Not really
it's not something the average trainee should actively seek. Resistance training alone doesn't deplete glycogen stores to a sufficient amount to really garner a need
I also don't know if sugar ingestion inhibits GH secretion. It could maybe make sense through downregulating ghrelin post-prandially, but then any nutrient would do that so not sure.
However, even if it's true, it doesn't matter. The GH rise post exercise doesn't do much in the way of promoting protein synth and total hypertrophy.
Also, nah, for "best results" you don't need to eat within 30 minutes. Pretty sure that was the whole point of the meta-analysis put together by Brad and Alan.. to crush that thought process of an anabolic window. You have a conclusive couple of hours at least. Oh, and btw, glycogen depletion doesn't impede protein synthesis as much as you believe, at least using p70s6k as a proxy in your measurement.
my thoughts had pretty much nothing to do with protein sythesis specifically. I didn't even give it a second thought that it would impede protein sythesis tbh
also, read my other comment. You're right about the 30 minute thing. Like mentioned, hitting your macros seems to be what's important. Also, I never read or heard about the meta-analysis you mentioned. I do little research on this sort of thing but it's certainly giving me incentive to devote time to actually study it. I find it fascinating. The CSCS book I have also suggests a couple hour window if you read between the lines
Lastly, the CSCS book specifically says resistance training puts a high demand on the muscles and their glycogen stores (I understand there are other factors to take into consideration in this though, such as total work performed, time, and intensity relative to VO2 max) so I'm going to believe the text book unless you have something concrete to say otherwise. Unless my 5AM reading was backwards and I remember it wrong (possible, as it was 5AM...)
As a side question, why would monosaccharides or disaccharides inhibit GH? Would polysaccharides also inhibit it? And since we're on the topic, why would any carb inhibit GH when your body needs carbs to begin with? seems counter productive for such an efficient system.
