文题释义:
兴奋-收缩耦联:
是指将电兴奋过程和机械收缩联系起来的中介过程。其中介因子是钙离子,结构基础是三联管结构。其包括3个步骤:电兴奋通过横管系统传导到肌细胞深处;肌质网对钙离子的释放和再摄取;肌肉的收缩和舒张。
反应时:是指从接受刺激到机体做出反应动作所需的时间,也就是从刺激到反应之间的时距。它包括了感觉器官感受到刺激所需要的时间、大脑加工消耗的时间、神经传导的时间以及肌肉产生反应的时间。主要反映人体神经与肌肉系统的协调性和快速反应能力。

 

摘要
背景:
随着运动医学和康复医学的发展,国外对肌肉电-机械延迟的研究愈加深入,应用愈加广泛,并将其作为评价神经肌肉功能状态的重要指标之一,而国内对肌肉电-机械延迟缺乏关注,少有学者开展相关研究。
目的:回顾近年来与电-机械延迟相关的国内外相关文献,系统综述电-机械延迟的发生机制、影响因素及应用现状,以期指导临床实践和研究。
方法:以“电-机械延迟”和“Electromechanical Delay;Electro-mechanical response time”为检索词,计算机检索1979年2月至2017年2月CNKI数据库、万方数据库、PubMed数据库收录的有关电-机械延迟的研究文献,排除报道时间较早或重复的研究,共44篇文献符合标准,中文3篇,英文41篇。
结果与结论:研究表明,电-机械延迟的发生机制已经基本明确,肌纤维类型和肌肉疲劳程度会对电-机械延迟造成影响,但是影响机制还有待进一步明确;性别和年龄等因素对电-机械延迟的影响仍存在争议。对电-机械延迟的应用也不再仅限于评价运动员的反应能力,其在运动损伤机制和损伤后康复疗效评价两方面的应用也越来越深入。

Abstract:

BACKGROUND: With the development of sports medicine and rehabilitation medicine, electromechanical delay has been looked as an important index for evaluating the neuromuscular function at abroad. But the relevant research is little reported in China.
OBJECTIVE: To review the literatures related to electromechanical delay published in recent years, and to explore the mechanisms, influential factors and the application status of the electromechanical delay, thereby providing reference for clinical practice and research.
METHODS: A computer-based search of CNKI, WanFang and PubMed databases was performed for articles addressing electromechanical delay published from February 1979 to February 2017. The keywords were ”electromechanical delay, electro-mechanical response time” in English and Chinese, respectively. Repeated and old studies were excluded, and finally 44 eligible literatures were included, including 3 Chinese and 41 English articles.
RESULTS AND CONCLUSION: The mechanisms of electromechanical delay have been clarified. The type of muscle fiber and the level of muscle fatigue can influence electromechanical delay, but the underlying mechanisms still remain unclear. Whether age and gender make effect on electromechanical delay is controversial. Electromechanical delay is not only used for evaluating the athletes’ ability to reaction, but also wildly used to investigate the mechanism of various sports injuries and evaluate the effectiveness of rehabilitation.
