Competitive sports, as a culture formed by long-term practice and tempering in the long history of mankind, has a long history and a broad mass base, and is relatively mature and perfect. The development of school physical education is later than competitive sports, but school physical education is an important part of school education. Although they are different fields of independent development, they are inextricably linked. Based on the relationship between them, this paper puts forward some views and opinions on the means of competitive sports entering school sports.

1 Differences between competitive sports and school sports in concept, object and purpose.

1. 1 Conceptually speaking, school physical education is an educational component that cooperates with morality, intelligence, physique and beauty. It is an educational activity that teachers teach students the "three basics" of physical education, strengthen students' physique, improve sports skills and enrich campus cultural life. Its essence is education and fitness. Competitive sports is a kind of sports entertainment activity, which is competitive, challenging, regular and uncertain. It is a process of body re-creation with competition, competition and competition as its main purposes.

1.2, school sports are ordinary students, and competitive sports are athletes with high degree of sports specialization. The object of school sports has a strong popularity, while the object of competitive sports pursues competitive sports as their own career.

1.3 purpose: school physical education promotes the normal development of students' bodies, while competitive sports pursue the maximum development of athletes' physical potential. The external conditions of school physical education do not allow it to require its objects to achieve maximum physical development like competitive sports, which is not the goal of school physical education. However, the strong competitive characteristics of competitive sports require it to maximize the development of its object's body, which is also one of the necessary prerequisites for its survival. In mastering sports skills, school physical education requires students to use technology for physical exercise to a certain extent, while competitive sports pursue superb skills. Because of the above differences, competitive sports must be integrated into school sports by means, so as to conform to the development law of school sports and meet the development and needs of students.

2. The concept of instrumentalization of competitive sports and the rules that should be followed.

2. 1 Concept: The so-called instrumentalization of competitive sports is the process of processing, transforming, refining and sublimating those complex competitive sports into sports means to enhance physical fitness, improve health and promote the coordinated development of body and mind according to the laws of human development.

2.2 competitive sports means should follow the principles

2.2. 1 Subjectivity principle

The means of competitive sports must be based on effectively promoting students' physical and mental health, and on the premise of cultivating students' needs, interests, abilities and sports foundation, so that competitive sports can serve students to exercise, strengthen their physique and improve their health.

2.2.2 The principle of effectiveness

The instrumentalization of competitive sports is to let students achieve the purpose of fitness and psychological education through sports. The consistency between sports means and health purpose requires that in the process of instrumentalization of competitive sports, components that can effectively exercise and enhance physical fitness should be extracted to form a complete sports means.

Acceptability principle

Most events of competitive sports are not suitable for students' actual exercise and lifelong benefit. Therefore, it is the key to decompose, refine and simplify some technical movements in competitive sports to form sports means, so that students can accept, master and benefit for life through hard work. Of course, those relatively simple competitive sports that are consistent with sports goals and adapt to the characteristics and level of students' physical and mental development can be directly introduced into sports means.

2.2.4 Comprehensive principle

Some competitive sports, after processing and transformation, may only solve some problems of physical development and have certain limitations. Therefore, in the process of exercise, we should cooperate with some physical exercises to ensure the all-round development of the body.

Safety principle

Safety is the premise of health. When dealing with competitive sports by sports means, we must remove those dangerous contents and factors that are prone to injury accidents, so as to nip in the bud.

3 competitive sports means and methods

3. 1 Simplify the technical structure and reduce the difficulty of exercise, so that it can not only enhance physical fitness, improve health, but also reduce the psychological burden of students during exercise.

3.2 Adjust the specifications of venue equipment, modify the rules of competitive competition, and adapt to the reality of students.

3.3 Reduce the load requirements, so that the exercise load can be easily controlled within the optimal threshold to meet the health needs. Instrumentalization of competitive sports, according to the specific requirements of physical education curriculum objectives and learning objectives, following the rules of sports and fitness principles, and on the premise of fully studying and analyzing the fitness of competitive sports, the operability of teachers and the acceptability of students, analyzes the sports from the aspects of sports direction, form, route, distance, sequence, rhythm, difficulty, load, venue, equipment, rules and number of participants. At the same time, it should be supplemented by the optimization of teaching methods and organizational forms to ensure its feasibility and effectiveness. The means of competitive sports should be aimed at different students as far as possible, according to the needs of students' physical and mental development, and purposefully combine modern sports methods such as "fitness exercise prescription" and "roving exercise" to achieve the best fitness effect by competitive sports.

3.4 The instrumentalization of competitive sports can usually be processed, transformed and reconstructed according to a procedure of "decomposition-extraction-change-reconstruction". As far as a certain competitive sport is concerned, we can extract some factors from it, change some factors and discard some factors. Through these extracted and changed factors, we can reorganize and rebuild it, making it more suitable for the physical and mental characteristics of the majority of students, more acceptable to the majority of students, and more able to reflect its fitness.

4. The development trend of competitive sports entering school sports means in the new period.

4. 1 Content diversification

In order to cultivate students' fitness awareness and form the habit of lifelong participation in sports, school physical education in the future society will introduce more competitive sports to students in a planned way on the premise of ensuring the basic teaching content, thus changing the current physical education with track and field as the main content. This can not only stimulate students' interest in learning, but also enable students to choose their own hobbies and sports from many competitive sports, so as to make sports persistent.

4.2 Naturalization of the environment

School physical education in the future society will give students more opportunities to play sports in a fresh natural environment, such as mountain climbing, swimming (rivers, lakes and seas) and cross-country running. Students can not only enhance their physical fitness, but also cultivate their sentiments through contact with nature.

4.3 Scientific Movement

With the progress of science, the development of economy and the increase of school sports funds, the teaching and training of school sports will absorb advanced teaching methods and equipment in the future, so some physiological and biochemical indexes of students' physical condition during and after sports can be monitored at any time, which will provide scientific basis for more scientific arrangement of teaching, training volume, exercise intensity and student health management, thus making school competitive sports more scientific.

4.4 Multistage level

In the future school sports competition, there will be different levels of coexistence. There are general competitive sports that master the "three basics" through physical education teaching; There are also high-level competitive sports that are outstanding in a certain sport through practice. For example, teams in classes or departments, as well as high-level competitive sports, such as competitive sports clubs in schools.

4.5 Socialization and internationalization of communication

In the future, with the improvement of people's living standards and the modernization of transportation, the exchange opportunities between schools in different regions and provinces will increase significantly. At the same time, the relationship between school competitive sports and social competitive sports will be closer. With the deepening of China's reform and opening up, international exchanges will be more frequent in the future, and "twin cities" and "sister schools" will be established.

5 abstract

School physical education shoulders the task of inheriting competitive sports culture and educating students. Without the support of competitive sports, school sports cannot develop, but the popularity of competitive sports in schools in turn promotes its own sustainable development. Therefore, the two promote each other and develop harmoniously.
