Abstract

The objective of this study was to determine if performing electrical stimulations (E-STIM) under blood flow restriction (BFR) would result in a greater protective effect against symptoms of muscle damage. 18 individuals (9 females) completed a damaging bout of exercise followed by a low frequency E-STIM treatment protocol on both arms, one of which was completed under BFR. The treatment protocol was then repeated 24-hours post-exercise. There were main effects of time for muscle thickness (pre: 3.5 cm; 48 h post: 3.8 cm; BF₁₀ = 88.476), discomfort (pre: 0.0 au; 48 h post: 4.2 au; BF₁₀ = 241.996), and isometric strength (pre: 278 N; 48 h post: 232 N; BF₁₀ = 10,289.894) which all changed as a result of the damaging exercise protocol, but there were no differences between conditions [all Bayes Factors (BF₁₀) < 0.28]. The effectiveness of low frequency E-STIM for preventing the onset of exercise-induced muscle damage would not appear to be enhanced if performed under BFR.

通过限制血流的电刺激来预防或减轻肌肉损伤症状

本研究旨在确定在血流受限（BFR）情况下进行电刺激（E-STIM）是否会对肌肉损伤症状产生更大的保护作用。18 人（9 名女性）完成了一次损伤性运动，然后对双臂进行了低频 E-STIM 治疗，其中一次是在血流受限的情况下完成的。然后在运动后 24 小时重复治疗方案。肌肉厚度（运动前：3.5 厘米；运动后 48 小时：3.8 厘米；BF10 = 88.476）、不适感（运动前：0.0 au；运动后 48 小时：4.2 au；BF10 = 241.996）和等长力量（运动前：278 N；运动后 48 小时：232 N；BF10 = 10,289.894）的时间主效应均因损伤性运动方案而发生变化，但条件之间没有差异[所有贝叶斯因子（BF10）]。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
