چکیده

مقدمه و اهداف
با توجه به اهمیت تمرینات ثبات مرکزی و همچنین شیوع بالای اسپرین و ناپایداری عملکردی مچ پا و متعاقب آن افزایش نوسان پوسچر بعنوان یک ریسک فاکتور در وقوع اسپرین مجدد مچ پا، انجام تمرینات ثبات مرکزی با هدف ایجاد ثبات در ناحیه مرکزی بدن می­تواند نقش بسزایی در کاهش نوسان پوسچر داشته باشد. لذا هدف از تحقیق حاضر بررسی تاثیر کوتاه مدت تمرینات ثبات مرکزی بر روی نوسان پوسچر ورزشکاران مبتلا به بی­ثباتی عملکردی مچ پا می­باشد.
مواد و روش ها
30 مرد ورزشکار دانشگاهی مبتلا به ناپایداری عملکردی مچ پا در این تحقیق شرکت کردند. پس از غربالگری اولیه و شناسایی ورزشکاران واجد شرایط با استفاده از پرسشنامه ارزیابی عملکرد مفصل مچ پا، آزمودنی­ها به دو گروه تجربی(15 نفر) و گروه کنترل(15 نفر) تقسیم شدند. ورزشکاران گروه تجربی دو نوع از تمرینات ثبات مرکزی را در یک جلسه تمرینی انجام دادند. ارزیابی میزان نوسان پوسچر در هر دو گروه قبل و بعد از آزمون انجام گرفت.
یافته ها
نتایج آزمون آماری نشان داد که تمرینات ثبات مرکزی روی نوسان پوسچر ورزشکاران دارای بی­ثباتی عملکردی مچ پا بصورت کوتاه مدت در حالت چشمان بسته اثر دارد و بطور معنی­داری باعث کاهش نوسان پوسچر می­شود (05/0>P) اما این تمرینات بر روی نوسان پوسچر در حالت چشمان باز اثر معنی­داری نداشت(05/0<P).
نتیجه گیری
بنظر می­رسد که عضلات ثبات دهنده مرکزی در کنترل مفاصل پروکسیمال و دیستال برای کاهش نوسان پوسچر ورزشکاران دارای بی­ثباتی عملکردی مچ پا در حالت چشمان بسته نقش مهمی دارند و انجام این تمرینات در کوتاه مدت می­تواند درکاهش نوسان پوسچر ورزشکاران دارای بی­ثباتی عملکردی اثر مثبت داشته باشد. پیشنهاد می­شود در درمان کاهش نوسان پوسچر ورزشکاران دارای بی­ثباتی عملکردی مچ پا علاوه بر تمرین دادن عضلات ناحیه مچ پا، عضلات ثبات دهنده مرکزی نیز تمرین داده شوند.

چکیده [English]

Background and Aim: Given the importance of core stability exercises as well as the high incidence of ankle sprains and functional instability and Subsequently, increasing of postural sway as a risk factor for the occurrence of ankle sprain, Core stability exercises aimed at stabilizing the central area of ​​the body can have a significant role in reducing postural sway. Therefore the purpose of this study is the immediate effect of core stability exercises on postural sway in athletes with functional ankle instability.
Materials and Methods: Thirty male college athletes with functional ankle instability participated in this study. After Primary screening and identification of eligible athletes with ankle joint functional assessment tool (AJFAT), subjects were divided into the experimental (n=15) and control group (n =15). Athletes’ experimental group did two types of core stability exercises in a session. Postural sway measured in both groups before and after the test.
Results: Statistical test results showed that the core stability exercises affected the postural sway in athletes with functional ankle instability in the short-term with the closed eyes and significantly reduced their postural sway (p˂0/05). But this exercises had no effect on postural sway with open eyes (p<0/05).
Conclusion: It seems that core stabilizer muscles are important in control of proximal and distal joints for reduction of postural sway in athletes with functional ankle instability when their eyes are closed and doing this exercises in the short-term can be useful in reduction of postural sway in athletes with functional ankle instability.
