The human brain will experience shrinkage with age. But, we can do something to slow the effect. For example, with regular exercise.
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.
