Talk:Muscle memory (strength training)

Does this apply to skeletal muscle only or to cardiac muscle as well? 70.230.157.75 (talk) 06:26, 11 March 2012 (UTC)

There need to be a clear distinction between CNS muscle memory (cerebellar), known and studied for many years, and the newly researched muscle memory within the muscle cell itself which has been attributed to the multiple nuclei they contain. The article is otherwise a good summary of the current situation so far as muscle cell memory is concerned. — Preceding unsigned comment added by 90.217.39.170 (talk) 10:05, 3 November 2013 (UTC)

No muscles do not contain memory, muscle memory is all in the brain:
 * https://nationalpti.org/what-is-muscle-memory/
 * "Obviously muscle memory is not memory actually stored within your muscles, but rather memories that are stored in your brain that act as a cache of frequently performed tasks by your muscles. Every time we teach our bodies how to do something- whether it’s surfing, yoga, running, etc. – our brain creates a physiological blueprint."
 * https://learnmuscles.com/blog/2017/08/18/what-is-muscle-memory/
 * "So, let’s explore the idea of muscle memory in this context. The first misconception is the belief that postural muscle memory resides in muscle tissue itself. The muscular system [...] does not hold the key to its own memory. Certainly, adhesions present within musculature can determine its ability to stretch, and therefore affect its degree of passive tension and therefore the posture of the body. But if we are referring to active muscle tone, in other words, muscle contraction, the memory for that resides elsewhere. This can be easily understood by considering a person who has suffered a traumatic injury that severs the lower motor neurons (LMNs) that synapse with and control a muscle. In these cases, the muscle will become flaccidly paralyzed and will have no ability to contract (unless electrical stimulation is applied from the outside). If the memory for the muscle contraction were actually within the muscle, then it would be able to contract, even if its nerve were not functioning."

 * "Yes and no. There is no literal memory in the muscles, but the thing people call “muscle memory” exists, though the name is a misnomer. A better name might be “subconscious memory,” as the information is stored in the brain, but is most readily accessible—or only accessible—by non-conscious means."
 * https://www.popsci.com/what-is-muscle-memory/
 * "It feels to us as if that memory is stored in our muscles—as if they’re remembering how to perform an action without our really being aware of it. But the reality is that the activity is happening in our brains [ https://www.pnas.org/content/112/11/3541/ ]."

 * "Muscle memory is a type of procedural memory. However, the name of this particular phenomenon is a bit of a misnomer. Although it includes the word ‘muscle’, the memory center actually lies in the brain, not in the muscles."

Yes muscles can contain memories or certain types of memories:
 * https://www.skinny2fit.com/muscle-memory/
 * "In Conclusion \\ As mentioned at the beginning of the article there is a debate as to whether muscle memory exists. \\ Whilst there have been some well-received studies that support the theory, there have been other studies that could not find any evidence of myonuclei surviving the non-training atrophy of muscle. \\ Yes, muscles do have memory. Not the kind of memory that we store within our brains. But a special kind of memory that is unique to the myocytes, or muscle fibres themselves. [...] What cannot be denied is that training after a long layoff can produce results a lot faster than training for the first time."

 * "Muscle memory refers to individuals with a history of previous training which can acquire force quickly on retraining. This is mostly attributed to motor learning in the central nervous system. However, a recent research study [ https://www.pnas.org/content/107/34/15111.full?sid=728e4764-0bd1-4cce-846b-282faf187bb1 ] showed that “memory” is stored as DNA-containing nuclei, which proliferate when a muscle is exercised. In addition, those nuclei aren’t lost when muscles atrophy."
 * https://articles.jebhealth.com/2017/12/15/science-behind-muscle-memory/
 * "Where is the muscle memory, or procedural memory, stored? – in the brain or in the muscles? The answer is both. Muscle memory is encoded through frequent repetitions. The more you engage in an activity, the more your brain and body familiarise itself with it. This familiarisation is stored in your long term memory in two main ways. The first is through the Cerebellum in the brain, and the second is within the muscle cells. [...] More nuclei growth is facilitated within the muscle when you first exercise and start to train. The nuclei you have in your muscle helps develop more tissue and build more muscle. It is, in short, these nuclei that are responsible for muscle synthesis. When you first start training, a certain amount of time is required to build, expand and duplicate these nuclei. \\ Once you stop training, the duplication of these nuclei ceases, and for a long time, it was thought that these nuclei simply died over time. However, newer research shows that even after years of not training, these nuclei still remained in the muscles. The result is an easier and shorter path to getting back in shape. The body remembers the shape it was in before, as those nuclei are still in the muscles and are simply re-activated, instead of the body having to produce and “grow” more nuclei from scratch. This is one of the reasons why it is easier and faster to get back in shape if you had been in shape before."

Maybe there is no contradiction and it is just different topics. —73.3.132.105 (talk) 06:21, 5 May 2021 (UTC)

Is this seprate article needed?
The article is not clear enough how it differentiate from Muscle memory. TudorTulok (talk) 10:19, 7 February 2022 (UTC)
