1. What are the ways of swimming
1. 1. There are a total of 5 swimming styles in swimming, including backstroke, breaststroke, freestyle, butterfly, and snorkeling. Only snorkeling is not allowed because snorkeling can cause stomach pain.
2. 2. Generally, breaststroke is learned first. Breaststroke does not require as high a level of joint flexibility and strength for learners as other swimming styles, so breaststroke It is relatively easy to learn and practical (generally, breaststroke legs are used to tread water in the water).
3. 3. After learning breaststroke, you can then learn freestyle; freestyle requires the cooperation of hands and feet and needs to be practiced slowly. After practicing freestyle, you can Learn butterfly stroke or backstroke; if you are interested, you can also learn other fancy swimming styles; amateur swimming usually involves more breaststroke and freestyle swimming.
2. What are the swimming methods
1 , International competition events require that there are five swimming events: freestyle, breaststroke, butterfly stroke, backstroke, and individual medley. In actual swimming, there are also side swimming, reverse breaststroke, dog paddle swimming, etc. The formal events are as follows:
2. One of the swimming events. In 1896, the first Olympic Games began to be listed as an official event. Freestyle is not restricted by any posture, crawling is the fastest, and crawling has become the only posture of freestyle. The crawling stroke is like crawling, that is, taking turns to stroke with the arms and kicking the water up and down with the legs. This posture has reasonable structure, low resistance and uniform speed. It is currently the fastest and most labor-saving swimming posture in the world.
3. Freestyle is highly practical and plays an important role in Olympic swimming competitions. Olympic freestyle event men\’s 50 meters, 100m, 200m, 400m, 1500m, 4×100m relay, 4×200m relay 7 events; women’s 50m, 100m, 200m, 400m, 800m, 4×100m relay 6 item. Freestyle events account for 13 of the 31 events in all swimming events, and medley and medley relays also include freestyle. Therefore, freestyle is often regarded as a symbol of a country\’s swimming level.
4. The basic technical characteristics of freestyle swimming are that the human body lies prone in the water, with the head and shoulders slightly above the water surface. When swimming, the torso rolls left and right around the longitudinal axis of the body appropriately. The arms take turns stroking to propel the body forward. After your hands enter the water, the paddling route will be S-shaped, and your breathing and paddling movements should be coordinated. As your arms stroke hard, use the troughs formed by the water flow on both sides of your head to inhale.
5. Before the 1950s, swimmers attached great importance to the role of their legs in kicking the water. They usually took turns with their arms to stroke once and kick their legs 6 times. . Later, scientific research materials proved that the energy consumption of kicking is much greater than that of arm strokes, and the power to propel the body forward mainly comes from the arm strokes. Therefore, modern arm-based freestyle technology attaches great importance to the arm stroke and the cooperation of the two arms. The kicking action has been reduced to 2 or 4 times in long-distance swimming. But in short-distance swimming, most athletes still kick their legs 6 times.
6. Breaststroke is an ancient swimming style. According to records, swimming similar to this style existed in China, Rome, and ancient Egypt as early as 2,000 to 4,000 years ago. On August 24, 1875, the famous swimmer M. Webb used the breaststroke stroke to cross the English Channel in 21 hours and 45 minutes. The breaststroke was the first stroke to be used in competitive swimming in the early 19th century. However, due to the slow speed of breaststroke, sidestroke and crawl stroke appeared in the competition, and fewer and fewer people used breaststroke. It was not until the 3rd Olympic Games in 1904 that breaststroke was separated from other strokes. From 1924 to 1936, the biggest innovation in breaststroke was that after the stroke, the arms no longer moved forward from the water. Instead, the arms were moved in the air but the breaststroke kicking and leg-clipping movements were still used. A deformation of the breaststroke – butterfly stroke – appeared.
