概括
强力重复增强了年轻成年人的优势手的运动适应,但不是老年人. 根据运动方向和手的支配性,运动任务的适应性有所不同,这表明了定制的训练策略.
科学领域:
- 神经科学是一个神经科学.
- 发动机控制器的控制器
- 人类运动科学科学 人类运动科学
背景情况:
- 敏捷的手动操作整合了感官运动控制和学习.
- 简单的运动任务重复对后续适应动力力扰动的影响尚不清楚.
研究的目的:
- 为了研究基于力和基于运动的运动重复如何影响动态操纵任务中的适应.
- 检查与年龄相关的差异 (年轻人与老年人) 和手占主导地位对运动适应的影响.
主要方法:
- 60名参与者 (30名年轻人,30名老年人) 执行了机器人手举动任务,使用扰动扭矩.
- 在适应之前,参与者进行了重复力 (同位扭矩脉冲) 或运动重复 (手腕旋转).
主要成果:
- 年轻成年人在主导手中重复施加力后表现出更强的适应能力;运动重复没有带来任何好处.
- 老年人没有表现出基于重复类型的显著适应差异.
- 适应的准确性在置和置之间有所不同,置的准确性更高,特别是在年轻人和非主导手中.
结论:
- 强力重复有利于预测性运动控制,但这种效果是由年龄和肢体主导度调节的.
- 研究结果表明,需要根据年龄和手的优势进行定制的运动训练和康复策略.

02:20Longitudinal Research
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...
01:09Changes 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...
