ELİT VE ELİT ALTI CİRİT ATICILARININ ATIŞ TEKNİKLERİNİN 3 BOYUTLU DOĞRUSAL KİNEMATİK ANALİZİ

Öz

Araştırmamızın amacı; elit ve elit altı (elit olmaya aday) düzeydeki cirit atıcılarının atış tekniklerinin, üç boyutlu doğrusal parametrelerinin tespit edilmesidir. 3 boyutlu videografi yönteminin kullanıldığı araştırmamızda 5 elit, 5 elit altı toplam 10 cirit sporcusu alınmıştır. Sporcuların teknikleri 100 hz’lik üç adet kamerayla kaydedilmiş, omuz, dirsek, bilek ve ciritin x, y, z eksenleri üzerindeki doğrusal kinematik analizleri, Simi Motion 6.2 Hareket Analiz programı kullanılarak yapılmıştır. Gruplar arasındaki fark, SPSS 11.5 programında, Mann Whitney U testiyle tespit edilmiştir. Elit ve elit altı atıcıların taşıma evresinde; omuzun x, dirseğin x, y ve z, bileğin x ve y, ciritin de y ekseninde, kuvvet uygulama evresinde; omuz ve dirseğin y, bileğin y ve z, ciritin z ekseninde, atış evresinde ise; omuzun y, dirseğin y ve z, bileğin x, y ve z, ciritin de x ve z eksenindeki doğrusal hızları açısından istatistiksel olarak anlamlı farklılıklar bulunmuştur (p<0.05). Elit sporcular hız alma evresinde aldıkları hızları, kuvvet uygulama ve atış evresine uygun şekilde taşımalarına rağmen elit altı sporcular; kuvvet uygulama evresinde; dirseklerini içeriye fazla çekip, gövdelerini geriye yatırdıkları, atış evresinde de; dirseklerini öne tam çekmeyip aşağı düşürerek ciriti elden çıkarmalarıyla hız alma evresinde aldıkları hızları doğru yönlendirememiş, dolayısıyla yaptıkları teknik hatalar optimal atış mesafesini yakalayamamalarına neden olmuştur

ELITE AND UNDER ELITE JAVELIN THROWERS’ 3 DIMENSIONAL LINEAR KINEMATIC ANALYSIS OF THEIR THROWING TECHNIQUES

Abstract

The aim of this study is to find the elite and under elite (candidate to be elite) javelin throwers’ throwing techniques’ 3 dimensional linear parameters. In our study, 5 elite and 5 sub-elite javelin throwers were used as a athlete with the help of 3dimensional videography method. The techniques of the athletes’ were recorded with 3 cameras with 100hz speed. The linear kinematic analysis on the shoulder, elbow, wrist and the javelin’s x, y, z, axis were made by using Simi Motion 6.2 programme. The differences between groups were fond with Mann Whitney U test on the SPSS 11,5 programme. Significant differences were found statistically among the linear velocity on the delivery phase of the elite and sub-elite throwers; on the shoulder’s x, elbow’s x, y and z, wrist’s x and y, javelin’s y axis; on the accelaration phase; shoulder and elbow’s y, wrist’s y and z, javelin’s z axis; on the throwing phase; shoulder’s y, elbow’s y and z, wrist’s x, y and z, javelin’s x and z axis (p<0,05). Elite athletes have no difficulty on carrying their speed well to the accelaration and throwing speed from the run-up phase, but under elite athletes push their elbows to the inner side and move their body to the back on the accelaration phase; by pulling their elbow to the front exactly and falling their elbows and because of it, falling the javelin from the hand on the throwing phase and they couldn’t divert their speed which was achieved on the run-up phase, so they couldn’t catch the optimal throwing distance because of the making technique mistake
