According to a new study by the University of California, Los Angeles, elderly people over the age of 60 walk 4000 steps a day to improve their attention and memory.
In the two-year study, the researchers recruited 29 older people over the age of 60 who were not satisfied with their memory. They used an accelerometer to track their physical activity over a 7-day period and recorded their average number of steps per day Participants were divided into groups of 4,000 walking steps per day and less than 4,000 walking steps followed by a series of neuropsychological tests and magnetic resonance imaging scans that found that more than 4,000 walkings of a group of hippocampal (Key areas of memory deep in the brain) and surrounding areas become thicker than those who walk less than 4000. Researchers say the thicker of these areas, the better the performance of attention, information processing and execution , The stronger the cognitive function.The new study was published in the Journal of Alzheimer's disease.
The first author of the study, Professor Purwah Sidas University of California, Los Angeles, said: "Brain thickness is a more effective measure than the brain volume and can track subtle changes in the human brain independently predicting cognitive ability. Research will be devoted to understanding the causes of changes in the thickness of human hippocampus
