Triple jump is the strengths Track and Field Events in Hebei Province. In recent years, Wu Ji, Li Yanxi and Cao Shuo win the gold medal for four consecutive years, showing Hebei’s strong position in triple jump. In order to ensure Hebei’s triple jump long time strong and successors can take over their predecessors, training triple jump athletes is even more important. However, athletes and coaches are nagged by sports injury. Sports injuries directly affect athletic ability, the normal athlete’s training and competition, performance of athletes, coaches’ plan, and even affect the athlete’s career. So to do scientific training, to reduce injuries, and to prevent athletes from the sport injury are the sustainable development of Hebei’s critical needs of the event, but also the need to maintain a high ability of Hebei’s triple jump athletes. By doing these, more high-level sports talents can be conveyed to Hebei Province and even to our nation.In this thesis, the author adopts the following methods: literature, survey method and mathematical statistic method. The survey method includes interviewing athletes, coaches and experts, questioning athletes and coaches, experiencing as an assistant coach with a training team.The author draws the following conclusions by investigating coaches and juvenile triple jump athletes in sports schools of Baoding, Tangshan, Xingtai and Shijiazhuang in Hebei Province.By investing 62 Hebei juvenile Sports School triple jump athletes, the author finds out 48 of them who has occurred athletes injury. The injury rate is 77.4%, which is a very high rate.Juvenile sports injuries’ emergence relates to training levels, training age, training season and training content. The rate of juvenile sports injuries over level 2 is higher than under level 2. Athletes training less than 2 years seldom occur the sport injury. Most athletes get sports injury after entering the sports school two years. In spring and winter the sport injury occurs more. In technical training, juvenile triple jump athletes are most prone to be injured.The main reason causing the juvenile triple jump athletes injuries are errors in technical action, unskilled technical movements and over fatigue. In the interview, the coaches consider that the technical movements and exercise load are the two causes of the sport injury.Currently, the six sports schools that investigated in the study lack reasonable medical supervision and treatment mechanism. Among the six schools only Hebei Province Sports School detects clothing for a period of time, while others are not available to this detection. Thus the author concludes juvenile triple jump athletes are lack of knowledge and skills of sports injuries and even lack of sports injuries treatment.Through these studies, we revisit coaches and make some relevant views on the basis of references and the specific circumstances of the six sports schools, and you can make the following recommendations:Coaches should arrange reasonable training events.Improve and perfect the technical action adolescent athlete’s triple jump, the right technological action is in line with the science of human movement, which can effectively prevent and reduce sports injuries.Fully enhance the juvenile triple jump athletes’ physical fitness, because good physical fitness is the basis of the prevention of the sport injury.Each sports school should establish a sound system of medical supervision and organize the athletes to learn some knowledge about sports injury to implement the "prevention first" concept.
