Even light exercise, such as walking, increases the speed of cognitive processing in the brain. [사진=클립아트코리아]It is well known that exercise is good for brain health. What kind of exercise should I do? Although the general consensus is that moderate to vigorous exercise has cognitive benefits, all types of physical activity, including light walking, have been shown to increase cognitive processing speed.
According to ‘Medical News Today’, researchers at Pennsylvania State University School of Medicine monitored the activity levels of experiment participants in real time through their mobile phones and examined their cognitive processing speed several times a day.
Researchers found that engaging in daily activity, regardless of exercise intensity, can lower cognitive age by as much as four years in a short period of time.
Participants were surveyed five times a day about their physical activity on a mobile phone app for seven days and participated in two brain games.
The first game involved pressing symbols at the bottom of the screen that matched the symbols displayed at the top. After 12 rounds, the average response time was recorded in the app. This score increased after physical activity.
The second game involved remembering and marking the positions of three dots on a grid. Scores did not improve after physical activity in a four-round game, but participants responded faster, even if incorrectly.
“As we age, our cognitive processing speed can slow down by up to 15 milliseconds (ms) per year,” said Jonathan G. Hakoon, Ph.D., assistant professor of neurology and psychology at the university. People who participated in this study gained about 60 milliseconds faster. This corresponds to a cognitive processing speed that slows down by about 4 years.
The study included light activities (such as housework, walking the dog, cleaning, and other activities requiring minimal effort), moderate activities (such as brisk walking, gentle biking, jogging), and vigorous activities (such as running, brisk biking, and difficult hiking). ) classified the participants’ physical activity.
“It’s interesting that even short-term routine activity can have benefits,” said Dr. Vernon Williams, a sports neurologist. “High-intensity exercise and long-term exercise releases certain chemicals and neurotransmitters in the brain that are good for cognitive health and also has an effect on improving cardiovascular function,” he said. “Increased blood flow to the frontal lobe is also related to or correlated with regular physical activity.” “There may be a relationship,” he said.
