It can also lead to decreased bone density. In addition, as muscle mass decreases, basal metabolic rate decreases, leading to obesity and visceral obesity.

“Reduce drug use in muscle and chronic diseases and induce cancer cell death”
“Elderly people are prone to dehydration, so it’s important to drink enough water”[현대건강신문] Muscle wasting in the elderly is considered a natural phenomenon, so little attention is paid to it. However, since muscle cells have a very large impact on overall health, it is necessary to focus on maintaining muscle mass.
Professor Lee Byung-hoon, from the Department of Orthopedic Surgery at Gachon University Gil Hospital, explained that ‘sarcopenia’, a marked loss of muscle mass, can occur with age and that muscle mass should be treated as it has a major impact on overall health has the health.
Professor Lee Byung-hoon said, “Age-related muscle wasting has been a medical problem since Irwin Rosenberg first used the term sarcopenia in 1989.) and is classified as a type of disease, not aging.”
Sarcopenia can be divided into primary, which is primary, and secondary, which is secondary. △Primary sarcopenia is associated with aging itself, and △Secondary sarcopenia occurs due to illness, decreased physical activity, malabsorption, or malabsorption.
As you age, your body’s muscle mass decreases. Atrophy and loss of fast-twitch muscle fibers occur, and the number and size of the muscle fibers themselves decrease. Muscle mass decreases naturally due to changes in the microstructure of muscle cells and muscle fibers.
In addition, various bodily functions decrease due to aging, leading to the death of muscle cells due to chronic inflammation, oxidative stress and increased insulin resistance. Therefore, the aging process and the decrease in muscle mass are proportional.
However, age-related loss of muscle mass should not be taken for granted. The loss of muscle mass leads to reduced muscle function, resulting in reduced physical functions such as falling, increasing the risk of injury. It can also lead to decreased bone density. In addition, as muscle mass decreases, basal metabolic rate decreases, leading to obesity and visceral obesity.
Professor Lee said: “It is muscle strength exercise that can prevent sarcopenia. The effect of strength training is not only to change appearance and increase performance, but also to prevent and treat chronic diseases, so it is important for older people with chronic diseases. It’s emphasized,” he said.
He added: “As a result of a survey of elderly chronically ill patients in the famous journal The Lancet, it was also reported that strength training could replace drugs used to treat diseases such as high blood pressure, hyperlipidemia, diabetes and angina pectoris.”
Strength training offers several health benefits. First of all, the effect of improving blood circulation is to be expected.
This prevents vascular diseases such as high blood pressure, heart attack and angina pectoris and reduces the risk of cardiac arrhythmias or sudden cardiac death through smooth coordination of the autonomic nervous system. In addition, diabetes can be controlled by lowering insulin resistance and hyperlipidemia can be treated. Resistance training positively affects longevity genes related to apoptosis, thereby preventing aging.
In particular, it has been confirmed that strength training can prevent cancer. A protein called ‘calprotectin’, which is secreted by muscle, is known to inhibit the growth of cancer cells. A study presented in Leukoc Biology in 1995 showed that exercise also helps prevent cancer, including colon cancer.
The effects of strength training proven so far include △prevention of cardiovascular disease, △treatment of hypertension, △prevention and treatment of cardiac arrhythmia, △prevention of colon cancer, △longevity, △control of diabetes, △treatment of hyperlipidemia, △anticancer effect, △Treating depression; and △Preventing falls.
Adequate hydration is also very important to prevent age-related sarcopenia. Muscles contain a lot of water and act as a water reservoir where water movement can occur at any time. Therefore, if dehydration persists, muscle breakdown can accelerate, so it is important to stick to the recommended daily water intake.
Professor Lee said: “As people age, they become more prone to dehydration due to a decrease in the central function of thirst control and a decrease in kidney function. “Chronic dehydration caused by this leads to a decrease in muscle function and efficiency, so it’s important to consume an adequate amount of water.”
