چکیده
مقدمه و اهداف: سطح عامل مهمی است که ممکن است بر خطر آسیب‌دیدگی در حین دویدن تأثیر بگذارد. هدف از مطالعه حاضر، مقایسه نیروهای وارده بر پا طی دویدن بر روی سطح زمین در مقایسه با چمن مصنوعی در افراد با پای پرونیت و سوپینیت بود.

مواد و روش‌ها: جامعه آماری پژوهش حاضر را مردان دارای پای پرونیت و سوپینیت و سالم استان اردبیل تشکیل دادند. نمونه آماری به تعداد 30 نفر با دامنه سنی 25-20 سال به روش نمونه­گیری در دسترس انتخاب و در مطالعه حاضر شرکت کردند. نمونه­های آماری در سه گروه قرار گرفتند. تعداد 10 نفر در گروه پای پرونیت، 10 نفر در گروه پای سوپینیت و گروه سوم که 10 نفر هستند به‌عنوان گروه کنترل قرار گرفتند. از روش افتادگی استخوان ناوی برای تعیین نوع پا استفاده شد. از صفحه نیرو برتک برای ثبت نیروی عکس‌العمل زمین در هنگام دویدن بر روی سطح زمین و چمن مصنوعی با سرعت 2/3 متر بر ثانیه استفاده گردید. همچنین نیروهای عکس‌العمل زمین در جهت­های عمودی (Fz)، قدامی-خلفی (Fy) و داخلی-خارجی (Fx) اندازه­گیری شد.

یافته‌ها: در فاز برخورد پاشنه پا با زمین مؤلفه داخلی-خارجی نیروی عکس‌العمل زمین در افراد دارای پای پرونیت طی دویدن بر روی سطح زمین در مقایسه با سطح چمن بزرگ‌تر بود. بعلاوه در لحظه برخورد پاشنه پا با زمین زمان رسیدن به اوج مؤلفه عمودی نیروی عکس‌العمل زمین طی دویدن بر روی چمن در مقایسه با سطح زمین افزایش یافت.



نتیجه ­گیری: باتوجه‌به یافته­ها می­توان نتیجه گرفت که استفاده از سطح چمن مصنوعی می­تواند موجب بهبود ریسک فاکتورهای آسیب در افراد دارای عارضه پای پرونیت و سوپنیت شود.

چکیده English

Background and Aims: The surface quality and type are an important factor that may influence the risk of sustaining injuries during running. The aim of the present study was to compare forces excreted on the foot while running on the ground and artificial turf in people with pronated and supinated feet.

Materials and Methods: The statistical population of the present study consisted of healthy men with pronated and supinated feet in Ardabil province. A statistical sample of 30 people aged 20-25 years was selected by available sampling and participated in the present study. Statistical samples were divided into three groups. There were 10 patients in the pronated foot group, 10 people in the supinated foot group and the third group of 10 people as the control group. The navicular drop test was used to measure foot type. A Bertec force plate was used to record ground reaction forces while running on ground and artificial turf at constant speed (about 3.2 m/s). The ground reaction forces in the vertical (Fz), anterior-posterior (Fy) and medio-lateral (Fx) directions were recorded during running.

Results: The results revealed greater medio-lateral ground reaction force at the heel contact in males with pronated feet while running on the ground than that artificial grass. In addition, the time to reach the peak of the vertical component at heel contact during running on grass was greater compared to the ground.

Conclusion: The results showed that the use of artificial turf can improve the risk factors for injury in people with pronated and supinated feet.
