In this article, we focus on the injury characteristics of youth athletes. First, we organize the physical characteristics of children during adolescent growth. Next, grasp the actual condition of injury of youth athlete in Japan. Finally, we summarize activities of sports organizations in Japan on injury prevention of youth athletes who are drawing the attention of sports orthopedic surgeons. During growth spurt phase, children have structurally fragile parts such as epiphysis and epiphyseal line, whose body structure is different from adults. The characteristic of sports injuries during the growth spurt phase occurs due to the fact that the growth of tissues such as the increase in bone mass and surrounding muscle tendons slightly lag against rapid bone growth. The sports injury is a summary of the traumatic injury in which the tissue is damaged by a major external force and the overuse injury in which the tissue gradually becomes damaged due to repeated minor external forces. Youth athletes often cause fractures and sprains in trauma and often develop osteochondrosis or stress fractures in overuse injury. In this study, individual body maturity is not taken into consideration, and it is caused by exercise practice in the physical disparity and over training due to load not matching body maturity. It is important in prevention of sports injuries to change the conditioning method, training and coaching method based on body maturity.
