Conditions body stay in shape in the 40s was not only keep us from heart disease, but also protects our brain from shrinking at a later date.
Researchers from Boston University School of Medicine found no relationship between the volume of brain tissue at the age of 60 with one's level of physical fitness in the 40s.
People who are in their 40s have a lower fitness level or have a rise in diastolic blood pressure (the bottom number in a blood pressure reading) and high heart rate after spending a few minutes on a treadmill in a low speed, volume tends to have smaller brain tissue at the age of 60.
"Someone with a lower fitness levels tend to experience an increase in blood pressure compared with the higher fitness levels," said researcher Nicole L. Spartano, PhD.
People with a higher level of fitness have better oxygen delivery to the brain. Physical exercise is also associated with blood vessel health and has an important role for brain health.
The study involved 1,271 people who were part of the Framingham Offspring Study to undergo treadmill testing at the age of about 41 years. Then, when the average age of those 60 years, they did an MRI brain scan and underwent cognitive testing.
This is not the first study to determine the correlation between physical fitness in middle age with brain health in later life.
A study published last year in the journal Neurology showed that physical fitness in adulthood was associated with better performance on tests of cognitive (thinking skills) in the early to mid 40s.
Another study, also published last year, showing the relationship between physical activity will actively reduce the risk of dementia in old age. (Monica Erisanti)
