概括
跳跃期间的动态膝盖 (DKV) 与被指挥的地面接触时间有中等的相关性,但与自然运动无关. 骨对齐对于理解DKV和跳跃性能至关重要.
科学领域:
- 生物力学 生物力学
- 运动医学 运动医学
- 运动学 运动学
背景情况:
- 动态膝盖 (DKV) 经常被认为是受伤风险因素,影响运动训练和康复策略.
- 目前的做法经常强调控制膝盖对齐,尽管有相矛盾的研究结果.
研究的目的:
- 评估跳跃性能指标与导致DKV的解剖因素之间的关系.
- 调查不同提示策略如何影响DKV和跳跃结果.
主要方法:
- 一项涉及35名参与者进行的横截面研究,他们使用不同的DKV提示进行单腿深跳.
- 记录了跳跃性能 (高度,地面接触时间,反应强度指数) 和静态解剖测量.
- 统计分析包括ANOVA,皮尔森相关系数和类内相关系数 (ICC) 以获得可靠性.
主要成果:
- 在基准的DKV跳跃期间,地面接触时间和DKV之间发现了中等的正相关性 (r=.49,p<0.01).
- 在自然跳跃中观察到静态膝盖,Q角和DKV之间的弱正相关性 (r=.37,p<0.01和r=.34,p=0.04).
- 通过骨解剖来规范DKV测量消除了与性能指标的相关性;证实了高inter-rater可靠性 (ICC=.96-.99).
结论:
- 骨的解剖学对齐是跳跃表现中与动态膝盖 (DKV) 一起考虑的重要因素.
- 建议通过静态解剖来使DKV正常化,以便在未来的研究中准确评估其对运动表现和受伤风险的影响.

Knee Joint
1.4K
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...

Bones of the Lower Limb: Femur and Patella
2.1K
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 that Move the Leg
1.3K
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...

Ankle Joint
1.4K
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...

Development of the Limb Synovial Joints
1.3K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

Bones of the Lower Limb: Tibia and Fibula
2.7K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
