INTRODUCTION
With the continuous deepening of the reform process of school physical education teaching and sports training, the comprehensive promotion of quality education, the implementation of the new goals of physical education curriculum standards and training syllabus, the concept of "health education" has penetrated into physical education teaching, and the national traditional sports have been popularized to a certain extent in school physical education teaching. 1National traditional sports is a special group in sports.In its unique sports mode, it pays attention to national feelings, national spirit and national theory, as well as the natural integration of aesthetic objects and aesthetic subjects with national style, which makes national traditional sports full of charm and vitality. 2However, due to the special technical requirements of various sports, the key points of special sports movements are not well mastered, which violates the characteristics of body structure and function and the biomechanical principle during sports, thus constituting the inducing factors that can cause sports injury. 3The National Traditional Sports entered the school physical education system relatively late, and a scientific and systematic training system has not been established.Moreover, the training of traditional sports is restricted by many factors, and the probability of sports injury accidents is high. 4By studying the causes, preventive measures, treatment effects and rehabilitation time of sports injuries, it is beneficial to improve the sports conditions, improve teaching and training methods, and promote the physical and mental health of physical exercisers. 5Sports is one of the important contents of school education and plays an irreplaceable role in cultivating students' comprehensive quality.Through physical education and extracurricular sports activities, the purpose of strengthening students' physique and improving students' quality is realized. 6However, sports is a teaching activity that is prone to injury.Even minor injuries that occur in the process of sports may have a serious impact on their studies and even their life, and even affect their physical health, which is not conducive to the normal progress of students' learning and life. 7

Definition and classification of sports injuries
Sports injuries are injuries that occur to the body under the influence of a variety of factors during physical exercise and participation in sports. 8mong all sports injuries, joint sprains accounted for 38.15%, abrasions accounted for 25%, and contusions accounted for 18%.But no matter what kind of sports trauma, it will cause physical and psychological pain to the trauma victim, and even cause lifelong disability.The economic loss and social impact caused by sports trauma have been paid more and more attention.After sports injury occurs, timely treatment is very important. 9f the treatment of acute sports injury is not timely and the treatment effect is not good, it will evolve into an old injury, which will prolong the course of the injury and affect the physical and mental health of athletes. 10ccording to the degree of injury, it is divided into minor injury, moderate injury and serious injury.According to the nature of sports injury: (1) Open injury: there is a wound communicating with the outside world and accompanied by bleeding, the skin is abraded, and its integrity is destroyed.Such as abrasions, wounds and fractures.(2) Closed injury: no rupture wound, skin intact, no bleeding.Such as contusion, joint muscle ligament strain, sprain, closed fracture and joint dislocation.According to the relationship between sports technology and training, it can be divided into: (1) Sports technical injury: this injury is closely related to the characteristics of sports technology.A few are acute injuries, such as humerus fracture and Achilles tendon fracture during throwing, ligament tension and muscle fiber tear during jumping, and most are strain injuries, such as tennis elbow, patellar tendinitis and tendinitis.
(2) Non sports technical injury: injury caused by indirect or direct violence.In conclusion, classification of sports injuries is conducive to understanding the sports injuries and timely observation and treatment.

Analysis of the causes of national sports injuries
Due to its particularity, ethnic sports are prone to sports injuries.The main causes of injuries are analyzed as follows: 1. Lack of awareness of prevention.On the one hand, people who participate in sports fail to pay attention to the importance of preventing sports injuries due to their weak awareness of prevention.Therefore, they do not participate in sports events in accordance with the sports requirements, norms and standards, which increases the risk of sports injuries.On the other hand, the weak awareness of sports injury prevention will also make participants ignore the preparations before sports.The technical action is not standard.2. Compared with mass sports, traditional national sports have many specific training skills and action essentials.Blind training is extremely easy to cause damage if it is not standardized and guided.Excessive exercise will lead to physical and mental intolerance.3. The daily physical training can not bear a large amount of exercise, its muscle elasticity and basic strength are poor, the reaction is slow during the exercise, and the flexibility of the body joints is insufficient.Therefore, during the exercise, there will be sports injuries due to the body itself.

