概括
具有较大的脚关节硬度的休跑步者往往会有脚跟撞击模式. 没有后脚的跑步者具有较薄的阿基里斯肌 (AT) 会出现脚的撞击,而具有较厚的AT的跑步者则会增加脚的硬.
科学领域:
- 生物力学 生物力学
- 运动科学 运动科学 运动科学
- 整形外科 整形外科 整形外科
背景情况:
- 了解肌特性与跑步生物力学之间的相互作用对于预防伤害至关重要.
- 足部冲击模式和脚关节机制是影响运行经济和受伤风险的关键因素.
研究的目的:
- 调查阿基里斯肌 (AT) 尺寸,脚关节硬度和休跑步者的足迹模式之间的关系.
- 为了区分后脚和非后脚攻击者之间的这些关系.
主要方法:
- 招募了107名休跑步者 (后脚和非后脚运动员).
- 阿基里斯肌尺寸 (长度,厚度,动力臂) 用超声波和运动捕捉测量.
- 在自选速度的跑步试验中,评估了脚关节硬度和脚踏模式.
- 部分相关系数被用来分析变量之间的关系.
主要成果:
- 在后脚 (r=0.232,p=0.032) 和非后脚跑步者 (r=-0.811,p<0.001) 中,发现了关节硬度和落脚模式之间的显著相关性.
- 在非后脚跑者中观察到阿基里斯肌厚度和足部冲击指数之间的关系 (r=-0.486).
- 具有更明显的脚跟打击的跑步者表现出更大的脚关节硬.
- 脚撞击的非后脚跑步者有更薄的阿基里斯肌,而那些肌较厚的跑步者则表现出更大的脚关节硬.
结论:
- 脚关节硬与不同跑步风格的脚步模式有很大关系.
- 阿基里斯肌的厚度与非后脚跑步者的脚撞击模式有关,这表明在减震和推进方面可能发挥作用.
- 这些发现突出了后脚和非后脚跑步者在肌特性和关节力学方面采用的不同的生物力学策略.

Ankle Joint
1.6K
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
1.7K
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....

Pulse Assessment Sites
1.1K
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...
