Bananas are great for post workout but I would suggest trying to take them in with a complex carb source or one that will convert to glucose faster than the fructose in the bananas. Bananas are great at replenishing liver glycogen after a workout but it takes longer than glucose to replenish muscle glycogen.
Do you have access to any other carb sources to bring with you? Whole wheat bread, bagels, so on?

Bananas aren't just fructose. In fact they're probably the fruit lowest in fructose...about 1/3 of the actual carb content. Bananas actually contain starch as well.
They're a good choice PWO. Healthier than maltodextrin/glucose, too.

I'm pretty sure Bananas are atleast 1/2 fructose 1/2 dex. As the ripen thats a different story but for when I hope you would be eating them.

From a content of fructose in fruit table its something like out of 15.7 grams of carbs 4.2 glucose 3 fructose and 6.5 sucrose with a total metabolic sugar grams of 6.
Better than I had thought but I would still want something other than just a banana for post workout.

Search for "bananas, raw"
Put in 2 medium bananas
Total carbs: 53.9g
I was actually a bit off...it's closer to only 1/4 fructose:
-sucrose is half fructose, so (5.64/2+11.45)/53.9= 0.2647 or 26.47% fructose.
Sure it changes as they ripen more, just don't go eating brown bananas.
For most people bananas PWO would be fine. If you're a more advanced bodybuilder, then okay, but for most people it should work fine. I'm not trying to be a jerk but a lot of people on the boards (not saying you, OCCfan) hardly even look like they lift and they're worrying about bananas vs. dextrose/maltodextrin PWO.

Wow I wish I had seen that website a while back, I was unaware bananas were as starchy as they are. Thanks for the link man.

Don't forget than protein increases GI as well. I eat basmati rice or cereal after training with a banana and some form of protein.

Actually I think if they're more ripe they'd have more glucose as the starch breaks down.
That's very true...pair with some whey protein and the insulin response is jacked up quite a bit.

The difference in rate of muscle glycogen resynthesis between glucose and sucrose is very small. Thus, even 50% fructose in your postW shake shouldn't be an issue. Having some postW fructose versus none is actually a good thing from the standpoint of anabolic signalling. Also, spiking insulin postW is a practice rooted in myth and misunderstanding - it's simply not necessary, since small rises in insulin are all that's required for maximal net protein synthesis. Granted, it's a different story with large pharmacological doses of insulin - but not with insulin pulses from food. For a more indepth explanation of why insulin spiking isn't necessary, read the opening article here, I specifically address this issue on page 4:
To Bobo's credit, he's seen the holes in the quick carbs thing for a number years now... Does Bobo still post here, or is he too busy traveling the globe in a private jet with the Bobettes?
Anyway, bananas are a great choice for your postW carbs. The whole waxy maize/quick carb thing is hilarious considering that it's only useful if you train to complete glycogen depletion multiple times a day.

Very informative article Alan, and I completely agree with the slow releasing low GI carbs post work out (Being a Bobo client I learned from that.)
Couple questions after reading it if you don't mind. When you said Whole Milk superior for increasing net protein balance is that referring to protein synthesis or just protein uptake into the muscle following training? Also in the "rapid" period of glycogenesis for 30-60 minutes following exercise if insulin isn't what makes it rapid is there another factor that makes it more crucial to take your post workout meal in that "anabolic window" (or is the whole "anabolic window" thing not as important as its made out to be?)
I attempted to word that the best I could so apologies if it does not make sense.
Bobo doesn't really post at all anymore (his FLA sub form is gone as well.) I haven;t really heard anything about/from him since I heard he was getting married.

The whole anabolic window concept was born from research on the posttrained state of overnight-fasted individuals who had no pre or during-workout nutrition. Also, it was focused on expediting speed of glycogenesis - which means jack to trainees who first off don't train to full glycogen depletion, and secondly aren't forced to train those same glycogen-depleted muscles again in the same day.Also in the "rapid" period of glycogenesis for 30-60 minutes following exercise if insulin isn't what makes it rapid is there another factor that makes it more crucial to take your post workout meal in that "anabolic window" (or is the whole "anabolic window" thing not as important as its made out to be?Marriage does change a few things, I'm going on my 9th year of it - and amazingly living to tell about itBobo doesn't really post at all anymore (his FLA sub form is gone as well.)

Thanks for the insight, very helpful learning why certain techniques are used and the reasoning behind it. Its very interesting that the whole anabolic "window" is over emphasized quite a bit (but it really makes sense especially when I think about all the CKD stuff when its really crucial then to take in high GI liquid carbs directly after the depletion workout at the start of the carb up.)

Bananas are like my favourite pre and post workout foods. They're great. Then again I don't buy all this take-80g-sugar-give-yourself-type-two-diabetes post workout cocktail stuff so I might not be the most appropriate person to listen to if you believe spiking your insulin post-workout is important.
