: The aim of this study is to determine whether different playing positions in football influence muscle asymmetry, which is a common cause of injuries in football. This study aimed to determine the difference in the functional and lateral asymmetry of the knee joint muscles measured using tensiomyography (TMG) between football players of different playing positions. : This study included 52 professional football players (25.1 ± 4.7 years) divided into three groups according to their playing position: defenders-DF (N = 18), midfielders-MF (N = 15), and forwards-FW (N = 19). Functional and lateral symmetry were investigated by applying TMG on the knee joint muscles Rectus femoris, Vastus medialis, Vastus lateralis, Biceps femoris, and Semitendinosus of the right and left leg, and using the algorithm proposed by the manufacturer and previous studies. : The results of one and two-way ANOVA revealed no significant differences in functional (F = 0.596, = 0.555, on average) and lateral asymmetry (F = 0.888, = 0.497, on average) from the aspect of muscle contraction velocity and muscle stiffness between football players of different playing positions. : The study results show that the specificity of the playing position in football does not influence the functional and lateral asymmetry of the knee joint muscles. However, it has been shown that there is a high percentage of players with lateral (n = 14.5, 39.6%, on average) and specifically functional asymmetry (n = 27, 51.9%, on average).
本研究的目的是确定足球运动中不同的比赛位置是否会影响肌肉不对称性，而肌肉不对称是足球运动中受伤的常见原因。本研究旨在确定使用张力肌电图（TMG）测量的不同比赛位置的足球运动员膝关节肌肉在功能和横向不对称方面的差异。：本研究纳入了52名职业足球运动员（25.1±4.7岁），根据他们的比赛位置分为三组：后卫-DF（N = 18）、中场球员-MF（N = 15）和前锋-FW（N = 19）。通过对左右腿的股直肌、股内侧肌、股外侧肌、股二头肌和半腱肌等膝关节肌肉应用TMG，并使用制造商和先前研究提出的算法，来研究功能和横向对称性。：单因素和双因素方差分析的结果显示，从不同比赛位置的足球运动员在肌肉收缩速度和肌肉僵硬度方面来看，功能（平均F = 0.596，P = 0.555）和横向不对称（平均F = 0.888，P = 0.497）方面没有显著差异。：研究结果表明，足球比赛位置的特殊性不会影响膝关节肌肉的功能和横向不对称性。然而，研究表明，存在较高比例的球员存在横向（平均n = 14.5，39.6%）特别是功能不对称（平均n = 27，51.9%）。
