People with good genes are able to rehabilitate their muscles faster

The body's interaction with cardiovascular fitness and muscle strength is governed by genes.

Genetic variation affects physical fitness

The researchers found that a number of genes are responsible for how the body reacts to cardiovascular fitness, muscle strength, and anaerobic strength training. They note that people with good genes are able to get fit faster, revealing how genetics influence exercise outcomes.

London A new study revealed  the genes of "good" are able to rehabilitate their muscles and get fit faster.

Researchers from Anglia Ruskin University in Cambridge reviewed 24 previous studies to determine how genetics influence exercise outcomes.

For one set of exercises designed to improve muscle strength, the team found that genetic variation accounted for 72 percent of the variance in fitness outcomes.

The researchers concluded that 13 genes are responsible for how the body reacts to cardiovascular fitness, muscle strength, and anaerobic strength exercises.

Based on their findings, the team suggested that genetic testing could be used to better tailor exercise to each individual to achieve the best results.

"We know that exercise is good for us, but we all improve at different rates, even when following identical training regimens, and this means that other factors play a role," said lead author and sports scientist Henry Chong, from Anglia Ruskin University.

In their study, Chung and colleagues reviewed 24 previous studies and analyzed trial results in a total of 3,012 adults between the ages of 15 and 55 to assess how genetics might influence the impact of three important areas of physical exercise.

Genetic testing can be used to better customize exercises for each individual to achieve the best results

Specifically, it was this anaerobic strength, cardiovascular fitness, and muscle strength - which, the team explained, are the key factors in shaping an individual's fitness, quality of life and well-being.

In each trial, all participants showed improvement in physical fitness after their exercise training, but to varying degrees even when the subjects were following the same exercise routine.

"Our study found 13 genes involved in exercise outcomes, and we found that the specific alleles present in these genes are more relevant to certain aspects of fitness," Chung explained.

"For example, with repetition exercises designed to enhance muscle strength, genetic differences explained 72 percent of the variance in outcomes between people who followed the same training."

Because everyone's genetic makeup is different, our bodies respond slightly differently to the same exercise.

Therefore, it is necessary to improve the effectiveness of an exercise regimen by determining a person's genetic makeup, and then designing a specific training program just for him.

This can particularly benefit those who need to see improvements in a short period of time, such as hospital patients - or elite athletes, where marginal improvements can mean the difference between success and failure.

The researchers also found that genetic differences were responsible for 44 percent of the differences in outcomes seen after cardiovascular fitness and 10 percent of the differences after anaerobic strength training.

Understanding DNA enables athletes to develop their physical abilities

They explained that the remaining differences are influenced by other factors, including diet, nutrition, recovery and injuries.

The researchers emphasized that recent years have witnessed a remarkable rise in DNA testing of sports teams, coaches and athletes. Although this topic has become a subject of widespread controversy, the idea of ​​relying on genetic information in order to know the mathematical abilities of a person is a very exciting idea from a scientific point of view.

Experts pointed out that everyone has their own unique DNA that cannot be changed, and it affects people in very different ways. .

But just having the right DNA doesn't necessarily improve their abilities. Knowing and understanding DNA and how it affects humans is what enables top athletes to take advantage of these genetic trends, and thus develop their physical abilities.

Achieving a high level of physical fitness requires many months of hard training. Although the strength that the individual will have thanks to this, may fade quickly if he stops training, this does not necessarily mean that in this case he will have to start from scratch again.

It is not easy to gain high physical fitness or good health. Some may wonder, after making a great effort in exercising to achieve this goal, about the period of time during which they will be able to maintain this distinguished physical condition. Studies have shown that no matter how much effort is put into training to reach a distinct level of fitness, stopping those exercises for a period may lead to individuals becoming “unfit” much faster than it took them to reach that level. .

And to know how a person can lose the fitness he gained thanks to sports if he stops exercising; First he has to understand how he can get physically fit. The main element, which leads to this state, whether it is embodied in the form of increasing muscle strength, or improving the status of the heart and blood vessels, which is known as “cardiovascular fitness”, is to exceed the “usual load”, that is, to make one’s body exert More effort than usual. Here, the pressures that the body is exposed to, make it more adaptable to that extra effort, and more endurance as well, which in turn leads to its acquisition of higher rates of physical fitness.

Henry Chung: With repetition exercises designed to enhance muscle strength, genetic differences explained 72 percent of the variance in outcomes between people who did the same training.

The time that an individual needs to acquire this fitness depends on a number of factors, including age and level of fitness from the origin, in addition to the amount of effort he puts into training, and even the environment in which he is training. Pollution and high temperature may affect, for example, his physiological response to those exercises.

However, some studies indicate that an individual may need only six sessions of intermittent training, to increase what is known as “maximum oxygen capacity”, a term that refers to “the largest capacity that the body can absorb of oxygen, if it makes the maximum effort possible in minute.” The level of this capacity is one of the measures by which one can identify the general level of fitness that a person has. These sessions can also improve the body's ability to revitalize its limbs during exercise, by using sugars stored in cells.
