چکیده
آگاهی از ارتباط بین عملکردها و دامنه حرکتی، کمکی برای طراحی برنامه تمرینی، منطبق با نیازهای فردی کودکان به شمار می‌رود، ازاین‌رو، تحقیق حاضر باهدف تعیین ارتباط بین برخی پارامترهای دامنه حرکتی اندام تحتانی و بیومکانیکی پسران انجام شد. صد دانش‌آموز پسر، در این تحقیق به‌صورت تصادفی انتخاب شدند. بعد از اندازه‌گیری دامنه حرکتی اندام تحتانی، آزمون‌های سرعت، توان، تعادل و چابکی آزمودنی‌ها ثبت شد. از آمار توصیفی برای تعیین میانگین و انحراف استاندارد، از روش همبستگی پیرسون چندگانه برای ارزیابی ارتباط بین منتخبی از پارامترهای دامنه حرکتی و بیومکانیکی آزمودنی‌ها، استفاده شد. فلکشن ران با سرعت، آبداکشن ران و فلکشن زانو با تعادل، فلکشن و هایپرآداکشن ران و دورسی فلکشن مچ پا با چابکی ارتباط مثبت و معنادار، میزان فلکشن ران و زانو ارتباط منفی و معنادار و بقیه پارامترها ارتباط مثبت و معناداری با توان را نشان دادند. با توجه به یافته‌های تحقیق، به نظر می‌رسد بتوان از ویژگی‌های دامنه حرکتی اندام تحتانی کودکان و شناسایی شاخصه‌ای عملکردی رشته‌های ورزشی مختلف، استفاده کرد.

چکیده English

Knowledge of the relationship between performance and range of motion, helping to design training programs, comply of individual with the needs of children is, therefore, The aim of research the relationship between some of the lower extremity range of motion and biomechanical parameters of the boys was performed. Hundred students in this study were randomly selected. After measuring the range of motion of lower extremity, test speed, power, balance and agility of the subjects were recorded. By descriptive statistics to determine the mean and standard deviation of the method of multiple correlations to assess the relationship between the selected range of motion and biomechanical parameters of subjects were used. Hip flexion by speed, hip abduction and knee flexion by balance and hip flexion, hyper adduction and ankle dorsi flexion significant positive correlation by the agility, the rate of hip and knee flexion by power a significant negative correlation and with other lower extremity range motion parameters showed a significant positive association. According to the research findings, seem to be characteristics of the children lower extremity range of motion and identify performance indicators for various athletic field, can be used.
