Comparison and Relationship of Quadriceps Femoris Angle, Muscle Strength, and Balance in Athletes and Non-Athletes

Objective Q-angle is an important parameter to assess quadriceps muscle's function and its effect on knee. The present study aims to investigate the potential relationships between Q-angle, muscle strength, and balance in both athlete and non-athlete populations. Methods Fifty-six athletes and non-athletes aged between 18 and 20 were included in this cross-sectional study. The Q-angle of each participant was measured using a universal goniometer. Muscle strength was evaluated using hand-held dynamometer, and static and dynamic balance were assessed using the one-leg stand test and Y balance test, respectively. Results Our findings revealed that athletes had a significantly smaller Q angle than non-athletes (p
