概括
青少年游泳者骨密度较低,IGF-1,和维生素D水平较高. 训练负荷对骨质量有负面影响,但炎症没有介导这种影响,这表明低重力环境的影响.
科学领域:
- 运动医学
- 儿童内分泌学
- 骨生理学
背景情况:
- 青春期的竞技游泳可能会影响骨发育,因为训练负荷,炎症,激素和骨标志物.
- 之前的研究还没有充分探讨青少年游泳者的骨健康.
研究的目的:
- 为了比较青少年游泳者与非运动对照组之间的炎症,免疫, anabolic 和骨标记.
- 在青少年游泳者中调查炎症变量是否介导训练负载和骨密度 (aBMD) 之间的关系.
主要方法:
- 在61名青少年 (30名游泳者,31名非运动者) 的横截面研究中.
- 从感知力和体积计算训练负载;通过DXA评估aBMD.
- 对骨标记物,生长激素 (IGF-1) 和炎症标记物 (IL-6,CRP) 的血液样本进行分析.
主要成果:
- 与非游泳者相比,游泳者表现出较低的aBMD (上肢除外),但较高的,维生素D和IGF-1水平.
- 训练负载直接和负面地与下肢和全身减去头部的aBMD相关.
- 炎症标志物 (IL-6,CRP) 并没有调解训练负载和aBMD之间的关联.
结论:
- 群体之间骨,炎症或免疫标志物没有显著差异,但游泳者有高的IGF-1,和维生素D.
- 与aBMD负相关的训练负载,独立于炎症调解.
- 这些发现支持游泳的低重力环境有助于青少年游泳者的aBMD降低的假设.

01:17Hormones and Bone Tissue
2.9K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:29Bone Disorders
3.9K
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...
