概括
木制拖鞋显著改变马的步态动力学,显示出明显的地面反应力模式. 这些可预测的变化可能会减少脚压力,使它们与其他类型的鞋类有所区别.
科学领域:
- 马类生物力学 马类生物力学
- 兽医整形医学 兽医整形医学
- 动物的运动分析.
背景情况:
- 马的鞋子显著影响了对马施加的力量.
- 了解这些力量对于预防脚和优化表现至关重要.
- 不同的鞋子设计,如心棒,蛋棒,开脚跟和木制拖鞋,可能会引起独特的动力反应.
研究的目的:
- 为了比较马匹的地面反应力 (GRF) 和步态动力学,马匹穿着不同类型的鞋 (心棒,蛋棒,开脚跟,木制) 和没有鞋.
- 为了确定特定的制鞋条件是否会导致可预测的动力特征.
- 为了研究在各种穿鞋条件下GRF载体角的持续时间.
主要方法:
- 前肢GRF被记录在六匹轻品种马的前肢GRF中,它们穿过一个强力平台.
- 马被测试无鞋子和四种不同类型的鞋子 (蛋条,心条,开脚跟,木塞).
- 使用统计模型和随机森林分类器分析了包括峰值力,冲动,立场时间和GRF向量角度在内的动态结果措施.
主要成果:

Ankle Joint
3.4K
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...

Muscles of the Leg that Move the Foot and Toes
5.1K
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....
