概括
超重的个体通过改变跨越障碍物时的脚位来调整他们的步态,增加障碍物前后的距离. 这项研究没有发现时空步行参数或脚的距离有显著差异,这表明没有增加脚的风险.
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
- 肥胖问题研究研究
背景情况:
- 超重可以使障碍物谈判复杂化,可能会影响脚距离,增加接触风险.
- 了解超重个体的步态调整对于预防跌倒的策略至关重要.
研究的目的:
- 为了比较跨越障碍物时的障碍清除和时空步态参数,在正常体重的年轻人中比较超重.
- 为了研究身体质量指数如何影响跨越障碍物时的步态适应.
主要方法:
- 28名正常体重 (BMI 18.5-25 kg/m2) 和15名超重体重 (BMI 25-30 kg/m2) 的成年人以他们喜欢的速度走路并跨越障碍物.
- 在接近和穿越阶段测量了时空步态参数,脚位距离和脚距离.
主要成果:
- 没有观察到在接近或交叉阶段的参数,也没有在前/后脚的清除群体之间的显著差异.
- 超重的个体显著增加了障碍物前的前脚位置距离 (+7厘米) 和障碍物后的后脚位置距离 (+8.1厘米).
结论:
- 与正常体重的个体相比,超重的个体在跨越障碍物时表现出改变的脚位策略.
- 尽管脚部位置发生了变化,但步态参数和脚宽度仍然相似,这表明超重参与者的脚风险没有增加.

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...
01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
