Does muscle memory actually exist?

Pixy ๐Ÿšซ

In a thread about do-overs in the Story Discussion page, mention was made about muscle memory and how it wouldn't work in another body. That got me thinking. Is 'muscle memory' actually a 'thing' or is it simply one's subconscious?

If you were to -somehow- find yourself transposed into another torso, wouldn't you still retain your technical abilities, just not your physical. For example, a thirty year old male shot-putter transposed into the body of a twelve year old ballet dancing girl, would still know how to throw a shot, but be completely unable to actually physically do so. And would this inability cause some sort of mental dissonance, because the brain insists that you can, whilst the body goes "err, no..."

If that's the case, if you were to be placed in a body of same sex, flexibility and similar muscular build, then shouldn't you be able to function as 'normal' because the physiological side can keep up with the mental?

We may one day find out, when brain transplants become reality. If the requisite ethics 'bodies' approve of the experiments/research. Given the pace of current medical advancements, that could well be a discussion that will need to be had in the next fifty or so years.

That's what happens when you get old. You think you can still do something your body no longer can.

Professional sportspersons believe in the concept of muscle memory, that if they practise a specific play often enough, it becomes second nature.

The discussions I have read indicate that 'often enough' is about 10,000 hours. Call it working at it like it's a full time job for five years. That's when you've reached the professional level of doing it.

As for actually practicing it? I've called it sleep working, or zen assembly. When I was on Trim 1, Team 2, at the auto assembly plant, once the job became second nature, you didn't have to think about it at all. There was many a morning they'd start the line at 06:37 and if it was running without any problems, by 06:45 I was zoned out, and the next thing I knew, it was 08:30 and I'd help build 40 cars and have absolutely zero memory about it. Mind you, that was also with zero mistakes, too. Those of us that had worked there for several years used to joke that our bodies knew what to do, and the only reason we needed to engage our minds was when there was a problem, like a screw that was stripped or we saw a paint defect. If you actually had to THINK about what you were doing, you couldn't work nearly as fast as we did.

Couldn't do that when I was driving fork trucks, doing lineside delivery, or unloading trailers, though.

Exactly that.

Muscle memory exists, but it isn't really muscle memory. It is doing something repeatedly until you can do it without thinking.

BUT. The catch is that you can train yourself to do something incorrectly just as easily as you can learn to do so correctly. So those who take such learning seriously tend to concentrate on each movement or response, each step, so as to train themselves to respond not just reflexively but perfectly, each and every time.

I had a golf instructor who said, "Practice doesn't make perfect. Practice makes consistent. Practice it wrong and you learn to do it wrong."

The 10,000 hours is a widely held belief that has little to do with reality.

In reality it really depends on the nervous system of the person. If the nervous system is flexible enough and fast enough, assimilating new skills take way less time. In other words intelligence and age play a huge role in how fast one learns a new skill and how good they could become at it.

A smart person under 25 (while the brain is still forming new cells) doesn't need as long as an average intelligence person over 30 who's brain cells are dying daily, to acquire a high level of skill in some new activity.

For example, a 15-year-old kid could reach a very high level skill in playing golf daily for a year than a 40 year-old playing daily for 5 years or more. Actually it may be impossible for the 40-year-old to ever reach a 'high-level' of skill due to the inability of his brain to form enough new connections.

That doesn't just apply to physical skills but mental skills too. It's a good job James Bond is a fictional character because, based on the number of disciplines at which he's world class, in real life he'd have to be North of 100 ;-)

Not necessarily. We don't like to talk about it, but there are some rare people who are simply... better.

Back in the 90s I knew a woman who was ex-military. Colonel in the Israeli military to be specific. She became a colonel because she spoke at least 17 languages fluently, including Arabic and several dialects, but also knew all the customs and cultural details that were needed to act as a diplomat. She was also a trained sniper with marksman status. She knew four different martial arts and had qualified at the equivalent of master status (eg, black belt).

When I met her, in her mid-thirties, she been out of the military for several years, immigrated to Canada, married, completed a master's degree, and had gotten involved in a medieval group where she was learning fencing, dance, and archery. From what I could see she'd already mastered all three, but she wasn't yet at the point that she considered to be good.

James Bond is fictional and these people are super rare, but they do exist. Just like there are people on the opposite side of the spectrum.

None of those are necessarily 'world class'. You can pick up a new language well enough to hold a basic conversation quite quickly, but speaking it well enough to fool a native takes years.

In every forum I read, and in every dive bar I've went to, someone knows a person just like this. I guess they aren't as rare as we think.

It's also probably fair to say that the people like this probably impress more than one person they meet. So even if they are one in a million, it's not unreasonable to think that they'll each meet and impress thousands of people over their lives.

If 'muscle memory' is intended to mean the muscles responding without a signal from the brain, then I would say NO for a muscle does not contract/move without the brain sending a signal to the muscle.

I define subconscious mind as the person not being aware of the thought processes in the mind. Based on that definition, the subconscious mind could be aware of the signals resulting from what a person sees, hears, or feels, and respond based on past experience without the conscious mind evaluating what needs to be done.

Muscle memory is a thing, but it's a misnomer. It's a nervous system optimization that facilitates the skill being 'memorized'.

When a person does something repeatedly, the brain and spine adapt to the repeated action by creating new nerve pathways and neurone connections to speed up the calculations needed to perform the action. So the 'muscle' memory isn't in the muscles, it's in the nervous system.

