RELATIONSHIP BETWEEN SHOULDER ROTATOR MUSCLE STRENGTH AND UPPER EXTREMITY PERFORMANCE TESTS IN ADOLESCENT TENNIS PLAYERS

Abstract

ADOLESAN TENİS OYUNCULARINDA OMUZ ROTATOR KAS KUVVETİ İLE ÜST EKSTREMİTE PERFORMANS TESTLERİ ARASINDAKİ İLİŞKİ

Öz

Amaç: Tenis oyuncularında omuz performansı ile ilişkili birçok faktör bulunmaktadır. Bu çalışmanın amacı, adolesan tenis oyuncularının üst ekstremite performans parametreleri ile omuz rotator kas kuvveti arasındaki ilişkiyi incelemekti.
Yöntem: Çalışmaya 10 ile 18 yaş arası 31 adolesan tenis oyuncusu dahil edildi. Üst ekstremite performansını belirlemede sağlık topu fırlatma, kapalı kinetik zincir üst ekstremite stabilite testi ve kavrama kuvveti testi kullanıldı. Omuz rotator izokinetik kas kuvveti ISOMED 2000 (D&R GmbH, Almanya) sistemi ile değerlendirildi. İstatistiksel analizde doğrusal regresyon analizi kullanıldı.
Sonuçlar: Sağlık topu fırlatma mesafesi ile 60°/s açısal hızda internal rotator (İR) tepe tork (TT) (r=0,535, p=0,002) ve eksternal rotator (ER) TT (r=0,421, p=0,018) değerleri arasında pozitif yönde orta düzeyde ilişki bulundu. Kavrama kuvveti ile 60°/s İR-TT (r=0,647, p=0,001) ve ER-TT (r=0,645, p=0,001) değerleri arasında güçlü düzeyde ilişki bulundu. Kapalı kinetik zincir üst ekstremite stabilite test sonuçları ile 60°/s ER TT arasında ilişki saptandı (r=0,391, p=0,029).
Tartışma: Çalışmanın sonucunda; adolesan tenis oyuncularında omuz rotator kas kuvveti artıkça omuz performansının arttığı görüldü. Tenis oyuncularında performansı etkileyen faktörlerin adolesan dönemde saptanması, performansı arttırmak ve koruyucu yönde önlemler almak için oldukça önemlidir.