7. In 1936, the International Amateur Swimming Federation supplemented the breaststroke rules and allowed the butterfly stroke technique to be used in breaststroke competitions, so butterfly stroke replaced breaststroke. At the 14th Olympic Games in 1948, only one person used breaststroke in the 200-meter breaststroke final. In the breaststroke competition of the 15th Olympic Games in 1952, all athletes used butterfly stroke technology. So the International Amateur Swimming Federation decided to separate the butterfly stroke from the breaststroke event. Since the 16th Olympic Games in 1956, butterfly swimming has been listed as an official event. At that time, the rules also allowed breaststroke to be carried out underwater. Since swimming underwater is not affected by wave resistance, the horizontal posture is good., less resistance and faster than breaststroke on water. So at the 16th Olympic Games in 1956, almost all breaststrokers competed in the long-stroke diving breaststroke. Japanese athlete Masaru Furukawa set a world record in the 200-meter breaststroke with a time of 2′34″7. After the 16th Olympic Games, the International Amateur Swimming Federation revised the breaststroke rules, canceled the diving breaststroke, and only allowed one long stroke after starting and turning, and then the head must be above the water for each movement. As a result, the surface breaststroke technology was restored and developed, and the standards for breaststroke world records were redefined. For example, the men\’s 100-meter breaststroke is 1′13″0. In 1957, Chinese athlete Qi Lieyun first broke this record with a score of 1′11″7. Since then, the breaststroke techniques of wide arm stroke and narrow arm stroke have appeared.
8. One of the swimming events. Developed from breaststroke, it was the last to be developed among the four competitive swimming styles. In 1956, the 16th Olympic Games began to be listed as an official event. Because the swimming movement looks like a butterfly, it is called butterfly swimming. After the separation of butterfly stroke and breaststroke, butterfly stroke technology developed rapidly. In the past 10 years or so, the butterfly stroke technique has been to stroke once with both arms at the same time and hit the water twice. This swimming method is represented by the butterfly swimming technique of M. Pitts, the 100-meter and 200-meter butterfly world record creator at the 20th Olympic Games in 1972. During butterfly swimming, the body lies prone in the water and relies on the powerful strokes of the arms and the wavy kicking action of the legs to propel the body forward. There is no fixed body position.
9. ① Movements of the trunk and legs: When kicking, keep the feet together naturally, use the waist and abdomen to exert force, press the shoulders and lift the hips, and drive the legs backward and downward Make a whip-like movement to draw water. When you bend your knees to push down, lift your hips and tuck your abdomen slightly, and straighten your knees at the end of the kick. When pumping water upwards, the main purpose of pushing the abdomen slightly is to push water downwards with force. The range of the up and down movement is about 40 to 50 centimeters between the feet.
10. ②Arm technology: The arm stroke plays the main propulsive role in butterfly swimming. The paddling technique includes the stages of entering the water, paddling, and moving the arms. Both arms enter the water on the extension line of the shoulders. The order is hands, forearms, and the elbow joint of the upper arm enters the water last. Relax your arms when entering the water, do not press your arms but your shoulders. After entering the water, the position of the head and shoulders should be lower than the elbow joint. After the arms enter the water, with the inertia of the body moving forward, the hands continue to spread outwards, and then the hands turn inward to make a hook and hold the water. At the same time, slightly lift the elbows and stretch the shoulder girdle muscles. At this time, the distance between the two hands is the widest, forming a good water-holding posture in front of the head. At this time, the forearm is at an angle of about 45° with the water surface and starts paddling. The hands stroke from the outside to the inside, back and downwards, and the distance between the two hands is close when they reach the bottom of the head. Some athletes have the closest distance when they row below the shoulder, about 10 centimeters. Then push the water back. When pushing the water along the lower part of the chest and abdomen, the hands gradually spread apart and try to maintain the backward position facing the water. When the elbow joint is close to the side of the body, both hands quickly push the water outward and backward, and use the elbow as the fulcrum to end the stroke.Move your arms forward. As the inertial speed of pushing the water ends, bend your elbow and quickly lift your hand out of the water. After the arm comes out of the water, the shoulder drives the upper arm and forearm, and quickly moves forward along the water surface. The arms should be relaxed naturally when moving the arms and should not be raised too high. The shoulders are now in a higher position. When the arms go beyond the shoulders, the shoulders begin to press down, but the arms are still moved forward.
11. ③Breathing and coordination techniques: When your arms enter the water, start to exhale evenly through your nose and mouth. When pushing the water, raise your head, open your mouth to inhale when your hands come out of the water, and hold your breath when moving your arms over your shoulders. The key points for leg and arm coordination are: the first kick when the hands enter the water, the second kick when the hands push the water, and the kick ends when the water is pushed. During the second kick, the knee bend angle is larger and the kick force is greater.
