女性运动员被认为表现出膝关节和躯干运动，这是前交叉韧带（ACL）损伤的特征。本研究的目的是检查在体内运动的躯干和膝关节在切割操作，并确定它们之间的关系。所有参与者（10名男性和10名女性大学生运动员）进行了穿梭运行切割任务与左肢体。计算躯干倾斜度（向前和侧向）和膝关节角度（屈曲/伸展、外展/内收和胫骨内/外旋）。研究了性别之间的差异以及膝关节运动和躯干倾斜度之间的关系。躯干前倾的增加与膝关节屈曲角度的增加密切相关，与胫骨内旋偏移的减少中度相关。右躯干外侧倾斜度的增加与胫骨内旋偏移的增加中度相关。结果还表明，性别之间的躯干前倾，侧倾，膝关节屈曲角度的差异，但没有这样的差异，在膝关节外展或内部胫骨旋转。躯干倾斜度与膝关节屈曲和胫骨内旋偏移有关。女性运动员表现出较低的躯干前倾和膝关节屈曲角度，这种姿势类似于ACL损伤。
Female athletes are considered to exhibit knee and trunk motion that is characteristic of anterior cruciate ligament (ACL) injury. The aim of this study was to examine the in vivo motion of the trunk and knee during a cutting manoeuvre and determine the relationship between them. All participants (10 male and 10 female college athletes) performed a shuttle run cutting task with the left limb. Trunk inclination (forward and lateral) and knee joint angles (flexion/extension, abduction/adduction, and internal/external tibial rotation) were calculated. Differences between the sexes and associations between knee motion and trunk inclination were examined. An increase in trunk forward inclination was strongly correlated with an increase in knee flexion angle and moderately correlated with a decrease in the excursion of internal tibial rotation. An increase in right trunk lateral inclination was moderately correlated with an increase in excursion of internal tibial rotation. The results also showed differences between the sexes in trunk forward inclination, lateral inclination, and knee flexion angle, but no such differences in knee abduction or internal tibial rotation. Trunk inclination is related to knee flexion and excursion of internal tibial rotation. Female athletes demonstrate a low trunk forward inclination and knee flexion angle, a posture that resembles that of ACL injury.
