概括
在Y-raise练习中添加同度引力,可以有效地增强健康个体的下形 (LT) 活动. 然而,那些有圆肩姿势 (RSP) 的人可能需要进行结构改进,才能从这种运动修改中受益.
科学领域:
- 生物力学和运动生理学
- 肌肉骨健康 肌肉骨健康
- 纠正运动策略 纠正运动策略
背景情况:
- 圆肩姿势 (RSP) 具有异常的肩膀对齐的特点,通常与胸肌缩短和下形肌 (LT) 虚弱有关.
- 与健康个体相比,RSP中肌肉长度的变化可以在运动期间修改运动模式.
研究的目的:
- 为了比较健康和RSP群体在Y-raise练习期间的上梯形 (UT),LT和前 (SA) 肌肉活动.
- 为了研究在Y-raise练习过程中用弹性带添加同度吸附 (IAD) 对肌肉激活模式的影响.
主要方法:
- 一项涉及32名参与者 (16名健康人,16名RSP) 的横截面研究,根据RSP标准进行分类.
- 表面电肌图 (sEMG) 用于测量UT,LT和SA肌肉活动在Y-raise练习期间与IAD和没有IAD.
主要成果:
- 这两组在Y-raise与IAD期间与单独Y-raise相比,UT和SA活性下降 (p < .025).
- 健康组表现出增加的LT活动与IAD (p <.025),而RSP组显示的LT活动下降 (p <.025).
结论:
- 在Y-raise过程中,同位素引有效地增加了LT活动,并降低了健康个体的UT/SA活动.
- 患有RSP的个体可能需要进行干预,以改善头皮的对齐,然后才能有效地使用IAD进行Y-raise.

Muscles of the Shoulder
8.6K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

Muscles that Move the Arm
4.5K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Assessment of Airway, Skin Color, and Use of Accessory Muscles
1.6K
A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

Muscles of the Anterior Neck
4.4K
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

Axial and Appendicular Muscles
2.6K
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 Thorax

The thorax muscles are central to the body's respiration and provide essential support and movement for the upper body. They are intricately designed to facilitate the complex breathing process while also contributing to the structural integrity and mobility of the chest and upper limbs.
The diaphragm is at the core of thoracic musculature, the primary muscle involved in breathing. This expansive, dome-shaped muscle marks the division between the thoracic and abdominal cavities. It...
