概括
在年轻人中,较高的体脂百分比显著延迟了关节肌肉反应时间. 这表明多余的脂肪会影响神经肌肉功能,影响移动性和运动控制.
科学领域:
- 运动生理学 运动生理学
- 生物力学 生物力学
- 神经肌肉功能 神经肌肉功能
背景情况:
- 肥胖与影响移动性和运动控制的功能障碍有关.
- 过多的身体脂肪可能会损害神经肌肉激活,但它对年轻成年人的脚肌肉反应时间的影响还未得到充分研究.
研究的目的:
- 分析年轻成年人之间关节肌肉反应时间的差异,身体脂肪百分比不同 (正常,升高,非常升高).
主要方法:
- 与48名年轻成年人进行的横截面观察研究.
- 根据身体脂肪百分比进行分类.
- 表面电肌图测量了前节,长节和中部胃半节的反应时间,这些反应时间是在突然的脚逆转测试中进行的.
主要成果:
- 对于所有测量到的脚肌肉,在不同组中观察到反应时间的显著差异 (p <0.001对于前脚和中侧腹肌;p = 0.010对于长腿肌).
- 身体脂肪非常高的年轻人表现出延迟的肌肉激活.
- 回归分析表明,与正常脂肪群相比,在所有三个脚肌肉中,非常高的身体脂肪百分比与明显更长的反应时间有关.
结论:
- 身体脂肪百分比增加与关键脚肌肉的反应时间延长有关.
- 研究结果强调了身体脂肪百分比在评估神经肌肉性能和为年轻人设计干预措施时的重要性.

01:10Ankle Joint
2.8K
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...

01:28Muscles of the Leg that Move the Foot and Toes
3.9K
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....
