延迟性肌肉酸痛与运动性骨骼肌记忆

Delayed onset muscle soreness and exercise-induced skeletal muscle memory

背景:不习惯的运动使骨骼肌损伤,但可以产生一种减轻肌肉再损伤减轻疼痛的特定训练效果-肌肉记忆。目的:基于延迟性肌肉酸痛的病因,综述延迟性肌肉酸痛中骨骼肌记忆的存在及其可能机制,提出防治延迟性肌肉酸痛的新见解。方法:第一作者以“DOMS,Skeletal muscle memory,Exercise Skeletal muscle adaptation,Repeat turn effect,exercise and autophagy,Autophagy and inflammation”为英文检索词,“延迟性肌肉酸痛,骨骼肌记忆,运动性骨骼肌适应,重复回合效应,运动与自噬,自噬与炎症”为中文检索词,检索PubMed、Embase、Web of Science、中国知网及万方数据库1990年1月至2022年12月发表的相关文献,最终纳入102篇文献进行综述。结果与结论:目前认为延迟性肌肉酸痛是由于代谢紊乱、机械损伤和氧化应激所致的急性期炎症反应,而运动性骨骼肌记忆具有减轻延迟性肌肉酸痛、减轻运动再损伤的作用,当离心训练的持续时间、频率和强度逐渐增加时,损伤症状可以被最小化,甚至可以避免。因此基于运动性骨骼肌记忆机制,寻找防治或减轻延迟性肌肉酸痛及运动性肌肉损伤的方法是未来的研究方向。综述的主要目的:①明确运动性骨骼肌记忆的存在;②探讨运动性骨骼肌记忆的可能机制,并提出该记忆与骨骼肌自噬的关系;③通过改善骨骼肌自噬水平为延迟性肌肉酸痛的防治提供新策略。

BACKGROUND:Unaccustomed exercise triggers skeletal muscle damage,but produces a specific training effect that reduces muscle re-injury to reduce pain-muscle memory.OBJECTIVE:Based on the etiology of delayed onset muscle soreness,to review the existence and possible mechanism of skeletal muscle memory in delayed onset muscle soreness and to present new insights into the prevention and treatment of delayed onset muscle soreness.METHODS:The first author searched in PubMed,Embase,Web of Science,CNKI and WanFang databases for relevant literature published from January 1990 to December 2022.The keywords were“DOMS,skeletal muscle memory,exercise skeletal muscle adaptation,repeat turn effect,exercise and autophagy,autophagy and inflammation”in English and Chinese,respectively.A total of 102 articles were finally included for review.RESULTS AND CONCLUSION:The etiology of delayed onset muscle soreness is currently believed to be an acute inflammatory response due to metabolic disorders,mechanical injury and oxidative stress,while exercise-induced skeletal muscle memory can reduce delayed onset muscle soreness and exercise re-injury.When the duration,frequency and intensity of centrifugal training are gradually increased,symptoms of the injury can be minimized or even avoided.Therefore,based on the mechanism of exercise-induced skeletal muscle memory,it is the future research direction to find more effective ways to prevent and alleviate exercise-induced muscle injury.This review aims to(1)clarify the existence of exercise-induced skeletal muscle memory;(2)explore the possible mechanisms of exercise-induced skeletal muscle memory and propose the relationship between this memory and skeletal muscle autophagy;and(3)provide new strategies for the prevention and treatment of delayed onset muscle soreness by improving the level of skeletal muscle autophagy.
