چکیده

مقدمه و اهداف
هدف از مطالعه حاضر تعیین اثربخشی هشت هفته تمرینات پیش­رونده پرش-فرود و تمرینات چابکی بر عملکرد و تعادل پویای فوتبالیست‌های در معرض خطر آسیب لیگامان صلیبی قدامی بود.
مواد و روش­ ها
30 فوتبالیست مرد در معرض خطر آسیب لیگامان صلیبی قدامی (غربال­شده به وسیله آزمون غربالگری عملکردی) به طور داوطلبانه برای مطالعه حاضر انتخاب شده و به صورت تصادفی به دو گروه تمرینات پیش­رونده پرش-فرود (تعداد= 15 نفر؛ سن 77/0±8/17 سال؛ قد 84/4±2/169 سانتی­متر؛ وزن 86/5±4/63 کیلوگرم) و گروه کنترل (تعداد= 15 نفر؛ سن 84/0±18 سال؛ قد 75/3±2/168 سانتی­متر؛ وزن 71/7±46/64 کیلوگرم) تقسیم­بندی شدند. آزمون­های هاپینگ (آزمون جهش تک­پا، جهش سه­گانه تک­پا، جهش سه­گانه متقاطع تک­پا و مدت زمان جهش تک­پا) و آزمون Y به ترتیب جهت ارزیابی عملکرد و تعادل پویا استفاده شد (در پیش­آزمون و پس از هشت هفته تمرین پیش­رونده پرش-فرود). برای تجزیه و تحلیل اطلاعات از آمون آماری آنوای دو در دو و تی زوجی در برنامه SPSS نسخه 22 استفاده شد.
یافته­ ها
نتایج نشان داد که اجرای هشت هفته پروتکل تمرینی پیش­رونده پرش-فرود، باعث ایجاد تغییرات معنادار در نمرات آزمون­های عملکردی (001/0=P) و تعادل پویا (001/0=P) آزمودنی­ها می­شود.
نتیجه ­گیری
نتایج تحقیق نشان داد اجرای هشت هفته تمرینات پیش­رونده پرش-فرود، منجر به بهبود عملکرد و تعادل پویای آزمودنی­ها می­شود؛ لذا می­توان این نوع تمرینات را جهت بهبود عملکرد و تعادل در فوتبالیست­های جوان در معرض خطر آسیب لیگامان صلیبی قدامی توصیه نمود.

چکیده [English]

Background and Aim: The aim of the present study was to determine the effectiveness of eight weeks of progressive jump-landing exercises on the performance and dynamic balance in young football players prone to anterior cruciate ligament injury.
Materials and Methods: In the current study, 30 football players prone to the risk of anterior cruciate ligament injury (screened by functional movement screening tests) participated on a voluntary basis and were randomly divided into two groups of progressive jump-landing exercises (n=15; age 17.8±0.77 yrs; height 169.2±4.84 cm, weight 63.4±5.86 kg) and control (n=15; age 18±0.84 yrs; height 168.2±3.75 cm, weight 64.46±7.71 kg). The hoping (single leg hop, triple hop, triple diagonal hop, and timed hop) and Y balance tests were used for evaluation of performance and dynamic balance, respectively (at baseline and after 8-weeks of progressive jump-landing exercises). For statistical analysis, the mixed 2*2 analysis of variance and paired t-tests in SPSS, v. 22, were used.
Results: The results revealed that eight weeks of progressive jump-landing exercises led to significant effects on the scores of performance (P=0.001) and dynamic balance (P=0.001) tests in participants.
Conclusion: According to the results, eight weeks of progressive jump-landing exercises could improve participants' performance and dynamic balance, so this type of exercise is recommended for improving performance and dynamic balance of young football players prone to the risk of anterior cruciate ligament injury.
