- 肌肉骨超声波 肌肉骨超声波
背景情况:
- 上肢软组织度失衡与网球相关的肩膀和肘部伤害有关.
- 超声波剪切波弹性学提供精确,可量化的肌肉硬度测量.
- 这项研究旨在比较网球运动员和非运动员之间的肌和肌肉性.
研究的目的:
- 为了研究健康的网球运动员和非运动员之间的胸部大,胸部小和常见的手腕延伸硬度的差异.
- 建立休网球运动员软组织刚性的基线数据.
- 为网球引起的肌肉骨损伤提供潜在的康复策略的信息.
主要方法:
- 采用了横截面研究设计.
- 两维剪波弹性学超声波测量了大胸部,小胸部和主导的常见手腕延伸肌中的剪波模量 (kPa).
- 独立的t测试和多变量一般线性模型分析了群体差异,并使用类内相关系数 (ICC) 评估可靠性.
主要成果:
- 其中包括26名参与者 (13名网球运动员,13名非运动员).
- 对于常见的手腕延伸器 (ICC> .94) 和胸部肌肉 (ICC> .78) 证实了优异的日内内可靠性.
- 与非网球运动员相比,网球运动员表现出明显更高的常见手腕延伸硬度 (平均差异=114.8kPa,P=0.039);胸部肌肉硬度差异没有显著性 (P>0.214).
结论:
- 与非玩家相比,休网球运动员表现出较高的常见手腕延伸肌硬度.

Relaxation of Skeletal Muscles
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open....

Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Disorders of the Skeletal Muscle
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
