چکیده
هدف از پژوهش حاضر تعیین تاثیر تمرین پلایومتریک بالاتنه بر توان بی‌هوازی بالاتنه و مراحل مختلف عملکرد شنای 25 متر کرال سینه شناگران پسر 10 ساله بود. بدین منظور 16 نفر از شناگر (میانگین سن7/0±9/9 سال، وزن 9±9/45 کیلوگرم، قد 5 ±8/149سانتی‌متر، شاخص توده بدن 3±19/20 کیلوگرم بر مترمربع) به صورت داوطلبانه انتخاب شدند. آزمودنی‌ها به یک گروه تمرین پلایومتریک (8 نفر) و کنترل (8 نفر)تقسیم شدند. پیش و پس از اجرای پروتکل، آزمون رکورد 25 متر شنا کرال سینه در مسافت های10، 20 و 25 متر و تعداد ضربات دست جهت بررسی عملکرد شنا و تست وینگیت دست جهت بررسی عملکرد توان بی هوازی انجام شد. بررسی داده‌ها، از طریق تحلیل کوواریانس صورت پذیرفت. نشان داد، شش هفته تمرین ‏پلایومتریک بالاتنه روی دست شناگران کرال سینه شاخص‌های عملکردی از جمله اوج توان به میزان 18 درصد نسبت به گروه کنترل پیشرفت معنی‌داری داشت اما میانگین توان با اینکه 7 درصد پیشرفت داشت اما معنا دار نبود(05/0<p). همچنین عملکرد ‏شنا در مسافت های10متر (8 درصد)، 10 الی 20 متر (6 درصد) و در مسافت 25 متر (80/3 درصد) پیشرفت نسبت به گروه کنترل وجود داشت که معنی داری در همه مسافت ها مشاهده شد (05/0> p) همچنین در تعداد ضربات دست شنا گروه تمرین پلایومتریک با اینکه در مسافت‌های 10 متر شنا (11 درصد)، در مسافت 10 الی 20 متر (5/7 درصد) و در مسافت 25 متر (33/5 درصد) پیشرفت داشته ‌اند ولی این تغییرات معنی دار نبود. (05/0<p). نتایج نشان داد شش ‏هفته تمرین پلایومتریک بالاتنه در افزایش و بهبود پارامترهای اندازه گیری شده موثراست و می تواند به عنوان یک روش تمرینی مکمل در شناگران جوان مورد استفاده قرار گیرد.

چکیده English

The purpose of this study was determine the effect of upper body plyometric training on anaerobic power and record of 25 meters front crawl performance in 10 years old swimmer boys. 16 swimmer boys chosen voluntarily (The mean age was 9.9 ± 0.7 years ، weight 45.9 ±9 kg , Height 149.8 ± 5 cm، BMI is 19.20 ± 3 Kg / m 2 ) And Subjects divided into two groups of training (n=8) and control(n=8).Before and after the implementation of the protocol investigate test 25 meters front crawl performance at the distance 10, 20 and 25 metrs and the number of hand strocke to check the performance of the swimming also anaerobic hand wingiting test function was evaluated. To analyze data, used the covariance test.The results showed six weeks upper body plyometric training Performance Indicators an hands Front crawl Including Peak power increased Significantly (18%) but the average power increase (7%) was not significant (p>0.05). Also, Swimming performance at of 10 meters) 8% (,10 to 20)6%( and 25 meters distance( 3/80%) growth in compare to control group that was significant(p <0.05) As well as in the number of hand strocke, Plyometric training group although had growth in swim 10 meters (11%), 10-20 meters (7.5%) and in 25 meters distance (5.33%) but the isnt significance (p>0.05). results indicate that six week upper body plyometric traning to an increase and improvement in the measured parameters, and can be used as a complementary training method in young swimmers.
