چکیده
اغلب آسیبهای ورزشی در زمان خستگی رخ میدهند. هدف از پژوهش حاضر بررسی اثر خستگی بر فعالیت الکتریکی عضلات اندام تحتانی در افراد مبتلا به زانوی پرانتزی طی دویدن با کفش چابکی است. در این مطالعۀ نیمهتجربی 14 نفر مرد مبتلا به زانوی پرانتزی و 15 فرد سالم در دامنۀ سنی 20 تا 30 سال شرکت کردند. برای ثبت فعالیت الکتریکی عضلات از سیستم الکترومایوگرافی بایومتریک استفاده شد. نتایج نشان داد فعالیت عضلۀ سرینی میانی در گروه سالم از با گروه پای پرانتزی بزرگتر است. اثر عامل خستگی بر فعالیت عضلۀ درشتنی قدامی طی فاز پاسخ بارگذاری از لحاظ آماری معنادار بود. بهطور کلی، با توجه به عملکرد متفاوت دو عضلۀ درشتنی قدامی و نیموتری طی دویدن قبل و بعد از خستگی، در افراد مبتلا به زانوی پرانتری، در مقایسه با افراد سالم، توانبخشی این دو عضله در افراد مبتلا به زانوی پرانتزی ضروری است

Most sports injuries occur during fatigue. The aim of the present study was to evaluate the effect of fatigue protocol on lower limb muscular activities in individuals with genu varus during running with agility shoes. In this study, 14 individuals with genu varus and 15 healthy control ones aged 20-30 years volunteered to participate. Muscle activities were recorded using a Biometric system. Findings demonstrated greater gluteus medius activity in the healthy group compared to the genu varus group. The main effect of fatigue on tibialis anterior activity during the loading phase and mid-stance phase was significant. Overall, because of different tibialis anterior and semitendinosus performance in the genu varus group compared with the healthy group during running before and after fatigue protocol, rehabilitation of these muscles is essential in genu varus individuals.
