概括
功能有限的老年人保持相似的总能耗 (TEE),尽管身体活动水平较低. 这表明,保持身体成分和增加每次运动代谢成本有助于该人群的能量平衡.
科学领域:
- 老年学是指老年学的学科.
- 人体生理学 人体生理学
- 代谢研究研究 代谢研究
背景情况:
- 老年人的总能耗 (TEE) 是复杂的,受体力活动和身体组成的影响.
- 现有的关于老年人TEE的证据,特别是那些有功能限制的人,仍然不一致.
- 了解能源消耗对于保持老龄人口健康和独立至关重要.
研究的目的:
- 为了比较TEE,身体活动水平 (PAL) 和功能独立和有限的老年人之间的身体组成.
- 调查不同功能能力的老年人中影响能源消耗的因素.
主要方法:
- 对69名居住在社区的日本老年人 (50名独立,19名受限) 的横截面研究.
- 总能耗 (TEE) 用双标记水方法测量.
- 身体活动指数,包括步数,通过三轴加速度计进行评估.
主要成果:
- 在功能独立和有限群体 (男性和女性) 之间,TEE或身体组成没有显著差异.
- 与独立组相比,功能有限组的步数在两性中都明显较低.
- 在受限组的女性中,经过无脂肪体重调整后,较高的TEE与较差的定时起步和起步性能相关.
结论:
- 功能有限的老年人表现出与独立同龄人相似的TEE,尽管身体活动减少.
- 保持身体组成和更高的每次运动代谢成本可能解释了老年人有限的持续TEE.
- 在功能受限的老年女性中,高TEE调整为无脂肪质量,与运动缓慢有关.

The Effect of Aging on Tissues
3.6K
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...

Pharmacodynamics in Geriatric Patients: Effects of Age
367
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
