Can you increase muscle mass at any age? Why strength training is important as you get older｜dear_canna8943

“Is it difficult to build muscle at my age?”

Have you ever thought that?

Muscle mass gradually decreases with age.

It is known that, especially after the age of 30, muscle mass and strength will gradually decline if nothing is done.

However, what is important here is that

it does not mean that “you cannot build muscle as you get older.”

In fact, studies on the elderly have confirmed that strength training can improve muscle size and strength.

So, why is strength training important as you age?

Muscle decreases with age

When you are young, you can maintain a certain amount of muscle in your daily life without being particularly conscious of it.

However, as you age, the process of building muscle gradually declines, and combined with a lack of exercise and reduced food intake, it becomes easier for muscle mass to decrease.

You may see figures like “it decreases by 1% every year after age 30,” but actual changes vary by individual and are not determined solely by age.

That is precisely why

it is important not to give up by saying “it’s just my age,” but to minimize the decline as much as possible.

You can build muscle at any age

This is the point I want to emphasize most.

Muscle is not just for young people.

It is known that even as you age, you can increase your strength and muscle size by continuing appropriate strength training.

Studies on people over 75 have also confirmed that strength training improves muscle strength and size.

Of course, it may not change at the same speed as when you were young.

However, it is never “too late” because of your age.

Fast-twitch and slow-twitch muscles: what is the difference?

Muscles are broadly divided into fast-twitch (muscles that exert force quickly) and slow-twitch (muscles that are good at sustaining force for a long time).

For example, when walking for a long time or running slowly, slow-twitch muscles with excellent endurance are active.

On the other hand,

• Recovering your balance when you stumble
• Climbing stairs quickly
• Standing up from a chair
• Moving suddenly

In situations like these, the ability to exert force quickly becomes important.

And it is this ability to exert force quickly that tends to decline particularly with age.

Stimulating muscle fibers, including fast-twitch ones, through strength training is important for maintaining strength and physical function as you age. In fact, it has been confirmed that even in the elderly, both fast-twitch and slow-twitch muscle fibers can grow through strength training.

Strength is also needed for a “body that doesn’t fall”

As you age, it is not just about having “less muscle”; the ability to move your body quickly also becomes important.

For example, when you trip while walking.

Slow movements alone may not be enough.

What is needed in such moments is the ability to exert force instantaneously.

Therefore, even for exercise aimed at maintaining health, it makes sense to incorporate strength training like squats, rather than just walking.

Of course, the premise is to do it safely according to your age and physical strength.

Strength training also stimulates bones

The benefits of strength training are not limited to muscles.

When muscles exert force, mechanical stress is also applied to the bones.

Therefore, strength training can help not only maintain muscle but also suppress the decline in bone density.

In fact, studies on the elderly have confirmed that strength training improves muscle strength and has a positive effect on bone density in areas like the hip joint.

In other words,

protecting your muscles also leads to protecting your ability to move.

It is not just about “increasing”

I have been talking about “increasing muscle” up to this point, but not everyone needs to build large muscles.

If your goal is to maintain health,

not losing the muscle you currently have as much as possible

is also a worthy goal.

And for those who have not exercised before, gradually building strength is also very meaningful.

Instead of giving up because of your age, start with the exercises you can do at that time.

Even that alone will be an important accumulation for your future body.

Summary

Muscle tends to decrease with age.

However,

it does not mean that “you cannot build muscle as you get older.”

By continuing strength training, you can expect improvements in strength and muscle mass regardless of age.

In particular, it is important for future physical function to maintain not only daily movements like walking and standing, but also the ability to exert force quickly.

Furthermore, strength training stimulates not only muscles but also bones.

Rather than “getting your body back to how it was when you were young,”

protect the muscles you have now and ensure you can continue to move your body in the future.

I hope we can continue strength training without overdoing it with that mindset.
