Why do you people use fruit PWO? It is time for a change

Let me first give u the definition of fructose and what exactly it does

Referring to the three ways the body uses glucose, assuming that blood glucose levels are adequate, the glucose will then be stored as glycogen. Muscle does not have the necessary enzymes to synthesize fructose into glycogen; therefore the liver converts this fructose into liver glycogen. It would only take three, 8-ounce glasses of orange juice to fully replenish liver glycogen stores. Since the liver is responsible for supplying energy to the entire body, once its stores are full, a rate limiting enzyme in glucose metabolism, which is responsible for signaling the body to store glucose as glycogen or convert it to fat (phosphofructokinase), signals the body that all stores are full. If the glycogen stores are signaled as full, then the third way our body uses excess glucose is to convert it to fatty acids and store as adipose tissue. In essence, fruit sugar is easily converted to fat.

Many may be asking why then is fruit low on the glycemic index? If it does not cause a sudden release of insulin, then how could it ever be a poor food choice? Once the fructose (fruit sugar) enters the liver and liver glycogen is[ already full, then it cannot be used by the muscles for glycogen or energy production.

It is converted to fat and released back into the bloodstream to be stored as adipose tissue. The low glycemic response is based on the fact that fructose leaves the liver as fat, and fat does not raise insulin levels.

Basically.. fructose does absolute crap when it comes to muscle building and restoring muscle glycogen.. once the liver glycogen is filled ur body cant use it and it is stored as fat

Now a study that compares fructose compared to glucose in muscle glycogen recovery post workout

Muscle glycogen recovery after exercise during glucose and fructose intake monitored by 13C-NMR

Van Den Bergh, Adrianus J., Sibrand Houtman, Arend Heerschap, Nancy J. Rehrer, Hendrikus J. Van Den Boogert, Berend Oeseburg, and Maria T. E. Hopman. Muscle glycogen recovery after exercise during glucose and fructose intake monitored by 13C-NMR. J. Appl. Physiol. 81(4): 1495-1500, 1996.---The purpose of this study was to examine muscle glycogen recovery with glucose feeding (GF) compared with fructose feeding (FF) during the first 8 h after partial glycogen depletion by using 13C-nuclear magnetic resonance (NMR) on a clinical 1.5-T NMR system. After measurement of the glycogen concentration of the vastus lateralis (VL) muscle in seven male subjects, glycogen stores of the VL were depleted by bicycle exercise. During 8 h after completion of exercise, subjects were orally given either GF or FF while the glycogen content of the VL was monitored by 13C-NMR spectroscopy every second hour. The muscular glycogen concentration was expressed as a percentage of the glycogen concentration measured before exercise. The glycogen recovery rate during GF (4.2 ? 0.2%/h) was significantly higher (P < 0.05) compared with values during FF (2.2 ? 0.3%/h). This study shows that 1) muscle glycogen levels are perceptible by 13C-NMR spectroscopy at 1.5 T and 2) the glycogen restoration rate is higher after GF compared with after FF.

Glucose murdered fructose.. my question to you all is, why do you continue to use fruit post workout when something like dextrose is optimal and cheaper than fruit? It is also readily available

I use oats

Mr.Hombre · 10-09-2007, 07:06 PM

replenishing muscle glycogen is the primary concern. however, the amount of liver glycogen that's tapped into is proportional to the intensity of workouts. so, it's a good idea to have some (about 1/4 or so) of your post workout carbs target liver glycogen

then what would u suggest for an easy carb source in a PWO shake?

i currently use 30g of carbs from a banana and 25g of carbs from dex

it doesnt get much easier than dextrose.. banana isnt to bad.. its about half glucose half fructose with a little bit of sucrose isnt there

Probably because they came into the nutrition section and listened to advice from one of the threads that basically goes against everything we have ever learned about how to eat for bodybuilding purposes. Then it became a cult-like following of rebels and renegades.

Sixpack · 10-09-2007, 07:16 PM

U don't need fast digesting carbs Postworkout, I have a regular meal afterwards and it has worked great. You will spike insulin no matter what. MY gains have always been leaner taking in complex carbs instead of simple carbs. Read up on the sticky up top on postworkout nutrition by Alan Aragon.

BlueFenix13S · 10-09-2007, 07:19 PM

If I have fruit PWO, it's bananas, which as far as I know have a higher % of glucose and sucrose than other fruits.

well i dont have time to eat WHOLE foods PWO.. so what would u suggest blending with my whey isolate?

Haha Thanks for clarifying

. Yea I think SOME fructose is beneficial, but it is not the best for the majority of PWO carbs. For those than can take dex/malto/WMS without fat gains (i.e. mesos and ectos), that's the best bet, for endos, complex starchy carbs and maybe a LITTLE bit of high GI carbs is best. The amount of carbohydrate taken in is more important for protein synthesis than the type. If we are talking glycogen re-synthesis, then I agree with you in that dex/malto/wms is the winner.

i agree with u 100%

fructose is not useless and is important.. i often have an apple and honey for breakfast to replenish liver glycogen i just find it useless for postworkout and find there are much better options as fructose cannot replenish muscle glycogen which is key pwo

i have used oats dextrose and WMS.. personally there isnt much a different imo.. though wms and dextrose may be the "optimal" choice it wont make a huge difference, if any, in the overall picture

You didn't get sh**ty genetics like me then lol (endo torso from my dad, ecto limbs from my mom). I went with malto for a bit, but too much fat gain, so I have milk, honey, and oats or a bagel now.

dextrose bloats me quite a bit.. but i like it a lot

currently my pwo shake is
12 oz milk
one scoop whey
75 grams wms
10 grams leucine

im gonna switch back to dextrose though after the wms is out

well.. there are no bagels down here in the cafe and i dont really feel like going out to buy any.. to tell u the truth.. i rather just blend something in my magic bullet while i hop in the shower and then pick up my cup and go to class.. it works 100x easier..

but if i do decide to pick up a bagel.. wouldnt one be about 50g of carbs or so? and does it matter what flavor is it (cinnamon raisin, white, whole wheat)

I'm surprised the cafeteria doesn't have bagels. You have Ezekiel bread don't you? Just bring some to the gym.

As long as it's got enough carbs, get whatever tastes best. I'm a fan of cinnamon raisin.
