概括

穿着高跟鞋 (HHS) 走路可以减少脚的推开力. 部和膝盖的肌肉补偿,在步行周期期间将能量产生转移到近距离.

科学领域:

生物力学生物力学
人类的机动运动.
肌肉骨适应的情况

背景情况:

高跟鞋 (HHS) 改变了正常行走的生物力学.
减少脚推开功率是HHS的一个已知的影响.
补偿肌肉激活模式仍未得到充分研究.

研究的目的:

为了研究在HHS行走与赤脚在下肢净关节工作和功能的影响.
确定特定的肌肉群,以补偿在HHS行走时脚力量减少.

主要方法:

14名年轻女性赤脚行走,HHS的速度为1.3米/秒.
收集了运动捕捉和地面反应力数据.
反向动力学计算了行走阶段的净关节功率和工作.

主要成果:

在HHS中行走显著降低了脚脚下 flexor峰值功率和在晚期姿势 (A2阶段) 中的工作.
为了补偿,部伸缩器 (H1阶段) 和膝盖伸缩器 (K2阶段) 产生了更大的峰值功率和工作.
flexors (H3阶段) 也增加了功率和工作在晚期的姿势和早期的摇摆.

结论:

在HHS中行走会诱导生物力学可塑性.
净关节功率和行走过程中的工作存在远距离到近距离的再分配.
这突显了部和膝盖肌肉中的补偿策略,以抵消脚功能减少.

Muscles of the Leg that Move the Foot and Toes

Muscles of the Leg that Move the Foot and Toes

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....

Ankle Joint

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