12. One of the swimming events. In 1900, the second Olympic Games began to be listed as an official event. Backstroke includes reverse breaststroke and crawling backstroke. Reverse breaststroke is the earliest form of backstroke. The movement is similar to breaststroke, but the body posture is opposite. That is, the human body lies on the water surface on its back, and the two arms stroke the water backwards from behind the head through the sides of the body. Backstroke events at the first few Olympic Games were conducted in a reverse breaststroke stroke. At the 5th Olympic Games in 1912, American athlete H. Hebner used the backstroke technique of taking turns paddling with his arms and kicking the water up and down with his legs. He won the 100-meter backstroke championship with a time of 1′21″2, demonstrating the crawling backstroke technique. Technical superiority, while reverse breaststroke gradually loses its significance in competition.
13. The coordination movements of crawling backstroke are the same as those of freestyle swimming. Basic techniques include body posture, leg and arm movements, and breathing and movement coordination.
14. ①Body posture: During backstroke, the body lies almost horizontally in the water, with the chest naturally stretched in line with the abdomen, the head submerged in the water, and the face exposed. . When swimming, the head always maintains an upright posture, and the torso naturally rotates around the longitudinal axis due to the alternate paddling action of the two arms.
15. ②Leg technique: There are three functions of the legs during backstroke: one is to push the body forward, the other is to maintain the body\’s balance, and the third is to keep the body in a relatively stable position. High level posture. The kick of the legs is slightly larger than in freestyle swimming. When pumping water, use the hip joint as the fulcrum and use the thighs to drive the calves and feet to kick upwards. When kicking upward, the knee joint is slightly bent, making an angle of about 140°, the ankle joint is extended, the foot is turned inward, and the movement should be strong. When pumping water downwards, the knee joints should be naturally straightened, and the maximum distance between the two heels should be about 40 to 50 centimeters. When kicking, turn your toes slightly inward to increase the kicking area.
16. ③Arm technology: Arm technology is divided into several parts: entering the water, holding the water, paddling, coming out of the water and moving the arm in the air. Several movements are performed in a coherent manner. conduct. When entering the water, straighten your arms naturally and extend your hands with your little fingers facing down.In front of the line, the arm enters the water. Holding the water, when the hand enters the water, slide it outward, then hook the hand upward and backward with the palm of the hand. At the same time, the shoulder is internally rotated, the elbow joint is pulled forward and downward, the hand continues to be lifted, and the shoulder girdle muscles are stretched to make the hand and forearm Correct the direction of the stroke. The stroke is the main part of the movement. Start with your arms holding the water at an angle of 40 to 50° to the longitudinal axis of your body, and start paddling with your arms bent. The backstroke of your hands should be faster than your elbows. When paddling to the shoulder side, your hands are about 15 cm away from the water. At this time, the hands, forearms, and upper arms push the water backward at the same time. When the elbow joint is close to the side of the body, press the water backward and downward with the hand, rotate the shoulder joint upward and internally, and end the stroke when the palm turns inwards and presses down to the side of the thigh. After the stroke is completed, use the reaction force of the downward pressure of the palm to drive the upper arm and forearm out of the water with the shoulder lift. Relax the hand. After the arm comes out of the water, move forward along the shoulder line and straighten the arm. The cooperation of the two arms is that when one arm enters the water, the other arm comes out of the water.
17. ④ Coordination of breathing and movements: Since the face is exposed to the water, breathing is more natural. Generally, inhale when the right arm comes out of the water, and when the arm is vertical to the water surface Finish inhaling, then hold your breath, exhale evenly after your hands enter the water, and end when your hands come out of the water. The coordinated movements of the arms and legs are generally 1 stroke with each arm and 6 kicks with the legs.
18. One of the swimming events. In 1964, the 18th Olympic Games began to be listed as an official event. Individual medley is an individual all-around event. The competition is in the order of butterfly, backstroke, breaststroke and freestyle, with each swimming 1/4 distance. To complete four swimming postures at the same time, athletes must have a good overall training level. To achieve good results, they must also have outstanding results in a certain event.
3. How to swim
1. Don’t learn anything first As for posture, you must first overcome the fear of water. This is a very important level.
2. If you shrink back and sink in place, you will find that you cannot sink completely. You will feel that your density is smaller than water and you can float
3. Stand in the water, kick your feet back, and slowly tilt your body. At this time, your head is directly buried in the water, your feet are pumping up and down, and your hands are paddling back. You can move completely by instinct. .
4. After swimming for about 10 seconds, try your best to lift your head out of the water, take a breath, and it will naturally sink again. Just continue with the previous action.
