A study published in the American Journal of Neurology (Neurology) suggests that young people who run or participate in other aerobic activities can maintain memory and thinking ability in the middle age (43 to 55 years).

A team led by researchers at the University of Minnesota in the United States conducted a long-term study of 2747 healthy people with an average age of 25 years. During the first year of the study, the subjects were tested on a treadmill, which increased the speed of the treadmill until they could not continue. Test again 20 years later. Cognitive tests were performed in the 25 years after the start of the study to measure verbal memory, psychomotor speed (the relationship between thinking and physical activity) and executive function.

In the first test, subjects were able to exercise on a treadmill for 10 minutes. Twenty years later, the number fell by an average of 2.9 minutes. In the first test every 1 minutes of exercise, after more than 25 years after the memory test can recall more than 0.12 words, psychomotor speed test results are better. After 20 years, people with lower levels of treadmill tests were more likely to get better grades in executive function tests than those with lower levels.

Co author David Jacobs said: "although these changes may be small, but significant, more than the age of one year old greater impact. Other studies in older adults have shown that these tests are one of the strongest predictors of dementia in the future." "This important study is a reminder that young people should be involved in aerobic fitness activities such as running, swimming, cycling or aerobic classes," he said."
