The Investigation of the Relationship Between Shoulder Izokinetic Strength and Ball Shoot Velocity in Elite Handball Players

Öz

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.
