee
If you understand the make up of your muscle mass, you will learn that there is much more to the muscle than just contractile tissue. A large portion of your muscle mass area is made up of things besides muscle. There is water, glycogen, minerals, blood vessels, capillaries, etc., etc. By using these HMW carbohydrate powders, you can quickly draw the carbohydrate up into your muscles, along with water, and the cell volumizing nutrients you take along with it. With the faster glycogen restoration, you can decrease catabolism after a workout, and speed up the potential for synthesizing protein as new muscle. In plain English, the result is more muscle.
It doesn't restore it any faster. Type of GI PWO doesn't matter. Same study, read it, engrain it. It's correct.
Normally I wouldn't want to cram this type of jargon down peoples throats, it can get a bit comfusing to some. But apparently it is the thing to do here. I dont wanting anybody laughing at me, it might hurt my feelings! I didn't go anywhere Vedic, Stick to the topic next time and quit trying to toot your own horn.
I hope this helps those in question.