Influence of sports injuries on physical fitness
There are many factors that affect the physique, such as heredity, living habits, interests and hobbies, will quality, education system, facilities construction, campus culture, social atmosphere, utilization of sports resources, monitoring and evaluation of sports, and national policies and systems, all of which are factors that affect the physique of students.Among them, physical exercise in schools can most effectively enhance students' physique.
The participation of young students in sports can not only improve their physical fitness, but also make the various functions of the body more active.It is also conducive to the development of the height, weight, vital capacity, flexibility and nervous system of young people.Therefore, schools should urge students to take more sports, and schools should also hold some activities to encourage students to actively participate.However, according to the classification of sports injuries mentioned in Section 2.1, sports injuries are closely related to the physical quality of college students.If the treatment is not timely and the treatment effect is not good, it will have different negative effects on the body and mind of college students.

Research objects and methods
In this paper, a total of 312 college students from 10 colleges and universities in a city who regularly participate in various national sports events are taken as the research objects to investigate the common sports injuries they encounter in the process of participating in national sports activities, and analyze the main injury factors using statistical methods.According to the survey on whether sports injuries have occurred during training or competition, 284 students have suffered from injuries of varying degrees in the course of sports, and 28 students have never suffered injuries, with an injury rate of 91.02%.This indicates that most of the surveyed college students have suffered sports injuries during training or competition.(Table 1)

Findings
In order to test the reliability of the questionnaire, this paper uses the "retest reliability method" to retest a small part of the respondents.The correlation coefficient of the two tests is calculated as R = 0.85, which indicates that the survey results have high reliability.
It can be seen from Table 2 that the proportion of sports injuries caused by poor self-protection ability and inadequate preparation activities of students is also relatively large.Incorrect technical movements and poor physical quality of students are also problems that cannot be ignored in sports training in Colleges and universities.On the one hand, the muscle strength is poor, and the flexibility and stability of joints are weak, so it is easy to be injured.On the other hand, the special technology is not comprehensive and the action is not standardized, which violates the physical structure, functional characteristics and physiological principles during sports, thus causing sports injury.In addition, the injury caused by insufficient preventive measures and lack of active treatment and medical supervision should also be noticed.
It can be seen from Table 3 that among the sports injury sites during training or competition, the investigated 312 athletes mainly suffered from the lower limbs, accounting for 71% of the total number, followed by the fingers and shoulders, accounting for 25% and 4% respectively.The head sports injury is less.(Table 3, Figure 1) In conclusion, it is suggested that college students and physical education teachers should constantly summarize and study more scientific and reasonable training methods in national sports competitions or training, and strengthen the arrangement and revision of training plans for the main injury parts.At the same time, we should further study the competition rules and methods, and use the relevant knowledge of sports human science to guide the training, so as to reduce the incidence of injury.Secondly, we should strengthen students' self-protection consciousness, pay attention to the preparatory activities, strengthen medical supervision, eliminate sports fatigue and reduce sports injury in time.

CONCLUSIONS
College sports curriculum has a direct impact on students' physique and health, and is the core factor to enhance college students' physical quality and comprehensive development of physical and mental health.Based on the research on the influence of physical exercise on students' physique and health, colleges and universities should strengthen the practice of physical education courses and improve the education level of physical education.The combination of national sports and physical education courses should strictly follow the guiding ideology of taking students as the center.Teachers should pay attention to students' physical health, take students' physical health test results as the basis, and combine the diversity of physical education courses to achieve the high efficiency of course teaching.Colleges and universities should create an atmosphere of "relaxed, harmonious and positive" sports activities, increase investment in sports, improve sports teaching conditions, carry out sunshine sports from multiple directions and channels, establish and improve a long-term supervision mechanism, implement sunshine sports and actively prevent sports injuries, so as to promote the improvement of College Students' physical health through various effective ways.
