Abstract: Analysis of 58 cases of sports injuries in school shows that competing events in the same field has the highest rate of incidence, and the highest probability of sports mainly happens in junior middle school and therefore the percentage of school liability is higher than the others. Sports inherent risk is the intrinsic factor of sports injuries in primary and secondary schools. The prevention and control system of school injury is not sound, sports venues and facilities are flawed, sports teachers fail to fulfill their duties, and students' lack of risk prevention and control abilities are the main external factors that induce the accidents. The principle of fault liability and the principle of fair liability are beneficial supplements to the economic loss of accidents. The paper puts forward 15 precaution measures including 5 for school management, 5 for PE class, 2 for extra curriculum sports activities, and 3 for sports training and competition.
