چکیده
هدف از پژوهش حاضر، مقایسه تأثیر تمرین پلایومتریک قبل و بعد از بلوغ همراه با تمرین فوتبال بر شاخص­ الکترومایوگرافی و عملکرد بازیکنان فوتبال بود. تعداد 30 دانش ­آموز فوتبالیست قبل از بلوغ (وزن 6/59±32/38 کیلوگرم، سن 0/53±10/35 سال و قد 6±141 سانتی‌متر) و بعد از بلوغ (وزن 96/10±79/43 کیلوگرم، سن 0/72±15/43 سال و قد 9±156 سانتی‌متر) از شهرستان دلفان انتخاب شدند. آزمودنی‌ها در دو گروه 15 نفرِ قبل و بعد از بلوغ قرار گرفتند. برای ارزیابی سن از شاخص­هایی همچون قد، سن دندانی و سن استخوانی (روش پرتونگاری) استفاده شد، سپس جهت همگن­کردن گروه­ها از شاخص سن بیولوژیکی توسط رادیولوژیست استفاده شد. قبل و بعد از 4 هفته تمرین، آزمون‌های عملکردی دو 20 متر سرعت، چابکی، پرش سارجنت و همچنین آمپلی­تود عضله پهن جانبی گرفته شد. نتایج با استفاده از آزمون t زوجی نشان داد در گروه قبل از بلوغ در پرش عمودی، چابکی و 20 متر سرعت تفاوت معناداری مشاهده شد. در گروه بعد از بلوغ تنها در عملکرد پرش عمودی و چابکی تغییرات معناداری مشاهده شد و در سایر متغیرها تفاوت معناداری مشاهده نشد. در تغییرات بین گروهی آزمون t مستقل نشان داد، تنها در آزمون 20 متر سرعت تفاوت معناداری مشاهده شد و در سایر متغیرها باوجود تفاوت­های ظاهری، ازنظر آماری تفاوتی نداشت. نتایج پژوهش نشان داد تمرین پلایومتریک در گروه قبل از بلوغ نسبت به گروه بعد از بلوغ اثری بیشتری داشت و این نتایج می­تواند به مربیان گروه­های سنی قبل از بلوغ در استفاده از این نوع تمرینات در طراحی تمرین فوتبال کمک شایانی کند.

چکیده English

The purpose of this study was to compare the effect of plyometric training pre and post maturation period with soccer training on electromyographical index and soccer players performance. 30 students of soccer player's pre maturation period (weight 32.38±6.59 kg, age 10.35±0.59 years, and height 141±0.06cm) and post maturation period (weight 43.79±10.96 kg, age 15.43±0.72 years, and height 156.84±0.09 cm) were selected. Subjects in the experimental group were 15 students before and after maturity period. To evaluate the age of the indices such as height, age, dental and bone age (radiographic method) was used. Then, for homogeneous groups of index of biological age radiography was used by radiologists. Before and after 4 weeks of training,, functional tests of two 20 meter speed, agility, vertical jump and also Amplitude for vastus lateralis muscle Were taken. The result by using Paired t-test showed that in pre maturation group in the vertical jump, agility and 20 meters there was a significant difference (P=0.002,P=0.006,P=0.001) and the other variables there was no significant difference. In variations between the groups, independent t-test showed that only significant differences was found in the test 20 meter speed (P = 0.007) and in the other variables not significantly different. The results showed that plyometric training in the Pre maturation group compared to post maturation group were more effect and these results can help in the design training for premature age groups
