概括
在脚升高10厘米时进行桥梁运动,可以增强关节最大 (GM) 和多 (MF) 肌肉活动. 这种脚高度也改善了GM与双腿肌 (BF) 肌肉活动比率,优化了部稳定性.
科学领域:
- 生物力学 生物力学
- 运动生理学 运动生理学
- 肌肉骨研究 研究
背景情况:
- 大关节 (Gluteus maximus,GM) 和大腿 (biceps femoris,BF) 是部稳定性和运动性的关键.
- 桥练习期间的脚高度会影响下肢肌肉的激活.
研究的目的:
- 为了研究GM,BF和多 (MF) 肌肉活动在桥练习期间在不同的脚高度.
- 为了确定最佳的脚高度来增强特定的肌肉参与.
主要方法:
- 15名健康的受试者在0厘米,5厘米和10厘米高度的脚上进行桥梁练习.
- 电肌图 (EMG) 测量了GM,MF和BF肌肉活动.
- 使用了随机顺序的脚高度条件.
主要成果:
- 与0厘米和5厘米相比,10厘米的脚高度显著增加了转基因肌肉活动.
- 在10厘米的脚高度,MF肌肉活动比0厘米高.
- 与0厘米相比,BF肌肉活动在10厘米的脚高度下降.
- 在足高10厘米时,GM/BF肌肉活动比率显著更高.
结论:
- 在桥练习中将脚抬高到10厘米,可以选择性地促进GM和MF肌肉活动.
- 这种修改优化了GM/BF肌肉活动比率,可能增强关节功能.
- 建议在足高10厘米的桥练习有针对性地加强部和多部.

01:28Muscles of the Leg that Move the Foot and Toes
1.0K
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....

01:26Cross-bridge Cycle
115.8K
As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.
