چکیده

مقدمه و هدف: تحقیقات اندکی ارتباط بین نمرات غربال­گری حرکتی عملکردی و فاکتورهای آمادگی جسمانی را در تکواندو مورد بررسی قرار داده­اند. هدف از تحقیق حاضر بررسی ارتباط نمرات غربال­گری حرکتی عمکلردی و فاکتورهای منتخب آمادگی جسمانی پسران تکواندوکار نوجوان بود.
روش شناسی: تحقیق حاضر از نوع تحقیقات توصیفی همبستگی است. جامعه آماری تحقیق پسران نوجوان تکواندوکار شهر همدان بود . 60 ورزشکار (میانگین سنی 41/892/13 سال، جرم 24/8913/45 کیلوگرم، قد 35/3214/156 سانتی­متر) با روش نمونه گیری تصادفی  به­عنوان آزمودنی انتخاب شدند.  آزمودنی­ها بوسیله آزمون­های غربال­گری حرکتی عملکردی  و آزمون­های آمادگی جسمانی مورد ارزیابی قرار گرفتند. نرمال بودن داده­ها با استفاده از آزمون کلموگراف اسمیرنف بررسی شد. داده­ها با استفاده از آزمون­های رگرسیون خطی چند متغیره و همبستگی اسپیرمن تجزیه و تحلیل شدند ( 05/0P≤).
نتایج: مدل نهایی رگرسیون نشان داد آزمون­های نشستن و رسیدن (001/0 p=) و اسکات تک پا (027/0 p=) توانستند به طور معنی­داری نمرات ترکیبی غربال­گری حرکتی عملکردی را پیش­بینی کنند (32/0  R Square=، 003/0 p=، 85/3 F=) . ارتباط معنی­داری بین زمان دو سرعت 20 متر (069/0 p=)، پرتاب توپ مدیسین به عقب (447/0 p=)، پرش عمودی جفت پا (094/0 p=)  و چابکی  (502/0 p=) با نمرات ترکیبی ترکیبی غربال­گری حرکتی عملکردی مشاهده نشد ( 05/0P≤).
نتیجه­گیری: بر اساس مدل رگرسیون، از بین فاکتورهای آمادگی جسمانی، انعطاف­پذیری و استقامت اندام تحتانی با نمرات ترکیبی آزمون­های غربال­گری حرکتی عملکردی ارتباط معنی­دار داشتند. علت احتمالی این ارتباط را می­توان به آزمون­های لانچ خطی، گام برداشتن از روی مانع و بالا آوردن فعال پاها بصورت مستقیم که به انعطاف پذیری نیاز دارند، نسبت داد. از این­رو جهت بهبود نمرات غربال­گری حرکتی عملکردی تکواندوکاران توصیه می­شود انعطاف پذیری و استقامت اندام تحتانی در برنامه تمرینی آنها گنجانده شود.

چکیده [English]

Background and purpose: There is a little research about relationship between the Functional Movement Screen (FMS) and physical fitness factors in taekwondo. The aim of this study was to investigate the relationships between the functional movement screen scores and selected physical fitness factors in the adolescent taekwondo athletes.
Methodology: This study is a descriptive-correlational research. The statistical population of the research was adolescent taekwondo athletes in the Hamadan city. Sixty athletes (age = 13.89 ± 2.41 years; height = 156.32 ± 14.35 cm; body mass = 45.89 ± 13.24 kilograms) were randomly selected as the subject. The subjects were assessed by functional movement screening and physical fitness tests. The normality of data was tested by the Kolmogorov–Smirnov test. Spearman’s correlation and linear multiple regression tests were used for data analysis (p ≤ 0.05).
Result: The final regression model indicated that sit-and-reach (p=0.001) and single leg squat tests (p=0.027) would significantly predict functional movement screen composite scores (F = 3.85, p= 0.003, R Square=0.32). No significant correlation observed between the composite functional movement screen scores and 20-m sprint time (p=0.069), backward medicine ball throws (p=0.447), bilateral vertical jump (p=0.094) and agility (p=0.502).
Conclusion: Among the physical fitness factors, flexibility and lower extremity endurance had significant relationship with composite functional movement screen scores, based on regression model. The probable cause of this relationship can be attributed inline lunge, active straight leg raises and hurdle step tests which require flexibility. Therefore, in order to improve the functional movement screen scores of the taekwondo athletes, it is recommended that the flexibility and endurance of the lower extremity be included in their training program.
