Effect of Q angle on some performance parameters in adolescent female football players

QA (Q angle) is the line between the combined traction of the quadriceps and the patellar tendon and is associated with the biomechanical function of the lower extremity. The reason we're focusing on the Q angle in women in particular is that we think that in studies women show a higher average QA than men and can give a lot of ideas as a simple precursor parameter. This study aimed to study the effect of the Q angle in Adolescent Women's Footballers on lower extremity vertical jumping performance and the excentric power of the hamstring. Method: A digital manual goniometer was used to measure the QA of individuals, and hamstring eccentric muscle strength NORDBORD device was used for measuring vertical jumping strength with a SmartSpeed Contact Mat half-squat vertical jump test (VJ TEST) The resulting data was normally distributed, and a Pearson correlation test and simple regression tests were applied to the analysis. Results: When the results of simple linear regression analysis of Vertical Jump Performance according to the prediction of the Left Q angle variable were examined, it was seen that the Left Q angle was a significant predictor of the athlete's Vertical Jump performance. In addition, it is seen that there is a moderate positive relationship between Vertical Jump and Asymmetry. Discussions: Football is a competitive game with different dynamics (sprint, change of direction, jumping, collision) and has a higher risk of disability than other sports.
