Abstract

Background: Delayed onset muscle soreness (DOMS) is one of the most prevalent musculoskeletal symptoms in individuals engaged in strenuous exercise programs.

Objective: This study investigated the effects of wearable low-intensity continuous ultrasound on muscle biomechanical properties during DOMS.

Methods: Twenty volunteers were distributed into a wearable ultrasound stimulation group (WUG) (n= 10) and medical ultrasound stimulation group (MUG) (n= 10). All subjects performed wrist extensor muscle strength exercises to induce DOMS. At the site of pain, ultrasound of frequency 3 MHz was applied for 1 h or 5 min in each subject of the WUG or MUG, respectively. Before and after ultrasound stimulation, muscle biomechanical properties (tone, stiffness, elasticity, stress relaxation time, and creep) and body temperature were measured, and pain was evaluated.

Results: A significant decrease was found in the tone, stiffness, stress relaxation time, and creep in both groups after ultrasound stimulation (all p< 0.05). A significant decrease in the pain and increases in temperature were observed in both groups (all p< 0.05). No significant differences were observed between the groups in most evaluations.

Conclusion: The stiffness and pain caused by DOMS were alleviated using a wearable ultrasound stimulator. Furthermore, the effects of the wearable ultrasound stimulator were like those of a medical ultrasound stimulator.

可穿戴低强度连续超声波对迟发性肌肉酸痛期间肌肉生物力学特性的影响

背景：延迟性肌肉酸痛（DOMS延迟性肌肉酸痛（DOMS）是剧烈运动者最常见的肌肉骨骼症状之一：本研究调查了可穿戴低强度连续超声波对 DOMS 期间肌肉生物力学特性的影响：20名志愿者被分为可穿戴超声波刺激组（WUG）（10人）和医用超声波刺激组（MUG）（10人）。所有受试者都进行了腕部伸肌力量练习，以诱发 DOMS。在疼痛部位，WUG 组和 MUG 组的每位受试者分别接受频率为 3 MHz 的超声波刺激 1 小时或 5 分钟。在超声波刺激前后，测量了肌肉的生物力学特性（张力、硬度、弹性、应力松弛时间和蠕变）和体温，并对疼痛进行了评估：结果：超声波刺激后，两组肌肉的张力、僵硬度、应力松弛时间和蠕动均明显下降（均为 p<0.05）。两组患者的疼痛明显减轻，体温明显升高（均为 P< 0.05）。在大多数评估中，两组之间未发现明显差异：结论：使用可穿戴超声波刺激器可以缓解 DOMS 引起的僵硬和疼痛。此外，可穿戴超声波刺激器的效果与医用超声波刺激器相似。

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.
