and whatever did ppl do before this relatively new compound was available? :think:
ppl seem to forget WMS, or Karbolyn, or many other designer carb sources that are perfectly sufficient to use intra-training and have never had much feedback about "disturbing the gut" or "cramping", all because there's a shiny new toy out there on the playground now....
but I suppose I will expound on this thread a bit more
the answer to your question OP is ...... there is no answer, on the generic question you pose
one needs to dig a little further, to see what best suits him/her and what other parameters might affect this answer
breezy comes closest to the mark in his post earlier, but i'll carry it a bit further..
whether or not you need carbs intra will depend on more than a few factors, in addition to what kind of "trainer" you are (ie - newb, intermediate, advanced etc) as well as individual goals (ie - training for general health/fitness, training for performance, training for gains, cutting, bulking, etc etc)
1) do you practice solid & fastidious preWO and postWO nutrition?
if so, then the importance or advantage of any intraWO nutrition is negligible (if not potentially even detrimental to goals such as weight loss/body comp etc)
2) what does the rest of your daily nutritional intake look like?
3) how long are you in the gym? actually, let's be very clear about this: most guys who are in the gym for say 2hrs or so, are in there wayyyy too long and have no business being in there even close to that amount of time....this would expose a deficit in knowledge of how to train/conduct your training session to begin with, as far as rest periods/intensity levels/etc etc
if you do train for a longer period of time, and that training is done correctly and not just intermittent sets every 10min or so (while you stand around talking the rest of the time), then yes intraWO carbs may indeed be suitable for you..
so again, summarization: length of training session, as well as intensity, overall workload, experience factor, peri-nutrition strategy and protocol, daily nutrition factors -- all will play a huge part in determining whether or not this practice is suitable for you
this sport is not a cookie-cutter endeavor - thus, there are very, VERY few generalizations that can be made with regard to protocols and all-encompassing standards of employing them
