Kadın Futbol Oyuncularının Hamstring/Quadriceps Oranı, Pik Torka Ulaşma Süresi Ve Pik Torktaki Eklem Açısı Özelliklerinin İncelenmesi

Öz

Quadriceps ve hamstring kaslarının fonksiyonel olarak değerlendirilmesi için pik torka ulaşma süresi ve pik torktaki eklem açısı parametrelerinin önemli veriler sunduğu düşünülmektedir. Literatürde bu parametreler kullanılarak yapılan çalışmalara az rastlandığı görülmektedir. Kadın futbol oyuncularının hamstring/quadriceps (H/Q) oranı, pik torka ulaşma süresi ve pik torktaki eklem açısı parametreleri arasındaki ilişkinin incelenmesi bu çalışmanın amacını oluşturmaktadır. Araştırmanın örneklem grubu, ulusal kadınlar liginde (3. Lig) performans sergileyen 20 kadın futbolcudan oluşmaktadır. Futbolcuların diz eklemlerine ait ölçümler, 60°/sn. ve 180°/sn. açısal hızlardaki konsantrik/konsantrik protokol ile gerçekleştirilmiştir. Futbolculardan elde edilen verilerin normal dağılıma uygunluğu Shapiro-Wilk Test ile incelendi ve normal dağılım gösterdikleri tespit edildi. Parametreler arasındaki ilişkiler ise Pearson korelasyon katsayısı ile incelendi. Analiz sonuçlarına göre, nondominant 180°/sn. H/Q oranı ile 180°/sn. açısal hızdaki fleksör kasın pik torka ulaşma süresi arasında ve dominant 180°/sn. H/Q oranı ile 180°/sn. fleksiyon anındaki pik torka ulaşılan açı değeri arasında istatistiksel olarak anlamlı bir ilişki olduğu tespit edilmiştir (p<0.05). Diğer parametrelerde ise bir ilişkiye rastlanmamaktadır (p>0.05). Sonuç olarak, kadın futbolcuların H/Q oranlarının fonksiyonel kuvvet parametreleri (pik torka ulaşma süresi ve pik torktaki eklem açısı) ile tam olarak ilişkilendirilemeyeceği ve fonksiyonel performansın farklı yaklaşımlarla değerlendirilmesi gerektiği söylenebilir.

Investigation of The Hamstrıng/Quadriceps Ratio, Time to Peak Torque and Joint Angle at Peak Torque Characteristics of Female Soccer Players

Öz

It is thought that time to peak torque and joint angle at peak torque parameters provide important data for the functional evaluation of quadriceps and hamstring muscles. It is known that studies with these parameters are rare in the literature. The aim of this study is to investigate the relationship between hamstring/quadriceps (H/Q) ratio, time to peak torque and joint angle at peak torque parameters of female football players. The sample group of the study consisted of 20 female footballers performing in the national women's league (3rd Division). Measurements of the footballers’ knee joints, as 60°/sec. and 180°/sec. angular velocities were performed with the concentric/concentric protocol. The conformity of the data obtained from the footballers to the normal distribution was analized with the Shapiro-Wilk Test and it was determined that they showed a normal distribution. Relationships between parameters were analyzed with Pearson correlation coefficient. According to the results of the analysis, it was determined that there is a statistically significant relationship between the non-dominant 180°/sec H/Q ratio and the time to peak torque of the flexor muscle at 180º/sec angular velocity, and between the dominant 180°/sec H/Q ratio and the joint angle at peak torque 180°/sec flexion. (p<0.05). No relationship was found in other parameters (p>0.05). As a result, it can be said that the H/Q ratios of female football players are not related to functional strength parameters (time to peak torque and joint angle at peak torque) and functional performance should be evaluated with different approaches.
