Sarcopenia, which is the loss of muscle mass due to aging, often occurs because of lower levels of growth hormones, such as testosterone, and difficulties in absorbing the key nutrients we need, says Chen. (This article on your aging muscles will terrify you, but it could change your life.)
Generally, by the age of 30+, men and women can begin to lose muscle mass – even though Is more common in men – but the process will accelerate from 75 years old. However, if you have genes that expose you to a higher risk of muscle loss, this process will begin even sooner.

There are certain genes that can tell you if you have a higher probability of being an athlete of power, with greater muscle contraction capacity and function that allows you to excel in a rigorous sport, says Chen. It's especially related to young athletes, and more research is needed to make a bigger demand for athletes of all ages, she notes.

says, everyone has different genetic components that can affect muscle function. "There are genes that lean if, for example, you naturally have a lower volume of subcutaneous fat and you have gained more skeletal muscle volume after resistance training," says Chen. (The subcutaneous fat is the layer that lies just under the skin on the thighs and buttocks.This type is less dangerous than visceral fat, which is the abdominal fat surrounding the organs.) Specifically, the BMP2 genes are associated with building and muscle retention. she says. What all this means is that some people naturally have less fat and more muscle mass than others, and that they will lose muscle more slowly than those who have not. not this genetic trend, even if they get older.

In fact, a 2015 genetic study involving 38,292 people from 20 different groups of European ancestry, discovered that certain genetic variations, which they identified 21, seemed to influence total lean mass and muscle loss, says Chen. "So, there are places in our genetic sequence that indicate if we could have a better ability to have lean body mass, whether we can gain more lean mass after resistance training or not," she says.
is necessary. "We've come so far, absolutely, but there's still a lot of work to be done, and we need to find more and more data on how different gene variations work together to help reduce body weight." ". 19659002] PLUS: Exactly how fast you lose muscle when you stop exercising
What can I do about it?
You may want to start by learning more about your genes. Take a saliva sample on the cheek using a home DNA kit (we searched for the most popular kits for you), and then send it for review. Depending on which kit you choose, the answers can tell you if your genes allow you to gain more body mass with exercise. If they do, you can capitalize on that and build more muscle early to prevent sarcopenia, Chen says. Work on resistance training (try these 10 best strength training moves for women over 50) and use your athletic genes to your advantage rather than pulling them down.
What if you do not have these genes? Do not say, "Oh, I see my genes, now I can not do anything about it." Your genetics is a model of how your body is, but your lifestyle will also help determine what it is. can and can not do it.People who are not genetically capable of creating body mass with resistance training, or who are predisposed to having less lean body mass, are at a disadvantage, so they should really be focusing on maintaining of a diet and a sleep schedule

Certain medical conditions may also increase your risk of sarcopenia, Chen adds, for example, pancreatic disease and type 2 diabetes, which affect the metabolism, as well as the hormonal conditions that affect the prostate. testosterone production essential for muscle mass.
Basically, genetics is mixed with other triggering conditions and bad lifestyle habits. as an unhealthy diet, you will lose muscle at a faster pace. Your best bet? If you know that you're going to have a harder time maintaining your muscle mass as you get older, start exercising and bodybuilding earlier in life and eat a balanced, healthy diet to prevent metabolic or hormonal problems. .
