INTRODUCTION
School physical education is an essential part of school education.The quality of school physical education directly affects Chinese high-level talent training and national physical fitness.School sports can invigorate the cultural life of students and have the function of enhancing students' physical fitness.As the frequency and intensity of school sports activities continue to increase, accidental injuries occur from time to time during sports. 1 Accidental injuries may harm the health of the body and may cause sudden death and disability of students.Therefore, it has a significant impact on school physical education.How to prevent and reduce the occurrence of sports injury accidents of college students has become the main problem that needs to be solved urgently in school sports work.

Research object
The thesis takes sports injury accidents and risks prevention and control of college students as the research object.

Literature data method
We searched the CNKI database with keywords such as "college student sports injuries" and "school sports risk prevention and control." We found a total of 31 articles about college students' sports injury accidents and a total of 14 articles about school sports risk prevention and control. 2 By searching such documents, we can understand the current causes of college students' sports injury accidents and the prevention and control of school sports risks.

Questionnaire survey method
A total of 800 student questionnaires were distributed.800 copies were recovered, and the recovery rate was 100%.37 invalid questionnaires were eliminated, and 763 valid questionnaires were obtained. 3he effective recovery rate is 95.4%.A total of 16 expert questionnaires were distributed.Each school-issued 2 copies and recovered 16 copies.The effective recovery rate was 100%.

Mathematical Statistics
Data statistics use SPSS17.0Chinese version application software to perform statistical processing on the collected data using frequency analysis in descriptive analysis.

Establishing a sports injury model of athletes' bone joints
When analyzing the sports injuries of athletes' bones and joints, we first obtain the mutual information between the characteristics of the factors that lead to bone and joint injuries in training.The article establishes the system principal model of an athlete's bone and joint injury. 4The specific steps are detailed below: Suppose that B represents the bone and joint injury feature space v.The hurdle training on the bone and joint injury sample data set.∂ represents the original bone and joint injury sequence.ξ represents the training time sequence of the athletes.ρ represents the feature vector corresponding to the feature value of the bone joint.We use formula (1) to obtain the mutual information between the characteristics of the bone and joint damage factors during training S represents the cost function that causes damage to the athlete's bones and joints.l represents the maximum energy produced by the bones and joints when the body moves.Φ represents the athlete's maximum training load.j represents the marginal probability distribution of the injury factor characteristics of the bone and joint.k represents the joint probability distribution of the injury factor characteristics of the bone and joint.Ψ represents the mutual information between the characteristics of the two bone and joint injury factors.k represents the principal component of the damage factor. 5We use the eigenvalues of the mutual information matrix of bone and joint injury factors as the evaluation criterion to determine the number of principal components that affect the bone and joint injury by hurdle training.We use formula (2) to express Ʌ(W) represents the information of the original bone and joint injury variables.ɩ(k) represents the characteristics of bone and joint sports injuries.ϕ(ρ) represents the correlation matrix of each bone and joint injury factor.We use formula (3) as the basis and use formula (4) to establish a system principle model of athletes' bone and joint injury The formula λ represents the maximum intensity load that can be borne under normal bone and joint motion.When we use the system principle model of athlete's bone and joint injury to analyze the impact of the characteristics of bone and joint sports injury, it is necessary to study the law between hurdle training and bone and joint injury.

Number of sports injury accidents among college students
Among the students surveyed, 321 students have had sports injuries during their time at school, accounting for 42.1% of the surveyed subjects.Among them, 166 students had suffered a sports injury accident, accounting for 21.8% of the surveyed subjects. 794 students have suffered two sports injury accidents, accounting for 12.3% of the surveyed number.61 students who have suffered 3 or more sports injury accidents, accounting for 8% of the surveyed number.

Male to female ratio of college students in sports injury accidents
The survey results reflect that among college students who have had sports injuries in colleges and universities, both the number and frequency of injuries among boys are much higher than those of girls (Table 1).Injury accidents occurred in sports activities in different sports scenes The extracurricular sports activities carried out by individual students have the highest probability of sports injury accidents, with 168 people.This accounts for 52.3% of the number of students who have experienced sports injury accidents.Ranked second is the sports activities organized by the school, with 134 people.This accounts for 41.7% of the number of students who have suffered injuries. 8The lowest incidence of sports injury accidents is in physical education, with 80 people.This accounts for 24.9% of the number of students who have suffered injuries.

Causes of injury accidents in a physical education class
In the physical education class, the main reason for the injury of middle school students is the lack of self-protection consciousness.This accounts for approximately 93.8%.Due to the aging of school premises and equipment, there are hidden safety hazards that caused 31.3% of college students to be injured.Teachers did not provide adequate education for them, and the reasons for the student's injuries were 12.5% of the reasons that the safety protection measures were not enough.There are 5% of the reasons that students have potential diseases or have congenital diseases and injuries.

Reasons for injuries in sports competitions or sports organized by the school
It can be seen from Table 2 that the number one cause of sports injury accidents is that students do not abide by the rules of the game, accounting for about 84.3%.The second is that the school is negligent in management and does not have full safety measures.This accounts for about 73.1%; the third place is that sports competitions are too intense.Students from 58.2% in frequent collisions; the last is the aging of school facilities and potential safety hazards.This accounts for approximately 11.9%.The existence of various uncertain factors in sports competitions or sports meets organized by the school will cause college students' sports injury accidents.

Analysis of the status quo of risk prevention and control in college sports
The establishment of a sports risk prevention and control mechanism It can be seen from Table 3 that only one university has established a relatively complete sports risk prevention and control mechanism.The establishment of sports risk prevention and control mechanisms in 6 colleges and universities is continuously improved.However, one university has not yet begun to establish a sports risk prevention and control mechanism.
The establishment of the sports risk prevention and control system and the handling plan for sports injury accidents Only one private college among the eight colleges and universities investigated has established a plan for handling school sports accidents.Five private colleges and universities have more or less established plans for handling school sports accidents.However, there are still two private colleges and universities that have not yet begun establishing a sports accident handling plan.

Purchase of sports equipment
It can be seen from Table 4 that among the 8 colleges and universities surveyed, 7 private colleges and universities purchase sports equipment and facilities following national standards.Only one private college did not purchase school sports equipment and facilities following national standards.

DISCUSSION
Extracurricular activities carried out by students, or sports activities organized by the school (sports games or sports competitions) are areas with a high incidence of sports injury accidents.The main reason is that students lack practical preparation activities and self-protection during extracurricular sports activities or school-organized sports activities (sports games or sports competitions).When the sport reaches the excitement point, students will forget to protect themselves, prevent themselves, and cause sports injuries.In addition, extracurricular sports activities or school-organized sports activities are mainly group events and contentious events.This kind of project is more competitive, which exacerbates the students' eagerness to compete, and it is easy to neglect the protection of themselves and their opponents.This is more prone to sports injuries.
The main reason for the injury accidents of students in physical education is the lack of self-protection awareness, and the second is the aging of school grounds and equipment.Therefore, self-protection methods are taught in physical education classes to improve students' self-protection awareness.We need to speed up the update of sports equipment.It is essential to strengthening the pre-class inspection.

CONCLUSION
The proportion of sports injuries among college students is relatively high.The proportion of personal injuries in extracurricular sports activities carried out by individual students is the highest, and the proportion of injuries in physical education is the lowest.The main reason for college students' sports injuries is their factors.The construction of the sports risk prevention and control mechanism in colleges and universities is not perfect.The awareness of sports risk prevention and control is lacking, and the relevant insurance purchase mechanism is not sound.The control measures and the maintenance and management of school sports facilities and facilities are better.
