This study was
conducted to investigate the relationship between isokinetic strength and ball
shoot velocity in elite handball players. Thirteen voluntary male handball players, who were
playing in the handball super league, participated in the study. The isokinetic
shoulder internal (IRPT) and external (ERPT) rotation peak torques (60°s^-1,
240°s^-1 and 400°s^-1) of the handball players’ by
isokinetic dynamotres, their ball shooting velocitys were determined by radar
device. Spearman Correlation Analysis was utilized to determine the
relationship between isokinetic shoulder strength and ball shooting velocity. As a result of the statistical analysis, it has
been found that there is a positive relationship between a IRTP (60°s^-1, 240°s^-1
and 400°s^-1) and the ball shooting velocity while not
moving and IRPT (240°s-1) and the ball shooting velocity while moving. As
a result, significant relationship has been detected between the upper
extremity strength used in handball and ball shooting velocity which has a
direct effect on the individual and team performance of the athletes. In
particular, coaches may be advised to include tranining on the strengthening of
internal rotator muscles (M. Subscapularis, M. Delteiod Aterior, Pectoralis Major
etc.)  affecting ball velocity during
internal rotation.

Elit Hentbol Oyuncularında Omuz İzokinetik Kuvveti ile Top Atış Hızı Arasındaki İlişkinin İncelenmesi

Öz

Bu çalışma elit
hentbol oyuncularında omuz izokinetik kuvveti ile top atış hızı arasındaki
ilişkiyi araştırmak amacıyla yapılmıştır. Çalışmaya hentbol süper liginde
mücadele eden 13 gönüllü erkek hentbolcu katılmıştır. Hentbolcuların izokinetik
omuz internal (IRPT) ve eksternal (ERPT) rotasyon peak torkları (60°s^-1, 240°s^-1 ve 400°s^-1) izokinetik dinamotre ile durarak ve hareketli top
atış hızları ise radar cihazı ile belirlenmiştir. Hentbolcuların izokinetik
omuz kuvveti ile top atış hızı arasındaki ilişkiyi belirlemek için Spearman Korelasyon
Analizi kullanılmıştır. Yapılan istatistiksel analiz sonucunda IRTP (60°s^-1, 240°s^-1 ve 400°s^-1) ile durarak top atış hızı arasında ve IRPT (240°s^-1) ile hareketli şekilde top atış hızı arasında
pozitif yönde anlamlı bir ilişki bulunmuştur. Sonuç olarak hentbolda yoğun olarak kullanılan üst
ekstremite kuvveti ile sporcuların bireysel ve takım performanslarına doğrudan
etkisi olan top atış hızı arasında pozitif doğrultuda anlamlı bir ilişki tespit
edilmiştir. Özellikle antrenörlerin antrenman içerklerinde internal rotasyonda
top atış hızını etkileyen internal rotatör kasların (M. Subscapularis, M.
Delteiod Aterior, Pectoralis Major vb.) kuvvetlendirilmesine yönelik
çalışmalara yer vermeleri önerilebilinir.
