Abstract

Sporculara yapılacak testler sırasında zamansal sınırlılıklar ortaya çıkmaktadır. Farklı yöntemlerin birbirleri yerine güvenle uygulanma durumu bilinmemektedir. Bu çalışmanın amacı, kadın voleybolcularda Q açısının sıçrama ve iniş mekaniği ile ilişkisini incelemektir. Araştırma grubunu İstanbul ve Kocaeli ilinde alt yapı düzeyinde oynayan 48 genç kadın sporcu oluşturmuştur. Araştırmaya katılan kadın voleybol sporcularına antropometrik ölçümler, Q açısı, İniş Hatası Puanlama Sistemi(LESS), Dikey Sıçrama (VJ) testleri uygulanmıştır. Q açısı ve LESS skorları Kinovea ücretsiz yazılımı ile belirlenmiştir. Dikey sıçrama yüksekliğinin hesaplanmasında My Jump 2 mobil ugulaması kullanılmıştır. Elde edilen veriler incelendiğinde Q açısı, LESS skorları ve VJ yüksekliği arasında pozitif ilişki bulunmamaktadır (p>0,05). Q açısı ile inişte ilk temastaki diz valgusu arasında pozitif ilişki bulunmuştur (r=0,292, p<0,05). Sıçramadan önce diz valgusu ile LESS skorları arasında pozitif ilişki bulunmuştur (r=0,482, p<0,05). Araştırma sonuçlarımız incelendiğinde Q açısı, LESS skorları ve VJ yüksekliği arasında ilişki bulunmamaktadır. Q açısı ile inişte ilk temastaki diz valgusunda pozitif ilişki bulunması Q açısının diz valgusuyla ilişkisinden kaynaklanmaktadır. LESS skoruyla sıçramadan önceki diz valgusu arasında pozitif ilişki bulunmuştur. Bu da Q açısının ön çapraz bağ yaralanma risk göstergesi olan LESS skorları üzerindeki etkisini göstermektedir. Q açısını, azaltmak için yapılacak müdaheleler LESS skorlarını, sıçrama ve iniş mekaniğini etkileyebilir.

The Relationship of Q Angle with Jump and Landing Mechanics in Female Volleyball Players

Abstract

During the tests to be performed on athletes, temporal limitations arise. It is not known whether different methods can be safely applied instead of each other. The aim of this study is to investigate the relationship of Q angle with jump and landing mechanics in female volleyball players. The research group consisted of 48 young female athletes who played at the infrastructure level in Istanbul and Kocaeli provinces. Anthropometric measurements, Q angle, Landing Error Scoring System (LESS), Vertical Jump (VJ) tests were applied to the female volleyball athletes participating in the study. The Q angle and LESS scores were determined with the Kinovea free software. The My Jump 2 mobile application was used to calculate the vertical jump height. When the obtained data were examined, there was no positive relationship between Q angle, LESS scores, and VJ height (p > 0.05). A positive relationship was found between the Q angle and the knee deceleration at the first contact upon landing (r = 0.292, p<0.05). A positive relationship was found between knee valgus and LESS scores before deceleration (r = 0.482, p<0.05). When our research results are examined, there is no relationship between Q angle, LESS scores, and VJ height. The presence of a positive relationship between the Q angle and the knee valgus at the first contact upon landing is due to the relationship of the Q angle with the knee valgus. A positive relationship was found between the LESS score and the knee valgus before deceleration. This shows the effect of the Q angle on the LESS scores, which are an indicator of the risk of anterior cruciate ligament injury. Interventions to reduce the Q angle may affect LESS scores, jumps, and landing mechanics.
