概括

慢性脚不稳定 (CAI) 的运动员在降落时表现出脚压变化,脚部各个区域的力量和负荷增加. 这表明再次受伤的风险更高,需要量身定制的培训计划.

科学领域:

生物力学生物力学
运动医学运动医学
整形外科整形外科整形外科

背景情况:

慢性脚不稳定 (CAI) 的运动员在降落时表现出异常的脚运动.
降落高度的增加加剧了这些异常运动.
有限的研究存在于CAI运动员在不同高度的脚压分布,阻碍伤害风险评估.

研究的目的:

为了研究与健康对照者相比,在CAI运动员中降落时的脚压分布.
分析不同降落高度 (30厘米与40厘米) 对CAI运动员脚压的影响.
确定与CAI重伤风险增加相关的生物力学标记.

主要方法:

采用了一种2x2混合设计的ANOVA.
20名患有CAI的男性运动员和20名健康对照参与了这项运动.
使用FreeMed巴罗足计平台测量了足部压力分布.

主要成果:

在特定的脚部区域 (MH3,T2-5,RF_L) 发现了峰值力,负载百分比和峰值压力的显著相互作用效应.
与对照人群相比,CAI运动员在T2-5,MH3,MH4,MF_L和RF_L的峰值力,压力和负载百分比显著更高.
在40厘米降落高度的CAI运动员中观察到RF_L和vCOP的负载百分比增加.

结论:

患有CAI的运动员在降落时表现出改变的脚压分布,具有更高的力和负载.
这些发现表明CAI运动员的姿势控制受损,并增加了再伤的风险,特别是在更高的降落高度.
这些结果强调了个性化培训计划的重要性,这些培训计划应对着陆演习期间特定的脚压特征.

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...

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....
