What does muscle memory mean?

The significance of muscle memory has two levels: motor memory is actually stored in cerebellum instead of muscle; Muscle can adapt faster in the second round of training, actually because of the muscle nucleus left by the first round of training.

1, the cerebellum will store motor memory: when exposed to a new action, the cerebellum will form a memory about the action, and the more times this action is repeated, the stronger the memory.

2. The number of muscle nuclei in skeletal muscle will increase: after a period of training, muscle fibers will become bigger and stronger, and the way to achieve this effect is to increase the number of muscle nuclei. Previously, everyone's cognition was that after stopping fitness training, the number of muscle nuclei would decrease with cell apoptosis and eventually return to normal level.

However, recent studies have found that most muscle nuclei do not decrease with apoptosis after stopping training. This makes it possible to get muscle growth faster after resuming training, because the body does not have to regenerate muscle nuclei.

Extended data:

Collaborative memory method: all parts of the human body have memories. When you are very skilled, you can continue to do it without going through your brain. The two parts of the human body can also communicate directly without going through the brain, which is coordination.

Collaborative memory is a combination of vision, hearing and action, and it is also used to remember some contents.

Memorization by eyes alone is the memory of visual symbols by the brain, which is called "visual symbol memory". The memory of reading, writing and sports includes the memory of muscle movement specialized in sports in cerebellum, which is called "sports memory". "

Visual symbol memory is forgotten quickly, while "sports memory" is forgotten slowly, even for life. Even if a swimmer has not been in the water for decades, it is difficult for him to drown himself.

The actions remembered by cerebellum are not limited to the movements of trunk and limbs, but also include the subtle movements of muscles in various parts of the body. For example, a series of accurate, lasting and rapid movements of violinists can be reproduced without thinking, and almost become habitual movements. The skillful and accurate movements of calligraphers, painters and sculptors are all related to sports memory.
