概括
足部内在肌肉的尺寸,如曲器幻觉短 (FHB) 和曲器幻觉横头 (ADDH-TH) 影响着脚曲器的整体强度 (TFS-All). 然而,个体脚强度 (TFS-大,TFS-小) 与特定的肌肉大小没有明确的联系.
科学领域:
- 生物力学 生物力学
- 人类解剖学 人类解剖学
- 运动生理学 运动生理学
背景情况:
- 脚曲器强度 (TFS) 对于评估下肢功能至关重要.
- 现有的研究还不清楚脚曲肌的大小如何与不同脚的力量产生有关.
研究的目的:
- 为了研究脚曲肌的大小和强度之间的关系.
- 为了确定特定的脚曲器强度 (TFS-All,TFS-Great,TFS-Lesser) 与相应的内在脚肌的大小是否相关.
主要方法:
- 磁共振成像 (MRI) 测量了20名健康年轻男子内在脚肌的最大解剖截面面积 (ACSA_max).
- 一个定制的脚动力计评估了三种类型的脚曲器强度:TFS-All,TFS-Great和TFS-Lesser.
主要成果:
- TFS-All显示了与添加器幻觉横向头部 (ADDH-TH) 和柔性幻觉短 (FHB) 的ACSA_max的显著相关性.
- TFS-Great和TFS-Lesser与其解剖学专业肌肉的大小没有显著的相关性,TFS-Lesser和内骨肌肉是一个小的例外.
结论:
- FHB和ADDH-TH肌肉的大小似乎是整体脚曲器强度 (TFS-All) 的关键决定因素.
- 各个脚的特异性强度 (TFS-大,TFS-小) 与相应肌肉的大小没有很强的关联,可能是由于神经或解剖激活限制.

Muscles of the Leg that Move the Foot and Toes
1.2K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
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....

Bones of the Lower Limb: Tibia and Fibula
2.7K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
