概括
与鸟狗运动 (BD-ex) 相比,脱落的运动 (HO-ex) 更有效地刺激腰部多 (LM) 和内斜 (IO) 肌肉. 这两种练习都类似地激活横腹肌 (TrA).
科学领域:
- 生物力学和运动生理学
- 肌肉骨超声波成像 肌肉骨超声波成像
背景情况:
- 干部肌肉的激活对于脊柱的稳定性和伤害预防至关重要.
- 了解运动引起的肌肉厚度变化有助于选择用于康复和训练的运动.
研究的目的:
- 在Heel Off (HO-ex) 和Bird Dog (BD-ex) 练习期间测量和比较干部肌肉厚度.
- 为了验证超声波测量,以评估在特定的部伸展炼期间的干部肌肉激活.
主要方法:
- 超声波成像用于测量31名健康男性的腰部多 (LM),直立脊柱 (ES),外斜 (EO),内斜 (IO) 和横腹部 (TrA) 的厚度.
- 肌肉厚度在四个条件下进行了评估:卧底休息,HO-ex,爬行和BD-ex.
- 统计分析 (ANOVA,弗里德曼测试) 确定了不同条件的肌肉厚度的显著差异.
主要成果:
- 腰部多 (LM) 和内斜 (IO) 肌肉在HO-ex期间显示出明显更大的厚度,而不是卧卧.
- 横腹部 (TrA) 激活在HO-ex,爬行和BD-ex期间明显高于躺卧时.
- 勃起脊柱 (ES) 的激活在HO-ex和BD-ex期间是最高的,而不是躺卧和爬行.
结论:
- 脱落脚跟运动 (HO-ex) 似乎比鸟狗运动 (BD-ex) 更有效地刺激多肌和内斜肌.
- 无论是HO-ex还是BD-ex都提供了可比的横腹肌 (TrA) 激活.
- 超声波是量化干部肌肉对不同运动方式的反应的可行工具.

Muscles of the Abdomen

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...

Muscles of the Vertebral Column
1.4K
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
1.4K
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...
