چکیده:
Introduction: Nowadays, the use of artificial turf fields has become widespread. Given the high prevalence of noncontact injuries among female soccer players and high contribution of the Anterior Cruciate Ligament (ACL) injury, this research was conducted to compare biomechanical risk factors in the incidence of ACL injury for elite female soccer players during shearing maneuver and header on the natural grass and artificial turf fields. Methods: Sixteen players were selected from U-14 women’s national team by the convenience sampling method and started to perform the skills. Knee joint information was calculated by a 3D imaging system and a force plate. Statistical differences were reported using the dependent t-test at a significant level of 0. 05. Results: The findings showed that the biomechanical behavior of the lower extremity while performing soccer skills on the natural grass was affected differently from that on the artificial turf. Results also demonstrated that the torque applied to the knee joint on the natural grass was higher than that on the artificial turf (P=0. 039). Angular velocity on the artificial turf was also higher than that on the natural grass (P=0. 006). Conclusion: The higher knee joint torque and the lower angular velocity on natural grass may result in a higher risk of ACL injury on the natural grass than on the artificial turf. Therefore, the use of prevention programs for ACL injury is crucial to minimize the incidence of lower extremity injuries.
استفاده از زمینهای چمن مصنوعی بطور وسیعی افزایش یافته است. با توجه به شیوع بالای اسیبهای غیربرخوردی در فوتبالیستهای زن و سهم بالای اسیب رباط صلیبی قدامی (ACL)، این تحقیق با هدف مقایسه عوامل خطر بیومکانیکی در وقوع اسیب ACL فوتبالیستهای زن نخبه حین اجرای مانور برشی و هد زدن در دو سطح چمنطبیعی و مصنوعی انجام گرفت. 16 نفر از بازیکنان تیم ملی نونهالان بانوان به صورت نمونه در دسترس انتخاب شدند و به اجرای مهارتها پرداختند. اطلاعات مربوط به مفصل زانو توسط سیستم تصویربرداری سه بعدی و صفحه نیرو محاسبه شد. تفاوت اماری با استفاده از ازمون تی وابسته در سطح معناداری 0. 05 گزارش شد. یافتهها نشان داد رفتار بیومکانیکی اندام تحتانی هنگام اجرای مهارتهای فوتبال روی چمنطبیعی بطور متفاوتی از چمنمصنوعی تحت تاثیر قرار میگیرد. یافتهها نشان داد گشتاور وارد بر مفصل زانو در چمنطبیعی بالاتر از چمنمصنوعی است (0/039= p ). همچنین سرعت زاویهای روی چمن مصنوعی نسبت به چمن طبیعی بالاتر بود (0/006= p ). این عوامل باعث میشود تا خطر احتمال وقوع اسیب ACL در چمن طبیعی بالاتر از چمن مصنوعی باشد.. بنابراین بکارگیری برنامههای پیشگیری از اسیب ACL جهت بحداقل رساندن وقوع اسیب از اهمیت بالایی برخوردار است.

Comparing Biomechanical Risk Factors of Anterior Cruciate Ligament Injury of Elite Female Soccer Players During the Shearing Maneuver and Header on the Natural Grass and Artificial Turf.
Given the high prevalence of noncontact injuries among female soccer players and high contribution of the Anterior Cruciate Ligament (ACL) injury, this research was conducted to compare biomechanical risk factors in the incidence of ACL injury for elite female soccer players during shearing maneuver and header on the natural grass and artificial turf fields.
Considering the high prevalence of ankle and knee injuries due to shearing and jumping motions in sports like soccer, the study of lower extremity joints while performing these skills could be beneficial to understand the risk factors of in- juries.
