I just got told:


Apparently 運動神経 means motor nerve: enter image description here

What does 運動神経が良い mean in this context? The conversation was about swimming, not something where reflexes are that important I believe.

  • Swimming as in competitive swimming? In which case reflexes would certainly be important I think...

In this context it does not have much to do with reflexes or nerves.

It just means "good at sports".



A motor nerve is a nerve that carries command information out of the central nervous system (CNS) and toward effectors (muscles or glands) that will execute the commands.

Even if we take this definition literally, I think the expression ”運動神経が良い” is not too off. If we take motor nerve is good as transmitting information efficiently from CNS to muscles efficiently, I think it applies to real movement in sports.


運動神経 = motor nerves, reflexes

運動神経がいい = motor nerves, reflexes are good

Speaking of physical abilities, if your motor abilities or reflexes are good, chances are that you're the athletic type. It does take a good amount of reflex and reaction whenever playing a sport, especially for competition's sake.


I believe it's also a common way to express "gifted at sport(nerve)". Since it's mainly talking about physical capacity as talent.
