نویسندگان

چکیده
هدف مطالعه حاضر تعیین تاثیر حاد تمرین پلایومتریک به همراه تغییر ارتفاع فرود برفعالیت الکترومایوگرافی مرحله پیش­آماده­سازی درحرکت فرود-پرش بود. 10 دانشجوی تربیت‌بدنی و علوم ورزشی (سن1/286±21/10سال ، قد6/467±173سانتی‌متر، وزن 7/42±68/2کیلوگرم) در این تحقیق شرکت کردند. آزمودنی‌ها در چهار روز متفاوت یکی از پروتکل­‌های تمرین پلایومتریک و حرکت فرود-پرش از ارتفاع 40 و 60 سانتی‌متر را تک‌پا انجام دادند. فعالیت الکترومایوگرافی مرحله پیش­آماده­سازی گروه عضلانی چهارسر و همسترینگ 150 میلی ثانیه پیش از تماس پا با زمین ثبت شد. از روش آماری تحلیل واریانس با اندازه­‌گیری تکراری و آزمون تعقیبی بونفرونی استفاده شد. نتایج نشان داد فعالیت عضلات راست رانی، پهن خارجی و دو سر رانی در مرحله پیش­‌آماده‌­سازی پس از تغییر ارتفاع فرود افزایش معنی­‌داری به ترتیب ( 0/002=p=0/001 ،p=0/001،p ) داشته است. فعالیت عضلات (راست رانی، پهن خارجی، دو سر رانی) پس از اجرای پلایومتریک و تغییر ارتفاع فرود در مرحله پیش­‌آماده‌سازی افزایش معنی­‌داری به ترتیب (0/039=p، 0/001=p) (0/006=p، 0/000=p) (0/001=p، 0/014=p) داشته است. نتایج این مطالعه نشان داد اجرای تمرین پلایومتریک به شکل حاد با تغییر در ارتفاع فرود موجب افزایش در فعالیت الکتریکی عضلات در فاز پیش­‌آماده­‌سازی و در نهایت افزایش در میزان ارتفاع پرش می­‌شود.

چکیده English

The purpose of this research was to determine the acute effects of plyometric training with changing of height landing on the electromyographic activity during preparatory phase land-jump in male students. The population of this research were 10 physical education male students of Kharazmi University, which selected as sample. (21/10±1/286yrs, 173±6/467 height, 68/2±7/42 weight). In four different days subjects Performed as single leg one of four protocols plyometric training and land - jump from a height of 40 and 60 cm. EMG activity of the quadriceps and hamstring muscle group 150 milliseconds before foot contact with the ground was recorded. Analysis of variance with repeated measures and Bonferroni post hoc test was used. The results of this study showed that muscle activity after changing of height landing in preparatory phase (from 40 to 60 cm) has increased significantly (P=0/002, P=0/001, P=0/001) respectively. Activity of muscles (rectus femoris, vastus lateralis, biceps femoris) during landing after performing plyometric and changing of height landing in preparatory phase has increased significantly (P=0/039, P=0/001) (P=0/006, P=0/000) (P=0/001, P=0/014) respectively. Jump height has increased significantly (P=0/007, P=0/002) respectively. The results showed that acute perform plyometric training with changing of height landing result in significant changes in the electrical activity of muscles and also the height of the jump in the preparatory phase.
