概括
骨功能障碍 (SD) 改变了青少年游泳者的早期臂部升高,影响了游泳中骨上升旋转和内部旋转. 这可能会增加肩膀撞击的风险.
科学领域:
- 运动医学 运动医学
- 生物力学 生物力学
- 整形外科 整形外科 整形外科
背景情况:
- 骨功能障碍 (SD) 的特点是骨肌肉活动异常和手臂升高期间的动力学.
- 了解SD对游泳生物力学的影响对于预防青少年运动员受伤至关重要.
研究的目的:
- 为了研究SD对骨肌肉活动和游泳中风运动期间动力学的影响.
- 为了比较患有SD和没有SD的游泳者之间的骨肌肉激活和运动模式.
主要方法:
- 17名青少年游泳者被分为SD (n=8) 和对照 (n=9) 组.
- 在游泳台上进行泳动时,记录了骨肌肉活动 (梯形肌,前肌) 和动力学 (向上旋转,内部旋转,后侧倾斜,手臂升高).
- 数据被时间规范化,并使用统计参数映射 (SPM) 未配对的t测试进行分析.
主要成果:
- 患有SD的青少年游泳者在游泳中风阶段的初始0-10% (p=0.041) 显著减少了头骨上向旋转.
- 在SD组中,在中风阶段的前0-15%观察到增加的头骨内旋转 (p=0.033).
- 两组之间在头巾后侧倾斜或肌肉活动方面没有发现显著差异.
结论:
- 在青少年游泳者中,SD显著改变了头骨动力学,特别是向上旋转和内部旋转,在游泳冲动的初始阶段.
- 这些动力学变化可能会使SD的游泳者更容易患上亚体冲刺综合征的风险.
- 针对头肌功能和运动学的有针对性的干预措施可能对患有SD的游泳者有益.

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Muscles of the Shoulder
9.4K
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
5.5K
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...
