Intellectual activity is produced by the matter of the human brain. Of course, human beings are inseparable from society, and human thinking activities depend on social practice, including experience and knowledge.

But in the final analysis, brain activity is the function of matter. Engels once said that thinking is the product of the brain. Regular participation in group exercises can enhance people's physique. A sound spirit comes from a sound body, which can increase the weight of the brain and the thickness of the cerebral cortex, increase the dendrites of brain cells, and create good material conditions for intellectual development.

Physical exercise gives the brain nutrition and oxygen. The only machine in the human body that manages thinking and memory is the brain, which is the general manager of the human body. The work of the human brain must have sufficient nutrition and oxygen supply. Adequate oxygen and nutrient supply are directly related to human health and help to improve the thinking ability and memory of the brain.

2. The effect of physical exercise on improving the reaction speed of brain cells.

Human intelligence, especially memory, is closely related to the number and integrity of temporary connections established by various parts of the cerebral cortex.

People who often participate in sports have keen sense organs such as vision and hearing, faster response speed of brain nerve cells and stronger analysis and comprehensive ability of cerebral cortex. The function of the brain is to receive and select information, analyze and judge information, organize information, store information and transmit information.

Physiologically speaking, the left brain is engaged in rational theoretical and analytical thinking, the right brain is the stage of emotion and will, and thinking is characterized by activities that dominate intuition and comprehensive thinking.

The activity of the left brain is a necessary prerequisite for the activity of the right brain. On the basis of the activity of the left brain, it arouses the excitement of the activity of the right brain, so that the movement of the left and right brains can be used freely, which belongs to the comprehensive type of two brains. This type is conducive to cultivating creative intuitive imagination.

A large part of the human brain's potential (mainly the right brain) has not been utilized, and exercise is a favorable means to develop the right brain.

Intellectual education requirements in physical education teaching

(1) Strengthen the education of sports knowledge and theory, and improve students' sports cultural literacy.

From a macro point of view, sports is a part of the culture created by human beings, which represents people changing their cognitive theories and methods. The expansion and broadening of modern sports culture requires physical education to attach importance to sports knowledge and theoretical teaching.

Knowledge is the guide of sports and the premise of mastering sports technology. With scientific knowledge and theoretical guidance, physical exercise can have a scientific basis and the exercise effect can be improved. Strengthening the teaching of sports knowledge theory can also give full play to physical education class's educational function and promote the all-round development of students' morality, intelligence, physique and aesthetics.

Sports in modern society has become an important part of people's lifestyle. People engage in sports not only for the needs of disease prevention and fitness, but also for the needs of personality development, emotional adjustment, social interaction, entertainment and rich life. Therefore, it is necessary for students to understand sports, appreciate competitive sports, organize small competitions, learn more about sports health care and improve their cultural quality.

(2) strengthen the movement of the weak side of the body and develop the potential of the cerebral hemisphere.

Higher neural activities, such as human intelligence, are realized through the brain. The two hemispheres of the brain control the movement and sensation of the contralateral limb respectively, and the signals of limb movement and sensation are continuously transmitted to the contralateral brain, providing information and conditions for the development of the brain. In other words, the development of the cerebral hemisphere is closely related to the movement of the contralateral limb, and the movement of the contralateral limb activates the function of brain cells.

(3) Pay attention to cultivating students' ability to analyze, solve and study by themselves.

Self-study ability refers to the ability to learn independently and effectively without the help of others; Students' self-exercise ability means that students consciously participate in physical exercise and can exercise by scientific methods. That is, to combine initiative with science in exercise, we must eliminate the blindness and ignorance of students' physical education learning.

The formation of self-exercise ability must maintain persistent indirect interest in sports with persistence and self-control, and develop conscious exercise habits. At the same time, we should also cultivate and master students' various sports skills, physical exercise principles and scientific exercise methods. Students should learn to make exercise plans or "exercise prescriptions" according to their own reality, and master the methods of trauma prevention and self-monitoring.

In order to cultivate students' ability of self-exercise, teachers themselves need to be good examples of self-exercise and healthy fitness. The ancients said: "Give people a fish meal, give people a fish, and benefit for life." This shows the importance of teaching people to fish.

In physical education teaching, there is always one-sidedness, that is, emphasis is placed on imparting sports skills while scientific physical exercise methods are neglected, thus affecting the cultivation of students' self-exercise ability.

(D) Pay attention to the cultivation of creativity

Creativity is the synthesis of various psychological characteristics that can create new theories or new things with social value, and it is an advanced form of intellectual development.

People's creativity is related to people's creative activities, which includes intelligence factors and non-intelligence factors (personality psychological quality). Intelligence factors refer to psychological activities related to cognitive process, while non-intelligence factors refer to psychological activities that do not directly participate in but restrict cognitive process. On the road of talent growth, intellectual factors and excellent qualities complement each other.
