概括
举重运动增加了膝关节关节炎的风险,特别是在下肢肌肉质量较低的个体中. 不具有重量活动似乎不会带来同样的风险.
科学领域:
- 整形外科 整形外科 整形外科
- 流行病学 流行病学
- 运动医学 运动医学
背景情况:
- 总体身体活动水平与骨关节炎风险无关.
- 不同体力活动对膝关节骨关节炎发展的具体影响尚不清楚.
研究的目的:
- 调查举重的娱乐性体育活动与患膝关节关节炎新病例的风险之间的关联.
主要方法:
- 一项前性队列研究,利用来自鹿特丹研究 (1996-2009) 的数据.
- 包括5003名45岁以上的参与者,基线和后续膝盖X射线,不包括那些有先前存在的关节炎的人.
- 通过问卷评估娱乐性体力活动类型 (举重与非举重) 并使用逻辑回归分析发生的膝关节骨关节炎,按下肢肌肉质量指数 (LMI) 分层.
主要成果:
- 参与较高的举重活动与发生膝关节骨关节炎的风险增加相关 (OR,1.22;95% CI,1.10-1.35).
- 非举重活动与膝关节骨关节炎风险没有显著关联 (OR,1.04;95% CI,0.95-1.15).
- 举重活动和骨关节炎之间的关联仅在下肢肌肉质量指数 (OR,1.53;95% CI,1.15-2.04) 最低三位数内的参与者中具有意义.
结论:
- 举重的娱乐活动与患膝关节关节炎的风险更高有关,特别是在下肢肌肉较少的人群中.

Bones of the Lower Limb: Femur and Patella
2.4K
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...

Bones of the Lower Limb: Tibia and Fibula
3.2K
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...

Bone Disorders
3.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Muscles that Move the Leg
1.7K
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...

Knee Joint
1.7K
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...
