Abstract

Lower leg strength and upper extremity strength are important for maximizing performance in athletics. In sports performance studies, it has been reported that force imbalances between the core region and lower extremities will cause muscle injuries. From this point of view, isokinetic leg forces and trunk core forces are investigated in throwing (javelin and discus) and jumping (long jump) events in athletics. In the Mersin region, the licensed age was 17.50 ± 2.57; discus throwers (n = 6), javelin throwers (n = 6) and long jumpers (n = 6), including; Isokinetic leg strength of 18 athletes (9 males, 9 females) at 60°s; core strength; Isokinetic Dynamometer and trunk dynamometer (Cybex Humac Norm Testing and Rehabilitation System, USA) at 120° / 60° sec angular velocities, body compositions (height: 173.33 ± 9.87; weight: 70.51 ± 14.76; BMI: 23,13 ± 3,17) and Tanita BC-418 segmental body analysis scale. Trunk 1200 and 600 Ex (r = .921, r = .917 p <0.01) did not show any relationship between jumping throwers and jumps (p <0.01). It is thought that the presence of a circular motion in the biomechanics of the discus thrower and the activation of the centrifugal force can cause a positive relationship between the leg strength and the transferring core strength, but this relationship could not be detected in the javelin throwing and long jump.

Özet

Atletizmde alt bacak kuvveti ve üst ekstremite kuvveti performansın maksime edilebilmesi için önemlidir. Sportif performans araştırmalarında kor bölgesi ile alt ekstremite arasındaki kuvvet dengesizliklerinin kas yaralanmalarına neden olacağı bildirilmiştir. Buradan hareketle, atletizm atmalar (cirit ve disk) ve atlamalar (uzun atlama) branşında izokinetik bacak kuvvetleri ile gövde (trunk) kor bölge kuvvetleri incelenerek yaptıkları branşa özgü her hangi bir ilişki olup olmadığı araştırılmıştır. Mersin bölgesinde atletizmde lisanslı yaşları 17,5 ± 2.57 olan; disk atma (n=6), cirit atma (n=6) ve uzun atlama (n=6), branşlarından olmak üzere; 9 erkek, 9 kadın toplam 18 sporcunun izokinetik bacak kuvveti 60°sn hızlarda; gövde (core) kuvveti; İzokinetik Dinamometre ve Trunk dinamometre ile (Cybex Humac Norm Testing & Rehabilitation System, USA) 120°/60°sn açısal hızlarda, vücut kompozisyonları (boy:173.33±9,87; kilo:70,51±14,76; VKİ: 23,13± 3,17) ise TANITA BC-418MA segmentel vücut analiz tartısı ile ölçülmüştür. Disk atan bireylerde sağ sol bacak kuvvetleri ile trunk 1200 ve 600 Ex (r=.921, r=.917 p<0,01) kuvvetleri arasında ilişki varken, cirit atanlarda ve atlama branşındaki sporcularda her hangi bir ilişki bulunamamıştır (p<0,01). Disk atma branşının biyomekaniğinde bir dairesel hareketin olması ve merkez kaç kuvvetinin de devreye girmesi ile bacak kuvveti ve bunu üste aktaran kor kuvvetin pozitif ilişkiye sebep olabileceği düşünülürken düzgün doğrusal hareketleri içeren cirit atma ve atlama branşlarında bu ilişki saptanamamıştır.
