چکیده
با توجه به اینکه اسکات یک حرکت رایج در تقویت عضلات اندام تحتانی به‌منظور پیشگیری از آسیب‌ها است، مطالعه حاضر باهدف مقایسه فعالیت الکترومیوگرافی عضلات پهن داخلی و خارجی در سه شیوه حرکت اسکات فوتبالیست­های مرد طراحی و اجرا گردید. 15 فوتبالیست مرد 18 تا 25 سال باسابقه بیش از دو سال تمرین منظم تکنیک­های اسکات پا جمع، پا باز و لانچ را هم‌زمان با ثبت فعالیت الکترومیوگرافی عضلات پهن داخلی و پهن خارجی انجام دادند. داده­ها با آزمون­های آماری تی وابسته و مستقل و تحلیل واریانس اندازه­های تکراری تحلیل شدند. فعالیت الکترومایوگرافی دو عضله پهن داخلی و خارجی در مرحله بالا آمدن، پایین رفتن و با تغییر نوع اسکات تفاوت معناداری نشان نداد. عضله پهن خارجی در تمام حالات اسکات فعالیت بیشتری نسبت به عضله پهن داخلی نشان داد. اگرچه پیشنهادشده است عضله پهن داخلی در کنترل حرکت اسکات فعالیت بیشتری دارد؛ اما تناقض آن با یافته­های این مطالعه می­تواند به دلیل کاهش زاویه Q و واروس زانوی شرکت‌کنندگان باشد.

چکیده English

As Squat is a popular exercise for support of lower extremity muscles in order to injury prevention this study has been hold to comprise the electromyography of vastus medialis and vastus lateralis muscles in three Squat techniques of man soccer players. 15 soccer players, aged 18-25 years old, who had regular exercise more than two years did open, closed and lung Squats exercise while electromyography of vastus medialis and vastus lateralis muscles were recorded. Data analyzed by using dependent and independent T test and repeated measure ANOVA. There was not significant difference of vastus medialis and vastus lateralis muscles’ electromyography during getting up, going down phases and also for different squat techniques. The vastus lateralis muscle show more activity in all conditions. Though, it is recommended that vastus medialis has bold role for controlling of squat exercise, reduction of Q angle and participants’ knee varus in this study can be the reason of antithesis.
