Sarcopenia

Successful maintenance activity remains a challenging area of research because of the multifactorial contributions of age, nutrition, hormones, medical comorbidities, and activity level to changes in muscle over time. There is a spectrum of changes in aging muscle, some of which are normal and some of which are not. Sarcopenia has been more quantitatively defined as relative muscle mass less than 2 standard deviations below a sex-matched control group aged 18 to 40 years, but the lack of a clear definition has resulted in a wide range of prevalence from 8% to 40%. The 2010 European Working Group on Sarcopenia in Older People defined 3 stages of this process: presarcopenia is simply loss of muscle mass, sarcopenia is muscle loss that occurs…

I recently hit a milestone in my life; I hit the half-century mark. I started getting solicitations for AARP and other senior related material. Really me, I thought a senior citizen no way but the reality is I am getting older and even though I take care of myself I still need to be aware and prepared for the potential changes within my body. One of the largest long-term threats to our ability to remain healthy and function independently while aging is a steady loss of lean muscle mass…

Sarcopenia is a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength with a risk of adverse outcomes such as physical disability, poor quality of life and death (Tanimoto et al., 2013). Muscle accounts for 60% of the body’s protein stores. Muscle mass decrease is directly responsible for functional impairment with loss of strength, increased likelihood of falls, and loss of autonomy, respiratory function is also impaired with a reduced vital capacity…

AIM: Sarcopenia has been defined as an involuntary loss of skeletal muscle mass and strength and/or function. The presence of sarcopenia in patients with Parkinson’s disease (PD) may have prognostic effects and may be mistaken for poor therapeutic control of PD. We aimed to evaluate sarcopenia in patients with PD. METHODS: One hundred non-demented PD patients, and 95 healthy subjects were included in the study. Avarage-Muscle mass, weight, bone mass, fat mass, basal metabolism rate (BMR), body…

Sarcopenia and Protein Intake: Is the RDA Adequate? Introduction Sarcopenia is an age related condition which is characterized by a loss of skeletal muscle and function.1 The decline in skeletal muscle begins in the fourth decade of life and by age 80 a 30% reduction in muscle mass can be seen, with even greater losses in functional strength.1 Significant decrements in muscle mass and strength increase the risk of morbidity and mortality in the aged.1 The prevalence of sarcopenia in 60 year…

Sarcopenia is defined by loss of skeletal muscle mass and function this happens when a person ages . Sarcopenia includes loss of decrease in muscle and quality, loss of motor neurons that allows the muscles to contract, loss of muscle strength . Lean body mass decreases in people between the ages of 30 to 70. Krinke states “lean body mass decreases around 2 to 3% per decade after the age of 30, including loss of muscle beginning around age 40, even when persons weight is stable. During this…

Over the course of aging, the main physical change involves sarcopenia; it is the decrease in muscle size and fiber number, which affects an individual’s aerobic capacity and strength as a result of the change in muscle composition. With decreased aerobic capacity and strength in muscles, this causes detrimental effects on performing any activities or tasks that consist of running, walking, moving or carrying objects, and activities required for daily living. Muscles consist of two different…

while exercising. The second mechanism is Hormonal Factors, many specific hormones are regulators of muscle protein production such as growth hormone (GH), testosterone and insulinlike growth factor 1 (IGF1). Anabolic hormones such as testosterone and growth hormone (GH) are reduced with age, the removal of them from the body can result in muscle atrophy and sarcopenia. Studies have found there is a 3% decline each year in testosterone levels for men, at this same time, there is a loss…

releasing the feel good endorphins in the brain and therefore helping people who are depressed. Exercise in general is great for depression, but weight lifting has more of an added advantage because of its ability to increase strength and stability in the body. Weight lifting is helpful in the elderly because it helps improve their physical strength. It is common knowledge that people who start weight lifting and doing resistance workouts get stronger. It can only be concluded that the elderly…

Intervention 1. Walking for 30 minutes at least 4-5 times each week. Intervention 2. Will join a local fitness center or attend exercise classes at the local senior citizen center. Intervention 3. Increase daily activity by making changes in behaviors such as taking stairs instead of elevator, parking away from buildings to encourage walking and performing yard and house work. Rationale. With the ageing process muscle mass is lost and this is known as sarcopenia or age related muscle wasting.…
