背景资料。在体育活动中，女性前交叉韧带非接触性损伤的发生率高于男性。在需要切割任务的运动中，非接触性前十字韧带损伤经常发生。交替的运动控制策略已被确定为非接触性前交叉韧带损伤的潜在危险因素。本研究旨在比较男性和女性休闲运动员在跑步、侧切和横切过程中膝关节运动学和肌电活动的规律。方法收集11名男性和9名女子休闲运动员在跑步、侧切和横切过程中膝关节的三维运动学数据和选定的膝关节肌肉的肌电数据。使用虚拟变量进行回归分析，比较男性和女性之间的膝关节运动模式，结果。在这三种运动任务的站立阶段，与男性相比，女性的膝关节屈曲角度更小，膝关节外翻角度更大，股四头肌激活更大，腿肌激活更低。文献表明，女性这些交替的膝关节运动模式往往会增加前交叉韧带的负荷，结论女性平均可能有某些运动控制策略，这些策略可能会改变她们的膝关节运动模式。在所选的运动任务中，女性膝关节运动模式的改变可能会增加前交叉韧带的负荷，这可能是导致女性前交叉韧带损伤发生率增加的原因之一。
Background. Women have higher non-contact anterior cruciate ligament injury rate than men do in sport activities. Non-contact anterior cruciate ligament injuries frequently occur in sports requiring cutting tasks. Alternated motor control strategies have identified as a potential risk factor for the non-contact anterior cruciate ligament injuries. The purpose of this study was to compare the patterns of knee kinematics and electromyographic activities in running, side-cutting, and cross-cutting between men and women recreational athletes.Methods, Three-dimensional kinematic data of the knee and electromyographic data of selected muscles across the knee joint were collected for 11 men and 9 women recreational athletes in running, side-cutting, and cross-cutting. Regression analyses with dummy variables for comparison of knee motion patterns between men and women,Results. Women tend to have less knee flexion angles, more knee valgus angles, greater quadriceps activation, and lower hamstring activation in comparison to men during the stance phase of each of the three athletic tasks, Literatures suggest these alternated knee motion patterns of women tend to increase the load on the anterior cruciate ligament,Conclusion, Women on average may have certain motor control strategies that may alter their knee motion patterns. Women's altered knee motion patterns may tend to increase the load on the anterior cruciate ligament in the selected athletic tasks, which may contribute to the increased anterior cruciate ligament injury rate among women.
