Is leg strength related to brain health? A British study published in the American Journal of Gerontology found that strong legs help delay the aging process of the brain.
A research team from the Department of Twin Research and Genetic Epidemiology, King’s College London, UK, conducted a 10-year health follow-up study on 162 pairs of female twins. At the beginning of the study, the researchers used exercise equipment similar to stationary bicycles to measure the power of the muscles of these 43-73 year-old women participating in the test. They also measured the height, weight, grip strength, vital capacity, blood pressure, blood sugar and blood lipids of the participants. Health data. Participants also underwent multiple memory tests, answered questionnaires about daily physical activity levels, current health conditions and lifestyle factors, and received brain magnetic resonance imaging (MRI) scans. Ten years later, the women participating in the test again received memory tests, brain MRI scans, and brain cognitive decline tests. To find out whether leg strength can predict differences in brain structure and function, the researchers conducted a 12-year follow-up survey of 20 pairs of identical twins.
After excluding age, lifestyle and psychological factors, the researchers found that the stronger the muscles in the legs of the women tested, the slower the aging process of brain function and structure after 10 years. Researchers also found that the more women who do not exercise, the faster their brain declines. Women with more active brains are more active in physical exercise and love to participate in physical exercises.
The researchers said that the new research results show that there is a positive correlation between leg muscle strength and brain cognitive health. Physical activity and leg muscle strength have obvious protective effects on cognition related to aging.
Why do snowflakes make people happy
After a heavy snowfall, the entire city was wrapped in silver, and people felt sincerely happy. Why is everyone happy when they see snowflakes? Recently, a new study published by the University of Oregon in the Journal of Humanities and Social Sciences Communication has discovered the mystery.
The research team first discovered that when a large number of small objects are repeated, such as tree branches and the spiral shape of shells, the brain will enter a relaxed state and make people feel comfortable. To this end, the research team included 82 18-33-year-old adults and 96 3–10 year-old children, and asked all participants to observe the patterns on the tablet computer several times. Participants were randomly assigned to observe the spectrum like branches, snowflakes or clouds in each round. After 10 rounds of observation, the researchers conducted questionnaires and data collection and analysis. It turns out that both adults and children are more fond of complex “fractal” patterns.
The term “fractal” was born in 1975, but before many artists have applied these natural patterns to their creations and produced wonderful effects. Professor Robles, who is in charge of the research, said: “We found that people prefer the most common natural patterns, that is, statistical fractal patterns of low to medium complexity. This preference is not derived from decades of contact with nature, nor is it There are individual differences in the way we process images. This is likely to be something that humans are born with, because the brains of 3-year-old children have responded to fractal patterns.”
Researchers say that this human feeling is a gift from nature to us. But now every corner of the city is too “rules and rigid”, man-made buildings make us visually fatigued. Therefore, trying to incorporate more fractal elements into urban construction is beneficial to the development of children and the mood of the people.
