What do firm legs, old age, and brain have in common?
The stronger your legs are, the longer your brain will age. This is indicated by a ten-year study of King’s College London in 300 twins.
According to the team of researchers, leg strength is a useful indicator of how much exercise the person does to keep the mind in good shape.
This is because – according to the article published in the journal Gerontology – exercise releases in the body chemical substances that help stimulate the brains of the elderly.
To this end, 150 pairs of twin sisters of the age range from the age of 43 to 73 years were enrolled.
The strength of the legs was measured using a modified gym machine, which recorded both velocity and power of extension of the limb.
At the same time, brain capacity-both at the beginning and at the end of the study was measured by computerized tasks that tested memory and mental ability to

In general, twins who had strength in their legs at the start of the study, a decade later maintained their cognitive ability and reported fewer changes in the brain associated with age.
“When it comes to cognitive aging, leg strength was the factor that had the greatest impact in our study,” said Dr. Claire Steves, chief of research.
“Other factors such as heart health were also important, but the link with leg strength remained even after we took these factors into account.”
Dr. Steves believes that leg strength “is an indication of the type of physical activity that is good for the brain.”

Experts believe that more studies are now needed to determine exactly how much the physical shape of the legs is a determining factor in
brain health, regardless of the individual’s lifestyle.
The director of the Alzheimer’s Society in the UK, Dr. Doug Brown, said that this research adds to the growing evidence that physical activity could help
care for both the body and the brain.
“However, we still do not fully understand how this relationship works and how we can maximize its benefit.”
“And we still have to see if the recommendations in memory tests translate into a decreased risk of dementia.”
Alzheimer Research UK’s research director Simon Ridley said that generally staying active help reduce the risk of dementia, and now “it’s important to
take into account both strength training and aerobic exercise
