概括
低腰痛 (LBP) 的划船员在最大努力划船时,与无疼痛的划船员相比,胸部勃起脊柱,腰部勃起脊柱和斜背肌肉活动增加. 这表明LBP的手过度参与背部肌肉.
科学领域:
- 运动医学 运动医学
- 生物力学 生物力学
- 运动生理学 运动生理学
背景情况:
- 低背部疼痛 (LBP) 在划船者中很普遍.
- 在划船期间,干肌的激活模式在带有和没有LBP的划船者之间可能有所不同.
- 了解这些差异对于伤害预防和康复策略至关重要.
研究的目的:
- 为了比较体肌肉活动在最大努力划船与没有LBP的划船者之间划船.
- 为了研究特定的肌肉群体,包括胸部直立脊柱 (TES),腰部直立脊柱 (LES),脊椎直立脊柱 (LD),直肠腹部 (RA) 和外斜 (EO).
主要方法:
- 十名患有下腰痛的划船员和12名无痛的划船员完成了500米最大努力划船试验.
- 无线表面电肌图 (EMG) 记录了干部肌肉活动.
- 在整个中风周期中分析了EMG数据,并将其正常化为最大的自愿同度收缩.
主要成果:
- 在TES和LES活动中观察到显著的相互作用.
- 患有LBP的划船员在早期中风周期 (10-30%) 中表现出显著更高的TES活动,并在最开始 (0-10%) 中表现出更高的LES活动.
- 在LBP组中发现整体LD活性较高,而RA和EO活性没有显著差异.
结论:
- 患有LBP的划船员在最大努力划船时表现出TES,LES和LD肌肉过度激活.
- 这些发现突显了手经历腰部疼痛时神经肌肉控制策略的改变.
- 这种过度的背部肌肉活动可能会导致LBP在这个人群中的恶化或持续.

Muscles of the Vertebral Column
1.5K
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...

Axial and Appendicular Muscles
1.5K
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...

Muscles of the Abdomen
1.7K
The abdominal wall encircles the abdominal cavity, providing flexible protection and shielding the internal organs from harm. It is bordered at the top by the xiphoid process and costal margins, at the back by the vertebral column, and at the bottom by the pelvic bones and inguinal ligament. The abdominal wall is divided into two regions — the anterolateral and posterior regions.
Anterolateral Region
The anterolateral region comprises five paired muscles classified into the lateral and...
