概括
部绑架器的弱点会影响部功能. gluteus maximus (Gmax) 是一个关键的部绑架器,在被削弱时显著减少绑架力. 张张面膜近距离 (TFL) 的影响最小.
科学领域:
- 生物力学 生物力学
- 人体生理学 人体生理学
- 肌肉骨研究 研究
背景情况:
- 部绑架肌肉对于保持骨盆稳定性和下肢功能在行走和跑步等活动中至关重要.
- 了解每个部绑架肌肉对整体绑架力的具体贡献,对于诊断和治疗部软弱至关重要.
研究的目的:
- 为了研究试验诱导的软弱的张张 (TFL),部中部和最小 (Gmed/min) 和部最大 (Gmax) 在部绑架力上的个人影响.
- 为了确定这些肌肉作为不同部位置的部绑架者的相对重要性.
主要方法:
- 十名参与者经历了针对TFL,Gmed/min和Gmax肌肉的连续神经阻塞.
- 部绑架力是在部处于三种角平面的侧向部位置测量的:30°曲,中性和30°延伸.
主要成果:
- TFL的弱点导致绑架力略有减少 (15%),特别是30°部曲,这表明作为主要绑架器的贡献有限.
- 诱导的Gmax弱度显著降低了关节绑架力,特别是在曲 (43%-56%的减少取决于部位置),突出了其实质性的作用.
- 在所有测试的部位置上,当其功能受损时,Gmed/min始终显示出绑架力显著减少.
结论:
- 关节最大 (Gmax) 是一个非常重要的部绑架器,其弱点显著影响绑架强度,特别是在部曲.
- 张张面膜近距离 (TFL) 在部绑架力产生中起到较小的作用,其贡献取决于位置,不如Gmax那么重要.
- 针对性地加强关节最大和关节中等/最小是解决关节绑架弱点和改善整体关节功能的关键.

Muscles that Move the Thigh
767
The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar...

Muscles that Move the Leg
1.4K
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

Muscles of the Leg that Move the Foot and Toes
1.2K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....

Muscles of the Abdomen
1.0K
The abdominal wall encircles the abdominal cavity, providing flexible protection and shielding the internal organs from harm. It is bordered at the top by the xiphoid process and costal margins, at the back by the vertebral column, and at the bottom by the pelvic bones and inguinal ligament. The abdominal wall is divided into two regions — the anterolateral and posterior regions.
Anterolateral Region
The anterolateral region comprises five paired muscles classified into the lateral and...

Bones of the Lower Limb: Femur and Patella
2.2K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Arteries of Lower Limbs
1.1K
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...
