概括
芭蕾舞者比非舞者走得更快,步伐更长,不论年龄如何. 这项研究揭示了舞者已经增强了下肢机械,但步态稳定性在所有群体中仍然是可比的.
科学领域:
- 生物力学 生物力学
- 人类运动科学科学 人类运动科学
- 舞蹈科学 舞蹈科学 舞蹈科学
背景情况:
- 芭蕾舞训练可以增强腿部的力量,平衡,并减少跌倒的风险.
- 芭蕾舞对步态参数和稳定性的影响尚不清楚.
- 这项研究调查了不同年龄和技能水平的芭蕾舞者中的步态.
研究的目的:
- 分析时空步态参数,动态步态稳定性和芭蕾舞者和非舞者的运动测量.
- 为了比较年轻的职业舞者,年长的休舞者和年龄相匹配的非舞者之间的步态特征.
- 确定芭蕾舞训练如何影响不同年龄组的步态力学和稳定性.
主要方法:
- 60名参与者 (年轻的舞者,年轻的非舞者,年长的舞者,年长的非舞者) 进行了全身运动捕捉和运动分析.
- 主要结果:步行速度. 二次结果:步骤长度,步骤宽度,节奏,动态步行稳定性.
- 三级结果:峰值垂直地面反应力,负载速度,峰值推进力,推进冲动.
主要成果:
- 与非舞者相比,舞者表现出更快的步行速度和更长的步骤长度 (p < 0.05).
- 年轻的参与者比年长的参与者有更窄的步幅和更低的节奏 (p < 0.05).
- 舞者表现出增加的负载率和峰值推进力,表明下肢发电增强 (p < 0.05).
结论:
- 芭蕾舞者,不论年龄,表现出优越的步行速度和步伐长度,这是由于下肢机械的发展.
- 舞者的动力学和动力学差异与他们的训练有关,导致更高的负载率和推进力.
- 尽管生物力学变化,步态稳定性在舞者和非舞者之间保持一致,突出了强大的控制机制.

Pharmacodynamics in Geriatric Patients: Effects of Age
188
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
238
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...
