概括
局部振动 (LV) 可能比静态拉伸 (SS) 更有效地提高肌肉灵活性. 这项研究使用肌肉超声波 (MUS) 来评估下肢灵活性,发现LV优于SS.
科学领域:
- 生物力学和运动生理学
- 肌肉骨超声波成像 肌肉骨超声波成像
背景情况:
- 局部振动 (LV) 是一种提高灵活性的潜在方法,但与传统静态拉伸 (SS) 相比,其有效性尚未得到充分证实.
- 了解LV对肌肉特性的直接影响对于优化训练方案至关重要.
研究的目的:
- 为了比较短期LV和SS对健康个体下肢灵活性的直接影响.
- 利用先进的肌肉超声波 (MUS) 技术,包括三维剪切波弹性 (3D-SWE) 和多普勒MUS,进行客观评估.
主要方法:
- 一个随机交叉试验,同一个主体设计,涉及14名健康参与者.
- 干预包括1分钟的LV (30赫兹,3毫米振幅) 或SS,应用于双边肌肉.
- 使用3D-SWE和多普勒MUS评估肌肉弹性和血液流动,并进行站立和伸缩测试.
主要成果:
- 无论是LV还是SS都降低了灵活性,但与SS相比,LV的下降幅度要小得多.
- LV显著增加了胃肌的功率多普勒指数 (PDI) 和降低了剪波弹性图 (SWE) 值,表明肌肉弹性发生了变化.
结论:
- 局部振动可能比静态拉伸提供更有效的方法,以改善下肢的直接灵活性.

01:22Muscle Stimulation Frequency
4.3K
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.

At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...

5.5K
The period of muscle contraction primarily influences the duration of stimulation at the neuromuscular junction (NMJ), the presence of free calcium ions in the sarcoplasm, and the availability of energy or ATP to support contractions.
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open....
