چکیده
مطالعات پیشین نقش تمرینات ثبات مرکزی را بر ارتقای عملکرد ورزشکاران نشان داده‌اند؛ اما مطالعات اندکی به بررسی تأثیر تمرینات ثبات مرکزی بر متغیرهای بیومکانیکی پرداخته‌اند. هدف پژوهش حاضر، بررسی تأثیر هشت هفته تمرین ثبات مرکزی بر نیروی عکس‌العمل زمین، هنگام فرود ورزشکاران مرد پارکور بود. در این مطالعة نیمه‌تجربی، 30 مرد ورزشکار پارکور به‌صورت تصادفی انتخاب شدند و به‌طور تصادفی به دو گروه تجربی (میانگین سن:46/2±07/21 سال، قد: 35/5±10/175 سانتی‌متر، وزن: 27/9±33/67 کیلوگرم) و کنترل (میانگین سن: 31/2±20/20سال، قد: 65/4±93/175، وزن: 45/8±33/67) تقسیم شدند. آزمودنی‌های گروه تجربی به‌مدت هشت هفته و هر هفته، سه جلسه تمرینات ثبات مرکزی را انجام دادند. قبل و بعد از انجام هشت هفته تمرین ثبات مرکزی، متغیرهای نیروی عکس‌العمل زمین و تغییرات مرکز فشار با استفاده از دستگاه صفحه‌نیرو ارزیابی شدند. تجزیه‌وتحلیل داده‌ها با استفاده از آزمون آماری تحلیل کوواریانس در سطح معناداری 05/0 انجام شد. نتایج نشان داد که اختلاف معناداری بین میانگین تغییرات مرکز فشار در هر دو جهت داخلی- خارجی و قدامی- خلفی و نیروی عمودی عکس‌العمل زمین در دو گروه تجربی و کنترل وجود دارد. با توجه به نتایج پژوهش به‌نظر می‌رسد که تمرینات ثبات مرکزی تأثیر مثبتی بر پارامترهای فرود ورزشکاران رشتة پارکور دارند و می‌توانند در پیشگیری از آسیب‌های این ورزشکاران مؤثر باشند.

چکیده [English]
The aim of this study was to evaluate the effect of eight weeks core stability training on center of pressure changes and ground reaction force during landing among male parkour athletes. thirty male were participated in this study. participants were randomized in the experimental group (age=21.07±2.46 years, height= 175.10±5.35 cm, weight= 67.33±9.27 kg) and control group (age=20.20±2.31 years, height= 175.93±4.65 cm, weight= 67.33±8.45 kg) in this semi-experimental study. Experimental group applied eight weeks core stability training. These exercises performed three time per week while the control group performed their routine training. The variables including center of pressure changes and ground reaction force were measured before and after eight weeks core stability training by force plate. Analysis of covariance was used in the 0/05 significant level. The results showed that there was significant difference between experimental and control groups in the mean scores of center of pressure changes in medial- lateral and anterior-posterior direction and ground reaction force. According to results, seems core stability training has positive effect on landing parameter among male parkour athletes and these exercise can prevent sport injuries of them.
