概括
在中国成年人中研究了副脊柱肌肉退化,包括横截面 (CSA) 和脂肪透 (FI). 多肌 (MF) 和直立脊柱肌 (ES) 肌肉表现出较早的退化,影响了力量和耐力.
科学领域:
- 老年学是一门学科.
- 肌肉骨成像系统的成像
- 生物力学 生物力学
背景情况:
- 与年龄相关的副脊髓肌肉退化是常见的,但它对中国人的肌肉截面面积 (CSA) 和脂肪透 (FI) 相对强度和耐力的影响尚不清楚.
- 这项研究调查了健康中国人口中衰老,副脊柱肌肉形态学和功能参数之间的关系.
研究的目的:
- 为了检查与年龄相关的CSA和FI类脊柱肌的变化.
- 评估肌肉形态测量与强度和耐力功能测量之间的相关性.
- 为了识别与年龄相关的退化最容易发生的副脊髓肌肉.
主要方法:
- 94名健康的中国志愿者被分为年轻人 (20-39岁),中年人 (40-59岁) 和老年人 (≥60岁) 群体.
- 磁共振成像 (MRI) 量化了psoas (PS),四腰肌 (QL),多肌 (MF) 和直立脊柱肌 (ES) 的CSA和FI.
- 使用Bionix Sim3 Pro和Ito测试,分别评估了最大等距扭矩和耐力.
主要成果:
- 老年人表现出较小的PS和ES CSA,而年轻人则具有较大的QL CSA.
- 在不同年龄组中观察到MF和ES脂肪透的显著差异.
- 随着年龄的增长,最大等距扭矩和耐力下降,尽管并不总是具有统计学意义.
- 副脊椎肌肉CSA与强度正相关,而FI与强度和耐力负相关,特别是在MF和ES肌肉中.
- PS 和 QL 预测的最大等比扭矩; MF 和 PS 预测的耐力时间.
结论:
- 与psoas (PS) 和 quadratus lumborum (QL) 肌肉相比,多肌 (MF) 和直立脊柱 (ES) 肌肉表现出较早的退化.
- MF被确定为主要受功能区域缩影响的副脊髓肌肉,显著影响耐力.
- 腰部脊柱强度与脊肌成像参数相关,QL和PS显示腰部活动的激活更大.

Changes in the Appendicular Skeleton with Age
1.9K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Axial and Appendicular Muscles
1.3K
Skeletal muscles, the key players in our body's movement, can be classified into two groups based on their location and function: axial muscles and appendicular muscles. These classifications reflect the primary roles the muscles play in the body's structure and movement.
Axial Muscles
Axial muscles, situated along the body's midline, are intricately connected to the axial skeleton, which includes the skull, spine, ribs, and sternum. These muscles facilitate facial expressions and...

Vertebral Column: Regions and Curvature
3.5K
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

Introduction to the Skeletal System
5.4K
The skeletal system is the central framework of the body, consisting of different connective tissues: bones, cartilage, tendons, and ligaments.
Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
Cartilage, a semi-rigid connective tissue found in regions such as...

Muscles of the Vertebral Column
1.2K
The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...
