The aim of this research was to evaluate the reliability of the measurements of biomechanical parameters of the muscles of athletes representing different disciplines as well as untrained people. Ninety-four young, healthy male individuals participated in the study and were divided into five subgroups: footballers ( = 25), volleyballers ( = 14), handballers (= 19), MMA fighters ( = 16), and undrained group ( = 20). All of the participants underwent measurements of stiffness (S), muscle tone (T) and elasticity (E) by two independent measurers using MyotonPro equipment. Analysis was conducted on two different parts of the quadriceps femoris: rectus femoris (RF) and vastus medialis (VM. Consequently, the comprehensive analysis comprised 564 measurements (94 participants * 3 parameters = 282 * 2 measurers = 564). The results proves high reliability of the myotonometry (Pearson's CC over 0.8208-0.8871 for different parameters, ICC from to 0.74 to 0.99 for different muscles and parameters) excluding only stiffness for the VM which was characterized withlow ICC of 0.08 and relatively highest between the examined parameters MAE% of 8.7% which still remains low value. The most significant differences between the parameters in examined groups were observed between MMA fighters and volleyballers in terms of muscle tone and elasticity of the VM (correlation of 0.14842 and 0.15083 respecitively). These results confirm the usability of myotonometry in measuring the biomechanical properties of the muscles in different sports groups and confirm the independence of the results obtained from the person performing the measurement.
本研究的目的是评估代表不同运动项目的运动员以及未受过训练的人的肌肉生物力学参数测量的可靠性。94名年轻、健康的男性个体参与了该研究，并被分为五个亚组：足球运动员（n = 25）、排球运动员（n = 14）、手球运动员（n = 19）、综合格斗选手（n = 16）和未受过训练组（n = 20）。所有参与者均由两名独立测量人员使用MyotonPro设备进行了僵硬度（S）、肌张力（T）和弹性（E）的测量。对股四头肌的两个不同部位进行了分析：股直肌（RF）和股内侧肌（VM）。因此，综合分析包括564次测量（94名参与者×3个参数 = 282×2名测量人员 = 564）。结果证明了肌张力测量法具有很高的可靠性（不同参数的皮尔逊相关系数CC超过0.8208 - 0.8871，不同肌肉和参数的组内相关系数ICC从0.74到0.99），仅VM的僵硬度除外，其ICC为0.08，在所检查的参数中相对最高，平均绝对误差百分比（MAE%）为8.7%，但仍为低值。在所检查的组中，综合格斗选手和排球运动员之间在VM的肌张力和弹性方面观察到参数之间最显著的差异（相关系数分别为0.14842和0.15083）。这些结果证实了肌张力测量法在测量不同运动组肌肉生物力学特性方面的可用性，并证实了测量结果与测量人员的独立性。
