`` It turns out that people who are slow to walk are quick to age their brain and body ''

Past research has revealed that `` the risk of death due to heart disease changes depending on walking speed '', but the latest survey targeting about 900 people said that `` walking speed is related to the aging speed of the brain and body Is found. '

New Zealand Study Connects Walking Speed with Brain Health in 45-Year-Olds | Duke Today

The research group of Line Jee Hartmann Rasmussen and others at Duke University clarified the relationship between walking speed and aging. Rasmussen et al. Found that the walking speed of elderly people in their 70s and 80s is closely related to the functions of the body and the central nervous system, which was found in past studies. We decided to verify the hypothesis that the same trend may be seen even in the middle-aged period.

Specifically, among the subjects of the Dunedin Study who tracked 1037 people born in Dunedin, New Zealand from April 1, 1972 to March 31, 1973, they survived to 45 years of age. In addition, 904 people who agreed to cooperate in the survey conducted tests such as walking speed measurements, MRI brain scans, and health examinations.
As a result, it turned out that the slower the walking speed at the age of 45, the smaller the volume and surface area of the brain, the more aging the brain. In addition, 19 types of medical examinations such as blood pressure and dental health showed signs that physical aging was early. Furthermore, an experiment in which eight volunteers showed the subjects' facial photographs also showed that people who were slow walking looked old, and the relationship between walking speed and aging was from the appearance to the whole body including the brain. It has been found that
In addition, when comparing the walking speed with the results of the cognitive function performed when the participant was 3 years old, it was found that the subject with low cognitive function when 3 years old had a slow walking speed at the age of 45 It is that.
The research team speculates that there are six possibilities for factors related to cognitive function in early childhood and walking speed at age 45:
・ A common brain area may be involved in high cognitive function and walking function.
・ If the cognitive function is high, there is a possibility that smoking cessation, healthy lifestyle habits, healthy eating, etc. are kept in mind.
・ If cognitive function is high, better health information can be accessed and health management may be easier.
• Higher cognitive function provides higher education, which may have reduced the risk of placing yourself in an unsafe work environment or in situations that are harmful to your body.
・ Because the brain is a delicate organ among organs, there is a possibility that the effect of a decline in organ function may have been noticeable.
• Genetic factors may affect both cognitive and gait functions.
Rasmussen pointed out, “We found that the gait test can be used not only to measure the motor function of the elderly, but also as an integrated measure of lifelong life,” and the relationship between walking speed and brain and physical health. Emphasized the significance of the research that was revealed.
