چکیده
کودکی دورة مهمی برای مداخله درراستای پیشگیری از آسیب ورزشی است. یکی از تمرین‌های پیشنهادی، تمرین ثبات مرکزی است؛ براین‌اساس، هدف پژوهش حاضر، ارزیابی تأثیر شش هفته تمرین ثبات مرکزی بر بیومکانیک پرش- فرود تک‌پا در کودکان فعال 10 تا 12 سال بود. برای انجام پژوهش، 27 کودک فعال نابالغ 10 تا 12 سال که عضو باشگاه‌های شهر تهران بودند، به دو گروه تجربی و کنترل تقسیم شدند. نتایج نشان داد که متغیرهای کینتیکی شامل نرخ بار و حداکثر نیروی عمودی عکس‌العمل زمین در بازیکنان گروه مداخله تغییری معنادار داشتند؛ اما در زاویة مچ پا در صفحة ساجیتال و فرونتال تغییری معنادار مشاهده نشد. با توجه به نتایج پژوهش، به‌نظر می‌رسد که تمرین‌های ثبات مرکزی تأثیر مثبتی بر برخی از عوامل خطرزای بیومکانیکی پرش- فرود کودکان نابالغ دارند و می‌توانند در پیشگیری از آسیب‌های این ورزشکاران مؤثر باشند.

چکیده English

The childhood is an important period for implementing intervention in order to prevent sport injury. Core stability training is one of them. Therefore, the purpose of this study was to evaluate the effect of 6 weeks of core stability training on biomechanics of single - leg jump-landing task in active children between 10 to 12 years. 27 children were divided into experimental and control groups. Kinematic and kinetic variables, including ankle angles in sagittal and frontal planes, loading rates, and the maximum vertical ground reaction force, were measured using the motion analysis and force plate. The results show that kinetic variables in the experimental group have a significant change, but no significant change was observed in the ankle kinematics. Regarding the results, it seems that core stability exercises have a positive effect on some of the biomechanical risk factors of jump-landing of immature children.
