At what age do muscles start to atrophy?

Beijing Deshengmen Hospital of Traditional Chinese Medicine - Yin Shirong - Department of Impotence - Chief Physician - What are the people with a high incidence of muscle atrophy?

Muscle atrophy has little to do with age, and muscle atrophy will only occur if you don't exercise, so if you exercise twice a week, you can basically keep your muscles from atrophying.

Muscles generally begin to atrophy slowly after the age of 40, and then after the age of 50 or 60, the speed of atrophy will gradually accelerate, and then it will become very relaxed.

Thirty years old. At this age, men reach the peak of their strength, and their muscles begin to decline.

As people age, their skeletal muscle mass begins to deteriorate. Your skeletal muscles (also known as lean muscles) are muscles that attach to your bones and are under voluntary control.

As a result of aging, people start to become, well, muscle flabby as they age. You may start to see these changes in your 30s, but most people see the most changes between the ages of 40 and 50.

One study concluded that people between the ages of 20 and 90 lost nearly 50% of their total muscle mass. On average, people lose 30% of their strength between the ages of 50 and 70, and another 30% every decade after that. In general, people lose about 1% of their muscle strength each year after the age of 40.

The following four types of weakened muscles, called atrophy, become more common as we age, and each type responds differently to strength training.

Sedentary: Muscle degeneration is a natural process, but a sedentary lifestyle accelerates it. You can rebuild the muscle mass caused by your sedentary lifestyle – all you have to do is get up from the couch and do some physical activity!

Some sedentary people include bedridden people, astronauts, and people who rarely exercise.

Age-related: Age-related muscle loss is also known as sarcopenia, which means "muscle loss." "Sarcopenia is not an inevitable part of aging; This is due to the loss of about 10 ounces of muscle per year, which has not been replaced by a sedentary lifestyle.

You can restore your muscles through strength training programs.

Drug-related: Certain medications, such as systemic corticosteroids (usually prescribed for people with asthma or inflammatory diseases such as rheumatoid arthritis or lupus), can cause muscle weakness.

Nerve disorders that affect muscles, including polio (poliomyelitis).

Amyotrophic lateral sclerosis (ALS).

Guillain-Barré syndrome (self-limiting demyelinating polyradiculoneuropathy), which can cause short-term muscle weakness or paralysis.

In addition to general skeletal muscle loss, the following changes occur with your age:

In addition to general skeletal muscle loss, the following changes occur with your age:

Muscles take longer to respond to brain signals in their 50s than they did in their 20s. As a normal aging process, you start to lose those muscle fibers that make you move quickly. The transmission of impulses from the brain to the muscles also slows down, so it takes longer to pick up the signal, "Hey!

Move it! "Because of the reduced enzyme activity and protein conversion, your muscles also can't repair themselves as quickly as they used to. ”

The water content of tendons (bands of tissue that connects muscles and bones) decreases with age. This change makes the tissue stiff and less susceptible to stress.

Your heart muscle can't push a lot of blood through your body quickly. As a result, you will tire out faster and take longer to recover.

Generally around the age of 30, individuals begin to lose muscle mass, and as people continue to age, the strength of muscles will become smaller and smaller, the number of stem cells that can repair muscle damage will also decrease, and the ability to repair muscle damage will gradually decline.

There is no specific time for this, and there are many children who suffer from muscle atrophy when they are sick, and as we age, various body functions decline, resulting in muscle atrophy.

There is no age limit for muscle atrophy, if a person who exercises regularly will have a certain amount of atrophy within three years after not exercising, and if he exercises regularly, the atrophy of the muscle will be delayed.

In terms of atrophy, it is a human muscle. Well, there is no degree of development, and then reaching a fish that slowly shrinks and says that the bones are also shrinking. The process of change.
