15-17 Yaş Grubu Futbolcularda Q Açısının Anaerobik Zirve Güce ve Dengeye Etkisi

Öz

Kuadriceps açısı (QA), diz eklemi ve alt ekstremitenin kinezyolojik olarak değerlendirilmesinde sıklıkla kullanılan bir yöntemdir. Özellikle kuvvet, sürat koşusu veya hızlı yön değiştirme, pas atma, zıplama, topa tekme atma veya hızlı adım atma gibi temel futbol eylemleri için önemli faktörler olduğunu göstermiştir. Bu bilgiler ışığında çalışmanın amacı 15-17 yaş grubu altyapı futbolcularda QA’nın anaerobik zirve güce ve dengeye etkisini incelemektir. QA’yı ölçmek amacıyla dijital manuel gonyometre, anaerobik zirve gücü ölçmek amacıyla SmartSpeed Kontakt Matı ile yarım squat dikey sıçrama testi, denge performansını ölçmek amacıyla Y denge testi uygulanmıştır. Elde edilen verilerin normal dağıldığı tespit edilmiş, analizinde Pearson korelasyon testi ve basit regresyon testleri uygulanmıştır. Analiz sonuçlarına göre katılımcıların QA ortalamalarıyla anaerobik zirve güçleri ortalamaları arasında herhangi bir istatistiksel anlamlılığa rastlanmamıştır. Sol QA’ları ile sol anterior uzanma mesafeleri arasında orta düzeyde (R=0.436, R2 =0.190, p=.048), boy ile sağ QA ve sol posteriolateral uzanma mesafeleri arasında orta düzeyde (R=0.543, R2 =0.295, p=.043) anlamlı ilişkiye rastlanmıştır. Yapılan regresyon analizleri sonuçlarına göre katılımcıların sol anterior uzanma mesafesi değişkeninin sol QA’daki toplam varyansın %19’unu, sağ QA ve sol posteriomedial uzanma mesafesi değişkenlerinin de boydaki toplam varyansın yaklaşık %30’unu açıkladığı tespit edilmiştir.

The Effect of Q Angle on Anaerobic Peak Power and Balance in 15-17 Age Group Football Players

Abstract

Quadriceps angle (QA) is a method that is frequently used in the kinesiological evaluation of the knee joint and lower extremity. In particular, strength has been shown to be important factors for basic football actions such as sprinting or changing direction, passing, jumping, kicking the ball, or stepping fast. In light of these informations, the aim of the study is to examine the effect of QA on anaerobic peak power and balance in youth football players aged 15-17. To measure individuals’ QA, a digital manual goniometer was used, half squat vertical jump test with SmartSpeed Contact Mat to measure anaerobic peak power, and Y balance test to measure balance performance were applied. It was determined that the obtained data were normally distributed, and the Pearson correlation test and simple regression tests were applied to the analysis. The analysis showed no statistically significant relationship between the subjects' QA average values and their anaerobic peak power averages. There was a moderate relationship between left QA and left anterior reach distances (R=0.436, R2 =0.190, p=.048), and a moderately significant relationship between height and right QA and left posterolateral reach distances (R=0.543, R2 =0.295, p=.043). As a result, the subjects' left anterior reach distance variable explained 19% of the total variance in the left QA, while the right QA and left posteromedial reach distance variables explained approximately 30% of the total variance in height.
