Justin Roth, an American neuroscientist, found in the study that the brain responses of rats with exercise addiction are slower than those of normal rats. The report was published in the journal Neuroscience and Behavioral Neuroscience. As a result, Rodd said: "Although the exercise is good for the brain, it should also be adequate."
With moderate exercise, people will be smarter
On the human brain's side, there is a hippocampus-like raised part called the hippocampus, which is the organization in the brain that is responsible for learning and memory.
Researchers at the Thor Center for Biological Research in La Jolla, California, USA, have found through animal experiments that mice that like to walk on a roller have new cells on their hippocampus and are closed in common cages. The mice did not grow new cells.
Therefore, researchers believe that if people can regularly carry out regular, moderate amounts of exercise, they can also make the hippocampus in the brain grow more cells, making people's thinking, feelings, and reactions more sensitive. Become smarter.
Excessive exercise will make your brain stupid
High-intensity exercise can cause brain damage through a variety of ways. The depletion of energy substance ATP during exercise may be the main reason for the decline of central nervous function; redistribution of body blood, accumulation of free radicals, and acceleration of blood flow cause damage to the vascular endothelium that reduces the supply of blood and oxygen to the brain during exercise. Accumulation of acidic products not only affects the energy supply of the brain, but also directly suppresses the activity of the nerves, causing the brain function to decline.
Studies have shown that short-term high-intensity exercise reduces cerebral cortical activity, and long-term high-intensity exercise decreases extensive brain tissue excitability.
People in life often feel that after strenuous exercise, not only the body's response is slow, but also the brain has a short-term phenomenon of "can not keep up." This is not only related to the above factors, but also the result of the "protective inhibition" mechanism of the body itself.
When exercising excessively, the human body consumes a large amount of energy. In order to prevent the further consumption of energy, the function is suppressed. At this time, people will feel extreme fatigue, become weak, and the brain response will slow down. If excessive exercise is performed for a long period of time, the body's "protective inhibition" function is reduced in sensitivity, and the brain function is impaired. The manifestations of the symptoms include: inability to concentrate, insomnia, forgetfulness, etc., and in the long run, the health of the human body will be caused. Great harm.
Grasping scientific exercise
Whether the exercise is appropriate or not depends on the heart rate. It should be 60% to 85% of the maximum heart rate. It is worth noting that because each person's actual situation is very different, compared with the quiet heart rate, it should be a difference of 15% to 30%, or even more, so the choice of the optimal amount of exercise should be based on their own age, gender, occupational characteristics, physical status , health level, sports foundation, living environment, purpose and mission, etc.
It is also possible to look at the relative response of the human body after exercise by checking the suitability of exercise. For example, you can refer to people's sweat flow and ease of exercise. You can also pay attention to your appetite, sleep, and whether you have the desire to participate in sports the next day.
Relatively speaking, the elderly can perform a single exercise of the hand under the premise of aerobic exercise, and enhance the coordination ability of the human body. Children must do more mechanical exercises, such as placing blocks, etc., seemingly simple, in fact, can greatly promote the child's brain development and hand-eye coordination.
The key is to grasp the exercise intensity. In addition to keeping the heart rate in a proper range, there must be a strong concept of time. Generally speaking, each exercise time in the aerobic state is appropriate in 30 to 60 minutes. Once it is overdone, it is not only useless, but may be Damage to bodily functions.
