Why aerobic exercise can enhance memory? Seek an answer
In daily life, we find that most people who love life and sports are full of energy and have strong learning ability and memory. This is because aerobic exercise can enhance memory. So, why can aerobic exercise enhance memory? 1. Exercise accelerates glucose metabolism and improves cerebral blood circulation. Exercise accelerates glucose metabolism, reduces psychological stress that will damage memory, and thus slows down memory decline. In addition, aerobic exercise can improve cerebral blood circulation, help memory and increase intelligence. 2. Exercise can improve cardiopulmonary function and increase the content of hemoglobin in blood. Brain tissue is most sensitive to oxygen, and brain fatigue is often related to hypoxia. A person's memory depends on the brain. Brain tissue is the most sensitive to oxygen, which consumes a quarter of human oxygen demand. If there is insufficient oxygen supply to the brain, there will be brain fatigue, which will reduce people's memory. Therefore, the level of memory has a certain relationship with human respiratory system, circulatory system and hemoglobin content in blood. Long-term reasonable physical exercise will significantly improve people's cardiopulmonary function and circulatory system, especially long-term reasonable physical exercise will increase the content of hemoglobin in blood. Experiments show that the hemoglobin of people who exercise regularly is higher than that of people who don't exercise regularly1.35g. 3. Exercise can stimulate the growth of brain cells, thus enhancing memory. Researchers believe that regular exercise can promote cell growth in memory-related areas of the brain. Researchers at the University of Cambridge in the United Kingdom conducted experiments with mice to study the relationship between exercise and brain function. They divided the experimental mice into two groups. One group had a treadmill in its cage, and the other group didn't. After calculation, the similar memory of "running group" mice is significantly higher than that of "non-running group". By analyzing their brain tissues, the researchers found that the gray matter in the dentate gyrus of hippocampus in the "running group" mice increased during the experiment. The specific reason is not clear, and the analysis may be related to some hormones produced when exercise accelerates blood circulation and exercise. However, the "non-running group" mice did not have the above brain tissue changes. 4. Exercise can improve the level of chemicals related to cognitive functions such as memory and attention in the brain. Sticking to regular aerobic exercise can improve the level of chemical substances related to cognitive functions such as memory and attention in the brain, thus improving cognitive ability, allowing you to cope with work and study calmly, and often having inspiration for improving innovation ability. 5. Exercise can promote the secretion of nerve growth factor in brain tissue and prevent the deterioration of brain function. There are about 654.38+000 billion neurons in the human brain, which will continue to produce and change in adulthood. Although some of them will decline with the increase of age, if we persist in exercise, we can promote the secretion of nerve growth factor in brain tissue and prevent the deterioration of brain function. 6. Exercise can increase maximal oxygen uptake and improve cerebral oxygenation. Researchers at the University of Montreal, Canada, observed the brain activities of volunteers during exercise and participation in the test with the help of near infrared spectroscopy, and found that their maximal oxygen uptake, brain oxygenation and brain cognitive function were significantly improved. Researchers believe that exercise can improve the health of arteries and blood vessels, so that the brain can make better use of oxygen, thus enhancing brain power. Friendly reminder of Zhenjiang Elderly Health Network: Regular aerobic exercise includes brisk walking, jogging, swimming, yoga, Tai Ji Chuan, aerobics and cycling. They can not only strengthen the brain and improve memory, but also make people feel happy, improve sleep and strengthen their physique.
