Den neurologiske sundhed forbedres, når disse muskelgrupper bevæger sig mere.

Brugen af benmuskler hjælper med at danne nye sunde hjerneceller, viser ny forskning.

Benene får ikke blot beskeder fra hjernen om, hvornår de skal flytte sig.

Benbevægelser, specielt dem der bærer vægt, sender også vitale beskeder tilbage til hjernen.

Kommentar: Delvist oversat af fra Working your leg muscles helps to grow healthy new brain cells

The new brain cells created by movements of large muscle-groups in our legs help us deal with new challenges and adapt to stress.

The study provides an insight into why patients with diseases that limit their mobility can rapidly decline.

Dr Raffaella Adami, the study's first author, said:
"Our study supports the notion that people who are unable to do load-bearing exercises - such as patients who are bed-ridden, or even astronauts on extended travel - not only lose muscle mass, but their body chemistry is altered at the cellular level and even their nervous system is adversely impacted."
The conclusions come from a study in which mice's hind legs were restricted in movement for 28 days.

This restricted the growth of new brain cells by 70%.

Dr Adami said:
"It is no accident that we are meant to be active: to walk, run, crouch to sit, and use our leg muscles to lift things.

Neurological health is not a one-way street with the brain telling the muscles 'lift,' 'walk,' and so on."
The study was published in the journal Frontiers in Neuroscience (Adami et al., 2018).
