چکیده

هدف پژوهش حاضر، بررسی اثر خستگی عملکردی عضلات مرکزی بدن بر برخی از متغیرهای کینماتیکی مؤثر بر آسیب لیگامان صلیبی قدامی( ACL)طی مانور برش بود. تعدادی از ورزشکاران دانشگاهی شامل 24 نفر در دو گروه تجربی (13 نفر) و کنترل (11 نفر) در پژوهش حاضر شرکت کردند. حرکت برش با استفاده از سیستم تحلیل حرکت و دوربین‌های پرسرعت وایکان، با فرکانس 240 هرتز ثبت شد و حرکات ثبت‌شده به‌وسیلۀ نرم‌افزار نکسوس آنالیز شدند و زوایای مفصلی نمونه­ها (فلکشن زانو، والگوس زانو، نسبت چرخش تیبیا به فمور در لحظة برخورد پا با زمین و میزان حداکثر میزان فلکشن زانو، والگوس زانو و همچنین، نسبت چرخش تیبیا به فمور در 50 درصد اولیة فاز سکون) استخراج شد و توسط آزمون آماری تی وابسته و تحلیل کوواریانس تک‌متغیره مقایسه شد. نتایج نشان داد که خستگی عضلات مرکزی بدن بر خطر آسیب ACL درطول مانور برش مؤثر است.

چکیده [English]

The aim of this study was to investigate the effect of core muscles functional fatigue on some of kinematics parameters related to ACL injury during cutting maneuver. A number of college student athletes' soccer athletes, including 24 persons in two experimental (n=13) and control (n=11) groups participated in the study. Cutting maneuvers were recorded by motion analysis system using six Vicon high-speed cameras, with a frequency of 240Hz. Movements were analyzed by Nexus software and joint angles (knee flexion, knee valgus and tibia rotation with respect to femur at the moment of heel contact and the maximum amount of knee flexion, knee valgus and tibia rotation with respect to femur at the first 50% stance phase) were collected. SPSS and paired T-Test and ANCOVA were used to comparing two groups. The results indicated that core muscles functional fatigue was affected on ACL injury risk factors during cutting maneuver.
