Blood sugar apikes and then drops so less blood glucose.

Less blood to muscle = less oxygen = less atp production = less energy

Umm mind telling me why you say they are shit ?

last time I drank a shake I intraworkout, I booted doing abs at the end.... was a pretty unfortunate situation lol.
if anything I munch the ole fiber one bar or have something simple like a bananer, and drink bcaas throughout every time.

maybe I'll try eating an hour before the gym next time and see if i have more energy.

Which is not anywhere near true rofl. If activity increases, then blood flow in reconditioning organs decreases to compensate for the need for more blood in more metabolically active organs (skeletal muscle in this case).

in regards to OP, feel free to eat whatever u want before lifting. You're probably experiencing a placebo effect, but if you feel like you're doing yourself justice, knock yourself out.

True, I'm curious, would it merely slow down digestion or would it hinder the absorption process

Idk just after squats I get really burnt out. Hard to finish my workout, just feel so dead until I eat something light

I think its mental

On squat day all i care about is hitting my squat reps

After that its half assed accessories

Uhh I wouldn't say think there is a direct hindrance in absorption, so to say. You have ANS-induced changes in more general, "innervate-able" functions such as changes in saliva secretion, rate of peristalsis, opening of sphincters, etc. Those are all things that can be regulated directly.

Chemical fluctuations relative to environment effect rates of absorption, but those localized to digestion aren’t altered too much during physical activity.

They totally are. If blood flow to gut epithelial lining is reduced then you quickly reduce concentration gradients that drive absorptive processes. If blood is not there to carry things away they accumulate
