目的：男性和女性表现出不同的运动模式，这被认为是导致女性前交叉韧带损伤发生率增加的原因。虽然性别差异已被观察到的运动，很少有研究探讨性别差异在不同类型的landings.Design：前瞻性性别比较study.Setting：对照实验室study.Patients：14名男性和14名女性休闲足球运动员被招募为研究。所有受试者进行了足球特定的跳跃头球活动，检查着陆力学的差异之前和之后的足球头球。受试者通过在2个力平台上执行向前跳跃开始任务（落地1）做一个反动作，然后跳起去顶一个挂在测力台上的足球，（着陆2）.主要结果测量：双向方差分析进行（性别x着陆）来检查性别和不同类型着陆对矢状面关节力学的相互作用。结果：髋关节伸展力矩峰值和垂直地面反力存在显著的交互作用，其中男性运动员在第二次着陆时表现出比女性运动员更大的值。男性表现出更大的峰值跖屈和膝关节伸展力矩，但减少峰值髋关节屈曲。登陆的主要影响表现出较低的运动学和较大的动力学值，除了峰值跖屈moment.Conclusions：女性和男性球员出现不同的土地，这取决于登陆的类型。因此，着陆类型的特异性可能是重要的考虑时，筛选损伤的危险因素。临床相关性：本研究探讨了性别之间的差异，在2个不同的着陆任务，并证明了考虑跳跃任务时，筛选个人受伤的危险因素的重要性。
Objective: Men and women exhibit different movement patterns, which are thought to contribute to the increased incidence of anterior cruciate ligament injuries in females. Although gender differences have been observed in movement, few studies have examined gender differences during different types of landings.Design: Prospective gender comparison study.Setting: Controlled laboratory study.Patients: Fourteen male and 14 female recreational soccer players were recruited for the study. All subjects performed a soccer-specific jump heading activity to examine differences in landing mechanics before and after heading the soccer ball. Subjects began the task by performing a forward jump onto 2 force platforms (landing 1) and conducting a countermovement before jumping up to head a soccer ball that was hanging above the force platform before, then landing back on the force platforms (landing 2).Main Outcome Measures: A 2-way analysis of variance (gender x landing) was performed to examine the interaction between gender and different types of landings on sagittal plane joint mechanics.Results: Significant interactions existed for the peak hip extension moment and vertical ground reaction force where the male players exhibited increased values during the second landing compared with the female players. Males exhibited greater peak plantarflexion and knee extension moments, but decreased peak hip flexion. Main effects for landing exhibited lower kinematic and larger kinetic values except for the peak plantarflexion moment.Conclusions: Female and male players appear to land differently depending on the type of landing. Therefore, specificity of landing type may be important to consider when screening for injury risk factors.Clinical Relevance: This study examines the differences between genders during 2 different landing tasks and demonstrates the importance of considering the jumping task when screening individuals for injury risk factors.
