Exercising is very essential for keeping a good health and staying fit. Now, researchers have given us more reason to put the running shoes on. A recent research suggests that poop physical fitness could cause smaller brain later in life.

Author of the research, Ph.D., with Boston University School of Medicine, Nicole Spartano said, “Brain volume is one marker of brain aging. Our brains shrink as we age, and this atrophy is related to cognitive decline and increased risk for dementia. So, this study suggests that people with poor fitness have accelerated brain aging,” CBS News reported.

In order to reach the findings, the researchers observed around 1,583 participants who were enrolled in the Framingham Heart Study. During the study, the participants took the treadmill test at the average of 40 and then another test almost after two decades along with MRI brain scans. None of the participants had any heart disease or dementia at the beginning of the study.

Along with brain health, the researchers also evaluated blood pressure and heart rate during the tests. After the long-term study, the researchers excluded participants who later developed heart conditions or started taking beta blockers. The researchers hence found that there was a significant association between changes in brain volume of the participants and exercise.

The researchers said that the data accumulated showed that people who had poor physical health at the beginning of the study and did not get much exercise later were seen with smaller prawn size.

Commenting on the findings of the study, Spartano further said, “he difference with our study was our observation that fitness earlier in life was related to brain aging two decades later. Over the course of a lifetime, these mechanisms may have an impact on brain aging and prevent cognitive decline in older age.”

The findings of the research were published in the online journal Neurology, the medical journal of the American Academy of Neurology.
