肌肉活动

By the change he has effected in his mode of life, man is no longer necessarily dependent on his physical organism for the means of his subsistence, and in cases where he is still so dependent, such as those of the agriculturist, the artisan and others who earn a living by manual labour, he employs his muscles in new ways, in mechanical repetitions of the same act, or in modes of labour which are far removed from those called forth by primitive conditions.

随着人类生活方式的变化，他已经无需倚赖身体斗争谋生了。而对于农民、手工艺人及其他依然需要通过体力劳动谋生的人来说，肌肉的使用也发生了变化，有时不断机械重复同一动作，有时则采用与原始状态下的活动完全不同的全新方式工作。

BACKGROUND: F-wave is a late muscle response which results from the antidromic activation of spinal motorneurones following peripheral nerve supramaximal electrical stimulation,and influenced by the balance of excitatory and inhibitory postsynaptic potentials on spinal motomeurons.

背景：F波是末梢神经接受最大电刺激，从肌肉诱发出来的后期合成活动电位之一，是脊髓运动神经元突触后电位的反映，对F波的研究已经被作为衡量脊髓运动神经元兴奋性的一种手段。

Automatic backslap is the best way to prevent bedsore and muscle atrophy because it can improve the activity of back＇s EMG and blood circulation.

自动拍背可促进背部肌肉之电性活动，改善血液循环，自动拍背时间以6min为最佳。

The mechanism of the myocytes in and out coronary sinus develop ectopia arrhythmia is different.

冠状窦及其周围组织作为兴奋起源点可以分为两种，其中一个区域，即冠状窦外右房心肌具有自律性，而冠状窦肌肉结构的心肌只在触发活动时方出现自发电活动。

The pathological diagnosis should include:(1) the electromyographic recording and ultrasound imaging of local twitch responses,(2) the EMG recording of spontaneous electrical activity at multiple active loci in the MTrP, and (3) the biopsies of MTrP that show contraction knots and giant round muscle fibers.

病理学的诊断应该包括：(1)局部抽搐反应的肌电图记录与超音波影像，(2)在肌筋膜激痛点里的多发性活动性小点上之自发性电位活动的肌电图纪录，(3)肌筋膜激痛点的切片检查显现出收缩结节和大而圆的肌肉纤维。

When playing sports, muscle fatigue as well as vigorous use of the muscles can cause cramping.

当进行体育活动时，肌肉疲劳和肌肉的激烈运动都可能造成抽筋。

Maybe they, have the idea that control can be best achieved by tensing up various sets of antagonistic muscles simultaneously.

所以，他们用拉紧肌肉代替了用适宜的技能和最小限度的肌肉的活动。

A runner exercises before a race to prevent his muscles from tensing up.

赛跑运动员在比赛前要活动活动，以放松肌肉。

Kids should get a mix of aerobic, muscle-building (rope-climbing) and bone-strengthening activity.

儿童应该综合获得有氧活动、肌肉锻炼，骨质增强活动。

Stretching is a major piece of the foundation of health for a number of reasons: it improves flexibility, it makes other exercises easier, it improves range of movement, it reduces muscle tension, it improves circulation (which directly relates to improved energy levels), and it improves muscular coordination.

基于以下这些理由，伸展运动是健康基础的一个主要组成部分：它可以改善柔韧性，使进行其他锻炼活动变得更加容易，扩展动作的范围，缓解肌肉的紧张，促进循环（从而直接提升了能量等级），改善肌肉功能的协调性。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
