study nutrition and train for 15 years and you might start to come round to my way of thinking
please expand in full as to my i am wrong, but please dont quote the backs or post nutrition drinks , tell me you own reasoned conclusions ! dont just say your wrong
You're right, that's fair.
First off, I don't care how long you say you've been studying nutrition. You could gain more applicable knowledge after 15 sessions of a college biology or nutrition class than you would in 15 years hanging out at the gym, reading Men's Fitness & the like, and the labels of GNC supplements you buy- all of which constitute "study" to a great many people, I have learned, to my dismay.
Much of what you write in your post is true, so here's the wrong part:
the only time i can see sugars being beneficial is if you had completley depleted your glycogen stores which would be near impossible if your nutrition was good , or if i was taking exogenus insulin and i wanted to force my body into forcing more protien and carbs into the muscle than it normly would
there is no evidence that this makes any difference what so ever , me personaly i just take whey on it own unless im takin insulin
It doesn't matter how "good" your nutrition is, your glycogen stores are depleted from exercise and resistance training (not always completely); "good" nutrition entails eating the proper amount of carbohydrates to replete your glycogen. If your session is short and not intense, and you had something to eat before, it's possible to not dip into glycogen, but everyone in here is an athlete, and their sessions shouldn't be this light (besides, you shouldn't be eating high-GI before a workout anway, that's terrible). Also, blood-sugar levels fall during exercise, and I don't know who told you lifting raises your levels of insulin, but that's wrong, too; it raises your insulin sensitivity, not your insulin in the bloodstream.
And maltodextrin may have a higher glycemic index than dextrose, but it has a lower GI load. In a pure bulking phase, dextrose is probably preferred. Maltodextrin peaks in the system after 90 minutes, not 20-30 minutes, so they are very real differences if you time your nutrient intake, but otherwise, yeah, I was with you here, because that's really the only difference between maltodextrin (corn starch) and dextrose (corn sugar).
But telling athletes not to intake carbs following strength training is the worst possible advice one could give in the Diet forum.
