It's Motor Memory not Muscle Memory

I am aware that the phrase "muscle memory" might be deceptive because it implies that our muscles can remember movements independently of the brain and nervous system, which is not substantiated by scientific research. Instead, what is more correctly referred to as "motor memory" is the capacity to learn and execute movements more effectively over time thanks to changes in the brain and nervous system.

The term "motor memory" describes the brain's capacity to memorize and imitate a movement pattern, frequently through repetition and practice. As the neural connections between various brain regions and the muscles used in movement get stronger and more effective, it entails changes in the brain and nervous system.

Contrarily, the ability to perform a movement without paying attention to it is referred to as having "muscle memory," which indicates that the muscles themselves have the memory for the movement. This is not totally true, though. The motor cortex and other areas of the brain involved in motor control are where the memory for a movement is really kept. The muscles do not "remember" how to carry out a movement on their own.

Thus, despite their similarities and frequent use as synonyms, "motor memory" and "muscle memory" pertain to slightly different ideas. Since it represents the alterations in the brain and nervous system that underpin the capacity to learn and execute a movement, motor memory is the more scientifically correct term.

I hope this helps you on your journey
