概括

延迟发作的肌肉疼痛 (DOMS) 主要是由深层筋膜损伤引起的,导致胀和硬. 磁共振成像 (MRI) 和剪切波弹性成像 (SWE) 可以有效地评估这些带膜损伤并评估DOMS.

科学领域:

运动医学运动医学
肌肉骨成像系统的成像
连接组织研究连接组织研究

背景情况:

延迟发作的肌肉疼痛 (DOMS) 是异常运动的常见后果.
对于DOMS的主要生成器仍然不清楚,这促使对潜在机制进行进一步调查.

研究的目的:

确定延迟发作的肌肉疼痛 (DOMS) 的主要产生者.

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
