Chances are, you’ve probably heard before that every body is different, and on a physical level, it’s true. Some bodies, for example, are more likely to wear muscle than others. Actress Brittany Snow said she was in the camp, but she spent some time admiring it.
“At the age of 30, I looked at my life, aware that she has been on a diet, try to do the size of a model, I think I’m 5 ‘3”, and I inherited my mother’s beautiful muscular body – this is not going to happen, “she told the Shape.
Snow is not alone – some people are really destined to have sports, muscular body types, while others work hard to increase muscle size. Dr Jonathan Mike, an exercise physiologist, said: “[Predisposition] is primarily a combination of genetics and hormonal factors.
While fitness and nutrition are clearly key to exercising daily exercise, hormones play an important role in gaining muscle mass.
“Testosterone, human growth hormone and insulin-like growth factor are particularly important here,” explained lead scientist Dr CACSIC Bryant of the American sports association.
Although men have more testosterone than women, it exists in everyone and affects muscles in many ways. “Testosterone interacts with neuromuscular systems to help stimulate protein synthesis,” Bryant explained. Protein synthesis is essentially how to grow muscles (not protein degradation, muscle breakdown). “Enhancing protein synthesis can enhance some of the molecular pathways that enhance muscle mass,” says Mike.
The effect of testosterone on muscles is twofold. In addition to its own role in protein synthesis, it also stimulates the release of growth hormone in the pituitary gland. “The main role of growth hormone is to increase the availability of amino acids needed for protein synthesis,” Bryant said. “Growth hormone also stimulates the release of insulin-like growth factors in skeletal muscle, which together stimulate muscle growth.
These hormones also help regulate the activity of satellite cells, which activate satellite cells when there is a muscle injury, such as exercise. These satellite cells help repair and build damaged muscle fibers that are becoming larger and larger.
In short, the more these hormones, the greater the impact on muscle size and strength.
Everyone’s body is different. For example, you have the type of muscle fiber that affects your ability to build muscle.
Hormone levels are partly inherited, but may also be affected by training programs. “You can have a training program that emphasizes and manipulates the endocrine system, so you can increase the production of these muscle hormones,” Bryant said. Specifically, you’ll see the biggest changes in muscle building hormones, including weight lifting, including multi-joint exercise, recruiting large muscle groups such as squats, weights and bench presses. (it’s worth noting that, in general, hormones can also be affected by fluctuations in sleep, stress and nutrition.)
However, other factors that affect muscle are completely out of our control. “The makeup of our muscle fibers is genetically different,” Bryant explains. “Some people tend to have more rapid muscle fiber, while others have more slow-twitch muscle fibers.” Fast twitching fibers have explosive power, such as sprinting, high-intensity exercise, which are larger in size and have greater potential for development than slow muscle fibers. “If you’re someone with a high percentage of fast muscle fiber, you’ll be able to get more fat (or muscle growth) because you have this genetic material,” says Mike.
Genetics also determines how sensitive or sensitive your body is to the process of building muscle, but science can’t fully explain it.
“Two people may have the same hormone or muscle fiber concentration, and they may respond differently to training because a person’s system may be more sensitive,” Bryant explained. “It’s one of the emerging areas of research, and people are starting to pay attention to why you see these differences.” This could be anywhere in the chain of events, he said. For example, there may be differences in the sensitivity of pituitary to testosterone and how satellite cells respond to damage.
What we do know is that everyone is different, and trying and changing your body type can be exhausting (and often ineffective). Snow got the right idea: the best thing you can do is to appreciate your body’s natural greatness. After all, it’s your only one.
