- 老龄化增加了下降风险,身体衰退是其中的一个因素.
- 最小脚宽度 (MTC) 是一个关键的步态参数,与倒和跌倒有关.
- 现有的研究缺乏关于MTC与年龄增长的性别差异的明确性.
研究的目的:
- 在活跃的老年人中调查与性别相关的最低脚清除 (MTC) 的潜在差异.
- 为了确定与年龄相关的步行参数变化,如MTC在老年男性和女性之间有所不同.
主要方法:
- 来自23名女性 (65.5±4.8岁) 和23名男性 (61.9±5.2岁) 在跑步机上行走的动力学数据被收集.

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...

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...

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
