چکیده

مقدمه و اهداف
اثرات بیومکانیکی کفی طبی بر بهینه کردن الگوی حرکتی به ویژه در اندام تحتانی در علوم توانبخشی مستند شده است؛ اما نتایج کاربرد آن در تغییرات الگوهای حرکات پایه‌ای ورزشی به خوبی شناخته نشده است. هدف مطالعه ی حاضر، بررسی اثر فوری سه نوع کفی طبی سخت، نیمه‌سخت و نرم بر نسبت فعالیت عضلات پهن داخلی مایل به پهن خارجی بود.
مواد و روش‌ها
در مطالعه نیمه تجربی حاضر تعداد 13 مرد شرکت کردند. فعالیت الکترومیوگرافی عضلات پهن داخلی مایل به پهن خارجی حین انجام تکلیف فرود-پرش تک‌پا در وضعیت های: پوشش کفش بدون کفی، کفی نرم، نیمه سخت و کفی طبی سخت ثبت و نسبت VMO/VL مقایسه شد. از آزمون آنالیز واریانس با اندازه‌های تکراری برای تجزیه و تحلیل داده ها استفاده شد (05/0< P).
یافته‌ها
میزان فعالیت عضله ی پهن داخلی مایل در مرحله انقباض اکسنتریک در انجام تکلیف فرود- پرش با کفی نرم به طور معناداری بیشتر از کفی نیمه‌سخت بود. میزان فعالیت عضله ی پهن خارجی نیز در مرحله اکسنتریک در کفی نرم به طور معناداری بیشتر از حالات بدون کفی و کفی سخت بود. در مراحل پیش‌فعالیت و کانسنتریک تفاوت معناداری در فعالیت عضلات پهن داخلی مایل و پهن خارجی میان وضعیت-های مختلف مشاهده نشد. نهایتاً، نسبت VMO/VL در مرحله ی اکسنتریک در کفی سخت به طور معناداری بیشتر از کفی نیمه‌سخت بود.
بحث و نتیجه‌گیری
کفی طبی سخت می‌تواند نسبت VMO/VL را حین اجرای تکلیف فرود-پرش افزایش دهد. به نظر می رسد که استفاده از کفی سخت به بهبود و تسریع توانبخشی افراد با مشکلات عدم تعادل بین عضلات پهن داخلی مایل و پهن خارجی در اجرای حرکات پرشی مفید باشد.

چکیده [English]

Background and Aim: Although the biomechanical effects of insole on optimization of movement patterns, especially in the lower limbs in rehabilitation sciences, have been documented, the effect of applying it in modifying sports basic movement patterns is not well-known. The aim of present study was to investigate the effect of three foot insoles (rigid, semi-rigid, and soft) on electromyography activity ratio of VMO and VL muscles.
Materials and Methods: A total of 13 male participants took part in the present semi-experimental study. Electromyography activities of Vastus Medialis Obliqe (VMO) and Vastus Lateralis (VL) muscles were recorded and VMO/VL ratio was compared in four conditions: wearing only shoes, soft-sole, semi-sole, and rigid-sole during one-leg drop jump. ANOVA with Repeated measures test was used for data analyses (p<0.05).
Results: The VMO muscle activation in soft-sole condition significantly increased in comparison with semi-rigid condition in the eccentric phase (P<0.05). There was a significant increase in electromyography activation for Vastus lateralis muscle in soft-sole condition compared to non-sole and rigid-sole in the eccentric phase (P<0.05). Also, there was no significant difference observed for VMO and VL activation in conditions during concentric and pre-activation phases. Finally, VMO/VL activation ratio in rigid-sole significantly increased in comparison with semi-sole in the eccentric phase.
Conclusion: Considering the influence of rigid insole on increasing the VMO/VL ratio during the execution of drop jump task, it seems that using rigid insole may be useful in improving and expediting individuals' rehabilitation with imbalance problems between VMO and VL muscles during jumping tasks.
