First of all, talk about the power of boxing. What is the level of 400 Jin? Ordinary people can reach this level with a little training.

1, let's talk about theory first. High school students have studied the impulse and momentum of physics, FT=MV. If you use the speed of 10 meter per second, because the human body is soft, the hitting time will be longer and the hitting time will be longer. Coupled with the softness of the muscles and bones, the hitting time is about half a second. In this case, as long as you can accelerate 20 kilograms per second to 10 meter, you can hit a ton. What is the concept of ten meters per second? Running is the world champion level, but people's hands are faster than their legs, and many well-trained people can do it. How many kilograms does a person's arm weigh? There must be five kilograms. In fact, why do you punch from your legs? You just want to put as much weight on your arm as possible. So people's punches, with a little training, can sound terrible and can't move hundreds of kilograms. Tai Sen punches at least 500 kilograms, because the boxing of the world batting champion can reach 900 kilograms. It would be too bad if Tai Sen can't even reach 500 kilograms. But it is true that one kilogram is almost equal to 2.2 pounds. In other words, Tai Sen's fist at least exceeds 1000 pounds.

2. Test in the experiment. Both "Seeing Wushu Scientifically" filmed by Americans and "Revealing Sports Competition" recently released by CCTV have proved that the power of punching can easily reach several hundred kilograms, and wrestling is the most terrible force in fighting. In the experiment, crazy Jackson threw a dummy, causing more than ten tons of force, which is equivalent to a truck hitting a person at a speed of 30 kilometers. This is measured by instruments, not a rumor that some people think out of thin air or hear.

3. The strength and striking effect are different. Let's talk about what is the impact force first. The impact force refers to the peak force. That is to say, the F force generated by the instantaneous force acting on an object should be Newton, not kilograms or pounds. This means the mass or weight caused by the gravity of the earth. We are pounds or kilograms, and we also use the conversion under the gravity of the earth, mainly for the convenience of understanding. The strike effect is not only related to the peak strength, but also related to the sustained strength. The damage caused by a ton of force lasting 0. 1 sec is different from that caused by a ton of force lasting 1 sec. Then there is the pressure effect. It's useless for you to hit anyone with one punch and five pounds of strength, but it works on the needle to ensure that all qigong is the same.

4, the same force, the impact effect is different, and the difference is very big. The most important thing is opportunity, not strength. In fact, if you watch a lot of games, you will find a lot of KO punches. In fact, boxers are unconscious and can't be heavier. There are three key points. The first is whether the opponent moves in the direction of your fist. If you hedge, even if the fist is not heavy at ordinary times, the actual strength is great, and the possibility of KO is great. The second and most important point is that when people see an attack, their muscles will instinctively tighten. Although this action will lead to stiff body and passive beating for untrained people, it will actually reduce people's injuries. Therefore, the attack that the opponent can't see is the easiest to produce KO. For example, your opponent is attacking, and as a result, you punch out from his perspective. The third is the hitting position. As far as boxing is concerned, the head rotation caused by hitting the chin, whether up and down or left and right, is the easiest to KO. The last two reasons explain why reverse swing kick (called backspin kick by many people who don't understand it) is actually very weak, but it works well after hitting people, because it is a way to fight back. It is easy to cause visual out-of-shot and head rotation.

Finally, to answer your question, Bruce Lee's striking power is not well proved. There is a 400-pound rumor on the Internet, which comes from a book written by some so-called experts in early China. I am speechless. Many people who practiced interception in the early days did not have a high educational level, but after a lot of theoretical explanations and experiments, it is proved that Bruce Lee hit 400 Jin, which can only be said to be a slander against Bruce Lee. Tai Sen's strike force is at least 65,438+0,000 pounds. I remember reading the information, but I can't remember where I saw it, so I can't provide evidence. But in the K 1 competition, Mr. Perfect and the Dutch lumberjack both hit their legs more than one ton, that is, more than 2,500 kilograms. You can find many such things on the Internet. You can think about it. Bruce Lee weighs only 400 pounds. Are you kidding?

The attack of nunchakus has no actual data, but it is easy to calculate. For example, the nunchakus you use are made of standard wood and weigh 300 grams, which means that the center of gravity you throw is 150 grams. Because nunchakus are small moments that people use to push big moments, the speed can be about three times that of people. Let's use 30 meters/second to calculate. So if you hit a brick, because the moving distance is small, it is about 4500 kilograms. But if you hit the head, it will drop to 1000 kg to 2000 kg, and if you hit the stomach, it will be less than 500 kg. Bars are different. The strength of that thing depends largely on people's hands to increase weight, so it can't be calculated directly according to the weight of the bar itself. But as far as estimation is concerned, it will be smaller than nunchakus and not much worse.

The power algorithm of knife is special. If the knife is sharp enough, it basically has nothing to do with strength. Theoretically, a one-handed knife is more powerful than a throwing stick, but in fact, because of the great pressure, its destructive power is far greater than all stick weapons, unless the opponent wears hard armor. But this is basically impossible in modern society. Body armor can only prevent blunt bullets, not stab wounds. If you have a sharp knife in your hand, even if it's just a dagger, you only need 5 kilograms of force to cut people's aorta. Bruce Lee filmed nunchakus facing the knife in the movie, but he himself said that nunchakus can't beat the knife in actual combat if their strength is similar. This is an interview with Bruce Lee. There is a download in the electric donkey called Bruce Lee, an artist of life. I went down to see it myself, and it was there. I just don't know if I can find this resource now. The police are equipped with stick weapons, because their goal is riot prevention rather than killing people. Otherwise, why are the troops equipped with knives instead of sticks?

I am five years old and have been practicing martial arts for more than 25 years. I have come into contact with a large number of surgical cases in internal medicine surgery. In this respect, I think I am a rare authority in China.
