Snorkeling, specifically called butterfly diving leg pose.
The underwater speed of the submarine is faster than the surface speed, which is called overcoming the resistance of the waves.
It is precisely because diving can overcome the resistance of the waves, so you can see the Olympic Games before 1988, swimming competitors were diving as far as possible after diving into the water before surfacing, which eventually led to the Olympic Committee's stipulation that 15 meters must be surfaced.
However, diving has to hold your breath, and the dangerous and long-term training of diving will damage the body's organs, and it will eventually be abandoned by the Olympics.
Freestyle is not a swimming style, but refers to the swimming style that can be used arbitrarily, and the modified dog crawl is the fastest in the water stroke.

Breaststroke is best for exercising. In particular, it can create beautiful legs and waist curves.
The butterfly swimming posture is the most beautiful, like a mermaid.
Backstroke is the most energy-saving and suitable for self-rescue.
The order in which beginners learn to swim is best:
Breaststroke, Freestyle, Backstroke, Butterfly or Freestyle, Breaststroke, Backstroke, Butterfly Crawl, commonly known as freestyle. When swimming, crawling, swimming, the person is in a prone position in the water, the legs alternately hit the water up and down, and the arms take turns paddling, the movements are very similar.
Crawling, so people call it "crawling".
Crawling is the fastest of the four competitive swimming techniques, and is commonly referred to as "freestyle" because it is used by athletes in the freestyle event of swimming competitions (competitions that do not require a swimming style).
-
The fastest is of course freestyle! The premise is that you can swim!
-
Freestyle is the fastest form and is relatively easy to practice, taking care not to bend your knees.
-
Freestyle is the fastest.
The four swimming styles of formal swimming competitions are: breaststroke, freestyle, backstroke, and butterfly.
Freestyle is the fastest, and it is mainly driven by hand strokes, so group training with pull-ups can increase your swimming speed.
The breaststroke is the slowest and most persistent, mainly powered by the leg clamps, so regular training for long-distance running can improve the swimming speed.
The backstroke is the third fastest and less labor-saving, mainly driven by the stroke, so training the pull-ups on the backgrip bar in groups can increase the swimming speed.
The butterfly stroke is the second fastest and most spectacular, mainly driven by hand strokes, so group training with pull-ups can increase the swimming speed.
In addition, the diving breaststroke is the fastest swimming style with bare hands because of its low resistance.

From the large-scale swimming competitions from all walks of life, we can easily conclude that the speed of crawling is better, and everyone can draw conclusions in freestyle competitions, because the choice of crawling to compete also fully demonstrates the superiority of crawling in terms of speed.
So why is crawling faster than other strokes?
First of all, thanks to its body posture, in the process of crawling and swimming, the body lies prone in the water, the body is very close to the water surface, and the body presents a very good streamline from head to toe, plus the stroke action of turning, so that the resistance area is smaller, which is the guarantee of reducing resistance, and in terms of action, the freestyle is powered by alternate strokes of the arms and the alternation of the legs in the process of swimming, and this continuous cycle of strokes makes the freestyle almost non-existent pause when swimming, with turning the head to breathe, It can control the effect of breathing on the state of the body very well.
In contrast, the action of breaststroke is relatively disadvantaged, because breaststroke is provided by paddling forward with both arms at the same time, as well as the leg binding and water clamping action of both legs when swimming, and the water kicking action will produce relatively large resistance in the process of retracting the legs, and it is necessary to raise the head during the breaststroke ventilation, this action will directly affect the streamlining of the body, so that the shape resistance of the body increases instantly, for amateurs at the moment of raising their heads for ventilation, the power is almost directly reduced to zero, So every time you breathe you go through a pause, which greatly affects the overall speed of the breaststroke.
In fact, the butterfly stroke has many similarities with the freestyle in terms of action, including the arm stroke and leg stroke, but it changes from alternation to simultaneity, but the butterfly stroke is still relatively slow compared to the freestyle, which is because the butterfly stroke gets up and will cause a relatively large wave resistance, and the butterfly stroke action consumes more physical strength than the freestyle butterfly action.
Compared with the freestyle, we can clearly understand that the backstroke is not as fast as the freestyle, you can experience that the action is easy to do when lying on the stomach, or the action when lying on the back is easy to do, you can know the mystery of this, it is obvious that the state of lying on the stomach is more conducive to the force of the arm stroke. And most of the forward power** in freestyle and backstroke is the arm stroke.
There's a science behind why crawling is the fastest, easiest, and most efficient stroke. That's why so many people love freestyle.
-
It should be that the breaststroke swims the fastest. Because we swim in the breaststroke, we have a glide distance, and because of inertia, we can be very fast.
-
Freestyle is the fastest because it is more labor-saving and the resistance in the water is relatively small, so you can increase your speed.
-
Freestyle is the fastest. There are 4 types of swimming styles in the regular swimming competition, namely: breaststroke, freestyle, backstroke, and butterfly. The fastest of the four strokes is the freestyle, and the slowest is the breaststroke.
-
Freestyle, because the speed of freestyle is inherently fast, and when it comes to ventilation, the speed of the flow is really fast.
-
Crawling, at this time, will make the body appear streamlined, through the stroke can reduce the body's resistance, can make one's speed faster.
-
The butterfly leg is the fastest. At the Olympics, someone won a gold medal in the butterfly leg in the whole way, and we saw a new rule that the 15-metre pool must be exposed, which shows that the diving is good for performance, and the butterfly leg is the fastest in diving.
Characteristics of the swimming
Freestyle is characterized by extreme speed, and athletes generally choose freestyle to complete the race at the fastest speed when they are lying in the water.
Breaststroke is a swimming posture like a frog, it is arguably the oldest swimming style, in which the upper body of the person is leaned forward so that he can clearly see the front.
The most beautiful of the four swimming styles is the butterfly, which was born in 1937 and 1952 during this period, when the athlete swims with both arms to the thighs and then lifts the water surface, and then swings back into the water from the air, people are like butterflies dancing, so people call it butterfly swimming.

Freestyle or backstroke.
If you choose to swim fast at the same distance, the freestyle time is the shortest and most labor-saving, and if you swim slowly, it is backstroke, because you can rely on buoyancy to do it very relaxed.
If it is an informal race, the snorkel is the fastest, and the reason for the fastest snorkel is that the whole body is submerged in the water, so there is no need to switch back and forth between the air and the surface of the water in the reed hole, reducing the effect of drag. If it is an official competition style, it is freestyle, which can be seen from the current world records of each swimming style.
Freestyle is the fastest and most efficient stroke, and it is also the fastest stroke in competitive competitions, and freestyle can also achieve minimal physical exertion for long-distance swimming.
Freestyle is a very common swimming style because the left and right forces are evenly balanced, and the body is streamlined in the water, so freestyle is easy to swim with less effort and faster. Freestyle requires swimmers to lie on their stomachs, with the same leg movements as backstroke legs, crossing, up and down whipping, and hand movements requiring the arms to be returned from near the thighs to the top into the water, and then scratching and pushing the water to the vicinity of the thighs and then returning to the arms.
Which of the four strokes is the fastest? Which is the slowest? For starters, the question is simple. Freestyle. >>>More
Velocity of light. The speed of light is kilometers per second, some arithmetic problems in our physics or mathematics learning are often directly taken as 300,000 kilometers per second, the so-called speed of light refers to the speed at which light propagates in a vacuum or some medium, and we know that when light travels in a vacuum, the speed is the fastest. >>>More
