The aim of this study was to monitor seasonal changes in the mechanical and neuromuscular characteristics of the knee flexor muscles with tensiomyography, the biceps femoris (BF) and semitendinosus (ST) muscles, of 27 soccer players. All male professional soccer players (age 25 ± 4 years) were measured at the beginning of the preseason (second week) and in the competitive season (10 weeks later). The variables contraction time (Tc) and muscle displacement (Dm) showed significant differences in some muscles, and in others they indicated a tendency to change. In general, the BF improved (more explosive and better muscle tone) and the ST worsened (slower and worse muscle tone) its values during the season. The findings of this study suggest that usual daily soccer training and weekly competition might produce antagonistic changes between the knee flexor muscles.
本研究的目的是通过张力肌电图监测27名足球运动员股二头肌（BF）和半腱肌（ST）这两块膝关节屈肌的力学和神经肌肉特性的季节性变化。所有男性职业足球运动员（年龄25±4岁）在季前赛开始时（第二周）和比赛赛季（10周后）进行了测量。收缩时间（Tc）和肌肉位移（Dm）变量在某些肌肉中显示出显著差异，而在其他肌肉中则显示出变化趋势。总体而言，在赛季中BF的值有所改善（爆发力更强，肌肉张力更好），而ST的值则有所恶化（速度更慢，肌肉张力更差）。本研究结果表明，日常的足球训练和每周的比赛可能会使膝关节屈肌之间产生拮抗变化。
