If you start working out, will your brain become younger?

Sample: 309 subjects aged 62-70 years.

Participants were divided into three groups - intensive training (heavy weightlifting three times per week), moderate training (several sessions during the week, including at home on their own), and a group without physical exercise. All groups engaged in exercises for one year and underwent brain scanning.

Shown: intensive training - improvement in connections in the prefrontal regions. In the intensive and moderate groups, a significant reduction in the biological age of the brain after one year of training - the effect persists even after two years. A correlation was found between an increase in leg strength (a standard measure of physical fitness) and a reduction in brain age, but the effect is moderate and only in the moderate training group, not the intensive one.

Like if you're already taking your beloved grandma to bench press a hundred kilos.
