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.
