چکیده

موقعیت زوایای زانو در فرود، از عوامل آسیب بازیکنان هندبال است و تمرینات پیشگیرانه می‌تواند میزان آسیب را در این ورزش کاهش دهد. از‌این‌رو، هدف پژوهش حاضر بررسی تأثیر یک برنامۀ تمرینی عصبی‌عضلانی بر سینماتیک اندام تحتانی و عملکرد زانوی بازیکنان مرد هندبال در فرود با یک ‌پا است. 40 بازیکن لیگ برتر سال 1391 از دو باشگاه در دو گروه 20 نفره به‌ترتیب با میانگینقد 5/5±7/187 و 4/6±3/185 سانتی‌متر، وزن 1/10±0/89 و 6/13±8/86 کیلوگرم، سن 6/13±4/25 و 8/3±2/24 سال و سابقۀ بازی 4/4±6/11 و 3/3±8/10 سال انتخاب شدند. تجزیه و تحلیل یافته‌ها در کاهش زوایای والگوس و چرخش داخلی زانو و همچنین افزایش عملکرد اندام تحتانی، تفاوت معنا­داری بین دو گروه نشان دادند. ضمن ‌این‌که در زاویۀ فلکشن زانوی بازیکنان هر دو گروه، هیچ اختلاف معنا­داری مشاهده نشد. به‌طور‌کلی، تمرینات عصبی‌عضلانی می‌تواند موجب بهبود عملکرد اندام تحتانی و کاهش زوایای چرخش داخلی و والگوس زانو در فرود با یک‌ پا شود و نیز می‌تواند به بازیکنان نخبۀ مرد هندبال در پیشگیری از آسیب‌های لیگامنتی زانو، به‌ویژه پارگی رباط‌های صلیبی قدامی در‌طول فصل مسابقات کمک کند.

چکیده [English]

The knee positions could be parameters for injury of handball players in landing. Preventive exercise programs may decrease the injury of players. The aim of this study was to investigate the effect of a Neuromuscular Exercise Program on lower limb kinematics and single leg stability in male handball players. 40 handball players (Regular Training: n=20, height 187.7±5.5 cm; weight 89.0±10.1 kg; age 25.4±13.6 years; handball experience 11.6±6.4 years and neuromuscular training: n=20, height 185.3 ±6.4 cm; weight 86.8±13.6 kg; age 24.2±3.8 years; handball experience 10.8±3.3 years) were selected from two clubs participating in Iran Super League on 2012-2013. There were significant differences between the two groups in inward rotation of femur, knee valgus angles and single leg stability. No significant difference was found in knee flexion angle. Neuromuscular training can improve overall performance and reduce lower extremity valgus angle and internal rotation of the knee during landing with one leg. It may help handball players to prevent knee ligaments injuries, especially ACL, during competition season.
