概括
腹部按压运动最有效地激活下肌肉 (SSC),同时最大限度地减少其他肩部肌肉的补偿. 这种有针对性的方法有助于稳定的肩膀旋转,并可能改善内部旋转损伤的治疗.
科学领域:
- 整形外科 整形外科 整形外科
- 运动医学 运动医学
- 康复 康复 康复 康复
背景情况:
- 治疗炼用于改善 subscapularis 肌肉 (SSC) 的功能和强度.
- 有限的研究存在于选择性激活SSC的练习,同时最大限度地减少周围肌肉补偿.
研究的目的:
- 为了确定选择性下肌肉 (SSC) 激活的最有效的运动.
- 为了比较三种运动的SSC激活和周围肌肉补偿:腹部按压,提升和斜擦拭器.
主要方法:
- 40名健康的参与者在随机排序中进行了腹部按压,提升和倾斜擦拭练习.
- 超声波评估下肌 (SSC) 和下肌 (IS) 肌肉厚度.
- 表面电肌图记录了前腹骨 (AD),大胸骨 (PM) 和后腹骨 (PD) 活动.
- 放射成像评估了瞬间旋转中心 (PICR) 的路径.
主要成果:
- 腹部压力显著降低了脊椎下部 (IS) 厚度,并改变了瞬间旋转中心 (PICR) 的路径 (p < 0.05).
- 在所有测试的运动中,前体 (AD),大胸部 (PM) 和后体 (PD) 的电肌图学活性显著增加 (p < 0.05).
- 腹部压力证明了 subscapularis 肌肉 (SSC) 产生力量的最大能力,具有稳定的旋转中心.
结论:
- 腹部按压运动对于选择性下肌肉 (SSC) 激活是最有效的.
- 这种运动最大限度地减少了周围的旋转肌肉活动,并减少了瞬间旋转中心 (PICR) 的路径.
- 这些发现可以指导临床医生治疗肩部内部旋转损伤.

Muscles of the Shoulder
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
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...
