Deficits in movement patterns during cutting while running might place soccer players at risk of injury. The objective was to compare joint angles and intersegment coordination between sexes and ages during an unanticipated side-step cutting task in soccer players. This cross-sectional study recruited 11 male (four adolescents and seven adults) and 10 female (six adolescents and four adults) soccer players. Three-dimensional motion capture was used to measure lower-extremity joint and segment angles as participants performed an unanticipated cutting task. Hierarchical linear models examined relationships between joint angle characteristics with age and sex. Continuous relative phase was used to quantify intersegment coordination amplitude and variability. These values were compared between age and sex groups using analysis of covariance. Adult males had greater hip flexion angle excursions than adolescent males, while adult females had smaller excursions than adolescent females (p = .011). Females had smaller changes in hip flexion angles (p = .045), greater hip adduction angles (p = .043), and greater ankle eversion angles (p = .009) than males. Adolescents had greater hip internal rotation (p = .044) and knee flexion (p = .033) angles than adults, but smaller changes in knee flexion angles at precontact compared with stance/foot off (p < .001). For intersegment coordination, females were more out-of-phase than males in the foot/shank segment in the sagittal plane. There were no differences in intersegment coordination variability between groups. Differences in joint motion during an unanticipated cutting task were present between age groups and sexes. Injury prevention programs or training programs may be able target specific deficits to lower injury risk and improve performance.
在跑步过程中进行变向切割时运动模式的缺陷可能会使足球运动员面临受伤的风险。本研究旨在比较足球运动员在进行非预期侧步切割任务时，不同性别和年龄组间的关节角度和体段间协调性。本横断面研究招募了 11 名男性（4 名青少年和 7 名成年人）和 10 名女性（6 名青少年和 4 名成年人）足球运动员。参与者在进行非预期切割任务时，使用三维运动捕捉来测量下肢关节和体段角度。分层线性模型检验了关节角度特征与年龄和性别的关系。连续相对相位用于量化体段间协调性的幅度和可变性。使用协方差分析比较了年龄和性别组之间的这些值。成年男性的髋关节屈曲角度比青少年男性大，而成年女性的髋关节屈曲角度比青少年女性小（p =.011）。女性的髋关节屈曲角度变化较小（p =.045），髋关节内收角度较大（p =.043），踝关节外旋角度较大（p =.009），而男性则较大。青少年的髋关节内旋（p =.044）和膝关节屈曲（p =.033）角度比成年人更大，但在预接触到支撑/脚离地阶段，膝关节屈曲角度的变化较小（p <.001）。在体段间协调性方面，女性在矢状面中足部/小腿段的相位滞后大于男性。组间体段间协调性的可变性没有差异。在非预期切割任务中，关节运动在不同年龄组和性别间存在差异。损伤预防计划或训练计划可能能够针对特定的缺陷，降低受伤风险并提高表现。
