What are the limits of human muscles?

The limits of these human bodies are unknown to most people.

To sum up, the release of potential made by the body should be attributed to our adrenaline and norepinephrine, which are secreted sharply in moments of intense tension. The role of epinephrine and norepinephrine is to cause excitement in animals or humans. Specifically, it causes an increase in blood pressure, a faster heartbeat, an increase in metabolic rate, an increase in cellular aerobic capacity, vasodilation, a large number of red blood cells in the spleen entering the blood circulation, increased blood flow in skeletal muscle and heart, dilated pupils, and erect hair, while inhibiting the peristalsis of the digestive tube, vasoconstriction in the smooth muscle of the intestinal wall, and a decrease in blood flow to reduce unnecessary energy consumption in the body; At the same time, the muscle glycogen of skeletal muscle is broken down into glucose, and the muscle strength becomes larger, so that the energy available to the human body is greatly increased.

So we were able to do things that we couldn't normally do, because the mood at that time was so intense that we couldn't control it.

Regarding the problem of brain development, the capacity of the human brain cannot be cracked, if it is a computer, we can know how many things can fit in this computer, but the brain is different, we cannot know how much a person can remember and how much knowledge can be acquired.

Haha, I probably don't understand what I'm saying

Human muscle fibers do not carry a limit of more than 10 meters per second. In the 20th century, the theoretical limit of calculation was the second. According to the calculation of factors such as the resistance of the human body against the air and the reaction force of body weight on the ground, when a person runs at this speed, it will not cause muscle damage, but once this limit is exceeded, the human muscle will likely be split during running.

Later, the Dutch mathematician Professor Ainmaru studied various world records in track and field and came up with the human limit of 100 meters in seconds.

Human muscles are generally at the limit of strength at the age of 25.

There is also one that the Haier brothers said"Invincible explosiveness"

In other words, when a person encounters danger or when his life is oppressed, he or she can exert about twice as much force as usual.

Everyone has their own limits.

I once read in a book about an Egyptian man who was tested by the Egyptian military and found that each of his muscle fibers could hold 65kg of weight, and I don't know if it's true.

There are 639 muscles in the human body, which are made up of 6 billion muscle fibers, and each muscle fiber can produce about millinewton force when contracted, and if the 639 muscles of the whole body are contracted at the same time, about 25 tons of force can be generated. There are about 639 muscles in the human body, which are composed of about 6 billion muscle fibers, of which the longest muscle fiber is 60 centimeters, and the shortest is only about 1 millimeter. Large muscles weigh 2,000 grams, while smaller muscles weigh only a few grams.

The average person's muscles make up 35-45% of their body weight. The total length of capillaries in the muscles can reach 100,000 kilometers, which can circle the earth two and a half times.
