It goes deeper than that, but I think you know that. Muscle memory (all in the brain) is all subconscious and is a very hard thing to forget. Just stroking a cue or swinging a golf club involves dozens of muscles in your body, each one needing a signal from your brain to "fire" (both when to fire and how much). Through repetition, that sequence and its timing become subconscious, resulting in what we call "coordination". All the brain knows is to send signals to specific neurons at the right time. The more precise the brain gets at doing that, the more coordinated we become. If something happens to just one of the neurons involved in that sequence (killed by alcohol or by age or by a stroke, etc.), the brain doesn't know that. So it keeps trying to fire that neuron and others (there are multiple neural pathways to each muscle in the body, each taking a different amount of time to arrive at the right muscle, like roads on a map) until it gets some kind of signal that the muscle fired, but by the time it has the timing and coordination of the entire sequence is off. It takes the brain a long time to realize that neuron is dead and to start with another, and even more time to coordinate the different sequencing that has to occur, because in the time it takes to "forget" that one neuron different muscle memory develops, which may or may not be right and may or may not have unintended side effects. Maybe someday there will be a way besides repetition to "rewire" the subconscious brain - that's something to hope for.Yes, there is. Of course your muscles don't literally have memory. It's just a term. Muscle memory refers to the body's ability to retain and recall motor skills through repetition and practice, allowing you to perform actions without conscious thought.
Is there somebody out there that thought muscles actually have memories? Maybe...? Is there somebody out there that didn't think your brain is involved in physical activity? I...hope not.
That's what I don't get about these psych coach guys. It seems like they just ladle up the simplest most obvious statements as deep thoughts, like, "We are all human and make mistakes". If it helps somebody, great, I just honestly don't get it. "Your mind is involved in physical action." Yeah, obviously.
That's probably more than anyone here wants to know, but it's become fascinating to me since a series of minor strokes destroyed my pool stroke, my golf swing, and pretty much anything that required "coordination" overnight. Literally, it's like I physically aged 25 years overnight, but retained all of my cognitive abilities. It's tough to overcome, both physically and mentally.
I don't think it's unreasonable to get help understanding the relationship between conscious and subconscious thinking. Maybe Nicklaus would have won 30 majors with the help of a psychological coach. Like the answer to the age-old question "How many licks does it take to get to the tootsie roll center of a Tootsie Pop?", the world may never know.
