概括
青少年运动员具有较高的异动力学肌肉强度,特别是膝盖延伸峰值扭矩,显示出更好的骨矿物质密度. 这凸显了力量训练对年轻运动员骨健康的重要性.
科学领域:
- 运动医学 运动医学
- 生物力学 生物力学
- 骨生理学 骨生理学
背景情况:
- 肌肉收缩产生了对骨适应至关重要的力量,增强了强度和抵抗力.
- 了解肌肉功能与骨健康之间的联系对运动员至关重要.
研究的目的:
- 系统地审查和综合关于青少年运动员中异动力肌肉强度和骨健康之间的联系的证据.
- 分析各种骨部位的峰值扭矩和骨矿物质密度之间的关系.
主要方法:
- 在多个数据库中进行了全面的文献搜索 (MEDLINE/PubMed,科学网,Scopus,Embase,SciELO,SPORTDiscus).
- 六项研究符合纳入标准,重点关注膝盖延伸/屈曲峰值扭矩和骨矿物质密度.
- 分析了数据,以确定肌肉强度和骨参数之间的关系的强度和重要性.
主要成果:
- 在多个部位 (包括全身,脊柱和上肢) 发现峰值扭矩和骨矿物质密度之间存在显著的积极关联.
- 膝盖延伸峰值扭矩与骨矿物质密度的关系比膝盖屈曲峰值扭矩更强,更频繁.
- 虽然在不同地点观察到关联,但这种关系的强度各不相同,上肢骨矿物质密度显示了显著关系的最高百分比.
结论:
- 异位动力肌肉强度,特别是峰值扭矩,与两性青少年运动员的骨矿物质密度有关.
- 在这个人群中,膝盖伸展强度似乎是骨矿物质密度的更重要的预测因素,而不是膝盖屈曲强度.

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

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...
