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.
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.
Our findings revealed that athletes had a significantly smaller Q angle than non-athletes (p < 0.05). Furthermore, male participants had both higher muscle strength and better static balance with eyes closed than female participants (p < 0.05). Similarly, athletes had both higher muscle strength and better static balance than non-athletes (p < 0.05). Moreover, we found that the dominant limb had a significantly smaller Q angle than the non-dominant limb (p < 0.05). However, we did not observe a significant relationship between Q angle and dynamic balance (p > 0.05).
Our study suggests that individuals who participate in sports have lower Q angle values than those who do not participate in sports. Additionally, gender differences may exist in muscle strength and static balance. Furthermore, the Q angle was found to be lower in the non-dominant extremity compared to the dominant extremity. Finally, our study revealed a significant association between Q angle and knee muscle strength and static balance. Further research is needed to elucidate the underlying mechanisms of these relationships.
Q角是评估股四头肌功能及其对膝关节影响的重要参数。本研究旨在探讨运动员和非运动员群体中Q角、肌肉力量和平衡之间的潜在关系。
本横断面研究纳入了56名年龄在18至20岁之间的运动员和非运动员。使用通用测角仪测量每位参与者的Q角。使用手持测力计评估肌肉力量，分别使用单腿站立测试和Y平衡测试评估静态和动态平衡。
我们的研究结果显示，运动员的Q角明显小于非运动员（p < 0.05）。此外，男性参与者的肌肉力量和闭眼时的静态平衡均优于女性参与者（p < 0.05）。同样，运动员的肌肉力量和静态平衡也优于非运动员（p < 0.05）。此外，我们发现优势肢体的Q角明显小于非优势肢体（p < 0.05）。然而，我们未观察到Q角与动态平衡之间存在显著关系（p > 0.05）。
我们的研究表明，参与运动的个体的Q角值低于不参与运动的个体。此外，肌肉力量和静态平衡可能存在性别差异。此外，发现非优势肢体的Q角低于优势肢体。最后，我们的研究揭示了Q角与膝关节肌肉力量和静态平衡之间存在显著关联。需要进一步研究以阐明这些关系的潜在机制。
