From Wikipedia's description of muscle memory: > When a movement is repeated over time, a long-term muscle memory is created for that task, eventually allowing it to be performed without conscious effort. But this article is about enhanced muscle recovery and volume, not about motor learning. I wonder if that's an abuse of the term "muscle memory" or just a different sense. I'm not finding that sense used in a quick search. But the term is also used in the review paper that this article is about, so apparently it has a specialized sense in that discipline. According to Wikipedia muscle memory as retained skills isn't about muscle fibers, but neurons. https://en.wikipedia.org/wiki/Muscle_memory https://en.wikipedia.org/wiki/Muscle_memory

Developing muscle strength is mostly about training and growing the nerves in your muscles to engage more muscle cells when they fire. If your muscles could fire maximally they'd be strong enough to rip tendon from bone.

    And partially incorrect. This is indeed the case for the first few weeks of strength training. In the beginning your body learns to recruit and better utilize the existing muscles you have. But after that the long and slow process of building new muscle mass starts. The CNS adaptation( i.e. the first part) never goes away. That's the reason why if you have trained in the past for at least a couple months and now you restart your training your new starting weights will be higher than your old ones.

  While your second sentence is definitely true, I disagree with your first. Developing muscle strength is partially caused by training your nerves to better engage your muscle fibers; however, simply adding fibers aka raw muscle mass is the other main component of gaining strength. I would argue it's the predominant factor.

    You're both right. Improved muscle fiber recruitment is the primary way beginners gain strength. This is a fairly fast process, but plateaus off quickly. After the so-called "noob gains" are through, growing more muscle is the primary way to gain strength.

      My knowledge on the subject is a bit out of date as I'm not in a serious training for more than a decade, but if I remember correctly explanation from my coach there're 3 main aspects of strength: nerve paths to activate the muscle fibers, the volume of muscle cells (when you get "big muscles" you actually don't increase significantly the number of cells, but their volume), and the capability of muscle cells to use and store glucose from the bloodstream (cellular uptake, which is also increased by regular training).

        This is largely true. Though, as with anything in the body, the entire system reacts. Bones will change density, the circulatory system also changes in relation to the increased mass, the cerebellum will re-wire due to the increased muscle mass and usage cases, the reproductive systems may change depending on many factors, the pancreas will change it's output of glycogen, etc. When it comes down to building muscle mass and 'dexterity', the physiology is fairly well understood. For most athletes today the major issues are in repair/strain and consistency. AKA: Sleep well, eat well, train well, in that order. It is theorized that a lot of the recent gains in MLB pitching are due to improved tendon repair chemical therapies and traditional steroids that focus on bulk (no data here, I think I read it on 538 a few years back)

  If I'm not mistaken, muscle fibers can only fire maximally--a muscle fiber either fires (maximally) or it doesn't fire. Isn't muscle fiber recruitment what differentiates delicate, precise motions from gross, explosive motions?

    Yes and no. Individual fibers are either On or Off, but individual fibers are grouped into bundles, and any one muscle is composed of many bundles. When you flex a muscle to move a thing, your brain only recruits some of the bundles. The exact amount is determined by some combination of your willpower, focus, training level, and adrenaline. As you train (that is, try really hard to lift something heavy), you teach your brain that you're going to be lifting heavy things a lot going forward, which makes your brain recruit more muscle fibers when you actually go ahead and lift the thing. So you're right in one sense, and incomplete in another.

      That can't be everything though because otherwise your body wouldn't physically change when you train and they clearly do. Also why wouldn't evolution just make us all strong all the time if it only requires neurological changes?

        It’s not everything. See muscle hypertrophy: https://en.m.wikipedia.org/wiki/Muscle_hypertrophy https://en.m.wikipedia.org/wiki/Muscle_hypertrophy

        Probably a combination of not needing to be very strong (we don't use raw strength to hunt very often) and a metabolic cost.

They don't mean it like we know it, they mean that you can rebuild muscle quickly, basically.

Muscle memory is used to describe both, actually. Linked on that page is this in a small section about strength and adaptation: https://en.wikipedia.org/wiki/Muscle_memory_(strength_training) https://en.wikipedia.org/wiki/Muscle_memory_(strength_traini...

That’s always the way I’ve heard the term muscle memory used in a technical setting, but the people I’ve met who go to the gym a lot use it to refer to the phenomenon of gaining back lost muscle much more quickly than it took to build it in the first place.

i think they are using the more general definition of memory according to which e.g. antibodies are a memory
