概括

年长的成年人将关节运动量产生转移到部以承受体重,与依赖于脚和膝盖的年轻成年人不同. 这种与年龄相关的步态适应会影响不同步行速度的垂直支力.

科学领域:

生物力学生物力学
老年学是一门学科.
人类运动科学科学人类运动科学

背景情况:

衰老会导致在运动过程中,关节的动量产生从脚和膝盖向部转移.
这种与年龄相关的再分配在推进方面得到了充分的记录,但在承重方面却不太了解.
射手平面时刻比正面平面时刻更受研究,尽管它们对垂直支的贡献很大.

研究的目的:

研究老龄化如何影响前平面和前平面关节时刻对承重的贡献.
为了检查不同步行速度的这些效应.

主要方法:

对年轻人和老年人进行了步行分析,以他们喜欢的速度和更快的速度行走.
使用逐步线性回归来识别预测垂直地面反应力 (VGRF) 的关节时刻.
24名年轻人和17名健康的老年人参与了这项研究.

主要成果:

年轻的成年人主要使用部绑架和膝盖延伸时刻进行前肢承重.
年长的成年人依赖部延伸来承受前肢的重量,而部屈曲来承受后肢的重量.
膝盖延伸时刻的变化影响了年轻人的后肢承重能力,而部延伸时刻则影响了老年人.

结论:

年长和年轻的成年人表现出不同的联合时刻策略,用于在走路时产生垂直支力.
这些差异在前肢和后肢的支方面都很明显,并且随着步行速度而变化.

关键词:

共同的时刻共同的时刻年龄较大的成年人.垂直地面反应力垂直地面反应力步行走路走路承载着重量的轴承.

Changes in the Appendicular Skeleton with Age

Changes in the Appendicular Skeleton with Age

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...
