Backstroke can also be called backstroke. The swimming style of lying on the water is a swimming style set by the International Swimming Federation. There are "anti-creep stroke" and "anti-breaststroke" in backstroke action. Because of its fast speed, the "anti-climb stroke" is used by athletes in competitions almost without exception.
When learning the essentials of backstroke, the nose and mouth are always on the water, breathing is convenient, but you cannot look forward, and the sense of direction is difficult to grasp. In swimming competitions, only the backstroke requires athletes to start in the water, and other swimming styles can start diving. Therefore, the backstroke is the second style in the individual medley and the first style in the relay medley.
Three conditions for a good backstroke
1. Light body and good buoyancy. This is congenital. Children and most young women have an advantage in this area, which is a hurdle for adults.
2. Good shoulder flexibility. Without a good shoulder, a backstroke swim is neither beautiful nor efficient. As long as you persevere and often swim backstroke, the flexibility of the shoulder improves faster than the other three swimming styles. Having a good shoulder is good for the other three swimming styles.
3. The water feels good. The requirements of backstroke for water feel are higher than the other three swimming styles. The other three swimming styles can swim by brute force, and even the speed is not slow. It is easy to get a sense of satisfaction. It can be backstroke without a good sense of water. Use brute force to swim and watch, almost do not move the nest, even the harder, the slower, making people easy to feel frustrated. If breaststroke and freestyle are the basic swimming styles, then backstroke is the best swimming style to improve swimming skills. The above three conditions have a certain degree of difficulty. I think these difficulties keep many swimmers out of the backstroke. main reason.
Many swimming enthusiasts say that the backstroke looks beautiful, but it feels uncomfortable to swim, which means that it doesn't help in some technical issues.
Backstroke knees cannot be bent
Many people always can't float up during the backstroke, and the problem is most likely in the leg movements. When backstroke, your legs must be stretched straight, knees and ankles should be straight, and your feet should be slightly inward. When kicking, the thighs must be pressed hard and the straight legs pressed down. There should be no pause when the legs alternate. Beginners can do some leg imitation exercises on land first to understand the essentials of the movements. In addition, the backstroke is not about lying down with your whole body relaxed, you must stand up your chest, tuck your abdomen, and gather your hips. Don't sit in the water, you will soon sink. If the movement is standard enough and you want to increase the speed, you must increase the frequency of kicks during the backstroke. Generally, an average of 6 kicks and 1 week of rowing is the standard frequency. The two arms should alternately stroke the water during travel, and it is best to keep 180 degrees between the two arms. Keep your arms straight on the surface of the water, and it is best to touch your ears with your big arms when your hands are in the water. After the hand enters the water, bend the wrist first, then the elbow, and then push the water hard when the hand reaches the position of the navel. It is recommended that beginners do imitation on the land first, do standing imitation first, and then do supine imitation after the movements are familiar. Some people complained about water in their noses during backstroke. In fact, this problem is very easy to solve, as long as the chin is as close to your chest as possible.
Backstroke breathing: Don’t let yourself always drink water. The backstroke posture determines that there is no ventilation technique at all, but the backstroke is the most drunk stroke. The water that comes out when the arm is swung is often all in the mouth, which is very choking. Uncomfortable. For this reason, some people tilt their heads slightly forward to reduce drinking water, but at the same time, the problem is that the speed slows down, so the choice varies from person to person. Backstroke focuses on the balance of the body. Unlike the other three styles, backstroke has no reference as the direction of advancement, so the force of the arms and the feeling of yourself are particularly important.
