健康女性和男性的躯干和下肢运动学之间的关系尚不清楚，因为在额面和横面上的躯干运动学还没有得到系统的下肢运动学研究。本研究的目的是调查不同性别的人在单腿蹲下时是否存在不同的多关节运动策略。我们预计，与男性相比，女性躯干和骨盆的移位会更大，因为躯干控制较少，并且在负重肢体上表现出与内收(即更大的髋关节内收、髋关节内侧旋转、膝关节外展、膝关节外侧旋转)一致的髋关节和膝关节运动。9名女性和10名男性参与了这项研究。运动学数据是使用8个摄像头的3D运动捕捉系统收集的。在与膝关节力学有关的两个时间事件：屈膝45°和屈膝峰值时，测量躯干相对于骨盆、骨盆相对于实验室、髋关节和膝关节在三个平面(矢状面、额面角和横面角)的角度。女性的躯干弯曲程度低于男性，躯干和骨盆向负重肢体的旋转程度高于男性。女性也比男性表现出更大的髋关节内收和膝盖外展。综上所述，这些结果表明，女性和男性在单腿蹲下时使用不同的运动策略。女性的躯干和骨盆运动模式可能会使她们面临膝盖受伤和疼痛的风险。
The relationship between trunk and lower limb kinematics in healthy females versus males is unclear since trunk kinematics in the frontal and transverse planes have not been systematically examined with lower limb kinematics. The aim of this study was to investigate the existence of different multi-joints movement strategies between genders during a single leg squat. We expected that compared to males, females would have greater trunk and pelvis displacement due to less trunk control and display hip and knee movement consistent with medial-collapse (i.e. greater hip adduction, hip medial rotation, knee abduction, knee lateral rotation) on the weight-bearing limb. 9 females and 10 males participated in the study. Kinematic data were collected using an 8-camera, 3D-motion-capture-system. Trunk relative to pelvis, pelvis relative to the laboratory, hip and knee angles in three planes (sagittal, frontal and transverse) were examined at two time events relevant to knee joint mechanics: 45° of knee flexion and peak knee flexion. Females flexed their trunk less than males and rotated their trunk and pelvis toward the weight-bearing limb more than males. Females also displayed greater hip adduction and knee abduction than males. Taken together these results suggest that females and males used different movement strategies during a single leg squat. Females displayed a trunk and pelvic movement pattern that may put them at risk of knee injury and pain.
