Female runners are reported to be more prone to develop specific knee joint injuries than males. It has been suggested that increased frontal plane joint loading might be related to the incidence of these knee injuries in running. The purpose of this study was to evaluate if frontal plane knee and hip joint kinematics and kinetics are gender-specific in runners with high mileage. 3D-kinematics and kinetics were recorded from 16 female and 16 male runners at a speed of 3 m/s, 4 m/s, and 5 m/s. Frontal plane joint angles and joint moments were ascertained and compared between genders among speed conditions. Across all speed conditions, females showed increased hip adduction and reduced knee adduction angles compared to males (p < 0.003). The initial peak in the hip adduction moment was enhanced in females (p = 0.003). Additionally, the hip adduction impulse showed a trend towards an increase in females at slow running speed (p = 0.07). Hip and knee frontal plane joint kinematics are gender-specific. In addition, there are indications that frontal plane joint loading is increased in female runners. Future research should focus on the relationship of these observations regarding overuse running injuries.
据报道，女性跑步者比男性更容易患上特定的膝关节损伤。有人认为，前平面关节负荷增加可能与跑步中这些膝关节损伤的发生率有关。本研究旨在评估高里程跑步者的膝关节和髋关节在前平面的运动学和动力学是否具有性别特异性。在 3m/s、4m/s 和 5m/s 的速度下，从 16 名女性和 16 名男性跑步者中记录了 3D 运动学和动力学。在速度条件下，确定并比较了性别之间的前平面关节角度和关节力矩。在所有速度条件下，与男性相比，女性的髋关节内收角度增加，膝关节内收角度减小（p < 0.003）。女性髋关节内收力矩的初始峰值增强（p = 0.003）。此外，女性在慢跑步速时髋关节内收冲量呈增加趋势（p = 0.07）。髋关节和膝关节的前平面关节运动学具有性别特异性。此外，有迹象表明女性跑步者的前平面关节负荷增加。未来的研究应集中在这些关于过度使用跑步损伤的观察结果的关系上。
