Exercise and Muscle Performance01:27

Exercise and Muscle Performance

6.2K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Drug Dosing: Geriatric Patients

395
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

The Effect of Aging on Tissues01:19

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...

Bone Disorders01:29

Bone Disorders

8.0K
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

382
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...

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...

Area of Science:

  • Gerontology
  • Exercise Physiology
  • Biomechanics

Background:

  • Aging leads to decreased muscle strength, increasing fall risk and sedentary behavior in older adults.
  • Maintaining lower limb strength is crucial for functional independence and quality of life in the elderly.

Purpose of the Study:

  • To determine if lower limb strengthening exercise improves strength and balance in elderly individuals.
  • To investigate the efficacy of a targeted exercise program for enhancing geriatric mobility.

Main Methods:

  • A randomized controlled trial was conducted over 12 weeks.
  • Fifty participants aged 65-82 were divided into a training group (n=30) and a control group (n=20).
  • The training group performed leg extension and lower curl exercises.

Main Results:

  • The training group showed significant improvements in lower limb strength compared to baseline.
  • Balance function also significantly improved in the training group post-intervention.
  • No significant changes were observed in the control group.

Conclusions:

  • Lower limb strengthening exercises are effective in enhancing muscle strength and balance in older adults.
  • Improved lower limb strength may translate to better balance and reduced fall risk in neurologically intact elderly individuals.
  • This study supports the integration of resistance training into geriatric exercise programs.
