- 概要
- Skiing is associated with a high incidence of anterior cruciate ligament (ACL) injury. A higher incidence of ACL injuries in female skiers has been reported, similar to that in other sports; a previous study also reported a higher incidence of ACL injury in junior female skiers. Dynamic alignment of the leg is considered a risk factor for ACL injury. However, no reports have examined sex-related differences in dynamic alignment of junior athletes. Therefore, this study aimed to investigate the sex-related differences in dynamic alignment of the lower extremities as a risk factor for ACL injury in national top-level junior skiers. In total, 52 legs of 26 skiers (28 legs of 14 male junior skiers and 24 legs of 12 female junior skiers) were evaluated. The skiers performed drop vertical jump (DVJ) and single-leg squat (SLS). Frontal, sagittal, and horizontal plane images of their posture during DVJ and SLS were obtained. From these images, the joint angles of the lower extremities in the frontal and sagittal planes were calculated. The knee valgus angle at DVJ and SLS was significantly greater in female junior skiers than in males (p<0.001 and p<0.05, respectively). As knee valgus is a risk factor for ACL injury, dynamic alignment of junior female skiers seems to be improved to prevent ACL injury.
