概括
老龄化增加重心 (COG) 摆动速度在老年人中,表明更大的不稳定性. 这种COG的不稳定性可能会影响运动的开始,如在不稳定的个体中减少步伐长度.
科学领域:
- 老年学是指老年学的学科.
- 生物力学 生物力学
- 人类运动科学科学 人类运动科学
背景情况:
- 以前的研究表明,与年轻人相比,老年人的重心 (COG) 不稳定性更大.
- 目前尚不清楚老化本身是否是COG不稳定的直接原因.
- 这项纵向研究调查了COG摇摆和步态动力学的与年龄相关的变化.
研究的目的:
- 在十年内纵向评估中年和老年人中重心 (COG) 摆动和步态动力学的变化.
- 为了确定衰老是否直接导致COG不稳定.
- 为了确定COG不稳定性和步态参数之间的潜在联系.
主要方法:
- 一项纵向研究涉及198名健康的中年人和老年人,追踪了十年.
- 稳定计和运动测试,包括高度调整的最大步伐长度 (HMSL) 和10米步行测试 (10MWT),每隔10年进行一次.
- 参与者被分为一个不稳定的组 (10年后平均速度>3厘米/秒) 和一个稳定的组进行比较分析.
主要成果:
- 在10年内观察到平均速度 (开眼) 的显著增加 (1.53 ± 0.42厘米到1.86 ± 0.67厘米,p < 0.001).
- 没有发现摇摆面积的显著变化,但在前后重心 (Y中心) 发生了显著的负转移 (p < 0.001).
- 与稳定组 (0.72,p = 0.019) 相比,不稳定组在十年后显示出明显较小的HMSL (0.64).
结论:
- 十年COG摇摆变化的特点是平均速度增加,而摇摆面积没有显著变化.
- 在不稳定组中减少的HMSL表明COG不稳定性会影响运动的开始.
- 老龄化似乎有助于增加COG摇摆速度和步行启动期间潜在的不稳定性.

12.0K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

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...
