Why don't muscles develop after age 50

Although we can rarely see athletes over the age of 40 in the Olympics, we cannot come across anyone over the age of 50. Have you thought about the reason for this?

The reason for this is that even if people do sports after the age of 50, their muscles do not react to it, that is, they do not develop. Scientists are researching this for people to lead a healthy life after the age of 50.

Even if the old and the young do the same sport, the young people become more muscular, while the old people do not react to this.

So how can our bodies build muscle as we age?

In a healthy young person, when these chemical and mechanical sensory systems detect muscle movement, they open a series of special chemical pathways within the muscle. These pathways, in turn, trigger the production of more protein, which is incorporated into the muscle fibers and causes the muscle to increase in size.

These cellular pathways also activate genes that encode specific proteins in cells that make up the contraction machinery of muscles.

it is a longer term process after a single resistance training session where it is turned on and off for several hours

The overall effect of these many exercise-induced changes is to cause your muscles to grow.
How do old muscles change?

While the basic biology of all people, young or old, is more or less the same, there is something behind the lack of seniors in professional sports. So what changes in a person's muscles as they get older?

What my colleagues and I found in our research are many processes in young muscles that a little exercise triggers muscle growth.

By comparison, older people's muscles are much weaker, for a given amount of exercise

These changes begin to appear when a person turns 50 and become more pronounced as time goes on.

In a recent study, we wanted to see if changes in signaling were accompanied by any changes in which genes ? and how many ? respond to exercise.

Using a technique that allows us to measure changes in thousands of genes in response to resistance exercise, we found that there were changes in expression of more than 150 genes when young men exercised.

When we look at older men, only 42 genes show changes in expression. This difference in gene expression seems to explain, at least in part, the more visible variation between how younger and older people respond to strength training.
Staying in shape as you age

When you put together all of the various molecular differences in how older adults respond to strength training, the result is that older people don't gain muscle mass as well as younger ones.

But this fact should not deter seniors from exercising. If anything, it should encourage you to exercise more as you get older.

remains one of the most important activities older adults can do for their health. The work that my colleagues and I have done clearly demonstrates that although responses to education decline with age, it is by no means reduced to zero.

We have shown that older adults with movement problems who participate in a regular program of aerobic and resistance exercise can reduce their risk of injury by about 20 percent.

We found a similar 20 percent reduction in injury risk in people who were already physically weak if they followed the same training program.

While younger people can get stronger and build bigger muscles much faster than their older counterparts, older people still reap incredibly valuable health benefits from exercise, including better strength, physical function and less injury. So the next time you sweat during a training session, remember that you are developing muscle strength, which is vital for maintaining mobility and health throughout a long life.
