概括

与三脚肌肌神经肌肉电刺激 (NMES) 结合手臂循环,与单独使用NMES相比,没有增强扭矩-时间积分 (TTI). 这两种方案都导致了类似的外围疲劳,而没有中央疲劳指标.

科学领域:

运动生理学运动生理学
神经肌肉生理学神经肌肉生理学
康复科学康复科学康复科学

背景情况:

神经肌肉电刺激 (NMES) 用于唤起肌肉收缩,并可能增强扭矩输出.
将NMES与自愿或节奏运动相结合,可能为肌肉功能和耐疲劳性提供协同效益.

研究的目的:

为了比较三肌 surae NMES与手臂循环 (ARM-CYC) 相结合的NMES与阿基里斯肌振动 (WP+VIB) 对扭矩-时间积分 (TTI) 和神经肌肉疲劳的影响.
调查并发的手臂循环是否影响神经肌肉对下肢NMES的反应.

主要方法:

22名健康的年轻人参加了一项随机交叉研究.
使用宽脉冲NMES (WP) 与阿基里斯肌振动 (VIB) 结合,刺激了三肌肌肉.
参与者接受了两个条件:单独WP+VIB和WP+VIB结合节奏臂循环 (ARM-CYC) 在最大自愿同位数收缩 (MVC) 力的20%时.

主要成果:

在ARM-CYC和WP+VIB条件之间没有发现TTI的显著差异 (P=0.371).
这两种情况都导致干预后MVC力和峰值抽扭矩 (P<0.001) 显著下降.
没有观察到自发激活水平 (VAL) 或电肌学幅度的显著变化,唯一的,中间的和侧面的胃膜,表明没有中心疲劳.

结论:

叠加于三肌 surae 的节奏手臂循环 NMES 与振动的 NMES 相比,不会增加扭矩产生.
结合的协议引起类似的外围神经肌肉疲劳作为NMES与单独的振动.
手臂循环缺乏额外的益处可能是由于运动强度低,NMES诱导的天花板效应或抑制输入增加.

Muscle Stimulation Frequency

Muscle Stimulation Frequency

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

Motor Unit Stimulation

Motor Unit Stimulation

When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...

Muscle Recovery and Fatigue

Muscle Recovery and Fatigue

Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...
