- 运动生理学 运动生理学
背景情况:
- 最佳的肩膀和干神经肌肉协调对于上空运动员的表现和伤害预防至关重要.
- 孤立的肩部旋转测试可能无法完全评估功能性投位置所需的复杂肌肉协同作用.
- 运动型肩部 (ASH) 测试越来越多地使用,但其与传统孤立评估的关系研究不足.
研究的目的:
- 为了检查在同度肩部旋转测试和多关节运动肩部 (ASH) 测试中的肌肉活动模式之间的关系,在空投运动员中.
- 为了比较孤立和综合肩部评估方法之间的神经肌肉激活差异.
主要方法:
- 表面电肌图 (sEMG) 分析了17名男子国家棒球队运动员的9个肩膀和干部肌肉的肌肉激活.
- 在孤立的内部/外部旋转和主导手臂的三个ASH测试位置 (ASH I,ASH Y,ASH T) 中,在最大自愿收缩期间测量了肌肉激活.
- 规范化肌肉激活值被用于相关性分析.
主要成果:
- 在内部/外部旋转测试和ASH测试位置 (p <0.05) 之间观察到肌肉活动的显著差异.
- 在旋转测试中,脊柱内骨,脊柱上骨和形上骨表现出更高的激活,而在ASH测试中,外侧斜骨和大胸骨表现出更高的激活.

Muscles of the Shoulder
8.8K
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.

Muscle Coordination and Action
3.0K
Muscle coordination is a complex and finely tuned process essential for smooth and purposeful movements like flexion, extension, adduction, abduction, and rotation. The human body orchestrates the actions of various muscles working in concert, each with a specific role. Four functional types describe how muscles work together: agonist, antagonist, synergist, and fixator.

Muscles that Move the Arm
4.6K
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...

Isotonic and Isometric Muscle Contractions
6.6K
Two primary types of muscle contractions are isotonic and isometric, each serving unique functions and involving distinct mechanisms. Both isotonic and isometric contractions are integral to the body's complex system of movement and stability. Isotonic exercises contribute significantly to functional strength and movement, while isometric contractions are crucial for maintaining posture and joint stability.
