概括
脚的背部屈曲显著提高了部绑架器的强度和肌肉活动. 这一发现表明,在横卧部绑架练习期间将脚置于背部屈曲的位置,可以改善部绑架器软弱的康复结果.
科学领域:
- 生物力学 生物力学
- 康复科学 康复科学 康复科学
- 运动生理学 运动生理学
背景情况:
- 部绑架器的弱点在腰部疼痛和骨关节炎等疾病中很普遍,影响骨盆的稳定性和功能.
- 横卧部绑架练习在康复中很常见,但脚位置对肌肉激活的影响尚不清楚.
研究的目的:
- 为了研究不同的脚关节角度和激活状态如何影响关节绑架器的强度和肌肉活动.
- 为了确定最佳的脚定位,在运动期间最大限度地增加部绑架器的参与.
主要方法:
- 15名健康的男性进行了横卧关节绑架,脚处于中性状态,背部和脚下.
- 表面电肌扫描 (EMG) 测量了张带近侧 (TFL) 和部中部 (G-med) 的活动.
- 在三个脚激活状态中评估了部绑架强度:没有激活,最大背部屈曲和最大脚下屈曲.
主要成果:
- 在脚角度和激活状态之间发现了显著的相互作用效应.
- 与中性和脚部flexion (p < 0.001) 相比,背部flexion 的部移动强度显著更高.
- 张张侧 (TFL) 和关节 (G-med) 的EMG活动在背部曲过程中达到峰值,特别是最大背部曲.
结论:
- 脚的背部屈曲增强了部引器的强度和肌肉活动,可能是通过增加带张力和改善四肢对齐.
- 这表明背部屈曲是针对部绑架器软弱的康复策略的有益修改.
- 需要进一步的干预研究来证实这种负载调节训练恢复方法.

Ankle Joint
1.9K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Muscles that Move the Thigh
1.5K
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
2.9K
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...

Bones of the Lower Limb: Femur and Patella
3.0K
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...

Muscles of the Leg that Move the Foot and Toes
2.5K
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....

Knee Joint
2.3K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...
