概括

结合单腿支和推高加 (PUP) 运动,可显著提高前 (SA) 肌肉激活. 在PUP练习中增加运动范围可以增强梯形肌的参与,从而更好地稳定脚.

科学领域:

生物力学生物力学
运动生理学运动生理学
运动医学运动医学

背景情况:

推向上加 (PUP) 变化的确切影响,特别是支的基础和头骨外游,对头骨肌肉的激活是不清楚的.
这项研究旨在调查不同延伸-收缩练习期间骨肌的相位特异性电肌图 (EMG) 活动.

研究的目的:

为了比较四个伸缩-收缩练习期间的肌肌肉相位特异性电肌图 (EMG) 活动.
确定支基和运动范围的变化如何影响头骨肌肉激活模式.

主要方法:

26名有 Pilates 经验的健康男性进行了 4 个脚伸缩-收缩练习.
练习是在两种支基础条件下进行的 (四足 vs 单腿) 和两种运动范围 (PUP vs 标准).
记录了六个头骨肌的表面EMG,并将其正常化到最大的自愿同度收缩.

主要成果:

单腿PUP在延伸,同度和收缩阶段表现出最高的前部 (SA) 激活.
标准 (STD) 变异导致了更大的梯形激活,特别是在更大的头巾外游时.
在PUP条件下,上梯形 (UT) 与SA激活比率较低,表明更有利的稳定模式.

结论:

将单脚支持与传统的PUP相结合,在所有练习阶段显著增加了SA的招聘.
在PUP练习期间增加头皮的运动范围可以增强梯形肌的参与.
这些发现提供了有价值的特定阶段的见解,以了解PUP变异如何调节闭链脚稳定,帮助临床医生选择运动.

Muscles of the Shoulder

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.

The anterior thoracic muscles include the serratus anterior, subclavius, and...

Muscles that Move the Arm

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...

Muscles of the Anterior Neck

Muscles of the Anterior Neck

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...
