Bruce Lee has made many films, and we have seen many Bruce Lee films, such as Big Brother in Tangshan, Long Hudou, death tower, The Raptor Crossing the River and so on. And we have seen the video of Bruce Lee fighting. In the Biography of Bruce Lee a few years ago, Bruce Lee punched and kicked very fast, which can be reflected not only in the opening and fighting of the film, but also in Bruce Lee's body. How many punches can he punch and one punch a second? First of all, in terms of biology and mechanics:

Biology, punching, closing and punching are a continuous action, that is, muscle contraction and extension. After training, people's exercise will increase. In the animal kingdom, many insects are very fast. For example, flies can flap their wings hundreds of times per second, and hummingbirds can flap their wings hundreds of times per second. Large animals, such as running antelopes and leopards, can generally reach dozens of times per second, which means that the speed reaches 160 km, which can be said to be the limit, so 160 km is 36,600 km. 160000/3600/2=22.2 times, so the speed of people can't reach the speed of top animals, which is estimated to be about 2/3, so it is 14 times, which means that Bruce Lee's punching speed reaches 14- 15 times per second.

Then the speed of kicking is basically not fast, because kicking is more difficult, it will consume more oxygen and energy and produce more propionic acid. Then the kick speed is estimated to be around 8- 10 times. According to the speed of the world track and field competition 100 meter champion, 100 meter is more than 9 seconds, and one step is about 2 meters, that is, 100/9/2=5.5 times, but the kick is fixed, as long as the thigh does not retract, and the calf kicks relatively.

Human movement is not like mechanical movement. The speed of mechanical movement, such as the speed of the engine and wheels, is very fast. For example, if the speed 100 km and the wheel circumference are estimated as 1 m, then it can reach 1 00000/3600/1= 27.8 times, which means that the average wheel of an automobile is1time.

If you watch videos, Bruce Lee is really fast. How fast? We can still see video reports about Bruce Lee.

Therefore, Bruce Lee's punching and kicking speed is really fast, and Bruce Lee studied hard and learned from many martial arts masters, and many of them were trained in actual combat.
