背景情况:

支尺度 (SS) 是体操中一个基本的上肢技能.
预先条件强化练习 (PSE) 常用于为运动员准备SS.
在模仿SS的肌肉参与方面,PSE的有效性尚未得到充分理解.

研究的目的:

为了比较肌肉刺激,协同激活指数和SS及其相关PSE之间的肌肉协同作用.
确定PSE是否为体操运动员准备足够的体操运动员,以满足SS的特定需求.

主要方法:

电肌图 (EMG) 活动记录了七名精英环球专业体操运动员的八个关键上肢肌肉.
参与者执行了SS和五个不同的PSE.
分析了肌肉协同作用和协同激活比率,并在SS和PSE之间进行了比较.

主要成果:

在SS和PSE之间的梯形肌,胸肌和双肩肌的肌肉活动中观察到显著的差异.
协同激活模式,特别是双肩/三头骨和/骨的比率,有显著的差异.
肌肉协同效应分析显示,与SS相比,PSE的肌肉激活模式具有不同的同时肌肉激活模式.

结论:

目前的PSE不能完全复制体操SS所需的复杂肌肉激活和协同作用.
培训计划可能需要修改,以纳入与SS特定肌肉招募模式更接近的练习.
这项研究为PSE选择提供了更有针对性的方法,以提高体操运动员的SS表现.

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...

Isotonic and Isometric Muscle Contractions

Isotonic and Isometric Muscle Contractions

Two primary types of muscle contractions are isotonic and isometric, each serving unique functions and involving distinct mechanisms. Both isotonic and isometric contractions are integral to the body's complex system of movement and stability. Isotonic exercises contribute significantly to functional strength and movement, while isometric contractions are crucial for maintaining posture and joint stability.
Isotonic contractions
Isotonic contractions occur when a muscle changes length while...
