You post some of the dumbest shit ever. Like seriously. I just got dumber from reading that. In no way are you correct. In fact look up how much exercise it takes to be TRULY glycogen depleted because I'll bet you aren't even close.

Of course your glycogen is never literally depleted. Perhaps you didn't catch this part of my original post:

"I'm sure we all have our own opinions on what "depleted" means to us, and our muscle glycogen is not ever entirely depleted."

I'm implying that my sources (ex., the author of book "9 Out of 10 Climbers Make the Same Mistakes") also realize that you don't ever truly deplete your glycogen stores.

BTW, it's not a dumb question at all. There are very mixed opinions on it, and systems of training (ex., Muscle Logic) are based on it. Many people credit this type of training (draining yourself completely) for their increases in power endurance.

If you have a problem with anything else I posted, you don't have the knowledge to understand its relevance. For example, many people claim that if you deplete your power endurance too much, you'll use bad technique, which makes you susceptible to injury. I was claiming it's not dangerous if, from that point on, you climb routes with sequences involving engrams you've already got well established. Maybe you don't know what engram means. Maybe a stiff prick like you can't tie together two pieces of information.

Other than that, I don't appreciate your attitude, your reply was counterproductive and it doesn't belong in this thread.

I've done my research on glycogen depletion and which athletes should even begin to even use the term when it comes to training and how to avoid it and/or use it as a method of increasing any type of fitness.

Climbing isn't that sport. And I mean NOT EVEN CLOSE to the extreme that your forearms will be absolutely fucking fried hours and hours and hours before getting anywhere close to glycogen depletion especially when climbing something that you "need to have the engrams down" which means a tougher climb but one you know the balance of. Look up how many calories you are burning climbing, it isn't that much at all.

And the term is anaerobic endurance.

You should probably even come up with a half-assed definition of "depleted" instead of none at all because in reality you are just feeling tired from being pumped.

Climb a 5.4 for 5 hours straight and let us know!

Learner, you're a beginner, right? So you have no idea how to even climb yet, right? Learn the basics of climbing movement first. Then once you've actually learned to climb with a modicum of efficiency you can start to worry about how to spare your "glycogen reserves."

At this point in your climbing career you should be sleeping, eating, and breathing The Self-Coached Climber.

Can we just make this the end of the thread? Please!?

You post some of the dumbest shit ever. Like seriously.

If you deplete the Glycogen your body canabalises proteins (muscle) for the energy. If you are full on for over an hour you need some carbs to top up Glycogen, That's why runners use those gel things. A few snacks and keeping Hydrated during your session should sort you out.
Fatigue and Glycogen depletion aren't the same thing neccesarily.
I don't use it climbing but the gels make a noticable difference in recovery when running longer distances.

It is interesting, so why?.

Wow, I've never read a thread full of quite so much misinformation in my life.

Glycogen depletion will not necessarily increase recovery time.

A heavy pump and/or burn is not indicative of glycogen depletion.

It is indicative of lactic acid and other metabolite buildup within a given muscle.

Glycogen depletion can occur rather quickly if somewhat fasted before activity. For example, doing 4-5 sets of high rep bicep curls will likely deplete glycogen stores of the bicep muscles.

Once Glycogen stores are depleted, you will not necessarily burn muscle/proteins.

The process is called glyconeogenesis (proteins are converted to glucose).

In all likelyhood, your body will begin using oxidative pathways to burn fat.

In fact, a given muscle will not burn fat if it still has glucose for fuel.

So, glycogen stores must be depleted under normal circumstances for said muscle to burn fat.

There are certainly others with much more expertise in this, but my understanding is that while there will be some protein used as a source for gluconeogenesis, you're body starts going after your fat stores to a much greater degree before it really starts going after muscle. After all, that's primarily what the fat stores are there for...

That's pretty funny, since, with the rest of your post, you at least double the misinformation.

Um, yeah right.

Lactate does not cause muscle fatigue. That's been shown definitively in controlled experiments.

For 4–5 sets of curls? I'm skeptical, but I'm open to seeing a respectable source for that. Intramuscular glycogen, which would be the main source of glucose for 4–5 sets of biceps curls, is not burned during fasting. Liver glycogen is depleted after a fast, but I wouldn't think that a few sets of curls would be sufficient to mobilize liver glycogen.

If you're doing anaerobic exercise in a fasted state you sure will.

If you're going to throw out a technical term for no good reason, at least get it right. The metabolic process of producing glucose from non-carbohydrate precursors is gluconeogenesis.

If you're doing anaerobic exercise, then the "likelyhood" of that is zero, since it is impossible to fuel anaerobic exercise via aerobic pathways.

That is (a) false and (b) irrelevant to the subject.

And how long would it typically take to replenish some/all gluco?. In other words are all these drinks and so just a con or do they actually actively help you maintain workload?.

If you're actually exercising at an intensity and duration where you're depleting glycogen, then a properly formulated sport drink helps hydration and repletion of glycogen. But we're talking all-day continuous climbing in the heat, not a 3-hour gym workout.
