Joshua Naterman Posted November 1, 2012 Share Posted November 1, 2012 There's NO WAY that you're depleting your glycogen stores unless you're running a marathon. One study measured the effect of intense lifting on glycogen stores. The subjects performed 20 sets of squats to failure. That's 20 sets of one of the most demanding exercises TO FAILURE. And then measured muscle glycogen. They found that it was only depleted by 25%. That is 75% of the muscle glycogen stores were still intact. There's no need to eat during your workout session. If you're fatigued just take longer rest times.This is true, but the rate of release of glycogen does slow down as stores get depleted and consuming sugar does help keep energy levels up. I have seen this in every single client I have ever trained, without fail. I believe that part of what is going on is that liver glycogen is being spared to some extent and that glucose from the ingested sugar is supplanting the glucose being released from the liver, but this is a little fuzzy. The extra water that comes with this may play some role, but I notice a massive difference between drinking water alone and drinking water + eating jelly beans or having a small amount of protein + reasonable amount of glucose in the same amount of water.

gravy Posted November 1, 2012 Author Share Posted November 1, 2012 And you can always experiment to figure out what works for you. It's that simple. Link to comment Share on other sites More sharing options...

It's that simple.Very true.Also keep in mind that it takes ~2 weeks for your body to get used to new eating patterns with exercise, so don't think that because you feel weird on day 1 that you won't be feeling ridiculously incredible on day 14. This is most often the case with working out after larger meals and drinking tons of water while working out or running. At first your body doesn't know what to do, which is why you steadily ease into it instead of going full-bore from the start and puking all over your gym or running path Link to comment Share on other sites More sharing options...

Not a single difference was noticed. But it's probably very individual, like alot of other things. Link to comment Share on other sites More sharing options...
Joshua Naterman Posted November 8, 2012 Share Posted November 8, 2012 I think so, and I also think that the state of your glycogen stores is also a huge factor. I rarely work out first thing in the morning, so I don't know if having a few meals first makes a difference in this or not... I hadn't thought about that before. Hmm.For me, I notice that protein + glucose and protein + jelly bellies (specifically) are the two things that work the best for me during a long workout. I don't think it makes much of a difference until 40-50 minutes into the workout but after that it becomes more substantial.There are definitely a few variables that can affect the effectiveness of this strategy.
