概括
桥梁练习与脚 (脚平) 最大限度地激活腿筋,而背 (脚向上) 增强四头肌,引体和斜部参与,用于康复和运动表现.
科学领域:
- 生物力学 生物力学
- 运动生理学 运动生理学
- 运动科学 运动科学 运动科学
背景情况:
- 桥梁练习在物理治疗和运动训练中很常见.
- 脚定位对桥梁运动期间肌肉激活的影响尚未得到充分研究.
- 了解这些影响可以优化炼选择.
研究的目的:
- 为了研究两个脚位置,脚下 (PF) 和背部 (DF),如何影响核心和下肢肌肉 (EMG) 在各种桥梁练习期间的电肌图 (EMG) 活动.
- 为了比较PF和DF之间的肌肉招募模式,跨越五种常见的桥梁变体 (双腿和单腿).
主要方法:
- 20名健康的参与者进行了5项异比桥梁练习 (一腿膝盖曲/伸展,两腿标准,两腿带带,两腿带球).
- 收集了来自14个肌肉的EMG数据,包括四头肌,腿筋,部绑架器,引器,直立器脊柱,背和腹部.
- 对EMG信号进行了正常化,以最大自发同度收缩 (MVICs),并使用对联t测试 (p < 0.01) 分析了PF和DF之间的差异.
主要成果:
- 与背部弹 (DF) 相比,横侧弹 (PF) 在所有五种练习中都显著增加了腿筋 (ST,BF) 激活.
- 在特定的单腿运动中,背 (DF) 显著增加四头肌 (VM,VL,RF) 和 adductor (ADD) 的激活.
- 背部屈曲 (DF) 在某些单腿桥梁变化期间,在外部斜 (EO) 和内部斜 (IO) 中也显示出更大的激活.
结论:
- 在桥梁练习期间,平脚 (脚平) 优越于腿筋招募.
- 在特定的桥梁运动中,背部屈曲 (脚向上) 更有效地参与四头骨,部附加器和斜骨 (内部和外部).
- 脚的位置是调节桥梁运动期间肌肉激活的关键变量,为康复和表现提供了明显的好处.

01:28Muscles of the Leg that Move the Foot and Toes
1.4K
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....

The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

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...
