运动员非接触性前交叉韧带撕裂在矢状面有共同特征；即身体的质心位于支撑点后方，躯干和膝关节伸展，髋角屈曲。但是，这些变量之间的关系尚未在外地调动中得到评估。这项研究试图确定女性在踢足球时，从颈椎到支撑点的距离与躯干、臀部和膝盖位置之间的关系。使用二维视频分析了60个事件（29个单腿着陆事件和31个单腿停止事件）。采用Pearson积矩相关系数确定各测量变量之间的关系，并采用逐步多元线性回归模型探讨COM位置与运动变量之间的关系。与躯干角度呈中度负相关（r = - 0.623, p < 0.0001, r2 = 0.388），与四肢角度呈显著正相关（r = 0.869, p < 0.0001, r2 = 0.755）。选择四肢、膝关节和躯干角度为最佳回归模型（调整后r2 = 0.953, p < 0.0001, f2 = 20.277）。这些研究结果表明，初始接触时躯干角度的增加和肢体角度的减小与更安全的颈椎位置有关。神经肌肉训练可能有助于在动态活动中控制躯干和下肢的位置。
Abstract Athletes with non-contact anterior cruciate ligament tears have common features in the sagittal plane; namely, the body’s center of mass (COM) is located posterior to the base of support, the trunk and knee joints are extended, and the hip angle is flexed. However, the relationships among these variables have not been assessed in field-based movements. This study sought to determine relationships between distances from the COM to the base of support and the trunk, hip, and knee positions in women while playing soccer. Sixty events (29 single-leg landing and 31 single-leg stopping events) were analyzed using two-dimensional video analysis. The relationships among the measurement variables were determined using the Pearson’s product-moment correlation coefficient, and stepwise multiple linear regression models were used to explore the relationships between the COM position and the kinematic variables. The distance from the COM to the base of support displayed a moderate negative relationship with the trunk angle (r = - 0.623, p < .0001, r2 = 0.388) and a strong positive relationship with the limb angle (r = 0.869, p < .0001, r2 = 0.755). The limb, knee, and trunk angles were selected in the best regression model (adjusted r2 = 0.953, p < .0001, f2 = 20.277). These findings suggest that an increased trunk angle and a decreased limb angle at initial contact are associated with a safer COM position. Neuromuscular training may be useful for controlling the trunk and lower limb positions during dynamic activities.