Now do-over stories pose a quandary in that regard and it's up to the author to define how things work. Memories and knowledge are encoded in the nervous system via proteins and neurone connections. So by transporting the adult memories to a teen body, those proteins and connections have to be superimposed/injected into the teen's nervous system to make things work and have him/her remember the adults info.

It's up to the author to define whether those pathways of practiced skills are transferred along with proteins and other things required to make the adult memories appear in the teenage brain.

This is close to my understanding. It's really about how neural pathways that fire often accumulate more "insulation" (myelin), thus making those pathways quicker to fire and re-fire, and, of course, making the firing pattern consistent. A pro tennis player doesn't have to think about all their different types of forehands (top spin, slice, drop shot, etc.), and they definitely don't have to "feel" their way through the shot. That would be impossible. They just trigger the swing and it happens.

As has also been suggested, something that is consciously learned is difficult, awkward, and attention and energy intensive when it is being learned, but much less so when it gets "becomes second nature" or "gets handed off to the subconscious" or whatever. Think of a child learning to tie a shoe vs. how it is for you today. Or typing, driving, or doing anything else that you've "mastered."

Of course, even memories themselves involve creating and modifying neural connections in the brain. This is why flash card style studying is so effective. It's not enough to create the memories (memorising material), you also need to practice retrieving the correct memory when given an appropriate stimulus (recalling the memory). You build that pathway by memorising, trying to recall, rememorising, and repeating.

All of which means that from any realistic neuropsychological standpoint any kind of Do-over or brain transfer (eg, cybernetic immortality) would probably require the ability to completely recreate a physical copy of the brain at a molecular level.

None of which means that authors shouldn't tell these stories, of course. All stories have a certain degree of hand-waving. I'm just saying that there's a point you have to stop trying to explain things, because in some situations the more you know the harder it is to explain what you want.

Or to put it more simply, realism does not mean the same thing as realistic.

I'd suppose, "Muscle momory" is kind of prepared spreadsheets for brain-muscle signals for complex actions. Flex X muscle with Y magnitude x 9000 various muscles participating x sensory response x time x resistance (like in water, or in restricting clothes), get expected result. New body, and it all gets screwed.

I actually just had another thought along this line. Those of us who took typing and the kids that now take keyboarding in schools. We don't have to think about things at all when we're using the keyboard, our fingers automatically go to the right keys.

I suppose you could say that our neurons know which way to move our fingers, that are associated with each letter. Otherwise, how could we touch type? I don't even have to have my eyes open to type a sentence, just my fingers on the home row. (And I just typed both of these sentences that way.)

Since you brought up typing -- if you switch the keyboard layout, say from qwerty to dvorak, all indications seems to be that you need about 2 months before you get back to the same typing speed. That is the time it takes to "reprogram" the neurons.

It also works for subconsciousness interpretation too. For example, back in secondary school a long time ago (before this "muscle memory" term enters popular use last decade or so) I took up rowing/sculling for P.E. and the first lesson (aside from how expensive the boats were) is that there are two main points in time for scullers falling into the river:
(1) when they first start out and didn't react fast enough because they need to think first.
(2) when they completely stop consciously thinking about what they are doing, as everything become second nature.
Case (1) we don't laugh at (usually). But it was usually at the 2-month mark (just before term ends) when one of the new pupils did exactly (2) and we all had a good laugh about it when it occurred.

I think that would be fine if all your keyboards were dvorak. That was my problem when I started trying one of them out - I had dvorak at home, but I had to use a qwerty at work, and I couldn't handle it.

It's my understanding the qwerty keyboard came about because manual typewriters simply couldn't keep up with how fast people actually COULD type, and the bars kept getting jammed. I know when I first learned in CLASS in high school - which was AFTER I'd taught myself how to type at home on an electric - I would jam the shit out of those keys.

Of course, keyboards make the whole damned thing a moot point.

Oh hell yes, it is real.

Want a good example? Take somebody that has not been on a bicycle in decades. They will be able to ride again within an hour without any major problems. Because their body remembers how to balance, and will resume without much effort.

I really saw that for myself in 2010. In that year I got back on skis for the first time since 1981. And even though I had gone with my son who had been snowboarding for years, within an hour I was leaving him far behind me and was once again going down expert slopes by the end of the day. Something that when I first learned took me most of the first season to accomplish.

Now the muscles of a "new body" would have to be trained all over again, but the mind would remember how to accomplish what needs to be done. That is all conditioning, not "memory".

And I experienced that also first hand. In 1990 an injury forced me to stop all running and conditioning. However, over 17 years later when I was readying myself to join the military again I resumed running. And while my body was badly out of shape it also remembered what needed to be done, and in about 6 months I was able to push it from running about a half mile to three miles. And eventually to over five miles. It took time and a lot of pain and determination, but my mind already knew what my body was able to accomplish, even if it had not done it in almost 2 decades.

Most physical limits other than sheer endurance are more mental than physical. And even physical limits can be exceeded if one has the determination.

Scientists are beginning to think that even single-cell organisms have "memory", despite having no brain. Google "cellular memory".

https://www.scientificamerican.com/article/can-a-cell-remember/

It may also be possible to physically remove a memory from one single-cell organism and insert it into another. Some researchers already report success with that.

It would therefore not be very surprising to find that more advanced beings might have ways to implant memories in all of us.
