How exactly are muscles formed? And how to get fit?

Muscles are mainly formed through the conversion of glycogen in the body, so we should practice more anaerobic exercises when exercising. This allows you to build your muscles more effectively.

It is formed by repair after a muscle tear. The reasonable fitness. There will be a slight tear in the muscle after a lot of exercise, and the muscle will become larger after repair.

The number of muscle cells is fixed since birth. Muscle building refers to the state in which cells go from inactive to active, so we need to make a reasonable fitness plan step by step when we work out.

Muscles can only grow by doing resistance exercises, and general strength training is an resistance exercise, which first destroys muscle fibers through exercise, and then repairs the broken fibers with protein, and the repaired muscles become thicker.

As a result of long hours of exercise, muscles slowly accumulate.

There is a theory that Darwin said for a long time - using the theory of entry and retreat, if you really don't exercise muscles for a long time, the muscles will become weak, and if you don't move for a long time (including not doing anything in life), I think the muscles will atrophy.

Muscles are made up of fibrous tissue. It emits a lot of force and sometimes injures the fibrous tissue of the muscles, but it is beneficial for muscle formation. Injured muscle cells release substances called cytokines.

When cytoactive horins are released, the immune system is able to ** the wound.

After the fibrous tissue of the muscle is injured, it is injured again, and so on ......and so onThe muscles will get bigger. If you repeat this cycle, your muscles will become stronger and more powerful.

Originally, the muscles of the body have adapted to the necessary activities of daily life. Therefore, in daily life, the body does not overload muscle growth.

Therefore, the hypertrophy mechanism that "makes" new muscle is necessary. That is, by exercising more than usual to make the muscles bigger. It is well known that if the muscles are not continuously burdened, muscular atrophy will occur.

Rather than promoting muscle growth by increasing muscle load, a "counter-muscle contraction" exercise that stretches muscles while exerting force is more effective.

While it promotes muscle growth, training is really important ......But without nutrients, injured muscles can't recover.

Protein ingested from food is converted into amino acids in the body, and then converted into protein again to form muscle. Insulin, which promotes protein formation, and testosterone, which promotes muscle formation, are also important for muscle growth.

In addition, the process of repairing and growing injured muscles is most active during sleep. In other words, sleep is important for muscle growth.

Gender and age are also closely related to the process of muscle formation. This is the reason why young men who produce a lot of testosterone are more likely to do well in bodybuilding championships.

Moreover, muscle growth is also related to genetic factors. As we all know, people who are genetically prone to muscle growth have a constitution that is prone to muscle growth. Still, the most important thing about growing muscles depends on how we treat them. If the right exercise is performed......

Get plenty of protein and other nutrients ......

Repeat training and rest ......

The muscles will be strong and strong.
