A new study conducted at the Boston University School of Medicine found that exercise during middle age can lead to better brain health later in life. This study spanned 20 years and found that fewer fit participants at age 40 had a greater amount of brain shrinkage 20 years later when compared to participants who were in better shape.
This study looked at the data for about 1,100 participants who went through MRI and treadmill testing when they were 40 years old and then again when they were 60 years old. Results showed that people with higher blood pressure and a greater heart rate increase during exercise at 40 years old also had more significant brain shrinkage 20 years later.
These findings were published in Neurology on February 10, 2016.
