概括
路上骑自行车的人的身体脂肪和BMI比不训练的人低,骨密度和肌肉强度相似. 骑自行车的人的骨健康与身体组成有关,而不是直接与膝盖延伸肌肉强度有关.
科学领域:
- 运动科学 运动科学 运动科学
- 运动生理学 运动生理学
- 骨健康 骨健康 骨健康
背景情况:
- 研究运动员的骨健康,身体组成和肌肉功能之间的相互作用对于表现和伤害预防至关重要.
- 与久坐不动的人相比,路上骑自行车的人表现出明显的生理适应性,这需要详细检查他们的肌肉骨系统.
研究的目的:
- 为了比较道路骑自行车者与未经训练的对照者的骨和身体组成参数.
- 检查这些参数与膝盖延伸肌肉最大自愿收缩力 (MVC) 之间的关系.
主要方法:
- 双能X射线吸收计 (DXA) 用于评估骨矿物质含量 (BMC),骨矿物质密度 (BMD) 和身体成分.
- 用12名男性公路骑行者和12名年龄相匹配的对照人群使用定制动力表测量KE肌肉的同位MVC力.
主要成果:
- 在骑自行车者和对照者之间没有观察到BMC,BMD,瘦身量或KE MVC力度的显著差异.
- 与骑自行车的人相比,对照人群的体重指数 (BMI) 和全身和腿部脂肪质量较高 (P<0.01).
- 在骑自行车的人中,BMC与身体质量和肌肉质量 (P<0.001) 有积极的相关性,而BMD与肌肉质量 (P<0.05) 有相关性. KE肌肉MVC力与骑自行车者的骨参数没有相关性.
结论:
- 定期骑自行车训练与降低BMI和体脂质量有关.
- 尽管骨和肌肉强度相似,但骑自行车的人表现出更健康的身体组成.
- 在公路自行车运动员中,骨参数与体重和肌肉质量有关,但与同位数膝盖延伸器强度没有直接关系.

Bones of the Lower Limb: Femur and Patella
2.6K
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
3.8K
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
3.7K
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...
