概括
经济速度 (ES) 随着年龄的增长而放缓,但腿长度正常化显示,炼习惯性不会影响ES. 老年人表现出更大的步态变化,表明与年龄相关的变化,而不是运动,影响行走经济.
科学领域:
- 生物力学 生物力学
- 人类运动科学 人类运动科学
- 老年学是指老年学的学科.
背景情况:
- 步行经济通常是U形的速度,具有最佳的经济速度 (ES).
- 随着年龄的增长,ES通常会下降,但腿的长度和运动习惯对正常化的ES (ES正常化) 的影响还没有得到充分研究.
- 步行适应速度变化的能力涉及步伐长度和步骤频率的协调.
研究的目的:
- 调查衰老和运动习惯对正常化的经济速度 (ES正常化) 的影响.
- 为了量化步态参数时间延迟 (步长和步数频率) 响应动态速度变化.
- 为了比较年轻的久坐不动,年轻的活跃和年长的活跃成年人.
主要方法:
- 参与者:久坐不动的年轻人 (SY),活跃的年轻人 (AY) 和活跃的老年人 (AE).
- 程序:30秒和180秒的时间间隔内侧走势速度变化 (±0.56米/秒).
- 测量:脚步长度和脚步频率的时间延迟,ES和ES的计算正常化.
主要成果:
- 在AE中,ES最慢,其次是SY,然后是AY. 与年轻人相比,AE的ES正常化速度较慢;AY和SY没有差异.
- 与AY相比,AE和SY在180年期间表现出更大的步骤变化.
- 正常化的ES随着年龄的增长而下降,独立于运动习惯. AY证明了降低了步骤可变性.
结论:
- 衰老,而不是运动习惯,减缓了正常化的经济步行速度.
- 年轻人和老年人可能会采用不同的策略来优化步伐长度和步骤频率在速度过渡期间.
- 习惯运动可能会提高年轻人的步行稳定性.

01:19The Effect of Aging on Tissues
2.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

01:30Cognitive Development During Adulthood
129
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

01:30Factors Influencing Heart Rate
2.7K
The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...

01:29Bone Disorders
3.6K
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...
