"How does muscle grow?" Explanation of its mechanism by animation

It is important to understand the mechanism by which muscles grow to make macho body of muscle muscles. If you understand the mechanism of muscle growth, you can do training effectively. Not only for those who want to become muscular muscles, but also for those who want to train themselves as part of their health promotion, movies that deepen their understanding of muscles easily "What makes muscles grow?"TED-EdIt is open to the public.

How does muscle grow?


There are more than 600 muscles in the whole body.


Muscles occupy one-third to one-half of their body weight.


Muscles allow us to compete and move.


Training is important to make your muscles bigger.


However, aside from whether or not you want to make your muscles bigger, muscles are important in living.


For example, consider the mechanism when standing in front of the door and opening the door.


First of all, the brain wants to open the door "through the nerve" ...


It transmits to the muscles of the arms.


The muscles of the arm who received the order from the brain change shape with shrinking and stretching ......


I will pull the bone. This is the mechanism that the force is transmitted to the door knob and the door can be opened.


What if it were a heavy-duty iron door? The brain changes instructions according to "opponent". If strong force is needed, I will send a strong order.


Also, I will issue orders according to the situation to the muscles of the arm as well as legs, abdomen and back muscles of the whole body.


You can open iron doors by changing the position and giving great power in the whole body.


The nervous system can combine the muscles of the whole body to produce great power.


The muscle tissue overlaps in a fibrous form.


Muscle fibers may be hurt by exerting great power, which is good for muscle growth.


Wounded muscle cells release substances called Cytokines (cytokines).


When cytokines are released, the immune system works to cure the wounds.


If muscle fibers are damaged, they are treated, they are injured and treated, and by repeating ......


Muscles grow bigger.


By repeating this cycle, the muscles grow stronger and bigger, and they will be able to produce greater power.


However, the muscles in the body have already adapted to the exercise required in daily life. Therefore, in daily life there is no burden of growing muscles.


So create a new muscle "HypertrophyIt is necessary to have a mechanism called called.


This is that the muscle grows by applying a higher load than the exercise you usually do.


A phenomenon "Muscular atrophy" is also known, in which the muscles contract when the muscles are not subjected to a continuous load.


Exercise called "eccentric muscle contraction" that exerts a force while extending the muscles is effective for promoting muscle growth with a heavy load.


It is certain that training is important for muscle growth ... ...


You can not recover damaged muscles without nutrition.


Protein to take with a meal ......


It turns into amino acids in the body, becomes protein again and makes muscle.


Insulin to promote protein synthesis and testosterone to promote muscle growth are also important for muscle growth.


The process of restoring and growing damaged muscles is most active when you are asleep. In other words, it is important to rest your body in order to grow your muscles.


Gender and age are also heavily involved in muscle growth mechanism. This is why young men who produce a large amount of testosterone are more likely to get good results at bodybuilding competitions.


Furthermore, genetic factors are also ants for muscle growth.


It is also known that 'genius' is involved in muscle growth, such as those who are genetically liable to grow muscle.


Nonetheless, how to deal with muscle is most important for muscle growth. Doing the right exercise ......


Protein and other nutrients are taken enough ...


Repeat training and rest ... ....


Muscles grow strong and grow big.
