Obviously walking a lot is effective for prevention of aging in the brain

It has long been said that moderate exercise is useful for prevention of aging in the brain, but those who actually walk well by long-term surveygray matterThere are many,dementiaYaAlzheimer's diseaseIt is supported that the risk of developing the disease is low, specifically how much momentum is effective in preventing brain agingThresholdWas revealed.

Details are as below.Walking May Ward Off Brain Shrinkage, Study Says | Health | Epoch Times

University of PittsburghDr. Kirk Erickson of Associate Professor Psychology Department and others studied the relationship between physical activity and gray matter volume and cognitive dysfunction in a 13 - year study of 299 subjects. Thesis isNeurologyIt will be published in the magazine.

299 subjects were reported to be healthy adults (average age 78 years) without cognitive dysfunction at the start of the study, the amount of physical activity was reported in the form of "How many blocks do you walk a week?", With high resolution brain scangray matter, And received a medical diagnosis of cognitive impairment four years later (13 years after the start of the survey). The walking distance of subjects in one week ranged from 0 block to 300 blocks (average 56.3 blocks,standard deviation69.7) that it was.

As a result, it became clear that the amount of gray matter after 9 years differed depending on walking distance. Specifically, a group walking more than 72 blocks (about 6 miles to 9 miles: about 9.7 km to 14.5 km) per week will have a frontal area, occipital area, inner olfactory area, hippocampal area It was said that the amount of gray matter was large. However, the gray matter quality does not increase as the walking distance is longer, and there seems to be no significant difference in 72 blocks or 300 blocks. It seems that the proportion of cognitive dysfunction occurring 13 years later was also 1/2 compared to the group not walking in well walking groups.

"The brain shrinks in late adulthood and this leads to problems arising in memory. Our research results suggest that designing an appropriate exercise plan for the elderly as a promising approach to preventing Alzheimer and dementia We will push it in. If the regular exercise of middle age leads to maintaining the brain's health, thinking ability, memory ability in later life, encourage people of all ages to do regular exercise Will be an increasingly important public health challenge, "said Erickson Associate Professor.

If you say 6 to 9 miles a week, it seems to be about 1.4 km ~ 2 km a day, people who are achieving it by daily commuter school etc are many distances. People who are close from the house to the station or from the station to the company are not far from being able to walk unreasonably without going around for a while, taking a detour in the way home or trying to get off at one station.
