皮带改变了跑步肌肉激活模式,减少了立场阶段的膝盖伸展力. 这表明皮带可能有助于减少四头肌在跑步活动期间的肌肉张力.
科学领域:
- 生物力学 生物力学
- 神经肌肉控制控制神经肌肉控制
- 运动医学 运动医学
背景情况:
- 膝盖内皮带广泛用于膝盖受伤的跑步.
- 以前的研究集中在个体肌肉上,而不是神经肌肉控制策略.
- 肌肉协同作用是神经系统运动控制的一个关键概念.
研究的目的:
- 调查皮带在跑步过程中对肌肉协同作用的影响.
- 分析肌肉激活模式和膝关节机械学的变化.
主要方法:
- 十七名参与者在带有或没有带有下皮带的情况下跑步.
- 收集了动力学,动力学和电肌学数据.
- 非负矩阵因子化提取的肌肉协同作用;OpenSim估计的膝关节参数.
主要成果:
- 肌底皮带并没有改变肌肉模块的数量或动态运动控制指数 (DMC).
- 在立场阶段模块内膝盖延伸器的权重减少了带.
- 推进过程中的峰值时激活被延迟,立场阶段膝盖延伸时刻被减少.
结论:
- 肌底皮带改变肌肉激活模式和权重,而不是整体模块化.
- 这些变化表明了减少四头肌肌力力量的潜在机制.
- 皮带可以提供一种非侵入性的方法来管理在跑步期间的膝盖延伸器负荷.

Muscles of the Leg that Move the Foot and Toes
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....
Muscles that Move the Leg
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
