DO GENETICS HELP IN MUSCLE GROWTH?

What is Genetics?

Genetics is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. Almost 50% of your body composition is determined by genetics.

Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.

So, do genetics actually affect your muscle growth?

There are controllable factors that involve how you live, eat, think, and train. If your training, diet, and lifestyle are perfectly suited to maximize muscle growth in your body. The only thing limiting muscle growth and strength gains would be uncontrollable factors, such as your genes.

Although how you eat, move, and live can have profound effects on your bones. Including your overall structure and the strength of your bones. Your bones are also hardwired to have limits and to follow a genetically preset potential of possibilities.

Your genetics also determine how responsive your body is to resistance training in general. Building muscle is an adaptation process If you consider everything that happens in your body from signal to change, it is very a complex process.

Some people’s bodies respond well to resistance training, regardless of all the above factors. Due to the complexity of the process, we do not know why necessarily. But responsiveness in each person’s body is likely due to genetics.

The ability to change body composition is essential for bodybuilding, but so is power. Power sports, like bodybuilding and weightlifting, require short bursts of big force. Endurance sports, like distance running, require less force generated over a longer period.

Strength training and exercise, in general, require training and hard work. However, your genes also play a role. Some people have a genotype that makes them better at power or endurance. Much of this is related to muscle fiber type. If you naturally have more type I fibers, you are more likely to be good at endurance. If you have more type II, fast-twitch fibers, power is your strength.

Several genes have been studied in relation to muscle building. Genes can determine how easy or difficult it is to build muscle mass up to a certain extent. Genetics influences your body type, muscle composition, and your response to diet and training.

One of the genes that determine body composition is:

IGF1 Gene
The IGF1 gene encodes a protein called Insulin-Like Growth Factor. IGF1 is an anabolic hormone that stimulates the growth of muscle, bone, and several other tissues in the body. It stimulates protein-building processes. This hormone aids in muscle building through a process called hypertrophy. Hypertrophy refers to the increase in muscle mass through exercise. Variations in this gene can determine how easy or difficult it is to build muscle.


CONCLUSION:

The bottom line is that your genetics play a massive role in how big and muscular you can get or look. Know that you are nowhere close to your top potential. Although very few people have gene or bone structures that generate millions of followers or win physique contests, everyone has the potential to look impressive to the average eye.
