O/T: The Science of "Muscle Confusion" - Put up or shut up!

[mjw8204]

We see it mentioned all the time -- people offer training tips and advice about taking steps to "confuse the muscles" or "keep the muscles guessing". So many people readily accept this concept, yet NOBODY that brings it up has ever been able to explain it to me when I ask them. Of course, it begs the question, why would you tell someone to do something if you can't explain how it works?

How does a muscle become confused? Describe the physiology of muscle confusion. How does a muscle "guess", and how does this act of "guessing" lead to muscle growth, as many seem to be claim?

Just so there is no confusion (no pun intended) as to what I'm looking for, I specifically want the people that give this type of advice to take a stab at my question. If you are not someone that gives advice involving confusing your muscles, or keeping your muscles guessing, this question does not apply to you, even if you believe you have relevant information. I want the people that advance this kind of information to explain it themselves.

Bro-science or legitimate advice? This is your opportunity to show everyone you aren't talking out of your ass.

its the manipulation of conditioning


most people go OTT with it though and base their workout routine on those principles which is completely absurd


for example; if you've trained in the low reps for a cycle, then you "keep your body guessing" by doing some higher reps for a few weeks, it gives your body a chance to deload.

I think thats where alot of the confusion comes in.

There is no study on this. It would too hard to construct a valid one.

Studies on humans are NOTORIOUSLY hard to construct. That's why so little information is available on diet and exercise.

But...

No positive proof does not imply negativity.

It simply isn't proven scientifically.

If I had to venture a GUESS, I would say that you are stressing different motor units, and the fact that you are NOT as efficient working those pathways gives you a mini "deload".

"Confusion" is sort of muscular anthropomorphism, just semantics.

I would just call it "novel stress".


In one of my Bob Kennedy books (Beef It! I THINK, may have been Hardcore Bodybuilding!), he talks about how Steve Reeves used to do a different workout each day for this purpose. But eventually his body got used to this, and he went back to conventional training.

If you are talking about "P-90X", I think the commercial is totally bull**** in terms of the graphs used. Silly science.

Do you think that your typical BB.com bro that tells people to change their routine every few weeks to "confuse" their muscles are thinking about this in the terms you laid out? Perhaps, but I'm very doubtful of most of them even coming close to providing an intelligible response. Either way, my motivation here is to give them a crack at explaining themselves. This is something that is brought up so often, but explained so little, that it just comes across as a bunch of nonsense that people repeat "just because". It's a popular thing to say and believe, so people just accept it.

I'm not even looking for scientific studies. I'd just like to see a response from these people that demonstrates an understanding of human physiology rather than the bro-logic that is typically parroted around here. Anyone can repeat something they hear a lot. It doesn't make it useful advice.

People tend to miss understand this and since they've miss understood, they've miss applied it.

Anything that will change the leverage of the movement or change the joint angle in the full ROM of the movement will get a different response from the muscle, to what degree I do not know. I'm almost inclined to state that recruitment is recruitment, and its true.

I've done maybe 20 different exercises total in 10 years, and my results speak for myself. Its a complete fallacy that you cannot train the same movements week in and week out, especially when the loading and set/rep volume play a much more important role in hypertrophy. This all really stems to the "It stopped working for me so I'll change up my routine" However if people would pay more attention to progression then they wouldn't have to change **** every 3 weeks.

Ok.. so I bring up two points.. but so what lol

I think it is a legit concept when refering to body builders questions concerning hard gains. "Keep the muscles guessing" change Your routine..
Alot of people stand on high or low rep routines. Some of Us understand what keep the muscles guessing means.

I actually saw after I answered, that I really shouldn't have answered.

But yes, I agree, it is likely just parroting.

Have you seen the "P-90X" commercial I'm talking about? It flat out states "the science of muscle confusion", then offers graphs showing constant gains via this.

I either LOL or get pissed when I see it.

[Mook1e]

I just saw that crap for the first time tonight. Ridiculous.

When your legs adapt to squatting 200 for 5-10 reps, the best way to confuse those quads is not to go to leg press, but to add 5 lbs....or a rep(within reason).

[ThickAsABrick]

People get caught up in the semantics of this, coupled with a general misunderstanding by noobs of what people "likely" mean when they say things like this.
I think of it this way: every once in a while you have a super punishing session with altered intensity techniques (drop sets/supersets/etc) when traditional progression (adding weight or reps) has reached somewhat of a stalemate.
It isn't that I think I shocked a whole lot of growth in one session, but rather I found a way to continue to progress through a means that my body wasn't accustomed to.
I did this the other day by doubling my volume for biceps.
It was shocking!

Edit: it goes (or should) without saying that methods like this are best for people who are more advanced(meaning have a harder time adding weight or reps).

Mjw8204: I will take a shot at qnswering your question.
The terms "confusing and guessing" are wrong interms of what is happening to the muscle but they are terms that the average peorson cna understand and say.
The physiology behind muscle confustion and guessing is simple. as you change the rep range and or load you activate diffrent muscle fiber types. Even new angles of motion activate "unused" muscle fibers.
By activating muscle fibers that are normaly inactivated one can make new gains in mass and stregth.
The part where people get confused is, the body first creates new nerual intervations of the muscle fiber to help adjust to the new load. these new intervation are what create the most strength gains when you fisrt switch programs.
For the laymen the simplist way to explain these events is to call it " confusition and guessing".
the terms of "confustion and guessing" I think where created by trainers trying to explain to the average person why theyneed to change their programs more often. I know when I try to explain to a untrained person what is happening they get glazed eyes and to much time is wasted explaining the terms.
Not saying the average personis stupid but most people don't really want to know the fine details, they jsut want the simplist anwser to a complicated question.
I hope this helps with your question. I joined this board to help with my ability to comunicate in writting. I have no problem explaining the science behind the body and its funtions but I have trouble doing it in writtting.

If you cater to these people the terrorists win.
