? As early as the18th century, the French thinker Voltaire put forward a famous conclusion: the concept of sports philosophy and the concept of life. He said that "life lies in movement", and the movement of life is an advanced form of material movement. Protein is the main material basis of life movement, and life movement is the inherent attribute and important way of existence of protein. Life is limited, but it will get old with the passage of time, and the significance of exercise is that we not only exercise in space, but also exercise in time. Voltaire, 80, climbed the mountain with his friends to watch the sunrise. As a result of exercise, he keeps healthy and energetic. He is getting old, but he is younger than anyone else.

Exercise is essential for us, and health is the ultimate goal of our exercise. Humans have never stopped exploring the effects of exercise on health. John Ratey, a clinical associate professor at Harvard Medical School, published the book "Exercise Transforming the Brain", which caused a sensation in the scientific community, revealed the relationship between the brain and exercise, and brought human research into a new milestone. Dr. Reddy tells us with a large number of powerful research results and cases that exercise can not only strengthen the body and exercise muscles, but also exercise the brain, transform the mind and IQ, so that the brain can exert its maximum potential. Exercise can stimulate the brain stem, provide energy, enthusiasm and motivation, regulate neurotransmitters in the brain, change people's established self-concept, stabilize emotions, eliminate negative emotions such as anxiety, depression and depression, improve learning ability and memory, and prevent or even reverse some decline caused by brain aging.

In the book "Exercise Transforms the Brain", the "Zero physical education class" experimental project in Naperville Middle School verified the relationship between exercise and learning. Physical education class, also known as "physical education class for study preparation", is a new type of physical education class that improves students' consciousness through exercise and prepares for a day's study. Research shows that exercise improves students' attention and memory, at the same time, students' dopamine increases after exercise, and students' interest in learning remains at a high level. The final learning effect can be seen. Zero physical education class not only makes Naperville students the healthiest students, but also makes them the smartest students.

? With the development of today's society, people's living standards and quality are constantly improving, and the ways of exercise are becoming more and more abundant and diversified. The most cost-effective thing is probably running. Regardless of the venue and time constraints, put on your sneakers and you can start. In recent years, more and more neuroscientists have begun to study the effects of running on the brain. They conducted indoor and outdoor runners, marathon runners and some animal experiments, which confirmed that running can affect our cerebral cortex. In the research report published in Cerebral Cortex in 2008, running is related to the changes of brain chemical transmitters. When we exercise, we secrete a substance called endorphin, which can make people cheer up and feel happy, while reducing negative emotions such as depression and anxiety, so it is called "happy hormone" and "young hormone". The secretion of endorphins requires exercise to reach a certain intensity and a certain time. It is generally believed that moderate-intensity exercise, such as running, can stimulate the secretion of endorphins for more than 30 minutes.

Long-term running makes the brain more agile, better memory and more focused. Finnish scientists spent three years comparing the exercise data of 10 male twins, so that one of them ran at least twice a week and the other did not exercise, and then scanned their brains respectively, and found that the gray matter area of the brain was more developed in those who ran every week. Gray matter is the center of information processing and can respond to various external stimuli. Obviously, running can improve brain vitality, reduce the atrophy of gray matter area, and make people's thinking more agile and younger; The University of Maryland scanned the brains of athletes who didn't run for 10 days. Before and after the data showed that their hippocampal blood flow decreased. Hippocampus is the memory system of human body, which is closely related to learning and memory. The decrease of blood supply to hippocampus means the decrease of blood supply to the whole brain, which leads to the decline of learning and memory ability, so maintaining long-term running will improve memory and learning ability; Research by the University of Canberra in Australia has proved that high-level endurance athletes have stronger concentration and anti-mental fatigue ability. They used two groups of bicycle volunteers to do a comparative experiment. One group was a professional athlete *** 1 1, and the other group was an amateur athlete ***9, who completed a 20-minute test race respectively, and then conducted a direct test and a 30-minute cognitive task before the test. Cognitive task, as its name implies, is a task that requires the brain to concentrate. If it is carried out for a long time, it will cause mental fatigue and inhibit brain activity. The purpose of the task is to compare the effects of exercise ability on brain concentration and fatigue. Professional players' test scores are obviously better than those of amateurs. After long-term training, players' brains will be more focused and more anti-fatigue.

? To sum up, persisting in running for a long time can really make our brains smarter! Running can not only strengthen the body, but also strengthen the brain. But running exercise should be arranged reasonably. If you keep exercising for a long time, your brain will get better and better. It is not that the greater the intensity of exercise, the better, nor that the longer the exercise, the better. Your brain will be overloaded and damaged. German scientists once studied an experiment. They scanned the runners' brains before, during and after a ridiculous 64-day, 4,800-kilometer ultramarathon race. The final data is that the gray matter volume of these runners is reduced by 6% compared with that before running, while the brain atrophy of ordinary elderly people is only 0.2% every year. Excessive exercise will undoubtedly aggravate the speed of brain atrophy, and the brains of contestants may return to normal after 8 months, but the consequences of long-term excessive exercise can be imagined. Only moderate scientific exercise can bring us practical benefits.
