概括
辅酶Q10 (CoQ10) 补充剂在接受高强度间歇训练 (HIIT) 的老年人中改善了下肢力量和功率. 虽然CoQ10增强了特定的运动,但与安慰剂相比,它没有显著影响整体运动或平衡.
科学领域:
- 老年学和运动科学
- 营养生物化学 营养生物化学
- 运动医学 运动医学
背景情况:
- 衰老与肌肉力量,功率和身体功能的下降有关.
- 高强度间歇训练 (HIIT) 是一种有效的干预措施,可以抵消与年龄相关的功能衰退.
- 辅酶Q10 (CoQ10) 在细胞能量生产中起着至关重要的作用,具有抗氧化特性,可能有利于运动表现和适应.
研究的目的:
- 调查辅酶Q10 (CoQ10) 补充剂在提高老年人对高强度间歇训练 (HIIT) 的身体适应性方面的疗效.
- 为了确定CoQ10是否能改善肌肉力量,功率和身体功能,而不仅仅是HIIT的影响.
- 评估辅酶Q10对各种功能结果的影响,包括力量,平衡,移动性和有氧耐力.
主要方法:
- 进行了一项双盲随机对照试验,对38名65至75岁的成年人进行了随机对照试验.
- 参与者被分配到辅酶Q10或安慰剂组,并完成了为期8周的监督HIIT计划.
- 评估包括下肢力量 (5XSST,30CST),上肢力量 (手握),平衡 (SLS,TUG),运动能力 (25FW) 和有氧耐力 (6MWT) 干预前后.
主要成果:
- 与安慰剂组相比,CoQ10组在30秒5次重复的椅子站立 (5XSST) 和椅子站立 (30CST) 中表现出显著更大的改善 (p <0.05).
- 两组都在握手力,单腿站立 (SLS),6分钟步行测试 (6MWT) 和计时和走 (TUG) 中表现出显著的群体内改善 (p < 0.001).
- 对于手握强度,SLS,6MWT或TUG (p>0.05) 没有发现显著的群体间差异,也没有报告任何不良事件.
结论:
- 辅酶Q10补充剂,当与HIIT相结合时,在老年人中增强了下肢力量和功率的改善.
- 辅酶Q10的好处似乎特定于肌肉功率输出和耐疲劳性,如5XSST和30CST的改善所示.
- 与安慰剂相比,CoQ10在这个人群中没有显示出与安慰剂相比,对一般运动,平衡或握力有显著的额外益处,这表明在运动辅助治疗中具有有针对性的作用.

Pharmacodynamics in Geriatric Patients: Effects of Age
174
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 Metabolism
178
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
205
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
209
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...

The Effect of Aging on Tissues
3.1K
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

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...
